MCS-Certified Installations
What MCS certification is
MCS stands for the Microgeneration Certification Scheme. It rates installers and products against national standards for small renewable systems. Because MCS audits its installers, their design, fitting and paperwork follow a set process.
MCS is separate from the government. We are not part of MCS, so check any installer on the MCS website before you sign. That takes only a few minutes.
Why MCS matters for your money
MCS is the usual route to a regulated Smart Export Guarantee tariff. Ofgem allows other equivalent schemes, but suppliers often ask for an MCS certificate. Without proof, you may only qualify for a lower, non-regulated export rate.
Many grants and cheap loan schemes also ask for an MCS certificate. Because rules change, check the scheme guidance on GOV.UK before you commit. Our page on Feed-in Tariff and SEG advice explains how export payments work.
How to check an installer
- Ask for the company's MCS certificate number and search for it on the MCS website.
- Check that the certificate covers solar PV, and that it is current.
- Ask which consumer code the firm follows, such as RECC or HIES, and check that too.
- Request a written quote that names the panels, inverter, warranty terms and total cost.
- Ask who will do the work, because subcontractors need cover as well.
What MCS does not do
MCS is a quality scheme, not a promise that every job goes well. It does not set your price, and it cannot pick the best design for your roof. You still need to compare quotes and ask questions.
That is why we suggest a written quote from at least three firms. Our guide to comparing solar quotes shows what to put side by side.
How we use MCS
We only pass enquiries to installers that hold MCS certification for solar PV. You can check the number yourself before you agree to anything. We do not install panels, so the contract is always between you and the installer.
Coverage includes the areas in our guides to solar panels in Manchester and solar panels in Birmingham. If you already own panels, a certified firm can still help with battery storage systems.
MCS-Certified Installations: common questions
What is MCS certification?
MCS is the Microgeneration Certification Scheme. It certifies small renewable installers and products, and it is the usual route to a regulated export tariff.
Can I fit solar panels without an MCS installer?
You can, although you may miss out on a regulated Smart Export Guarantee tariff and some grant and loan schemes. Always check the rules before you order.
Does MCS protect me if something goes wrong?
Mostly no, because MCS is a quality scheme. Consumer protection comes from the code your installer follows, so ask which code applies and read what it covers.
