1. First, carry out a price comparison to see how your existing tariff compares. Use the UK Power Price Comparison Service by entering your postcode, existing suppliers, and amounts paid, to obtain a complete list of prices available in your region.

2. Review the list and see how your existing suppliers compare with the others.

3. If you are still with your original separate suppliers you may find that you can save by switching to dual fuel with either one of them. You may be able to save more by switching to a another supplier.

4. When you are ready to switch, use the links from the comparison results pages, or the links listed on the Suppliers page.

At this stage you may need to have your existing meter identification numbers available - MPAN for electricity, and MPR for gas. (See FAQ about Meter Numbers). These numbers need to be exact and accurate.

5. When you arrive at the application form, complete all information requested and submit the form.

The application forms which are linked to the results pages can, in most cases, automatically validate your address and gas and electricity meter numbers. On occasion it will request that you manual enter the required information.

The suppliers application forms that are listed on the Suppliers page will require full name, address and meter reference numbers to be entered manually.

6. Contact your existing suppliers by telephone or letter to let them know you have activated a transfer.

7. Wait until you receive communications from the new supplier and the existing supplier, with further instructions. At some stage you will be asked to provide meter readings which will be used by both suppliers to prepare final and opening bills.
