Step 1. Our lowest prices online including a boiler service when you join us[1]

Or call us on:

Step 2. Once you've agreed a quote with us we'll send you a contract pack. You don't need to do anything with this; it's just for your reference.

Step 3. We will process your switch and contact your existing supplier for you. There's usually little for you to do if:

  • You're all paid up
  • You're not tied into your existing contract
  • You've allowed for your notice period
The switching process usually takes around 3 weeks. We'll keep you informed of the progress and your switch will be completed on an agreed date. There'll be no disruption to your business or its energy supply.

Step 4. Before we switch your supply, you'll need to give us a meter reading. You can do this via your online account. Remember, we'll still need this even if your existing supplier installed a smart meter as currently they can't send data to other suppliers.
