EDF Energy and Octopus Energy are two of the UK's most-searched business energy suppliers, but they approach the job differently. EDF leans on its position as the UK's largest generator of low-carbon electricity and builds its small business offer around long fixed-term contracts, while Octopus built its reputation on time-of-use pricing, half-hourly data and a jargon-light digital account.
This business energy comparison looks at tariffs, contract length, pricing structure, renewable credentials, customer service, smart tech and fees, so you can weigh EDF against Octopus for your business energy contract.

Which Supplier Offers Better Business Energy Tariffs?
Neither EDF nor Octopus publishes a single standard business rate, because pricing depends on:
Business location
Annual consumption
Industry type
Meter type
Contract length
Credit profile
Regional distribution charges
It's worth noting that the two suppliers structure their tariff ranges quite differently. EDF leans on conventional fixed and flexible contracts built around long-term budget certainty, while Octopus has built a wider set of time-of-use and export tariffs around its smart meter data.
EDF Tariffs
Fixed for Business
Rates are locked in for the length of the agreement, typically one to four years, with a discount available for customers who pay by monthly Direct Debit.
Best for:
Budget certainty over a longer term
SMEs that want a single, predictable quote
Businesses that would rather not manage a market-linked price
Fixed for Business Online
A lower-cost version of the fixed tariff for businesses happy to manage their account entirely online, without phone-based account support.
Best for:
Digitally confident owners who want the cheapest fixed option
Small offices and shops with straightforward usage
Freedom for Business
A flexible, variable-rate tariff with weekly price reviews and no exit fees, so businesses can leave without notice.
Best for:
Businesses that don't want to commit to a fixed term
Companies wanting the option to switch again without penalty
Fixed Renewable Tariff
Electricity matched by UK-sourced Renewable Energy Guarantees of Origin (REGOs), combined with a fixed price, aimed at businesses that want a straightforward way to evidence renewable sourcing.
Multi-Site Agreements
Single contract solutions for organisations managing several premises under one account.
Octopus Tariffs
Fixed Contracts
Rates are locked in for the length of the agreement, with no hidden fees added to the unit rate or standing charge.
Best for:
Budget certainty
Small offices, shops and sole traders
Businesses that want a simple, all-in quote
Shape Shifters: Trio and Agile
Half-hourly, time-of-use tariffs that reward businesses for shifting consumption away from the 4 pm to 7 pm peak. Agile follows wholesale prices directly, while Trio splits the day into three simpler bands.
Best for:
Businesses with EV charging, batteries or solar on-site
Manufacturers with flexible plant or shift patterns
Sites that can move refrigeration, HVAC or back-office loads outside peak hours
Summer Saver
A seasonal tariff aimed at businesses whose energy use varies significantly across the year, such as hospitality and tourism operators.
No Standing Charge Tariff
Available to qualifying meters. The daily standing charge is reduced to zero, with that fixed cost built into the unit rate instead, which can suit low-usage sites.
Multi-Site and Export Tariffs
Multi-site portfolios can be managed under one account for switching, renewals and billing. Businesses with solar or battery storage can also access Panel Power and Shape Shifters: Export, which pays for electricity sent back to the grid.

EDF vs Octopus Pricing Structure
Business energy quotes typically include:
Unit Rate
Price charged for each kWh consumed. As an example, one comparison site reported a typical SME on an EDF 2-year fixed contract paying around 27.9p per kWh for electricity and around 8.3p per kWh for gas as of May 2026, though your own quote will depend on location, usage and credit profile.

Key Questions to Ask Before Deciding
Before signing a business energy contract, ask yourself:
What is the standing charge, and is there a No Standing Charge option?
What is the unit rate?
Is the tariff fixed, flexible or time-of-use?
Are there exit fees?
What happens at contract renewal?
Are renewable or half-hourly matched tariffs available?
Can smart meters be installed, and how are they used?
How are out-of-contract rates handled?
Is a dedicated account manager provided?
Can multiple sites be managed under one agreement?
Verdict: EDF or Octopus for Business Energy?
The right supplier for your company depends largely on your business priorities.
Choose EDF if you want:
A long fixed-term contract for budget certainty
Large-scale, low-carbon electricity backed by nuclear generation
A flexible tariff with no exit fees
Established large-business account management
Choose Octopus if you want:
Transparent, all-in pricing with few hidden fees
Time-of-use tariffs that reward shifting consumption
Strong support for EV charging, solar or battery storage
A digital-first account with fast self-service tools
For most small businesses, day-to-day supply quality differs little between suppliers, because all providers use the same national infrastructure. However, when comparing contract flexibility, large-scale low-carbon generation and long-term fixed procurement, EDF often edges ahead for businesses that want simplicity and certainty, while Octopus remains the stronger choice for businesses willing to actively manage their energy use in exchange for time-of-use savings and export income. Either way, it's worth using our business energy comparison tool to check current quotes against other suppliers before you sign.
