Quick answer
Selling your home in Cape Town or Joburg? Here's when a plumbing COC is required, who can issue it, and what it costs.
This guide breaks down everything South African homeowners need to know about what is a plumbing compliance certificate (coc) and when do you need one? — based on current 2026 pricing, SANS regulations, and on-the-ground advice from PIRB-registered plumbers.
The legal basics
A plumbing Certificate of Compliance (COC) is required in Cape Town for every property sale, and in Johannesburg / Tshwane / eThekwini for any work involving the geyser, the water main, or fixed gas installations.
Who can issue one
Only PIRB-registered plumbers can legally issue a COC. The certificate covers a defined list of items — geyser installation, pressure-control valve, vacuum breakers, drainage, and water-meter accuracy.
What it typically costs
Expect R650–R1,500 for the inspection and certificate, plus the cost of any remedial work the plumber identifies.
