Land registry data shows two sales for 21 WOOLWICH ROAD since 1st January 1995. The below table shows the price paid for the two sales, along with the average semi-detached price in the Bexley local authority area for the corresponding sale date. One of the two 21 WOOLWICH ROAD sales was roughly equal to the average price, whilst the other was 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 |
|---|---|---|---|
2002 29 NOV | £187,500 | £187,707 | Close to HPI |

The below graph shows the average semi-detached house price in the Bexley local authority area over time, sourced from the HPI. The two 21 WOOLWICH ROAD sales from April 2001 and November 2002 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 April 2001 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the November 2002 sale, where it rises to roughly the same level as the HPI. The line then continues to track in line with the HPI.

21 WOOLWICH ROAD might now be worth an estimated £527,055.
This is based on house price inflation of 181.1%, between November 2002 and May 2026, for semi-detached houses, in the Bexley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 181.1% inflationary increase is applied to the most recent sale price for 21 WOOLWICH ROAD of £187,500 on 29th November 2002. For the value to have increased from £187,500 to £527,055 over the 24 years and six months to May 2026, the following assumptions must hold true:
