16A HEOL Y PLAS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Carmarthenshire local authority area over time, sourced from the HPI. The two 16A HEOL Y PLAS sales from February 2020 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 2020 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the August 2025 sale, where it rises to 40% above the HPI. The line then continues to track at 40% above the HPI.

What might 16A HEOL Y PLAS be worth now?

16A HEOL Y PLAS might now be worth an estimated £391,455.

This is based on house price inflation of 3%, between August 2025 and May 2026, for detached houses, in the Carmarthenshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3% inflationary increase is applied to the most recent sale price for 16A HEOL Y PLAS of £380,000 on 15th August 2025. For the value to have increased from £380,000 to £391,455 over the one year and three months to May 2026, the following assumptions must hold true:

• The value of 16A HEOL Y PLAS has moved in line with the HPI for detached houses in the Carmarthenshire local authority area.
• The August 2025 sale price of £380,000 represented a fair market value for the property.
