A neon sign can transform a shop window, salon or café, but business signs come with rules that home signs don't. Most indoor neon needs no permission at all. Some illuminated signs do, depending on where they hang and how they shine. This guide explains the main UK rules in plain English so you can plan your sign with confidence.
This is general guidance, not legal advice. Rules vary between councils and between England, Wales, Scotland and Northern Ireland, so check with your local planning authority before you install an outdoor or window-facing illuminated sign.
The short version
| Where the sign goes | Usually needs permission? | What to check |
|---|---|---|
| Inside, away from windows (behind the counter, feature wall) | Usually no | Electrical safety and your lease |
| Inside, facing out within about 1 metre of a window or door | Possibly | Advertisement consent rules for illuminated signs |
| On the outside of the building | Often yes | Advertisement consent, brightness, landlord approval |
| Listed building or conservation area | More likely | Extra consents and stricter rules |
Advertisement consent: what it is
In England, business signs are covered by the Town and Country Planning (Control of Advertisements) (England) Regulations 2007. Wales, Scotland and Northern Ireland have their own versions with similar ideas. The rules sort signs into three groups:
- Excluded. Signs the rules don't cover at all. Most signs inside a building fall here.
- Deemed consent. Signs you can put up without applying, as long as you meet set conditions, such as size, height and brightness limits.
- Express consent. Signs that need a formal application to your council.
Councils judge signs on two things: amenity, meaning how the sign looks in its surroundings, and public safety, meaning whether it could distract or confuse drivers and pedestrians.
Signs inside your premises
Good news for most businesses: a neon sign inside your shop, salon, bar or office is normally excluded from advertisement control. A sign behind the counter, on a feature wall or above a seating area usually needs no permission.
The main exception is window signs. In England, an illuminated sign inside a building is not automatically excluded if it is within 1 metre of a window, door or other opening and can be seen from outside. If your neon will hang in the shop window facing the street, check whether it falls under deemed consent or needs an application.
Signs outside your premises
Illuminated signs fixed to the outside of a business can sometimes go up under deemed consent, but conditions apply. They typically cover:
- Brightness. There are limits on how bright an illuminated sign can be.
- No flashing or moving light. Animated, flashing or intermittent lighting usually needs express consent.
- Size and position. Limits on how big the sign is and how high it sits.
- Location. Deemed consent for illuminated signs is often restricted in conservation areas and other protected areas.
Our LED neon is made for indoor use, so for an outdoor sign you'd need a weatherproof product anyway. Many businesses get the same effect by hanging an indoor neon sign behind the glass of a shop window.
Listed buildings and conservation areas
If your premises are in a listed building, fixing anything to the building, inside or out, may need listed building consent as well. In conservation areas, councils tend to be stricter about illuminated signs on frontages. In both cases, talk to your council's planning team before you order.
Brightness, glare and neighbours
Even where permission isn't needed, keep your sign considerate:
- Avoid colours and positions that could be confused with traffic lights near a road junction.
- Don't point a bright sign into neighbouring homes. Artificial light can count as a statutory nuisance under the Environmental Protection Act 1990.
- Use a dimmer or timer so the sign isn't blazing at 2am.
A dimmer is the simplest way to keep a window sign eye-catching in the day and comfortable at night.
Your lease and landlord
Most commercial leases restrict what you can fix to the walls and frontage. Check your lease and get written approval from your landlord for anything screwed to the building or visible from outside. Shopping centres and retail parks often have their own signage guidelines too.
Electrical safety at work
A plug-in neon sign is electrical equipment, so the usual workplace rules apply. The Electricity at Work Regulations 1989 require businesses to keep electrical equipment safe. In practice:
- Include the sign and its adapter in your regular electrical checks or PAT testing.
- Keep the adapter ventilated and the cable where it can't be tripped over or pulled.
- Keep signs away from water, steam and splash zones such as sinks and coffee machines.
- Don't block fire exits, exit signs or escape routes with a sign or its cable.
Our guide to installing a neon sign safely covers mounting in more detail.
What your sign says
If your sign makes a claim, such as "best coffee in town" or a price, the UK advertising codes overseen by the Advertising Standards Authority still apply. Keep claims honest. Most business neon is a logo, name or short phrase, so this rarely causes problems.
A simple checklist before you order
- Decide where the sign will hang: inside, in the window or outside.
- If it faces out within about 1 metre of a window or goes outside, check with your council.
- Check whether your building is listed or in a conservation area.
- Get written landlord approval if needed.
- Plan the power: nearest socket, cable route and a dimmer or timer.
- Add the sign to your electrical safety checks once it's up.

Frequently asked questions
Do I need planning permission for a neon sign inside my shop?
Usually not. Signs inside a building are normally excluded from advertisement control. Illuminated signs within about 1 metre of a window and visible from outside may be treated differently, so check with your council.
Can I put a neon sign in my shop window?
Yes, many businesses do. Keep it indoors behind the glass, as our signs are not waterproof, and check the rules for illuminated window signs with your council.
Do neon signs need PAT testing in a business?
Businesses must keep electrical equipment safe, and PAT testing is the usual way to show this. Include your sign and its adapter in your regular checks.
