Switch your business energy to Octopus and claim £100 credit — twice the household referral amount.
(Domestic customers get £50. Business customers get £100.)
Switch Business Energy to Octopus →Important: Business referrals work differently to household ones. You cannot use a standard referral link. Sign up via the Octopus business portal, then contact them with a referral code to claim your £100.
Octopus Energy has grown rapidly in the business energy market, and for good reason. They bring the same refreshingly transparent approach that has made them the UK's most popular domestic energy supplier to their business tariffs too. For small businesses, sole traders and larger organisations alike, Octopus delivers a compelling combination of competitive pricing, renewable energy and genuinely good customer service.
Energy costs are often one of the top three overheads for a business. Switching to a more competitive supplier — and claiming a £100 credit in the process — is one of the quickest wins a business owner can make.
Demonstrate your green credentials to clients and customers. Octopus supplies 100% renewable electricity as standard.
Fixed and variable options available. Octopus even offer a zero standing charge tariff for eligible businesses.
No surprise charges or confusing bills. Octopus provides simple, transparent invoicing that works with your accounting.
Business customers get access to the same award-winning customer service team that keeps Octopus top of Trustpilot year after year.
Before switching, review your existing contract for any exit fees or notice periods. If you have significant exit fees, it may be worth waiting until closer to the end of your contract — though the £100 credit and ongoing savings often outweigh this.

Complete the sign-up process online, selecting the tariff that suits your business — fixed rate for budgeting certainty, or variable for flexibility. Make sure you register as a business, not a household, to qualify for the £100 credit.
This is the key step. Unlike household customers who can simply click a referral link, business customers must contact Octopus Energy by phone or email after signing up to provide their referral code. Quote our code to receive your £100 credit.
Octopus will contact your existing supplier and manage the entire switching process. Your energy supply will not be interrupted. Once your switch is confirmed, your £100 credit will be applied to your new account.

Yes, Octopus offers a zero standing charge tariff for eligible businesses — particularly useful for low-usage sites or seasonal businesses that want to minimise fixed overhead costs.
Yes. Once you're with Octopus, you can refer other businesses using your own referral code. Every business that switches earns you £100 credit — there's no upper limit on referrals.
The £100 credit is a great start, but here's how to keep energy costs low over the long term:
Octopus provides online dashboards showing daily and hourly consumption. Use these to identify wasteful patterns — office equipment left on overnight, heating running during unoccupied periods, and so on.
Fixed tariffs give budget certainty — great for businesses that need to forecast costs. Variable or time-of-use tariffs can be cheaper if you can shift energy-heavy tasks to off-peak hours.
Being powered by 100% renewable electricity is worth publicising. Add it to tender documents, your website and marketing. Many procurement teams now score suppliers on ESG criteria.
Once you're with Octopus, share your business referral code with suppliers, clients and contacts. Every business that switches earns you another £100 — no limit on referrals.
