Contacting your energy supplier about a problem
If you’re having a problem with your energy supply, call or use webchat to contact your supplier straight away. You can get their contact details from their website.
Tell them what’s happening, and what you want them to do about it. They might be able to sort it out then and there.
You should note down the:
date and time you get in touch
person you speak to
problem you talk about
If your supplier doesn't solve your problem while you're on the phone or webchat, send them an email or letter repeating what you said. This means you’ll have a record of your conversation with your supplier.
When you write to your supplier include your account number and any case reference numbers you have. This makes it quicker and easier to sort out your problem.
If you can't get an answer from your supplier
If your supplier won't answer the phone or send you a reply in writing, you can complain.
Contact the Citizens Advice consumer helpline if you need more help - a trained adviser can give you advice over the phone, online chat or by email.
The consumer service can help you if you:
have tried to contact your supplier and not got through
contacted your supplier but your problem hasn’t been fixed
have been disconnected or think you might be disconnected
have complex problems with your energy supply - for example, if your energy supply was switched without your agreement
are considered to be ‘vulnerable’ by your supplier
You could be classed as vulnerable if you:
are disabled or have a long-term health condition
are recovering from an injury
have mental health problems
don't speak or read English well
have children under 5 or are pregnant
have reached your State Pension age
Making a complaint
The first thing you should do is gather any supporting evidence. What you’ll need depends on your issue - for example you could:
take photos of a faulty meter
get together copies of unusual bills
gather notes from phone calls you’ve had
look for emails from your supplier about the problem
You’ll also need details of your complaint and your energy account number to hand. You can find this on a recent bill.
When you’re ready, you can complain to your supplier over the phone, or in writing by email or post.
Look online for your suppliers ‘complaints procedure’ - this should be listed on their website, and includes contact details for complaints.
Complain over the phone
You’ll need to explain the problem when you call, and tell them how you’d like them to resolve it - for example, by giving you money back if you’ve been overcharged.
Ask them how long it’ll take for their response, and if they have a reference number for the complaint.
It’s a good idea to note down the time and date you call, and who you speak to - you might need to prove this later.
Complain by email or post
When you put your complaint in writing, you’ll need to explain:
what the problem is, and when it started
how your supplier can resolve it - for example, by giving you money back if you’ve been overcharged
If you’re complaining in writing, you can fill in this template letter. You can email it or print and post it - the email and postal addresses are listed in your supplier’s complaints procedure.
Ask the Post Office for proof of postage - you might need to prove when you sent the letter.
You can complain by email using the address listed in your supplier’s complaints procedure. If you can’t find an email address, you can call your supplier and ask them for it.
Make sure you keep a copy of any emails you send to or receive from your supplier - you might need to refer to them later.
What happens next
Your supplier will get in touch with you if they need any more details about your complaint.
They should send you a ‘decision letter’ or ‘letter of deadlock’ within 8 weeks. This explains how they’ll deal with your complaint.
If you need to take your complaint further
You can complain to the energy ombudsman after complaining to your supplier if you:
have a letter of deadlock and aren’t happy with the decision
didn’t get a decision letter or letter of deadlock within 8 weeks
The ombudsman is impartial - they’ll look into both sides of the case and make a decision. If they think your complaint was dealt with unfairly, the ombudsman can make your supplier change their decision.
