Switch energy — your switching questions answered

What is uSwitch?

uSwitch is a free, independent price comparison service that helps consumers compare gas and compare electricity prices and switch energy supplier to save money.

Will my gas or electricity supply get cut-off during switching?

No. You'll still be receiving your energy through the same pipes and cables so there won't be any an interruption to your electricity or gas supply, or any need to dig up the road. Only the company that provides your gas bills or electricity bills will change. Or, if you compare gas and electricity, your dual fuel bills will change.

How do I compare gas and compare electricity prices?

Start by entering your postcode on our site and follow the instructions on-screen to compare energy prices, or just gas or electricity. We’ll provide you with a list of suppliers and how much you could save.

But I just want to compare cheap electricity prices or cheap gas prices.

There's no one cheap provider, but there is the cheapest for you. We will show you the cheapest energy suppliers in your area, but we need your basic information to provide an accurate energy comparison.

What happens once I've switched energy?

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 & electricity supplier. This will outline what you've agreed to, and tell you what happens next. There won't be any interruption in your gas and electricity supply.

What do I need to get started?

Your postcode and your latest gas and electricity bill. Having your latest energy bill will help you give us accurate information about your gas and electricity usage.

Don't worry if you don't have one handy though — we can work out your gas and electricity usage by asking a few extra questions.
