Why This Matters
More and more UK homeowners are choosing solar power to cut bills, increase property value and reduce carbon emissions. The standards behind the panels on your roof matter just as much as the panels themselves. That’s where the Microgeneration Certification Scheme (MCS) comes in. Choosing MCS certified solar panels and working with an MCS accredited installer ensures high quality equipment, eligibility for certain incentives and long term peace of mind.
What is the MCS Certificate for Solar Panels?
MCS is the UK’s independent certification scheme for small scale renewable technology. For solar installations, it means both the installer and the products are meeting defined standards for safety and quality. While not a legal requirement, at SolarTherm UK we strongly recommend using a MCS certified installer to protect your investment.
Operating requirements and safety standards are revised periodically and continue to evolve year on year.
Why Choose MCS Certified Solar Panels?
When insisting on MCS certified solar panels, you are insisting on quality and safety and there are some key benefits:
- Quality assurance – MCS sets the standards for design, installation and workmanship. Certified products and installers are audited.
- Access to incentives – many incentives (such as the Smart Export Guarantee) require your system to be MCS compliant. Without certification you may miss out on additional income from export.
- Resale value – properties with certified systems fare better on the housing market. One study has found that properties with an MCS certified solar PV system can sell for up to 14% more.
- Future proofing – as regulations tighten, you’ll be in a better position.
- Confidence and reputation – an MCS badge indicates the installer adheres to consumer codes, holds insurance backed guarantees and operates professional standards at a high level.
Do I Need an MCS Certificate for My Solar Panels?
Legally no, but when it comes to getting the most out of your solar investment and MCS certificate is highly advisable. An installation that has an MCS certificate provides you with peace of mind that your system has been vigorously tested for quality and safety compliance. Export payments under the Smart Export Guarantee (SEG) often require certification, proving your system has been installed correctly. Without certification, you may struggle to sell your home later on or access warranties.
How Do You Get the MCS Certificate for Your Solar Installation?
- Use the MCS website to find an MCS certified installer.
- MCS certified installers use MCS certified products.
- Installation is completed in line with relevant MCS installation standards.
- After commissioning, the installer issues your MCS certificate (usually within 10 days of completion).
- Keep your certificate safe, you’ll need it for incentives, warranties and if you sell your property.
What if I Install Solar Panels Myself?
While self-installation may sound tempting, there are significant drawbacks to doing it yourself. Your system won’t be eligible for MCS certification, warranties usually require certified installation so your cover may be void and incentives like the SEG may be inaccessible. At SolarTherm UK we recommend using an MCS certified installer to deliver a safe, compliant and long lasting solar PV system, find out more about self-installation in our dedicated article here.
How to Choose the Right Installer and Product – A Quick Checklist
When you’re ready to install solar panels, keep an eye on the following:
- The installer is MCS accredited
- Panels and mounting kits are MCS certified products
- System design is appropriate for your roof, orientation and expected output
- Warranties are clear
- Documentation is provided including your MCS certificate, commissioning paperwork and any warranty details
- Avoid very low quotes from unknown ‘man with a van’ installers who are not certified
By choosing the right installer from the start, you can save yourself time, money and the risk of long term issues. Choosing MCS certified solar panels and working with an MCS accredited installer makes good sense. In 2025, as solar technology evolves and regulations become more stringent, the MCS mark offers a solid foundation of quality, compliance and future proofing.
