We’re proud to share some exciting news: SEFE Energy has once again become the UK’s largest non‑domestic gas supplier by volume.
Hospitals and research trusts have spent the past decade modernising how they diagnose and treat patients, but the energy infrastructure behind that progress has advanced far less. The next stage of healthcare innovation will rely on applying the same data discipline to energy as is already used in clinical systems.
As we approach the end of 2025, I would like to take a moment to thank you for your trust, your collaboration, and the many open and constructive conversations we shared throughout the year.
