The below graph shows the average semi-detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The four 1 WELHAM MANOR sales between March 1995 and November 2021 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 July 2011 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the November 2021 sale, where it rises to 37% above the HPI. The line then continues to track at 37% above the HPI.
1 WELHAM MANOR might now be worth an estimated £697,365.
This is based on house price inflation of 1.8%, between November 2021 and July 2025, for semi-detached houses, in the Welwyn Hatfield local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 1.8% inflationary increase is applied to the most recent sale price for 1 WELHAM MANOR of £685,000 on 29th November 2021. For the value to have increased from £685,000 to £697,365 over the four years and four months to July 2025, the following assumptions must hold true:
