Gas fitting on the upper
North Shore

Because gas pipe has to be sized for the appliance at the end of it and for the distance it travels. A long run needs a larger diameter to deliver the same pressure, so on a bigger property the distance from the meter is doing as much to set the specification as the appliance is. It is also, straightforwardly, more pipe and more labour.

Sometimes, and it is worth checking rather than assuming. Adding an appliance is a capacity question: the existing pipe was sized for what was on it at the time. On a long run there is frequently less headroom than people expect, so we work it out before anything is ordered.

Get everyone outside first. Do not touch any switch, do not use a phone indoors, and if the meter is safely on your way out, turn it off. Then ring from outside.

The document a licensed gasfitter issues certifying the work was done to standard. It is legally required and it is the only durable record the job was done properly. Keep it with the house papers, because insurers ask for it and so does a conveyancer at sale.

It is worth resolving rather than wondering about. We can pressure test the installation and tell you plainly what state it is in, which costs very little against what it settles, particularly before a sale.

No. Gas is licensed work in NSW with no exemption for a small job or a capable owner. Unlicensed work cannot be certified, voids a home insurance claim, and leaves nothing on record showing it was ever safe.

A leak test on the installation is $150 to $300. A cooktop connected and certified is $250 to $500. A new gas point run and certified is $450 to $1,200, and on a longer run it sits toward the upper end for the reasons above. A heater bayonet is $300 to $600.
