Spring into savings - PeakSave for Business returns
12 February 2026
As the days get longer, and businesses gear up for spring, we’re bringing back PeakSave for Business – your chance to enjoy half-price electricity every Wednesday from 10am to 3pm for 6 weeks starting 4 March until 8 April.1
It’s a simple, effective way to refresh your energy strategy and unlock even more savings.
Why spring is the ideal time to save
Seasonal changes often mean shifts in energy use – from adjusting heating to powering up for new campaigns. PeakSave for Business gives you half-price electricity during event hours, helping you manage these changes affordably, so you can focus on growth without worrying about rising costs.
Savings snapshot
Our PeakSave for Business customers have already saved more than £640,000 – a huge milestone that’s helping businesses reinvest in what matters most. Join the movement this Spring and add your story to the growing success.
Here’s how it works
- Events run every Wednesday, 10am–3pm, from 4 March to 8 April
- Your business receives half‑price electricity for all electricity used during those hours
- Savings appear automatically as a PeakSave credit on your bill
- PeakSave credits are capped at £100 per meter, per event
The more you’re able to shift activity into the event window, the more you save - up to the £100 per meter, per event.
We are a small church in a very deprived area. We don’t use a lot of electricity, but the pounds we save using PeakSave events help us stay viable. Signing up was quick and easy and enrolling in every event is simple.
It was very simple and quick to enrol in PeakSave, we think we have saved around £35 using PeakSave as we are only open half a day on Wednesday. We think it is very generous and when it becomes time to renew our contract, we will definitely stay with British Gas due to offers like this.

PeakSave for Business rewards customers for shifting electricity use to times when there's typically more renewable electricity available in the UK's energy system due to lower demand from domestic, commercial and industrial premises. This in turn reduces the need for energy generated by fossil fuels.
