What Is MCS?
The Microgeneration Certification Scheme (MCS) is a UK quality assurance framework for low-carbon technologies including heat pumps, solar panels, and battery storage. MCS sets standards for both the products and the installers of these technologies.
Why MCS Certification Matters for Heat Pumps
- BUS Grant eligibility: You can only claim the £7,500 Boiler Upgrade Scheme grant if your heat pump is installed by an MCS-accredited installer using an MCS-certified heat pump model.
- Manufacturer warranty: Many heat pump manufacturers require MCS-certified installation to validate their product warranty.
- Quality assurance: MCS-accredited installers must meet rigorous technical competency standards and use approved equipment.
- Insurance and liability: Installation by a non-MCS installer may invalidate your home insurance claims related to the system.
How to Verify MCS Accreditation
Always verify that your installer is currently MCS-accredited before signing a contract. You can check the MCS installer database at mcsregistered.com by searching the installer’s name or MCS number. An MCS certificate number typically takes the format HHIC-XXXXXXXX.
What MCS-Certified Installation Includes
An MCS-accredited installer must:
- Conduct a heat loss survey
- Design the system to MCS standards
- Install using approved products
- Complete an MCS commissioning checklist
- Issue you a commissioning certificate
- Register your installation on the MCS database
