UK ETS: Hospital and Small Emitter status

Imported from official source

Installations that provide services to hospitals or meet the criteria to be classed as a small emitter can qualify for Hospital and Small Emitter (HSE) status under the UK ETS. HSEs do not need to surrender allowances to cover their emissions and are not entitled to receive any free allocation. They are instead set annual emissions targets for each scheme year.

To qualify for HSE status for the 2026 – 2030 allocation period, installations needed to apply within the baseline data collection window that was open from April - June 2025.

Lists of qualifying HSEs and their targets by allocation period

Installations which primarily provide services to a hospital

An installation could qualify if at least 85% of the heat its produces in a scheme year is used by or supplied to one or more hospitals.

Eligible installations also needed to meet the following conditions to qualify as an HSE for the 2026 – 2030 allocation period:

  • the installation primarily provided services to a hospital in the 2024 scheme year
  • have begun carrying out a regulated activity before 1 November 2025
  • be primarily providing services to a hospital after starting a regulated activity

    • Installations which do not primarily provide services to a hospital

    An installation qualifies as a small emitter if it:

  • emits less than 25,000 tonnes of carbon dioxide equivalent (CO2eq) for each scheme year in the relevant allocation period
  • has a total rated thermal input of less than 35 megawatts (MW) in the relevant period (if applicable)

    • Eligible installations also needed to meet the following conditions to qualify as an HSE for the 2026 – 2030 allocation period:

    If the installation carried out a regulated activity on or before 1 January 2021:

  • the installation’s reportable emissions were 25,000t CO2eq or below in 2021, 2022 and 2023
  • if installation was carrying out combustion activities, the installation’s rated thermal input was below 35MW in 2021, 2022 and 2023
