CAE BACH is a very large extended detached house of 182m², built sometime between 1983 and 1990, which could now be worth an estimated £454,130. It was last sold for £227,500 in December 2003, which was around 49% above the average December 2003 detached price in the Pembrokeshire local authority area. The most recent EPC inspection was August 2025, where the current energy rating was B, and the potential energy rating was B.
Land registry data shows two sales for CAE BACH since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Pembrokeshire local authority area for the corresponding sale date. Both of the two CAE BACH 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 |
|---|---|---|---|
2003 3 DEC | £227,500 | £152,389 | 49% above HPI |
1999 1 JUL | £99,000 | £69,972 | 41% above HPI |
The below graph shows the average detached house price in the Pembrokeshire local authority area over time, sourced from the HPI. The two CAE BACH sales from July 1999 and December 2003 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 1999 sale was for 41% above the HPI. So the extrapolation line tracks at 41% above the HPI over time, until the December 2003 sale, where it rises to 49% above the HPI. The line then continues to track at 49% above the HPI.

CAE BACH might now be worth an estimated £454,130.
This is based on house price inflation of 99.6%, between December 2003 and July 2026, for detached houses, in the Pembrokeshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 99.6% inflationary increase is applied to the most recent sale price for CAE BACH of £227,500 on 3rd December 2003. For the value to have increased from £227,500 to £454,130 over the 23 years and five months to July 2026, the following assumptions must hold true:
