18 DERWENT CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Runnymede local authority area over time, sourced from the HPI. The three 18 DERWENT CLOSE sales between November 2010 and November 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 July 2017 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the November 2025 sale, where it falls to 19% below the HPI. The line then continues to track at 19% below the HPI.

What might 18 DERWENT CLOSE be worth now?

18 DERWENT CLOSE might now be worth an estimated £399,615.

This is based on house price inflation of 1.2%, between November 2025 and May 2026, for semi-detached houses, in the Runnymede local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.2% inflationary increase is applied to the most recent sale price for 18 DERWENT CLOSE of £395,000 on 11th November 2025. For the value to have increased from £395,000 to £399,615 over the one year and six months to May 2026, the following assumptions must hold true:

• The value of 18 DERWENT CLOSE has moved in line with the HPI for semi-detached houses in the Runnymede local authority area.
• The November 2025 sale price of £395,000 represented a fair market value for the property.
