Choosing a solar installer is about more than price. Our recognised certifications, technical assessments and consumer-code membership and Which? Trusted Trader endorsement provide independent reassurance before, during and after your installation. Our team invests in technical training, regular assessment and recognised industry certification so customers receive a safe, compliant and properly documented solar PV or battery installation. These registrations are not simply website badges. They represent ongoing responsibilities covering competence, installation standards, customer service and fair trading. Each organisation has a different role. Together they provide assurance covering technical work, renewable installation standards, customer care and trusted-trader assessment. NAPIT is a Government-approved, UKAS-accredited Certification Body operating within the building services and fabric sector. MCS is the UK quality mark for small-scale renewable energy technologies. Its standards cover how systems are designed and installed using certified products. TrustMark is the UK’s Government Endorsed Quality Scheme. Registered Businesses commit to required standards of technical competence, customer service and trading practices. HIES is a Chartered Trading Standards Institute-approved Consumer Code specialising in renewable and home-energy installations. Mr Solar has successfully passed the Which? Trusted Traders assessment and is recognised as an endorsed trader serving homes and businesses across Norfolk and Suffolk. Accreditation matters because customers need confidence that the system has been designed and installed correctly—and that appropriate support and consumer protections are available if something goes wrong. Confirm the business on the relevant NAPIT, MCS, TrustMark and Which? Trusted Traders registers rather than relying solely on a displayed logo. Look for a site-specific design, realistic generation estimate, clear equipment details, warranties and an itemised scope. Read the contract, deposit protection, workmanship warranty and complaints process before making payment. Speak to Mr Solar about a properly designed, accredited solar PV or battery installation.Qualifications that give you confidence.
