British Gas Key Facts
Business Tariffs & Pricing
British Gas offers a range of fixed and variable energy tariffs. Choosing a tariff will depend on your desired flexibility and current wholesale prices. Locking in a fixed rate deal may be more favourable if wholesale prices are expected to increase. You’ll be able to choose a fixed rate for up to 4 years.
British Gas Lite (For SMEs)
For small businesses that are comfortable managing their energy online, British Gas Lite might be a better option with straightforward digital billing.
British Gas Business Prices per kWh
As of September 2025, a typical SME using 25,000 kWh of electricity per year could expect rates of around 27.2p per kWh with a daily standing charge of 62p. Your exact price will vary depending on location, contract length, and consumption profile – use our comparison tool for a personalised quote.
