A locality in Swansea.
Sold house prices in Pontlliw have an overall average of £210,615, based on all 251 residential sales on record — drawn from every recorded UK house sale.
Medians over the most recent 12 months of all UK property sales (to July 2026). Median is used, not mean — it isn't skewed by the odd very-high sale.
Across Pontlliw, the median sold price over the 12 months to July 2026 was £286,500 — it rose 12.4% on the year before. That reflects 17 recorded sales. Detached homes are the priciest at a median of £303,750, while semi-detached homes are the most affordable at £281,000. Over the past year, terraced homes moved the most (+82%). New-build homes were 0% of recent sales, a share that is steady.
These figures track the median of prices actually paid, not a like-for-like index. A move can reflect a change in what sold — more new homes, or a different mix of house types and sizes — as much as any change in what a given home is worth.
| Type | Median | 12-month change | Sales |
|---|---|---|---|
| Semi-detached | £281,000 | +17.6% | 9 |
| Detached | £303,750 | +0.9% | 6 |
| Terraced | £287,500 | +82% | 2 |
Change compares the median for the last 12 months with the 12 months before.

How these figures are calculated. Year-on-year change compares the median sold price over the most recent 12 months of data with the 12 months before it. We use the median, not the average, so a few unusually high or low sales don't distort it. Because HM Land Registry data lags — sales take time to be registered — the most recent month or two are provisional and tend to revise upward. Figures track the mix of what actually sold, so they are not a like-for-like index. The same method is used across this site, so an area's figure here matches its ranking in investment trends.
