What to Do When Your Cleaner Finishes Suspiciously Early

You are paying for two hours a night. The car is gone by twenty past nine. Nobody wants to be the person who accuses a cleaner of anything, so the thought just sits there for weeks.

Here is the answer before the detail. Before you treat a cleaner finishing early as a problem, find out whether you bought hours or bought outcomes.

Most Dublin cleaning contracts are priced against a written specification, not against a timesheet. If the specification is being met, speed is not a breach. If your agreement does state hours on site, this turns into a straightforward billing conversation, and there is a fair way to have it without anyone being accused of anything.

Quick answer: Before treating an early finish as a problem, check whether your cleaning contract is priced on hours or on an agreed specification. If it is output-based and the specification is being met, speed is not a breach. If it is hours-based, compare your floor area against production rates of roughly 300 to 450 square metres per hour for general office areas.

Hours or outcomes? Read your contract first

Pull out the quote, not the invoice. The wording on the original quote tells you almost everything.

If it says something like "two hours per night, Monday to Friday, at €X per hour", you have an input-based contract. You bought time. If it says "nightly office clean as per attached specification, €X per month", you have an output-based contract. You bought a result.

Most Dublin commercial contracts we take over are output-based, even when the client believes otherwise. The hours were mentioned once during the sales visit, never written down, and then remembered as a promise.

That is not always the contractor being slippery. It is usually nobody writing it down.

Neither model is better. The problem is holding an output-based contract to an input-based expectation, or the reverse. If you want time guaranteed, it has to be written as time, and the hourly rate for commercial cleaning has to be agreed in the same document.

Speed is not evidence: why a cleaner finishing early is often a good sign

An experienced operative is genuinely much faster than an inexperienced one. Not slightly. Substantially.

The difference is not effort. It is method. A trained operative works top down, dry tasks before wet, and backwards towards the exit so nothing is walked over twice. The trolley is pre-loaded before the first door opens, so there are no return trips to the store.

Cloths are colour-coded and folded to eight faces, so one cloth covers a run of desks without a rinse stop. Chemicals are sprayed and left to dwell while other work happens, rather than sprayed and immediately wiped. Nothing gets re-done, because it was done correctly the first time.

Across our own teams, the gap between a trained operative and an untrained one on identical work at identical quality runs at roughly 30 to 40 per cent. That is a real number from real sites, and it is why the fastest way to clean an office building is sequence and preparation, not rushing.

So the fast finish may be the best thing happening in your building. Removing a quick, thorough operative and replacing them with someone who fills the full two hours and does less is a costly and surprisingly common mistake. Judge the result on the floor, not the clock on the wall.

The check that actually matters is whether the low-visibility work is being done. If skirtings, chair bases and behind-the-door areas are being skipped while the desks gleam, that is a different problem entirely — see our companion piece on why cleaners keep missing the same areas, and we cover the same pattern from the "visible only" angle in what to do when only the visible areas are being cleaned.

Do the maths for your building

This is the part that settles most arguments. Below are the numbers we price from when we survey a site in Dublin. They vary with furniture density, floor type and how detailed the specification is, but they are close enough to test a suspicion with.

A six-cubicle washroom block done properly is rarely under 45 minutes. That single line ends more disputes than any other in this article — if washroom quality is also part of your complaint, our guide on staff complaining about dirty washrooms covers the frequency side of that conversation.

The worked example

Take a realistic Dublin site: 600 m² of open plan, two six-cubicle washroom blocks, a small kitchen and a reception.

• Open plan, 600 m² at 400 m² per hour: 90 minutes
• Two washroom blocks at 45 minutes each: 90 minutes
• Kitchen: 20 minutes
• Reception, matting, glass and lift: 15 minutes
• Subtotal: 215 minutes
• Add 10 per cent for set-up, trolley prep, the waste run to the bin store and lock-up: 22 minutes
• Total: roughly 237 minutes, just under four hours of operative time

One person cannot deliver that building to a proper daily specification in two hours. Two operatives for two hours each can. If your contract says "two hours a night" and means one person, the arithmetic was never there, and the early finish is a symptom rather than the cause.

That 10 per cent matters more than people expect. A cleaner's contracted time includes signing in, loading the trolley, changing mop heads, the walk to the bin store, checking the alarm and locking up. None of it shows on a desk, and all of it is paid.

Your own time budget

Fill this in for your building before you raise anything. It takes fifteen minutes and it is the single most useful document you can bring to the conversation.

One cost check to run alongside it. Under the Contract Cleaning Employment Regulation Order, S.I. No. 430/2025 (Employment Regulation Order (Contract Cleaning Industry Joint Labour Committee) 2025), the adult rate is €14.80 per hour from 1 January 2026. You can also read the full ERO instrument on the Irish Statute Book. Add employer PRSI, 8 per cent holiday accrual under the Organisation of Working Time Act 1997, the ERO sick pay scheme and pension auto-enrolment, and the true cost of an hour on site is well above the headline rate.

So if the monthly price divided by the promised hours lands anywhere near €14.80, the hours are not being delivered. A contractor pricing hours they cannot fund is either losing money or quietly shortening the visit. Neither ends well for the client. The same arithmetic is worth running before you agree what one hour of office cleaning should cost.

How to verify time on site, fairly and lawfully

Work up the ladder. Start with what you already have and what the contractor can simply tell you.

• ☐ Ask the contractor in writing for the operative's scheduled shift times for your site
• ☐ Check the sign-in book at reception that you already keep for fire roll-call
• ☐ Check your alarm set and unset times, which most Dublin offices already log for insurance
• ☐ Ask the contractor for their own time and attendance record, since many now run a phone check-in per visit
• ☐ Tell the contractor you are reviewing time on site before you start reviewing it

That last point is not politeness. It is the position.

Monitoring a contractor's staff is monitoring workers, and the same principles apply as if they were your own employees. Under GDPR and Irish data protection law, any monitoring has to be lawful, proportionate and transparent, and covert monitoring is very difficult to justify.

In practice: reviewing access control and alarm logs you already hold for security purposes is generally fine, because that processing already exists for a stated reason. Installing a camera specifically to watch a cleaner, or pulling CCTV for that purpose without notice and a stated basis, is not a step to take without advice.

If you are anywhere near that line, read the Data Protection Commission guidance on monitoring in the workplace and talk to your own advisor first. The Health and Safety Authority is a useful second reference if the review also touches on lone working or shift-time welfare rather than data protection alone. Transparency is both the legal position and the better tactic. A contractor told openly that you are checking attendance will usually hand over the records the same week.

What the answer usually turns out to be

We have been on both sides of this conversation, including as the incoming contractor asked to explain the last one. In almost every case the cause is one of four things, and none of them is theft.

1. The specification is smaller than you believe. A client in Sandyford was certain they were being short-changed at 90 minutes a night. We ran the time budget on survey. The 90 minutes was correctly priced, because the scope had been trimmed two years earlier during a cost-saving round that nobody had told the current office manager about. Alternate-day vacuuming, no internal glass, no kitchen floor machine. The contractor was delivering exactly what was signed. The fix was a scope conversation, not a complaint — the same kind of gap our guide to what a proper office cleaning specification should cover is built to catch.
2. The hours were priced to win the tender. The contractor quoted a number that looked good on the sheet and was never fundable. Ask for hours per visit in writing and run the ERO check above.
3. The operative has a second site and a fixed travel window. Common on early-evening rounds. The fix is a schedule change, not a new cleaner. Ask for a later start or a split shift. This is closely related to the churn we cover in a cleaning contractor sending a different person every week.
4. Periodic tasks were never scheduled. Daily work genuinely takes 90 minutes, the price covers two hours, and the difference was meant to cover monthly detail work that nobody diarised. Get a written periodic schedule with dates. If it has been years, a proper deep clean of the office may be the honest reset.

The conversation, and what to ask for

Keep it with the contractor, never with the operative on site. The operative is following an instruction sheet they did not write. If the issue turns out to be about the person rather than the schedule, our note on how cleaning standards can slip a few months into a new contract has a similar diagnostic structure you can reuse.

Ask for three things in one email:

1. The scheduled shift times for your site, in writing
2. The current specification, as signed, with any amendments
3. Confirmation of whether the price is hours-based or output-based

Put the shift schedule and the specification side by side. Nine times out of ten the answer is visible in ninety seconds.

If it is output-based and the spec is being met, you have your answer and you keep a fast operative. If it is hours-based and the hours are short, ask for the missing time to be delivered as periodic work rather than credited. A quarterly carpet clean or a full washroom descale is usually worth more to the building than a small refund. Where the billing itself does not line up, that is a separate trail, and an invoice that does not match the scope needs its own paperwork.

For a sense of what a longer visit should actually contain, what to expect from a 3 hour clean sets out a realistic task list.

Frequently asked questions

How long should it take to clean a 500 square metre office? For a general open-plan 500 m² area on a daily specification, allow roughly 70 to 100 minutes for one operative. Add the washrooms, kitchen and reception separately, then add 10 per cent for set-up and lock-up. Cellular layouts with desks to work around sit at the slower end of that range.

Can I check what time my cleaner arrives and leaves? You can, using records you already hold for another purpose, such as sign-in books and alarm set and unset logs. Tell the contractor you are doing it. Monitoring a contractor's staff is monitoring workers, so it must be lawful, proportionate and transparent. Check the Data Protection Commission guidance and take your own advice before anything covert.

Is my cleaning contract based on hours or on results? Look at the original quote. A stated hourly rate multiplied by attendance means input-based, so hours are what you bought. A monthly fee against an attached specification means output-based, so the task list is what you bought. If the quote is silent on hours, it is almost always output-based in practice.

Is it normal for a cleaner to finish early? Yes, and often it is a sign of a well-trained operative. Correct sequence, a pre-loaded trolley and proper dwell times make a trained cleaner 30 to 40 per cent faster at identical quality. Judge the finished result against the specification. If the specification is being met, an early finish is efficiency you are already benefiting from.

Can I get a refund if my cleaner does not stay the contracted hours? If the contract states hours and they were not delivered, a credit is a reasonable thing to request from the contractor. Many clients get better value asking for the shortfall as periodic work instead, such as a carpet clean or washroom descale. Raise it in writing with the shift records attached.

How many square metres can one cleaner cover in an hour? Roughly 300 to 450 m² per hour for general open-plan office areas on a daily specification, and 200 to 300 m² per hour for cellular offices and meeting rooms. Washrooms are counted in minutes per cubicle, not square metres, at 8 to 15 minutes each plus the basin run.

Check the arithmetic before you sign anything

Every Premier quote shows the area, the task list and the time allowed for each, so you can check the arithmetic yourself before you sign. No hidden hours, no numbers that only make sense on a spreadsheet. This is the same transparency behind our full office cleaning Dublin service and our re-clean guarantee.
