The handover is always faintly awkward. You have spent twenty minutes with a cleaner who seems perfectly lovely, agreed a day and a rate, and now there is a key sitting on the kitchen table between you, and one of you has to pick it up. I have done this more times than I can count. I have watched that key disappear into a coat pocket, into a handbag with no discernible bottom, and on one memorable afternoon into a jam jar of assorted keys rattling on a van dashboard, each one presumably belonging to somebody’s home. Not once, in any of those exchanges, did anyone explain what would happen to my key next. And not once did I think to ask.
That was the mistake. The key is the whole thing, when you get down to it. Everything else about hiring a cleaner – the references, the insurance, the good feeling you had about them – collapses into one small piece of metal that opens the place where you sleep. Most of us treat handing it over as a throwaway moment. Yet there is an entire professional discipline devoted to how keys ought to be handled, with a British Standard attached to its name. You will almost never meet a domestic cleaner certified to it, and that is fine. Knowing what it asks for is still the clearest way to see what good looks like, and what to expect from anyone about to hold the key to your front door.
There Is Actually a Standard for This
Keyholding has its own code of practice: BS 7984, currently published as BS 7984-1:2016. It was written for professional security and alarm-response firms – the sort with uniformed, SIA-licensed officers who turn out at three in the morning when your alarm goes off – so no ordinary cleaner is going to be accredited to it, and you should not expect them to be. That is not the point. The point is that the standard distils good key handling down to a few principles, and those principles translate perfectly well to the person cleaning your flat in Maida Vale.
They come down to three things, which happen to sit neatly under the words in this article’s title. A key should be logged, so there is always a record of where it is. It should be stored securely, not carried loose. And the risk that it is lost should be insured, so that the cost of a mistake does not land on you. Hold a cleaner to those three and you have covered almost everything that matters.
Logged: Somebody Should Know Where Your Key Is
The first principle is a record. A professional keyholding operation logs every key in and out, so that at any moment it knows exactly which key it holds, whose property it opens, and who last had it. A one-person cleaning round obviously will not run a control room, but the underlying habit still applies. A cleaner who looks after a dozen homes across Clapham and Balham is holding a dozen keys, and if they cannot tell you how they keep track of which is which, that is worth noticing.
There is a quieter reason this matters, too. A cleaning business holding a list of clients, their addresses and their keys is sitting on a genuinely sensitive set of data – arguably a map of a dozen homes and how to get into them. Under data protection rules they are expected to keep that information secure and limit who can see it. You are within your rights to ask how it is stored, and a thoughtful cleaner will already have considered it rather than keeping everything in the notes app on an unlocked phone.
Stored: A Coded Tag and a Locked Box, Not a Coat Pocket
Here is the single most useful detail in the whole subject, and it costs nothing to check. Your key should never be labelled with your address. Not the full address, not the door number, not “Flat 3, the blue door.” A well-run keyholder tags keys with an anonymous code – a reference that means something only to them – precisely so that if a key is lost or stolen, whoever finds it has no idea which of the eight million doors in London it belongs to. A key with your address on the fob is a housebreaking kit with a map attached. The best keyholders go one step further and keep the list that matches codes to addresses somewhere separate from the keys themselves, so that a single break-in cannot hand a thief both a key and the door it opens.
Beyond the labelling, storage matters. Keys held by a cleaner should live somewhere secure between visits – a locked box or cabinet at their home or premises – rather than jangling loose in a bag that gets left on the top deck of the 137. You are not going to inspect their storage arrangements, and asking to would be a bit much. But the question “where do you keep my key when you’re not here?” is entirely reasonable, and the confidence of the answer tells you plenty.
Insured: Key Cover and Who Pays When It Goes Wrong
Even with the best habits, keys go missing. The question is who carries the cost when they do, and the answer should not be you. This is where key cover comes in – a form of insurance, usually added on to a cleaner’s public liability policy rather than included by default, that pays for changing the locks and cutting new keys if a set is lost or stolen while in their care.
It is worth understanding what that cost can actually be, because it is rarely just a trip to the locksmith. If you live in a mansion block or a converted house with a communal entrance, a lost key can mean replacing a shared locking system, not only your own door – a bill that climbs quickly. A cleaner who holds proper key cover has thought about this. One who looks blank when you mention it has not, and in that case the financial risk of their mistake quietly becomes yours. You can ask to see it listed on their insurance certificate, the same way you would check the cover itself. It is a fair thing to raise before the key changes hands, not after.
The Thing Everyone Forgets: The Alarm Code
A key is only half of the access you hand over. If your home has a burglar alarm, the code is every bit as sensitive as the key itself, and it tends to get passed on even more casually – called out across the hallway on the first morning and never thought about again.
Most modern alarm systems let you set a separate user code alongside the master one. Giving your cleaner their own limited code, rather than the keys to the whole system, means you can see it was used and cancel it in seconds if the arrangement ends. It is a small piece of good practice that costs nothing and closes a gap most people leave wide open.
Or Skip the Physical Key Entirely
The neatest solution to all of this is often to not hand over a key at all. Two options have made that genuinely practical.
The first is a key safe – a coded metal box fixed to an outside wall, holding a key the cleaner retrieves with a PIN. If you go this route, the accreditation matters enormously. Look for one built to the Police Preferred Specification, awarded through Secured by Design, the official UK police security initiative, and attack-tested by the Loss Prevention Certification Board to the standard known as LPS 1175. The cheap, unrated “lock boxes” sold as key safes can be levered open in seconds and are not the same thing at all; the other mark worth recognising is Sold Secure SS314, administered by the Master Locksmiths Association. There is a serious insurance wrinkle here as well: many home insurers will only accept an approved model, and some may reject a theft claim entirely if a burglar got in using a key from a safe, since there is no sign of forced entry. Check your own policy wording before you fit one, site the box somewhere discreet rather than beside the front door where it advertises itself, and change the code from time to time – particularly when a cleaner moves on.
The second option is a smart lock, which lets you issue a time-limited or one-time code to your cleaner and revoke it the moment you like. Better still, most keep a log of every entry, so you can see the door was opened at half past nine on a Tuesday and locked again at eleven – which is, rather pleasingly, exactly the logged-and-controlled access that the professional standard was asking for in the first place, achieved with an app instead of a control room.
What to Ask Before It Leaves Your Hand
None of this needs to turn a friendly arrangement into an interrogation. It comes down to a handful of questions you can ask lightly while the key is still on the table. How will you label it – and please, not with my address? Where do you keep it between visits? What happens, and who pays, if it goes missing? A good cleaner will have answers ready, because they have thought about this side of the job as seriously as the cleaning itself.
The ones who fumble those questions are not necessarily dishonest. More often they simply have not considered that the key is the riskiest thing you own to give away, and that how they treat it is a fair measure of how they will treat everything else you are trusting them with. You are not being difficult by asking. You are just declining to be the person who found out the hard way.
