How Mitchells & Butlers run GeoSphere across a 1,600-site estate

Energy waste across 1,600 sites that no one could see

Mitchells & Butlers run around 1,600 pubs, bars, restaurants and hotels across well-known brands including All Bar One, Harvester, Toby Carvery and O'Neill's. At that scale, energy is one of the largest controllable costs in the business, but waste was hard to see and harder still to act on.

Equipment was running when it did not need to, and faults often surfaced only after a breakdown, once a cellar had warmed up or a kitchen line had gone down. Without a clear view across every site, there was no reliable way to find the waste early or to prove where the savings were coming from.

Visibility and control, without the complexity

The partnership started in October 2021 at an Energy Forum. Mitchells & Butlers wanted real visibility and control over energy across the estate, but without adding complexity for the teams running each site. Just as important, they wanted a partner who would run the whole thing end to end, from survey through to ongoing management, rather than handing over a tool and walking away.

GeoSphere for Hospitality, led by GeoEnergy

• Energy monitoring and control across boilers, HVAC, cellar cooling, beer lines, coolers, fridges and outside lighting.
• A simple site dashboard with override, so duty managers keep control without complexity.
• A bureau team running monitoring, optimisation and maintenance support across the estate.
• Faults caught in the data feed and turned into a first-time fix through GeoWorks.

Savings evidenced, site by site

By January 2026 more than 1,000 installs were live, with the full rollout completing in 2026. The controlled scope is delivering around 5% saved on electricity and around 9% saved on gas, adding up to around £5m+ a year in combined energy and maintenance savings, with payback under two years.

1. 1,000+ installs live by January 2026, with the full estate rollout completing during 2026.
2. Around 5% electricity and 9% gas saved across the controlled scope.
3. Around £5m+ a year in combined energy and maintenance savings, with payback under two years.
4. A beer line cooler predictive-maintenance pilot paid back in around seven months.
5. Minimal disruption to trading while sites were brought online.

Full estate rollout, deeper predictive maintenance

The full estate rollout completes in 2026. From there, the focus moves to deepening predictive maintenance, catching more equipment issues in the data before they reach a breakdown, building on the beer line cooler pilot already proven across the estate.
