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.
CLAMBERDOWN is a midsized extended detached house of 148m², built sometime between 1983 and 1990, which could now be worth an estimated £666,681. It was last sold for £444,000 in January 2014, which was around 58% above the average January 2014 detached price in the Cornwall local authority area. The most recent EPC inspection was March 2015, where the current energy rating was B, and the potential energy rating was A.
Land registry data shows two sales for CLAMBERDOWN since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Cornwall local authority area for the corresponding sale date. Both of the two CLAMBERDOWN 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 |
|---|---|---|---|
2014 13 JAN | £444,000 | £280,880 | 58% above HPI |
2005 26 MAY | £390,000 | £261,384 | 49% above HPI |
The below graph shows the average detached house price in the Cornwall local authority area over time, sourced from the HPI. The two CLAMBERDOWN sales from May 2005 and January 2014 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 2005 sale was for 49% above the HPI. So the extrapolation line tracks at 49% above the HPI over time, until the January 2014 sale, where it rises to 58% above the HPI. The line then continues to track at 58% above the HPI.

CLAMBERDOWN might now be worth an estimated £666,681.
This is based on house price inflation of 50.2%, between January 2014 and July 2026, for detached houses, in the Cornwall local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 50.2% inflationary increase is applied to the most recent sale price for CLAMBERDOWN of £444,000 on 13th January 2014. For the value to have increased from £444,000 to £666,681 over the eleven years and six months to July 2026, the following assumptions must hold true:
