Gas Line Installation Cape Town is the pipework between the cylinder and the appliance. It is the part of a gas installation nobody thinks about when they are choosing a hob, and it is frequently the larger half of the bill.
New runs, extensions to reach a new appliance, rerouting around a renovation, and replacing old line that has failed an inspection.
Tell us where the cylinder is and where the appliance needs to be. Rough metres is enough to start.
Get Gas Line Installation QuotesWhat Gas Line Costs Depend On
| Factor | Cheaper | More expensive |
|---|---|---|
| Route | Surface-clipped along an external wall | Chased into internal brick and plastered |
| Distance | Under 5 metres | 15 metres or more, or across a double storey |
| Diameter | Single appliance | Sized for simultaneous multi-appliance draw |
| Obstacles | Open wall, easy access | Tiled splashbacks, built-in units, screeded floors |
| Finishes | Face brick or painted plaster | Cladding, stone, heritage facade |
| Making good | Not required | Plaster, skim and paint behind the installer |
The honest version: an installer standing in your kitchen can see in thirty seconds whether this is a R3,000 run or a R14,000 one, and no amount of describing it over the phone gets you the same accuracy.

Compare Gas Line QuotesResidential and Commercial Runs
Domestic lines are short, single-appliance or lightly branched, and almost always copper. Commercial reticulation is a different animal: a manifold feeding a bank of appliances, each with its own isolation, sized for everything firing at once during service, and frequently with an emergency shut-off at the kitchen exit. If your job is commercial, Commercial Kitchen Gas Installation Cape Town covers the difference properly.
Planning a Line Before the Builder Closes the Walls
If you are renovating, get the gas installer in before the plasterer. Chasing a wall that is already tiled costs several times what it costs to run pipe into an open one, and the result looks better. Points that are worth roughing in even if the appliance comes later:
- The hob position, plus a capped point for a wok burner if the kitchen might grow into one
- A geyser point on the external wall nearest the bathrooms
- An outdoor point at the braai area, capped until the braai is bought
- A fireplace point in the lounge, which is nearly impossible to add cheaply later
- The cylinder position, with the standing area, screening and any cage allowed for
A capped point roughed in during a renovation costs a fraction of retrofitting it. It also has to be included on the certificate, so tell your installer it is there.
Existing Lines That Fail
Older Cape Town installations throw up the same handful of problems on inspection: pipe run without the right support so it sags and stresses joints, flexible hose used where rigid pipe belongs, no isolation valve at the appliance, line passing through a cavity without a sleeve, and corrosion on external copper in coastal suburbs. Most are repairable without replacing the whole run, but the installation cannot be certified until they are.
Frequently Asked Questions
How much does gas line installation cost per metre in Cape Town?
Surface-run copper commonly costs R450 to R700 per metre installed, and chased into a wall R650 to R950 per metre excluding plaster and paint. Short runs carry a minimum charge that makes the per-metre figure misleading below about five metres.
What pipe is used for LPG gas lines?
Copper tube is standard for fixed domestic installations, with approved fittings and, where appliances need flexibility, a short approved flexible connector at the appliance itself. Ordinary plumbing hose and general-purpose fittings are not acceptable on gas.
Can a gas line run under a floor or underground?
Yes, with the correct sleeving and protection, and it is common where a cylinder position is across a courtyard from the house. It costs considerably more than an above-ground run and it needs excavation, which is normally your builder's cost rather than the installer's.
Can I extend my own gas line to a new braai point?
No. Alterations to a fixed gas installation must be done by a registered installer, and the installation has to be pressure tested and re-certified afterwards. Uncertified alterations invalidate the existing certificate and will be picked up when you sell.
Does adding an appliance always mean a new gas line?
Not always. If the existing line has spare capacity and runs near the new appliance, a branch and an isolation valve is enough. If the line was sized for one appliance, adding a second usually means replacing the run.
How long does a gas line installation take?
A short surface run is a few hours. A chased run through a finished house is one to two days, plus the plasterer and painter afterwards. Under-slab and external routes depend entirely on how quickly the excavation happens.
