Octopus Energy Refer a Friend Code – 2026

Getting a £50 Octopus Energy referral code

Key takeaways
You get a £50 account credit when you switch your home energy to Octopus using a referral link.
The person who refers you also gets a £50 credit.
You must sign up directly through the link; using a comparison site will invalidate the offer.
Business switches earn a £75 credit, and heat pump referrals earn £100.
The credit usually takes two to four weeks to appear after your first Direct Debit clears.

Octopus Energy runs one of the most popular refer-a-friend schemes in the UK energy market. While many suppliers stopped offering sign-up bonuses during the recent energy crisis, Octopus kept its scheme open. If you use a referral link from an existing customer to switch your gas or electricity, you get a £50 credit added to your new account. The person who shared the link with you also gets £50.

The scheme is open to mostly everyone switching a residential supply, including people on prepayment meters and those moving into a new home. Octopus Energy has grown to become the UK's largest energy supplier, serving over 8 million customers across the country. It is known for its customer service and its range of smart tariffs, which can help households cut their bills if they shift their energy use to cheaper times of the day.

Our verdict

Switching to Octopus using a referral link is an easy way to get £50 off your first few energy bills, provided you do not use a comparison site.

How to use an Octopus refer-a-friend link

Claiming the referral bonus is straightforward, but you need to follow the right steps to make sure the system tracks your switch. You cannot just type a code in at the end of the process. Instead, you need to use a specific web link provided by an existing customer.

Steps to claim your £50 credit
1
Click the referral link
The link will usually look something like 'share.octopus.energy' followed by a random adjective, noun, and number. Clicking this takes you to the Octopus website and tracks your visit.
2
Get a quote and sign up
Follow the on-screen steps to get a price for your energy and complete the sign-up process. The £50 offer should show on the screen as you do this.
3
Wait for the switch to complete
Octopus will handle the transfer from your old supplier. You do not need to contact your old provider to cancel.
4
Pay your first Direct Debit
The £50 credit is not applied instantly. It usually takes around two to four weeks to arrive, as Octopus waits until your switch is fully complete and your first Direct Debit payment has cleared.
Watch: Do not use a third-party switching site like GoCompare or MoneySuperMarket. If you click a referral link but then go to a comparison site to finish the switch, Octopus has to pay a commission to that site instead. This means your referral tracking is lost, and you will not get the £50 bonus.

If you signed up directly through the Octopus website and forgot to use a referral link, you can sometimes add it later. You need to log in to your online account within a few weeks of your switch starting. Look for a pink box or a link in your account settings that says 'Forgot to use a referral code?' and paste the code in there. This usually works better on a desktop computer than on the mobile app.

Who is eligible for the £50 bonus?

Most households can claim the referral credit, but there are a few rules about who qualifies. The main rule is that you must be a new customer switching a residential property to Octopus Energy.

New customers only
You cannot claim the £50 if you already get your energy from Octopus at your current address.
Prepayment meters
You can claim the credit if you use a 'Pay As You Go' meter. The £50 is added to your balance, which you can transfer to your key or card, or use to clear a debt.
Home movers
If you move into a new house that is already supplied by Octopus, you can set up your new account using a referral link to get the £50.
Former Bulb customers
If you were moved to Octopus when they took over Bulb, you are already classed as an existing customer and cannot use a referral code for your current home.

There is no specific staff discount for NHS workers or Blue Light Card holders. However, anyone can use a standard refer-a-friend link, which often provides better value than a standard percentage discount anyway.

Higher rewards for businesses and smart technology

The standard £50 offer applies to normal home energy switches. If you are signing up a business or installing low-carbon technology, Octopus offers higher reward amounts.

Home energy switch
£50 credit
For both you and the referrer
Business energy switch
£75 credit
For both the business and the referrer
Heat pump or solar
£100 reward
Discount for you, credit for them

For business and charity accounts, the reward is £75 for both parties. Referring a business works in the same way as referring a home: share your personal referral link, and the £75 credit is added when the business completes its switch.

Octopus also runs a separate referral scheme for smart home technology. If an existing customer has had a heat pump or solar panels installed by Octopus, they can refer friends for the same service. If you use their link to get a heat pump or solar system installed, you and the person who referred you each receive a digital £100 gift voucher after the installation is complete. This scheme has become very popular recently, driven by the government's Boiler Upgrade Scheme, which currently offers a £7,500 grant towards the cost of air and ground-source heat pumps.

Choosing the right Octopus tariff and current energy costs

When you use a referral link, you are not tied to one specific tariff. The £50 bonus applies whether you choose a standard variable tariff, a fixed deal, or one of Octopus's specialist smart tariffs. To give you an idea of current costs, the Ofgem price cap for the period from July to September 2026 is £1,663 a year for a typical dual-fuel household paying by Direct Debit.[1]

Octopus Energy

Your actual bills will depend on how much energy you use and where you live. Recent changes to the way bills are calculated have altered how we pay for energy. From April 2026, government measures removed around £150 a year of policy costs from the typical domestic energy bill. This was an overall bill saving rather than a saving solely on fixed charges. The costs for the Warm Home Discount were also moved from the standing charge to the unit rate. Looking ahead, the government is setting up a new Bill Discount Scheme for early 2027, which will offer discounts of up to £250 a year to households living near new clean electricity infrastructure.

When you sign up, you can choose from several tariffs. Octopus supplies 100% zero-carbon electricity as standard across all its deals.

Tariff nameHow it worksBest for
Flexible OctopusA standard variable tariff. Prices go up and down with the Ofgem price cap.People who want a standard deal with no exit fees.
Octopus FixedLocks your unit rates and standing charges in for 12 months.Households that want certainty over their energy rates.
Octopus TrackerPrices change every day based on the real wholesale cost of energy.People willing to take a small risk to beat the price cap.
Agile OctopusPrices change every half-hour. Rates drop when wind and solar generation is high.Households that can shift their heavy energy use to outside the 4pm-7pm peak.
Intelligent Octopus GoOffers a very cheap overnight rate for charging a car and powering the home.Electric vehicle drivers with a compatible car or charger.
Cosy OctopusOffers three cheaper periods every day to run a heating system.Homes heated by an air-source or ground-source heat pump.

Octoplus rewards and extra perks

One of the main reasons people switch to Octopus is to get access to its rewards programme, called Octoplus. It is free to join, but you must have electricity supplied by Octopus, a working smart meter sending half-hourly readings and an active Direct Debit to take part. Once you sign up, you earn points which you can turn into account credit or use for high-street perks.[1]

Current Octoplus benefits include:

  • Free electricity sessions where any power you use during a set window is credited back to your account.
  • Weekly treats, such as a free hot drink from partners like Greggs or Caffè Nero.
  • Two tickets for £8 at Vue cinemas, plus 15% off food and drinks.
  • Discounted entry to National Trust and National Trust for Scotland locations.

As well as this, Octopus runs a 'Wheel of Fortune' game. Eligible Octoplus members can spin the Wheel of Fortune to earn Octopoints. Every spin wins at least 8 points, with a chance to win up to 800,000 points (£1,000). While you will not win every time, it is a good incentive to keep your meter readings up to date if you do not have a smart meter sending them automatically.

If you drive an electric car, being an Octopus customer also gives you access to the Electroverse. This is a single card and app that works across dozens of different public charging networks. Instead of downloading a new app for every charging station you visit, you tap the Electroverse card. The cost of the charge is added straight to your home energy bill, and Octopus customers often get a discount of 5% to 8% on the standard public charging rate.

What happens when you switch?

Switching energy suppliers is much faster than it used to be. Thanks to Ofgem's Faster Switching rules, transferring your supply to Octopus now typically takes around three to five working days. The process is entirely administrative, meaning nobody needs to visit your home to change any equipment.

A common worry is that you might lose your gas or electricity supply during the switch. This does not happen. Your energy supply remains completely continuous because the physical pipes and cables outside your house do not change. The only thing that changes is which company bills you for the energy you use.

Before you switch, check if your current supplier will charge you an exit fee for leaving early. If you are on a fixed-term tariff, exit fees are typically around £30 to £60 per fuel. If the exit fees cost more than the £50 referral bonus, it might be better to wait until your current deal ends.

Octopus Energy manages the whole switch in the background. They will contact your old supplier to tell them you are leaving, so you do not need to make any awkward phone calls. Once the switch is complete, your old supplier will send you a final bill, and Octopus will start taking your new Direct Debit. If you ever decide to leave Octopus in the future, they generally do not charge exit fees on their standard tariffs, giving you the freedom to move if you find a better deal.

Final thoughts on the Octopus referral scheme

Using a refer-a-friend link is the best way to join Octopus Energy, as it gives you a free £50 credit that you will not get if you sign up through a comparison site.

If you have already decided to switch to Octopus Energy, finding a referral link is a straightforward way to lower your first bill. The supplier offers competitive smart tariffs, excellent customer service, and rewards for using energy outside of peak times.

The only time you should pause is if your current supplier will charge you expensive exit fees to leave your contract early. Always check your current terms before you click the link to switch.

Pros
£50 credit applied directly to your account
Access to innovative smart tariffs and Octoplus rewards
Fast switching process with no loss of supply
Cons
Cannot be used alongside comparison site cashback
You need a smart meter to get the most out of the rewards
Credit takes a few weeks to arrive

Frequently asked questions

Can I withdraw the referral credit to my bank account?

Yes. As long as your Octopus Energy account is in credit and you have enough money left to cover your next bill, you can request a refund to your bank account. You can do this through the Octopus app or website, and the money usually arrives within three to five working days.

Can I get cashback from a comparison site as well as the £50 credit?

No. You have to use the referral link directly to get the £50 credit. If you click a referral link but then go to a comparison website to complete the switch, the tracking is lost, and you will not receive the bonus.

Do I need a smart meter to get the £50 referral bonus?

No, you do not need a smart meter to claim the £50 sign-up credit. However, you will need a working smart meter if you want to join the Octoplus rewards scheme or use one of Octopus's smart tariffs like Agile or Tracker.

Do Octopus Energy ever offer a £100 refer-a-friend credit?

Octopus currently offers a £100 reward for heat pump and solar installations, and £75 for business energy switches. They have occasionally doubled the standard £50 home energy credit to £100 for short promotional periods in the past, but the standard residential offer remains £50.

Can I use an Octopus refer-a-friend code if I am moving in?

Yes. If you are moving into a new home that is already supplied by Octopus, you can set up your new account using a referral link and still claim the £50 credit. You do not need to be switching from another supplier to qualify.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
