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.
When you’re choosing a new energy deal, think about whether to go for dual fuel (where you get both your gas and electricity from the same company) or separate tariffs (where you get gas from one company, and electricity from another). It’s worth checking both options, as the combined price of separate tariffs can sometimes be less than a dual fuel offer.
3. Customer service: When the only utility available has lousy customer service, nobody is surprised. They don’t even pretend to care – they know they have you over a barrel. With all these new players in town, however, it’s a slap in the face to be treated like royalty until you’ve signed on the dotted line and now they won’t even return your calls or the person on the phone can’t string three English words together or if he does speak English, he’s brand new and panicking trying to pull up your account information.
