Independent review of air source heat pump noise emissions, permitted development guidance and regulations published

The Department for Energy Security and Net Zero commissioned an independent review in 2023 of the current evidence on noise emissions from air source heat pumps (ASHPs).

This study assesses whether, and in what ways, current guidance and planning regulations are fit for purpose for the larger-scale deployment of ASHPs.

The research project used a mixed methodology, including a literature review, household research, and qualitative research with key stakeholders, including local planning authorities, ASHP manufacturers, ASHP installers, and industry bodies.

The research found that:

  • ASHP noise emissions were a concern for a minority of consumers in the study
  • the research found low incidence of ASHP noise complaints. These arose due to poor quality installations, including location and proximity factors
  • possible revisions to permitted development guidance and regulations

This information will help inform future government policy on heat pump planning guidance and heat pump standards.
