How to use the referral link
If you are comparing tariffs, do that first. Return through the referral link if Octopus suits your home. For online signup, the link carries the referral details to Octopus; you do not need a separate promo code or voucher box.
Open the referral link
The button above takes you to Octopus's signup page. Use the link for the signup you actually complete. If you leave before finishing, return through the valid link when you are ready.
Complete signup directly online
Enter your postcode, choose a suitable tariff and complete your details on Octopus's website. Keep the confirmation email so you can check your tariff, Direct Debit and supply dates.
Check your account credit
Octopus adds the reward once it actively supplies your account and your first Direct Debit payment succeeds. Check your account balance or statement for the credit.
Who qualifies for the £50 credit?
The standard reward is for eligible domestic energy customers. The eligibility criteria in Octopus's affiliate terms require you to complete signup directly online through a valid affiliate link and reach active supply with a successful first Direct Debit.
Which routes and circumstances are excluded?
- Signing up by phone, through a price comparison site or through a third-party broker.
- Trying to claim retrospectively after completing signup without the link.
- Using a deactivated link or cancelling before supply starts or before your first successful Direct Debit.
- Having been an Octopus customer, including a white-label or sub-brand customer, in the last 12 months, except for the existing-customer provision below.
Can existing Octopus customers qualify?
An existing customer who has never received reward credit or a switching offer may be eligible by quoting a valid affiliate link. Customers who have already received a switching reward, including a refer-a-friend or affiliate offer, are not eligible. Ask Octopus to confirm whether the existing-customer provision applies to your account. A tariff change alone does not establish eligibility.
If you qualify for more than one marketing incentive, Octopus reserves the right to give you just one. Do not assume offers can be combined.
Common questions about the credit
When does the £50 credit arrive?
Octopus must actively supply your account and your first Direct Debit must have succeeded before the reward is added. The reward terms do not give a fixed number of days or weeks from signup. If both conditions are met and the credit is missing, contact Octopus with your signup confirmation and ask it to check the reward.
Is this a discount code or energy account credit?
It is £50 credit towards energy charges on your Octopus account. It does not reduce your tariff's unit rates or standing charges. The reward has no cash alternative and cannot be transferred, as set out in the reward terms.
What if I have already completed signup?
If you completed signup through a valid affiliate link, check your supply and first payment status before chasing the credit. If you completed signup without the link, opening it now does not attach it to that completed signup: the affiliate terms exclude retrospective claims. The separate existing-customer provision above may apply if you have never received a reward or switching offer, but Octopus must confirm your eligibility. It is not a guaranteed way to add missed credit.
Before you decide
Check the tariff, meter requirements and any exit fee with your current supplier before switching. The tariff guides can help you compare options. For a fuller explanation of the switch and what happens afterwards, read how the referral programme works.
