Octopus Energy Referral (UK): Get £50 Credit on Your First Bill

Get £50 Octopus credit

Want the bigger picture before you switch? Tariffs, exit fees, supplier comparisons and the referral rules are all in my Octopus Energy guides hub.

How the Octopus Energy Referral Works

When you join Octopus using the referral link above, they apply £50 energy credit to your account once your switch is complete and your first Direct Debit has been taken successfully. That timing matters. You won't see the credit immediately after sign-up. Instead, it typically takes around four weeks from when you join, sometimes a little longer if the switch takes time.

The credit then reduces what you owe on future bills automatically. It shows as a credit line in your Octopus account, and you can check it by logging in to your account dashboard. Both you and the referrer receive £50, so the total credit between the two accounts is £100.

Step by Step: How to Claim the £50 Credit

1. Click the referral link: share.octopus.energy/kind-koala-802
2. Get a quote directly on the Octopus site and complete your switch online. Do not go via a comparison site, as the referral may not apply if you do.
3. Set up your monthly Direct Debit during sign-up.
4. Once your switch is complete and the first Direct Debit is taken, the £50 credit is added automatically within a few weeks.

The entire sign-up process takes around five minutes. Thanks to Ofgem's faster switching rules, the switch itself typically completes within five working days. Your energy supply won't be interrupted at any point during the process.

Eligibility Rules That Catch People Out

Before you switch, it's worth checking these points. Each one can affect whether the Octopus Energy referral credit applies to your account.

• Sign up through the referral link, on the Octopus website. Octopus says the reward only applies when you join directly through its site using the link. Join through a comparison site or any other third party and it has to honour that route instead, so no referral credit.
• The credit lands after the first monthly Direct Debit. It does not appear at sign-up. Octopus says it typically takes around four weeks from joining, longer if your old supplier is slow.
• Moving house does not earn a second credit. If you have already had a referral credit as an Octopus customer, Octopus will not add another one when you move.
• Prepayment meters work differently. On a key or card meter, sign up with the link and then ask Octopus for the credit, which it pays as a refund or pre-loaded credit. On a smart pay-as-you-go meter, ask Octopus to add it to the meter.

If you're unsure whether your situation qualifies, Octopus's own referral FAQs cover the edge cases in detail.

Why Octopus Energy in 2026

Octopus calls itself Britain's most awarded energy supplier, and its own referral page shows an Excellent rating from more than 869,000 Trustpilot reviews. Service is the main reason people move, though the tariff range matters too.

From 1 October 2026 the price cap sits at £1,723 a year for typical dual-fuel use paid by Direct Debit, as confirmed by Ofgem. Octopus prices its Flexible tariff at or below the cap. Its fixed deals are a different story this autumn: on 17 September 2026 its public prices put the 12-month fix above the cap in every region, which I tested in my fix-or-not guide. Ofgem announces the January cap on 25 November 2026.

On top of that, the £50 Octopus Energy referral credit makes the case even stronger. For more on what the current cap means for your bills, see my October 2026 energy price cap guide. For a broader look at how Ofgem regulates energy suppliers, see my post on whether Octopus is regulated by Ofgem.

Switching Your Business Energy to Octopus?

If you run a small business, work as a sole trader, or manage energy for a limited company or charity, Octopus also offers business tariffs with 100% renewable electricity. The business referral credit is £75 rather than £50, and you sign up directly with no broker or middleman involved.

Business energy works differently from domestic in a few important ways: the Ofgem price cap does not apply, VAT is charged at 20% (though some small businesses qualify for 5%), and the Climate Change Levy is added to bills. I cover all of this in detail on my dedicated Octopus Energy business referral page.

Is It a Referral Code or a Referral Link?

Effectively, the same thing. Octopus uses a personalised share link format rather than a traditional promo code. The link above (kind-koala-802) functions as the referral. There is no separate code to enter at checkout. You simply follow the link, get a quote, and sign up. The referral is tracked automatically.

What If I Forgot to Use the Referral Link?

If you signed up directly with Octopus but forgot to use a referral link, it's worth contacting their support team and asking if the credit can be added retroactively. According to their own blog, this is sometimes possible as long as you signed up through the Octopus website directly (not via a comparison site). However, there's no guarantee. The safest approach is always to use the referral link at the point of sign-up.

You can also check whether you can leave Octopus anytime if your circumstances change after switching.

Switch to Octopus and get £50 credit

Energy prices, tariffs, and referral offers can change. Always verify current rates directly with Octopus Energy. CoolCuration earns a referral credit when you switch using my link, at no extra cost to you.

Why a referral sometimes fails to track

When the £50 does not turn up, the cause is almost always one of four things:

• The sign-up started somewhere other than the referral link, such as a comparison site.
• The switch has not finished yet, usually because the old supplier is still handing over.
• The first monthly Direct Debit has not been collected, or it failed.
• The link was added after the account was opened through a third party, which Octopus cannot honour.

You can check whether the credit has landed in the app under Bills, where it shows as a referral reward, or on the website under Payments and then View My Balance History. The full rules are on the Octopus referral FAQ.

Octopus Energy Referral: FAQs

How much credit do you get with an Octopus Energy referral?

Domestic customers receive £50 credit, while business and charity accounts receive £75. The credit is applied to your Octopus account after your first Direct Debit payment has been successfully taken, typically within four weeks of your switch completing.

Can I use an Octopus referral if I'm on a fixed deal with another supplier?

Yes, but check your current contract for exit fees first. If you're within 49 days of the end of your fixed term, your current supplier cannot charge you an exit fee. If you're on a variable or standard tariff, you can switch at any time with no penalty.

Does the Octopus referral work if I sign up by phone?

Possibly not. Octopus's own referral FAQ says your friend must sign up using the referral link directly on its website for the reward to apply. So the online route is the safe one, and if you would rather join by phone, check with Octopus first that the referral can be added.

Is Octopus Energy the cheapest supplier in 2026?

Octopus has historically priced below the Ofgem cap, but the cheapest option depends on your usage, location, and tariff type. It's always worth comparing rates for your specific circumstances. What sets Octopus apart is the combination of competitive pricing, 100% renewable electricity, and consistently strong customer service.

Does the referral credit change my tariff?

No. The £50 sits on your account balance and comes off future bills. Your unit rates and standing charges are whatever your chosen tariff charges, whether that is Flexible Octopus, a fix or a smart tariff.

Can I refer more than one person to Octopus?

Yes. Once you're an Octopus customer, you'll get your own referral link in your account dashboard. There's no cap on how many people you can refer, and you'll earn £50 credit for each successful domestic referral (or £75 for each business referral).

What happens to my Octopus referral credit if I leave?

Any credit on your account is yours. If you leave Octopus with a credit balance, they'll refund it to you.
