If you’re researching solar panels or renewable energy systems, you may have come across the term MCS Certification. But what exactly does it mean and why is it important when choosing an installer?
MCS stands for Microgeneration Certification Scheme. This nationally recognised scheme sets clear standards for how renewable energy systems should be installed across the UK. When you choose an MCS certified installer like West Coast Electrical, you get peace of mind knowing your system meets a high standard and follows best industry practices.
Why Does MCS Certification Matter?
MCS certification ensures that both the installer and the products used (such as solar panels and inverters) meet rigorous quality and performance standards. It’s backed by the Department for Energy Security and Net Zero, and it applies to a range of low-carbon technologies including:
• Solar PV
• Battery storage (when installed as part of an MCS project)
• Heat pumps
• Wind and hydro microgeneration
Only MCS certified installations are eligible for certain government-backed financial incentives, such as the Smart Export Guarantee (SEG), which pays you for excess solar energy exported to the grid.
Without MCS, your installation won’t be recognised by energy suppliers for SEG registration. This may also affect the long-term value or compliance of your system.
What Does It Mean for You as a Customer?
When you use an MCS certified installer, you can expect:
• A system designed specifically for your home, based on your energy needs and roof size
•Certified manufacturers test and approve all equipment to ensure reliable performance
• Installation by trained professionals who follow strict safety and quality guidelines
• A handover pack and MCS certificate upon completion
The MCS certificate is your proof that the installation meets UK standards and it’s something your energy supplier or mortgage provider may ask for.

How Is MCS Different from Other Accreditations?
Many people find it confusing to navigate the number of schemes and accreditations in the renewables industry.
Here’s how MCS fits into the bigger picture:
• MCS: Certification for both products and installers — required for SEG payments and insurance-backed guarantees
• RECC: The Renewable Energy Consumer Code which covers consumer protection and contract standards
• TrustMark: Government-endorsed quality mark, this shows a company has passed independent assessment for quality and trading practices
All three work together to protect you as the customer, from the first quote to final handover.
How to Check If an Installer Is MCS Certified
You can search for MCS certified companies on the official MCS website:
Look for:
• The company name (e.g. West Coast Electrical)
• The technologies they’re certified to install (e.g. Solar PV)
• A valid certification number
If an installer can’t provide you with an MCS certificate after the job is complete, your system will not qualify for SEG payments and that’s something you should be aware of before signing any contract.
Why It Matters More Than Ever
As solar and battery systems become more popular, some companies may try to offer installations at low cost without proper certification. While the system may still work, it may not be eligible for export payments, could cause issues with your home insurance, or may not meet building regulations.
MCS certification gives you a level of protection that uncertified installations simply can’t offer. Certified installers complete the work to a high standard, using approved equipment and supplying documentation that holds long-term value.
