Land Use and Zoning England 3 Minutes Read ยท published February 02, 2026 Flag of England

In London, England, homeowners, developers and agents can appeal certain local planning decisions to the Planning Inspectorate. This guide explains who may appeal, typical procedural steps, timelines to check with your local planning authority, enforcement risks and practical actions to prepare a case for a written or hearing appeal. Appeals are handled nationally by the Planning Inspectorate but are based on the local planning authority's decision and the council's planning policies, so gather the council decision notice, application documents and any neighbour correspondence before you start.

Penalties & Enforcement

Planning appeals themselves are a review of a decision and do not impose fines, but breaches of planning control are enforced by local planning authorities under national legislation; specific monetary penalties or criminal sanctions are set out by enforcement legislation and local authority procedures and are not specified on the cited appeals page.[1]

  • Enforcement notices: can require alteration or removal of unauthorised development; monetary penalties for non-compliance vary by case and are not specified on the cited page.
  • Court action and injunctions: councils may seek injunctions or prosecutions for continued breach; fines or costs are determined by courts.
  • Continuing offences: councils can charge daily penalties or pursue prosecution for ongoing breaches, details not specified on the cited page.
  • Enforcer: the local planning authority (your borough planning enforcement team) enforces breaches; contact details are published on your borough website.
If you are under an enforcement notice, seek specialist advice promptly.
