Octopus vs British Gas: Business Energy Comparison

This business energy comparison looks at tariffs, contract flexibility, renewable options, customer service, smart tech, fees, and which type of business each supplier suits, so you can weigh up Octopus vs British Gas for your own energy contract.

Octopus vs British Gas at a Glance

Which Supplier Offers Better Business Energy Tariffs?

Neither Octopus nor British Gas 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. British Gas leans on conventional fixed and flexible contracts, while Octopus has built a wider set of time-of-use and export tariffs around its smart meter data.

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.

British Gas Tariffs

Fixed Price Energy Contracts

Rates remain constant throughout the agreement.

Best for:

• Budget certainty

• SMEs

• Businesses wanting protection from wholesale market rises

Flexible Energy Contracts

Businesses purchase energy in blocks as market conditions change.

Best for:

• High consumption businesses

• Multi-site organisations

• Manufacturers

Green Energy Contracts

Electricity supplied through Renewable Energy Guarantees of Origin (REGOs).

Multi-Site Agreements

Single contract solutions for organisations with multiple premises.

Tariff Comparison Table

Winner: Octopus, for businesses that can shift load and want to be paid for solar or battery export. British Gas remains the simpler option for a straightforward fixed or flexible contract without managing time-of-use pricing.
