TERTIUS is a very small detached house of 98m², built sometime between 1967 and 1975, which could now be worth an estimated £350,527. It was last sold for £197,500 in December 2010, which was around 19% below the average December 2010 detached price in the South Norfolk local authority area. The most recent EPC inspection was March 2010, where the current energy rating was E, and the potential energy rating was D.
Land registry data shows three sales for TERTIUS since 1st January 1995. The below table shows the price paid for the three sales, along with the average detached price in the South Norfolk local authority area for the corresponding sale date. All of the three TERTIUS 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 |
|---|---|---|---|
2010 7 DEC | £197,500 | £243,603 | 19% below HPI |
2009 27 JAN | £115,000 | £223,949 | 49% below HPI |
2004 23 DEC | £120,000 | £227,484 | 47% below HPI |
The below graph shows the average detached house price in the South Norfolk local authority area over time, sourced from the HPI. The three TERTIUS sales between December 2004 and December 2010 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 January 2009 sale was for 49% below the HPI. So the extrapolation line tracks at 49% below the HPI over time, until the December 2010 sale, where it rises to 19% below the HPI. The line then continues to track at 19% below the HPI.

TERTIUS might now be worth an estimated £350,527.
This is based on house price inflation of 77.5%, between December 2010 and May 2026, for detached houses, in the South Norfolk local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 77.5% inflationary increase is applied to the most recent sale price for TERTIUS of £197,500 on 7th December 2010. For the value to have increased from £197,500 to £350,527 over the sixteen years and seven months to May 2026, the following assumptions must hold true:
