Quick Answer

MCS (Microgeneration Certification Scheme) certification is the UK industry quality standard that all Scottish solar installers must hold to register your system for the Smart Export Guarantee (SEG). Without an MCS-certified installer, you cannot earn money from your solar export — losing your export earnings for the 25-year system lifespan. You can verify any installer's MCS status at mcscertified.com. We install through MCS-certified partners. Call 0141 230 0198.

Why is MCS certification mandatory for solar installations in Scotland?

MCS certification is required to register your solar installation for the Smart Export Guarantee, which pays you for exported electricity. Without it, you lose your export earnings for the entire 25-year system lifespan.

SEG Eligibility

The Smart Export Guarantee (SEG) is the scheme that pays you for electricity you export to the grid. To register for SEG:

  • ✓Your installer MUST be MCS certified
  • ✓Your installation MUST be registered with MCS
  • ✓You need an MCS certificate for your system

Without MCS, you cannot register for SEG. Over 25 years, this could cost you all of your export earnings.

How do I verify an installer\'s MCS certification?

Visit mcscertified.com, search by company name or postcode, and check that the certification status is "Current." Note the certificate number and ask your installer to confirm it matches their documentation.
