British Gas is relaunching its PeakSave for Business scheme, giving thousands of small and medium-sized enterprises (SMEs) the chance to slash their bills with six weeks of half-price electricity.
The energy provider confirmed the popular trial will return on Wednesday 17 September and run every Wednesday until 22 October. Participating businesses will receive 50 per cent off their electricity between 11am and 4pm each week.
The initiative is designed to encourage SMEs to shift more of their energy use to times when demand on the grid is lower or when renewable generation is higher. By moving consumption away from peak hours, businesses can cut costs while also supporting the UK’s efforts to decarbonise its energy supply.
The PeakSave scheme has already delivered significant savings. British Gas said SMEs had collectively saved £236,000 so far this year by taking part, up from £57,000 in 2024. Nearly 60,000 eligible businesses with smart meters have been invited to join the new six-week trial.
Matt Wood, Director of British Gas Business, said the response to previous events made the return of the scheme an easy decision.
“Our business customers are extremely important to us, which is why we’re proud to bring PeakSave for Business back this September following the huge success of our last event,” he said.
“The scheme helps businesses save money and make use of cleaner, greener energy, and is another step toward cutting energy costs across the UK.”
Previous participants welcomed the initiative for its simplicity and impact. One business described the scheme as “straightforward to register” and said they were “pleased to have made savings”, while another praised it as “easy to understand and equally easy to participate in. We would certainly enrol again.”
PeakSave for Business is part of British Gas’s broader effort to support the UK’s transition to net zero by rewarding flexibility in energy use. For SMEs grappling with rising costs, the initiative offers an immediate way to cut bills while also contributing to a greener grid.
British Gas said it hopes more businesses will see the trial as a chance to unlock savings and demonstrate how commercial energy users can help balance supply and demand.
More information on PeakSave for Business, including details on eligibility and how to apply for a smart meter installation, is available on the British Gas business blog.
