Do I need an electrician for plug-in solar?
Usually not. An approved kit is designed for you to set up yourself.
You plug it into a suitable standard wall socket, using the plug it comes with. The official rules don’t require an electrician to install it, or to check your home first.
But you can’t just use any socket, and some homes will need an electrician to check or change things first. Electrical Safety First, a UK safety charity, recommends getting your electrics checked before you buy, especially in an older home.
Call an electrician if
Your fuse box is old
You can’t check your safety switches
The socket is damaged
You need a new socket
You’re unsure which sockets are linked
The panels add up to over 960W
● You can do it
What can I do myself?
An approved kit is made to be set up at home.
Put up the panels, following the kit’s instructions
Plug the kit’s own plug into a suitable wall socket
Use a suitable socket indoors or outdoors — if it’s outside, it needs to be a proper weatherproof socket rated IP55 or better
Register it online before, or when, you switch it on
● Call an electrician
What needs an electrician?
Anything that changes your home’s wiring, or anything you’re unsure about.
Fitting a new socket, including an outdoor one
Checking, upgrading or replacing your fuse box
Checking a socket that’s damaged or worn
Working out which sockets are on the same circuit
Required or advice?
What’s a rule, and what’s just good advice
Some of this comes from the official plug-in solar rules. Some is safety advice. Here’s which is which:
Is it required?
Use an approved kit, listed as compliant
Required
Register it before, or when, you switch it on
Required
Plug the kit’s own plug into a standard 13A wall socket
Required
Use a weatherproof socket if it’s outside
Required if outside
Only one kit in your home
Required
Extension leads and adaptors
Not allowed
A damaged or worn socket
Not allowed
An electrician to install it
Not required
A new or dedicated socket
Not required
Have your electrics checked first
Recommended
A Type A safety switch or better
Recommended
Wiring changes done by an electrician
Required if needed
“Required” means the official rules, or the instructions every approved kit must come with, say so. “Recommended” is safety advice, mainly from Electrical Safety First. For what the law itself allows, see Is plug-in solar legal in the UK?
Sockets
Which socket can I use?
A suitable standard wall socket, indoors or outdoors. You don’t need a special or dedicated one.
What makes a socket suitable:
It’s an ordinary UK 13A wall socket in good condition: not cracked, scorched, loose or wobbly.
If it’s outside, like the socket on your patio, it’s a proper weatherproof outdoor socket, rated IP55 or better.
It’s on your home’s ordinary socket wiring. Electrical Safety First advises against a socket on a lighting circuit or one that supplies a cooker or hob.
No other plug-in solar kit is plugged in anywhere in your home.
The inverter, the small box that turns the panels’ electricity into mains electricity, can be indoors or outdoors depending on the kit. Follow the kit’s instructions for bringing the cable inside.
Not sure whether a socket is suitable, or which sockets share the same wiring? Ask an electrician.
Plugging in
Can I use an extension lead or adaptor?
No. The kit’s own plug has to go straight into the wall socket. The official rules don’t allow:
Extension leads or cable reels
Multi-way adaptors
Travel adaptors or plug converters
Plug-in safety (RCD) adaptors
Approved kits carry this warning on the plug itself.
Smart plugs and timers aren’t mentioned in the rules by name. But the kit is designed to plug directly into the wall socket, so don’t put anything in between.
Your fuse box
Is my fuse box OK?
It needs modern safety switches. If you have an old-style fuse box, get an electrician to check it before you plug anything in.
Your fuse box (also called a consumer unit) has safety switches that cut the power if something goes wrong. You can usually spot the important ones, called RCDs or RCBOs, by a small “T” or “Test” button.
Every approved kit must tell you to check that your home has modern protection like this. If it doesn’t, and still uses older fuses, the kit’s instructions say a professional electrician should check it and upgrade it if needed.
What type of safety switch?
Electrical Safety First recommends that the socket you use is protected by a safety switch of at least “Type A”, and one designed to work with electricity flowing in either direction, which an electrician can confirm. It advises that homes with the older “Type AC” shouldn’t use plug-in solar until it’s upgraded. This is safety advice rather than part of the official rules, but we’d follow it.
The type is usually shown by a small letter or symbol on the front of the switch. Don’t take the cover off your fuse box. If you can’t tell, note the make and model on the front and ask the manufacturer or an electrician.
When you need one
When do I need an electrician?
Whenever your home’s wiring needs changing, and whenever you’re unsure.
You need a new socket, including an outdoor one.
Your fuse box needs checking, upgrading or replacing.
A socket is damaged, or you’re not sure it’s safe.
You can’t tell which sockets are on the same circuit.
Your kit’s panels add up to more than 960W. The official rules say you should consider getting your electrics assessed first. More panels than 800W explains why kits can have more.
The official rules say any change to your home’s wiring for plug-in solar is a job for a qualified electrician. A registered electrician will also deal with any building regulations paperwork.
Across the UK
England: a new circuit or a new fuse box has to be notified under building regulations.
Wales: the same, plus some smaller jobs, such as adding an outdoor socket.
Scotland: it has its own building standards. Many smaller wiring jobs in a house don’t need a building warrant, but it still has to meet the standards.
Northern Ireland: the new plug-in solar rules don’t cover Northern Ireland yet. See Is plug-in solar legal in the UK?
Before you plug in
Your checklist
01
Check it’s approved
Make sure the exact model is listed as compliant. How to check.
02
Check the socket
A standard wall socket in good condition. Outdoors, a weatherproof one.
03
Check your fuse box
Modern safety switches, ideally Type A or better. If in doubt, ask an electrician.
04
Plug straight in
Use the kit’s own plug. No extension leads, adaptors, smart plugs or timers.
05
Stick the label on
Put the label that comes with the kit on or near your fuse box, so anyone working on it knows there’s solar plugged in.
06
Register it
Register before, or when, you switch it on. Doing it beforehand is simplest. How to register.
Good to know
Common questions
Do I need my electrics inspected first?
It isn’t required by the official rules. But Electrical Safety First and the IET, the engineering body behind the UK wiring rules, both recommend having a competent electrician check your electrics before you buy, especially in an older home or if you’re not sure what’s in your fuse box.
Do I need a dedicated socket?
No. The kit plugs into an existing wall socket. You only need a new socket if there isn’t a suitable one where you need it, and fitting one is a job for an electrician.
Can the inverter go indoors?
Yes, if the kit is designed for it. Some kits keep everything outside and use a weatherproof outdoor socket; others bring the cable inside. Follow the kit’s instructions.
Can I plug in two kits on different circuits?
No. Network rules currently allow one plug-in solar kit per home. What the rules allow.
I rent. Can I still set it up myself?
Yes, but you’ll need permission from your landlord first, and possibly from a freeholder or managing agent. The same socket and fuse box checks apply.
Does WattVerdict check sockets or wiring?
No. We check whether systems are listed as compliant, and our testing measures how they perform. We can’t check your home’s wiring. That’s a job for an electrician.
