With Boost, you’ll enjoy the benefits of a dedicated Pay As You Go service, with energy products designed to make your life easier. It’s energy the way it should be.

Rest assured the move won't interrupt your supply, won’t affect the prices you pay, and won’t affect your meter(s).

No, you don't need to do anything. When the time comes for your account to move, we'll be in touch. And we'll stay in touch every step of the way. Your supply and prices won't be affected by your move. And you'll still enjoy the great service you're used to.

In order to make this as smooth as possible, we'll be moving accounts over the course of a few months. We’ll send you a welcome pack with all the information you need, including your start date. You don't need to do anything now, we will write to you when your move is complete.

Accounts and Services

You'll receive a new Boost account number in your welcome pack.

If you have a smart meter you can keep using your Spark payment card in exactly the same way. Even after we’ve completed your move. So you don’t need to worry about changing it.

If you’ve got a traditional Pay As You Go meter, you’ll be sent a new key or card, and a welcome pack with more information.

We’ll let you know when we’ve switched you from the Spark app to the Boost Top-up app.

It's a really simple change - download the Boost Top-up app from the Apple App Store, or Google Play. Then log in with the same email and password you used for the Spark app.

You can keep topping up as you normally do. If your account is in credit, or debit, the amount will be transferred when you move.
