LED neon signs in Cardiff

Very little, because LED flex draws a modest wattage per metre. For an estimate, multiply the driver's rating in kilowatts by the hours lit and your price per kilowatt-hour. A timer plug stops it running overnight when nobody's there to see it.

Yes. Interior LED neon is light and plugs into a normal socket, so it travels well to trade shows, launches and pop-ups. A padded case protects the acrylic edges. Some venues ask for portable appliance testing, so check their rules first.

Yes. Smart Signs covers Cardiff and the rest of South Glamorgan 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.

Not with a decent driver. LED neon gives a steady light, without the hum ageing glass-neon transformers can make. If a sign starts flickering, a loose connector or failing driver is the usual cause, and both are simple to replace.

As a guide, £245–£1,250 per sign + VAT. Where your job falls in that range depends on size, materials, access height, whether old signage has to come off and how much design work is involved. We confirm a fixed price after a survey or artwork check, before anything is ordered.

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.
