Windsor Property Market: House Prices, Sold Data & Development Finance, Q3 2026 Review

Windsor: Royal town with ultra-premium values and heritage conversion opportunities near the Castle.

The Windsor property market recorded 556 residential sales in the 12 months to 30 June 2026, with a median sale price of £495,000. This places Windsor £93k above the Berkshire county median of £402,500, and £210k above the approximate UK median of £285,000.

Prices in Windsor have been broadly stable, a year-on-year change of -1%. Within Berkshire, Windsor ranks 2nd by price out of 8 principal towns, and 7th by transaction volume.

On a quarterly view, Windsor median prices moved from £490,000 in Q1 2025 to £499,950 in Q2 2026, a change of +2.0% over 5 quarters.

Windsor & Maidenhead, the local planning authority covering Windsor, approved 18 residential planning applications and refused 13 in Q3 2026 (1 July to 30 September 2026), with 55 still awaiting a decision. That is an approval rate of 58%. Planning figures come from local planning authority records compiled by Landstack, retrieved on 3 October 2026. Councils and Landstack can take several days to publish decisions, so decisions made in the final days of Q3 2026 may not all be included yet.

Schemes approved in Q3 2026, together with those still awaiting a decision, propose around 879 homes, an estimated £410.3m of development value at local sale prices. Treat the unit total as an upper bound, since an outline permission and its reserved-matters application both count.

Windsor & Maidenhead covers more than one town in Berkshire, so these figures are authority-wide rather than specific to Windsor alone.

HM Land Registry has so far registered 13 new-build sales in Windsor for the past 12 months, 2.3% of registered transactions. New-build sales are typically registered 6 to 18 months after completion, so this understates current delivery and is not a completions figure.
