Advertisement Consent & Planning Control in London

Signs and Advertising England 3 Minutes Read ยท published February 02, 2026 Flag of England

In London, England, advertisement consent controls the display of signs, posters, banners and other adverts that affect amenity or public safety. Local planning authorities regulate advertisements under national planning regulations and local planning policies, so you usually need to check both national guidance and your borough or the City of London planning service before installing signage. This guide explains what counts as an advertisement, when consent is required, how to apply, enforcement and typical compliance steps for businesses, landlords and residents in London.

What is advertisement consent?

Advertisement consent is formal permission from the local planning authority to display an advertisement that would otherwise be restricted by planning control. Consent considers amenity and public safety, including visual impact, illumination, highway safety and effects on conservation areas or listed buildings. Some temporary or minor adverts are permitted development and do not require consent; others require a formal application to the local planning authority. For national regulatory criteria and statutory tests see official guidance on advertisements.

Government guidance on advertisements[1]

Check both national guidance and your borough's planning pages before commissioning signs.

When is consent usually required?

  • Signs that are illuminated or moveable in a way that could distract drivers.
  • Large billboard-style adverts or multiple fascia signs on commercial premises.
  • Advertisements in conservation areas or on listed buildings (special controls apply).
  • Free-standing signs affecting the highway or pavement safety.

Penalties & Enforcement

Enforcement is carried out by the local planning authority. Typical enforcement options include enforcement notices requiring removal or modification of adverts, prosecution for non-compliance, or direct action to remove unlawful displays. Specific monetary fines and escalation are not universally listed on the local guidance page and therefore are not specified on the cited page.

  • Fines: not specified on the cited page.
  • Escalation: not specified on the cited page (local enforcement policy determines steps for first, repeat and continuing offences).
  • Non-monetary sanctions: enforcement notices, stop notices, removal orders, and prosecution through magistrates' or Crown courts where appropriate.
  • Enforcer: local planning authority (planning enforcement team); report concerns to the local planning service for investigation.
  • Appeals/review: not specified on the cited page.
  • Defences/discretion: arguments such as permitted development, temporary exemptions or reasonable excuse may be relevant; permission or retrospective consent can sometimes be sought.
If an advertisement is displayed without required consent you may be asked to remove it or apply retrospectively.

Applications & Forms

Advertisement consent applications are submitted to the local planning authority. Application routes commonly use the national planning application process and local application forms or online portals; fees and detailed requirements are set out by national guidance and local validation checklists. Contact your borough planning service for the precise form, fee and submission method.

  • Pay the application fee as set by the local authority or national fee schedule and submit via the local planning portal or in person.
  • Contact planning enforcement if you see unauthorised adverts that risk safety or amenity.
