A locality in Caernarfon.
Sold house prices in Deiniolen have an overall average of £137,988, based on all 143 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 Deiniolen, the median sold price over the 12 months to July 2026 was £130,000 — it rose 9.2% on the year before. That reflects 19 recorded sales. Detached homes are the priciest at a median of £307,500, while terraced homes are the most affordable at £119,000. Over the past year, other homes moved the most (+121.1%).
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 |
|---|---|---|---|
| Terraced | £119,000 | -5.9% | 13 |
| Detached | £307,500 | -22.6% | 2 |
| Other | £210,000 | +121.1% | 2 |
| Semi-detached | £127,000 | +12.9% | 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.
