How long does the process take?

Making and fitting typically takes 3–5 weeks after you approve the proof. Where express advertisement consent is needed, allow for the council's decision too, usually up to 8 weeks, and plan for production to start once the decision is in.

Do you work across South Glamorgan or only in Cardiff?

Across all of South Glamorgan, and the rest of the UK too. Cardiff is simply one of the places we list, and enquiries from anywhere nearby follow exactly the same steps: photos or a survey, a scaled proof, a written price, then making and fitting once you sign off the design.

How bright should lit letters be?

Bright enough to read clearly without glare. Councils often assess brightness against the Institution of Lighting Professionals' PLG05 guidance, which sets lower limits in darker, residential areas than in town centres. Dimmable drivers let the output be turned down after fitting if needed.

Can our non-lit letters be converted?

Rarely in a way that's worth paying for. Solid built-up or flat-cut letters have no translucent face or space for LEDs, so converting them means rebuilding them. Lighting the existing letters from outside with a trough light or spotlights usually costs less.

Is there a typical lead time for illuminated built-up letters in Cardiff?

Yes, though it varies with the job. The lead time typically runs from the day you approve the proof, not from the first enquiry, and is typically a few weeks. Survey visits, artwork changes and any consent application sit before that point, so getting photos, sizes and logo files to us early typically shortens the overall timescale.

Why is there a price range for illuminated built-up letters rather than one figure?

Because jobs vary. The guide of £140 to £360 per letter + VAT spans small, simple work at one end and larger, more involved work at the other. Size, material, finish, access, design time and any consent drawings push the figure up or down. A survey or artwork check lets us fix the price for your job in Cardiff.

Consent for illuminated signs in South Glamorgan

Wales has its own advertisement regulations, and a lit sign is the case where they matter most. Internally illuminated, halo-lit and lit projecting signs typically need express consent, and on listed buildings or in conservation areas the council is likely to look closely at size, light levels and fixings. Keep illumination static and moderate; PLG05 from the Institution of Lighting Professionals is the usual reference. LED modules and drivers run at low voltage, but the mains connection still needs an electrician working to BS 7671. We check before you commit and can prepare or submit the consent application.

Options worth considering
