BRON EIRIAN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Gwynedd local authority area over time, sourced from the HPI. The three BRON EIRIAN sales between June 2000 and December 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 2021 sale was for 43% above the HPI. So the extrapolation line tracks at 43% above the HPI over time, until the December 2025 sale, where it falls to 39% above the HPI. The line then continues to track at 39% above the HPI.

What might BRON EIRIAN be worth now?

BRON EIRIAN might now be worth an estimated £426,362.

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

The 1.5% inflationary increase is applied to the most recent sale price for BRON EIRIAN of £420,000 on 5th December 2025. For the value to have increased from £420,000 to £426,362 over the one year and eight months to April 2026, the following assumptions must hold true:

• The value of BRON EIRIAN has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The December 2025 sale price of £420,000 represented a fair market value for the property.
• The size, condition, and specification of BRON EIRIAN has not materially changed since December 2025.
