18 CLAMMAS WAY Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Hillingdon local authority area over time, sourced from the HPI. The five 18 CLAMMAS WAY sales between April 1996 and January 2023 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 February 2007 sale was for 32% above the HPI. So the extrapolation line tracks at 32% above the HPI over time, until the January 2023 sale, where it falls to 2% below the HPI. The line then continues to track at 2% below the HPI.

What might 18 CLAMMAS WAY be worth now?

This is based on house price deflation of 0.9%, between January 2023 and February 2025, for semi-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 0.9% deflationary decrease is applied to the most recent sale price for 18 CLAMMAS WAY of £565,000 on 18th January 2023. For the value to have decreased from £565,000 to £559,857 over the one year and eleven months to February 2025, the following assumptions must hold true:

• The value of 18 CLAMMAS WAY has moved in line with the HPI for semi-detached houses in the Hillingdon local authority area.
• The January 2023 sale price of £565,000 represented a fair market value for the property.
