How Thomas Street, Treharris prices moved
The chart tracks the median Thomas Street, Treharris house price for every year with a recorded sale, from 1999 to 2025. The dashed line restates each year in 2026 money, so the two lines separate exactly as much as inflation has eroded the cash figure.
| Decade | Years with sales | Median paid | In today's money |
|---|---|---|---|
| 1990s | 1 | £28,500 | £63,283 |
| 2010s | 1 | £70,000 | £98,700 |
| 2020s | 1 | £119,950 | £122,558 |
The highest yearly median on record for Thomas Street, Treharris is £119,950 in 2025; the lowest is £28,500 in 1999. Across the full 27-year record the cash median has moved from £28,500 to £119,950.
In 2026 money that first median is worth £58,071, so the real change over the whole record is +111.0% — about +2.91% a year after inflation. Cash growth and real growth are not the same story, and the gap is the part most price reports leave out.
Over the last decade alone the difference is stark: +71.4% in cash against +22.1% once inflation is removed. A buyer who sold at the end of that decade would have needed the real figure, not the headline one, to know whether they had actually gained.

Ownership and new build in Thomas Street, Treharris
0 of the sales on record are leasehold and 65 freehold — 0.0% of the market. Tenure is not a detail: a leasehold flat and a freehold house are different assets, and mixing them into one median hides the difference.

|---|---|---|---|
| Leasehold | 0 | 0.0% | — |
| Freehold | 65 | 100.0% | £67,000 |
A further 2 transfers for this area are on the register but are left out of every figure above. HM Land Registry marks them as additional price paid entries: repossessions, buy-to-let portfolio moves, transfers between companies or family, and sales at a discount such as right to buy. They are real records but they are not open-market prices, and including them would drag the median somewhere no buyer ever paid.
Section 09
