The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 15 LOCKGATE ROAD sales from April 2013 and November 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 April 2013 sale was for 57% above the HPI. So the extrapolation line tracks at 57% above the HPI over time, until the November 2025 sale, where it falls to 19% above the HPI. The line then continues to track at 19% above the HPI.

15 LOCKGATE ROAD might now be worth an estimated £340,565.
This is based on house price inflation of 0.2%, between November 2025 and May 2026, for semi-detached houses, in the West Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
