The below graph shows the average semi-detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The four 10 LLYS DWYNWEN sales between May 1996 and November 2022 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 March 2016 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the November 2022 sale, where it rises to 7% below the HPI. The line then continues to track at 7% below the HPI.

10 LLYS DWYNWEN might now be worth an estimated £281,189.
This is based on house price inflation of 0.4%, between November 2022 and August 2025, for semi-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 0.4% inflationary increase is applied to the most recent sale price for 10 LLYS DWYNWEN of £280,000 on 18th November 2022. For the value to have increased from £280,000 to £281,189 over the three years and three months to August 2025, the following assumptions must hold true:
