British Gas vs SSE: 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 British Gas against SSE.

British Gas vs SSE at a Glance

Which Supplier Offers Better Business Energy Tariffs?

Neither British Gas nor SSE 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 SSE splits its range between simple fixed SME products and more complex shaping and cash-out contracts for larger, high-volume users.

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.

SSE Tariffs

SSE Protect

SSE's fully fixed option, with both energy and non-energy costs fixed for the contract term, offered on terms of up to three years and including 100% renewable electricity as standard.

Best for:

• Budget certainty covering every cost line, not just the unit rate

• Businesses that want to remove non-commodity cost risk entirely

• SMEs wanting a single, predictable invoice

SSE Choice

Fixes the wholesale energy price while allowing some non-energy costs to vary, offered on terms of up to three years and including 100% renewable electricity as standard.

Best for:

• Businesses comfortable with some non-commodity cost variation

• SMEs wanting a lower headline fixed rate than a fully fixed plan

SSE Green Saver

A specialised 100% renewable tariff that provides the certification businesses need to claim Climate Change Levy exemptions on their tax returns.

SSE Shaping

Designed for organisations that want a fixed usage profile alongside access to live market prices, aimed at larger, high-volume users managing wholesale risk.

SSE Cash Out

Aimed at businesses that want real-time visibility of usage and the ability to optimise demand against half-hourly prices.

Tariff Comparison Table

Winner: British Gas, for businesses that want the broadest choice of tariff structures and an online-only cheapest option. SSE is the stronger option for businesses that want renewable electricity included as standard on every fixed contract, without needing to hit a usage threshold first.

British Gas vs SSE Pricing Structure

Business energy quotes typically include:

Unit Rate

Price charged for each kWh consumed. 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. SSE's standard SME fixed product has typically ranged from 18p to 25p per kWh, depending on location and volume, though SSE does not publish its fixed business rates for new customers online, and quotes are calculated individually.

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. SSE's standing charge is set per quote and varies by product, meter type and region, with published out-of-contract rates available on its website as a reference point.

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.

Which Supplier is Better for Which Business Types?

British Gas vs SSE: Side-by-Side Summary

Key Questions to Ask Before Deciding

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?

7. Can smart meters be installed, and how are they used?

8. How are out-of-contract rates handled?

Verdict: British Gas or SSE 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 SSE if you want:

• Renewable electricity from the supplier's own UK wind and hydro generation, included on every fixed contract

• A fully fixed plan that removes non-commodity cost risk entirely, via SSE Protect

• Real-time demand optimisation for high-volume usage, via SSE Cash Out

• A supplier focused exclusively on commercial and public-sector energy

For most small businesses, day-to-day supply quality differs little between suppliers, because all providers use the same national infrastructure. However, British Gas edges ahead on independent review scores and tariff choice for straightforward SME contracts, while SSE stands out for businesses that want renewable electricity built into every fixed contract and are prepared to weigh that against a notably weaker SME service reputation. Either way, it's worth using our business energy comparison tool to check current quotes against other suppliers before you sign.
