Why Businesses Choose Octopus Energy

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.

How to Claim Your £100 Business Credit — Step by Step

1

Check Your Current Contract

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.

2

Get a Business Quote

Visit the Octopus Energy business portal at octopus.energy/business to get a quote for your premises. You'll need to provide your address, usage estimates and whether you need gas and/or electricity.

3

Sign Up as a Business

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.

4

Contact Octopus with a Referral Code

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.

5

Octopus Handles the Rest

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.

Frequently Asked Questions

How much credit do businesses get?

Businesses get £100 credit when switching to Octopus Energy using a referral code — double the £50 offered to household customers.

Can businesses use a referral link?

No. The standard referral link only works for household customers. Business customers must sign up via the Octopus business portal at octopus.energy/business and then contact Octopus by phone or email with the referral code to have the £100 credit applied.

Is Octopus suitable for large businesses or multiple sites?

Yes. Octopus Energy serves businesses of all sizes, from sole traders to large organisations with multiple premises. They can handle complex contracts and multi-site supplies under a single account.

Does Octopus offer business energy with no standing charge?

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.

Can I refer other businesses and earn more credit?

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.

Tips to Make the Most of Octopus Energy for Your Business

The £100 credit is a great start, but here's how to keep energy costs low over the long term:

📈

Track Your Usage

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.

🔒

Pick the Right Tariff

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.

🌿

Promote Your Green Credentials

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.

🔁

Refer Other Businesses

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.

Common Mistakes to Avoid When Switching

  • Forgetting to provide the referral code — the most common mistake. Without it you won't receive the £100 credit. Confirm with Octopus that the code has been applied to your account before ending the call.
  • Ignoring exit fees on your current contract — check your contract carefully. Mid-contract exit fees could exceed the referral credit. Wait for the right renewal window where possible.
  • Signing up as domestic instead of business — domestic and business tariffs are separate. An accidental domestic sign-up means £50 instead of £100 and the wrong tariff structure.
  • Not reviewing your tariff regularly — set a calendar reminder 3 months before your contract end date. Business energy deals move quickly and a quick review can save hundreds per year.

🌍 Why Renewable Energy Matters for Your Business in 2026

  • Many large corporate clients now require suppliers to evidence sustainable energy sourcing in tender submissions
  • Banks and finance providers increasingly factor ESG credentials into lending decisions
  • Staff — especially younger recruits — actively prefer to work for companies with strong green values
  • Being powered by 100% renewable electricity is free marketing — add it to your website, proposals and email signatures
