Only variable rates are changing, so check our fixed tariffs and get protected against price rises. And, if we bring out an even better fixed tariff later – you can swap for free.
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
- How often you want to switch supplier or change tariff.
If you need more help understanding energy tariffs, check out our fixed vs variable energy tariffs guide.
Fixed energy deals
A fixed tariff can offer peace of mind, as you’ll be protected from any future gas and electric price rises for the length of your tariff.
Fixed energy tariffs
Could be best if you:
- Want a fixed price for the length of your contract
- Pay by Direct Debit or on receipt of your bills
- Understand exit fees apply if you leave us
Electric vehicle tariffs
Works if you:
- Want an EV tariff designed exclusively for EV drivers
- Mainly charge your EV during off peak-hours (from 12am to 5am)
- Have a smart meter - or okay to get one installed
Dimplex Quantum tariff
This tariff works well if you:
- Have Dimplex Quantum storage heaters
- Want a cheaper night rate to charge your Dimplex Quantum storage heaters
The Ofgem price cap doesn't apply to fixed energy tariffs.
Variable energy deals
Energy costs can increase or decrease depending on the latest energy prices. The price cap is currently reviewed every three months, so the gas and electricity prices you pay will change regularly.
Standard Variable tariff
Choose if you:
- Want a contract with no end date or exit fees
- Pay by Direct Debit or on receipt of bills
- Understand your energy costs can increase or decrease
Safeguard PAYG
Our prepayment tariff could suit you if:

Frequently Asked Questions
How do I switch energy suppliers?
If you switch to us, we want it to be easy and hassle free. It normally takes just 3-5 days to switch to British Gas. Here are the three easy steps to switching energy supplier:
- Get an energy quote, choose a tariff and buy online
- We’ll talk to your current supplier, and arrange your switch
- We’ll let you know when your switch is complete and when we need your first meter reading(s)
- 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
- Your house number or name
- Whether you want a quote for single or dual fuel
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 energy 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 energy rates during off-peak hours and lower your bills.
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. Find the best dual fuel tariffs and understand more about 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.
