ERISKAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Torfaen local authority area over time, sourced from the HPI. The four ERISKAY sales between March 2008 and August 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 2022 sale was for 52% above the HPI. So the extrapolation line tracks at 52% above the HPI over time, until the August 2025 sale, where it falls to 49% above the HPI. The line then continues to track at 49% above the HPI.

What might ERISKAY be worth now?

ERISKAY might now be worth an estimated £506,106.

This is based on house price inflation of 1.2%, between August 2025 and April 2026, for detached houses, in the Torfaen local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.2% inflationary increase is applied to the most recent sale price for ERISKAY of £500,000 on 11th August 2025. For the value to have increased from £500,000 to £506,106 over the one year and four months to April 2026, the following assumptions must hold true:

• The value of ERISKAY has moved in line with the HPI for detached houses in the Torfaen local authority area.
• The August 2025 sale price of £500,000 represented a fair market value for the property.
• The size, condition, and specification of ERISKAY has not materially changed since August 2025.
