The keys go back on a Friday and the argument starts the following Tuesday. I’ve cleaned enough offices and units on their way out to know the pattern by heart: a tenant thinks they’ve handed back a clean building, the landlord’s surveyor thinks otherwise, and a schedule of dilapidations lands weeks later with a cleaning bill nobody saw coming. Most of that fight is avoidable. It comes down to what got cleaned and whether anyone thought to photograph it. This is the commercial end-of-tenancy clean, and it works nothing like the domestic version.
What does “end of tenancy” actually mean in a commercial lease?
In a domestic let, end of tenancy cleaning is a fairly settled thing – a checklist and a deposit scheme to referee any dispute. Commercial is a different animal. Most business premises in London are let on full repairing and insuring terms, which means the tenant carries the cost of keeping the place in order and handing it back that way. The lease contains a yield-up clause, and it usually says the tenant must return the premises clean and clear of their belongings at the end of the term. “Clean” there means a good deal more than a hoover round on the last afternoon. A surveyor measures it against what the building ought to look like, and any shortfall turns into money.
There’s no deposit scheme to protect you either. The landlord’s route to recovering cleaning and repair costs is a schedule of dilapidations, served by their surveyor, listing every alleged breach with a price beside it. That schedule is an opening position, not a bill you’re obliged to settle in full – but tenants who don’t know that pay it in full nine times out of ten.
Why a schedule of condition changes everything
If one document decides how the end plays out, it’s the one taken at the start. A schedule of condition is a dated, photographed record of the premises on day one, agreed and attached to the lease. Where one exists, the tenant only has to hand the place back in that state – dust and wear that were there at the outset aren’t yours to fix. Where one doesn’t, you’re arguing from memory against a surveyor with a camera, and memory loses. I’ve seen a tenant save five figures on a Wandsworth claim purely because someone had the sense to photograph the grubby carpet tiles before the desks went in.
What does a proper commercial end-of-lease clean actually involve?
Scale is the first shock. A warehouse isn’t cleaned the way a flat is, and neither is a fifteen-thousand-square-foot office floor, and the things that generate dilapidations claims are rarely the things a tenant’s own staff think to touch. The visible floor gets done. The trouble hides above head height and under the furniture.
Kitchens and tea-points are where I find the worst of it. Years of splashback grease behind a microwave nobody ever moved, a fridge seal gone black at the folds. Washrooms tell the same story – limescale furring the taps and hard-water staining down the urinals. The extractor grilles, up where you’d need a step-ladder, sit packed solid with dust. None of it shows until someone runs a finger along it, and a surveyor runs a finger along everything.
Then the floors. Carpet tiles in a long-occupied office are often past cleaning and into replacing, and there’s a real argument to be had over whether that’s fair wear or a genuine breach. Vinyl needs stripping and resealing, not mopping. And in the industrial units, the floor is the whole game.
I cleaned a light-industrial unit off Coronation Road in Park Royal last year where the outgoing tenant had run a small fabrication business for a decade. The concrete was a map of oil stains, forklift tyre marks and the pale shadows where racking had stood bolted down since before they arrived. They’d assumed a jet-wash would sort it. It didn’t – oil that’s soaked into unsealed concrete for ten years doesn’t lift with water and good intentions. We degreased it in stages across three days, and even then some of the deep staining stayed. The lesson the tenant took away, too late to spare them, was that the floor should have been sealed the week they moved in.
The outside counts too, more than tenants expect. Loading bays and yards get inspected. So does the external glazing, and the ghost of a fascia sign left behind as a rectangle of clean brick and a row of drilled holes when the tenant’s board finally comes down. A clean that stops at the front door leaves a surveyor plenty to write up.
The bits every tenant forgets
High-level cleaning is the great blind spot – the tops of partitions and the ductwork nobody’s looked at since the fit-out, furred grey with dust. Floor boxes are the other one: those recessed power-and-data points sink into the carpet, fill with dust and biscuit crumbs, and get missed completely because the desks sat on top of them for years. Then the glass, which shows every fingerprint – the manifestation strips on partitions, the smears at door-handle height. This is the layer that separates a clean a surveyor signs off from one they mark up, and nine times out of ten it’s the layer a general office clean skips.
Where do outgoing tenants get caught out?
The single biggest mistake is treating the clean as the last job instead of the first. Tenants spend the final week shifting furniture and cancelling the broadband, then send two people round with a vacuum on the last morning and call it done. By the time the schedule arrives, the building’s been relet or stripped and there’s no way left to prove what state you handed it back in.
I’ve watched this next part happen too many times to call it coincidence. Managing agents put cleaning items on dilapidations schedules that they know a tenant’s own photographs would knock straight off – the “professional deep clean throughout” line, priced at a figure designed to make you flinch. They do it because most tenants pay rather than argue. I think that’s closer to a shakedown than a claim, and the one thing that reliably stops it is evidence the tenant took the trouble to gather on the way out.
A receipt proves you paid, not that you cleaned
Tenants wave invoices at managing agents as though a receipt from a cleaning firm settles the matter. It doesn’t. A receipt proves money changed hands. It says nothing about the state of the third-floor kitchen the day you left. What holds up is a dated set of photographs – wide shots and close-ups of every problem area, taken the morning the keys go back. Nine times out of ten the tenant who brings photographs to the negotiation pays a fraction of what the tenant with a receipt pays. Do the clean, then prove it. The proving is half the job.
What should landlords and managing agents actually ask for?
Landlords and their agents have a fair interest here. A building handed back filthy is genuinely harder to relet, and a tenant who’s wrecked a tea-point should put it right. The trouble starts when the clean becomes a way to hand the landlord a better building than the one they let out.
That’s betterment, and the law won’t have it. A landlord can require the premises back in the condition they were let in, not upgraded at the departing tenant’s expense. If the carpet was mid-life and tired when the tenant took the keys, they don’t owe you a new one. Section 18 of the Landlord and Tenant Act 1927 caps what a landlord can actually recover at the drop in the building’s value caused by the breach – so if you’re refurbishing the whole floor anyway, the cleaning you’re claiming for may be worth nothing once the sums are done. That’s the part agents tend to skate over: the headline figure on a schedule and the figure a landlord can actually recover after Section 18 are often two very different numbers.
Good agents know this and scope realistically. The smart instruction to a cleaning contractor is plain: get the building to relettable standard and document it. A defensible, photographed clean is worth more at settlement than an inflated one that falls over the moment it’s challenged.
The betterment trap
I get asked more often than you’d think to quote for a clean that’s really a refurbishment wearing a disguise – strip the lot out and bill the departing tenant for a building that looks new. I don’t play that game, and the agents worth working with don’t ask me to. A contractor who’ll dress up betterment as dilapidations is a contractor who’ll hand over a document that comes apart the second the tenant instructs their own surveyor. The credible clean is the one scoped to the lease, not to the landlord’s wish-list.
Can you get through a commercial move-out without the dilapidations fight?
Mostly, yes – and the tenants and agents who manage it tend to do the same two things. They agree the standard up front, and they inspect together.
The walk-round that settles it before it starts
The clean that never turns into a dispute is the one where both sides walked the building together before the keys changed hands. The landlord’s agent and the outgoing tenant in the same rooms on the same afternoon – ideally with the contractor who did the work standing alongside them – agreeing what’s clean and what still needs attention while there’s time to fix it. Half an hour of people sorting it out in person, in the actual tea-point, beats three months of surveyors’ letters. Book the clean early enough that a week sits between finishing and handing back, so there’s room to put right anything the walk-round throws up. The tenants who leave it to the last morning are the ones I hear about later, still arguing the toss six months after they moved out.
