Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, pursuant to the Answer of 29 April 2025 to Question 46103 on NHS: Energy, over what period he has estimated that these measures would pay for themselves.

The NHS National Energy Efficiency Fund (NEEF) is a programme of investment delivering vital upgrades, like LED lighting, building management systems (BMS), and solar energy, to drive down trusts’ energy bills.

The published data suggests that investment in BMS’ in hospitals can payback in as little as two years, and investment in LED lighting will pay for itself in four years. Using data gathered for the recent Great British Energy £100 million capital investment in solar photovoltaics, payback is expected in approximately 13 years.

In the most recent NEEF funding round, the Department invested £95 million across January to April 2025, benefitting 114 National Health Service trusts. It is estimated that this investment will pay for itself through revenue savings by approximately 2030, and will go on saving money into the 2040s and beyond.
