Updated 27 August 2026 By ForBusiness.net

Octopus Business Energy overview

Octopus Energy launched in 2016 and expanded through organic growth and acquisitions. Its business division says it now serves more than 100,000 businesses.

The supplier is known for technology-led account management and products linked to its Kraken platform.

Domestic tariffs, historic price movements and acquisitions explain the brand, but a business customer should focus on the exact commercial quote because domestic price caps and named tariffs do not necessarily apply.

Business tariffs and quotes

Octopus provides business electricity and gas quotations based on site and consumption details. Depending on the business and meter, options may include fixed contracts and products designed around renewable generation or smart consumption.

Compare unit rates, standing charges, term, payment method, taxes, pass-through costs, volume provisions and early-exit rules. Obtain separate written terms for each electricity and gas meter.

Renewable electricity and carbon claims

Octopus emphasises renewable electricity and investment in generation. When sustainability matters to procurement, ask whether the product uses renewable electricity backed by certificates, direct generation contracts or another mechanism.

Keep the supplier's electricity claim separate from the emissions created by gas consumption. A credible business claim should describe what was purchased, the period and the evidence rather than imply the entire organisation has no emissions.

Online account, meters and billing

The online account supports tasks such as bills, payments and meter readings, while smart meters can reduce estimates where connectivity and data are working. Verify which business meters and multi-site arrangements the portal supports.

Check invoice format, downloadable usage data, user access and the process for correcting an estimated or disputed reading. Multi-site businesses should ask whether accounts can be consolidated without hiding site-level consumption.

Customer service and contact routes

Octopus publishes business support routes on its official website and account communications. Use the business-specific channel for a commercial contract rather than a number copied from an undated third-party page.

For outages or gas emergencies, the network operator or national emergency service—not the supplier's ordinary billing team—may be the correct contact. Keep emergency details at the premises and train staff on the difference.

Octopus business energy pros and cons

Potential advantages include a modern online service, smart-energy capability, renewable positioning and direct business support. The supplier can suit a company comfortable managing its account digitally and interested in energy data.

Potential limitations are the same risks found across commercial energy: a quote can be difficult to compare, longer terms reduce flexibility, and service quality can vary by issue.

Businesses needing bespoke procurement or intensive multi-site support should confirm those capabilities before contracting.

Verdict and comparison checklist

Include Octopus in a business-energy comparison when its quote uses the same start date, consumption and contract assumptions as competitors. Read the written terms, not only a salesperson's summary.

Record the renewal window, commission position, meter data, complaint route and evidence for any environmental claim. Recheck all contact details through Octopus before relying on them.

Frequently asked questions

Does Octopus supply energy to businesses?

Yes. Octopus has a business-energy division for commercial electricity and gas.

Terms are based on the site, meter and quote.

Is Octopus business energy 100% renewable?

Check the precise product claim and evidence on the current quote. Renewable electricity claims and the emissions from gas or wider business activity should be described separately.

How do I contact Octopus Business Energy?

Use the business contact details on the official Octopus site or your bill. Do not rely on an old domestic number for a current commercial account.
