What a London Flat Cost the Year You Were Born

Picture the same one-bedroom London flat changing hands once a decade. In 1995 it sold for around £67,000. Three decades on it carries a price tag of more than £400,000. The flat has not moved an inch, but the figure it sells for has been rewritten beyond recognition, partly by genuine growth and partly by the slow erosion of what the pound is worth (inflation).

The table below shows what a typical London flat changed hands for at each step, taken from the official Land Registry house price index, alongside what that figure is worth in 2026 money once inflation is stripped out.

A London Flat, Decade by Decade

The Land Registry only began tracking flats as a separate category in 1995, so the table starts there. Each price is the London average for flats and maisonettes in January of that year. The third column restates it in 2026 money, using the Office for National Statistics inflation figures, so the eras can be compared like for like.

The third column is each price restated in today's money, not the 2026 price. So the 2020 figure of about £550,000 is what that year's £431,945 would be worth now, not a valuation that has since dropped to £427,856 in cash. In plain pounds the price barely moved over those years: the fall is in real terms, once inflation is taken into account.

The headline numbers climb steeply, then stall. The story behind that shape is more interesting than the prices themselves.

London Flat Prices, 1995 to 2026

Before the Index: the 1970s and 1980s

HM Land Registry only began reporting flats separately from houses in 1995, so there are no flat-specific figures before then. For the earlier decades there is only an average across London houses and flats combined: roughly £5,300 in 1970, about £25,700 in 1980 and around £85,500 in 1990. A flat would have sat a little below each figure.

The eye-watering jump from £5,300 to £85,500 in twenty years was as much about inflation as about property. That 1970 home, restated in 2026 money, works out at roughly £105,000: a real sum, but a fraction of what the same address commands now. Most of the 1970s "boom" was the pound losing value at double-digit rates, not buyers suddenly paying far more in real terms. The 1990 figure looks high because it sits right at the peak before the early-1990s crash, when London prices fell hard and did not recover their 1989 level until the late 1990s.

The Boom Years: 1995 to 2007

This is the stretch that built the modern reputation of London property. A flat bought for £67,000 in 1995 was worth £216,000 by 2005. Even after adjusting for inflation, the real value rose from about £167,000 to about £419,000 in today's money: it more than doubled in real terms in a single decade.

Cheap credit did much of the lifting. Mortgages were easy to come by, lending standards were loose, and buy-to-let landlords piled into flats as an investment. Right to Buy had already moved hundreds of thousands of former council flats into private hands, feeding a resale market that barely existed a generation earlier. For anyone who bought early and sold late, the maths was extraordinary.

Since 2016: the Market Runs Out of Road

Look again at the bottom of the table. In cash terms a London flat has risen only modestly over the past decade, from £375,000 in 2015 to £428,000 now. Once inflation is taken into account it has gone backwards: that 2015 price is worth about £540,000 in today's money, well above what a flat fetches today. A London flat is worth noticeably less in real terms than it was ten years ago. The table's five-year steps also hide a short-lived peak in between: London flats reached around £468,000 in the middle of 2022 before slipping back, so the owners nursing the clearest losses are those who bought at that high point.

Several forces converged. The 3 percent stamp duty surcharge on additional homes, introduced in 2016, took the heat out of buy-to-let demand. The Grenfell Tower fire in 2017 triggered the cladding and EWS1 crisis, which froze sales in affected blocks for years. Service charges climbed sharply, and after 2020 buyers chased houses with gardens rather than flats in dense urban streets. We covered that divergence in more detail in why UK flat prices are falling behind house prices, and the consequences for sellers in London tops the list of loss-making home sales.

What This Means If You Own a Flat

The long arc still favours anyone who has held a London flat for twenty years or more: the real gains of the boom were large and have not been wiped out. The picture is harder for owners who bought in the late 2010s, when prices were already close to where they sit now. They may find the resale price disappointing once rising service charges and a shorter lease are factored in.

None of this makes a flat unsaleable. Well-kept flats with long leases and clean paperwork still sell on the open market. What has changed is that the easy decade of automatic gains is over, and pricing a flat realistically matters more than it did.
