CORNWALL is a large extended detached house of 132m², built sometime before 1900, which could now be worth an estimated £398,130. It was last sold for £300,000 in January 2019, which was around 29% above the average January 2019 detached price in the Gwynedd local authority area. The most recent EPC inspection was December 2016, where the current energy rating was E, and the potential energy rating was B.
Land registry data shows three sales for CORNWALL since 1st January 1995. The below table shows the price paid for the three sales, along with the average detached price in the Gwynedd local authority area for the corresponding sale date. All of the three CORNWALL sales were for above the average price. The average price is sourced from the Office for National Statistics' House Price Index (HPI).
Date | Price | HPI Price | Variation from HPI |
---|---|---|---|
2019 17 JAN | £300,000 | £233,270 | ![]() 29% above HPI |
2003 23 JUN | £280,000 | £127,529 | ![]() 120% above HPI |

The below graph shows the average detached house price in the Gwynedd local authority area over time, sourced from the HPI. The three CORNWALL sales between August 2000 and January 2019 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 June 2003 sale was for 120% above the HPI. So the extrapolation line tracks at 120% above the HPI over time, until the January 2019 sale, where it falls to 29% above the HPI. The line then continues to track at 29% above the HPI.
CORNWALL might now be worth an estimated £398,130.
This is based on house price inflation of 32.7%, between January 2019 and June 2025, 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 32.7% inflationary increase is applied to the most recent sale price for CORNWALL of £300,000 on 17th January 2019. For the value to have increased from £300,000 to £398,130 over the five years and seven months to June 2025, the following assumptions must hold true:
