Protect yourself from energy scams and cold-calls

Mae’r dudalen yma ar gael yn Gymraeg.

Beware cold callers who say they’re from ‘Ofgem’ and suggest you switch supplier, then ask for your bank details. 

We’d never ask for your bank details and we wouldn’t cold call you, or come to your house. 

Ofgem is working with energy suppliers to trial ways of encouraging consumers to switch energy supplier. This involves suppliers contacting their customers on Ofgem’s behalf – this could be in the form of an Ofgem-branded letter, but will never be by telephone. 

If you receive a letter from your supplier with our branding on it and have any questions, you can contact your own supplier to check it’s genuine. 

If you receive any calls asking for bank details, please report it to the police by calling 101. 

Steps to avoid a scammer

  1. Don’t respond to cold calls from ‘Ofgem’: we wouldn’t call you
  2. Don’t give out your bank details or your personal details: we wouldn’t ask for these
  3. Check email address: any emails to or from Ofgem will ALWAYS end for example
  4. Check letters for branding: we will always head letters with this brand
  5. If in doubt, shout: If you are in any doubt, then call Citizens Advice on 03454 04 05 06 or online.

The Citizens Advice consumer service gives free, confidential and impartial advice. You can get in touch with them for advice at any time.

If you think you've been scammed

If you have been a victim of a scam and have disclosed personal or financial details to the callers, you should report this directly to the police by calling 101.
