Your investment is protected by the highest regulatory standards in the UK. ASI Renewables is independently audited, fully certified, and government-endorsed for complete peace of mind.
Why Accreditations Matter
Consumer Protection
Working with an accredited installer ensures your deposit, warranties, and workmanship are completely backed by national insurance guarantee schemes, protecting your capital from start to finish.
Grants & Funding
You cannot access major government energy grants or smart export tariffs (SEG) unless your system is designed and signed off by an officially certified, registered company.
Quality Standards
Our team is independently audited and field-tested regularly. Every wire run, structural calculation, and safety switch we install complies strictly with UK building regulations.
Trustmark Approved
Trustmark is the UK Government-endorsed quality assurance scheme for tradespeople, working with the Department for Business and Trade. Registered businesses are independently vetted and regularly assessed against rigorous standards for technical competence, customer service and trading practices, giving homeowners confidence they’re working with a genuinely reliable and professional company.
MCS Certified
MCS (Microgeneration Certification Scheme) is the UK’s recognised quality standard for renewable and low-carbon technologies, including heat pumps and solar installations. Certification confirms our products and installation practices meet strict industry standards, and it’s required to access many government schemes and grants. Choosing an MCS-certified installer means your installation has been independently assessed and is regularly audited for quality and compliance.
Gas Safe Register
Gas Safe Register is the official, legally required register for gas engineers in the UK and Isle of Man, recognised by the Health and Safety Executive. Registration confirms our engineers have been rigorously assessed and are regularly checked, so you can be confident any gas work is carried out safely, legally and to the correct standard.

NAPIT is a government-approved certification body for UK tradespeople, covering electrical, heating, renewables and building compliance work. As a NAPIT-registered business, our work is independently assessed and regularly inspected against nationally recognised standards, allowing us to self-certify compliance with UK building regulations.
RECC Member
RECC (Renewable Energy Consumer Code) is a government-approved code of practice, backed by the Chartered Trading Standards Institute, that protects consumers buying renewable energy systems like heat pumps and solar. Membership means we’re held to strict standards for fair sales practices, honest advice and quality installation, with access to independent dispute resolution for extra peace of mind.
IAA Member
The Installation Assurance Authority (IAA) is a UK technical authority and certification body for insulation, heating and renewable energy installations. As a Competent Person Scheme, IAA membership means our work is independently assessed, regularly monitored and can be self-certified as compliant with UK building regulations, giving you confidence in the quality and safety of every installation.
