25 SLADE ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The three 25 SLADE ROAD sales between October 1999 and December 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 April 2002 sale was for 31% below the HPI. So the extrapolation line tracks at 31% below the HPI over time, until the December 2025 sale, where it falls to 34% below the HPI. The line then continues to track at 34% below the HPI.

What might 25 SLADE ROAD be worth now?

This is based on house price deflation of 2.2%, between December 2025 and May 2026, for detached houses, in the Vale of Glamorgan local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 2.2% deflationary decrease is applied to the most recent sale price for 25 SLADE ROAD of £350,000 on 2nd December 2025. For the value to have decreased from £350,000 to £342,125 over the one year and seven months to May 2026, the following assumptions must hold true:
