Switch Energy Supplier

Before you start

Decide if you want to switch gas, electricity or both (dual fuel). You will need the following information to switch your energy supplier.

• For electricity, your Meter Point Registration Number (MPRN)
• For gas, your Gas Point Registration Number (GPRN)
• An up-to-date meter reading to make sure you are billed accurately

You can find your MPRN and GPRN at the top of the front page of your bill.

Step 1 – get your details

This information will help you get the best deal when switching. You can find it on your energy bill or by contacting your energy supplier.

• how much gas or electricity you are using now
• if you are an electricity customer and considering moving to a Time of Use tariff (associated with Smart Meters), it is a good idea to consider ‘when’ you use most of your electricity and choose a tariff that suits your usage profile
• the amount you pay now
• if you are on a fixed-term contract, find out when the contract ends. There are no charges when switching to a new supplier. But there may be a charge if you break a fixed-term contract.

Step 2 – talk to your supplier

Your current supplier won't want you to switch. They'll try to keep you as their customer and may offer you a better deal.

Before switching, ask your supplier:

• if they can offer you a better deal or price plan
• what discounts are available for existing customers

Step 3 – shop around

There are many gas and electricity suppliers looking for new customers.

To get the best deal you should:

• look at the price plans on offer from different suppliers
• use a free price comparison website to make shopping around easier

As well as the price you should think about:

• how you would like to be billed - paper or online?
• the payment methods offered
• if the new supplier applies early exit fees
• if you can get cash back or other incentives
• the level of customer service offered

Step 4 – choose

You've shopped around and decided what price plan and supplier suits you. You are now ready to:

• contact your chosen supplier
• confirm that you want to switch to them

If you are using a price comparison website, they'll do all this for you. Remember to tell your new supplier if there is a vulnerable customer in your household.

What happens next

When you switch supplier, there is a 14 day cooling off period. This means you have 14 days to change your mind and cancel the switch without any penalty. The Consumer Rights Act 2022 came into force on the 29 November 2022, this extended the cooling-off period for certain ‘distance’ or ‘off-premises’ contracts from 14 to 30 days.

Your supplier should never be pushy or rush you into a contract. Take your time and consider the offer carefully. Be sure to read the terms and conditions associated with the contract.

Once the cooling off period has ended:

1. The switching process is carried out through network market messaging with the Meter Registration System Operator (MRSO) within ESB Networks.
2. You will receive a welcome letter from your new supplier.
3. You will receive a final bill from your old supplier.
