Key protections that often apply in this sector. Always check the latest official guidance.
EDF holds a domestic energy supply licence and must handle complaints in line with Ofgem's Standards of Conduct. They must treat you fairly, investigate your complaint properly, and give you a clear outcome. If they fail to do this, it strengthens your escalation case.
Gas Act 1986; Electricity Act 1989; Ofgem Standards of Conduct
Ofgem rules generally prevent domestic suppliers from back-billing you for more than 12 months of energy use where the supplier was at fault for not billing you correctly. If EDF sends you a large catch-up bill, check whether this rule applies and challenge it with evidence of when the billing error began.
Ofgem back-billing rules
EDF must meet Guaranteed Standards of Performance, which require automatic compensation payments for certain service failures such as missed appointments, supply interruptions beyond set time limits, and delays in making connections. Check Ofgem's website for the current compensation amounts.
Guaranteed Standards of Performance
Energy is a service under the Consumer Rights Act 2015. EDF must supply energy with reasonable care and skill and match any descriptions given to you. If you were promised a specific tariff or rate and EDF failed to deliver, this legislation supports your complaint.

Typical stages for UK consumer complaints in this sector.
Contact EDF through their official complaints channels. State clearly that you are making a formal complaint, not a general enquiry. Get a complaint reference number and note the date, time, and name of the adviser. If you call, send a follow-up email confirming what was discussed.
If your complaint is not resolved promptly, send a written follow-up by email or letter. Attach bills, meter readings, screenshots, and any correspondence. State clearly what outcome you want and give EDF a reasonable deadline to respond.
If EDF cannot resolve your complaint, ask for a written final response or deadlock letter. This document, or the passage of 8 weeks from your original complaint, unlocks your right to escalate to the Energy Ombudsman.
Submit your case to the Energy Ombudsman with a clear timeline, all evidence, and your desired outcome. The service is free. The ombudsman can order EDF to correct bills, pay compensation, and take specific action. Their decision is binding on EDF if you accept it.
Incorrect bills based on estimated readings, unexplained charges, bills that do not match actual usage, and discrepancies between smart meter displays and billed amounts.
Installation delays, meters losing communication with EDF, inaccurate readings after installation, and in-home displays that stop working or show incorrect data.
Monthly payments set too high, refusal to reduce payments when the account is in credit, delays in refunding credit balances, and unexpected increases without clear explanation.
Being moved to a more expensive variable rate without adequate notice, confusion about fixed-rate end dates, and exit fee disputes when trying to switch.
Long phone queues, complaints not being properly logged, different advisers giving contradictory information, and promises of callbacks that do not materialise.
Inadequate support for customers in financial difficulty, failure to offer affordable payment plans, and not properly identifying or supporting vulnerable customers as required by licence conditions.
