A locality in Kettering.
Sold house prices in Islip have an overall average of £356,125, based on all 113 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 Islip, the median sold price over the 12 months to May 2026 was £281,000 — it fell 25.8% on the year before. That reflects 15 recorded sales. Detached homes are the priciest at a median of £600,000, while semi-detached homes are the most affordable at £161,500. Over the past year, terraced homes moved the most (-51.2%).
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 | £275,000 | -51.2% | 7 |
| Semi-detached | £161,500 | -42.3% | 4 |
| Detached | £600,000 | +21.2% | 3 |
| Other | £405,000 | -15.6% | 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.
