What is a plumbing Certificate of Compliance?
You've found a buyer, and the transfer now waits on one piece of plumbing paper. It concerns the water installation.
Two documents share this name. The City's transfer form is the one your attorney submits. It is completed by a City-registered plumber, and the City's transfer page has the form and the steps. PIRB, the Plumbing Industry Registration Board, also issues its own Certificate of Compliance, signed by a PIRB Licensed Plumber. The City's page does not mention PIRB, so ask your attorney which one the transfer needs.
PIRB describes its CoC as the licensed plumber's self-certification. It comes in triplicate: one copy for the owner, one for the authorities or insurers where relevant, and one for the plumber's own file.
You'll hear both called a plumbing CoC, a water CoC or a compliance certificate, so always ask which document is meant. Your attorney can tell you when to start.

Who can issue a plumbing CoC?
The City says the transfer form can only be completed by a City-registered plumber. Your handyman can't, and neither can a plumber who isn't on the City's register.
Only a PIRB Licensed Plumber can issue a PIRB CoC, and a plumber can be registered with PIRB without being licensed. That matters if your transaction needs a PIRB CoC. Our guide on how to check a plumber is registered walks through the tools and the questions to ask.
A plumber who is happy to be checked is a good sign. One who gets vague when you ask for a registration number is not.
When do you need the certificate?
Before transfer. The City's page says the form must be submitted before any property in Cape Town can be transferred to a new owner. Your attorney knows the timing of your sale.
That rule is the City of Cape Town's. If your property falls under another municipality, such as Stellenbosch, ask your conveyancing attorney which water certificate that municipality asks for.
The City's page says the conveyancing attorney submits the completed form by email. So the certificate travels with the rest of the transfer paperwork. Tell your attorney early that you're getting the inspection done, and ask what form they need.
Don't leave it to the week of transfer. If the inspection turns something up, you'll want time to deal with it.

What happens at the inspection?
The City's page sets the order out. The seller downloads the City's own form, a registered plumber inspects, does any remedial work and signs it, and the attorney submits it. The form can only be completed by a City-registered plumber.
The page also says a City water inspector will check selected properties, and that the City takes up any non-compliance directly with the plumber.
Before the plumber comes, ask what the inspection covers, how long it takes and what it costs. An inspection fee shouldn't be a surprise on the day. If the plumber finds a problem, ask for a list of anything that stops them signing, with a price to fix each item. You can compare that against a second quote if you want one.
If you're also replacing a geyser or redoing a bathroom before the sale, ask the plumber at booking whether the certificate can be handled in the same visit. See geyser repair or replacement and bathroom plumbing for those jobs.
Who pays for the certificate?
Ask your conveyancing attorney how the cost of the inspection, the form and any repairs is dealt with in the sale agreement. We don't give a rule here, because the pages we read don't set one out.
Get the answer before the inspection, so there's no argument afterwards.
What does a plumbing CoC cost?
One published figure exists in the sources we have read. FlowLeads, in its national geyser replacement price breakdown (published 12 May 2026, checked 9 November 2026), lists a certificate of compliance line at R300 to R600. It is one source's figure, it is national, and it does not say whether that line covers the inspection or only the paperwork.
What you pay depends on the plumber, the size of the property, and any repairs found at the inspection. Ask for the inspection price and the certificate fee separately, and ask whether repairs would be extra.
What a plumber costs explains how plumbing prices are built and carries the dated sources. Request a quote and we call you back. The plumber assesses the job and quotes.
Questions people ask
Can I sell my house in Cape Town without a plumbing CoC?
No. The City says its transfer form must be submitted before any property in Cape Town can be transferred. Ask your attorney about timing.
Tell your conveyancing attorney early so the timing works.
Can any plumber issue a plumbing CoC?
No. The City's transfer form can only be completed by a City-registered plumber. Only PIRB Licensed Plumbers issue a PIRB CoC.
Check the plumber's registration before booking.
How long is a plumbing CoC valid?
The sources we checked give no validity period, so we won't state one. Ask your attorney and plumber how long the City accepts it.
Does a PIRB CoC replace the City's form?
The City's page doesn't mention PIRB, so we can't say. Ask your conveyancing attorney which document the transfer needs before you book.
The attorney is the one who submits the City's form.
Does the plumbing CoC cover my drains?
The City's transfer form concerns the water installation. Ask the plumber exactly what the inspection covers before you book, and ask for it in writing.
If the sale needs anything else checked, your attorney can tell you.
Who pays for the plumbing CoC, the seller or the buyer?
Ask your conveyancing attorney how the inspection, the form and any repairs are dealt with in the sale agreement before the inspection is done.
We don't invent a seller-or-buyer rule.
