Cardiff Temporary Event Signage Bylaws

Signs and Advertising Wales 3 Minutes Read · published February 12, 2026 Flag of Wales

Cardiff, Wales requires organisers and advertisers to follow local planning and highway rules for temporary event signage. This guide explains when advertisement consent or highway licences may be needed, which council teams enforce the rules, typical compliance conditions, and practical steps to apply, appeal or report a breach.

What counts as temporary event signage

Temporary event signage includes banners, A-boards, posters and flags used to promote events, sales or community activities for a limited period. Signs attached to highway furniture or visible from public highways can need separate permission from planning and highways teams.

Check both planning and highways permissions before you install any sign on or adjacent to public roads.

Key planning and highway controls

  • Advertisement consent under local planning rules may be required for temporary signs visible from the public realm. [1]
  • Highway licences or permissions are needed to place banners, signs or fixtures on street furniture or over the public highway. [2]
  • Safety conditions: signs must not obstruct visibility, footways, cycle lanes or create hazards for drivers and pedestrians.
  • Duration limits: temporary permissions often specify start and end dates and removal obligations.

Penalties & Enforcement

The council enforces signage rules through planning and highways powers and may require removal or issue penalties for unauthorised displays.

  • Fine amounts: not specified on the cited page. [1]
  • Escalation: details for first, repeat or continuing offences are not specified on the cited page. [1]
  • Non-monetary sanctions: removal notices, enforcement notices, seizure of items, and legal action through the courts are available powers under planning and highway legislation.
  • Enforcer: Cardiff Council planning and highways teams handle investigations and notices; complaints and inspections are managed via the council contact channels. [2]
  • Appeals and reviews: appeal routes depend on the type of notice (planning enforcement appeals or statutory review); specific time limits are not specified on the cited pages. [1]
  • Defences and discretion: permitted temporary displays, prior advertisement consent, valid highway licence and "reasonable excuse" defences may be considered where authorised permissions exist.
If you receive an enforcement notice, act quickly and contact the enforcing team for clarification and appeal deadlines.

Common violations and typical outcomes

  • Unauthorised banners on lamp posts — removal notice and requirement to pay removal costs.
  • A-boards obstructing pavements — fixed penalty or immediate removal.
  • Signs placed after expiry of permission — enforcement notice and possible prosecution.

Applications & Forms

Applications vary by control route:

  • Advertisement consent application via Cardiff Council planning system or planning application forms; specific application numbers or fees are not specified on the cited page. [1]
  • Highway licence or street furniture permission applications are submitted to the council highways/streetworks team; fees and form names are not specified on the cited page. [2]
Apply well before your event — processing and any required changes can take time.

FAQ

Do I always need permission to put up a temporary event sign?
Not always; signs wholly within private land and not visible from the highway may not need permission, but signs visible from public highways usually require advertisement consent or a highway licence.
Who do I contact to report an unsafe or illegal sign?
Contact Cardiff Council planning enforcement or highways team via the council contact pages listed in Resources.
How long before an event should I apply for permission?
Apply as early as possible; the council may require several weeks to process planning or highways permissions.

How-To

  1. Check whether the sign is on private land or visible from the highway and identify whether advertisement consent or a highway licence applies.
  2. Prepare clear plans and dates for the display, sizing and location, plus evidence of landowner permission if not your land.
  3. Submit the appropriate planning advertisement application or highway licence application to Cardiff Council and pay any required fee.
  4. If you receive an enforcement notice, respond within the stated deadline and follow the appeal guidance provided by the council.
  5. Remove signs promptly at the end of the permitted period and retain records of permissions and correspondence.

Key Takeaways

  • Temporary signs visible from public highways usually need advertisement consent or a highways licence.
