Case study: Maximum comfort, minimum cost

Helping Whitbread become more energy efficient


Whitbread is the UK’s largest operator of hotels, restaurants and coffee shops, including Premier Inn and Beefeater, owning an estate of more than 1,200 buildings with over 65,000 individual air conditioned rooms.

The company set itself a carbon target to hit by 2020 so chose to work with us, relying on our experience in delivering large-scale, multi-site energy management.

After reaching its carbon target three years early, Whitbread set out a new target to reduce emissions across its estate while maintaining comfort levels for their guests. They needed to find a solution which monitored energy consumption and provided energy efficient solutions at a range of individual sites with differing demands and challenges.


“E.ON’s integrated approach and range of solutions spanned our entire energy strategy – from big data to investment including ongoing control and support – providing an effective hardware and software partnership.”

Cian Hatton, Whitbread

Our integrated approach and range of solutions spanned Whitbread’s entire energy strategy. We monitored an initial 90 sites, each with a different array of operational requirements and installed equipment. Those sites were remotely connected to our 24/7 Energy Management Centre to monitor consumption and operations. Using this insight, individual sites could be improved with a tailored package of energy efficiency measures.

Through analysing the consumption of a wide range of different sites, we provided Whitbread with a new level of understanding of its estate. From these learnings, energy consumption reductions have ranged as high as 35%, with some sites saving much more than expected. Overall results to date are ahead of expectations - an average reduction of 12% - and on course to exceed the expected return on investment.
