The below graph shows the average semi-detached house price in the Bromley local authority area over time, sourced from the HPI. The four 40 HEATHFIELD ROAD sales between June 2002 and February 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 2010 sale was for 48% above the HPI. So the extrapolation line tracks at 48% above the HPI over time, until the February 2025 sale, where it falls to 10% above the HPI. The line then continues to track at 10% above the HPI.

40 HEATHFIELD ROAD might now be worth an estimated £737,683.
This is based on house price inflation of 5.4%, between February 2025 and October 2025, for semi-detached houses, in the Bromley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 5.4% inflationary increase is applied to the most recent sale price for 40 HEATHFIELD ROAD of £699,970 on 20th February 2025. For the value to have increased from £699,970 to £737,683 over the four months to October 2025, the following assumptions must hold true:
