On 5 February 2026, the Department for Energy Security and Net Zero confirmed £74 million to upgrade energy systems across 82 NHS Trusts, eight military sites and one prison. The package funds efficient lighting, solar panels, heat pumps and building fabric works. Examples include more than £1.2 million for solar at Lincoln County Hospital, £590,000 for batteries at The Harbour mental health hospital in Blackpool, energy management upgrades at RAF Lossiemouth, Waddington and Marham, and new solar plus fabric fixes at HMP Channings Wood. Of the total, £9 million will be delivered with Great British Energy to install batteries and solar. (gov.uk)

DESNZ estimates the measures will cut bills by almost £30 million a year across more than 190 NHS sites, with military bases in England and Scotland expected to save hundreds of thousands annually. Ministers say savings will be redirected to frontline services, from patient care to day‑to‑day running costs. (gov.uk)

Why it matters: NHS England is the UK’s largest public energy user, supplying power and heat to more than 13,500 buildings. Trust energy bills have nearly doubled since 2019 to over £1.4 billion, while healthcare contributes an estimated 4–5% of national emissions. Estates emissions have fallen 10% since 2019/20, but gas for heating still accounts for around 40% of the NHS Carbon Footprint-making low‑carbon heat and efficiency essential. (england.nhs.uk)

The technologies are proven. The Carbon Trust reports that replacing halogen with LED units can reduce lighting electricity use by roughly 65–85%, cutting costs immediately. Government analysis finds modern heat pumps are typically more than three times as efficient as gas boilers and can reduce CO2 by up to 70% as the grid decarbonises. Pairing rooftop solar with batteries increases self‑consumption and trims peak demand, strengthening resilience during price spikes. (carbontrust.com)

Great British Energy’s role is accelerating delivery. In October 2025, the government confirmed an expanded GBE solar programme worth up to £255 million for hospitals, schools and military sites. Within the NHS, a £100 million GBE allocation across 78 trusts is expected to generate 50–65 GWh a year, save around £8.6 million annually and pay back in roughly 7–10 years, according to NHS England. Today’s £9 million top‑up focuses on batteries and solar to deepen those savings. (gov.uk)

For defence and justice estates, upgrades at RAF Lossiemouth, RAF Waddington and RAF Marham will improve energy management and reduce running costs, while HMP Channings Wood will add nearly £0.5 million of solar panels alongside electrical and plumbing works to cut heat loss. DESNZ expects military sites to save hundreds of thousands of pounds each year. (gov.uk)

Delivery capacity is in place. NHS England reports more than £1.4 billion of Public Sector Decarbonisation Scheme funding has already been secured since 2020, over £135 million has gone into efficiency measures, more than half of the secondary care estate now uses LED lighting, and solar generation has tripled since 2019. The NHS Net Zero Building Standard should streamline design and procurement for new projects. (england.nhs.uk)

For estates teams, the near‑term priorities are practical: plan grid connections early for heat pumps and PV, size batteries for demand flexibility, and commission robust metering so savings can be published quarterly. Transparent reporting shows staff, patients and local communities where the money is being saved-and where it is being reinvested.

This is steady modernisation, not a headline grab. Lower energy use cuts exposure to fossil gas prices, improves resilience and reduces emissions from one of the country’s most important public services. If delivery stays on schedule, communities will see cleaner power, quieter wards and more funding for care throughout 2026 and beyond. (gov.uk)
