Resource management company, Veolia, is helping the Royal United Hospitals (RUH) Bath NHS Foundation Trust to decarbonise its Combe Park estate following the start of a major upgrade that will deliver a carbon reduction of approximately 25 per cent from 2030 onwards.
The project has received £21.6 million grant funding from the Public Sector Decarbonisation Scheme (PSDS), which is administered by Salix on behalf of the Government’s Department for Energy Security and Net Zero (DESNZ). The Carbon and Energy Fund (CEF) led on the development of their PSDS Salix application and procurement of the project.
The project for the district general hospital will deliver wide ranging energy and infrastructure improvements to save around 45,000 tonnes of carbon over the life of the contract. Delivered through Veolia’s strategic GreenUp plan, the upgrades have been designed using the holistic whole building approach that accounts for how facilities and the energy delivery systems interact with each other.
Planning applications for upgrades covering the desteaming of the majority of the heating distribution network and replacing aging infrastructure, along with the removal of the existing boiler plant and installation of a new low-carbon heating system, including 2.2MW of air and water source cascade heat pumps, was approved in February 2025. These installations have the capacity to significantly reduce carbon emissions and will be further supplemented with low-grade and high-grade heat from the existing combined heat and power plant, and continue the steam supply to the autoclaves used for sterilisation.
On site generation of renewable electricity will come from a new 300kWp solar array which will reduce the carbon impact of electricity, with potential future inclusion of battery energy storage. A new building management system will provide the essential control of all the systems and enable greater oversight and control of energy expenditure.
Other supporting works include building fabric improvements, new LED lighting, insulation, high voltage electrical infrastructure, and upgrading the on-site energy systems to extend the lifespan of existing equipment.
John Abraham, Chief Operating Officer – Veolia UK & Ireland – Industrial, Water & Energy said: “Our work with the Royal United Hospitals Bath over the past 13 years has provided us with a unique understanding of the site. By using this experience, and our wider carbon reducing energy projects across more than a hundred NHS sites, we will be able to deliver major carbon reductions that exceed the government’s targets, making it future proof for years to come.
“This key decarbonisation project for healthcare is another example of our strategic GreenUp plan in action as we help the NHS advance towards their net zero goal. We look forward to continuing our long standing partnership with RUH and helping them achieve their environmental targets.”
Toni Lynch, Chief Nursing Officer at the RUH said: “The RUH is committed to supporting the NHS’s ambition to become the world’s first Net Zero health service, for the benefit of our patients, staff, and wider community. This carbon-saving project marks a crucial milestone on that journey, and we’re proud to be working in partnership with the CEF, Salix and Veolia to make it a reality.”
Veolia has been working with the RUH since 2011, and currently provides energy and facilities management to over 100 hospitals in the UK. These support the healthcare for around 8.1 million inpatients each year, and reduce CO2 emissions in the healthcare sector by 120,000 tonnes.
