Electrical subcontracts in New South Wales: what to check before you sign
In New South Wales, a electrical subcontract is read alongside the Building and Construction Industry Security of Payment Act 1999 (NSW), which caps subcontract payment terms at 20 business days. The contract itself still decides the risks that cost electrical subcontractors most: completion defined as commissioning and certification; variations from late design and coordination; defects liability that restarts.

New South Wales rules that override your contract
Statute: Building and Construction Industry Security of Payment Act 1999 (NSW)
- Payment terms for subcontractors are capped at 20 business days after the payment claim. A longer term in the contract doesn't change that.
- If the builder disputes a payment claim, it has to answer with a payment schedule within 10 business days (or any shorter period in the contract).
- Head contractors must pay subcontractors within 20 business days of the claim, retention money on larger projects must be held in trust, and work can lawfully be suspended after non-payment on two business days' notice.
- Adjudication: typically 10 business days from receiving a payment schedule that disputes the claim, through a private authorised nominating authority.
- Retention on larger projects must be held in trust.
Where electrical subcontractors lose money
Completion defined as commissioning and certification
If practical completion for your package needs the whole building energised, tested and certified, your liquidated damages clock runs while you wait on the authority, the HV upgrade or another trade's equipment. Define your completion by your own scope.
Variations from late design and coordination
Electrical design moves with every architectural and services change. A short or absolute notice window on variations means the redesign you absorbed on site becomes free work. Check the notice period and whether a written direction is required before you start.
Defects liability that restarts
Fittings and equipment fail for reasons outside your workmanship. A defects liability period that restarts on every rectification can keep your retention locked up well beyond the usual 12 months.
Supply risk on long-lead equipment
Switchboards, generators and specialist fittings can have long lead times. If the contract puts all supply delay on you with no extension of time, a manufacturer's delay becomes your liquidated damages.
Three things to push for in your departures schedule
- Completion of the electrical works defined by your scope, not whole-of-building commissioning
- A notice period for variations of at least 5 business days, as a notice requirement rather than an absolute bar
- Extension of time for supply delays outside your control, with the manufacturer's notice as evidence
The free scanner finds these clauses in your actual contract in about two minutes and writes the departures schedule for you.
What the Index says
Live figures from the Australian Subcontract Index, 90 real subcontracts. The Index holds only 8 electrical contracts so far, under the 10-contract threshold, so these are national figures across all trades. Nothing under 10 contracts is ever shown.

Electrical subcontracts in NSW: common questions
How long does a builder in NSW have to pay a electrical subcontractor?
No more than 20 business days after your payment claim, whatever the contract says. If the builder disputes the claim, it has 10 business days to answer with a payment schedule giving its reasons.
Can a builder hold an electrician's retention until the whole building is certified?
Only if the subcontract says so, which is why the release trigger matters. Market practice is half at practical completion of your works and half at the end of the defects period. A trigger tied to the head contract's completion or final certificate can hold your money for years.
Where do NSW electrical payment disputes go?
Authorised Nominating Authorities (NSW Fair Trading maintains the list). Timing: typically 10 business days from receiving a payment schedule that disputes the claim, through a private authorised nominating authority.
