Harrow: local evidence before choosing a home
Three public reference positions, ten independent checks and the limitations you need before treating a map result as a housing shortlist.

Explore Harrow on the mapWhat these local examples show
The Harrow & Wealdstone reference illustrates a particularly important unknown: placing the origin at a station's catalog position does not guarantee a usable walking estimate. Byron Recreation Ground also has unresolved walking evidence at its reference point, whereas St George's Shopping Centre has a usable estimate to Harrow-on-the-Hill. Preserve that uncertainty and check entrances; a nearby symbol on the basemap is not a verified route.
This page covers the official Harrow boundary (E09000015), not a single neighbourhood with the same name. Its three examples are illustrative catalog positions, not a representative sample of homes or a borough-wide verdict.
Mapped destinations in this boundary
The retained catalogs place 13 supported station records, 25 named green-space references of at least 2 hectares, 19 supported supermarket records, 3 shopping-centre records and 77 official school positions inside this boundary. These are source-position counts, not a complete inventory or proof of present access; station records can represent separate services at one interchange.
Supported lines represented here: Bakerloo, Jubilee, Lioness, Metropolitan, Piccadilly. Coverage includes Underground, Overground, DLR and Elizabeth lines, not every National Rail service. Walking destinations can lie outside the borough.
Three public reference reports
These use the independent Check profile: all supported destination choices, walks up to 30 minutes, green spaces at least 2 hectares, both noise periods and no combined score. School results use all phases and both inspection schemes; the new report-card area is Curriculum and teaching. Origins are source positions, sometimes inside a site, not verified entrances. Unknown means reliable evidence is unavailable, not a pass.

Turn this comparison into viewing questions
Choose the journeys and surroundings you actually need. Check the location of the home, the route and entrance you would use, indoor noise and current access. A missing noise value is unverified quietness; a missing supported-line result does not cover every rail service. Tube proximity does not measure vibration, crime bands do not predict personal safety, and a nearby school does not establish eligibility.
Source snapshots behind these examples
- Aircraft: Defra Round 4 (2022 mapping). Airport activity years vary and are not verified for every airport; no mapped aircraft-noise contour does not establish infrequent flights or quietness.
- Road and railway: Defra Round 4 (2022 mapping); 2021 road/rail activity; historical model, not live measurements.. Published values begin at 40 dB day / 35 dB night.
- Walking and mapped destinations: retained OSM snapshot 2026-10-30T21:24:51Z; packaged station snapshot, not live services.
- Crime: 2024-09 to 2026-08; resident population year 2024. Historical London-only bands, not safety grades.
- Schools: GIAS 2026-10-31; Ofsted 2026-09-30. Proximity does not establish admissions.
- Tube proxy: April 2026; 100 m setback, not measured vibration.
