1 WINDMILL CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The two 1 WINDMILL CLOSE sales from May 2006 and July 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the May 2006 sale was for 43% below the HPI. So the extrapolation line tracks at 43% below the HPI over time, until the July 2025 sale, where it rises to 6% below the HPI. The line then continues to track at 6% below the HPI.

What might 1 WINDMILL CLOSE be worth now?

This is based on house price deflation of 5.2%, between July 2025 and April 2026, for detached houses, in the Windsor and Maidenhead local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 5.2% deflationary decrease is applied to the most recent sale price for 1 WINDMILL CLOSE of £1,090,000 on 1st July 2025. For the value to have decreased from £1,090,000 to £1,033,794 over the one year and three months to April 2026, the following assumptions must hold true:
