British Gas is the UK's largest supplier of domestic gas and electricity, making them the biggest of the big six. British Gas also offer home services including boiler cover and remote heating control systems.
uSwitch can help you find the best energy prices in your area — just follow these simple steps to compare gas and electricity:
uSwitch is a free, independent price comparison service that can help you compare energy prices and switch your gas and electricity supplier to save on your household bills.
We’re the most popular energy comparison site in the UK, but don’t take our word for it. We’ve helped more than five million people compare energy deals and save on their energy bills. Since 2006, uSwitch has been fully accredited by the Ofgem Confidence Code.
If you haven’t switched your energy tariff recently, it’s unlikely you’re on the best deal available. With uSwitch you could save up to £477 on your energy bills simply by switching.
There’s no one cheap energy supplier for everybody, so it’s important to run an energy comparison based on your details. That way we can help you find the best energy deals in your area and for your needs.
To find the cheapest gas and electricity deals you’ll need to shop around once your fixed plan has ended. After your plan’s end date you’ll likely be rolled onto a standard tariff, which is the most expensive type of plan.
If you’ve never switched or haven’t done so for a while, it’s likely you can find a cheaper energy deal in minutes with uSwitch. Simply enter a few details and search for a cheap energy deal.
You might not even need to switch away from your supplier to find a cheap energy tariff. Check to see if your current supplier has a cheap gas and electricity deal on offer — the cheapest energy supplier for you could be the one you’re already with.
The cheapest energy supplier for someone else isn’t necessarily the cheapest for you. That’s why we compare energy suppliers tailored to you to get the best energy deals.
Energy suppliers vary their pricing by region and your bill will also depend on your usage. Different energy suppliers also target different types of household, so some might offer a cheaper deal to a family home with high usage, while someone living alone with low usage might find a cheaper energy deal with a different supplier.
We only work with trusted energy suppliers and run a yearly customer satisfaction report so you can see how each supplier performs in a wide range of categories from customer service to value for money, green services to smart meter installation.
Not all households use both types of energy and many energy suppliers offer tariffs for just one type of fuel. You can also compare gas and electricity separately if you wish to choose different suppliers for each instead of using a dual fuel tariff.
In Great Britain, around 4 million households do not use mains gas for heating. Just over half of all non-gas households use electricity as their primary heating source (Ofgem).
If you don't require a gas tariff for your home, you can search for separate electricity-only tariffs. When comparing energy prices with uSwitch, we'll ask if you use gas in your home. If you answer no, we'll show you electricity-only tariffs that could save you money.
If you use both gas and electricity but want to compare tariffs from different suppliers, you can choose to see these separately by choosing 'show me electricity plans' on your results page.
While most households use electricity and will require both an electricity and gas plan, you can also choose to have separate suppliers or tariffs for each fuel.
There are a number of gas-only suppliers and many standard energy suppliers also offer separate gas-only tariffs.
If you'd like to compare gas tariffs with uSwitch, simply run an energy comparison and select 'show me gas only plans' on your results page. You'll be able to easily compare gas-only plans and dual-fuel tariffs to see which is the best energy deal for you.
There are four easy ways to compare energy deals with uSwitch — and all of them are completely free:
For us to run an energy comparison, we’ll need your postcode and address details as well as a recent energy bill. If you don’t have a bill you can just tell us how much you pay for your gas and electricity. If you don’t know how much you pay we can estimate your usage based on a few extra details. To complete your switch you’ll need to provide contact and payment details so your new supplier can take over your energy account.
uSwitch is a free service that handles the switching process for you. Once you’ve completed your energy switch, your new energy supplier will contact your old supplier and agree a switching date. You will then receive a welcome pack and letter from your new gas and electricity supplier. This will outline what you’ve agreed to, and tell you what happens next. There won’t be any interruption in your energy supply.
It only takes a few minutes to run an energy comparison with uSwitch. Once you’ve confirmed your switch with us, there’s a 14-day cooling-off period in which you can cancel your switch if you change your mind. The whole energy switching process should be complete in 17 days.
Your gas and electricity bills are largely dependent on usage, but there are other reasons your bills might have gone up recently:
Your fixed price plan ended
A fixed price plan protects against price rises. These plans do end though, and when they do you get automatically rolled on to a new plan with different rates. This is often a standard variable tariff or default tariff, the most expensive type of plan on offer.
Your energy supplier has raised prices
If you’re on a standard variable or default tariff, your energy supplier can raise prices at any time. In 2019, many energy suppliers raised their prices in reaction to an increase in Ofgem’s energy price cap.
Your bills are based on estimated meter readings
Check that your bill is based on actual readings of your electricity meter rather than estimated ones. It’s important to take your own readings so that you get charged accurately. Or consider getting a smart meter, which provides real-time meter readings and can help you monitor your energy usage — you can request one from your supplier or switch to a smart meter tariff.
Yes, you can switch your energy deal if you’re on a prepayment meter. Just select ‘Prepayment meter’ when you’re asked how you pay your energy bills. You can tell you’re on a prepayment meter if you pay in advance with a smart card, token or key. You can also choose to switch away from using a prepayment meter by replacing it with a credit meter.
Yes, you can switch to a better energy deal if you’re a tenant. The only exception is if your landlord pays the energy bills or if energy charges are included in your rent. If your name is on your energy bill you have the right to switch energy supplier and save on your bills.
Once you’ve run an energy comparison you’ll be able to choose from available tariffs, which could include fixed rate contracts or variable price tariffs. Fixed rate contracts usually last between 12 and 24 months and guarantee the rate you pay for your energy during this time. Variable price tariffs can go up or down depending on wholesale energy prices.
It’s important to note that this is different from a standard variable tariff, which you’ll usually be switched to after your fixed rate ends. Standard variable tariffs are usually a supplier’s most expensive plan so it can pay to shop around if you’ve been rolled onto this type of plan after your fixed rate term has ended.
The best gas and electricity supplier for you won’t necessarily be the cheapest. You can use uSwitch to filter by what’s important to you, whether that’s a large supplier or one that offers green energy plans.
We also know customer service is important, so we’ve assigned each supplier star ratings based on our energy customer satisfaction report to help you compare energy suppliers, from the well-known ‘big six’ to the smaller suppliers you might not be so familiar with.
If you don’t want to switch away from your supplier, you still might be able to find a better deal with uSwitch. If you haven’t switched your energy deal before it’s likely that you’re on your provider’s standard variable or default tariff, which is typically the most expensive type of plan on offer. You can use uSwitch to switch to a better energy deal from your current provider if you’re happy with the service but want to save on your energy bills.
There are more gas and electricity suppliers on the market than ever before. It can feel overwhelming trying to choose the right energy deal for you but uSwitch makes it simple.
We provide customer ratings for more than 30 suppliers. These ratings are based on responses from more than 17,000 energy customers in 2019 as part of uSwitch’s independent YouGov survey.
To view all 2019 customer ratings, visit our dedicated energy customer service page.
uSwitch 2019 customer ratings are based on an independent YouGov survey that was conducted between 6 November and 27 November 2018. A total of 17,159 UK energy customers were asked to rate their energy supplier on overall satisfaction, transfer process, value for money, customer service and how likely they were to recommend. We equally weighted those five scores across suppliers with at least 50 responses to create an average supplier rating for each.
* This supplier had fewer than 50 responses in our independent YouGov survey, which is not enough data with which to provide a customer service rating.
