Vetting and Police Checks for Night-Shift Cleaners

The people who clean your office after hours often have more unsupervised access to your building than most of your own staff. They enter when the building is empty, move through every room, and are trusted to leave it secure. That makes vetting one of the most important and least visible parts of a cleaning contract. A cheap quote built on unvetted casual labour is not really cheaper — it has simply moved a risk onto your balance sheet without telling you.

This article sets out what genuine vetting looks like for night-shift cleaners, why a police check on its own is only part of the picture, and how to check that a contractor's screening is real rather than a line on a website.

Why vetting matters more for after-hours work

Vetting scales with trust, and after-hours cleaning involves a lot of trust. During the day, a cleaner works among staff who would notice unusual behaviour. At 2am, the cleaner may be the only person in the building, with access to desks, documents, and equipment and no one watching. That is not a reason to distrust cleaners; it is a reason to make sure the people doing the work have been properly checked before they are given that level of access.

The goal of vetting is straightforward: to have reasonable confidence that the individuals entering your building are who they say they are, are entitled to work, and have no known history that makes unsupervised access unwise. No screening process is a guarantee, but a layered one materially reduces the risk.

The layers of proper vetting

Vetting is best understood as several checks that reinforce each other, not a single document.

• Identity verification — confirming the person is who they claim to be, using government-issued identification.
• Right-to-work verification — confirming the person is legally entitled to work in Australia.
• National police check — a criminal history check appropriate to unsupervised access roles.
• Reference and employment history — confirming past work and character with previous employers.
• Onboarding and training records — evidence the person has been inducted into the contractor's procedures.

A contractor who does all of these has a defensible screening process. One who relies solely on a police check has a partial one, and one who does none is exposing you to whatever walks through the door.

Why a police check alone is not enough

Police checks are valuable, but they have limits worth understanding. A check reflects a person's recorded history at a single point in time; it says nothing about the period since, and it does not verify identity, work rights, or reliability. Relying on a police check alone can create a false sense of security — the box is ticked, but several other risks remain unaddressed.

This is why serious contractors treat the police check as one layer among several and pair it with a renewal cycle. Combined with identity checks, references, and ongoing supervision, the police check becomes part of a picture rather than the whole of it.

Keeping vetting current

A vetting process that runs only at hire and is never revisited slowly loses value as rosters change and time passes. Good contractors maintain currency in a few ways: refreshing police checks on a defined cycle, re-verifying details when someone returns after a break, and — most importantly — supervising staff continuously so that concerns are noticed and acted on. Continuity of crew helps here too. A stable, long-serving team is easier to manage and monitor than a stream of unfamiliar casuals, and familiarity is itself a quiet form of ongoing vetting.

How to verify a contractor's vetting

You cannot see individual results — nor should you, as those remain confidential — but you can and should verify the process. The table below sets out what to ask for and what a good answer looks like.

What to ask	Good answer	Warning sign
"What is your screening policy?"	A written policy covering all layers	"We check everyone" with no detail
"Are checks held for our site's staff?"	Yes, confirmed for named crew	Vague or deferred answers
"How current are the police checks?"	Recent, with a renewal cycle	Checks of unknown age
"Do you verify right to work?"	Yes, as standard onboarding	Not mentioned or unsure
"Who supervises the night crew?"	Named supervisor and process	No clear oversight

The point of these questions is not to catch the contractor out but to distinguish a real process from a marketing claim. A provider who takes vetting seriously will welcome them, because it is exactly the standard they hold themselves to.

Vetting as part of the wider security picture

Vetting does not operate in isolation. It works alongside the other controls in an after-hours arrangement — named credentials, access logs, close-down routines, and clear reporting. Well-vetted staff following weak procedures still create risk, and strong procedures applied by unvetted strangers do too. The two reinforce each other, which is why the strongest arrangements treat vetting and operational controls as a single system rather than separate checkboxes.

It is also worth being realistic about what vetting can and cannot promise. Screening reduces the likelihood of employing someone unsuitable and demonstrates that reasonable care was taken; it cannot guarantee that no incident will ever occur. Framing it honestly — as risk reduction and due diligence rather than a guarantee — keeps expectations sensible on both sides.

Making vetting a contract requirement

The most reliable way to secure proper vetting is to write it into the service agreement. Specify that all staff assigned to your site have been through identity, right-to-work, and police checks, that checks are refreshed on a defined cycle, and that the contractor will confirm compliance on request. That turns vetting from an assurance into an obligation, and gives you a clear basis for review.
