7 ONSLOW WAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Elmbridge local authority area over time, sourced from the HPI. The two 7 ONSLOW WAY sales from January 2016 and October 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 January 2016 sale was for 35% below the HPI. So the extrapolation line tracks at 35% below the HPI over time, until the October 2025 sale, where it rises to 26% below the HPI. The line then continues to track at 26% below the HPI.

What might 7 ONSLOW WAY be worth now?

This is based on house price inflation of 2.2%, between October 2025 and May 2026, for detached houses, in the Elmbridge local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.2% inflationary increase is applied to the most recent sale price for 7 ONSLOW WAY of £1,142,500 on 8th October 2025. For the value to have increased from £1,142,500 to £1,167,646 over the one year and five months to May 2026, the following assumptions must hold true:
