Cardiff Sign Size, Height & Material Bylaws

When do signs need consent
Most permanent signs visible from a highway or public place require advertisement consent under the Town and Country Planning (Control of Advertisements) Regulations; local planning rules and site constraints can also require consent. Always check with Cardiff Council planning before installing a new sign or changing materials to avoid enforcement action Town and Country Planning (Control of Advertisements) Regulations 2007[1].
Design: size, height and materials
Cardiff planning considerations typically focus on public safety, visual amenity, and conservation area or listed building impacts. Consider these practical checks before design and installation:
- Measure the sign face and confirm it does not obscure highway sightlines or traffic signs.
- Keep mounting height clear of pedestrian obstruction and allow safe clearance for maintenance.
- Choose non-reflective, durable materials in conservation areas to reduce visual harm.
- On listed buildings, substrate, fixings and reversibility are key; work may need listed building consent as well as advertisement consent.
