Cardiff, Wales regulates the siting of advertising hoardings and signs to protect road safety at junctions and crossings.

It summarises enforcement pathways, typical outcomes and where to find the official Council guidance and application routes.

Check visibility lines and driver sightlines before installing any large sign near a junction.

Scope & legal basis

Local control of outdoor advertising in Cardiff sits alongside national planning controls and the Council's enforcement policy. In practice, advertising near junctions is assessed for its effect on driver sightlines, distraction and pedestrian safety. Where a separate advertisement consent is required, applicants must follow the planning application process and any conditions imposed by the Council.

Penalties & Enforcement

Cardiff Council enforces advertisement controls through its Planning and Enforcement teams and may require removal or modification of unauthorised signs. Specific monetary penalties and fixed penalty amounts for billboard setbacks are not specified on the cited Council guidance page; see the Applications & Forms section for the Council source.[1]

  • Fines and financial penalties: not specified on the cited page.
  • Escalation: first-time notices followed by enforcement notices; specific escalation schedules not specified on the cited page.
  • Non-monetary sanctions: enforcement notices, removal orders, and court action for failure to comply.
  • Enforcer and contacts: Planning Enforcement and Development Management within Cardiff Council handle advertising enforcement.
  • Appeals and review: appeals against enforcement notices proceed via the Planning Inspectorate or relevant appeal body; statutory time limits apply for notices and appeals but specific periods are not specified on the cited page.
  • Defences and discretion: permitted development rights, existing lawful use, or an approved advertisement consent may be defences; the Council exercises discretion by applying conditions or granting consent with safeguards.
Enforcement action typically begins with an informal request before formal notices are issued.

Common violations

  • Signs placed within required sightlines at junctions causing obstruction or glare.
  • Illuminated hoardings that distract drivers or exceed permitted illumination levels.
  • Adverts displayed without required advertisement consent or planning permission.

Applications & Forms

To apply for advertisement consent or check whether consent is required, use the Council's guidance on display of advertisements and the planning application process. The Council's page lists how to submit applications and links to application portals and contact points. Cardiff Council - Display of advertisements[1]

If in doubt, submit a pre-application enquiry to Development Management before installing a major hoarding.

Action steps

  • Assess sightlines: commission a visibility study if the billboard is near a busy junction.
  • Apply for advertisement consent via the Council planning portal when required.
  • Report unsafe or unauthorised signs to Cardiff Council Planning Enforcement.
  • Comply promptly with any enforcement notice to avoid escalation and potential court action.
