21 MAPLE CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Caerphilly local authority area over time, sourced from the HPI. The two 21 MAPLE CLOSE sales from November 2024 and November 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 November 2024 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the November 2025 sale, where it rises to 44% above the HPI. The line then continues to track at 44% above the HPI.

What might 21 MAPLE CLOSE be worth now?

21 MAPLE CLOSE might now be worth an estimated £294,143.

This is based on house price inflation of 5.1%, between November 2025 and April 2026, for semi-detached houses, in the Caerphilly local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 5.1% inflationary increase is applied to the most recent sale price for 21 MAPLE CLOSE of £280,000 on 14th November 2025. For the value to have increased from £280,000 to £294,143 over the one year and seven months to April 2026, the following assumptions must hold true:

• The value of 21 MAPLE CLOSE has moved in line with the HPI for semi-detached houses in the Caerphilly local authority area.
• The November 2025 sale price of £280,000 represented a fair market value for the property.
