There are two types of gas and electric smart meters used in homes across the UK. The first is a credit smart meter which keeps a track of usage and then uses this data to issue a bill to the contract holder. The other is a pre-paid smart meter which requires credit to be put into it and then issues gas and electricity based on these existing funds. This is called topping up.

The coronavirus pandemic is likely to affect all of our personal finances. However, the UK lockdown will not affect the services we provide. Our team of experts are working hard to ensure that you make savings on your energy bill by switching suppliers. Read more about your energy supply during COVID-19 here.

Pre-paid meters are used for a variety of different reasons. These include:

  • You don’t get any bills
  • You are in control of how much you top up
  • You don’t build up debt
  • You can see your remaining balance on screen

However, if you’re used to a credit meter or have never used a pre-paid meter before it can be a little confusing. This guide aims to inform you of everything you need to know about topping up your meter.

How do I top up my electricity and gas smart meter?

Before you top up for the first time, you’ll need to activate your card. You do this by putting your card (which you get from your supplier) into the meter for at least a minute. Once activated, you need to take your card to a convenient Payzone or Post Office where you can top up credit. Once back home, put your card in the meter and it will transfer the credit ready for use.

It may also be possible to set up an online account so that you can top up online. You’ll need to check with your supplier if this is a service that they offer. Most modern smart meters allow this kind of functionality.

How do I top up a smart meter manually?

If you do not have an online account then you will need to top up your smart meter manually. You can do this at your local Post Office but you will generally need to top up by at least five pounds. Often you will need to top up to the nearest pound.

As well as the Post Office, you can also top up anywhere you see a Payzone sign. These can be located in newsagents, supermarkets and garages. Just look out for the Payzone logo.

How do I top up my meter online?

If you have a prepaid smart meter and your provider allows you to top up online, you will need to go to their website and locate the top up area in the menu. Or they may have an app which you can download to your phone to take you straight to the top up area.

If it’s your first time, you may need to register your account and bank details. Once this is done, you can top up in seconds from anywhere you have an internet connection on your phone. Simply choose your top up amount, click confirm and your meter will be automatically credited.
