We are licensed


The Plumbing Industry Registration Board is in the process of rolling out a system whereby a Licensed Plumbing Practitioner will self-certify their plumbing work by issuing a plumbing certificate of compliance to the relevant owner, municipality, local authority and/or insurance. Through the process, the licensed plumber shall take ownership of their plumbing work and be held accountable for the said works.

Plumbing Certificates of Compliance are issued by licensed plumbers like Supa Nova to certify that their plumbing work complies with all regulatory installation requirements.

Supa Nova is a Johannesburg-based company, owned and run by Irwin Hackner. With an invaluable three decades of personal experience in the industry, Irwin doesn’t only know about the running of operations but is constantly improving service delivery through using the latest technologies.
