How an energy complaint should progress
Complain to the supplier first and keep a clear timeline of bills, readings, payments and responses.
Complain to the supplier first
Set out the account, bill or service issue with dates, meter evidence and requested remedy.
Ask for a deadlock position
If the complaint stalls, ask the supplier to explain its position or issue a deadlock letter.
Escalate after eight weeks
If unresolved after eight weeks or after deadlock, consider the Energy Ombudsman if the issue is in scope.
Keep meter photographs, bills and account statements because they often decide the dispute.
