Frequently asked questions
What does Good Energy’s B Corp certification mean?
B Corp certification means Good Energy has been independently verified against standards for social and environmental performance, transparency, and accountability — it’s the only UK home energy supplier to hold it.
Is it free to switch energy supplier?
Yes — switching suppliers in the UK is free, and by law your physical energy supply is never interrupted during a switch.
How long does switching take?
Typically around 3 weeks from agreeing to switch to your new supplier taking over, though some suppliers offer faster switches.
Will I lose supply while I switch?
No — the gas and electricity itself doesn’t change, only who bills you for it. No engineer visit or physical work is needed at your property.
Can I switch if I’m on a fixed-term contract?
Usually yes, penalty-free, if your current term ends within 49 days. Switching earlier may trigger an exit fee — worth checking your current contract first.
