General Chips describe how well-sourced a number is, not how good the supplier is. How we verify explains what each means.
The thing that surprises people
There is no cancellation line
Not because suppliers hide it, but because it does not exist. UK energy switching is initiated by the gaining supplier: you sign up with the new one and they arrange everything with the old one. Your existing supplier can only object if you owe them money.
So the numbers above are for querying a tariff, asking what an exit fee would be, or making a complaint. They are not for leaving, and any guide presenting them as a “cancellation number” has misunderstood how the market works. Verified
Free to leave
The last 49 days of a fixed tariff
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. If you are inside that window, an exit fee on your tariff is irrelevant — and if a supplier tries to charge one, that is worth challenging. The window is not supplier generosity — it comes from Ofgem’s end-of-tariff rules. The full explainer is here. Verified
