An LED neon sign is a logo or lettering formed from flexible LED tube that imitates glass neon, running at 12 or 24 volts and usually mounted on an acrylic backboard.
Script on a café wall, a slogan behind a bar, a logo in a salon window: LED neon has become a go-to feature sign for interiors. It recreates the line-of-light look of glass neon, but the light comes from LEDs inside a flexible silicone or PVC sleeve, so the sign is lighter, cool to the touch and runs at low voltage.
Because the flex bends to almost any shape, signs are built from your own artwork rather than a stock design, from small window pieces to signs over a metre wide. This guide compares LED neon with glass, explains indoor and outdoor versions, backboards, dimmers, remote control and running costs, and covers when a sign visible from the street needs advertisement consent.
How does LED neon compare with glass?
Glass neon is gas sealed in hand-bent glass tubes, lit by a transformer at high voltage. It has a lovely, even glow, but it's fragile, can hum, and a high-voltage installation needs a fire-fighter's switch under the wiring regulations. LED neon runs at 12 or 24 volts from a driver, so it's simpler to install.
Good LED flex gives a continuous line with no visible dots, doesn't flicker and survives knocks that would shatter glass. It has limits: the flex has a minimum bend radius, so very small or intricate lettering needs simplifying, and the sleeve is a fixed width rather than hand-shaped.
- LED neon: 12 or 24 V, light and shatter-resistant
- Glass neon: high voltage, fragile, fire-fighter's switch
- LED neon's limit: a minimum bend radius
Can LED neon be used outdoors?
Yes, if it's built for it. Outdoor-rated flex has a sealed, UV-stable sleeve and end caps, sealed connections and an outdoor-rated driver mounted somewhere sheltered. Look for an ingress protection rating of IP65 or higher on the flex and connectors. Outdoor neon suits canopies, covered terraces and fascias, where some shelter helps it last.
Outside, the flex is usually fixed directly to the fascia, render or a weatherproof backboard rather than a thin interior panel, and an electrician hard-wires it to the mains to BS 7671 rather than using a plug. An interior sign moved outdoors can fail quickly once moisture reaches the joints.
- Outdoor-rated flex, connectors and driver
- Driver sheltered from rain but still reachable
- Hard-wired connection by an electrician
Which backboard suits your sign?
Most LED neon is mounted on acrylic. Clear acrylic lets the wall show through so the lettering seems to float, and it can be cut as a rectangle or contour-cut close around the design so the board almost disappears. Coloured, black or mirrored acrylic frames the sign and hides a busy wall.
Signs are fixed with stand-off fixings through the board, hung on fine wires or chains for windows, or set on a stand for counters and events. The driver and its cable usually run down the wall to a socket, so plan the cable route before choosing the position.
- Clear rectangle: simple and discreet
- Contour-cut clear: the lightest look
- Black or coloured: strongest contrast
- Frosted acrylic: softens the wall behind
How do dimmers and remote controls work?
An inline dimmer or small remote receiver sits between the driver and the sign, so you can soften the light in the evening or turn it up against daylight in a window. Single-colour signs simply dim smoothly; colour-changing signs use RGB flex with a controller that holds one colour or moves between them.
Animated and chasing modes can work well inside a venue, but anything facing the street should stay static, because flashing illuminated signs generally need specific advertisement consent. A plug-in timer or smart socket switches the sign on and off at set times, which also keeps the running cost down.
- Dimmer for brightness, remote for convenience
- RGB controller for colour changes indoors
- Timer or smart socket for automatic switching
Where does LED neon work well?
Inside venues where people linger and look around. Cafés use a slogan on a feature wall that customers photograph and share; bars put a logo or phrase behind the counter; salons and barbers hang one in the window or above the mirrors. Offices use neon in receptions and meeting rooms, and events use plug-in signs at launches, weddings and trade stands.
Position matters as much as design. Keep the sign out of direct sunlight, which washes out the colour, and plan a tidy cable route. A plain or dark wall makes the colours stand out; a patterned wall may need a coloured backboard.
- Hang at or just above eye level
- Keep the driver ventilated, not hidden in fabric
- Leave space around the sign

How much do LED neon signs cost?
Guide prices: £245–£495 + VAT for a sign up to 600 mm, and £450–£1,250 + VAT for 600 mm–1.2 m. An outdoor-rated version adds a guide £150–£450 + VAT. Prices exclude VAT and are confirmed after an artwork check.
Total flex length drives the price, so dense script costs more than short words. Extra colours, shaped backboards, dimmers or RGB control and hard-wired fitting add to it; larger signs are quoted individually.
| Item | Guide, ex VAT | Inc. VAT (20%) |
|---|---|---|
| LED neon sign up to 600 mm | £245 – £495 | £294 – £594 |
| LED neon sign 600 mm–1.2 m | £450 – £1,250 | £540 – £1,500 |
| Outdoor-rated version | £150 – £450 | £180 – £540 |
Guide prices exclude VAT and are confirmed after survey or artwork check. Basis: LED neon flex on clear or coloured acrylic, up to about 1.2 m wide, with plug-in driver.
Permission and rules
A neon sign on an inside wall, away from the windows, is usually outside advertisement control. Once it's visible from the street, on a fascia, canopy or just behind the glass, it can count as an illuminated advertisement. In England, lit signs get only limited deemed consent, and none in conservation areas, National Parks, National Landscapes, the Broads or areas of special control; an express consent decision usually takes up to 8 weeks. Keep street-facing signs static. Wales, Scotland and Northern Ireland have their own regulations. We can prepare the drawings and photos for an application, or submit it for you.
