Temporary Signage and Advertisement Consent - Cardiff

Events and Special Uses Wales 4 Minutes Read · published February 12, 2026 Flag of Wales

Cardiff, Wales requires organisers to follow planning and highways rules when placing temporary signage or event advertising on public land. This guide explains when advertisement consent or licences are needed, who enforces the rules in Cardiff, and practical steps to apply, appeal or report unauthorised signs. It concentrates on temporary signs for events, directional banners, and roadside posters on council land.

When consent is needed

Many temporary signs used to promote events are classed as advertisements under local planning rules and may require advertisement consent from the council. Signs on highways, street furniture, or on council-owned land may also need separate permission or a licence from highways or events teams. For official guidance on advertisements and signs see the Cardiff Council planning pages [1] and for enforcement and compliance see Cardiff Council planning enforcement information [2].

Practical rules for event signage

  • Obtain advertisement consent if the sign is a fixed or prominent display visible from a public place.
  • Seek highways permission for signs placed on or over the public highway, or for directional signs that affect traffic management.
  • Check council land bookings rules before erecting banners or freestanding boards on parks or promenades.
  • Ensure temporary signs do not obstruct visibility, footways, cycle routes or create hazards for vehicles and pedestrians.
Plan signage early to allow time for consent and any required traffic management approvals.

Penalties & Enforcement

Cardiff Council enforces advertisement and planning control through its planning enforcement and compliance functions. Where adverts are displayed without required consent the council may take enforcement action, require removal, or pursue prosecution under the relevant planning legislation. Specific monetary penalties and fine amounts are not specified on the cited enforcement page; see the official enforcement guidance for actions and notices [2].

Unauthorised signs can be removed by the council and may result in enforcement notices or prosecution.
  • Fine amounts: not specified on the cited page; consult the enforcement page for details and case steps [2].
  • Escalation: enforcement notices, removal orders or prosecution; specific escalation schedules are not specified on the cited page.
  • Non-monetary sanctions: removal orders, stop notices, planning enforcement notices and possible injunctions or court action.
  • Enforcer and complaints: Cardiff Council Planning Enforcement and Compliance team handles adverts and unauthorised development; use the council enforcement contact route detailed on the official page [2].
  • Appeals and review: appeals against planning enforcement or advertisement decisions follow statutory routes; time limits and appeal forms are set out by the council and relevant planning appeal bodies and are not fully specified on the cited enforcement page.

Applications & Forms

Advertisement consent applications are made through the local planning application process; the council publishes guidance on adverts and planning applications but does not list a separate advert-only form on the cited page. Fee information or specific application form numbers are not specified on the cited planning pages. Apply for consent via Cardiff Council planning application portals or contact the planning team for the correct application route [1].

If in doubt, contact Cardiff Planning before printing or erecting multiple signs.

Action steps for organisers

  • Plan signage locations and design to minimise highway or visibility impact and prepare clear site plans for any application.
  • Submit an advertisement consent request via Cardiff Planning where signs are permanent or highly visible from public places.
  • Request highways permission or a temporary road/street licence for signs placed on the highway or requiring traffic management.
  • If signs are removed or you receive an enforcement notice, contact the planning enforcement team immediately and follow appeal or compliance instructions on the official page.
