Get a £50 retail voucher when you switch energy supplier to E.ON Next
Switching energy supplier is one of the easiest ways to save money on your household bills, and using a referral code makes it even better. Both Octopus Energy and E.ON Next offer £50 in bill credit when you sign up through a referral link. The switch is handled entirely by your new supplier: you don't need to contact your old provider, and your energy supply is never interrupted. Most switches complete within 2-3 weeks.
Best UK energy deals in 2026
The best energy deal is the cheapest tariff for your actual usage, and that depends on your home and habits, so for raw price comparison a switching site like Uswitch is the place to start. What a referral adds is a flat £50 in bill credit (£75 for a business) on top of whatever Octopus Energy or E.ON Next tariff you pick. Neither supplier runs public discount codes, so the refer-a-friend reward is the only sign-up saving available.

For the suppliers we cover, the deal is the refer-a-friend reward: £50 in bill credit with Octopus Energy, or a £50 retail voucher with E.ON Next, paid on top of whatever tariff you choose. Neither runs public discount or voucher codes, so this is the only sign-up saving. For the cheapest unit rates, compare tariffs on a switching site first, then use a referral link to claim the credit.
