Land registry data shows two sales for TY CEILIOG since 1st January 1995. The below table shows the price paid for the two sales, along with the average detached price in the Vale of Glamorgan local authority area for the corresponding sale date. One of the two TY CEILIOG sales was for above 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 |
|---|---|---|---|
2013 31 JAN | £385,000 | £293,920 | 31% above HPI |
1999 8 JAN | £65,000 | £115,936 | 44% below HPI |
The below graph shows the average detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The two TY CEILIOG sales from January 1999 and January 2013 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 January 1999 sale was for 44% below the HPI. So the extrapolation line tracks at 44% below the HPI over time, until the January 2013 sale, where it rises to 31% above the HPI. The line then continues to track at 31% above the HPI.

TY CEILIOG might now be worth an estimated £706,080.
This is based on house price inflation of 83.4%, between January 2013 and July 2026, for detached houses, in the Vale of Glamorgan local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 83.4% inflationary increase is applied to the most recent sale price for TY CEILIOG of £385,000 on 31st January 2013. For the value to have increased from £385,000 to £706,080 over the twelve years and six months to July 2026, the following assumptions must hold true:
