If I have a smart meter, can I change supplier?
Yes, you can change energy supplier with a smart meter. Changing energy supplier with a smart meter works the same as with a traditional meter. The same is also true for changing tariffs.
In fact, with a second-generation smart meter, you should be able to switch energy supplier without any interruption to your energy readings or bill payments.
So, with a smart meter, you can change your supplier as easily as you did before. But you will also get all the benefits of having a smart meter. For example, you can use a smart meter to find ways use less energy thanks to the handy in-home display.
I have an older smart meter – can I switch supplier if I have a smart meter that is older?
Older, first-generation smart meters sometimes lose some functionality after switching energy suppliers. If you have an older smart meter, also known as SMETS1, it might lose some functionality for a short time if you change supplier. If your meter does lose functionality, it’s important to know that this is a temporary situation and your meter will still be accurately measuring your energy use.
First-generation smart meters are being migrated into the new secure smart data network.
This will happen 'over the air', without needing a visit from an installer. These smart meters will then be able to deliver all the benefits of smart, with any supplier. The process to migrate the first-generation meters is progressing well. It is due to be completed by the end of the smart meter rollout. Your energy supplier may be able to tell you more about their plans for this and how long it will take.
Overall, none of this affects your ability to switch your energy supplier. Even if you have an older smart meter, switching energy suppliers won’t affect your smart meters’ ability to measure your energy. So, you can go ahead and change your gas or electricity supplier.
Can I change supplier with a smart meter that is from the second generation?
Second generation (SMETS2) meters will keep their full smart functionality following a switch. The issue with switching only relates to some first generation (SMETS1) meters. Those SMETS1 meters will be remotely migrated into the secure smart data network. This means they will be able to seamlessly switch between suppliers.
Most suppliers are now offering second-generation smart meters to their customers. The majority of customers requesting a smart meter now get a second-generation meter. When you request yours, you can contact your supplier to find out what they can offer you!
Unsure what type of smart meter you have?
You may be wondering which type of smart meter you have, so you can plan your energy supplier switch. You can check if you have a smart meter in your home, and what type it is (first-generation or second-generation) using the links below – no need to contact your energy supplier:
What happens to smart meters when you switch supplier and tariff?
If you have a smart meter, the process for switching suppliers is the same as it is if you have a traditional meter. You don't need to get new smart meters if you switch suppliers or tariffs. Your smart meter will continue working with your new energy supplier. You also don't need a new in-home display either. The in-home display that came with your smart meter should still connect to your smart meter, even if you change supplier or tariff.

It’s simple with a smart meter. Change suppliers as you like:
The process for changing your energy supplier should be the same, regardless of what kind of meter you have. The new energy supplier you have chosen will manage the switch. You will likely need to provide your new supplier with information, such as your postcode, the name of your supplier, and information about your current tariff.
See Ofgem’s guide to switching energy supplier for more information.
You will not need to get a new meter when you change suppliers, apart from in very specific circumstances, such as if your old meter needs replacing, or you need a specific type of meter for your new tariff that is different from your current meter.
How can you get a smart meter if you don’t already have one?
Request a smart meter from your supplier. You can use the box below to find your supplier.
Once you've requested your smart meter, you will get a reminder of your installation date and time. Then, a trained professional will come round to your home to start the installation. For more information, read our smart meter installation guide.
