Quick answer: Maintenance work requires a SWMS when it meets the definition of construction work under the WHS Regulations and involves at least one High Risk Construction Work category, such as working at height, confined spaces, or work near energised electrical installations. Where a SWMS is not legally required, a safe work procedure or risk assessment is still good practice.
Last reviewed: June 2026 by the BlueSafe Technical Team. Reflects current Australian WHS requirements.
Maintenance work sits in one of the most commonly misunderstood areas of Australian WHS law. Many businesses assume that because a task is routine, it does not attract the same obligations as a new construction project. That assumption can be costly. The trigger for a SWMS is not how familiar the job is — it is what the work involves and whether it meets the legal thresholds for High Risk Construction Work.

The two-step legal test
Before you can answer whether a maintenance task needs a SWMS, you need to apply two questions in sequence.
Step 1: Is it construction work?
Under the WHS Regulations, construction work includes the installation, repair, maintenance, alteration, or removal of any structure. The definition is broad. Replacing roof sheeting, servicing mechanical plant on a rooftop, repairing structural elements, or maintaining plant that is part of a structure can all fall within it.
Step 2: Does it involve High Risk Construction Work?
If the task is construction work, you then check whether it involves any of the High Risk Construction Work categories. If it does, a SWMS is required before the work starts.
Both steps must be satisfied. If the task is not construction work at all, the SWMS obligation does not apply — though other safety obligations still do.
Common HRCW categories that appear in maintenance
Many maintenance tasks regularly trigger HRCW categories. The most common ones include:
- Working at height — any work where there is a risk of a person falling more than 2 metres, such as working from ladders on a roof, maintaining elevated plant, or cleaning gutters at height
- Confined spaces — entering tanks, pits, ducts, or enclosed areas to carry out repairs, cleaning, or inspection
- Work on or near energised electrical installations — including live switchboard work, cable maintenance, or any task close to energised conductors
- Asbestos disturbance or removal — maintenance of older buildings frequently disturbs materials that contain or potentially contain asbestos
- Trenching and excavation — maintenance of underground services, drainage repairs, or similar excavation deeper than 1.5 metres
If a maintenance job involves any of these, stop and ask whether a SWMS has been prepared.
Routine maintenance vs construction work
The distinction between routine maintenance and construction work is not always obvious, and the label businesses put on a task does not change its legal classification.
A task that is performed regularly and is familiar to the crew can still be High Risk Construction Work. Familiarity reduces the chance of error over time, but it does not remove the hazard. A tradesperson who services rooftop air conditioning units every week is still working at height every week.
Genuine routine maintenance that falls outside the construction work definition — such as lubrication, filter replacement, or visual inspection carried out at ground level and away from energised parts — is unlikely to trigger SWMS obligations. But once the task involves structural elements, plant that forms part of a structure, or access at height or into confined spaces, the analysis changes.
When in doubt, err on the side of completing a SWMS. The effort is low; the consequences of getting it wrong are not.
When a SWMS is not legally required
Not every maintenance task will reach the SWMS threshold. Where a SWMS is not required, that does not mean the work can proceed without any safety planning.
Under the WHS Act, every PCBU has a duty to eliminate or minimise risks so far as is reasonably practicable. For lower-risk maintenance work, that duty is still met through:
- a documented safe work procedure setting out how the task should be performed
- a risk assessment identifying hazards and the controls in place
- a permit to work where site rules or the nature of the hazard require one (for example, hot work or isolation of plant)
The difference between a SWMS and these alternatives is explained in more detail in Safe Work Procedures vs SWMS.
Good practice is to document your thinking even when you conclude a SWMS is not required. A brief written record showing that you assessed the task and the controls in place protects both workers and the business.
Contractor maintenance work
When maintenance is performed by contractors rather than direct employees, the SWMS obligations shift — but do not disappear. The principal contractor or PCBU who engages the contractor must:
- confirm that SWMS obligations have been identified before work starts
- ensure the contractor has prepared a compliant SWMS where HRCW is involved
- not direct work to commence if the required SWMS is not in place
Contractors performing maintenance are themselves PCBUs and carry their own duty to prepare a SWMS for any HRCW they carry out. Both parties share responsibility for ensuring compliance, regardless of how the contract is structured.

Frequently asked questions
Does all maintenance work require a SWMS?
No. A SWMS is only legally required when the maintenance task meets the definition of construction work under the WHS Regulations and involves a High Risk Construction Work category. Routine maintenance performed at ground level and away from HRCW hazards generally will not trigger the obligation.
What makes maintenance work count as construction work?
The WHS Regulations define construction work to include the repair, maintenance, alteration, or installation of any structure. The definition covers more than traditional building projects. Many maintenance tasks — particularly those involving plant attached to structures, roof access, or below-ground services — fall within it.
What if my maintenance task does not require a SWMS?
The absence of a SWMS obligation does not remove the duty to manage risk. A safe work procedure or risk assessment is still good practice and may be expected by your principal contractor or site management. Documented controls also help demonstrate that the business has met its duty of care.
Who decides whether a maintenance task is HRCW?
The PCBU is responsible for making that assessment before work starts. In practice, a competent supervisor, safety advisor, or contractor manager applies the two-step test: is this construction work, and does it involve an HRCW category? Workers should be consulted as part of that process.
