Lightbox signs in Cardiff

Every business in Cardiff wants its signage to do one job properly, whether that means being read from the road, giving a little privacy or making glass obvious to people walking towards it. Our approach to lightbox signs starts there, with sizes and materials chosen for the building or vehicle in question. We work UK-wide, so enquiries from Cardiff and across South Glamorgan follow one straightforward process.

From £1,250 per lightbox + VAT · UK guide price

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.

Lightbox signs in Cardiff: questions

Can the existing wiring be reused?

Often the existing supply, switch and timer can be reused, provided an electrician checks them first. New LED drivers usually replace the old control gear inside the box. If the circuit is old or untested, the electrician will advise before connecting to BS 7671.

How do I get a quote for lightbox signs in Cardiff?

Use the quote form, phone or WhatsApp and include a few photos, rough sizes and any logo files you have. We check the details, arrange a survey where one is needed, then send a fixed written price with a design drawn to scale. The quote is free, and nothing is made until you approve it.

Do lightboxes let in water and insects?

A well-made box is sealed around the face, with small drainage holes along the bottom so condensation can escape. LEDs run much cooler than tubes, so less heat draws insects in. Taking the face off occasionally to clean inside keeps the light even.

Can I get a fixed price for lightbox signs in Cardiff before committing?

Yes. We start from the guide range, £1,250 to £4,800 per lightbox excluding VAT, then measure up or look at your photos and artwork. That gives a fixed written price reflecting the real size, materials, access and any design or consent work. You only commit once you accept that price and approve the proof.

Could the consent process affect the timing of my job in Cardiff?

It can. Not every job needs an application, but where express consent is required the council's decision typically takes several weeks, and fitting typically waits until it is granted. We check this at the start, so the timetable you receive with your quote allows for consent where it applies, along with the proof approval stage.

How long does a printed face last?

Several years in most positions, though colours fade noticeably faster on a sunny south-facing frontage. Laminates and UV-resistant inks help slow fading, and reds and yellows usually go first. A box that's easy to re-face keeps future rebrands and refreshes affordable.
