About British Gas Business Energy
British Gas, part of Centrica plc, is the oldest and one of the largest energy suppliers in the UK, serving businesses of every size from single-site SMEs to large multi-site organisations. It's one of the original "Big Six" suppliers, and it supplies electricity from renewable sources. Businesses can choose from several tariffs, and smaller companies can use British Gas Lite, a digital-only option.
If you're a smaller business that's comfortable managing everything online, it's worth knowing that British Gas Lite is a separate, digital-only supplier under the same parent company (Centrica), with its own tariffs and account system. See our British Gas Lite guide for details; it operates independently, so a British Gas Business contract and a British Gas Lite contract aren't interchangeable.

British Gas's Green Energy & Fuel Mix
British Gas doesn't publish a fixed price list for business electricity and gas. That's standard across the business energy market: your rate depends on your postcode, meter type, annual usage, credit position and contract length, and wholesale costs move daily, so a published table would be out of date within hours of going live.
What typically affects the price you're quoted:
• Your region and network distribution area
• Meter type — standard, half hourly, or smart
• Annual consumption (kWh)
• Contract length — up to 4 years fixed, or standard variable
• Your business's credit position
Because rates change daily, the only reliable way to see what British Gas would charge your business is to run a live comparison rather than rely on a generic guide price.
British Gas offers a range of fixed and variable tariffs for business customers, including dedicated green options.
Business Fixed
Lock in your unit rates for up to 4 years. Includes:
• Fixed unit rates for budget certainty
• Online account management via Energy360 DataView
• UK-based business support team
Renewable & Zero Carbon Energy for Business
British Gas offers two dedicated green products: Renewable Energy for Business, matched 100% to renewable generation, and Zero Carbon Energy for Business, backed by a mix of nuclear and renewable sources. Both are useful if your business needs to evidence its environmental credentials for procurement, reporting or client requirements.
Standard Variable
Prices move in line with the wider energy market. Includes:
• Freedom to switch at any time, with no exit fees
• Potential savings if wholesale costs fall
• Typically higher rates than a fixed-term tariff
British Gas is the longest-established name in UK energy, and its zero-carbon electricity mix is a genuine differentiator. Here's a balanced breakdown to help you decide.
Advantages
• Longest track record of any UK energy supplier, with a well-recognised brand
• 90% zero-carbon electricity as standard, with dedicated renewable and zero-carbon business products available
• Wide range of tariff lengths, up to 4 years fixed
• British Gas Lite available as a simpler, fully digital option for smaller businesses under the same parent company
Potential Downsides
• Customer satisfaction has historically scored below several competitors in independent surveys, though British Gas reports recent investment in customer service
• Like any fixed-term energy contract, you're locked in unless you're on a variable-rate deal
• British Gas isn't always the cheapest supplier on our panel; prices change daily, so it's worth comparing live rates rather than assuming a fixed position
According to Which? (September–October 2025), based on a survey of 3,179 British Gas customers, the supplier's overall customer satisfaction was rated two stars, below the industry average. That rating covers domestic products and doesn't specifically reflect business energy services.
British Gas has publicly stated it has invested in customer service, including more frontline advisers and extended call centre hours, and has been recognised by some independent trackers for improved satisfaction scores year on year. As with any supplier, it's worth weighing independent review data alongside your own experience of their business support team.
British Gas business contracts are fixed-term, and exit fees can apply if you leave before the end of your agreement. It's worth reviewing your deal ahead of your renewal window to avoid being rolled onto more expensive out-of-contract rates. Our team can flag your renewal date and help you compare alternatives before it arrives.
British Gas's electricity supply is 90% zero-carbon, made up of a mix of nuclear and renewable generation.
