17 SUMNER PLACE 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 two 17 SUMNER PLACE sales from April 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 April 2006 sale was for 35% above the HPI. So the extrapolation line tracks at 35% above the HPI over time, until the July 2025 sale, where it falls to 29% above the HPI. The line then continues to track at 29% above the HPI.

What might 17 SUMNER PLACE be worth now?

17 SUMNER PLACE might now be worth an estimated £638,342.

This is based on house price inflation of 3.5%, between July 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 3.5% inflationary increase is applied to the most recent sale price for 17 SUMNER PLACE of £617,000 on 31st July 2025. For the value to have increased from £617,000 to £638,342 over the one year and two months to May 2026, the following assumptions must hold true:

• The value of 17 SUMNER PLACE has moved in line with the HPI for semi-detached houses in the Runnymede local authority area.
