TOP FLAT is a large extended terraced house of 103m², built sometime between 1900 and 1929, which could now be worth an estimated £343,040. It was last sold for £235,000 in June 2017, which was around 32% above the average June 2017 terraced price in the Cardiff local authority area. The most recent EPC inspection was December 2016, where the current energy rating was F, and the potential energy rating was C.
Land registry data shows two sales for TOP FLAT since 1st January 1995. The below table shows the price paid for the two sales, along with the average terraced price in the Cardiff local authority area for the corresponding sale date. Both of the two TOP FLAT 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 |
|---|---|---|---|
2017 1 JUN | £235,000 | £178,319 | 32% above HPI |
1995 8 SEP | £54,000 | £43,397 | 24% above HPI |
The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two TOP FLAT sales from September 1995 and June 2017 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 September 1995 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the June 2017 sale, where it rises to 32% above the HPI. The line then continues to track at 32% above the HPI.

TOP FLAT might now be worth an estimated £343,040.
This is based on house price inflation of 46%, between June 2017 and April 2026, for terraced houses, in the Cardiff local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 46% inflationary increase is applied to the most recent sale price for TOP FLAT of £235,000 on 1st June 2017. For the value to have increased from £235,000 to £343,040 over the nine years and two months to April 2026, the following assumptions must hold true:

TOP FLAT sits on a plot of roughly 0.036 of an acre, or 144m². The below map shows the location of TOP FLAT, an approximate outline of the building(s), and the indicative extent of the property. 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 TOP FLAT). 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.
