The Isleworth market: activity & mix
How busy the market is, and what kind of homes actually change hands.
* 2026 is a part year — Land Registry sales are recorded a few weeks after completion.
Around 354 homes changed hands in Isleworth in 2025 — quieter than the area's average of roughly 417 sales a year over the past decade. The busiest recent year was 2017 (528 sales).
