166 WINDSOR ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Swindon local authority area over time, sourced from the HPI. The two 166 WINDSOR ROAD sales from December 2005 and September 2025 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 December 2005 sale was for 52% above the HPI. So the extrapolation line tracks at 52% above the HPI over time, until the September 2025 sale, where it rises to 56% above the HPI. The line then continues to track at 56% above the HPI.

What might 166 WINDSOR ROAD be worth now?

This is based on house price inflation of 2.9%, between September 2025 and May 2026, for semi-detached houses, in the Swindon local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.9% inflationary increase is applied to the most recent sale price for 166 WINDSOR ROAD of £440,000 on 5th September 2025. For the value to have increased from £440,000 to £452,835 over the one year and four months to May 2026, the following assumptions must hold true:
