The Price Gap Between Flats and Houses Is the Widest on Record
New Zoopla data shows houses now cost more relative to flats than at any point in its index. Here is what is behind the gap, and what it means if you are selling a leasehold flat.
The Gap at a Glance
The gap between what a house costs and what a flat costs has never been wider. According to Zoopla's latest house price index, reported by The Negotiator, the average house in Britain is now worth around 1.7 times the average flat: the largest difference in the roughly 30 years Zoopla's index has tracked. The average flat sits at about £193,000, against roughly £327,000 for the average house.
What Zoopla Found
Strip out London, where flats make up a bigger share of the market, and the gap is wider still, at about 2.3 times. It reaches around 2.5 times in the West Midlands, and even in London houses cost about 1.9 times the price of a flat. Richard Donnell, Zoopla's executive director, put it plainly: "The gap between house and flat prices has never been wider."
The headline figure is the cumulative effect of nearly a decade of flats lagging behind. Zoopla's numbers show house prices up about 43 percent since 2016, while flat prices rose just 10 percent over the same period, well behind inflation. In real terms, the average flat has gone backwards.
How the Gap Opened Up
The causes are well rehearsed, and we have covered them in detail before. The pandemic "race for space" pushed buyers towards houses with gardens. The building-safety and cladding crisis, and the EWS1 checks that came with it, froze parts of the flat market for years. Service charges have climbed sharply. Short leases and the long wait for leasehold reform have made buyers more cautious. And the steady retreat of buy-to-let investors, after a series of tax changes, removed a big chunk of the demand that used to support flat prices.
Our article on why UK flat prices are falling behind house prices works through each of these in turn, and why service charges are increasing for leasehold flats covers one of the running costs that puts buyers off.
- Lease length and the years remaining
- Ground rent and service charge levels
- EWS1 and building-safety paperwork
- The managing agent and the state of the block
- Fewer lenders will lend on some flats
- Usually freehold, so no lease to run down
- No ground rent and no service charge
- No shared building-safety checks
- You decide on repairs and alterations
- A wider pool of mortgage lenders
A Note of Perspective
A record gap makes for a striking headline, but it is worth keeping in proportion. These are national averages, and the flat market is not one thing. A long-lease flat in a well-run block with a clean fire-safety position behaves very differently from a short-lease flat in a building waiting on cladding remediation. The "widest on record" claim refers to Zoopla's own index rather than all of property history, and the gap varies enormously by region and by building.
There is another side to it, too. A wider gap is the same thing as flats being relatively cheaper, which is why first-time buyers priced out of houses keep turning to them as the affordable way in. And if the outstanding parts of the Leasehold and Freehold Reform Act 2024 are brought into force, some of the leasehold risk that has weighed on flat values could ease, though slowly rather than overnight. None of this is a reason to panic, and it is certainly not a reason to sell in a hurry.
What It Means If You Are Selling a Flat
The data is a backdrop, not a verdict on your own flat. What actually decides your sale is how your specific flat compares with others on the local market, and how cleanly it gets through conveyancing. A few practical points.
Worth doing
- Get the paperwork ready before you list: the lease and the years remaining, the fire-safety position, the last few years of service charge accounts and the management pack. Most flat sales that fall through, fall through on these, and having them ready removes the friction that drags flat prices down.
- Price to the local flat market as it is today, not to house-price headlines or what the flat "should" be worth. Overpricing and then chasing the market down is how sellers end up making a loss.
- Be realistic about the bigger-ticket problems. A short lease or outstanding cladding work is expensive to put right, so weigh what the fix would cost against the discount a buyer will want for taking it on. If the issue rules out mainstream lenders, a cash buyer may be the surer route to completion, at a price that reflects it.
Worth avoiding
- Do not rely on an online valuation alone. Automated estimates lean on broad averages and nearby sales, so they miss what really sets a flat's price: the lease length, the service charge, the floor and the condition of the block. Two flats in the same building can sell for very different sums, so get a proper read from an agent or a buyer who has actually seen your flat.
- Do not keep a known problem quiet. A short lease, a cladding issue or a steep service charge will surface in the legal pack, and it has to be disclosed as material information anyway. Hiding it does not avoid the discount; it just means the sale is more likely to fall through later, once a buyer's solicitor uncovers the problem and weeks have already been wasted.
- Do not over-spend on cosmetics when the real blockers are leasehold or lender issues. A new kitchen rarely fixes a mortgage problem.
The wider picture is hard to ignore, and for some flats the leasehold and building-safety drag is not going away quickly. But a well-presented, fairly-priced flat with clean paperwork and a long lease still sells, even in a market where the gap to houses has never been bigger.
