COPPERTOPS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The two COPPERTOPS sales from October 1998 and November 2006 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 1998 sale was for 46% below the HPI. So the extrapolation line tracks at 46% below the HPI over time, until the November 2006 sale, where it rises to 41% below the HPI. The line then continues to track at 41% below the HPI.

What might COPPERTOPS be worth now?

COPPERTOPS might now be worth an estimated £665,773.

This is based on house price inflation of 98.7%, between November 2006 and June 2025, for detached houses, in the Windsor and Maidenhead local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 98.7% inflationary increase is applied to the most recent sale price for COPPERTOPS of £335,000 on 3rd November 2006. For the value to have increased from £335,000 to £665,773 over the nineteen years and five months to June 2025, the following assumptions must hold true:

• The value of COPPERTOPS has moved in line with the HPI for detached houses in the Windsor and Maidenhead local authority area.
• The November 2006 sale price of £335,000 represented a fair market value for the property.
• The size, condition, and specification of COPPERTOPS has not materially changed since November 2006.
