Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate his Department has made of the potential energy savings for the hospitality sector through the adoption of heat recovery systems.

The Department for Energy Security and Net Zero (DESNZ) does not hold an estimation of heat recovery potential specific to the hospitality sector, though in 2014 the Department of Energy and Climate Change published research on the potential for recovering and using surplus heat from industry.

DESNZ also incentivises Combined Heat and Power (CHP) across many sectors, an efficient process that captures and utilises the heat that is a by-product of the electricity generation process, via the voluntary Combined Heat and Power Quality Assurance (CHPQA) Programme.

Sites with CHP typically see savings of around 20% on their energy costs. In 2024, there were 206 CHP installations in buildings classified as hotels in the UK (Digest of UK Energy Statistics 2025), the closest approximation to hospitality in the data.
