CRANTOCK is a very large extended detached house of 193m², built sometime between 1983 and 1990, which could now be worth an estimated £283,466. It was last sold for £275,000 in July 2025, which was around 21% below the average July 2025 detached price in the Northumberland local authority area. The most recent EPC inspection was February 2025, where the current energy rating was D, and the potential energy rating was C.
Land registry data shows three sales for CRANTOCK since 1st January 1995. The below table shows the price paid for the three sales, along with the average detached price in the Northumberland local authority area for the corresponding sale date. All of the three CRANTOCK 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 |
|---|---|---|---|
2025 28 JUL | £275,000 | £348,918 | 21% below HPI |
2018 17 SEP | £135,000 | £273,265 | 51% below HPI |
1999 22 JAN | £35,000 | £94,162 | 63% below HPI |
The below graph shows the average detached house price in the Northumberland local authority area over time, sourced from the HPI. The three CRANTOCK sales between January 1999 and July 2025 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 2018 sale was for 51% below the HPI. So the extrapolation line tracks at 51% below the HPI over time, until the July 2025 sale, where it rises to 21% below the HPI. The line then continues to track at 21% below the HPI.

CRANTOCK might now be worth an estimated £283,466.
This is based on house price inflation of 3.1%, between July 2025 and April 2026, for detached houses, in the Northumberland local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 3.1% inflationary increase is applied to the most recent sale price for CRANTOCK of £275,000 on 28th July 2025. For the value to have increased from £275,000 to £283,466 over the one year and three months to April 2026, the following assumptions must hold true:
