We don't yet know how EDF's phone menu is structured, so we're not going to guess. If you work it out, we'd like to hear from you.
Before you call
What to know first
There is no residential number for leaving EDF. EDF say the new supplier contacts them automatically when you sign up, and you do not need to tell them yourself. They publish a “leave EDF” page for business customers; there is no residential equivalent. The number below is for tariff questions, exit fees and complaints.
Ignore the £25 exit fee figure you will find quoted. It appears across comparison and guide sites; it appears nowhere on EDF’s own website. Their published position is that it varies and lives in your Tariff Information Label. Unverified
EDF is more open than most about rates — they run a Tariff Information Labels hub with regional standing charges and unit rates on their own domain. Link to the hub rather than a dated PDF, which goes stale. Verified
What leaving costs
Exit fees, cooling off and complaints
Exit feeEDF will not tell you the amount without looking at your account.
Their own pages say only that a fee may apply if you leave 49 days or more before your tariff ends, that every tariff differs, and that it can depend on whether you are staying with EDF or moving away. The figure lives in your Tariff Information Label. A £25-per-fuel figure circulates widely; we could not find it anywhere on edfenergy.com, so we are not repeating it.
Cooling off14 days
Fourteen days. If EDF has not started supplying you, telling them is enough; if supply has begun you still have the window but pay for the energy used.
ComplaintsEight weeks
Email, freepost or the number above. Escalation to the Energy Ombudsman opens after eight weeks or on a deadlock letter, and EDF notes the Ombudsman’s own review can take up to twelve weeks.
The window worth knowing: Near the end of a fixed tariff you can leave free of charge even if your tariff carries an exit fee. 49 days is the common figure — British Gas, Octopus, E.ON Next and EDF all state it, and British Gas writes it as “49 days / seven weeks”, which is the same thing and explains why some suppliers quote weeks instead. Two do differ: OVO gives 53 days, and ScottishPower’s exit fee page says seven weeks in one section and six in another. Verified
