Why change your energy supplier?

Switching energy suppliers is a proactive step many UK households take to gain more control over their home energy. It is about finding a deal that better suits your needs, whether that means lower prices, improved service, or a greener energy mix.

Seeking better value

Energy prices can fluctuate, and new tariffs are regularly introduced. If you haven't switched in a while, you might be on a Standard Variable Tariff that is no longer the most competitive. Comparing deals could reveal significant savings on your annual energy bill.

Improving customer service

Not all energy suppliers offer the same level of customer support. If you've experienced long wait times, unhelpful responses, or difficulty resolving issues with your current provider, switching can offer a fresh start with a company that prioritises clear communication and continuous assistance.

Finding greener tariffs

For many, the environmental impact of their energy consumption is a growing concern. Numerous suppliers now offer tariffs that source a higher percentage of their electricity from renewable generation, such as wind and solar. Switching to one of these tariffs allows you to support sustainable energy practices and reduce your carbon footprint.

How to change energy supplier: a step-by-step process

The process of changing your energy supplier is simpler than you might think, typically handled by your new provider.

Gather your information

Before you start comparing, have your current energy details to hand. You'll need:

• Your latest energy bill, which includes your current supplier, tariff name, and annual consumption (in kilowatt-hours for electricity and gas).
• Your Meter Point Administration Number (MPAN) for electricity and Meter Point Reference Number (MPRN) for gas. These are unique identifiers for your supply points and can be found on your bill.
• Your address and bank details for setting up a new Direct Debit.

Compare energy deals

Use an Ofgem-accredited comparison website to find tariffs from different suppliers. Input your current usage (or an estimate if you don't have a recent bill) to get the most accurate quotes. Pay attention to:

• Unit rates and standing charges: These make up the core cost of your energy.
• Contract length: Fixed tariffs lock in your rates for a set period, while variable tariffs can change.
• Exit fees: Some fixed tariffs charge a fee if you leave before the contract ends.
• Customer service ratings: Check reviews to gauge supplier reliability.

Submit your switch request

Once you've chosen a new supplier and tariff, you can submit your switch request. Your new supplier will handle the entire transfer process, contacting your old supplier and managing the necessary industry communications. You will receive confirmation of your switch and a projected start date.

Provide meter readings

Around the time your switch is due to complete, your new supplier will ask for a meter reading. This "opening read" ensures a smooth handover, allowing your old supplier to generate a final bill and your new supplier to start charging you accurately. If you have a smart meter, this reading may be taken automatically.

Confirm your switch

Your new supplier will confirm when your energy supply has officially transferred. From this point, you'll begin receiving bills from them. The entire process, from submitting your request to your supply starting, is designed to be quick and hassle-free.

Key things to know before you switch

Understanding your rights and the rules governing energy switches can help you navigate the process confidently.

Understanding the 5-working-day switch

Under Ofgem's Faster Switching rules, domestic energy supplier transfers must complete within 5 working days of your switch request being submitted and accepted. This means you won't be left waiting for weeks to move to your new provider. You can also request a later start date if that suits you better.

The 14-day cooling-off period explained

You have a 14-day cooling-off period during which you can cancel your new energy contract without penalty. This period begins from the moment you submit your switch request (when the contract is agreed), not from the date your supply actually starts. Since the switch itself takes up to 5 working days, your supply will typically begin well within this 14-day window.

Switching with debt or a prepayment meter

If you have a prepayment meter and owe your current supplier money, you can still switch. Under the Debt Assignment Protocol (DAP), you can switch suppliers with up to £500 of debt per fuel (electricity and gas) . Your new supplier may agree to take on this debt as part of your switch. If you have a credit meter and owe money, your old supplier may object to the switch if the debt is significant or long-standing.

Switching as a renter

As a renter, you generally have the right to choose your energy supplier, unless your tenancy agreement specifically states otherwise. If your landlord pays the bills directly, or if your energy is supplied through a communal system, then you may not be able to switch. However, in most cases, if you are responsible for paying the energy bills, you can switch to a supplier that offers better value or service.

What happens after you change supplier?

Once your switch is complete, a few things will happen to finalise the process and get you settled with your new provider.

Your final bill from the old supplier

Your previous supplier will send you a final bill, calculated using the meter reading taken on your switch date. If you were in credit, they should refund you; if you were in debt, you'll need to settle the outstanding amount. If you had credit with your old supplier, it does not automatically transfer to your new account; you will need to contact your previous supplier directly to arrange a refund.

Getting started with your new supplier

Your new supplier will begin billing you according to your chosen tariff. If you have a smart meter, they will connect to it to receive automatic readings. For manual meters, you'll typically be asked to submit readings periodically to ensure accurate billing. Many digital-first suppliers, like Fuse Energy, offer apps that simplify meter reading submissions and provide real-time usage data, giving you greater transparency and control over your energy.

Compensation for delayed switches

If your energy switch is delayed beyond the mandated 5 working days, you are automatically entitled to £40 in compensation from your new supplier. This payment should be made directly to your energy account or bank account. Further £40 payments can be due for other related failures, such as if the compensation is not paid within 10 working days.

Common questions about changing energy suppliers

Can I switch if I have a smart meter?

Yes, you can switch energy suppliers if you have a smart meter. Your new supplier will connect to your smart meter after the switch is complete, allowing for automatic meter readings and often providing access to more detailed energy usage data through their app or online portal.

What if I change my mind?

You have a 14-day cooling-off period from the day you agree to your new contract to cancel without penalty. If you decide to cancel within this period, simply contact your new supplier. If you change your mind after the cooling-off period and are on a fixed tariff, you may incur exit fees if you switch again before your contract ends.

How often can I switch?

You can switch energy suppliers as often as you like. There are no restrictions on how frequently you can change providers. However, be mindful of any exit fees if you're on a fixed-term contract, as these can make frequent switching uneconomical. Many customers choose to switch annually or whenever a better deal becomes available.
