Get £50 bill credit when you switch to Octopus Energy using a refer-a-friend link.
Octopus Energy's refer-a-friend scheme (also known as recommend-a-friend) gives new customers £50 off their first energy bill, plus £50 for whoever shared the link. I switched to Octopus in September 2019. The £50 credit landed in my account about a month after my first direct debit, with no code to type or form to fill.

Octopus Energy is a UK energy supplier serving 7.7 million UK households (Dec 2025) on 100% renewable electricity. They are Ofgem-regulated, Which? recommended for nine consecutive years, and operate under the energy price cap.
Octopus was founded in 2015, and that household count makes it the largest UK electricity supplier (opens in new tab) by market share. The award is a Which? Recommended Provider (opens in new tab) rather than a survey placing.
The practical consequence of Ofgem (opens in new tab) regulation is that the standard variable tariff cannot charge above the government-set maximum, whatever happens to wholesale prices.
The Octopus Energy referral scheme (sometimes called recommend-a-friend) gives both the new customer and the referrer £50 in bill credit. You receive the credit after your first direct debit payment. There is no limit on referrals. Business customers get £75 instead of £50.
The switch itself takes 2 to 3 weeks with no interruption to supply, and the credit follows the first direct debit rather than the switch completing, so the two dates are usually a few weeks apart.
Business customers switching to Octopus Energy for Business get the higher reward on the same link, with no separate business referral to find.
If you are switching to Octopus as a new customer, click a trusted referral link and the £50 tracks automatically: there is no code to type. If you are already an Octopus customer, your own referral link lives inside your account or app, and you share it directly. Both of you get £50 when a friend completes their switch.
Switching to Octopus as a new customer:
Already an Octopus customer? Your own link lives inside the Octopus Energy website or app under "Refer a friend". That URL is your Octopus referral code, which is why a search for a code to type turns up nothing.

Octopus Energy is best for UK households who want renewable energy, excellent customer service, and competitive prices. EV owners benefit from cheap overnight rates on Octopus Go, and solar panel owners can earn money exporting excess energy.
The renewable electricity comes without a premium attached, which is the part that is not obvious from the marketing. Solar export is paid through Octopus Outgoing, a separate tariff from whatever you import on. And anyone who has spent an afternoon on hold with a legacy supplier is buying the service rating here as much as the price.
Octopus Energy for Business offers a separate referral reward of £75 for business customers who switch using a referral link. The same link on this page works for both domestic and business sign-ups: Octopus detects your meter type and applies the correct reward.

| Fixed Octopus | Budget certainty | Locked rate for 12 months (when available) |
