Check if you’re responsible for paying an energy bill
This advice applies to England. See advice for See advice for Northern Ireland, See advice for Scotland, See advice for Wales
You usually have to pay for any gas or electricity you’ve used - even if you haven’t signed a contract with an energy supplier.
You shouldn't have to pay for any energy you didn't use. However, there are some situations where a supplier might ask you to pay for somebody else.
If your energy supplier didn’t send you any bills for over a year, you might only have to pay for the energy you’ve used in the last year. Check what your supplier can charge after a year.
If someone else put your name on the bill
If someone signed up to a contract in your name without telling you, you might not have to pay the bill.
You need to tell the supplier that sent the bill as soon as possible. Tell them you didn’t agree to a contract and that you might have been a victim of fraud. If the supplier has made a mistake they should be able to fix it for you.
If you’re a tenant you should check if your landlord has given your name to the supplier and told them you’ve moved in.
If you still think it might be fraud you should tell the police by using the Action Fraud website.
Action Fraud will give you a reference number, which you should keep.
Contact the Citizens Advice consumer service to work out if you have to pay the bill.
If you’ve moved house
What you have to pay depends on if the bill is for before you moved in, or after you moved out.
If the bill is for before you moved in
You don’t have to pay for energy that was used before you moved in.
Tell the supplier you moved in after the energy was used. You’ll need to:
tell them when you moved - if they ask for proof, send them a copy of your tenancy agreement or mortgage contract
ask them to send you a new bill
give them a meter reading to make sure the new bill is right
If the bill is for after you moved out
If someone else moved in after you, you shouldn’t have to pay for energy they used after they moved in.
If the bill is for after they moved in, tell the supplier. Tell them the date the other person moved in, if you know it. Ask the supplier to send a new bill to the person who lives there now.
If the other person didn’t move in straight away, you might still have to pay for some of the energy before they moved in.
If no one else moved in straight away
You usually need to pay for energy until 2 days after you told the supplier you were moving.
If you contacted the supplier the day before you moved, or after you moved out, you might have to pay for some energy after you moved.
If the bill is charging you for more than 2 days after you told the supplier, contact them. Tell them the date you told them you were moving. Ask them to explain why they’ve charged you for more than 2 days after that date.
If the supplier still says you have to pay the bill, you can contact the Citizens Advice consumer service to check if you have to pay it.
If you have to pay the bill
If you’ll struggle to pay, the supplier has to help you find a solution - find out how to talk to your supplier if you’re struggling to pay the bill.
If the bill is for somebody who has died
If you’re the ‘executor’ or ‘administrator’ you need to let the energy suppliers know about the death. You should also take meter readings and give them to the suppliers.
The executor or administrator is in charge of handling the financial affairs of the person who has died. An executor is named in the will. The court appoints an administrator if there isn’t an executor.
Check how to deal with the financial affairs of someone who has died.
Energy used before the person died
If your name is also on the energy account you have to pay the energy bills. If you're unsure, check to see if your name is on the bill or contact the supplier.
If the person who died was the only name on the account, the supplier shouldn’t ask you to pay the bill - even if you're a close relative.
The executor or administrator pays the bills using money left by the person who has died. If they haven’t left enough money, the bills might not get paid.
Energy used after the person died
You need to pay if:
you’re living at the property
the property was left to you in the will - even if you’re not living there
You should contact the supplier and tell them to put the account in your name.
If the bill is for somebody who has gone into care
They have to pay their energy bills and other debts if they're capable of making decisions. This is called having 'mental capacity'.
If the person in care has lost mental capacity a 'deputy' or ‘attorney’ will usually pay the bills for them. A deputy is somebody approved by the court to act for the person in care. It might be a family member. An attorney is somebody the person in care asked to act for them before they lost mental capacity.
Check how to become a deputy for somebody who has lost mental capacity.
Energy used before the person went into care
You only have to pay the energy bills if your name is also on the energy account. If you're unsure, check to see if your name is on the bill or call the supplier. The supplier shouldn’t ask you to pay the bill of somebody who has gone into care - even if you're a close relative.
If you're the deputy or the attorney, you can use the money of the person in care to pay the bills. You should also let the suppliers know and cancel contracts if necessary. You don't have to pay for anything yourself.
Energy used after the person went into care
If you’re living at the property, you need to pay.
You should contact the supplier and tell them to put the account in your name.
If you think the bill is for the wrong meter
You can check if your meter is the same as the meter on the bill.
Check your gas meter
You can find out if the gas meter on your bill is correct by comparing the Meter Point Reference Number (MPRN) on your bill with the MPRN registered to your address. The MPRN is a unique registration number for your meter.
Find your MPRN on the Find My Supplier website.
If the MPRNs don’t match you should contact your gas supplier.
If the MPRNs match but you’re still worried the bill is wrong, you can compare readings. Check the reading on your meter and compare it with the reading on the bill. If there’s a big difference you should contact your supplier.
Check your electricity meter
You can find out if the electricity meter on your bill is correct by comparing the Meter Point Administration Number (MPAN) on your bill with the MPAN registered to your address. The MPAN is a unique registration number for your meter.
First, you need to find who your electricity network operator is. This is different from your electricity supplier. Find your electricity network operator on the Power Cut 105 website.
When you've found your electricity network, use the ‘Find my supplier’ service on their website. It will also tell you the MPAN for your address.
If your network operator is:
National Grid - check your supplier on the National Grid website
Scottish and Southern Electricity Network - check your supplier on the Scottish and Southern Electricity Network website
Northern Powergrid - check your supplier on the Northern Powergrid website
Electricity North West - check your supplier on the Electricity North West website
SP Energy Networks - check your supplier on the SP Energy Network website
UK Power Networks - check your supplier on the UK Power Networks website
If the MPANs don’t match you should contact your electricity supplier.
If the MPANs match but you’re still worried the bill is wrong, you can compare readings. Check the reading on your meter and compare it with the reading on the bill. If there’s a big difference you should contact your supplier.
If you pay your landlord for energy
You don’t have to pay the energy supplier as well.
Tell the supplier you’re not responsible for paying the bill. They should send the bill to your landlord instead.
If you’re not sure whether your rent covers energy bills, check your tenancy agreement. If you don’t have a copy of the tenancy agreement, ask your landlord for a copy.
If you can't agree with your landlord about who pays the bills, you can get advice from the Citizens Advice consumer service.
If you think your landlord is overcharging you for energy
If you’re worried that you’re being asked for too much money, check what your landlord can charge you for energy.
If someone won’t pay their share
You’ll usually have to pay the whole bill and try to get the money back from them afterwards.
If you’ll struggle to pay the bill, your supplier has to help you find a solution - find out how to talk to your supplier if you’re struggling to pay the bill.
If the other person won’t pay their share, you could take legal action against them - called ’making a small claim’. Legal action can be expensive and stressful, so you should decide if it’s worth making a small claim before you start.
