HARPSCOT Price Paid vs. HPI Average

The below graph shows the average detached house price in the Mid Sussex local authority area over time, sourced from the HPI. The three HARPSCOT sales between October 2012 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 August 2019 sale was for 38% above the HPI. So the extrapolation line tracks at 38% above the HPI over time, until the August 2025 sale, where it rises to 51% above the HPI. The line then continues to track at 51% above the HPI.

What might HARPSCOT be worth now?

HARPSCOT might now be worth an estimated £1,107,879.

This is based on house price deflation of 1.5%, between August 2025 and May 2026, for detached houses, in the Mid Sussex local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.5% deflationary decrease is applied to the most recent sale price for HARPSCOT of £1,125,000 on 6th August 2025. For the value to have decreased from £1,125,000 to £1,107,879 over the one year and three months to May 2026, the following assumptions must hold true:

• The value of HARPSCOT has moved in line with the HPI for detached houses in the Mid Sussex local authority area.
• The August 2025 sale price of £1,125,000 represented a fair market value for the property.
• The size, condition, and specification of HARPSCOT has not materially changed since August 2025.
