1 BOSTON GROVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hillingdon local authority area over time, sourced from the HPI. The two 1 BOSTON GROVE sales from October 2021 and September 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 October 2021 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the September 2025 sale, where it rises to 37% above the HPI. The line then continues to track at 37% above the HPI.

What might 1 BOSTON GROVE be worth now?

1 BOSTON GROVE might now be worth an estimated £1,274,682.

This is based on house price deflation of 1.9%, between September 2025 and May 2026, for detached houses, in the Hillingdon local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.9% deflationary decrease is applied to the most recent sale price for 1 BOSTON GROVE of £1,300,000 on 19th September 2025. For the value to have decreased from £1,300,000 to £1,274,682 over the one year and four months to May 2026, the following assumptions must hold true:
