Inner vs Outer London house prices in 2026: a shrinking gap
The typical home in Inner London sold for £595,000 in 2025. In Outer London the figure was £500,000. That is a premium of just £95,000, or 1.19 times — and it is narrower than it was a year earlier, when the same measure stood at 1.26 times.
The mental shorthand — inner London expensive, outer London cheap — still holds at the extremes. But at the level of the typical sale the two halves of the capital are closer than most buyers assume, and over the year to 2025 they moved closer still. This piece sets out the borough-by-borough picture using HM Land Registry Price Paid data, and separates the genuine gap from the headline that gets quoted.
Figures cover standard-price residential sales (detached, semi-detached, terraced and flats) registered with HM Land Registry across the 33 Greater London local authorities in calendar year 2025, medians unless stated. Data fetched 1 July 2026.

Where the "three times" headline comes from
The often-quoted figure that inner London costs three times as much as the outer boroughs is a story about the extremes, not the averages. The dearest borough, Kensington and Chelsea, had a median of £1,150,000; the cheapest, Barking and Dagenham, £380,000. That is a 3.0-times spread from one end of the capital to the other.
That gap is real and large. But it sits between two individual boroughs at opposite corners of London. Compare the two halves at their typical sale and the multiple falls to 1.19 — because the boroughs bunch heavily in the £450,000–£600,000 band, where inner and outer interleave.
The model breaks down in the middle
The neat "inner = dear, outer = cheap" rule fails as soon as you leave the top four boroughs:
- Richmond upon Thames is an Outer London borough, yet its £720,000 median makes it the fifth-dearest borough in the capital — ahead of nine of the 13 inner boroughs, including Hammersmith and Fulham, Wandsworth, Islington and Hackney.
- Greenwich (£460,000) and Lewisham (£475,000) are both inner boroughs, yet they undercut most of outer London's west and south-west — cheaper than Richmond, Barnet, Harrow, Kingston, Brent and a dozen others.
In other words, the Inner/Outer boundary is an administrative line drawn in 1965, not a price contour. A buyer comparing budgets is far better served by the borough figure than by the zone label. Our London-wide average house price guide puts the whole-capital median in context, and the flat-versus-house price gap by borough shows how the property mix pushes the prime-borough numbers around.
Why the gap is closing
Two independent readings of the data point the same way for inner London and diverge slightly for outer London.
Raw medians (HM Land Registry):
| Zone | 2024 median | 2025 median | Year-on-year | 2025 sales |
|---|---|---|---|---|
| Inner London | £617,750 | £595,000 | −3.7% | 30,245 |
| Outer London | £490,000 | £500,000 | +2.0% | 48,631 |
| Inner ÷ Outer | 1.26× | 1.19× | — | — |
Mix-adjusted index (ONS UK House Price Index, year to March 2026):
| Index | Mar 2025 | Mar 2026 | Year-on-year |
|---|---|---|---|
| Inner London | 96.2 | 91.8 | −4.6% |
| Outer London | 98.7 | 97.7 | −1.0% |
| London (all) | 97.0 | 95.0 | −2.1% |
| United Kingdom | 102.7 | 102.8 | +0.1% |
For inner London the two measures agree: the raw median fell 3.7% and the mix-adjusted index fell 4.6% over the year to March 2026. For outer London they diverge — the raw median edged up 2.0% while the index eased 1.0% — so the outer figure is best read as broadly flat and mix-sensitive rather than a clear rise. Either way, inner London softened while outer London held, which is what compressed the ratio from 1.26 to 1.19.
One measurement note: the ONS Inner/Outer London index boundary differs marginally from the statutory borough list used for the price table above (the index groups a couple of boroughs differently), so the two are directional companions, not identical geographies. The direction of travel is consistent across both.
The prime top end is doing most of the work. Inner London's mean sale in 2025 was £842,923 against a median of £595,000 — a gulf that reflects a small number of very high-value Kensington, Westminster and Camden transactions dragging the average up. Outer London's mean (£593,767) is far closer to its median (£500,000). The prime segment is also the part of the market most exposed to higher stamp-duty bands and the additional-property surcharge, which is where recent softness has concentrated.
What the gap costs a buyer
The £95,000 difference between the inner and outer median is not the only thing that changes at completion. Standard Stamp Duty Land Tax rises with price:
| At the median | Standard SDLT (2026) | Effective rate |
|---|---|---|
| Outer London (£500,000) | £15,000 | 3.00% |
| Inner London (£595,000) | £19,750 | 3.32% |
Source: HMRC residential SDLT bands, 2026. So the inner premium carries roughly £4,750 more in stamp duty on top of the higher price. First-time buyers and additional-property purchasers pay different amounts — you can run any price through the stamp duty calculator with the relevant flags set.
On the mortgage side, at a 25% deposit and the Bank of England's latest quoted five-year fixed rate of 4.32% (April 2026), a 25-year repayment loan works out at approximately £2,050 a month at the outer median and about £2,435 at the inner median. That is a rate-and-term illustration only; your actual rate depends on your lender, deposit and circumstances. The mortgage calculator lets you test other deposits and terms.
There is also a well-known twist in the running costs: some of the dearest boroughs to buy in are among the cheapest for council tax. Kensington and Chelsea, Westminster and Wandsworth sit at the bottom of the England Band D table while several cheaper outer boroughs charge more — we unpack that inversion in the cheapest and most expensive council tax areas in England.
See the true cost for a specific street
Zone labels and borough medians are a starting point, not an answer. To see the all-in monthly cost — mortgage, council tax, energy and stamp duty — of the actual homes on a given street, put a postcode into Homecost. Try an inner-prime example around Westminster (SW1A 1AA) or the south bank around Southwark (SE1 9SG), then compare it against an outer borough.
