All you need to know about how to switch energy suppliers

Switching energy providers is much easier and quicker than you might think. Here’s everything you need to know about how to switch energy supplier, from finding out if it could benefit you to whether you can use the same meter. Here are the most frequently asked questions:

How do I switch energy suppliers?

There are two ways to go about switching. Both are very simple:

  1. If you have already decided which supplier you want to switch to. In this case, contact the new supplier and tell them you want to join on the tariff you’ve seen that suits you. You’ll need your postcode, name of current supplier and tariff plus your bank details if you want to pay by direct debit. The new supplier will do everything else for you. They’ll cancel your current supplier and do the switch for you. 

  2. If you are not sure which supplier would be better for you. In this case, you can do the whole process through a comparison website. You’ll need details about your current tariff, supplier and postcode so you can compare suppliers and tariffs and the website will switch your energy suppliers for you. 

How do I know if I should switch my energy supplier?

If you’ve never switched suppliers, or haven’t in a long time, you will probably be able to get a better deal if you switch. It’s worth checking by using a quote generator such as this one on the Skint Dad Blog. If the quote you get is less than you’re currently paying, and it’s offered by a different supplier, it’s time to switch. 

If you get a quote that is cheaper than you’re currently paying but it’s offered by your existing supplier, contact them to change tariff. If you’re an EDF Energy customer, log into MyAccount to find the best tariff for you. Or, show us your bill to find out if you could save money on your energy bills.

Sometimes if you’re on a fixed rate tariff, there’s an exit fee if you cancel early so before you switch, check if you’ll incur a charge with your current supplier by cancelling your energy deal. 

How long does it take to switch energy suppliers?

This varies. Generally you should be all switched over within 2-4 weeks. It takes this long because there’s a 14-day cooling off period, then your new supplier will contact your old supplier and they agree a switch over date. Your new supplier will send you a welcome pack with information about your new tariff and your old supplier will send you a final bill. 

Will there be any disruption to my energy supply?

No. You won’t be cut off when you switch suppliers. On the day of your switch, you won’t notice any changes. 

What are the benefits of switching energy supplier?

Switching can offer you more control over your energy through evaluating different tariffs and suppliers so you can choose the best deal for you. You could get cheaper gas and electricity by switching energy suppliers. It’s worth comparing tariffs and suppliers so you know you’re on the best deal for you.

Can you switch energy suppliers if you have a debt?

This depends how long you’ve been in debt for. If you’ve been in debt for 28 days or less, you can switch. If it’s over 28 days, you’ll need to pay the money back before you can switch. 

Can you use the same meter?

Yes. You don’t need a new one, or for an engineer to come to your home. Easy. If you have a smart meter, it’s best to check with your new supplier as switching when you have a smart meter may make the meter lose its smart functionality. 

What should I consider when choosing a new energy supplier?

There are four main questions you should ask yourself when considering a new energy supplier:

  1. Do you like the supplier? Customer service is important when it comes to energy, so you should choose a supplier that you feel offers the support you need. 

  2. What kind of meter do I have? This is useful to know because some tariffs work best with certain meters. 

  3. What are the terms and conditions? Read the small print and check if there are fees involved in call-outs, cancelling your tariff or late payments. 

  4. Does the tariff represent your lifestyle? Choose a tariff that will be the best value for when and how you use your household energy. For example, there’s no point choosing an Economy 7 tariff that makes your energy cheaper at a certain time of day if you won’t be at home when the energy is the cheapest.

I rent my property, can I switch energy suppliers or does my landlord?

Whoever pays the energy bills is responsible for switching. If you pay the bills in your rented property, it would be good to check with your landlord first, but it’s your money so ultimately it’s your choice. 

Will I have an overlap where I’m paying for both tariffs?

As long as you provide correct meter readings when you switch, you won’t pay any more than you owe. Your old supplier will give your readings to your new supplier. If your new supplier asks you to pay a month in advance, you may get overlap in payments. You should check the details of your tariff to see if this applies to you.
