The chart tracks the median SL9 9 house price for every year with a recorded sale, from 1995 to 2026. The dashed line restates each year in 2026 money, so the two lines separate exactly as much as inflation has eroded the cash figure.

The highest yearly median on record for SL9 9 is £710,000 in 2025; the lowest is £122,500 in 1996. Across the full 32-year record the cash median has moved from £123,500 to £672,500.

In 2026 money that first median is worth £274,228, so the real change over the whole record is +145.2% — about +2.94% a year after inflation. Cash growth and real growth are not the same story, and the gap is the part most price reports leave out.

Over the last decade alone the difference is stark: +28.1% in cash against -8.2% once inflation is removed. A buyer who sold at the end of that decade would have needed the real figure, not the headline one, to know whether they had actually gained.

Every row is a completed sale as lodged with HM Land Registry. The right-hand column restates the price in 2026 money, which is the only fair way to compare a sale from the 1990s with one from last year.

These addresses appear in the register more than once, so the same bricks are being priced twice. That makes them the strongest evidence of what actually happened to SL9 9 values — no mix of property types can flatter the number.

The mix of property types explains a large part of any area's median. SL9 9 is dominated by the type at the top of this table, so its overall median leans that way.

Energy Performance Certificates record a floor area for every home that has been surveyed, sold or let — far more homes than have changed hands. 694 certificates cover SL9 9, and their median floor area is 83 m².

The median across the whole register is 76 m², so homes here are larger than average — +9.2%. Size explains a large part of why one area's median price sits above another's, which is why the price per square metre further up this page is the fairer comparison.

565 of the sales on record are leasehold and 2,647 freehold — 17.6% of the market. Tenure is not a detail: a leasehold flat and a freehold house are different assets, and mixing them into one median hides the difference.

The median leasehold sale is £225,000 and the median freehold sale £390,000 — a gap of +73.3%. Most of that gap is property type rather than tenure itself: leasehold here is largely flats, freehold largely houses.

New builds sold for more than the median existing home — +16.5%. A new-build premium is normal: the buyer gets a warranty and nothing to fix, and the price is set by a developer rather than negotiated between two households.

A further 147 transfers for this area are on the register but are left out of every figure above. HM Land Registry marks them as additional price paid entries: repossessions, buy-to-let portfolio moves, transfers between companies or family, and sales at a discount such as right to buy. They are real records but they are not open-market prices, and including them would drag the median somewhere no buyer ever paid.

The median across the whole archive is £157,500. SL9 9 sits above that national figure — +123.8%.

Where an EPC floor area could be matched to the sale, the median works out at £3,706 per square metre, across 60 of the 3,212 sales on record. Price per square metre is the only figure that compares a two-bed flat with a four-bed house honestly.

The full range on record runs from £29,500 to £2,830,358. Extremes usually mean something unusual — a plot sold without a house on it, a transfer between family members, or a very large property — so the median is the number to trust.

What is the average house price in SL9 9?

The median price paid in SL9 9 across every sale on the register is £352,475. The median is used rather than the mean because a handful of very large sales would otherwise drag the average away from what a typical buyer paid.

How many homes have sold in SL9 9?

3,212 sales are on record for SL9 9, the most recent completing on 11 Jun 2026. Every one is a completed transfer lodged with HM Land Registry, not an asking price or an estimate.

Have SL9 9 house prices actually risen?

In cash, the median rose +28.1% between 2016 and 2026. In 2026 money — that is, after inflation — the change is -8.2%. Both numbers are true; only the second one tells you whether buying here preserved value.

When were SL9 9 house prices at their highest?

The highest yearly median on record is £710,000, set in 2025. That is the cash figure; measured in 2026 money the peak may fall in a different year, because inflation reshapes the series.

What is the price per square metre in SL9 9?

£3,706 per square metre, from the 60 sales where an EPC floor area could be matched to the address. Price per square metre strips out size, so a flat and a house can be compared on the same basis.

How current is this data?

The latest sale shown here completed on 11 Jun 2026. HM Land Registry publishes Price Paid Data monthly and a sale can take a month or two to appear after completion, so the most recent weeks are always incomplete.
