Key steps for customers who want to change their deals

DO not be deterred from finding a better tariff, even if the list of new entrants seems overwhelming. If you decide only to opt for a familiar brand name, a cheaper tariff is still likely to be available – especially for those who have never switched or have not for a while.

USE a comparison website such as TheEnergyShop, uSwitch or comparethemarket to find a new deal. For further guidance about how to switch visit citizensadvice.org.uk/energy.

READ customer opinions about individual suppliers before switching. You can get an idea of gripes and concerns on review website Trustpilot.

CHECK whether a company asks for money upfront before it has even taken over your energy supply. This is an indication of a company being hungry for customers’ money because it has limited financial backing, which you may not be comfortable with.

ASK whether a supplier offers the Warm Home Discount. If you are on a low income or receive the ‘Guarantee Credit’ element of Pension Credit you are eligible for a £140 discount on your electricity bill. You can see a list of energy companies signed up to the discount scheme at gov.uk/thewarm-home-discount-scheme.

WAIT a short while if you are being transferred to a new energy company because yours went bust. Delay comparing and switching until your account has been moved and the dust has settled.

REMEMBER the Energy Switch Guarantee. It is free and ensures your new provider takes all responsibility for the switch within 21 days. This time-frame will in future be reduced to just one day.

The old provider must send a final bill no later than six weeks after the switch and any credit owed must be refunded no later than 14 days after that. To find the list of participants in the guarantee, visit energyswitchguarantee.com/signatories.
