Key steps for tackling catch-up energy charges

CHECK your bills – paying close attention to dates of usage.

CONTACT your supplier first if you have been sent a sudden catch-up bill for energy used more than 12 months ago. REMIND your provider of their obligations under the back-billing rule.

GET help if your supplier has not fixed the problem satisfactorily within eight weeks. You can refer your case to independent complaints services such as Resolver or Ombudsman Services. Visit resolver.co.uk or ombudsman-services.org/energy. You can also call the latter on 0330 4401624.

FIND more on the back-billing rule at ofgem.gov.uk and citizensadvice.org.uk. Or call Citizens Advice on 0345 404 0506.
