British Gas vs Yu: Business Energy Comparison

This business energy comparison looks at tariffs, contract length, pricing structure, renewable credentials, customer service, smart tech and fees, so you can weigh up British Gas vs Yu Energy for your own energy contract.

British Gas vs Yu at a Glance

Which Supplier Offers Better Business Energy Tariffs?

Neither British Gas nor Yu Energy 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, online-only and flexible wholesale contracts built around scale, while Yu Energy builds its range around named account management and quote-based pricing rather than published, one-size-fits-all rates.

British Gas Tariffs

Fixed Price Energy Plan

Rates are locked in for the length of the agreement, typically one to three years, with a discount available for customers who pay by monthly Direct Debit.

Best for:

• Budget certainty over a fixed term

• SMEs that want a single, predictable quote

• Businesses that would rather not manage a market-linked price

British Gas Lite

A lower-cost, online-only fixed-price service for small businesses, with contracts running from one to four years, a free smart meter and dedicated web chat support in place of a phone line.

Best for:

• Digitally confident owners who want the cheapest fixed option

• Small offices and shops with straightforward usage

Renewable Business Energy

Available to businesses using more than 150,000 kWh of gas or electricity a year, with electricity upgradeable to a 100% Natural Renewable Electricity option backed by UK-sourced Renewable Energy Guarantees of Origin (REGOs).

Flex Advantage

A flexible energy supply contract for businesses using more than 1GWh a year, giving access to an online purchasing portal for managing commodity risk and buying energy in tranches as the wholesale market moves.

Commercial Landlord Energy

Fixed and flexible contract options tailored for commercial landlords managing void periods and tenant transitions.

Yu Tariffs

Fixed Energy Plans

Rates are locked in for one, two or three years, with pricing quoted individually rather than published as a standard rate card.

Best for:

• Budget certainty backed by a named account manager

• SMEs and sole traders wanting a bespoke quote

• Businesses that want the same point of contact throughout the contract

Freedom Tariff

A rolling contract that can be ended with 30 days' notice and carries no exit fee, aimed at businesses that don't want to commit to a long fixed term.

Flex Energy Plans

For larger businesses, energy can be bought in tranches at wholesale prices rather than at a single fixed rate, letting bigger users manage risk as the market moves.

Pure Green Add-On

An optional upgrade available on any fixed plan, giving 100% renewable electricity backed by REGO certificates and carbon-neutral gas offset through the Verified Carbon Standard (VCS) programme.

Multi-Utility Bundling

Gas, electricity and water can be combined under one contract through Yu Water, with single billing and one point of contact across all three utilities.

Tariff Comparison Table

Winner: British Gas, for businesses that want the broadest choice of tariff structures and established large-business flexible purchasing. Yu Energy is a better option for businesses that want a named account manager and the ability to bundle gas, electricity and water under one contract.

Contract Length Scorecard

British Gas vs Yu Pricing Structure

Business energy quotes typically include:

Unit Rate

Price charged for each kWh consumed. As an example, British Gas's published maximum microbusiness rates as of January 2026 were around 38p per kWh for electricity and around 12.5p per kWh for gas on a one-year fixed contract, excluding VAT and the Climate Change Levy, though most businesses negotiate below these ceiling prices. Yu Energy does not publish a standard rate card; quotes are calculated individually based on location, usage and credit profile, with current pricing kept on its website rather than fixed in advance.

Standing Charge

Daily fee covering infrastructure and administration. British Gas applies a standing charge across its core tariff range, with published one-year microbusiness examples of roughly £3 to £4 a day for electricity and around £17 to £18 a day for gas. Yu Energy's standing charge is set per quote and forms part of its tolerance-based billing structure, where usage outside agreed levels is charged transparently against the agreed rate.

Pass-Through Charges

May include:

• Network costs, as explained in our guide to pass-through and fully fixed energy contracts

• Balancing charges

• Government levies

Capacity Charges

Applicable to some larger business connections with both suppliers.

Before signing a business energy contract, compare:

1. What is the standing charge, and is there a No Standing Charge option?

2. What is the unit rate?

3. Is the tariff fixed, rolling or flexible?

4. Are there exit fees?

5. What happens at contract renewal?

6. Are renewable tariffs included as standard, or available as an add-on?

Verdict: British Gas or Yu for Business Energy?

The right supplier depends largely on your business priorities.

Choose British Gas if you want:

• The scale and supply security of the UK's largest business energy supplier

• Zero carbon electricity included as standard on fixed contracts

• Established large-business account management and flexible wholesale purchasing

• A wide choice of tariffs, from online-only Lite through to Flex Advantage

Choose Yu Energy if you want:

• A named account manager handling your business, whatever its size

• Gas, electricity and water bundled under one contract

• A renewable electricity upgrade available regardless of your usage level

• A rolling contract option with no exit fee and 30 days' notice

For most small businesses, day-to-day supply quality differs little between suppliers, because all providers use the same national infrastructure. However, when comparing scale, published pricing and large-business flexible procurement, British Gas often edges ahead for businesses that want simplicity and an established brand, while Yu Energy is an alternative choice for firms that value a named point of contact and the option to bundle multiple utilities together. Either way, it's worth using our business energy comparison tool to check current quotes against other suppliers before you commit.
