Insurance and Liability for After-Hours Office Cleaning

Insurance is the part of a cleaning contract that everyone assumes is handled until the day it is not. A cleaner slips on a wet floor, a piece of equipment damages a fit-out, water from a cleaning task reaches a tenant below, or an item goes missing overnight. In each case the first question is the same: who carries the risk, and is there cover behind it? For after-hours office cleaning, where the work happens unsupervised in an empty building, these questions deserve to be settled before the first shift, not discovered after an incident.

This article explains the main insurance and liability considerations for after-hours office cleaning and how to verify cover properly. It is general information rather than legal or insurance advice; for your specific situation, take advice from your broker or adviser.

Why liability sits closer to you than you think

When you engage a cleaning contractor, you are inviting a third party to work inside your premises, often when no one else is there. Things can go wrong, and when they do, the cost lands somewhere. A well-structured arrangement makes sure it lands on the party best placed to carry it — usually the contractor and their insurer — rather than defaulting to you because no one checked the cover.

The risk of skipping this is quiet but real. A cheap quote from an uninsured or underinsured contractor can look attractive right up to the moment an incident occurs, at which point the apparent saving is dwarfed by a cost you now carry yourself. Verifying insurance is one of the highest-value pieces of due diligence you can do, and it takes very little time.

The core covers to look for

A few types of cover are central to office cleaning. The table below summarises what each is broadly intended for and why it matters.

Cover	Broadly intended for	Why it matters to you
Public liability	Third-party injury or property damage caused by the contractor	Responds if cleaning causes damage or injures a third party
Workers compensation (WorkCover)	The contractor's own staff injured at work	Confirms staff injuries are the contractor's cover, not your exposure
Property / equipment	The contractor's own equipment	Their tools are their responsibility, not yours

Public liability and workers compensation are the two you should always confirm. The appropriate amount of public liability cover depends on your building and the value at risk; many commercial arrangements expect cover in the millions, and building management in a tower may specify a minimum. Workers compensation is a legal requirement for employers in Victoria, so a contractor employing staff should hold it as a matter of course.

Verify, do not assume

The single most important habit is to ask for evidence rather than take cover on trust. Request current certificates of currency for public liability and workers compensation, and check three things on each: that the cover is current and not expired, that the insured entity matches the contractor you are actually engaging, and that the amounts are adequate for your building. Diarise the expiry dates and ask for renewed certificates when cover rolls over, so a lapse does not go unnoticed. A reputable contractor produces these documents without fuss; reluctance or vagueness is itself a warning sign.

Employees versus subcontractors

One detail that materially affects liability is whether the people cleaning your office are the contractor's employees or subcontractors, and whether any labour is casual or outsourced. This matters because it affects who is covered by what. A contractor who employs and directly manages a stable crew presents a clearer insurance and liability picture than one who assembles casuals or subcontracts the work to third parties whose cover you cannot see. Ask directly how the workforce is structured and whether everyone on your site is covered under the certificates you have been shown. Where subcontracting is involved, confirm that it does not create a gap in cover.

Setting responsibilities in the contract

Insurance responds to incidents, but the contract sets expectations, and the two work together. A well-drafted service agreement should state the insurance the contractor must hold and maintain, require certificates to be provided and kept current, set out how property damage and incidents are reported and handled, and clarify responsibilities between the parties. This does not replace insurance — it makes claims cleaner by removing ambiguity about what was agreed. It also protects the contractor, who knows exactly what they have committed to.

Where your building is a managed tower, building management may impose its own insurance requirements on contractors working after hours. Make sure your contractor meets both your requirements and the building's, so there is no conflict on the night.

Incidents and claims: making them straightforward

Even with good cover and a clear contract, the way an incident is handled shapes how smoothly a claim proceeds. Agree in advance that damage or injury is reported promptly, documented at the time with dates and details, and escalated to the right contacts. A photographed, logged incident reported the same night is far easier to resolve than one reconstructed weeks later. This ties back to the reporting and escalation procedures that should already sit within your after-hours arrangement — insurance is the financial backstop, and good reporting is what lets it work as intended.

A sensible pre-start checklist

Before an after-hours contractor starts, settle the insurance and liability basics: obtain current public liability and workers compensation certificates, confirm the amounts suit your building and any building-management minimums, understand how the workforce is structured, and make sure the contract sets out cover, reporting, and responsibilities. None of this is onerous, and doing it once at the outset avoids the far larger cost of discovering a gap after something has gone wrong.

Insurance cannot prevent incidents, and no arrangement should be sold as risk-free. What proper cover and clear contractual responsibilities do is make sure that when something does go wrong, the cost falls where it should and the response is orderly rather than contested.
