The headline for 2025 is easy to write: London's median sale price came in at £507,000, barely changed from £510,000 the year before. Flat. Quiet. Not much to see here.
That reading is wrong. Beneath the aggregate number sit four distinct stories — none of which the median tells on its own.
A market still finding its footing
London recorded 87,589 completed sales in 2025, the lowest annual volume since at least 2018, excluding the COVID-affected 2020. The post-rate-rise slowdown that started in 2023 has not reversed. Buyers are still cautious, chains are still slow, and transaction count is the clearest signal of underlying confidence.
| Year | Transactions | Median price |
|---|---|---|
| 2021 | 143,371 | £492,500 |
| 2022 | 122,585 | £513,825 |
| 2023 | 96,088 | £510,000 |
| 2024 | 105,244 | £510,000 |
| 2025 | 87,589 | £507,000 |

Volume in 2025 was 39% below the 2021 peak. The brief recovery in 2024 has reversed. For sellers, this matters more than the median: in a thin market, properties take longer to find buyers and price discovery is noisier.
Going back five years, the nominal five-year gain is roughly 5.5% — just over 1% per year. Well below inflation over the same period. In real terms, London buyers have been paying more pounds for less purchasing power.
Outer and inner London are not the same market
The flat aggregate conceals a sharp geographic split. Outer and outer-south London boroughs have been quietly rising. Prime central London has been correcting — and not modestly.
Boroughs with the largest gains (2024 → 2025):
| Borough | 2024 median | 2025 median | Change |
|---|---|---|---|
| Bromley | £480,000 | £510,000 | +6.2% |
| Waltham Forest | £500,000 | £525,000 | +5.0% |
| Havering | £430,000 | £450,000 | +4.7% |
| Hillingdon | £480,000 | £500,000 | +4.2% |
| Barking & Dagenham | £360,000 | £375,000 | +4.2% |
Boroughs with the sharpest falls (2024 → 2025):
| Borough | 2024 median | 2025 median | Change |
|---|---|---|---|
| Hammersmith & Fulham | £775,000 | £667,000 | −13.9% |
| City of London | £920,000 | £796,250 | −13.5% |
| Kensington & Chelsea | £1,200,000 | £1,050,000 | −12.5% |
| City of Westminster | £960,000 | £850,000 | −11.5% |
| Camden | £790,000 | £740,000 | −6.3% |
Kensington & Chelsea dropped £150,000 in median terms in a single year. Bromley rose £30,000. These are not minor fluctuations around a common trend — they represent structurally different dynamics playing out simultaneously within the same city boundary.
The pattern is consistent with what has been visible since 2022: buyers priced out of inner London have shifted demand to well-connected outer boroughs with good schools and faster commutes. Meanwhile, the top end of the market is facing a combination of higher borrowing costs, stamp duty drag at high values,¹ and continued softness in international demand for trophy assets.
The two-speed split is not a blip. It has been building for three years. The 2025 data is its clearest expression yet.
Buying a flat in London has been a losing trade
The property type split over five years is unambiguous — and consequential for anyone making a buying decision today.
| Year | Flats | Terraced houses |
|---|---|---|
| 2020 | £435,500 | £500,000 |
| 2021 | £424,235 | £530,000 |
| 2022 | £439,000 | £580,000 |
| 2023 | £435,000 | £563,000 |
| 2024 | £432,000 | £565,000 |
| 2025 | £420,000 | £562,500 |
Flat prices have fallen over five years — from £435,500 in 2020 to £420,000 in 2025, a drop of 3.6% in nominal terms, and considerably worse in real terms once inflation is accounted for.
Terraced houses went in the other direction: from £500,000 in 2020 to £562,500 in 2025, a gain of 12.5% in nominal terms. Semi-detached (£615,000) and detached (£865,000) are up similarly.
The gap between flats and houses has widened significantly since 2020. There is no single cause. Service charge uncertainty, ongoing cladding remediation costs,² the long tail of leasehold reform anxiety,³ and changing preferences for outdoor space since the pandemic are all plausible contributors. What is clear is that the flat market and the house market are no longer moving together — and have not been for several years.
For a buyer choosing between a flat and a terraced house at similar price points, the five-year return differential is roughly 16 percentage points in nominal terms. That is the cost of compromising on property type.
The new-build premium has vanished
For most of the past decade, new-build properties in London commanded a meaningful premium over resale — typically 20–30%.⁴ In 2025, that premium has essentially disappeared.
| Type | 2025 median | Transactions |
|---|---|---|
| New build | £505,000 | 2,941 |
| Resale | £507,500 | 84,648 |
New builds sold for a median of £505,000 — fractionally below the resale median of £507,500. New builds represent just 3.4% of total transactions, so the sample is relatively thin and a single development skewing the mix can move the number. But the historical premium that used to be the default assumption for off-plan buyers has clearly compressed.
Developer incentives partly explain this: stamp duty contributions and furniture packages reduce the effective cost to the buyer without reducing the registered completion price.⁵ There is also a timing effect: many 2025 completions were contracted in 2022–2023, when developers were pricing more aggressively to shift units in a slowing market.
For buyers, the practical implication is that the traditional objection to new-build — paying over the odds — is weaker than it was three years ago. Whether that reflects genuine value or a market in distress is a question each buyer has to answer for their specific development.
What the numbers add up to
Four distinct findings from one year of official data:
-
Transaction volume is still depressed. The market is not frozen, but it is thin. Sellers who need to move are making concessions they would not have made in 2021.
-
The geographic split is widening. Outer London boroughs — Bromley, Waltham Forest, Havering — are performing like a different asset class from Kensington, Westminster, and the City.
-
Flats have underperformed houses for five consecutive years. The structural reasons show no sign of reversing quickly.
-
New-build pricing has reset. The premium that once made off-plan buying feel expensive is gone, at least for now.
None of this is visible in the headline median. That number — £507,000, fractionally below £510,000 — is accurate as a summary statistic and nearly useless as a guide to any specific decision. The London property market is not one market. It never was. But in 2025, the divergence between its parts is wider than it has been in years.
Notes & sources
¹ Stamp duty at high values. The additional SDLT surcharge for properties above £1.5M has been in place since 2014 and was further tightened in the 2022 Autumn Statement. HMRC SDLT statistics confirm declining transaction volumes in the £1M+ band from 2022 onwards. Source: Stamp duties statistics — GOV.UK.
² Cladding remediation. The Building Safety Act 2022 placed legal responsibility for remediation of unsafe cladding on developers and freeholders of buildings over 11 metres. Leaseholders in affected blocks face ongoing uncertainty over service charge costs and mortgage eligibility, even where the developer levy covers structural works. Source: Building Safety Act 2022, HM Government.
³ Leasehold reform anxiety. The Leasehold and Freehold Reform Act 2024 passed in May 2024, restricting new leasehold houses and making lease extension easier — but implementation timelines and ground rent rules remain subject to secondary legislation, leaving buyers uncertain about the future cost of their lease. Source: Leasehold and Freehold Reform Act 2024, HM Government.
⁴ Historical new-build premium of 20–30%. This range is widely cited in residential market research. Nationwide Building Society's house price data and Savills' residential development research both document a consistent new-build premium over equivalent resale properties in London from 2010 to 2021. Sources: Nationwide House Price Index; Savills UK Residential Development research (published annually).
⁵ Developer incentives and registered sale prices. RICS guidance for surveyors (RICS Valuation — Global Standards, UK national supplement) requires that developer incentives such as cashback, stamp duty paid, and furniture packages be disclosed and deducted from the assessed market value, precisely because they do not reduce the price registered at the Land Registry. This gap between registered price and true economic cost is a known limitation of the Land Registry dataset for new-build comparisons. Source: RICS Residential Valuations standards.
