The below graph shows the average semi-detached house price in the Conwy local authority area over time, sourced from the HPI. The two 18 BEVAN AVENUE sales from February 2015 and January 2026 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 2015 sale was for 25% below the HPI. So the extrapolation line tracks at 25% below the HPI over time, until the January 2026 sale, where it rises to 6% above the HPI. The line then continues to track at 6% above the HPI.

18 BEVAN AVENUE might now be worth an estimated £232,421.
This is based on house price inflation of 1.1%, between January 2026 and March 2026, for semi-detached houses, in the Conwy local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 1.1% inflationary increase is applied to the most recent sale price for 18 BEVAN AVENUE of £230,000 on 16th January 2026. For the value to have increased from £230,000 to £232,421 over the ten months to March 2026, the following assumptions must hold true:
