Thinking of Going Solar? Here’s Why Your Installer Must be MCS Certified



If you’re planning on installing solar panels, you may have heard the term ‘MCS certified’, but what does that mean? And more importantly – why should you care?

At SolarTherm UK, we believe in making solar simple, secure and stress-free. Choosing an MCS-certified installer is an important step in protecting your investment. Let’s break down what MCS certification is and why it’s absolutely essential when going solar in the UK.

What is MCS?

MCS stands for the Microgeneration Certification Scheme – a nationwide quality assurance scheme supported by the UK Government. It ensures that both your installer and the equipment they install meet the highest standards for safety, performance and quality.

Why should you only use an MCS-certified installer?

  • Access to financial incentives

To benefit from the Smart Export Guarantee (SEG) payments you’ll need an MCS certificate to prove your equipment meets safety requirements to export back to the grid.

Many government backed schemes, such as VAT relief and finance options require using an MCS-certified installer to qualify.

  • Proof of a proper installation

An MCS certificate is your guarantee that your solar PV system or battery storage has been installed by a qualified installer, safely and that your equipment meets UK technical standards. Your certificate also guarantees that your legally compliant with building regulations.

  • Better property value and resale confidence

If you want to sell your home in the future, the MCS certificate is needed. It shows potential buyers that the solar installation is legitimate, properly registered and that all relevant certificates and permissions have been received. The MCS certificate also allows potential buyers to know they can benefit from SEG payments if they purchase the house.

  • Manufacturer warranties and insurance support

Many warranty claims require MCS certification to be valid. Some insurance companies may also refuse cover or compensation if your system hasn’t been installed by a MCS-certified installer.

What happens if you don’t choose an MCS certified installer?

An uncertified installer may be cheaper, saving you money on your initial investment, but in the long run you’ll miss out financially. By using an uncertified installer you will miss out on SEG payments, won’t have as much legal protection and will be missing proof for resale and warranty claims. On top of that, with no regulation, you can’t be sure that the system installed is safe or at UK quality standards.
