Why our Accreditations Matter

Accreditations That Guarantee Confidence

Certified Renewables isn’t just “certified enough.” With full NICEIC, MCS accreditation, RECC membership, and IWA-backed warranties. That means every CRS client receives a fully compliant, safe, high-performance renewable energy system—and the confidence that comes with it.

When you choose Certified Renewables, you’re not guessing—you’re choosing a company that’s fully certified, rigorously vetted, and client-trusted. Our accreditations mean one thing: we deliver top‑tier renewable energy installations with complete integrity.
