In London, England, local planning authorities enforce planning control through enforcement notices and breach of condition notices to protect amenity and the development plan. This guide explains what those notices do, who issues them, how to respond, and practical next steps for homeowners, developers and agents. For statutory detail and central guidance see the primary sources linked below.[1] [2]

What are Enforcement and Breach of Condition Notices?

Local planning authorities (LPAs), including London boroughs and the City of London Corporation, use enforcement notices to require the cessation, remediation or removal of unauthorised development. Breach of condition notices require compliance with conditions attached to an existing planning permission.

Respond promptly to any formal notice; timescales are strict.

How enforcement is started

  • Complaints: members of the public can report suspected breaches to their local council planning enforcement team.
  • Investigation: the LPA investigates and decides whether formal action is justified.
  • Formal notices: if action is taken, the LPA serves the appropriate notice on the owner and any occupier.

Penalties & Enforcement

Enforcement powers and sanctions are set out in national planning legislation and guidance and are implemented by London LPAs. Exact fines and sentencing levels are not always listed on LPA pages and may be determined by statute or court sentence; where an exact monetary figure is not given on the cited page, this is stated below.[2]

  • Monetary penalties: specific fine amounts for breach and non-compliance are not specified on the cited guidance page.
  • Criminal prosecution: persistent non-compliance can lead to prosecution and court-imposed fines or remedial orders; exact maxima may be set by statute or by the court.
  • Direct action and costs: an LPA may carry out works in default and recover costs from the owner; the process and recoverable costs are set out in statute or guidance.
  • Injunctions and seizure: courts can grant injunctions, and in some circumstances assets may be seized if offences continue.
If you receive a notice, check deadlines immediately and get formal advice if unsure.

Escalation and repeat offences

  • First and continuing offences: guidance explains the LPA may escalate from advisory action to formal notices; specific escalation fines or day-rates are not specified on the cited guidance page.
  • Court escalation: persistent breaches may be prosecuted or referred for civil injunctions under court powers.

Enforcer, inspections and complaints

  • Enforcer: the local planning authority (your London borough or the City of London) enforces planning control.
  • Complaints and reports: use your local council planning enforcement contact or the national guidance to find your LPA and reporting routes. Guidance on planning enforcement
  • Inspections: an LPA officer may visit the site to establish whether a breach has occurred and collect evidence.

Appeals, reviews and time limits

  • Appeals: there are specific appeal routes for enforcement notices and related notices; consult the statutory appeal process and the Planning Inspectorate for deadlines and how to lodge an appeal.
  • Time limits: appeal time limits are set out in statute and guidance; where a precise statutory deadline is not given on the cited guidance page, it is described as "not specified on the cited page" and you should check the notice itself and official appeal guidance.

Defences, discretion and mitigation

  • Defences: lawful use, planning permission, or having a reasonable excuse may be relevant; the LPA has discretion and guidance explains enforcement should be proportionate.
  • Retrospective remedies: applying for retrospective planning permission, agreeing variations, or complying with conditions can resolve many notices.
Applying early for retrospective permission can often avoid prosecution.

Common violations

  • Unauthorised building works or extensions.
  • Change of use without permission.
  • Failure to comply with planning conditions (noise limits, hours, landscaping).

Applications & Forms

Most LPAs accept applications for retrospective planning permission and for variation/discharge of conditions via the national planning application process or their online portals. Specific form numbers and fees vary by council and are published on each LPA website; a central guidance page explains enforcement but does not list every local form or fee.[1]

Action steps

  • If served: read the notice immediately and note the compliance deadline.
  • Appeal: lodge an appeal or challenge within the timescale stated on the notice; seek professional advice for grounds and submissions.
  • Comply or apply: either comply with the notice or apply for retrospective permission/variation to resolve the breach.
  • Contact: notify and liaise with the LPA early to discuss mitigation and possible timescales for compliance.
