Yes, gas bayonet points are legal in NSW when a licensed gasfitter installs them to AS/NZS 5601.1:2022 and issues the correct compliance paperwork on completion. Get any of that wrong and you’re carrying real legal and safety risk. The three non-negotiables are simple: only a licensed gasfitter can touch the job, the fitting must sit in a permitted location with proper clearances, and you need a signed certificate before the tools pack away.
TL;DR:
- Only licensed gasfitters can legally install gas bayonet points in NSW, and they must provide a signed compliance certificate after correct siting and certification.
- Bayonet points are prohibited in bedrooms, bathrooms, toilets, hallways, garages, and must be placed at least 1 meter from doorways, with outdoor points 300mm above ground and secured with a safety chain.
- Ventilation must be assessed before connecting high-output heaters to ensure safe operation, especially in small or enclosed rooms, with no points awarded for unflued portable heater installations.
- Failing to obtain or produce a compliance certificate can result in fines up to $55,000 for individuals or $550,000 for companies, with enforcement often occurring through audits or routine inspections.
- Homeowners should verify licensing before installation, request a compliance certificate immediately, and keep all paperwork for legal and insurance purposes.

What NSW gas safety laws require before anyone connects a bayonet
Homeowners often assume a bayonet point is a minor plumbing job. It isn’t. Under the Gas and Electricity (Consumer Safety) Act 2017, all gasfitting work in NSW, including bayonet installation, must be carried out by an appropriately licensed gasfitter. Doing it yourself, or hiring an unlicensed handyman, breaches the Act outright.
The technical rulebook sitting underneath that law is AS/NZS 5601.1:2022, the current Australian standard covering gas installation, siting, ventilation, and appliance connection. NSW regulation points directly to this standard for bayonet compliance, and the Gas and Electricity (Consumer Safety) Regulation 2018 fills in the detail on certification and enforcement.
Before you sign off on any quote, confirm the person doing the work actually holds a current licence:
- Check the tradesperson’s licence through NSW Fair Trading’s online lookup or by calling 13 27 00.
- Ask for the licence number in writing before work starts, not after.
- Confirm they intend to issue a compliance certificate, not just a receipt.
A five-minute licence check costs nothing. A botched, unlicensed connection can cost you your insurance claim if something later goes wrong.
Where a bayonet point can and can’t legally go
Siting is where most non-compliant installations get caught out, and the rules are specific rather than a matter of common sense. The Building Commission NSW advisory note sets out exactly where a connection point may and may not be fitted.
- Bayonet points must never be installed in bedrooms, bathrooms, saunas, toilets, hallways, or residential garages.
- The fitting must sit at least 1 metre clear of any doorway, and out of paths people regularly walk through.
- Outdoor bayonets need to be at least 300mm above ground level to avoid water ingress and physical damage.
- Outdoor installations must include provision for a safety chain to secure a portable heater or appliance in place.
- The point must be positioned so a hose assembly can connect without kinking, stretching, or crossing a walkway.
Hallways and garages come up again and again in audits precisely because they’re the rooms where people want to run a heater in winter. Convenience doesn’t override the standard.
Ventilation and appliance limits you can’t ignore
A bayonet point exists to power an appliance, usually a portable heater, and that appliance’s ventilation needs are part of the compliance picture, not an afterthought. AS/NZS 5601.1:2022 sets minimum ventilation requirements based on room volume and the appliance’s gas consumption rating, and a licensed gasfitter should be assessing this before connecting anything.
- Larger, higher output heaters need proportionally more fresh air exchange in the room.
- Small, enclosed rooms with a bayonet point often can’t legally support a high consumption unflued heater.
- Ventilation is normally assessed against the room’s dimensions and any existing fixed openings.
Here’s a figure worth knowing: BASIX energy assessments don’t award any points for installing a gas bayonet, because they’re typically paired with unflued portable heaters. NSW Health flags the same appliances as a genuine indoor air quality concern. A bayonet is a convenience fitting, not an efficiency upgrade, and it shouldn’t be marketed to you as one.
Certificates and paperwork you must keep
Once the work is done, the paperwork is what actually proves it was done legally. A licensed gasfitter must issue either a certificate of compliance for network gas connections or a certificate of inspection for bottled gas installations.
- The certificate must name the licensed gasfitter, their licence number, and the exact scope of work completed.
- Network gas certificates are typically lodged through the Building Commission NSW eCert system, giving you a digital record.
- Landlords should keep a copy on file indefinitely, not just until the next inspection, since it matters for tenancy disputes, insurance claims, and property sale disclosures.
If a gasfitter hesitates to provide this, treat it as a red flag rather than an oversight.
Penalties for unlicensed or non-compliant gas work
Regulators in NSW aren’t gentle about this. Breaching the Gas and Electricity (Consumer Safety) Act 2017 carries fines up to $55,000 for individuals and $550,000 for corporations on a first offence, with steeper penalties and the possibility of imprisonment for repeat breaches.
- Unlicensed installation work is one of the most common triggers for enforcement action.
- Selling or connecting non-approved appliances to a bayonet point is another frequent audit finding.
- Bayonets sited in prohibited rooms, particularly garages and hallways, show up repeatedly in Building Commission NSW audits.
Enforcement doesn’t only happen after a complaint. Strata inspections and routine building audits catch a large share of non-compliant fittings before anyone reports a fault.
Your compliance checklist for installing or inspecting a bayonet
Whether you’re commissioning a new bayonet or checking one that’s already there, work through this in order.
Before work starts:
- Verify the gasfitter’s licence through NSW Fair Trading.
- Ask which standard they’re working to and get AS/NZS 5601.1:2022 named in writing.
- Request a ventilation assessment for the intended room before any appliance is connected.
During installation:
- Confirm the proposed location isn’t a bedroom, bathroom, toilet, hallway, or garage.
- Check clearance from doorways and, for outdoor points, the 300mm height and safety chain provision.
- Watch for the correct certificate being prepared on-site, not promised for later.
After the job:
- File the compliance certificate somewhere you can find it in five years, not just this month.
- Book a seasonal gas heater and fitting safety check before each winter.
- Keep photographic evidence of the installed fitting for tenancy handovers or a future property sale.
Pro Tip: If you’re a landlord managing several properties, keep a single folder, digital or physical, with every gasfitting certificate on file. When a tenant disputes a repair or an insurer asks questions after an incident, that folder is the difference between a five minute resolution and a drawn out claim.
What tradespeople actually find on site in Sydney
Audits and call-outs turn up the same mistakes repeatedly: bayonets fitted in garages to run a portable heater, points placed too close to a doorway, and certificates that were promised but never delivered. None of these are complicated to avoid.
Asking for the certificate before the fitter leaves, not after a follow-up call, saves homeowners weeks of chasing paperwork. Getting siting right the first time also cuts down on the emergency call-outs that come from appliances running in poorly ventilated spaces.
