share.octopus.energy/sepia-star-913 Octopus referral code: questions and answers
Is there an Octopus Energy promo code, discount code or voucher code?
Not as such. Octopus doesn't advertise general promo, discount or voucher codes for switching. Its sign-up reward is the friends-and-family referral scheme: switch through an existing customer's referral link, such as share.octopus.energy/sepia-star-913, and you get £50 account credit for a home (£75 for a business). The referrer gets the same.
Can I add the referral after signing up?
Possibly, but don't rely on it. Octopus's referrals blog says that if you forgot to use a referral link, you can get in touch with the referral code and, as long as you signed up directly through its website, it can add the referral to both accounts. Its terms, though, say referrals claimed retrospectively aren't eligible. The safest way is to open the referral link before you get a quote.
Is there a bigger Octopus referral reward for businesses?
Yes. When a business switches to Octopus through a referral link, the business and the referrer each get £75 energy credit, compared with £50 for a home. It's paid after the switch completes and the first Direct Debit is taken.
Is the Octopus Energy referral code free to use?
Yes. Using a referral code costs nothing and doesn't change your tariff prices. You get the same rates plus £50 credit.
What is the Octopus Energy referral code?
