Pool plumbing electrical decommissioning must be completed before any demolition machine arrives on site: a licensed electrician disconnects the pump circuit and pool light, a licensed plumber caps the water supply and backflow prevention device, and a licensed gasfitter removes the gas connection if a heater is present. These are not optional steps and are not tasks for the demolition contractor or the homeowner to handle.
Quick answer (BLUF)
Three separate licensed trades are potentially involved in decommissioning a pool before removal: electrician (pump and light circuit), plumber (water supply and backflow), and gasfitter (if a gas heater is present). Each must issue a compliance certificate for their work. These costs are part of the pool removal hidden costs checklist that often fall outside a basic demolition quote; confirm with your contractor whether they are included or excluded from the scope.
What needs decommissioning
Before demolition begins, the following services attached to the pool must be properly isolated and capped:
Electrical: pool pump motor circuit (240V or 3-phase on larger pumps), pool light circuit (may be low-voltage or mains-voltage depending on age), and any underwater lighting in the shell. Some older pools also have heating elements and separate circuits for waterfalls or spa jets.
Plumbing: water supply line to the pool (fill valve or auto-fill), pool return lines and suction pipes, backflow prevention device, any water feature supply lines, and the connection to any pool heating solar panels on the roof.
Gas: if the pool has a gas heater (either natural gas or LPG), the gas supply line must be capped and the heater unit removed or rendered inoperable by a licensed gasfitter before any excavation near the gas line.
Chemical dosing: some pools have automatic chlorination or pH dosing systems connected to plumbing. These should be decommissioned and chemical containers removed before site work begins.
All of these services remain live and potentially dangerous until properly isolated. A BYDA check confirms the location of public utility services near the pool, but the pool’s own private services are separate and must be addressed directly.
Licensed electrician: what they do & why they are required
Under the NSW Home Building Act 1989, all electrical work must be carried out by a licensed electrical contractor. SafeWork NSW electrical safety requirements apply to any work on wiring and electrical equipment.
For pool decommissioning, a licensed electrician will:
- Isolate the pool pump circuit at the switchboard and remove the circuit breaker
- Disconnect and cap the pool light wiring, leaving compliant cable terminations
- Confirm isolation with an approved testing device
- Issue a Certificate of Compliance for Electrical Work (CCEW)
The CCEW is an important document: it confirms the electrical work meets the wiring rules and is required by the certifier at sign-off. Keep it with your pool removal paperwork. You can verify any electrician’s licence at the NSW Fair Trading licence check register before work starts.
Do not allow the demolition contractor to cut or pull pool electrical cables without a licensed electrician present. Electrical cable can retain dangerous energy even when a switch is off, and the colour coding of older pool wiring does not always conform to current standards.
Licensed plumber: pool pipework & drainage
A licensed plumber must cap the water supply lines and backflow prevention device before the pool surround is demolished. In NSW, all plumbing work must be performed by a licensed contractor; the plumber must lodge a Notice of Work with NSW Fair Trading before starting and provide a Certificate of Compliance on completion.
For pool removal, a licensed plumber will:
- Cap or remove the auto-fill water supply line at a convenient service point
- Disconnect and cap suction and return pipe connections at the pool shell
- Remove or cap the backflow prevention device
- Manage any rooftop solar heating connections via a plumber or specialist as required
- Issue a Certificate of Compliance for Plumbing and Drainage Work (CCPD)
Keep the CCPD with the project file. Plumbing documentation is relevant if you later sell the property, as a buyer’s solicitor or building inspector may ask about decommissioning evidence.
Licensed gasfitter: pool heaters
Gas pool heaters are common in older Newcastle and Lake Macquarie properties, particularly those installed in the 1990s and 2000s. If your pool has a gas heater (usually a separate unit in the pump equipment area), a licensed gasfitter must:
- Isolate and purge the gas supply at an approved point
- Disconnect the gas appliance (the heater unit)
- Cap the gas pipe to current standards
- Issue a Certificate of Compliance for Gas Work
Gas capping is not a plumbing job, even though gas pipes look similar to water pipes. A licensed gasfitter holds a separate Class B gasfitter’s licence, which can be verified at the same NSW Fair Trading register linked above.
LPG tanks (if a cylinder is used rather than mains gas) must also be managed properly: the cylinder should be turned off and removed or exchanged by a supplier before demolition begins.
Sequencing: what happens when
The decommissioning trades must be coordinated with the demolition contractor to ensure the right sequence is followed. The table below shows the typical order.
| Stage | Who | When |
|---|---|---|
| BYDA enquiry lodged | Contractor or owner | 2-3 weeks before start |
| Council approval received | Certifier | 2-6 weeks before start |
| Licensed electrician disconnects | Licensed electrician | 1-3 days before demolition |
| Licensed plumber caps services | Licensed plumber | 1-3 days before demolition |
| Licensed gasfitter (if applicable) | Licensed gasfitter | 1-3 days before demolition |
| Pool drained | Contractor or owner | 1-2 days before demolition |
| Machine arrives, demolition begins | Demolition contractor | Day 1 |
Trades are typically coordinated by the demolition contractor if they are managing the full project. If you are coordinating trades directly, allow at least a week of scheduling buffer: licensed tradespeople in the Newcastle area are often booked 5-10 business days out.
Trade disconnection costs are part of the broader project budget. For cost context, see the pool removal cost guide and use the pool removal quote comparison guide to confirm whether trades are included or excluded in each quote you receive.
If your pool is a pre-1980 installation, the electrical and plumbing systems may not meet current Australian Standards. An older pool’s wiring in particular may use materials or configurations that require more extensive work to make safe. The asbestos and old pool removal guide covers other legacy material concerns in older installations.
Our full pool removal service coordinates all licensed trade decommissioning as part of the project. The pool excavation and backfill service assumes decommissioning is already complete. Confirm which applies when you review your quote. See how to prepare your property for pool removal day for what needs to be in place before the crew arrives.

FAQs
Can the demolition contractor disconnect pool electrics and plumbing?
No. Electrical disconnection and plumbing cap-off must each be performed by a separately licensed contractor (electrical contractor for electrics, licensed plumber for plumbing, licensed gasfitter for gas). A demolition contractor can coordinate the trades but cannot perform licensed electrical or plumbing work themselves. If a contractor quotes to handle everything without mentioning licensed trades, ask specifically who is doing the disconnection work.
How much does pool electrical disconnection cost in NSW?
Indicative costs for a pool electrical disconnection in the Newcastle and Lake Macquarie area are roughly $300-$700 for a straightforward single-pump, single-light disconnection. More complex installations (multiple circuits, 3-phase pumps, older switchboards requiring new circuit protection) may cost more. Get a specific quote from a licensed electrician before starting.
Do I get a compliance certificate after decommissioning?
Yes. The electrician issues a Certificate of Compliance for Electrical Work (CCEW). The plumber issues a Certificate of Compliance for Plumbing and Drainage Work (CCPD). The gasfitter issues a Certificate of Compliance for Gas Work if applicable. These certificates are required for the final sign-off and should be kept permanently with the property’s records.
Can I turn off the pool pump breaker myself instead of hiring an electrician?
Turning off a breaker is not the same as a licensed disconnection. The circuit is still live to the breaker, and the wiring between the switchboard and the pool is still energised. A licensed electrician isolates the circuit, removes the breaker, and terminates the cable safely. This is the only standard that satisfies the certifier and protects you from liability.
Does pool plumbing decommissioning affect the rest of the house water supply?
Usually not. Pool water supply lines are typically a secondary branch off the main service. A competent plumber can cap the pool supply line without affecting household water pressure or supply. If your pool fill valve is on an unusual configuration, ask the plumber to walk you through their plan before they start.
