How to Verify a Plumber in South Africa (PIRB, CoC & Municipal Rules)

Johannesburg, Pretoria, Cape Town: the cheap WhatsApp is the same. A card photo is not a check. A logo on a bakkie is not a licence. Different jobs need different people and different paper.

This is the homeowner version. Name the job first. Ask for the numbers in writing. Look them up on PIRB — the search exists. Then don't mix three documents that all get called a "CoC."

This is not legal advice. Municipal by-laws differ. If a sale, insurer, or new connection hangs on a certificate, get a qualified read. WhatsApp is not a file.

Name the job first

Write the job type down before you search anyone.

• Burst tap / leak / unblock
• Geyser, solar geyser, or heat pump
• New drain or sanitary drainage
• New municipal water or sewer connection
• Property sale — especially Cape Town, where the City wants its own form

A tap washer and a transfer certificate are not the same trade conversation. A solar geyser and a drain to the municipal line are not either.

Ask for this in writing — before they quote

You want, on email or a PDF, not a voice note:

• Legal name of the person who will do or supervise the work
• Their PIRB registration number
• Whether they are PIRB Licensed or only Qualified (only Licensed may issue a PIRB CoC)
• Company name, and whether that company is listed with PIRB
• Which certificates are in the price: PIRB CoC, a municipal form, an electrical CoC — say which
• Who does the geyser electrics. Disconnecting terminals is electrician work, under a registered electrical contractor. "The plumber will just unhook it" is an incomplete quote

If they stall on the number, send a cousin's card photo, or say "the association will vouch," that's your answer.

Two different "registrations" (don't mix them up)

People say "registered plumber" like it's one stamp. It isn't.

Trained plumber (the competence rule). National Building Regulations A18: you don't practise the trade of plumbing unless you are a trained plumber — trade test / proficiency / construction plumbing NQF 3 — or you work under adequate control of one. That is about competence. It is not the same sentence as "must be PIRB."

PIRB. The Plumbing Industry Registration Board is the SAQA-recognised professional body for plumbers (ID 831). It registers individuals. It runs designations, CoCs, CPD, and a public verify search. SAQA lists it as non-statutory. It is not a government department, and it is not a statutory national licence in the way a DoEL electrical-contractor letter is.

PIRB designations that matter on a quote:

• Qualified — may do or supervise work under PIRB's scheme. Cannot buy or issue a PIRB CoC
• Licensed — extra PIRB assessment, plus 25 CPD points per cycle. May issue PIRB CoCs. PIRB Licensed plumbers agree to issue a CoC on work they undertake — that is a body rule, not a new Act

PIRB also lists Solar Installer and Plumbing Training Assessor. Ask which stamp you are looking at.

PIRB-listed company. Separate search. PIRB says a listed company should have at least one PIRB-registered plumber. The invoice name is not a substitute for the person on the roof.

IOPSA. The Institute of Plumbing South Africa is a voluntary industry association. Useful extra. Not the registrar. An IOPSA logo without a live PIRB Licensed listing is the plumbing version of treating an association card as the legal test.

Municipal register. Separate again. Cape Town keeps its own plumber register for City certificates. PIRB does not put you on that list automatically.

How to actually check (the search exists)

PIRB publishes a public lookup. Use it. Don't wait for a card in the driveway.

1. Look up the person

Verify a plumber — name or registration number.

Confirm:

• The name matches the quote
• Status is current
• Designation matches the job (Licensed if you need a PIRB CoC)

2. Look up the company if they quoted as one

PIRB listed companies

Then still check the individual. A listed company plus an unnamed "my guy" is not a Licensed plumber.

3. If they claim a PIRB CoC, treat "logged" as the test

After the work:

• Unique CoC number
• Your address — not a suburb-only line
• Licensed plumber's details

Then verify on Verify a CoC.

PIRB treats an allocated-but-unlogged CoC as unissued. Logging is supposed to happen within five working days of completion. "I'll log it after you pay the lot" is not a certificate. A homemade letterhead CoC has no real substance on PIRB's own telling.

The physical PIRB card is optional. A photo of a card is not verification. PIRB checks incoming trade certificates because a high number of them are misrepresented. Search the site.

4. Treat IOPSA as extra

IOPSA members and iopsa.org.za can be a useful second look. They are not a government licence and they are not the PIRB individual search.

Three documents that all get called a "CoC"

Do not mix these.

1. PIRB plumbing CoC
Self-certification by a PIRB Licensed plumber. Unique number. Must be logged. PIRB samples work for audit. Useful for a paper trail. It is not a Cape Town transfer form and not an electrical CoC.

2. Cape Town City water-installation / transfer form
A City form, signed by a plumber on the City register, submitted by the conveyancer to the City. Required before transfer of property in Cape Town. The City says it is checklist-limited — not a general quality document — and that the City is not liable for poor workmanship of registered plumbers. A PIRB CoC does not replace it.

Official how-to: Submit a certificate of compliance of water installation.
City register: Find a qualified registered plumber in Cape Town.

3. Electrical CoC
OHS Electrical Installation Regulations. Issued by a registered person for electrical work. If the geyser is disconnected, relocated, or the thermostat / PV-DC side is touched, you want an electrician and an electrical CoC. See how to verify an electrician.

There is no national "plumbing CoC to sell a house" the way the electrical CoC works on transfer. Johannesburg and Pretoria: ask the conveyancer and the municipality. Do not copy Cape Town onto Gauteng.

When the law, the municipality, the insurer, and PIRB each bite

Installations still have to be done properly. Compulsory national water standards still point at SANS 10252 / 10254 (or whatever replaced the old SABS numbers) for how consumer installations are built. That is not the same as "every job must have a PIRB CoC."

Electric storage geysers (SANS 10254). The CoC requirement in that standard was removed on 24 June 2022. The installation rules in the standard remain. Do not write "PIRB CoC is nationally compulsory for every electric geyser after that date." It isn't.

PIRB Licensed rule. Licensed plumbers still issue and log PIRB CoCs when the total value exceeds R1,500 (materials, labour and VAT), or regardless of cost for electric, solar, and heat-pump water heaters and sanitary drains. That is how they keep the designation. Body rule, not a new statute.

Solar geysers (SANS 10106) and heat pumps (SANS 1352). Industry still says a CoC sits in those standards until they are updated. Confirm the current edition, your insurer, and your municipality.

Drainage (NBR Part P). Drains must be inspectable and testable. They are not put into use until the local authority has inspected, tested and passed them. Don't backfill if building control still has to see the trench. That pass is municipal, not a PIRB card.

New water or sewer connections. Apply to the municipality. Not a WhatsApp "I'll hook it on."

Insurers. Cape Town's plumber page warns that most insurers won't cover work by a non-accredited plumber. Read your policy. A logged PIRB CoC is an audit trail — not a paid claim, and not a Completo promise.

PER 2025. Industry said in April 2025 the amendment process was complete and promulgation was still ahead. Not treated as in force here. Do not say plumbers are now licensed under PER.

The geyser trap

Plumbing the cylinder is one job. The electrical terminals are another.

IOPSA and the Electrical Contractors Association have said it plainly: only a competent electrician, under a registered electrical contractor, disconnects and reconnects geyser electrics. Relocating a unit needs testing and a new or supplementary electrical CoC. PV / DC controls are electrical work.

A plumber-only geyser quote that is silent on the electrician is incomplete. Hold the last payment until the paper that applies is in your hand — logged PIRB CoC if they issued one, City form if Cape Town wants it, electrical CoC if wires moved.

Red flags — stop the EFT

Walk away, or at least stop the payment, if you get:

• No PIRB number, or "I'll send the card next week"
• Qualified sold as Licensed "so I can do the CoC"
• Name on the quote ≠ PIRB listing ≠ person on site
• Company listing used to cover an unregistered person on the roof
• "PIRB extra" / "municipality never checks"
• Homemade CoC, or a number that does not verify as logged
• "I'll log it later" after you've paid everything
• IOPSA or Facebook "registered" with no live PIRB individual
• Cape Town sale: not on the City register
• Plumber offering to do the geyser electrical connection
• One-line quote: "plumbing R45,000" — no address, no certificate line
• Drainage: trench closed before municipal inspection
• 50%+ into a personal account with no supplier invoice for the unit
• Cash only, no invoice
• Won't do staged release

How Completo fits (verification + the money — not the workmanship)

Every contractor on Completo is verified before they can quote. For plumbing, that includes trade credentials where they apply. You should still run the PIRB search — and the City register on a Cape Town sale. Completo is not a substitute for those lookups. We do not claim a live PIRB feed, and we do not re-check anyone weekly.

Then the money. You don't dump a deposit into a personal account and hope. You pay into SafePay. Funds sit in a TradeSafe trust account, Standard Bank as custodian. Completo never holds or touches the money. Completo's 3.5% platform fee is built into the price you see — not a surprise at checkout, and not a Completo Guarantee product.

Hold the last release until the paper is verified: logged PIRB CoC if they issued one, City form if Cape Town transfer needs it, electrical CoC if electrics moved.

The contractor still owns the workmanship. Completo does not guarantee the work is up to standard. We can help both sides talk it through. We don't certify the job.

Verification without payment protection is a CV. Payment protection without a name you can look up is a locked box around the wrong person. Completo is built so both sit together — and you still check PIRB. You stay in control.
