76 COG 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 76 COG ROAD sales between March 2003 and March 2026 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 July 2018 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the March 2026 sale, where it rises to 18% above the HPI. The line then continues to track at 18% above the HPI.

What might 76 COG ROAD be worth now?

This is based on house price inflation of 2.3%, between March 2026 and April 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 2.3% inflationary increase is applied to the most recent sale price for 76 COG ROAD of £600,000 on 13th March 2026. For the value to have increased from £600,000 to £613,825 over the eleven months to April 2026, the following assumptions must hold true:
