Octopus Energy’s Referral Scheme: A Renewable Discount or Just Another Promo?

Octopus Energy, one of the UK's more vocal proponents of renewable power, has been selling households on the promise of competitive rates and a gentler carbon footprint since 2016. It’s not the largest energy supplier in the country, but it has grown steadily - helped in no small part by an unusually aggressive referral system.

£50 for You, £50 for Them

The pitch is simple: refer a friend, and you both get £50 off your energy bills. Unlike other companies that outsource referrals to third-party systems like MentionMe - which can add an extra layer of friction - Octopus keeps it in-house. That means fewer hoops to jump through and, presumably, fewer excuses for delayed payouts.

Referral schemes like this aren’t unique to Octopus. They’re an easy way for companies to turn customers into unpaid marketers. But £50 is substantial, especially at a time when energy bills remain stubbornly high. "It’s a sensible mechanism for customer acquisition," says one industry analyst, who asked not to be named. "Cheaper than conventional advertising, and people trust a friend’s recommendation more than a banner ad."

The Fine Print (or Lack of It)

Octopus doesn’t bury the referral deal in endless terms and conditions. No minimum contract, no complex eligibility criteria - just a one-time £50 credit per referral. That said, there’s an obvious ceiling to how much any one person can benefit. It’s unlikely Octopus will let you power your entire home for free by convincing enough friends to switch.

What Octopus does gain, beyond a swelling customer base, is a soft edge in public perception. Green energy sounds nicer when it comes with a discount. That blend of ethical allure and financial incentive has worked well enough to keep Octopus expanding. Whether their rates will stay "pocket-friendly" in the long run is another matter.

A Good Deal… for Now

For existing Octopus customers, the referral scheme is one of the few straightforward ways to knock something off the bill. For prospective customers, it’s a £50 sweetener that may make switching marginally more appealing. And for Octopus itself, it’s a low-cost way to turn word of mouth into measurable growth.

Just don’t mistake it for charity.
