What MCS is
The UK's quality mark for solar and batteries.
MCS, the Microgeneration Certification Scheme, sets the standards for small-scale renewable energy in the UK. It certifies the products and the businesses that install them.
Certifies installers
MCS-certified installers are assessed against MCS's installation standards for each technology they fit.
Certifies products
Panels, inverters and batteries are tested and listed on MCS's product directory.
Issues your install certificate
Every MCS install gets an MCS certificate. You need it to claim Smart Export Guarantee payments for the electricity you export.
The redeveloped scheme
What the redeveloped scheme changes.
MCS is moving every certified installer onto its redeveloped scheme, in phases through 2026 and into 2027. Here's what changes for you as a customer.
A Customer Commitment
Certified installers give customers MCS's Customer Commitment at first contact, before any contract. It sets out the protections you're entitled to.
A direct agreement with MCS
Each certified business signs an Installer Agreement directly with MCS, so MCS holds every installer to its rules.
Assessed on real installs
Assessment is risk-based and focuses on the quality of the installations a business actually delivers.
Financial protection on every install
Installers must provide an MCS-approved financial protection product for each customer. Ours is a 6-year IAA insurance-backed guarantee.
