A lightbox sign is a shallow enclosed box with a translucent face and LED lighting inside, so the whole panel, or just lettering routed into it, glows evenly at night.
Why choose lightbox signs for a business in Cardiff?
- Taking over a franchise or a new lease in Cardiff? A replacement face keeps the existing box and wiring.
- A Cardiff takeaway trading mostly after dark keeps its name and number readable with a fully lit face.
- When an old fluorescent box above a Cardiff shop flickers, an LED conversion can cost far less than a new sign.

Consent for illuminated signs in Cardiff
Illuminated fascia and projecting signs in Wales usually need express consent from the council under the Town and Country Planning (Control of Advertisements) Regulations 1992, as amended. Because the Welsh rules differ in detail from England's, we check with the planning authority what applies to your building, especially in a conservation area or on a listed building, where listed building consent may also be needed. Councils commonly look at brightness against the ILP's PLG05 guidance and expect static lighting. The final connection to the mains is made by an electrician to BS 7671, and you receive the certificate. We prepare the drawings and photos, or submit the application for you.
