The Westminster and RBKC line runs through your tenancy
Walk from One Hyde Park down to Beauchamp Place and you cross a council boundary without a single sign telling you. Knightsbridge has been split between two authorities since the parish days of St Margaret and St Martin in the Fields, and the line still matters today. The western slice sits in the City of Westminster; the eastern slice, the Brompton Road side towards Harrods and the museums, sits in the Royal Borough of Kensington and Chelsea. Your postcode might read SW1X, SW3 or SW7. None of that changes what the inventory clerk wants on check-out day, but it changes the parking permit, the refuse day and which council the managing agent quotes at you.
We clean end of tenancy flats across both halves of it. This page is the long version of what we do, who books us, and why a Knightsbridge deposit is not the same animal as one further out.
A quick note on who calls us here. It is rarely the tenant phoning in a panic the night before. More often it is a relocation agent winding down a corporate let, an embassy housing officer closing a diplomatic tenancy, or a managing agent at a Sloane Street firm clearing a lateral flat between two very wealthy occupiers. The brief is usually the same: leave it spotless, leave it fast, do not give the incoming clerk a single line to write up. We have done this in mansion blocks on Lowndes Square, mews houses off Montpelier Walk, and turn-key apartments in the newer towers along Knightsbridge itself.
The lettings churn here is heavier than the quiet streets suggest. SW7 was the single busiest lettings postcode in London last year, with the deal count up on the year before, and the super-prime end of it has been growing rather than shrinking. A lot of that is short corporate and diplomatic tenancies that turn over on a fixed date, and a fixed date means a fixed check-out with no slack in the calendar to redo a clean. The tenants are often not British and often not here at the end: a family from the Gulf, a US executive on a posting, a company that holds the lease and rotates staff through it. The person judging the clean is the agent or the housing officer, working off the inventory, and they have seen a hundred check-outs. The flat either matches the check-in report or it does not, and our job is to make sure it does before they walk in with the camera.
- Check-in inventory
- The signed report made when a tenant moves in. It records the condition and cleanliness of every room, ideally with dated photos. Your clean is judged against this document, not against a vague idea of clean.
- Check-out report
- The inspection at the end of the tenancy, usually by an independent inventory clerk. Cleaning is the single most common reason money gets held back here.
- Deposit protection scheme
- By law the deposit is held in a government-approved scheme. The three are the Deposit Protection Service, the mydeposits scheme and the Tenancy Deposit Scheme. Each runs a free dispute service.
- Fair wear and tear
- Reasonable deterioration from normal use. A clerk must discount it. It is not a licence to skip cleaning, and clerks know the difference.
What an inventory clerk actually checks here
Knightsbridge clerks are fussy. They are paid to be, because the deposits are large and the agents are watching. A clerk working a flat off Hans Place will run a finger along the top of a door frame, lift a rug to check the parquet underneath, open the oven and look at the back wall of it, and photograph the inside of every cupboard. On a lateral apartment that can be forty cupboard interiors. Miss one and it goes in the report.
The standard they hold you to is the check-in inventory. If the flat was professionally cleaned before you moved in, and in this postcode it almost always was, you are expected to hand it back at that level. Not tidy. Cleaned. That is the gap most tenants underestimate, and it is the gap a deduction lives in.
Our team carries a 57-point agent-approved checklist into every job, and we built it around what these clerks write up, not around a generic list of chores. It covers the things that get flats failed here: limescale on chrome in a marble bathroom, oven glass, extractor filters, the inside of the integrated fridge and freezer, skirting and cornice dust, window glass and the runners, mirror surrounds, and the smears that show up on glossed joinery only when the light hits at four in the afternoon. The cleaner stays until the list is signed off. We do not bill by the hour, so nobody is watching a clock instead of the grout.
That checklist is why our first-time pass rate sits at 97%. The other 3% is usually a clerk flagging something we could not reach without work the landlord declined, an oven that needed a separate deep service, or a carpet past the point a maintenance clean can fix. We say so up front rather than promising the impossible.
One more thing clerks check that surprises people. Behind appliances. The dust and grease trap behind a freestanding range, the floor under a dishwasher, the wall behind the washer-dryer in the utility cupboard. In a tight Knightsbridge kitchen those gaps are narrow and they are exactly where a lazy clean gets caught.
It is worth saying what the clerk is comparing against, because tenants get this wrong all the time. The check-in report is the baseline. If the inventory says the flat was professionally cleaned to a high standard at the start, with photos of a spotless oven and clear glass, then “I tidied up and wiped the surfaces” is not a defence. The clerk is not asking whether you cleaned. The clerk is asking whether the flat now matches the photos taken on day one. In a postcode where almost every flat is professionally cleaned before a new tenant moves in, the bar is high by default, and a tenant who cleans to a normal domestic standard still lands short of it.
There is a second document people forget: the tenancy agreement itself. Many Knightsbridge leases, especially corporate and embassy ones, have an explicit professional-cleaning clause, sometimes requiring a receipted clean. Where that clause exists, a clerk looks for evidence the clean was done properly, not just that the flat looks alright on the day. We leave a dated invoice precisely so that box is ticked.
The bathrooms are where most Knightsbridge flats are won or lost. These are not plastic trays and acrylic baths. They are marble, limestone, polished chrome, frameless glass, sometimes a wet room with a single drain. Hard central London water leaves a film on chrome and a haze on glass that a quick wipe spreads rather than removes, and a clerk runs the screen at eye level against the light where that haze shows immediately. Getting the glass properly clear, and the chrome back to a mirror without scratching a soft finish, is skilled work, and it is the thing we get asked to re-check least often because we spend the time on it that a rushed clean does not.
Kitchens are the other battleground. Integrated appliances mean the oven, the combination microwave, the dishwasher, the fridge and freezer and often a wine fridge are all built in behind matching doors, and every one of them has an interior the clerk will open. The oven is the classic. Door glass, the back wall, the roof of the cavity, the runners, the racks. An oven that has cooked for a family for two years is not a wipe-down job, and on a heavy range it is usually a separate deep service rather than part of the standard clean, which we will tell you when we quote rather than discovering it on the day.
The maths on a six-week Knightsbridge deposit
Here is where Knightsbridge differs from almost everywhere else we work. The deposit cap is set by the Tenant Fees Act 2019. For most of the country the cap is five weeks’ rent, because most tenancies have an annual rent under fifty thousand pounds. Knightsbridge tenancies usually do not. Schedule 1 of the Act sets a higher cap of six weeks’ rent where the annual rent is fifty thousand pounds or more, and in SW1X and SW7 that threshold is cleared on a one-bedroom flat, never mind a lateral apartment.
So the sum is blunt. Six weeks’ rent on a flat letting at two thousand pounds a week is a five-figure deposit. A clerk who writes up a flat as needing a full professional clean before re-letting can support a cleaning deduction running into hundreds, sometimes more on a large apartment, and on these sums an agent will pursue it because the incoming tenant expects the same standard the outgoing one was given.
Six weeks’ rent on a flat letting at two thousand pounds a week is a five-figure deposit.
The deposit is not sitting with the landlord. By law it goes into a government-approved scheme, and the landlord or agent has to protect it within thirty days of taking it and give you the prescribed information. The official rules are on GOV.UK. If there is a row about cleaning at the end, you do not have to sue anyone. Each scheme runs a free dispute service, an adjudicator looks at the evidence both sides send in, and they decide how the money is split. Citizens Advice sets out the route plainly, including that you usually need to raise the claim within three months of moving out.
The deposit cap rules did not change when the law was updated. The Renters’ Rights Act 2025 amended the Tenant Fees Act and came into force on 1 May 2026, but the five-week and six-week caps still stand. What changed is the enforcement around landlords, not the maths on your deposit.
People sometimes assume a bigger deposit means the landlord can hold more back for cleaning. It does not work like that. The size of the deposit is the ceiling on what can be taken, not the amount that will be. A cleaning deduction has to reflect a real, evidenced cost of returning the flat to its check-in condition, minus fair wear and tear. On a five-figure deposit the cleaning line is rarely the largest figure on the schedule of deductions, but it is almost always there, and it is the one a tenant can wipe out completely with a single professional clean and the receipt to prove it. You are not buying a clean flat. You are buying the removal of a line item from a deduction schedule.
There is a timing trap worth flagging too. The dispute clock is short. You generally have to raise a deposit claim with the scheme within three months of moving out, and the adjudicator wants the check-out evidence to be close in time to the tenancy ending, because the longer the gap between hand-back and inspection, the more room there is to argue something happened after you left. On a Knightsbridge changeover the incoming tenant often moves in within days, so the inspection is usually quick, which works in your favour only if the flat was handed back clean. If it was not, that same speed works against you.
One point specific to high-value lets. Where the tenancy is held by a company rather than an individual, it may sit outside the assured shorthold regime and the statutory deposit-protection rules can apply differently, so the route to challenge a deduction can differ on a corporate let. That is a question for the agent and the lease. What does not differ is the evidence that wins a cleaning argument: the inventory, the photos, and a dated professional cleaning invoice. We supply the last of those as standard.
Getting cleaners to a flat off Brompton Road
The parking around here is the worst part of the job, and I will say that plainly because anyone who has worked Knightsbridge knows it. The streets off Brompton Road sit in tight controlled parking zones, and the boundary means a permit that works on the Westminster side is no use a hundred metres east in the Royal Borough. We plan a van around that. For a lot of jobs the team comes in light by Knightsbridge station on the Piccadilly line, which sits more or less under Harrods, rather than fighting for a kerb that does not exist.
Then there is Harrods itself. The delivery and coach traffic around the Brompton Road and Basil Street side is constant, and a Saturday near the store is its own kind of slow. We do not book a tight check-out slot for a Saturday lunchtime on Hans Crescent if we can help it. Mews jobs off Montpelier Walk or behind Rutland Gate are easier for access but the lanes are narrow and often half-blocked by a resident’s car or a building skip, so we send a smaller team and carry kit in.
If the flat is in a mansion block, the porter usually wants notice and a service-lift booking. We are used to that. We will call the front desk ourselves, give them the team’s names, and work around the building’s rules on which lift, which entrance and what hours cleaning contractors are allowed in. Concierge buildings like the newer towers along Knightsbridge are stricter still, and a corporate or embassy tenancy will often have the relocation agent coordinating that part. We slot into whatever process is already running.
One small grumble while I am here. Loading near the museums end, towards Exhibition Road and Ennismore Gardens, gets clogged by tour coaches on weekday mornings, so an early start there is better than a mid-morning one. We schedule with that in mind because a team stuck on Brompton Road is a team not cleaning your flat.
The serviced and short-let clusters have their own quirk. Cheval Place and Lancelot Place behind the Brompton Road have a lot of short tenancies and serviced apartments, which means quicker turnover and tighter windows, sometimes a same-day in and out where the outgoing tenant leaves at ten and the incoming one arrives mid-afternoon and the entire clean has to happen, and pass, in between. That is fine if the booking and the access are sorted in advance. It is a disaster if nobody told the building we were coming, which is why we ask about the porter and the access rules when you book and not when the team is standing on the pavement.
If you drive yourself, a quick aside that catches people out at the end of a tenancy: this is all inside the Congestion Charge zone and the wider low-emission zone, so a removal van or your own car attracts the daily charges on top of the parking headache. It is one more reason most of our Knightsbridge work runs off the tube and a tightly planned drop rather than a van sat on a meter all afternoon. It keeps your fixed price fixed, because we are not passing a parking and charging bill back to you in a padded quote.
Mansion blocks, mews and new-build, room by room
Knightsbridge housing is not one thing, and the clean changes with the building. The stock runs from grand white stucco terraces and red-brick Victorian mansion blocks through narrow mews houses, many now re-linked to the main house for parking or staff, to lateral apartments and the ultra-prime new towers. We clean all of it. Each type has its own traps on a check-out.
Period mansion blocks. Think Lowndes Square, Hans Place, the blocks around Rutland Gate. High ceilings mean high cornicing and tall sash windows, and clerks check the tops of both. Original parquet and stone floors need the right method, not a wet mop that lifts a board or dulls marble. Cast-iron radiators collect dust in the fins. Old kitchens often have a separate utility or maid’s cupboard that gets forgotten on a self-clean and never gets forgotten by a clerk.
Mews houses. Small footprint, two or three floors, a steep staircase and often a garage at ground level. The clean is quick on volume but the stairs, the galley kitchen and the single tight bathroom take the time. A re-linked mews used as staff accommodation gets heavier wear than the main house and the clerk knows to look harder there.
Lateral and new-build apartments. One Hyde Park, the towers along Knightsbridge, the larger schemes near the barracks with the tall Spence tower behind them. Glass, polished stone, integrated everything, and a lot of it. The work here is volume and finish: every appliance interior, the gloss joinery that shows every smear, floor-to-ceiling glazing, the wet rooms with their chrome and screens. Turn-key flats in branded buildings are handed back to a hotel-grade standard because the incoming tenant is paying for exactly that, and the agent will hold you to it. A lateral flat can have three or four bathrooms and a kitchen the size of a small flat elsewhere, so the clean is a day’s work for a proper team, not an afternoon for one person with a mop.
The new towers add a process layer on top of the cleaning. Concierge buildings control who comes in and when: a contractor sign-in, a designated service lift, set hours, sometimes a requirement to dust-sheet the lift and corridors. None of that is a problem for us, but it has to be booked, and on a corporate or embassy tenancy the relocation agent usually holds that building relationship. We confirm it before the day, because a team turned away at a concierge desk for want of a booking is the worst possible start to a tight changeover.
A word on the squares, because they come up. Montpelier Square, Ennismore Gardens, Lowndes Square, Rutland Gate, Cadogan Square, Lennox Gardens, Wilton Place near Belgravia: the flats in them are mostly conversions inside listed or conservation-area buildings, so original features stay original. You cannot strip a period cornice or take a wire brush to old ironwork. The skill is getting decades of London dust off delicate plaster and timber without marking it, and a clerk in one of these flats checks exactly those surfaces because that is where a cheap clean cuts the corner.
Knightsbridge housing is not one thing, and the clean changes with the building.
Whichever it is, the job is the same shape. The cleaner brings the supplies and the equipment, so the flat does not need anything beyond electricity and running hot water. Carpets, rugs and any upholstery get hoovered. Appliances are cleaned inside and out. Mirrors, glazing, sills and runners are done. Skirting, cornice and joinery are dusted and wiped. The kitchen is degreased, the cupboards and drawers cleaned inside and out, the sink and taps descaled. Bathrooms get the full treatment: limescale off the chrome, glass screens and shower doors, tiles and grout, toilet, bath, basin. Cobwebs gone. We ask two things of you before we arrive: take all personal belongings out, and defrost the fridge-freezer so we can clean it properly rather than around a block of ice.
If you want the wider clear-out handled too, our removals team can run alongside the cleaners, and our deep cleaning and domestic cleaning services cover the jobs that are not strictly end of tenancy. A lot of Knightsbridge clients book the move and the clean together because coordinating two firms across a porter’s access window is its own headache.
When the agent or relocation firm challenges the clean
Sometimes a clerk or an agent disagrees with the result. It is rare for us, but it happens, and on Knightsbridge deposits it is worth handling properly because the sums are large. So we put a real guarantee behind the work: our 48-hour re-clean guarantee. If the inventory clerk or the letting agent challenges the cleaning within 48 hours of us finishing, we come back and re-clean the flagged items free. No argument, no invoice. We would rather send a cleaner back for an afternoon than have you lose a chunk of a five-figure deposit over an oven door.
That offer only works because we are in these buildings constantly and we know what the local clerks expect. We are on the books of 300+ letting agents and have helped tenants recover £1.2m in deposits that would otherwise have gone on cleaning deductions. That figure is the whole point of the service. The clean is not the product. Keeping your money is.
If a deduction is still pushed despite a proper clean, the deposit scheme’s free dispute process decides it, and evidence wins there. The independent adjudicator weighs the tenancy agreement, the signed check-in and check-out reports, dated photos and any cleaning receipts. Shelter explains how to challenge unfair deductions, and the burden of proof sits initially with the landlord to show a real loss. A professional clean with a dated invoice from us is exactly the kind of evidence that tips a cleaning dispute, which is why we always leave you with paperwork, not just a clean flat. A published mydeposits dispute case shows the pattern: where the tenant could prove the flat was handed back properly cleaned, the cleaning claim was cut right down.
Booking, add-ons and the wider job
Booking is a phone call. Tell us the flat: how many rooms, how many bathrooms, the building type, and whether there is a porter or concierge we need to clear access with. We give you a fixed quote on the size of the place, not an hourly rate, so the price does not move because the team had to stay an extra hour on the grout. We work weekends at the same price as weekdays, which suits the tight changeover windows that relocation and managing agents work to. Our prices are on the prices page and you can reach the team through contact us.
Some flats need add-ons, and a clerk will say so if the standard clean cannot fix something. The common ones here:
- Carpet cleaning by hot water extraction, for wool carpets and runners in period flats that a hoover will not bring back.
- Hot water extraction for sofas and chairs too, our upholstery cleaning, where soft furnishings are part of a furnished let and the clerk has logged them.
- Oven cleaning as a separate deep service, the racks and removable parts taken out and cleaned apart from the cavity. Knightsbridge kitchens often have a range or double oven, and a heavy one needs this rather than a wipe.
- Exterior window cleaning with water-fed poles and purified water, where the tenancy or the inventory requires the outside of the glass done as well as the inside.
- Hard floor cleaning for stone, marble and parquet, which need the correct method on a check-out, not a wet mop.
If you are moving within the area or out of it, it is worth looking at the rest of our coverage rather than treating Knightsbridge as an island. We clean across the wider patch on both sides of the borough line. Common neighbours people also ask about are Belgravia, just east past Lowndes Square, Brompton down the road towards the museums, South Kensington, Sloane Square at the Chelsea end of Sloane Street, Mayfair over Hyde Park Corner, Pimlico and Hyde Park on the Westminster side, and Gloucester Road and Cromwell Road heading west. The full picture, including how an end of tenancy clean differs from a deep clean, is on our end of tenancy cleaning hub, and there is more on the wider Kensington High Street and Knights Hill rounds if your move is taking you further out.
Knightsbridge end of tenancy cleaning, common questions
Does the Westminster and Kensington and Chelsea boundary change my end of tenancy clean?
Not the clean itself. The inventory standard is set by your check-in report, not by the council. The boundary does affect the parking permit, the refuse day and which council the managing agent deals with, so we plan van access and timing around which side of Knightsbridge the flat sits on, but the cleaning specification is the same on both sides.
Why is my deposit six weeks’ rent and not five?
The Tenant Fees Act 2019 caps deposits at five weeks’ rent where the annual rent is under fifty thousand pounds, and six weeks’ rent where it is fifty thousand pounds or more. Most Knightsbridge tenancies clear that threshold, so the six-week cap applies. It means the deposit at stake is large, which is exactly why a clean that passes first time matters here.
What does your 57-point checklist cover?
It is the agent-approved list our cleaners work through on site, built around what local inventory clerks write up. It covers appliance interiors, oven glass and extractor filters, limescale on chrome, glazing and runners, skirting and cornice, joinery smears, cupboard and drawer interiors, and the bathroom detail clerks check first. The team stays until every point is signed off.
What happens if the inventory clerk or agent is not happy with the cleaning?
We re-clean the flagged items free if the clerk or agent challenges the work within 48 hours of us finishing. There is no extra charge and no argument about it. If a deduction is still pushed afterwards, your deposit scheme runs a free dispute service where an adjudicator decides on the evidence, and the dated invoice we leave you is the kind of proof that wins a cleaning dispute.
Do you clean lateral apartments and flats in concierge buildings like One Hyde Park?
Yes. We clean lateral apartments, period mansion-block flats, mews houses and new-build towers across SW1X, SW3 and SW7. For concierge and porter buildings we book the service lift and clear contractor access with the front desk ourselves, or coordinate with the relocation agent if it is a corporate or embassy tenancy.
How do you price an end of tenancy clean in Knightsbridge?
By the size of the property, not by the hour, after a free quote over the phone. We need the number of rooms and bathrooms and the building type. The team stays as long as the job takes to pass, with no hourly meter, and weekend visits cost the same as weekday ones.
What do you need from me before the clean?
Two things. Remove all personal belongings, and defrost the fridge-freezer so it can be cleaned properly. The flat also needs electricity and running hot water. We bring all cleaning supplies and equipment, so nothing else is needed from you.
Can you handle the move and the clean together?
Yes. Our removals team can run alongside the cleaners, and we also offer deep and domestic cleaning for jobs outside a standard end of tenancy. Booking both with one firm avoids coordinating two contractors through a single porter access window, which is the part most people in Knightsbridge find awkward.
