Gas and electricity prices have continued to increase over the past few years - so if you've never switched supplier, you could potentially save hundreds of pounds a year on your energy bills.

Even if you have switched gas suppliers in the last couple of years you may still be able to save money on your gas bills - comparing gas suppliers with Which? Switch only takes a few minutes, and lets you see all the latest gas tariffs available.

What you'll need to compare gas suppliers

Comparing gas suppliers with a comparison service like Which? Switch is straightforward - here's what you'll need to hand:

Your postcode: your location affects which gas companies you can switch to, as suppliers differ according to geographical areas.
Existing gas supplier and tariff: we need to know which company and plan you're currently on, so we can calculate possible savings against the best deals of the market. You'll find this on your last gas bill, or by contacting your current gas supplier.
How much gas you use: again, potential savings will depend on how much gas you use. You can work this out by looking at the amount used on your last couple of bills, or get a rough estimation based on how much you pay for your gas each month.

Ways of comparing gas suppliers

Running a gas tariff comparison on Which? Switch takes a few minutes

Gas prices

Cheapest price your top priority? The cheapest gas deal for you will depend on how much gas you use, how you are billed and how you pay your bills. Some gas companies give discounts if you pay your bills by direct debit, manage your account online or don't receive paper bills. You can also get extra discounts if you take gas and electricity (dual fuel) from the same supplier.

Which? Switch customer satisfaction scores

As well as looking at price, you may want to consider how well a gas company looks after its customers. Our energy customer satisfaction survey is the largest of its kind in the UK and scores each energy company by the accuracy of its bills, phone and online customer support and dealing with customer queries.

Which? Switch tariff ratings

When you compare gas suppliers, we list our unique tariff rating next to each of your results. Our tariff ratings are calculated by combining customer satisfaction survey data with information about each tariff - for example, how long prices guaranteed to stay the same and whether tariffs are open to new and existing customers. We'll also list details such as how easy it is to switch to each supplier - see our tariff rating overview page for more.

After choosing a new gas supplier

Once you've chosen a new gas supplier, we'll provide it with your details to arrange your switch. You'll need to give your new and old gas supplier a meter reading. Your new gas supplier will use your existing meter and pipes, so no one will need to come to your house.
