Frequently asked questions

How do OVO’s green rewards work?

OVO ties rewards and incentives to lower-carbon usage habits as part of its broader carbon-reduction commitments — specifics vary by current tariff, so check the details of the plan you’re offered.

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.
