The information on this page is based on a number of underlying datasets, most of which are updated monthly. We maintain an update schedule which explains which version of each dataset we are currently relying on.
ASHLEIGH is a very large extended detached house of 159m², built sometime between 1950 and 1966, which could now be worth an estimated £414,828. It was last sold for £410,000 in June 2026, which was around 17% below the average June 2026 detached price in the Monmouthshire local authority area. The most recent EPC inspection was January 2026, where the current energy rating was E, and the potential energy rating was D.
Land registry data shows two sales for ASHLEIGH since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Monmouthshire local authority area for the corresponding sale date. Both of the two ASHLEIGH 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 |
|---|---|---|---|
2026 19 JUN | £410,000 | £492,846 | 17% below HPI |
2022 29 JUL | £250,000 | £467,201 | 46% below HPI |
The below graph shows the average detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The two ASHLEIGH sales from July 2022 and June 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 July 2022 sale was for 46% below the HPI. So the extrapolation line tracks at 46% below the HPI over time, until the June 2026 sale, where it rises to 17% below the HPI. The line then continues to track at 17% below the HPI.

ASHLEIGH might now be worth an estimated £414,828.
This is based on house price inflation of 1.2%, between June 2026 and July 2026, for detached houses, in the Monmouthshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 1.2% inflationary increase is applied to the most recent sale price for ASHLEIGH of £410,000 on 19th June 2026. For the value to have increased from £410,000 to £414,828 over the eleven months to July 2026, the following assumptions must hold true:
