Octopus Energy referral code
Get £50 bill credit when you switch to Octopus Energy using a refer-a-friend link.
Octopus Energy's refer-a-friend scheme (also known as recommend-a-friend) gives new customers £50 off their first energy bill, plus £50 for whoever shared the link. I switched to Octopus in September 2019. The £50 credit landed in my account about a month after my first direct debit, with no code to type or form to fill.

My rating for this deal
This rates the Octopus Energy referral itself: what you get, what you have to do to get it, and how long it takes to arrive. It isn’t a rating of Octopus Energy as a company.
Why this rating
The strongest scheme on the site: it attaches to a switch you were making anyway, and the credit arrives on a timetable Octopus actually keeps. The only thing keeping it off a perfect score is that bill credit can’t be withdrawn, so the value stays locked to an account you have to keep holding.

What is Octopus Energy?

Octopus Energy is a UK energy supplier serving 6.8 million UK households (April 2024) on electricity Octopus reports as 100% zero-carbon. They are Ofgem-regulated, Which? recommended for nine consecutive years, and operate under the energy price cap.
Octopus was founded in 2015, and that household count makes it the largest UK electricity supplier (opens in new tab) by market share. The award is a Which? Recommended Provider (opens in new tab) rather than a survey placing.
The practical consequence of Ofgem (opens in new tab) regulation is that the standard variable tariff cannot charge above the government-set maximum, whatever happens to wholesale prices.
How does the Octopus Energy referral scheme work?
The Octopus Energy referral scheme (sometimes called recommend-a-friend) gives both the new customer and the referrer £50 in bill credit. You receive the credit after your first direct debit payment. There is no limit on referrals. Business customers get £75 instead of £50. There is no £100 energy referral: that figure belongs to the separate Smart Tech scheme for heat pump and solar installs.

There is no limit on referrals. Business customers get £75 instead of £50. There is no £100 energy referral: that figure belongs to the separate Smart Tech scheme for heat pump and solar installs.
The switch itself takes 2 to 3 weeks with no interruption to supply, and the credit follows the first direct debit rather than the switch completing, so the two dates are usually a few weeks apart.
Business customers switching to Octopus Energy for Business get the higher reward on the same link, with no separate business referral to find.
On the £100 people search for: it is not the energy referral. Octopus's own referrals page (opens in new tab) words it as “You get £50 credit, your friend gets £50 credit”, and £75 each on a business switch. The £100 is real, but it belongs to a different scheme: the Smart Tech referral for heat pump and solar installs. Referral sites publishing “£100 business credit” or “up to £75” for an energy switch have merged the two.

Octopus Energy is best for UK households who want renewable energy, excellent customer service, and competitive prices. EV owners benefit from cheap overnight rates on Octopus Go, and solar panel owners can earn money exporting excess energy.
The renewable electricity comes without a premium attached, which is the part that is not obvious from the marketing. Solar export is paid through Octopus Outgoing, a separate tariff from whatever you import on. And anyone who has spent an afternoon on hold with a legacy supplier is buying the service rating here as much as the price.

Referral Plug's full testing methodology is at https://www.referralplug.co.uk/methodology (opens in new tab).Does Octopus Energy offer a discount code, voucher code, or promo code?
No, Octopus Energy doesn't run public discount, voucher, or promo codes. Two schemes stand in for them. The refer-a-friend link is the sign-up reward: £50 in bill credit (£75 on a business switch) for both you and the existing customer who refers you, unchanged since at least 2019. Octoplus is the ongoing one, a free loyalty scheme whose Octopoints convert at 800 points to £1 of bill credit, alongside Saving Sessions and free-electricity hours. Octoplus has a real entry bar, though: Octopus asks for electricity supplied by Octopus, an electricity smart meter sending half-hourly readings, and payment by direct debit. Gas-only accounts are out, which is where mine landed when I moved my electricity to EDF in July 2026. Last verified: 7 September 2026. Compare how this works across every brand I cover in my UK voucher codes guide.Is the Octopus Energy referral £100?
No. It is £50 for you and £50 for the person whose link you used, sometimes called a recommend-a-friend or refer-a-friend reward, or £75 each on a business switch. Octopus words it as “You get £50 credit, your friend gets £50 credit” on its own referrals page, and the domestic rate has not moved since at least 2019. The £100 belongs to a different Octopus scheme: the Smart Tech referral pays £100 each on a heat pump or solar install, and £25 each on an EV charger. Referral sites advertising “£100 business credit” or “up to £75” for an energy switch are quoting neither figure correctly.How do I use an Octopus Energy referral code?
Click the referral link on this page, which takes you to the Octopus Energy sign-up page with the referral automatically applied. The referral link itself acts as your referral code: there is no separate alphanumeric code to type. Enter your postcode, choose your tariff, and complete the switch.How long does the Octopus Energy switch take?
A typical energy switch to Octopus takes around 2 to 3 weeks. You do not need to do anything with your old supplier: Octopus handles the entire process. Your energy supply will not be interrupted during the switch.When will I receive my £50 Octopus referral credit?
The £50 credit is added to your Octopus account after your first direct debit payment is successfully taken. This usually happens within your first month of supply.Can I refer more than one person to Octopus Energy?
Yes. There is no limit on the number of people you can refer (or recommend a friend to) at Octopus. Each successful referral earns both you and the new customer £50 in account credit.Does Octopus Energy supply renewable energy?
Yes, though Octopus's own wording is 100% zero-carbon rather than 100% renewable: it publishes the mix as 86.4% renewables and 13.6% nuclear, bought through power purchase agreements with more than 700 UK generators. They also offer green gas options where biogas is injected into the grid to offset your gas usage.Is Octopus Energy regulated by Ofgem?
Yes. Octopus Energy is fully licensed and regulated by Ofgem, the UK energy regulator. Their standard variable tariff is subject to the energy price cap, protecting customers from overpaying.Are there exit fees with Octopus Energy?
Most Octopus variable tariffs have no exit fees, so you can leave at any time. Fixed-rate tariffs may carry an exit fee, which is clearly stated when you sign up. Always check the terms of your specific tariff.What is the difference between Octopus Go and Octopus Tracker?
Octopus Go offers a cheap overnight electricity rate (typically 4 hours) ideal for EV charging and battery storage. Octopus Tracker follows the wholesale energy price daily, so your rate changes each day based on market conditions. Both require a smart meter.Can I switch to Octopus Energy if I'm renting?
Yes. If you pay your energy bills directly (not through your landlord), you are free to switch supplier. You do not need your landlord's permission. The referral reward still applies.Does Octopus Energy have an affiliate programme, and is it the same as refer-a-friend?
No. They are different. The refer-a-friend scheme covered on this page is for individual Octopus customers earning £50 bill credit per personal referral. Octopus also runs a separate affiliate programme for publishers, content creators and comparison sites who want a commercial partnership; that pays on different terms and requires an application. You can find their affiliate programme by searching 'Octopus Energy affiliate programme' or contacting Octopus directly.Is the Octopus heat pump or EV charger referral the same as the energy referral?
No. Octopus runs a separate Smart Tech referral scheme for home installations (heat pumps, solar panels, and EV chargers) via tech.referrals.octopus.energy, paid as a gift card rather than bill credit. The reward depends on the product: £100 each for a heat pump or solar system, £25 each for an EV charger. If you are switching your home energy supply, use the energy referral on this page. For a heat pump or solar install, see our Octopus heat pump and solar referral guide; for an EV charger, see our Octopus EV charger installation guide.Do I need a smart meter to switch to Octopus Energy?
No. You can switch to Octopus Energy and claim the £50 referral reward without a smart meter. However, some of the best tariffs (including Octopus Go, Intelligent Octopus, and Octopus Tracker) require a compatible smart meter. Octopus will install one for free if you need it after switching.What is the difference between Octopus refer a friend and recommend a friend?
They are the same scheme. Whether you see it called 'refer a friend' or 'recommend a friend', the process and the £50 reward are identical. Octopus uses both terms interchangeably on their website and app.Can I join Octopus Energy without a referral code?
Yes, you can switch to Octopus Energy directly through their website without using a referral link. However, you will miss out on the £50 credit that both you and the referrer receive. There is no downside to using a referral link, so it is worth doing.Do I need to enter an Octopus Energy referral code manually?
No. Unlike some referral schemes, Octopus uses a referral link rather than a separate code you type in. Click the referral link on this page and the £50 reward is tracked automatically: there is no form field or code entry step.What does Martin Lewis say about Octopus Energy?
Martin Lewis and MoneySavingExpert have repeatedly highlighted Octopus Energy as a top-rated UK energy supplier. In the annual MSE Cheap Energy Club survey, Octopus consistently ranks first for customer satisfaction. Lewis has noted their competitive pricing, strong customer service, and innovative tariffs like Octopus Tracker and Agile Octopus as reasons they stand out from larger suppliers.Is there an Octopus Energy discount for students, NHS staff, or people on Universal Credit?
No. Octopus does not price by occupation or benefit status, so there is no student, NHS, key-worker, Universal Credit, disability or low-income tariff discount, and no first-order discount for new customers either. The standard variable tariff sits under Ofgem's price cap, which sets the same ceiling for every household. What is open to everyone: the £50 refer-a-friend credit on this page (£75 on a business switch), and Octoplus, if your electricity comes from Octopus on a smart meter. If you are struggling to pay, that is a conversation to have with Octopus directly rather than a code to search for.Can I get the £50 referral credit if I sign up through an energy comparison site?
No. If you switch to Octopus through a comparison site like Uswitch or Compare the Market, the referral credit does not apply. To receive the £50 reward, you need to switch directly using a referral link (such as the one on this page) rather than going through a third-party comparison service.Does Octopus Energy offer a tariff with no standing charge?
Octopus Energy does not currently offer a standard tariff with zero standing charges. All their tariffs include a daily standing charge set by Ofgem's price cap. However, tariffs like Agile Octopus and Octopus Tracker can result in very low or even negative unit rates at certain times, which can significantly reduce your overall bill.Does Octopus Energy offer a business referral code?
Yes. Octopus Energy for Business offers a £75 referral reward for business customers who switch using a referral link. The same referral link on this page works for both domestic and business sign-ups: Octopus detects your meter type and applies the correct reward (£50 domestic, £75 business). Sole traders, SMEs, and multi-site operations all qualify.What does the referrer get from an Octopus Energy referral?
For transparency: the referrer (the existing Octopus customer who shared this link) receives the same £50 in account credit that you do. Both parties get £50 once your first direct debit clears. Octopus pays both rewards out of its customer-acquisition budget, so the price you pay for energy is unaffected by whether you sign up through a referral link or directly.
