How Percy Road, Isleworth prices moved
The chart tracks the median Percy Road, Isleworth house price for every year with a recorded sale, from 1997 to 2021. The dashed line restates each year in 2026 money, so the two lines separate exactly as much as inflation has eroded the cash figure.
| Decade | Years with sales | Median paid | In today's money |
|---|---|---|---|
| 1990s | 1 | £117,475 | £260,850 |
| 2000s | 2 | £272,000 | £495,504 |
| 2010s | 1 | £625,000 | £881,250 |
| 2020s | 1 | £750,000 | £766,304 |
The highest yearly median on record for Percy Road, Isleworth is £750,000 in 2021; the lowest is £117,475 in 1997. Across the full 25-year record the cash median has moved from £117,475 to £750,000.
In 2026 money that first median is worth £249,082, so the real change over the whole record is +280.4% — about +5.73% 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: +120.5% in cash against +66.0% 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.

The most recent sales
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.

What sells here
The mix of property types explains a large part of any area's median. Percy Road, Isleworth is dominated by the type at the top of this table, so its overall median leans that way.
| Property type | Sales | Share | Median paid | Range |
|---|---|---|---|---|
| Terraced | 67 | 75.3% | £399,999 | £35,910 – £895,000 |
| Semi-detached | 22 | 24.7% | £284,950 | £48,000 – £825,000 |
Section 06
Ownership and new build in Percy Road, Isleworth
0 of the sales on record are leasehold and 89 freehold — 0.0% 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.
| Category | Sales | Share | Median paid |
|---|---|---|---|
| Leasehold | 0 | 0.0% | — |
| Freehold | 89 | 100.0% | £375,000 |
A further 2 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.

Every certificate carries an energy efficiency band as well as a floor area. Across Hounslow, 52.2% of 121,020 certificates sit in bands A to C, and 2.3% in F or G — the bands that cost the most to heat and are hardest to mortgage.
| Energy band | Certificates | Share |

The Office for National Statistics puts the mean private rent in Hounslow at £1,941 a month as of Jun 2026 — £1,574 for a one-bedroom home and £2,228 for three bedrooms.
Against the median sale of £375,000 here, that rent is a gross yield of 6.21% a year. It is a measured figure rather than an assumption: a real local rent over a real local price, before any cost of ownership.
Police forces publish every recorded street-level crime. Within a mile of the centre of TW7, 466 crimes were recorded in Jun 2026: 198 violent, 12 burglary, 29 vehicle-related and 98 anti-social behaviour. The median postcode district in this archive recorded 167 in the same month, so this one is 2.8 times busier.
Against the 288,181 residents the 2021 census counted in Hounslow, that is 1.62 recorded crimes per thousand people in the month. The count covers a mile around the district centre while the population covers the whole council, so read the rate as an order of magnitude rather than a precise figure.
A count is not a rate. A district with shops and a station records more crime than a residential one of the same size, because more people pass through it. Read this next to the median, not on its own.

Within Isleworth the street ranks 42 of 249 by median price, and its median is above the town figure of £250,000 (+50.0%).

Percy Road, Isleworth sits in Hounslow, in London.
The Office for National Statistics puts the median home in Hounslow at 11.3 times median local earnings of £43,068 a year, measured to Sep 2025. Across England and Wales the same ratio is 7.6. That number, not the price alone, is what decides whether a place is within reach of the people who work in it.

Quick answers
Common questions about this data
What is the average house price in Percy Road, Isleworth?
The median price paid in Percy Road, Isleworth across every sale on the register is £375,000. 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 Percy Road, Isleworth?
89 sales are on record for Percy Road, Isleworth, the most recent completing on 11 Jul 2025. Every one is a completed transfer lodged with HM Land Registry, not an asking price or an estimate.
Have Percy Road, Isleworth house prices actually risen?
In cash, the median rose +120.5% between 2008 and 2021. In 2026 money — that is, after inflation — the change is +66.0%. Both numbers are true; only the second one tells you whether buying here preserved value.
When were Percy Road, Isleworth house prices at their highest?
The highest yearly median on record is £750,000, set in 2021. 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 Percy Road, Isleworth?
£4,206 per square metre, from the 12 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 Jul 2025. 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.
