Do I need planning permission for plug‑in solar?
Usually not in England, if you stay within a few simple limits. The big catch is anything wooden. Here’s the answer for where you want to put it.

Do I need planning permission for plug-in solar?
Usually not in England. But anything wooden is the catch.
Since 27 August 2026, England’s planning rules have covered plug-in solar. Most set-ups on a wall, balcony, roof or in the garden don’t need a planning application, as long as they stay within some size limits.
But if any part of the kit is fixed to something wooden, like a wooden fence, gate or balcony, you need to apply. Listed buildings have extra restrictions, and may need listed building consent as well. Wales, Scotland and Northern Ireland have their own rules.
It depends on
Where it’s fixed
Whether that’s wooden
How far it sticks out
House or flat
Listed or conservation area
Which UK nation
● No application needed
When don’t I need to apply?
In England, when all of these are true.
It’s on a wall, balcony railing, roof or in the garden, within the size limits below
Nothing it’s fixed to is wooden or clad in timber
Your home isn’t a listed building
It isn’t on a road-facing wall or balcony in a conservation area
● You’ll need to apply
When do I need to apply?
Needing permission doesn’t mean it’s banned. It means asking your council first.
Any part is fixed to a wooden fence, gate, wall or balcony, or to timber cladding
Your home is a listed building, or in the grounds of one
It sticks out further, or stands taller, than the limits allow
It’s on a road-facing wall or balcony in a conservation area or World Heritage Site
England
Where are you putting it?
These are England’s limits for a house. If your set-up fits, you don’t need to apply.
Where
No application needed if…
Wall of your house
It sticks out no more than 40cm (20cm if the wall is right beside a road or pavement)
Balcony or roof-terrace railing
The same: no more than 40cm, or 20cm beside a road or pavement
Sloping roof
It sticks out no more than 20cm and isn’t higher than the top of the roof
Flat roof
It’s no more than 60cm higher than the highest part of the roof
Garden, on a frame
The panels total no more than 9 square metres, within the height limits below
Fence, gate or garden wall
It isn’t wooden, and it’s within the height limits below
Height limits in the garden
Within 5 metres of your boundary: no higher than 2 metres.
Within 5 metres of your boundary and in front of the house: no higher than 1 metre.
Anywhere else in the garden: no higher than 4 metres.
Wherever it goes, the rules say it should be placed to affect the look of the building and the area as little as possible, and taken down when it’s no longer needed.
The catch
The wooden rule
This is the one that catches people out. If any part of a plug-in solar kit is fixed to something wooden, England’s rules don’t cover it, and you need to apply for planning permission.
A wooden fence or gate
A wooden wall or other wooden boundary
A wooden balcony
Any part of the building clad in timber
It’s about what the kit is fixed to, not whether it’s a fence. A metal railing or a brick wall is treated differently from a wooden one.
There’s a separate safety rule too. The official plug-in solar product rules say kits mustn’t be fitted to timber balconies or timber cladding at all, because of fire risk. So for those, planning permission on its own wouldn’t be enough. What the plug-in solar rules allow.
Protected places
Listed buildings and conservation areas
These have tighter rules in England.
Listed building: you need planning permission, for the building and anything in its grounds. You may also need listed building consent, which is a separate application.
Conservation area or World Heritage Site: you need to apply if it would go on a wall, balcony or roof terrace that faces the road. In the garden, extra limits apply, and you may need your council’s approval first.
Scheduled monument: you need to apply.
Not sure whether your home is listed or in a conservation area? Your council’s planning department can tell you.
Flats and renting
I live in a flat, or I rent
Two separate things apply: the planning rules for flats, and permission from whoever owns the building.
Planning rules for flats in England
On a wall or sloping roof, it can stick out no more than 20cm. That’s half the limit for a house.
On a flat roof, it can be no more than 60cm higher than the highest part of the roof.
The rules don’t give a specific projection limit for a flat’s balcony railing, so check with your council before fitting one. What else to check for a balcony.
Wooden walls, wooden balconies, timber cladding and listed blocks aren’t covered, so you’d need to apply.
Permission from your landlord or freeholder
Planning permission and your landlord’s permission are different things. Even where no planning application is needed, renters and leaseholders will usually need consent from the landlord, freeholder or managing agent before fixing anything to the building.
Outside England
Wales, Scotland and Northern Ireland
England’s new rules don’t apply in the other nations. None of them has planning rules written specifically for plug-in solar yet, so the general rules for home solar panels apply.
Wales: panels on a house can stick out no more than 20cm from the wall or roof. In the garden, one free-standing set-up is allowed: up to 9 square metres, no higher than 4 metres (2 metres near the boundary) and at least 5 metres from the road. A listed building needs planning permission, and is likely to need listed building consent too. The Welsh Government’s guidance doesn’t mention balconies or fences, and tells people in flats to ask their council.
Scotland: panels on a house or flat can stick out up to 1 metre from the wall or roof. In a conservation area, they have to go on the back, or on a side that doesn’t face a road. Listed buildings aren’t covered. The guidance doesn’t mention balconies, railings or fences.
Northern Ireland: the plug-in solar rules don’t cover Northern Ireland yet, so planning is the second question. See Is plug-in solar legal in the UK?
If the guidance doesn’t cover your set-up, ask your council’s planning department before you fix anything.
Before you fix anything
Your checklist
01
Check what it’s fixed to
If any of it is wooden, you’ll need to apply in England.
02
Measure it
How far will it stick out, and how tall will it stand? Compare that with the limits above.
03
Check for protections
Ask your council whether your home is listed or in a conservation area.
04
Get the owner’s permission
If you rent or own a leasehold flat, ask your landlord, freeholder or managing agent.
05
Follow the kit’s instructions
Approved kits come with mounting rules of their own, including places they mustn’t be fitted.
06
Then sort the electrics
Check whether you need an electrician, and register the kit before, or when, you switch it on.

Common questions
Does needing planning permission mean I can’t do it?
No. It means you have to apply to your council and get approval before you put it up. It isn’t a ban.
Is a wooden fence really treated differently from a metal one?
Yes, in England. The rule is about plug-in solar fixed to a wooden fence, gate, wall or other boundary. The same panel on a metal fence or railing isn’t caught by it, though the size and height limits still apply.
What if the panel just stands on the ground?
A free-standing set-up in your garden comes under the garden limits above. We can’t tell you that a panel which isn’t fixed down falls outside planning rules altogether. If you’re unsure, ask your council.
What if mine was already up before 27 August 2026?
The new rules include a one-year changeover. Something the old rules allowed, but the new ones don’t, can still go ahead until 26 August 2027. How that applies to your own set-up isn’t spelled out, so check with your council before relying on it.
Does planning permission cover my landlord’s permission?
No. They’re separate. You may need both, and listed building consent is separate again.
Where do I apply?
Through your local council’s planning department. It can also tell you whether you need to apply at all.
