Compare British Gas Prices With Top UK Energy Suppliers
British Gas is the UK’s largest energy supplier and perhaps has the best brand recognition of any British energy supplier. They are one of the ‘Big Six’ that traditionally dominate the energy market.
About British Gas
British Gas originates from the Gas Light and Coke Company, the world's first public utility company.
British Gas has undergone many iterations since then and became the British Gas Corporation in 1973. Now known as British Gas in England and Wales, it operates under Scottish Gas in Scotland. The current CEO of British Gas is Chris O'Shea.
They provide energy services to both residential and commercial customers, including micro-businesses and large multi-site companies. Bespoke contracts are available for business customers.
British Gas Business is a subsidiary of the company Centrica and offers, alongside business electricity & gas supply, a range of services for homes and businesses. These include installing EV charging points, commercial air conditioning unit services and installation, as well as plumbing and drainage services.
British Gas took on the customers of other energy companies when they went into administration or ceased trading several times. Notable recent examples include Breeze Energy in December 2019 and Robin Hood Energy in September 2020.

British Gas Tariffs For Business
British Gas offers a range of business energy tariffs tailored to different needs and contract preferences. Here's a summary of what’s currently available:
Fixed-rate tariffs
Secure your unit rates for the entire contract term (usually 1 to 3 years), helping you budget with confidence and avoid market volatility.
Standard variable tariffs
Prices can rise or fall in line with wholesale market changes. These are typically applied when a contract ends and no new deal is selected.
Dual fuel tariffs
Combine both gas and electricity in one package, with a single bill and potential savings from bundled pricing.
Pre-payment tariffs
Pay for energy in advance using a top-up method. Useful for tight budget control, though rates can be higher, and supply may stop when credit runs out.
Electric vehicle (EV) tariffs
Designed for businesses using electric vehicles, offering reduced rates for overnight charging (smart meter required).
British Gas Reviews
British Gas holds a strong 4.5 ★ “Excellent” Trustpilot rating, based on around 285,000 residential reviews, showing high satisfaction among household customers.
However, when broader services, such as business energy, meter installations, and complaints handling, are considered, ratings on platforms like Reviews.io drop significantly (e.g. ~1.2 ★).
Business customers in particular report more frequent issues, so it’s worth reviewing both sets of feedback before making a decision.

In addition to gas and electricity supply, British Gas offers a wide range of additional services to businesses:
- Boiler and heating maintenance
- EV charger installation
- Air conditioning services
- Plumbing and drainage cover
- Meter installation
- Energy efficiency advice
These value-added services are designed to support businesses, improve energy efficiency, and future-proof internal operations.
