9A THE GROVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The three 9A THE GROVE sales between September 1995 and October 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 February 2012 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the October 2025 sale, where it rises to 32% below the HPI. The line then continues to track at 32% below the HPI.

What might 9A THE GROVE be worth now?

9A THE GROVE might now be worth an estimated £353,675.

This is based on house price inflation of 1%, between October 2025 and May 2026, for detached houses, in the Cardiff local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1% inflationary increase is applied to the most recent sale price for 9A THE GROVE of £350,000 on 31st October 2025. For the value to have increased from £350,000 to £353,675 over the one year and five months to May 2026, the following assumptions must hold true:

• The value of 9A THE GROVE has moved in line with the HPI for detached houses in the Cardiff local authority area.
• The October 2025 sale price of £350,000 represented a fair market value for the property.
• The size, condition, and specification of 9A THE GROVE has not materially changed since October 2025.
