These are completed sales recorded by HM Land Registry, not asking prices, from the UK House Price Index for the Royal Borough of Windsor and Maidenhead. The borough is a unitary authority, so one figure covers Windsor, Maidenhead, Ascot, Eton, Datchet, Old Windsor, Cookham, Bray, Sunningdale, Sunninghill, Wraysbury and the Walthams.

Twelve months took £23,577 off the average borough home. The single month to July 2026 was down 0.9 per cent as well. July 2025 was the most expensive month in the borough’s record, so the annual fall and the fall from the all-time peak are the same number. The borough is falling while England as a whole rises 1.1 per cent. See what the July figures mean in detail.

The Royal Borough is one of a small number of English districts where the average detached house is still above £1.1 million. It is also one where the semi-detached average, £602,082, sits above the all-property average, because the borough has enough flats to drag the middle down.

Every category is falling. Flats fell hardest, down 6.2 per cent, which is £20,092 off the average and the 18th steepest fall in flat prices of the 295 English districts. Detached houses are down 3.6 per cent, or £41,775. Terraced homes fell 3.1 per cent and semis 2.7 per cent.

A first-time buyer in the borough paid an average of £427,828 in July 2026, which is 4.2 per cent less than a year earlier. A home mover, someone selling one property to buy another, paid £715,724, down 3.7 per cent.

The £287,896 between those two is the real cost of the step from a first flat to a family house here. Buyers paying cash averaged £591,050 and buyers with a mortgage £570,549, a gap of only £20,501, which is unusually narrow for an expensive district.

What actually sold, street by street

The index is a modelled average. The raw record is more useful when you are trying to price a specific house, so we pulled every completed sale HM Land Registry has recorded in the borough for the year to 30 June 2026: 1,683 sales.

The median was £520,000. The mean was £747,995. That £227,995 gap is almost entirely Ascot, where a handful of sales in the SL5 0 sector run into the millions and pull the average up without telling you anything about a normal house.

Post townSalesMedian
Ascot (SL5)213£650,000
Maidenhead (SL6)870£501,250
Windsor (SL4)470£500,000

Windsor and Maidenhead are within £1,250 of each other on the median. That surprises people who assume the castle carries a premium over the town up the road, and it does not, at least not at the middle of the market. Ascot is £150,000 clear of both.

By postcode sector

The spread inside the borough is far wider than the spread between its two main towns.

The gap between the dearest sector and the cheapest is £369,500, on a borough whose two ends are eleven miles apart. SL6 1, the Maidenhead town centre postcode where most of the new flats have gone up, is the cheapest place to buy in the borough by some distance. SL4 3, Dedworth, is the cheapest part of Windsor.

Windsor beats Maidenhead on semis and terraces; Maidenhead beats Windsor on detached houses, because its detached stock is concentrated in Pinkneys Green, Cookham and the rural west rather than the town. Ascot flats cost £100,000 more than Windsor flats.

New builds sold at a median of £642,500 across the borough, against £520,000 for existing homes, but on only 34 recorded sales in the year, so treat that as a description of what was being built rather than a premium you can rely on.

England£293,479+1.1%

Windsor and Maidenhead is the most expensive district in Berkshire, £78,499 above Wokingham and £239,277 above Slough next door, and it costs nearly twice the England average. It is not, however, growing. Buckinghamshire over the river is adding 1.1 per cent a year while this borough sheds 3.9 per cent, and Slough has closed the gap by £17,255 in twelve months. Five of Berkshire’s six unitary authorities fell in the year to July 2026; only West Berkshire rose.

What holds the premium up is a short list: the castle and the Great Park, the Green Belt that covers most of the borough and stops the towns joining up, two rail routes into London, and school catchments people move for. What is capping it is the same thing capping the rest of the outer Thames Valley, which is that at £575,036 the mortgage arithmetic only works for a narrow slice of buyers.
