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.
THE FIRS is a large detached house of 143m², built sometime between 1983 and 1990, which could now be worth an estimated £308,453. It was last sold for £210,000 in April 2016, which was around 5% below the average April 2016 detached price in the Powys local authority area. The most recent EPC inspection was December 2015, where the current energy rating was E, and the potential energy rating was C.
Land registry data shows two sales for THE FIRS since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Powys local authority area for the corresponding sale date. One of the two THE FIRS sales was for below the average price, whilst the other was 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 |
---|---|---|---|
2016 20 APR | £210,000 | £220,387 | ![]() 5% below HPI |
1996 31 MAY | £83,500 | £69,483 | ![]() 20% above HPI |
The below graph shows the average detached house price in the Powys local authority area over time, sourced from the HPI. The two THE FIRS sales from May 1996 and April 2016 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 May 1996 sale was for 20% above the HPI. So the extrapolation line tracks at 20% above the HPI over time, until the April 2016 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.
THE FIRS might now be worth an estimated £308,453.
This is based on house price inflation of 46.9%, between April 2016 and February 2025, for detached houses, in the Powys local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 46.9% inflationary increase is applied to the most recent sale price for THE FIRS of £210,000 on 20th April 2016. For the value to have increased from £210,000 to £308,453 over the nine years and two months to February 2025, the following assumptions must hold true:

The plot extent is a Land Registry INSPIRE Index Polygon, and it is important to note that a title may include more than one polygon, whereas only one polygon is shown on the map (the polygon which intersects with the position of THE FIRS). The full extent of the land contained in any registered title can only be identified from the individual title plan. The maps on this page should not be relied upon to establish the extent of a title.
