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.

Can we see the night-time look first?

Yes. The design proof shows the letters to scale on a photo of your building, and a night-time visual can show the lit effect. Where colour is critical, a sample letter or face can be lit for you to check before the full set is made.

What do LED letters cost to run?

Not much, because LED modules draw far less power than older neon and fluorescent signs. The total depends on module count and hours lit. Ask for the total wattage on your quote, and use a time switch so the sign isn't lit overnight.

Can you handle illuminated built-up letters for a business in Derry/Londonderry?

Yes. Smart Signs covers Derry/Londonderry and the rest of County Londonderry as part of a UK-wide service. You send photos and rough sizes, we arrange a survey if the job needs one, then you receive a proof to scale and a fixed written price. Nothing is made or fitted until you have approved both.

What makes illuminated built-up letters more or less expensive?

Size and quantity come first, then the material or film, any lighting, the height of the work and the equipment needed to reach it, and the state of the surface or old sign being replaced. Against that, the guide for a job in Derry/Londonderry is £140–£360 per letter + VAT, confirmed after a survey or artwork check.

What can delay illuminated built-up letters in Derry/Londonderry?

The usual causes are artwork changes after the proof stage, waiting for consent, access arrangements such as a council licence for scaffolding on the pavement, and weather for outdoor fitting. Jobs typically run smoothly once the proof is approved and any consent is in place, but we do not promise dates that depend on things outside our control.

Consent for illuminated signs in Derry/Londonderry

Light changes the consent position. Under Northern Ireland's 2015 Advertisement Regulations, internally lit, halo-lit and lit projecting signs typically need express consent from the council, applied for online through the NI Planning Portal. A listed building usually needs listed building consent as well. LED modules and drivers run at low voltage, but the final mains connection is made by an electrician to BS 7671, who certifies the circuit. Councils commonly refer to PLG05 for brightness and expect steady rather than flashing light. We check before you commit to illuminated built-up letters and can prepare or submit the application.
