Frequently asked questions

Where does this planning application data come from?
Every application on this page comes from Harrow Council's public planning register (planningsearch.harrow.gov.uk). Plota collects it, adds a map location and a category, and links each record back to the council's own entry, which is the authoritative version.
How often is this page updated?
Plota checks Harrow Council's register every day and adds new applications, status changes and decisions as the council publishes them. The register was last checked on 7 Oct 2026.
Where can I see the plans and documents for an application?
Plans, drawings and officer reports are held on Harrow Council's own website. Where the council publishes a document list, it appears on the application's page here with each item linking to the council's copy; otherwise the "View original council record" link on every application opens the council's entry.

About this data

Plota holds 3,543 current planning applications from Harrow Council, received since 7 Nov 2017, 618 of them in the last 90 days. Behind them, the Plota archive holds 43,373 earlier applications from Harrow Council, 2016 to 2025, searchable by location and keyword. Current records are collected from the council's public register at planningsearch.harrow.gov.uk and checked every day; the last check was on 7 Oct 2026. Each record carries the council's reference, address, proposal, dates, status and decision, with a map location and Plota's classification by type and procedure added. The council's own record is the authoritative version; every entry here links to it.
