The MCS (Microgeneration Certification Scheme) is similar to the Gas Safe Register, but for low-carbon energy technologies instead of gas. Heat pump installers or companies that appear on the MCS installer finder will be certified and qualified to the standard needed to install a heat pump.
You’ll have to use an MCS-certified installer if you want to access the UK government’s Boiler Upgrade Scheme grant or Home Energy Scotland’s grants and loans.
A good place to find MCS-certified heat pump installers is using the MCS installer finder. If you’re in Scotland you can also use the
Home Energy Scotland Renewables Installer Finder.
