How to Change Cleaning Contractors Without a Gap

Almost every facilities manager who has changed cleaning contractors has a story about the first fortnight. Bins missed, alarm codes that did not work, nobody knowing which door the bins go out of, and a run of complaints that makes the whole decision look like a mistake.

Very little of that is caused by the new contractor being worse. It is caused by a site's worth of knowledge living in the heads of the outgoing cleaners and nobody writing it down before they left.

Here is the sequence that avoids it.

Read the termination clause before you do anything else

Start at the end of the current agreement, not the beginning of the new one.

Check:

• The notice period, and whether notice must be in writing to a specific address
• Whether the term auto-renews, and the date by which notice must land to stop it
• Any minimum term remaining, and what breaking it costs
• What happens to equipment on site — machines, dispensers, caddies. Some are contractor-owned and leave with them
• Whether consumables stock on site belongs to you or to them
• Any obligation to make good, or to return keys and access devices formally

The auto-renew date is the one that catches people. Miss it by a week and the decision is made for another twelve months.

Do not give notice until the replacement is signed

Obvious, and routinely ignored because the decision to leave feels urgent.

The moment notice is given, the outgoing contractor's incentive changes. Standards usually slip, their best staff get moved to sites they are keeping, and you lose the leverage to have anything fixed. If the new contract then takes three weeks to finalise, you spend those weeks with a service that has already checked out.

Sign first. Then give notice with a start date that lines up.

Capture the site knowledge while the outgoing team is still there

This is the step that actually determines how the first fortnight goes, and it is the one almost nobody does.

Every site has operational detail that is not in the scope document:

• Which door is used for access, and which key or fob opens what
• Alarm zones, codes, and who to call when it trips at 10pm
• Where the cleaner's store is, and what is in it
• Bin collection days, where bins are presented, and where they are returned to
• Which floors have restricted areas — server rooms, records, executive offices — and what the rule is
• Lift access after hours, and whether a swipe is needed
• The one meeting room that always needs resetting, and the desk nobody is allowed to touch
• Loading dock booking, if there is one

Write this down as a site file before the handover, not during it. If you can, get the outgoing supervisor to walk the incoming one through the building. It is a reasonable thing to ask for in the final month and most contractors will agree to it.

Overlap the last week

The cleanest transitions have one week where both contractors are engaged — the outgoing one finishing the term, the incoming one attending at least once to walk the site with their own supervisor and set up.

Use that week to:

• Confirm keys, fobs and codes work, tested by the people who will actually use them
• Check the store is stocked, and agree who is buying the first month of consumables
• Confirm the alarm monitoring list has the new names on it
• Have the new team meet whoever is on site late — security, building management
• Agree the first-visit checklist

Paying a week of overlap is far cheaper than a fortnight of complaints. If the budget will not carry it, at minimum insist on an access test before the first live night.

Time the switch away from month end and holidays

Do not start a new contractor on the first business day after a long weekend, in the last week of a quarter, or the night before an audit or an inspection.

The best start date is a quiet mid-month week when the building is normally occupied, so problems surface immediately and get fixed while everyone is paying attention. A start date during a shutdown means the first real test happens weeks later, when everybody has stopped watching.

Set a review at four weeks and mean it

The new contractor will get things wrong in the first month. That is expected and it is fixable. What matters is whether there is a scheduled point at which it gets addressed rather than accumulating into resentment.

Book a review for four weeks in, with:

• The complaint log, if there is one
• The per-visit records for the month
• A walk of the site with the account manager
• A written list of what changes, and by when

Do the same at three months. After that, quarterly is usually enough.

What to put in the new contract while you have the chance

Changing contractors is the one moment you have full leverage. Use it to fix whatever was wrong with the last arrangement:

• A scope written task by task with a frequency against each, not a paragraph of prose
• Periodic work named and scheduled, with dates, not left as variations
• A per-visit record you can actually see
• A named account contact and a response time for issues
• Consumables treated explicitly — included, at cost, or excluded
• Notice period and renewal date stated plainly, so the next review is on your terms
• Site induction required for every attending cleaner, including relief staff

The clause worth arguing hardest for is the last one. Continuity of staff is what makes a cleaning contract work, and a contractor who cannot commit to inducting whoever they send is telling you the roster is going to churn.

The part nobody warns you about

For about two weeks the new contractor will clean your building to the scope, and the scope is not identical to what the previous team did out of habit. Things that were being done for free will stop, and someone will notice.

That is not a failure. It is the difference between a documented service and an undocumented one becoming visible. Deal with it by deciding which of those habits you actually want, and adding them to the scope properly so they survive the next change of contractor too.

We take over sites regularly and this is how we run it — a site file built before the first shift, an overlap walk where the outgoing team allows it, and a four-week review in the calendar from day one. If you are weighing up a change, we are happy to walk the building and tell you what the handover would involve, whether or not you end up using us.
