The most recent EPC inspection was June 2013, where the current energy rating was E, and the potential energy rating was B.
Land registry data shows three sales for BRYN GWYN since 1st January 1995. The below table shows the price paid for the three sales, along with the average detached price in the Isle of Anglesey local authority area for the corresponding sale date. All of the three BRYN GWYN sales were for below 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 |
|---|---|---|---|
2015 13 MAR | £123,000 | £202,412 | 39% below HPI |
2014 13 MAR | £120,000 | £197,368 | 39% below HPI |
2004 9 SEP | £130,000 | £181,198 | 28% below HPI |
The below graph shows the average detached house price in the Isle of Anglesey local authority area over time, sourced from the HPI. The three BRYN GWYN sales between September 2004 and March 2015 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 March 2014 sale was for 39% below the HPI. So the extrapolation line tracks at 39% below the HPI over time, until the March 2015 sale, which was also at 39% below the HPI.

BRYN GWYN might now be worth an estimated £198,662.
This is based on house price inflation of 61.5%, between March 2015 and May 2026, for detached houses, in the Isle of Anglesey local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 61.5% inflationary increase is applied to the most recent sale price for BRYN GWYN of £123,000 on 13th March 2015. For the value to have increased from £123,000 to £198,662 over the ten years and ten months to May 2026, the following assumptions must hold true:
