Quick answer

Sometimes Octopus may be able to help if you signed up directly through its website and simply forgot the referral code. The more reliable route is to use the personalised referral link before starting your quote.

When adding it later is less likely

Octopus terms restrict retrospective claims and referrals not made through a personalised link. If you used a third-party comparison site or another marketing offer, the referral reward may not apply.

Octo's rescue advice

Contact Octopus quickly and be specific. Say whether you signed up directly, give the referral code lotus-book-642, and explain that the referral link was missed before the quote was completed.

What to send Octopus

Best prevention

Open the referral link first, then complete the quote in that same journey. That avoids relying on a manual correction later.
