Schools & Ofsted
Catchment area is the #1 driver of family-let demand and exit liquidity in the suburbs. Verify the local primary + secondary ratings before offering — an Outstanding catchment can add 5–10% to £/sqft; Inadequate is a permanent drag.
- All schools within 2 miles (DfE GIAS) — official register, last Ofsted, type
- Ofsted reports for TW16 5PW — full inspection reports + history
- Catchment visualiser (Locrating) — free-tier school-catchment map
Catchments aren't published nationally; many schools use distance-from-school as the deciding factor. The links above give you the official data; only the local authority can confirm a specific year's catchment boundary.
HMO licensing
No curated HMO data for this area. Most UK councils run mandatory licensing for 5+ sharers (statutory) plus area-specific additional / selective schemes. Verify with the local authority before completing a purchase.
Area pulse
- Inside an Article 4 area — HMO conversion needs planning consent (don't assume you can split it).
