The Cleaner Has Keys to the Building at 2am. Does Your Vetting Reflect That?

A daytime office contract has a client on site, or at least nearby, most of the time a cleaner is working. Someone notices if a room’s been missed, someone’s around if a door won’t lock, someone would notice if a stranger walked in. Night cleaning and security-cleared sites remove all of that. A cleaner arrives at 2am with a set of keys, an alarm code, and nobody else in the building, and whatever happens between then and the alarm being reset in the morning is, functionally, on trust alone. Most cleaning companies vet staff the same way regardless of whether the shift is a 6pm office visit or an unsupervised overnight run of a site holding sensitive material, and that’s a gap worth closing before a client asks the question you can’t answer.

Vetting depth needs to match the level of unsupervised access

A basic DBS check is a starting point, not a finishing line, once a shift means someone holds keys and alarm codes with no one else present. The same standard now expected around DBS status and right-to-work documentation on commercial contracts applies with even more weight on a night contract, because there’s no supervisor on site to notice if something’s off. Length of tenure, reference checks that were actually followed up rather than collected and filed, and clarity on who’s been individually cleared for which site all matter more here than on a standard daytime contract.

Access logging isn’t bureaucracy, it’s the only record that exists

On a daytime site, if something goes missing or a door’s found unlocked, there’s usually a witness or at least a rough idea of who was around. On a night contract, the access log is often the only evidence of who was in the building and when. Alarm activation times, key sign-out records, and building entry logs matter far more here than on a contract where someone else is around to fill in the gaps.

Proof of presence matters more when nobody’s there to see it

The same argument covered in the £2,000 vase and the client who swears you never even showed up applies with sharper edges on a night contract. Without a timestamped, site-verified record of the visit, an unsupervised shift is entirely your word against a client’s, and on a site handling security clearance or sensitive material, that’s not a dispute you want to be having from a position of no evidence at all.

None of this needs to slow a company down. It needs a record that exists automatically rather than being reconstructed after the fact, because the moment a client asks who was in their building at 2am last Tuesday, “I’ll check with the team” is a much weaker answer than a log that already has it.
