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.

Microgeneration Certification Scheme (MCS)

  • The UK’s gold-standard quality assurance for renewable tech (solar PV, battery storage, heat pumps).

  • Only MCS-certified installers can deliver installations eligible for government incentives like the RHI/Boiler Upgrade Scheme.

  • Every CRS engineer is MCS-certified—ensuring compliance, safety, and durability, plus seamless eligibility for subsidies and full warranties.

National Inspection Council for Electrical Installation and Contracting (NICEIC)

  • Rigorous Assessments: Thorough inspections of our work, premises, and staff against BS 7671 standards.

  • Ongoing Compliance: Regular reassessments to maintain high standards and Building Regulations

  • Client Protection: Insurance-backed warranties and a formal complaints process.

  • Committed to constant Professional Improvement

Renewable Energy Consumer Code (RECC)

  • RECC is the UK’s only Chartered Trading Standards-endorsed consumer protection scheme for the residential renewables sector

  • RECC Membership means we commit to transparent quoting, ethical selling, deposit guarantees, and robust after-sales support.

  • RECC ensures your protections include insurance-backed deposits, workmanship warranties, clear info before you sign—and independent dispute resolution if needed

Independent Warranty Association (IWA)

  • IWA is a leading UK-backed provider of insurance-backed guarantees and deposit protection since 1985

  • IWA approved installers are rigorously vetted on qualifications, workmanship, financial stability, and consumer satisfaction

  • We offer IWA-backed guarantees up to 10 years—covering materials, performance, and deposit protection.

TRUSTMARK

  • TrustMark is the UK government-endorsed quality scheme covering work a consumer chooses to have carried out in or around their home.

  • Being TrustMark-registered means we meet high standards in technical competence, customer service, and trading practices.

  • TrustMark gives you confidence that we are vetted and monitored regularly, and your project is protected through robust guarantees, clear communication, and access to an independent complaints process if required.

Chartered Trading Standards Institute Approval (CTSI):

  • Government-Recognised Quality Assurance - CTSI-approved codes represent the gold standard of consumer protection, giving you confidence that Certified Renewables operates to the highest ethical and professional standards recognised by UK Trading Standards.

  • Independent Dispute Resolution - Should any issues arise, our CTSI-approved code membership provides access to free, independent dispute resolution services, ensuring fair outcomes and professional mediation beyond standard consumer rights.

  • Continuous Professional Standards - Our commitment to the CTSI-approved code means we undergo regular compliance monitoring and professional development, ensuring we maintain cutting-edge expertise and ethical business practices that protect your interests.

ENERGY EFFICIENCY ASSOCIATION (EEA CIC)

  • The Energy Efficiency Association (EEA CIC) is a UK industry body representing organisations across the energy efficiency and retrofit sector.

  • Being associated with the EEA demonstrates our commitment to working in line with industry best practice, supporting collaboration across the sector, and staying engaged with the latest developments in energy efficiency and sustainable building standards.

  • The EEA provides a platform for knowledge sharing, training, and industry engagement, helping members stay informed and connected within the wider energy efficiency supply chain.
