THAMESIDE 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 THAMESIDE sales from October 2010 and January 2021 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 2010 sale was for 103% above the HPI. So the extrapolation line tracks at 103% above the HPI over time, until the January 2021 sale, where it rises to 204% above the HPI. The line then continues to track at 204% above the HPI.

What might THAMESIDE be worth now?

THAMESIDE might now be worth an estimated £3,445,873.

This is based on house price inflation of 16.8%, between January 2021 and July 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 16.8% inflationary increase is applied to the most recent sale price for THAMESIDE of £2,950,000 on 12th January 2021. For the value to have increased from £2,950,000 to £3,445,873 over the three years and six months to July 2025, the following assumptions must hold true:

  • The value of THAMESIDE has moved in line with the HPI for detached houses in the Windsor and Maidenhead local authority area.
  • The January 2021 sale price of £2,950,000 represented a fair market value for the property.
  • The size, condition, and specification of THAMESIDE has not materially changed since January 2021.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
