Switch energy supplier
Includes changing your energy supplier if you pay the household bills, run a business from home, have a prepayment meter, moving home, or in debt.
Overview
Switching to a different energy supplier and moving to a new tariff could save you money.
If you pay the energy bill in your household, you can choose which supplier you want to supply energy to your home and which tariff. You will be put on a contract called a ‘domestic contract’.
If you run a small business such as a pub or restaurant, you can also switch suppliers. You must have a business energy contract. An energy consultant can help you switch, but they will charge a fee for this service. Read how to set up a business energy contract.
It should take up to 5 working days to switch your energy supplier. You can also ask to be switched over on a later date.
Small businesses run from home
If you run your business from home, you could have a domestic or business energy contract. You should check with your supplier which one you have.
A business that has fewer than 10 employees and turns over less than 2 million euros (approximately £1.8 million) is called a microbusiness. If you run your microbusiness from home, you will need a business energy contract. Read how to get energy for your business.

How to switch energy suppliers
When you have chosen a supplier and tariff you want to move to, you will need to give the supplier information that is on your energy bill. They will need:
- postcode
- name of current energy supplier or contract
- name of current tariff
- amount you pay for your energy per unit, this is shown in kilowatt hours (kWh) on your bill
- amount of energy you use each year
Your new energy supplier will contact you and tell you when they will switch your energy supply over to them. It can take up to five working days for households.
If your supplier does not complete the work within this time, you can Get compensation for problems switching energy suppliers. Businesses cannot get compensation.
New domestic contracts can be cancelled within 14 days if you change your mind, but most business energy contracts cannot.
If you want to move your electricity or gas supply to a fixed rate tariff
Energy prices can go up and down. A fixed rate tariff means that if energy prices go up, you will still pay the same price for each unit of energy you use. But if energy prices go down, the price you pay will be the same.
You should choose your energy tariff based on how much energy you use and your own circumstances. You may have to pay a fee, called an ‘exit fee’, if you switch tariffs or suppliers before your fixed rate tariff ends.

Repaying a debt
You can switch to a new supplier even if you owe money to your old supplier and have been in debt to them for less than 28 days. Your old supplier will add any money owed to your final bill.
You cannot switch if you have been in debt to your supplier for more than 28 days. You need to repay the debt first before moving to a new supplier or tariff.
Your supplier has to pay back any money they have charged for energy you have not used. Read about how to get help if you cannot afford your energy bills.
Repaying a debt with a prepayment meter
You can still switch suppliers if you have a prepayment meter, and you owe your supplier up to £500 for gas and £500 for electricity.
Support if things go wrong
If you get a welcome letter or final energy bill that you were not expecting, you may have been switched to another supplier without permission. This can happen when:
- a supplier has made a mistake, for example mixed up your address with someone else’s, called an ‘erroneous transfer’
- you were misled by a salesperson
You can also get £30 from either your old or new supplier if you did not agree to switch. Small businesses cannot get compensation, but you can complain about your energy supplier.
