What is MCS?
MCS (Microgeneration Certification Scheme) is the the UK's national quality mark for small-scale renewable energy installations. It certifies both the products (solar panels, inverters) and the installers who fit them.
An MCS-certified installer has demonstrated they have the training, experience, and quality management systems to install solar panels safely and effectively. They are regularly audited to maintain their certification.
Why Choose an MCS-Certified Installer?
Quality Assurance
MCS installers must meet strict competency standards and follow industry best practices for installation.
Consumer Protection
Access to the MCS Consumer Code and warranty protection schemes if something goes wrong.
Government Scheme Eligibility
Required for the Smart Export Guarantee (SEG) payments and other government incentives.
Insurance Recognition
Many insurers require MCS certification for solar installations to be covered under home insurance.
Important: Non-MCS Installation Risks
Installing solar panels without MCS certification means:
- You cannot receive Smart Export Guarantee (SEG) payments
- You may not qualify for other government incentives
- Your home insurance may not cover the installation
- You have limited consumer protection if problems arise
- It may affect your property value when selling
