Is there an Octopus Energy promo code, discount code or voucher code?

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.
