## In short

A government grant in England and Wales toward air source and ground source heat pump installation through accredited installers — grant levels and availability change; check gov.uk before booking. Scotland and Wales have separate schemes.

Installers apply for the grant on your behalf after MCS-certified installation.

Insulation and emitter sizing still affect running economics.

See heat pumps UK guide.
