Gas COC
Gas certificate of compliance in Johannesburg & the West Rand
A gas certificate of compliance (gas COC) is issued by an SAQCC Gas-registered installer. It follows an inspection against SANS 10087-1 and a passed leak and pressure test. You need one when gas is installed or altered, and when you sell a property with gas. Gas Wizards inspect, test and certify across Johannesburg and the West Rand.

Gas COC requirements
To get a certificate, the installation has to meet SANS 10087-1 in full: cylinders sited outside on a firm base and clear of openings and drains, a regulator matched to the appliances, fixed copper pipe with isolation valves, approved hoses only at the appliance, flues and ventilation where needed, electrical clearances around the hob, and a passed leak and pressure test. The full rules are on gas installation regulations in South Africa.
When you need a gas COC
- Selling a property that has a gas installation — the transferring attorney will ask for it.
- A new installation or any alteration — a new appliance, moved cylinders, a changed pipe run.
- Insurance — insurers can refuse a claim for an uncertified gas installation.
- A rental or body corporate that asks for proof the installation is safe.
What we check
- Cylinders — sited outside, stable, away from drains, openings and ignition sources.
- Regulator and pipework — correct regulator, copper on the fixed runs, clipped, sleeved through walls, isolation valves.
- Appliances — correctly connected, approved hose at the appliance only, flues and ventilation where needed.
- Leak and pressure test — the installation must hold pressure.
- Certificate — issued when it all passes.
When it fails
You get a list of exactly what failed and a fixed quote to put it right. Common fails: cylinders too close to a window or drain, a flexible hose used for the whole run, no isolation valve, or an appliance fitted without ventilation. Once it's fixed, we re-test and issue the certificate.
Inspections and leak tests
Smell gas, or just want the installation checked? The inspection and leak test are the same work that comes before a certificate. Smelling gas right now: close the cylinder valve, don't switch anything electrical on or off, open doors and windows, and call us from outside.
Does a gas COC expire?
No — there's no fixed renewal date. A certificate covers the installation as it was when it was tested; any change to the installation needs a new one, and when you sell, the buyer's side will usually want a certificate issued for the transfer.
What it costs
The price depends on how many appliances are on the installation and whether anything needs fixing first. Call 083 498 1693 with the number of appliances and where the cylinders stand and we'll give you the price on the phone.

Questions about gas certificate of compliance
Who can issue a gas certificate of compliance?
Only an installer registered with SAQCC Gas for the type of installation. Ask for the registration details on the certificate.
How long does a gas COC take?
For a typical house with one or two appliances, the inspection and test are done in one visit; the certificate follows once everything passes.
Is a gas COC the same as an electrical COC?
No. They're separate certificates from separately registered people. A property sale can need both, plus others.
