Process and Steps
Steps to Take When Selling a Tenanted Flat
A tenanted flat sale has a different sequence to a vacant one. Some of the steps happen months earlier than they would in an empty-property sale, some need careful tenant handling, and one of them (serving Ground 1A) is genuinely committing in a way the old Section 21 process was not. This guide walks through what to do, in order.
A Different Sequence to a Vacant Sale
Selling a tenanted leasehold flat follows a different sequence to a vacant sale. Some of the steps happen months earlier than they would for an empty property, some need careful tenant handling and one of them (serving a Section 8 notice with Ground 1A) is genuinely committing in a way that the old Section 21 process was not. Section 21 was abolished on 1 May 2026 by the Renters' Rights Act 2025, and Ground 1A is now the route to vacant possession for landlords who want to sell.
This article walks through the practical steps in the order a landlord-seller actually takes them: the early decisions, the conversation with the tenant, the Section 8 notice and what to gather before serving it, the selling-tenanted route in parallel with the continuing tenancy, the cash-buyer route, the completion-day specifics and the common process pitfalls. For the broader question of whether to sell tenanted or vacant in the first place (and how a tenant in place affects price), see our topic guide on selling a flat with a tenant.
The structure is straight-line: decisions, then the conversation with the tenant, then the notice (if going the vacant route), then the marketing process (tenanted or vacant), then completion. Each section explains what to do, in what order, and what to keep records of as you go.
Where the Process Splits: Three Decisions Up Front
Before any notices are served or any agents instructed, there are three decisions that shape everything that follows.
1. The route
Three options:
- Sell tenanted with the tenant in place. No notice required. The buyer takes on the existing tenancy.
- Obtain vacant possession via Ground 1A, then sell on the open market. 4 months notice and a no-relet restricted period that runs to 12 months after the notice expires, but full open-market access once vacant.
- Auction (often a good fit for tenanted flats, since the auction buyer pool is investor-heavy). Can be tenanted or vacant.
The trade-offs between the three sit in the topic guide on selling a tenanted flat. This article assumes the route is decided and walks through the steps from there. The first practical step on any tenanted leasehold sale is a handful of lease-specific checks; the next section covers those.
2. When to tell the tenant
Will you tell the tenant up front, or wait until the route is chosen and the agent is on board? Almost always, up front is better. Agent visits, photographers and listings will give the game away within days; surprising the tenant with a Rightmove ad is a fast way to lose their cooperation for the rest of the sale.
3. Agent choice
Some estate agents handle tenanted sales as standard; others rarely see them. For a tenanted-route sale, an agent who has done several recently is worth more than the local high-street name. For a Ground 1A vacant sale, any leasehold-experienced agent will do, but ask whether they have handled sales where the tenant is still in the property during marketing (since photographers and viewings still need access during the notice period).
Leasehold Checks Before You Start
Before talking to the tenant or briefing the agent, a tenanted leasehold sale needs a handful of lease-specific checks. Most of these come up later in conveyancing anyway; running through them up front saves weeks if anything is amiss, and gives the seller a clear picture of any costs or consents that need to be sorted before completion.
Subletting clauses in the lease
Most modern leases allow ASTs (assured shorthold tenancies, the standard private rental arrangement) with reasonable conditions. Older leases sometimes prohibit subletting altogether, restrict it to approved categories or require explicit freeholder approval for each tenancy. If the lease prohibits subletting and the flat has been let on an AST regardless, that is a breach of lease the buyer's solicitor will raise during conveyancing. The usual fixes are retroactive freeholder consent (often with a fee), a deed of variation (a formal change to the lease, sometimes needed where a clause is genuinely problematic) or indemnity insurance (a one-off premium that protects the buyer against future enforcement of the breach). Worth reading the relevant clauses of the lease before listing the flat tenanted.
Freeholder consent for the existing AST
Even where subletting is permitted in principle, many leases require the leaseholder to obtain consent (or to notify) the freeholder for each new tenancy. Confirm that consent was given when the current tenancy started. If it was not, contact the managing agent now to request retroactive consent: the fee is usually modest (£100 to £300) but the issue can hold up a sale if it surfaces during conveyancing instead.
Notification, registration and consent fees
Some leases (and some managing-agent agreements) require an annual or one-off notification fee for tenanted flats. The buyer's solicitor will see these on the management pack and ask about them. If the seller has been paying them, the running cost transfers to the buyer on completion; if the seller has not been paying them, expect the buyer to want clarity on whether arrears are owed.
Block insurance and tenanted occupation
The freeholder's block insurance policy is the building's main cover, paid for by leaseholders through the service charge. Some block policies require notification of tenanted occupation and may exclude or limit cover for a flat let on an AST that has not been declared. Confirm with the managing agent that the policy has been notified of the tenancy. An undeclared tenancy can affect a future claim, and the question will surface when the buyer's solicitor reads the LPE1.
Pending Section 20 major works during a tenancy
Section 20 is the consultation procedure under the Landlord and Tenant Act 1985 for major works on the building. Pending works can mean scaffolding, restricted access, water shutoffs and noise during the tenant's occupation. The management pack will show any pending Section 20 notices. The buyer will want to know what is coming; the tenant has a right to be told about anything that affects their use of the flat. A tenanted sale where major works are about to start often gets renegotiated mid-conveyancing, particularly where the leaseholder cost share is large.
Lease length on a tenanted sale
On a tenanted sale, the lease length matters as much as on a vacant sale, often more. BTL (buy-to-let) buyers' lenders apply minimum lease lengths (typically 80 to 90 years remaining at completion, more conservative than residential lenders); below 80 years marriage value still applies under current LAFRA 2024 status; below 70 years few BTL lenders will lend at all. A short lease and a tenanted property compound the discount, sometimes to the point of making the property practically unsaleable to BTL buyers. The fix is the same as on any short-lease leasehold sale: extend before listing, accept the discount, or sell to a cash buyer (which on a tenanted leasehold flat means going the Ground 1A route first, since cash buyers buy with vacant possession).
Talking to the Tenant
Most landlord guidance skips this step. In practice it is the single most important non-legal action of the entire sale, because a tenant who feels respected is a tenant who lets the photographer in, agrees reasonable viewing windows and leaves on time. A tenant who feels blindsided is the opposite at every stage.
When to have the conversation
As early as you have decided to sell. If you are still weighing options, wait until the decision is firm; raising the possibility and then leaving the tenant uncertain for weeks tends to make things worse. Once you know which route you are taking and roughly when, get on a phone call (or visit if you are local) and explain.
What to say
Be direct. Most tenants would rather hear "we have decided to sell, here is what that means for you" than a softened version that leaves the timeline unclear. Cover the route (tenanted or vacant), the rough timeline, what you are asking from them practically (viewings, access for the photographer, notice-period cooperation if relevant) and where they can ask questions. A short follow-up email summarising what you said is genuinely useful: it gives the tenant something to refer back to and creates a record if there is any later disagreement.
What not to say
Do not promise anything you cannot deliver. Do not tell them they will definitely have until a particular date if the sale could complete sooner. Do not pretend the sale will not affect them. And do not threaten possession if they refuse viewings: tenants have a right to quiet enjoyment of their home (the implied covenant in every tenancy that protects the tenant from unreasonable interference by the landlord), and the practical answer to refused access is to switch to selling tenanted (or to wait for vacant possession), not to escalate.
The case for keeping them informed
An informed tenant who understands what is happening tends to be a cooperative one. Update them when the property is listed, when an offer is accepted, when an exchange date is set and when completion is fixed. None of this is required by law, but the cost of being courteous is zero and the cost of not being is sometimes a buyer pulling out because the tenant blocked a final viewing.
Serving a Section 8 Notice with Ground 1A
If the route is vacant possession via Ground 1A, this is the legal step that starts the clock. The mechanics are not complicated, but the consequences are real.
The prescribed form
In England, the notice is given on the prescribed Section 8 notice form, available from gov.uk. The prescribed forms regulations were updated for the post-1 May 2026 grounds, so check the current version before serving rather than relying on a saved older copy. The prescribed wording must be followed precisely. The notice must specify Ground 1A as the ground relied upon, give the earliest date after which possession proceedings can be issued (4 months from the date of service for Ground 1A) and be signed and dated by the landlord or the landlord's agent.
Evidence to gather BEFORE serving
Ground 1A requires genuine intent to sell. If the tenant contests possession, the court will look for evidence that the landlord actually intends to sell rather than using the ground speculatively. Have at least two of the following in place before service:
- A current valuation from an estate agent or RICS surveyor
- A signed estate agency agreement or instruction letter (post-notice marketing is also fine, but having an agent lined up is good evidence)
- Solicitor correspondence on the planned sale
- An indicative offer from a specialist cash buyer (if going that route)
This evidence does not need to be filed with the notice. It needs to exist, be dated and be available if the tenant later asks for proof or a court does.
Service
Service can be in person, by recorded delivery or in line with any service-of-notices clause in the tenancy agreement. In person is the cleanest: the landlord (or their agent) hands the notice to the tenant on a doorstep visit, asks the tenant to acknowledge receipt and keeps a dated copy. Recorded delivery is a workable alternative; track-and-trace receipts are valid proof. Email-only service is risky unless the tenancy agreement specifically permits it.
The 4-month clock
The 4-month period runs from the date of service. If service is on 10 May, the earliest date for possession proceedings is 10 September of the same year. The tenant is entitled to remain until that date.
The no-relet restricted period
This is the part many landlords miss. Under the Renters' Rights Act 2025, the landlord cannot market or offer the property for letting or a licence to occupy (e.g. Airbnb) for a restricted period starting from the date the notice is served, and ending 12 months after the date the notice period expires and the earliest date proceedings for possession will begin, or 12 months from the issue of any particulars of claim for a possession claim. In practical terms, allowing for the 4-month notice period, a landlord is forbidden from re-letting the property for a minimum 16 months from the date the notice is served.
Listing the property as "to let" on Rightmove, Zoopla or any other portal during this period is an offence with civil penalties up to £7,000 for a first offence and up to £40,000 for repeat or serious cases. There is a narrow "all reasonable steps" defence and limited exceptions, both of which are best assumed not to apply unless a solicitor confirms otherwise.
Logging service properly
Keep a dated copy of the served notice, proof of service (signed acknowledgement, recorded-delivery slip, witness note), and a contemporaneous note of the conversation if the notice was handed over in person. This pack stays with the file from now until at least 12 months after completion.
If the Tenant Does Not Leave: Court Possession
Most tenants leave during the 4-month notice period; many of those who do not vacate by the end of the notice still leave shortly afterwards once they see the landlord intends to follow through. A small minority stay and require a court possession order. Here is what that involves.
Filing the claim
Once the 4-month notice has expired and the tenant is still in occupation, the landlord (or solicitor) files a possession claim at the county court. The claim references Ground 1A as a mandatory ground, attaches the original notice and proof of service, and pays the court fee.
Hearing date
County court possession timetables in 2026 vary by region; 8 to 16 weeks from filing to hearing is realistic. Some regions are quicker, some slower. The hearing itself is usually short for an undefended claim and longer where the tenant disputes the ground or raises a defence.
The order
If the court is satisfied that Ground 1A is made out, it grants a possession order specifying a date by which the tenant must leave (typically 14 days, sometimes longer in cases of exceptional hardship). The order is sealed and sent to both parties; the timetable adds another 2 to 4 weeks to the process.
Bailiff stage
If the tenant still does not leave by the date in the possession order, the landlord applies for a warrant of possession and a county court bailiff attends to enforce it. Bailiff appointments add further weeks (in some regions, months) on top.
Realistic total timeline
For a fully contested case from notice service to bailiff-enforced possession: 7 to 9 months. For a notice period followed by a court order with the tenant leaving voluntarily before bailiff: 5 to 6 months. For a tenant who leaves during the notice period (the most common outcome): 4 months exactly.
None of this delay can be avoided by serving notice early in the tenancy. The notice cannot expire before the tenancy has been running 12 months, which means the earliest a Ground 1A notice can be served is 8 months into the tenancy (an 8-month service plus the 4-month notice expires at month 12).
The Selling-Tenanted Process
If the route is to sell with the tenant in place, the marketing process runs in parallel with the continuing tenancy. There is no notice, no possession claim, no waiting period; the seller goes to market when the agent is ready and the buyer steps into the landlord's shoes on completion.
Briefing the agent
Tell the agent up front that the property is tenanted. The marketing language, the photography approach and the listing description all change for a tenanted lot. The valuation will also change: comparable evidence for tenanted sales sits below comparable evidence for vacant sales of equivalent flats, and a good agent will explain the gap clearly. Some agents specialise in investor-led tenanted sales; if your flat is in an area with active landlord buyers, a specialist agent often outperforms a generalist on price.
The photographer and the listing
The tenant has to allow access for the photographer. Most tenants agree once asked politely. Photography is usually one or two visits of an hour or so. The listing is then created with the property described as tenanted, the rent and the deposit-protection scheme noted, and the marketing aimed squarely at investor buyers.
Viewings
This is where tenanted sales differ from vacant sales. The tenant has to allow buyers in for viewings, and the agent has to schedule around the tenant's preferences. Best practice:
- Agree a small number of viewing windows in advance (one evening, one weekend morning) rather than ad hoc
- Always give the tenant at least 24 hours notice (longer is better)
- Keep the visits brief: 15 to 20 minutes
- Have the agent attend with the buyer; the tenant should not be expected to manage the visit
A tenant who is treated well at this stage is more likely to allow second viewings, surveys and any pre-completion access the buyer's solicitor wants.
Buyer enquiries about the tenant
The buyer's solicitor will want to see the tenancy agreement, the deposit protection certificate, current gas and electrical safety certificates, the EPC, any property licence (if the property is in a selective licensing area) and rent payment history for the previous 6 to 12 months. Have these to hand before listing.
Assignment of the AST on completion
On completion, the tenancy is formally assigned to the buyer by deed. The tenant is told who the new landlord is (a legal duty under section 3 of the Landlord and Tenant Act 1985), the deposit is moved between deposit protection schemes (DPS, MyDeposits or TDS) into the new landlord's account, and from completion onwards the buyer collects the rent.
The Direct Cash-Buyer Route (and Why It Still Needs Ground 1A)
Many specialist cash buyers (including Sell Flat UK) buy with vacant possession only. Some companies do advertise that they buy tenanted properties, but practice varies and a small number drop the offer or insist on vacant possession at the conveyancing stage; our mistakes to avoid when selling to a quick-sale company guide covers the questions worth asking before committing. For sellers using a cash buyer that buys vacant only, a tenanted-flat seller does not skip the Ground 1A step; they move it to the front of the process.
How the route actually works
The sequence is:
- Get an indicative offer from the cash buyer based on the property as it would be sold vacant. This is free and quick (a phone call plus a desk valuation, sometimes a viewing).
- If the figures work, serve a Section 8 notice with Ground 1A and start the 4-month clock.
- Marketing pause (optional). The cash buyer's offer is usually held open for the duration of the notice period; some sellers like to test the open market in parallel.
- When vacant possession is obtained (either the tenant leaves voluntarily during the notice or a court order follows), confirm completion with the cash buyer.
- Cash-buyer completion is fast once vacant: 2 to 4 weeks is typical, sometimes faster.
Realistic timeline
Total: 5 to 6 months from the date the Section 8 notice is served to cash in the seller's account. Most of that is the 4-month notice period, which cannot be shortened. The cash-buyer side is the fast bit at the end.
The trade-off
The cash-buyer route on a tenanted flat trades the open-market risk (chains, lender delays, fall-throughs) for the time and cost of the Ground 1A process and the no-relet restricted period that runs to 12 months after the notice expires. For a seller with a difficult tenant, an unmortgageable building or a tight deadline once vacant, this trade-off often makes sense. For a seller with a happy long-term tenant in a saleable building, the conventional sell-tenanted route to another landlord usually nets a better result.
Worth getting an indicative offer from a cash buyer before serving notice, even if you end up going the open-market route once vacant: knowing the worst-case net figure gives the seller a clearer view of the overall decision.
Completion-Specific Steps on a Tenanted Sale
Completion mechanics for a tenanted sale differ slightly from a vacant sale at a few specific points.
Sold tenanted (with the tenant in place)
- Deposit transfer. The deposit moves from the seller's deposit protection scheme account to the buyer's, on the same scheme or a different one. The tenant gets fresh certificates from the new landlord.
- AST assignment. The tenancy is formally assigned by deed (handled by the two solicitors as part of the conveyancing pack).
- Section 3 LTA 1985 notice. The buyer (the new landlord) must give the tenant their name and contact address within 2 months of taking over. Most buyers' solicitors handle this as part of the post-completion paperwork.
- Keys. Keys go to the new landlord, not the tenant; the tenant keeps the set they already have.
- Rent apportionment. Rent paid for the part of the month before completion goes to the seller, the part after goes to the buyer. Handled on the completion statement.
Sold with vacant possession (Ground 1A route)
- Tenant has already left. By completion the property is empty and standard completion mechanics apply (see our completion day guide).
- Final rent and deposit. The deposit is returned to the tenant after their departure (less any deductions for damage or unpaid rent), in line with the deposit protection scheme rules.
- Final utility readings and council tax notification. Done either by the tenant on the last day or by the landlord shortly after.
- Empty period. Between the tenant leaving and completion, the landlord pays council tax on the empty property at the rate set by the local authority (most councils now charge full rate or higher on empty properties, with limited or no exemption windows) and continues to pay service charge and ground rent.
Both routes
Notification to the managing agent and freeholder of the new ownership; service charge and ground rent apportioned at completion as for any leasehold sale; Notice of Transfer served on the freeholder by the buyer's solicitor in line with the lease.
Common Process Pitfalls
The same handful of issues come up across most tenanted sales. They are all avoidable with awareness.
- Serving Ground 1A so the notice expires too early. The notice cannot expire before the tenancy has been running 12 months. The earliest a Ground 1A notice can be served is 8 months into the tenancy (the 4-month notice then expires at month 12). A notice served earlier expires too early and is invalid.
- Speculative Ground 1A. Serving a Ground 1A notice without genuine intent to sell. Courts can refuse the possession order if the tenant raises and proves a lack of genuine intent. Local-authority enforcement under the Renters' Rights Act adds a further layer of risk.
- Forgetting the no-relet restricted period when a sale falls through. The period runs from the date the Section 8 notice was served until 12 months after the notice expires (so roughly 16 months in total for a standard 4-month Ground 1A notice). If the sale falls through during that window, the property cannot be relet until the period ends. Listing on Rightmove as "to let" inside that window is itself an offence.
- Tenant arrears emerging during conveyancing. A tenanted sale shows the buyer the rent payment history. Arrears that surface mid-conveyancing can prompt the buyer to renegotiate or pull out.
- Deposit not properly re-protected post-completion. The new landlord must register the deposit in their own name within 30 days of completion. Failure exposes the buyer to penalties, but the seller often gets dragged into the dispute too.
- Freeholder consent never obtained for the original AST. Some leases require freeholder consent to let the flat in the first place. If consent was not obtained when the tenancy started, that defect persists into the sale and the buyer's solicitor will raise it. The usual fixes are retroactive consent (sometimes with a fee), a deed of variation or indemnity insurance.
- Block insurance not declared as tenanted. Some block-policy insurers require notification of tenanted occupation and may exclude or limit cover for an undeclared tenancy. A claim during the tenant's stay could be rejected if the policy condition was breached.
- Pending Section 20 major works during the tenancy. Scaffolding, water shutoffs and restricted access during major works can affect the tenant's quiet enjoyment and prompt complaints or refusals to allow viewings. The buyer will want to know about any pending works; the tenant should be told if anything affects their use of the flat. A tenanted sale where major works are about to start often gets renegotiated mid-conveyancing.
- Forgetting the tenant's right to quiet enjoyment during marketing. Pushing too hard on viewings can prompt a complaint to the local authority or a small-claims action. The pace of viewings on a tenanted lot is necessarily slower than on an empty one.
Relevant Legislation
Five pieces of law sit behind the practical decisions on this page. The deeper legal background is in our topic guide on selling a flat with a tenant; what follows is a brief reference.
The Renters' Rights Act 2025 abolished Section 21 (no-fault eviction) on 1 May 2026, made all assured shorthold tenancies periodic from that date, introduced Ground 1A (Sale of Property) and Ground 1 (Owner-occupier) as mandatory grounds for possession, and created the 12-month no-relet restriction that runs from the date a Ground 1A or Ground 1 notice is served. Most of the Act is now in force; sections 43-49 are still pending commencement under SI 2026/6.
The Housing Act 1988 (as amended) sets out the underlying assured tenancy framework. Schedule 2 contains the grounds for possession (now amended by the Renters' Rights Act 2025) and section 8 sets out the notice procedure. The prescribed Section 8 notice form is given under regulations made under this Act, updated for the post-1 May 2026 grounds.
The Landlord and Tenant Act 1985, section 3 requires the new landlord (the buyer on a tenanted sale) to give their name and contact address to the tenant in writing, within 2 months of taking over. Failure is a criminal offence. The seller's solicitor usually flags this for the buyer's solicitor on completion.
The Tenant Fees Act 2019 (as amended by the Renters' Rights Act 2025) caps and restricts what landlords and agents can charge tenants in connection with a tenancy. Sale-related work falls outside the list of permitted payments, so a tenant cannot be billed for the landlord's sale process. The tenant's deposit moves between deposit protection schemes at no cost to the tenant under the schemes' own rules.
The lease itself is the final piece. Many leasehold flat leases require freeholder consent for the flat to be let in the first place; some require notification of any AST registration. Where a tenanted sale is contemplated, the lease's assignment provisions and any AST clauses need to be reviewed with the seller's solicitor.
The Leasehold and Freehold Reform Act 2024 is a parallel reform programme; its provisions affect lease extensions and freeholder relationships but do not change tenanted-sale mechanics. Some provisions are commenced; most are still phasing in.

Frequently Asked Questions
The Section 8 notice uses a prescribed form, available from gov.uk. The prescribed forms regulations were updated for the post-1 May 2026 grounds, so use the current version rather than a saved older copy, and follow the prescribed wording precisely. The notice has to specify Ground 1A as the ground relied upon, give the earliest date after which possession proceedings can begin (4 months from the date of service for Ground 1A) and be signed and dated by the landlord or the landlord's agent. Service can be in person, by recorded delivery or in line with any service-of-notices clause in the tenancy agreement. Keep a dated copy of the notice and clear proof of service. Even where a landlord is comfortable serving the notice themselves, a 30-minute conversation with a solicitor before service is often money well spent.
A landlord can serve a Section 8 notice without a solicitor. The form is prescribed and the wording is set out, so the mechanics themselves are straightforward. A solicitor is genuinely useful where the tenancy agreement has unusual service-of-notices wording, where the tenant is likely to contest possession, or where the landlord wants advice on the evidence to gather in support of Ground 1A if the case goes to court. For most straightforward cases the landlord serves the notice themselves and only involves a solicitor if the tenant has not left by the end of the 4-month period and possession proceedings are needed.
The tenant has a right to quiet enjoyment of their home, which means they can refuse access for viewings. Most tenancy agreements include a clause giving the landlord reasonable access for repairs and inspections, but sale viewings are a different matter and many tenancy agreements do not specifically cover them. The practical approach is to ask early, give plenty of notice, schedule around the tenant's work and keep visits brief. Some tenants are happy to help; others find viewings intrusive. If the tenant simply will not allow viewings, the landlord cannot force the issue, and the answer is usually to switch to selling tenanted (no viewings of an empty interior needed) or to wait for vacant possession before marketing.
The deposit must be kept in one of the three approved deposit protection schemes (DPS, MyDeposits, TDS) throughout the tenancy. When the property is sold with the tenant in place, the deposit transfers to the new landlord as part of the sale. The transfer is handled through the deposit protection scheme: the seller informs the scheme that the property has been sold and a new landlord is taking over, and the scheme moves the protection to the new landlord's account. The buyer's solicitor will normally want evidence that the deposit is properly protected before completion. The seller should not return the deposit to the tenant on sale; the tenancy continues and the deposit continues to be held against the same tenancy.
Some companies advertise that they buy tenanted properties; others (including Sell Flat UK) buy with vacant possession only. Where a cash buyer does claim to buy tenanted, do thorough checks first: a small but real number advertise tenanted purchases and then drop out at conveyancing or insist on vacant possession after all. Our mistakes to avoid when selling to a quick-sale company guide covers the questions worth asking. For sellers using a cash buyer that buys with vacant possession only, the route is to first serve a Section 8 notice citing Ground 1A, wait the 4 months, obtain vacant possession (either by the tenant leaving voluntarily or via a court possession order) and only then complete. Total realistic timeline: 5 to 6 months from notice to completion. Worth getting an indicative offer from the cash buyer before serving the notice, so the figures are clear before committing to selling.
A tenant is free to leave before the notice expires; the 4-month period is a minimum the landlord must wait, not a minimum the tenant must serve. Where a tenant agrees to leave early (perhaps because they have found a new place) the landlord can complete a sale earlier. What the landlord cannot do is shortcut the no-relet restricted period by accepting an early departure. That period runs from the date the Section 8 notice was served through to 12 months after the notice expires (about 16 months in total for a standard 4-month Ground 1A notice), regardless of when the tenant actually leaves. So if the tenant agrees to leave a month after the notice and the landlord then sells, the restricted period still has roughly 15 months to run; if the sale falls through, the property cannot be relet during that window.
County court timetables in 2026 vary by region, but a contested Ground 1A possession claim typically takes 8 to 16 weeks from filing to a hearing, plus 2 to 4 weeks for the order to be perfected, plus bailiff time if the tenant still does not leave. Realistic total timeline from the date the Section 8 notice is served to bailiff-enforced possession in a fully contested case: 7 to 9 months. Most cases do not go this far; many tenants leave during the 4-month notice period and many of those who stay vacate after the possession order is granted but before the bailiff is needed.
A landlord who has been marketing tenanted can pause, serve Ground 1A and re-market with vacant possession after the notice expires. The sequence works: marketing tenanted, no buyer or unhappy with offers, withdraw from market, serve Ground 1A, wait 4 months, tenant leaves or court order, re-market vacant. The no-relet restricted period starts on the date the Section 8 notice is served and runs for 12 months after the notice expires (about 16 months in total), so once you serve, you are committed to selling for the duration of that period. Switching the other way (started Ground 1A, then decided to sell tenanted instead) is harder, because the no-relet rule still applies once notice has been served, and a tenanted re-let to a new tenant would breach it.
Strictly, no. There is no statutory duty to tell a tenant the landlord is marketing the property. But hiding it is rarely a good idea. The estate agent will need access for the photographer, then for viewings, then for buyer visits; the tenant will know almost immediately. A landlord who tells the tenant up front, explains the timeline and treats them respectfully through the process is much more likely to keep them on side. A tenant who finds out via a Rightmove listing is much more likely to refuse access, contest a possession claim and become difficult to deal with at every subsequent stage.
The full paper trail makes any later dispute easier to handle. Keep: the original tenancy agreement and any variations; deposit protection scheme certificates; current gas safety, EICR and EPC certificates; rent payment history; correspondence with the tenant about the sale (including notes from the conversation when you first told them); the dated Section 8 notice and proof of service; valuations, agent listing instructions and solicitor correspondence supporting genuine intent to sell (relevant if Ground 1A is later challenged); and the completion statement once the sale finishes. A simple physical or digital folder with these in it will see the seller through any challenge from the tenant or any local-authority enquiry under the Renters' Rights Act enforcement provisions.
