MCS Certified Solar Installers Scotland — Why It Matters

Everything you need to know about MCS certification and why it's essential

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 — potentially losing £200–600 per year for the entire 25-year lifespan of your system. You can verify any installer's MCS status at mcscertified.com. Scottish Energy Efficiency is fully MCS certified — call 0141 230 0198.

Why MCS Certification is Mandatory

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 £5,000-15,000 in lost export earnings.
