Can I switch suppliers with a prepayment meter?

If you’re currently with another supplier and have a prepayment meter, you must join British Gas on Pay As You Go to avoid problems with switching your supply. If you’d like to change to a credit meter, we may be able to help once we’ve started supplying your home.

If you rent your home, you can switch supplier as long as you’re paying the energy bill.

You can switch supplier if you’re on a Pay as You Go (PAYG) meter, unless you owe more than £500 for gas or electricity.

What’s a prepayment energy meter?

If you have a prepayment meter (also called a Pay As You Go meter) you pay for your gas or electricity before you use it. You do this by topping up your meter using a gas card or electricity key at a local Payzone or Post Office. If you have a smart meter, there are a few more topping-up options.

When you use gas or electricity, your meter will use up your available credit until it runs out - you’ll then need to top-up again.

What's a smart prepayment meter?

A smart prepayment meter, also known as a smart Pay as You Go (PAYG) meter, offers convenient ways to manage your energy:

  • Online Top-Up
    Easily top up your meter online through our website or app.
  • Over the phone
    Top up on our automated telephone line, with no need to queue to speak to anyone.
  • Smart Card
    Use your smart card to top up at local Payzone outlets or the Post Office.
  • Real-Time Usage
    With a Smart Energy Monitor, track your energy usage in real-time. So you know when to turn down or switch off your home’s devices to make savings.
  • Effortless future top-ups
    Save your debit/credit card details in your online account, and top up in in just a few clicks.

If you haven't yet upgraded to a smart meter, ask us to install one after joining us.

What are the pros and cons of a prepayment (Pay As You Go) meter?

The pros

  • You can have control of how much and how often you top-up
  • As you pay for your energy before you use it, you won’t get a big bill at the end of the month or quarter
  • Your meter shows how much credit you have left, so you can stay on top of your spending

The cons

  • If you don’t top-up your meter up with enough credit, you won’t have gas or electricity
  • You’ll need to top-up more in winter, when the weather is colder and it’s darker
  • You need to make sure there’s always enough credit on the meter to cover standing charges, even when you’re on holiday, for example

Frequently Asked Questions

How much is the standing charge on a prepayment meter

As well as paying for any gas and electricity you use, you’ll pay a daily fee for being connected – this is called the standing charge. You pay this with a standard meter too. When you're on prepayment you need credit on your meter to pay it - even on days you don’t use any gas or electricity.  

The amount of the standing charge you pay will depend on where you live and what energy tariff and supplier you have.

Are prepayment meters more expensive?

Since July 2023 all prepayment customers saw their energy prices lowered to match the costs of paying by Direct Debit. This was introduced by the UK Government, and saves a prepayment energy customer around £21 a year (Source Government website). We brought forward this price reduction in April 2023 for all our Pay As You Go customers, so they started saving earlier.

What if I can’t top up?

Most meters warn you when your credit falls to £2. If you can’t afford more credit or are unable to top-up, our meters provide £10 of Emergency Credit for gas or electricity. We also offer Friendly Credit on conventional electricity key meters and smart meters during certain period - mainly overnight, weekends and English Bank Holidays. This means that if you accidently run out of credit, the meter won’t cut you off during these periods.

Using Emergency Credit

Do I need to submit meter readings?

No - if you're on Pay As You Go your readings are sent to us each time you top up.

Can I change my meter type?

If we supply your energy and you qualify, we can change your meter from Pay As You.
