| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|

The below graph shows the average semi-detached house price in the Hillingdon local authority area over time, sourced from the HPI. The two 129 CLYFFORD ROAD sales from November 1996 and April 2004 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 November 1996 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the April 2004 sale, where it falls to 6% below the HPI. The line then continues to track at 6% below the HPI.

129 CLYFFORD ROAD might now be worth an estimated £543,827.
This is based on house price inflation of 136.4%, between April 2004 and May 2026, 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 136.4% inflationary increase is applied to the most recent sale price for 129 CLYFFORD ROAD of £230,000 on 26th April 2004. For the value to have increased from £230,000 to £543,827 over the 21 years and eleven months to May 2026, the following assumptions must hold true:
