FAQs - Switching supplier, tariffs and bills
- Can I switch tariff or energy supplier if I have a smart meter?
Yes. People with a smart meter can switch energy supplier and tariff in exactly the same way that anyone with a traditional meter can. Find out more about switching supplier with a smart meter here.
- Do smart meters work with prepay?
Yes. Smart meters will make prepay as easy as pay-as-you-go on your mobile or tablet. If you choose smart prepay, you should be able to conveniently see how much credit you have left on your in-home display, using an app, over the phone, or via text. Top-up in person at your local store/outlet, without any need to put a key or card back into a meter. Payments will automatically be added to your account and you'll always be able to top-up with cash. Pay the same rates as everyone else - smart meters will remove the need for prepay to be more expensive than other tariffs. Switch between payment modes (credit and prepay) without physically changing your meter.
- Can I get a smart meter if I am on an Economy 7 or an Economy 10 tariff?
If you have an Economy 7 or 10 electricity supply, you can get a smart meter as part of the national rollout. But it does depend on which energy supplier is ready to install one for you. Smart meters of this type will be available at a larger scale later in the rollout.
- How accurate are smart meters?
Smart meters are as accurate as traditional meters. By law, all smart meters have to be approved by and certified by the Office of Product Safety & Standards to prove their accuracy. If you believe that there's a fault with your smart meter you can report it to your energy supplier in the same way you do now.
- Will the in-home display cost me anything to run?
Your smart meter's in-home display will cost less than £1 a year in electricity.
- Does a smart meter mean my energy can be cut off more easily?
No. You're protected by strict regulations against your energy supplier switching off or disconnecting your gas or electricity supply. This protection remains as strong with smart meters as it is with traditional meters.
- Will I still be sent energy bills?
Yes. Your in-home display is for information only. You will still receive regular energy bills in the same way you do now, whether that's in the post or online, but now they'll be accurate, without you having to submit a manual meter reading. Depending on your energy supplier, you may also receive some energy efficiency advice.
- Can my smart meter help me save money?
Yes. Smart meters can help us to identify situations where we're using a lot of energy and might want to make changes to this. If you use the information shown on your smart meter in-home display to reduce your energy use, you could reduce your energy costs. Smart meters also mean accurate bills as they bring an end to estimates, so you can be confident that you're only paying for what you've actually used.
- I have a smart meter so why is my supplier asking for a reading?
As with all wireless technology, smart meters may occasionally experience connectivity issues. Just like mobile phone or Wi-Fi networks, these problems can be caused by a number of issues that can usually be resolved quickly. If your smart meter cannot communicate with your energy supplier via the designated wireless network, they may ask you for a temporary manual meter reading so that your bills will remain accurate until the problem is resolved.
- I have a smart meter so why have I received an estimated bill?I have a smart meter so why have I received an estimated bill?
The first bill you receive after having your smart meter installed may still be estimated. If you are still receiving estimated bills after this, you should contact your energy supplier.
- Can I be charged different prices at different times of day?
No, an energy supplier cannot charge you based upon when you use your energy unless you specifically choose such a tariff (known as time-of-use tariffs). Time-of-use tariffs could mean lower bills if you use energy outside peak times. They will also help energy suppliers to better manage periods of peak demand. Time-of-use tariffs are not compulsory and if they suit your lifestyle, could save you money. There are already some time-of-use tariff such as Economy 7 and Economy 10, or even free energy at certain times of day, but smart meters mean that time-of-use tariffs can be more flexible.
