A locality in Kettering.
Sold house prices in Isham have an overall average of £371,322, based on all 164 residential sales on record — drawn from every recorded UK house sale.
Medians over the most recent 12 months of all UK property sales (to May 2026). Median is used, not mean — it isn't skewed by the odd very-high sale.
Across Isham, the median sold price over the 12 months to May 2026 was £287,500 — it fell 32% on the year before. That reflects 14 recorded sales. Other homes are the priciest at a median of £2,276,987, while flat/maisonette homes are the most affordable at £104,000. Over the past year, flat/maisonette homes moved the most (-45.3%).
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 | £287,500 | -26.8% | 8 |
| Detached | £510,000 | +4.6% | 3 |
| Other | £2,276,987 | -8.9% | 2 |
| Flat/Maisonette | £104,000 | -45.3% | 1 |
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.
