25 HELENA ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The four 25 HELENA ROAD sales between May 1995 and February 2005 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 May 2002 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the February 2005 sale, where it falls to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might 25 HELENA ROAD be worth now?

25 HELENA ROAD might now be worth an estimated £505,810.

This is based on house price inflation of 119.9%, between February 2005 and July 2025, for semi-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 119.9% inflationary increase is applied to the most recent sale price for 25 HELENA ROAD of £230,000 on 17th February 2005. For the value to have increased from £230,000 to £505,810 over the nineteen years and seven months to July 2025, the following assumptions must hold true:

• The value of 25 HELENA ROAD has moved in line with the HPI for semi-detached houses in the Windsor and Maidenhead local authority area.
• The February 2005 sale price of £230,000 represented a fair market value for the property.
