Gas Installations Cape Town covers the work itself: designing where the gas goes, running the line, positioning the cylinder, connecting the appliance, testing it and certifying it. Whether that is one hob or a whole-house system, the sequence is the same and so are the things that go wrong when a step is skipped.
New installations, alterations to existing ones, extensions to add an appliance, and removals of old gas that a buyer's inspector has flagged.
Describe what you want installed and where. Photographs of the kitchen or the cylinder position help a lot.
Request a Gas Installation QuoteWhat a Gas Installation Involves
- Site assessment. Where the cylinder can legally and practically stand, where the appliance goes, and what route the pipe can take between the two.
- Sizing. Cylinder capacity and pipe diameter against the total gas demand of everything that will be connected, now and later.
- Pipework. Copper line run to the appliance, surface-clipped where it can be and chased into walls where it cannot, with isolation valves fitted.
- Cylinder and regulator. Cylinder secured in position, regulator fitted, and a changeover valve if two cylinders are used so you do not run dry mid-cook.
- Appliance connection. Hob, stove, geyser or fireplace connected and set for LPG, which is not the same jet configuration as natural gas.
- Pressure test. The installation is tested for soundness before it is signed off, and again after any subsequent alteration.
- Commissioning and handover. Flame checked, appliance demonstrated, and the certificate of conformity issued.
New Installations, Alterations and Extensions
| Type of work | What it means | Certificate |
|---|---|---|
| New installation | No gas at the property before now | New CoC covering the whole installation |
| Extension | Adding a point to existing pipework | New CoC covering the altered installation |
| Alteration | Moving a cylinder, rerouting a line, changing an appliance | New CoC after the change |
| Replacement | Like-for-like appliance swap on the same point | Usually a new CoC, cheap because the pipework already exists |
| Removal | Decommissioning and capping abandoned gas | Documentation that the installation is made safe |
Extensions are where budgets get surprised. Adding a fourth appliance to a line and cylinder that were sized for two often means upsizing both, and the new appliance is then the smaller half of the invoice. Worth asking about before you commit.
Gas Lines and Cylinders
Two decisions drive most of the cost of an installation, and neither of them is the appliance.
- The pipe route. A cylinder outside the kitchen wall with a two-metre run is a cheap installation. A cylinder that has to sit at the side of the house because that is the only compliant position, feeding a hob on the far side, is fifteen metres of copper plus chasing plus making good.
- Cylinder size and count. A 9kg cylinder suits a hob. A geyser plus a hob wants 19kg or 48kg, usually a pair on a changeover so one runs while the other is swapped. Bigger cylinders need a compliant standing position and often a cage.

Ranges are indicative for Cape Town and exclude appliances unless stated. Chasing into brick, tiled surfaces, double-storey routes and heritage-restricted facades all push the number up.

Get Gas Installation QuotesSafety Requirements and Compliance
Fixed LPG installations in South Africa are installed to SANS 10087-1, which sets out cylinder positioning, clearances from openings and drains, pipe materials, ventilation and testing. You do not need to know the standard; your installer does, and the certificate of conformity is their statement that the installation meets it.
- Only a registered authorised person may issue the certificate.
- The installation is pressure tested for soundness before sign-off.
- Appliances must be set up for LPG specifically, not left on natural gas jets.
- Cylinders need a compliant standing position with clearance from windows, doors, drains and boundaries. That position is determined on site, not chosen for looks.
- Rooms with gas appliances need adequate ventilation, which is why a hob in a sealed kitchen sometimes needs a vent added.
Never attempt gas pipework, appliance conversions or cylinder connections yourself. Beyond the safety risk, uncertified work is uninsurable and will fail an inspection when you sell.
Frequently Asked Questions
How much does a gas installation cost in Cape Town?
A single hob on a new supply commonly runs R4,500 to R9,500 including cylinder, regulator, line and certificate but excluding the hob. A hob and geyser sharing one supply is typically R12,000 to R26,000. These are indicative ranges rather than quotations.
How long does a gas installation take?
A hob connected to an existing point is a couple of hours. A new supply with a short pipe run is most of a day. Multi-appliance installations with chased pipework run two to four days, plus a plasterer and painter behind them.
Does the installer supply the cylinder?
Usually yes for the first fill, either bought outright or on a deposit arrangement with a gas supplier. Refills afterwards are yours, from any supplier that stocks that cylinder brand.
Can gas pipes run inside a wall?
Copper gas line is routinely chased into walls, and it is what most people want for the look. It costs more than a surface run and it means plaster and paint work afterwards, so check whether making good is in the quote.
Can I install a gas hob myself and get it certified afterwards?
No installer worth using will certify work they did not do or supervise, and most will refuse outright. Certifying someone else's pipework means taking legal responsibility for joints they cannot see.
What happens if my installation fails the pressure test?
The installer finds the leak and repairs it before the certificate is issued. On a new installation that is their problem and their cost. On an existing installation being recertified, remedial work is quoted separately.
Do I need a new certificate if I only replace the appliance?
Yes. Any change to the installation, including swapping a hob for a different model, means a new certificate. It is cheap on a like-for-like swap because the pipework is already there.
