Land registry data shows two sales for 15 BRYN SIRIOL since 1st January 1995. The below table shows the price paid for the two sales, along with the average semi-detached price in the Flintshire local authority area for the corresponding sale date. Both of the two 15 BRYN SIRIOL 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 |
|---|---|---|---|
2000 30 JUN | £46,000 | £49,160 | 6% below HPI |
1998 20 APR | £35,500 | £43,507 | 18% below HPI |
The below graph shows the average semi-detached house price in the Flintshire local authority area over time, sourced from the HPI. The two 15 BRYN SIRIOL sales from April 1998 and June 2000 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 1998 sale was for 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the June 2000 sale, where it rises to 6% below the HPI. The line then continues to track at 6% below the HPI.

15 BRYN SIRIOL might now be worth an estimated £178,621.
This is based on house price inflation of 288.3%, between June 2000 and May 2026, for semi-detached houses, in the Flintshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 288.3% inflationary increase is applied to the most recent sale price for 15 BRYN SIRIOL of £46,000 on 30th June 2000. For the value to have increased from £46,000 to £178,621 over the 26 years and one month to May 2026, the following assumptions must hold true:
