Energy prices are going down in April

Good news! On 1st April, the price cap set by Ofgem will fall. If you’re on one of our variable tariffs, or recently switched to our Price Promise tariff, your energy prices will be reduced.

There’s nothing you need to do. We’ll be in touch to let you know what it means for you.

Compare our energy tariffs

Energy tariffs are the set rates you pay to us for gas, electricity, or both. They come in two basic types: fixed or variable.

Which type of tariff best suits your home depends on:

  • How much certainty you want over the price you pay

  • Get an energy quote, choose a tariff and buy online
  • We’ll talk to your current supplier, and arrange your switch

  • If you have more questions, read our comprehensive how to switch energy supplier guide.

How long does it take to switch energy supplier?

It normally takes 3-5 days to switch suppliers. You’ll also get a 14-day cooling off period where you can cancel your switch without paying a fee.

Can I switch supplier if I have a smart meter?

Yes. If you have a smart meter, you can switch energy suppliers and change your tariff the same way that someone with a traditional meter can.

If you have the first-generation smart meter, you can still switch but you may have to give the meter readings yourself for a bit. With a second-generation smart meter, you should be able to switch energy supplier without any interruption to your energy readings or bill payments.

What information do I need to change energy suppliers or get an energy quote?

Having your recent electricity and/or gas bill to hand is useful. That way you can get a more accurate quote. If you can't find it, don't worry. All we’ll need to give you a quote is:

  • Your postcode
  • The type of house you live in
  • How many adults live in your home

Can I switch energy supplier if I rent?

You can change energy supplier if you rent your home unless your landlord pays your supplier for the energy you use.

Check your tenancy agreement if you’re not sure whether you’re responsible for paying for your energy.

Why do some British Gas tariffs require smart meters?

British Gas, like all other energy suppliers in the UK has been asked by the government to help install smart meters to customers across England, Scotland and Wales. With more smart meters across the country comes a smarter energy grid.

Some of our tariffs, like our Electric vehicle tariff need a smart meter so that we can charge you lower rates during off-peak hours.

Smart meters also let us offer new ways that customers can make savings by changing when they use energy. PeakSave is our new demand flexibility scheme that’s rewarding customers for making small changes to their regular routines. Using smart meters, PeakSavers can earn credit towards their bills by helping the grid to better balance demand for energy when it’s particularly high, or low.

How do I get British Gas to supply energy in my new home?

If you’re an existing customer, we make moving your energy supply to your new home simple and quick. Access our moving home page to see how it works.

If you’re new to British Gas, but your new home is supplied by us, you can set up a new energy account in your new home online.

What’s dual fuel?

A dual fuel plan is one where you get both your gas and electricity from the same supplier, on the same contract. Many customers find this a convenient way to manage their energy because you’ll only have one supplier to contact and use one website and/or app to manage your energy account. Read our duel fuel benefits guide to understand more how it works.

What is a standing charge?

A standing charge is a fixed daily amount of money that we add to your energy bill.

It’s a daily charge that helps cover the costs of keeping your home connected to the energy network, however much or little energy you use. It also goes towards helping vulnerable people.

Your daily standing charge amount might change depending on your tariff or chosen payment method.

Learn more about standing charges.

What’s PAYG / prepayment energy?

A Pay As You Go (PAYG) meter (sometimes called a prepay meter) works in a similar way to a pay-as-you-go phone. You top up the meter with credit to pay for your energy. Then as you use the gas and electricity in your home, the credit is used up.

You can switch suppliers with a prepayment meter. If you want to switch to British Gas, then it’s easy to get an energy quote for your prepayment meter.

Already with us? Read our help guide that explains how to use your British Gas PAYG meter.

How do I find out who supplies my gas and electricity?

To find out your energy supplier, you can use the Meter Point Administration Service’s online search tool. Simply enter your address and they can tell you who your supplier is.

For detailed information check out our handy guide.
