Frequently Asked Questions

How does switching work?

Gas bill and money

The switching process is easy! Simply enter your postcode to find the cheapest gas and electricity tariffs in your area and then choose the tariff and supplier that suits you.

Next, fill in your name, contact details and payment details and confirm your switch to your chosen supplier. Once you have completed the process, your details will be passed securely to your new supplier who will handle the changeover from your current supplier.

You will receive an email confirming your switch and outlining the details of your new supplier and tariff.

How long does switching take?

You should receive a welcome pack from your new supplier within a few weeks and they will inform you of the switchover date.

Calculator and electricity

How are the prices calculated?

Our comparison calculator takes your current gas and electricity usage details or typical spending that you enter and compares it with tariffs for a wide range of UK suppliers to see who can offer you the best deals. The calculation takes into account a number of different factors including where you live, your energy usage, whether you have Economy 7, your preferred payment method and whether you are looking for a dual fuel or single fuel tariff.

Comparisons use the most up-to-date energy prices that are available and the tool is updated often within hours of a price change being announced, meaning that the results you see are as accurate as possible.

Does the quality of electricity or gas vary by supplier?

Regardless of the supplier, electricity and gas are always distributed by the same network operators, which ensure the quality and continuity of energy distribution. These network operators also provide technical services for meters as well as network troubleshooting.

Will there be a break in my supply when I switch supplier?

The change of supplier is automatic and your new supplier will handle everything for you. You will not have to change or amend your electricity meter and/or gas and the network and distributor remain the same. There is, therefore, no risk of losing your energy supply.

Can I change my mind if I am not satisfied with a supplier?

Offers of electricity and natural gas for individuals are all non-binding. The customer can, therefore, change the offer at any time without charge or notice.
