We work with over 300 letting agents
On a Sloane Gardens hand-back the inventory clerk goes for the bath waterline before anything else: that chalk haze along an original enamel rim is the single most reliable deduction in SW1W, and the supermarket bath cleaner the last tenant used never touched it.
So end-of-tenancy cleaning around Sloane Square is built to satisfy the person writing the check-out report, room by room, against a 57-point agent-approved checklist, at a fixed price by bedroom count, with a 48-hour re-clean guarantee measured against the report itself. Ring 0333 555 2076 for a price in about three minutes.
Last updated June 2026. We cover the Sloane Square postcodes: SW1W as the core, plus the Chelsea slices of SW3 around Cadogan Square and the fringe of SW1X. This page sits inside the borough directory at End of Tenancy Cleaning Kensington & Chelsea.
The check-in report you are quietly measured against
End of tenancy cleaning
from £156
For a studio, fixed by property size, agreed before we start.
Start with the document, because the whole hand-back turns on it.
When you moved into a flat off Sloane Square, a clerk walked it and wrote a report describing every surface, almost always with photos, and almost always with the words “new” or “as new” against the kitchen and the bathroom. Those words were true that day, because the flat had just had a professional clean.
At check-out a clerk walks it again and goes line by line.
Anything materially worse than the check-in entry, past fair wear and tear, can be charged against your deposit.
You are being held to a professional standard, which is exactly why a mop and a spare Saturday rarely gets a tenant there.
A 1-bed mansion flat on Sloane Gardens letting at well over £1,000 a week is above the £50,000-a-year line, where the deposit cap rises to six weeks’ rent, so a clerk does not need to find much to take a real number out of it.
Why is the clerk so exacting here? The deposit is large and the agent is on the hook for protecting it, so the inspection is adversarial. The clerk is paid to find faults, not to wave you through. That is not unfair. It just means you turn up with evidence rather than optimism.
Two things sit behind all of this in law, pulling in opposite directions.
A landlord here cannot make a professional clean a contractual condition, so nobody can force you to book us.
Damp and mould
These are a landlord obligation, not a tenant cleaning failure. Where we find genuine damp behind a wardrobe or in a cold bathroom corner, we photograph it and note it, so the charge lands where it belongs instead of on your deposit.
The first round was the cheap one to win.
Two estates meet at the square, and the flats change with them
Sloane Square is the seam between the two great London estates, and the flats change as you cross it.
West and south: the Cadogan Estate
Walk into Chelsea and you are on Cadogan land, roughly 93 acres of it.
North-east: Grosvenor land
Cross toward Belgravia and Pimlico and you move onto Grosvenor land and, past the eastern edge, into the City of Westminster.
The council
Most of the residential streets this page works sit in the Royal Borough of Kensington and Chelsea: Sloane Gardens, Cliveden Place, Cadogan Place, Lower Sloane Street and Holbein Place.
Licensing
RBKC runs no selective licensing across these frontages, so most landlords here let without a council licence. That puts the whole weight of enforcement on the deposit scheme and makes an unarguable clean at hand-back matter more.
The stock is grand and it is not one thing. Three bands, and the clean changes across them.
The stucco mansion blocks and Cadogan terraces
The classic Sloane Square flat is a tall stucco-fronted mansion block or a converted terrace house with porter, lift, eleven or twelve-foot ceilings, original cornicing, ceiling roses and deep skirtings.
Sloane Gardens runs to generous lateral flats with ornate entrance halls, encaustic tile floors and mahogany staircase joinery.
Cliveden Place and Lower Sloane Street give you the Cadogan Estate terrace stock, much of it carved into flats.
The inventory names the cornice, the picture rail and the architrave individually, so the clean has to match them individually, and nothing aggressive goes near original paint or plaster.
The red-brick Pont Street Dutch blocks
Push toward Cadogan Square and the fronts turn red. These are the 1880s and 1890s gabled mansion blocks in moulded red brick and terracotta, the style Chelsea coined Pont Street Dutch, with big mullioned windows and Flemish gables up top.
Inside they are lateral flats with the same high ceilings and plaster detail, often with a kitchen and bathrooms refitted in the last twenty years inside the older shell. The clean has to cope with both eras in one flat:
granite and integrated Miele above
a cast-iron column radiator and an original bath below
The diplomatic and corporate lets
A lot of these tenancies are international: corporate relocations, diplomatic lets, high-value short professional tenancies managed by prime agents. The check-out is handled by one of the named local offices, and we work with all of them:
John D Wood & Co keep a Sloane Square office
Russell Simpson have run Chelsea lettings since 1979
Foxtons and Hamptons both have Sloane Square branches
On Cadogan Estate stock the hand-back can also go through the estate’s own surveyor alongside the agency clerk, which means two sets of eyes, not one.
Across the boundary the same patterns run into Belgravia and down the high street into Chelsea, with the boutiques and the Royal Court Theatre on the King’s Road end.
Not sure which side of the line your flat sits on? The square straddles a boundary and people guess wrong. Ring 0333 555 2076 with the postcode and we will tell you in about ten seconds.
What 1 May 2026 changed for an SW1W move-out
The Renters’ Rights Act 2025 went live on 1 May 2026. It changed the timing of a hand-back and nothing about the cleaning.
Section 21
No-fault evictions are gone.
Existing tenancies
Every existing assured shorthold tenancy in England has converted to a periodic tenancy.
Notice
A tenant can now give two months’ notice at any point in the year instead of waiting for a fixed term to end.
Here is the part people get wrong. The cleaning side of a move-out did not change at all:
the Tenant Fees Act still applies
the check-in benchmark still applies
the deposit maths is exactly what it was the week before
What changed is timing, and timing is what bites around Sloane Square. This was already a high-churn corner of London, full of one-year corporate lets and short professional tenancies.
A job our cleaners finished in Kensington and Chelsea.
Let tenants leave on a rolling two months instead of a fixed end date and the hand-backs get more frequent and far less predictable, so the month-end pile-up that already clogs the prime postcodes is not about to ease.
The practical takeaway is dull and it pays for itself: book the clean earlier than you used to, because the slot you want will be gone if you wait until the week of the move.
The 57 things we work, room by room
Every Sloane Square booking runs to a 57-point agent-approved checklist, built over a decade of local hand-backs and tuned to what these clerks flag. The full list comes with the job. Here is the shape of it.
From one of our jobs in Kensington and Chelsea.
The kitchen, where a lot of the money is
The oven, added to the clean from £31, is hand-cleaned, not wiped. The racks come out and soak while the interior, fan, element and seals are scrubbed, and the brown film between the panes is cleared where the door design allows.
On a Cadogan Estate flat the kitchen is usually a refit inside a period shell: granite worktops, integrated AEG or Miele appliances, often a waste-disposal unit at the sink. That disposal is the under-noticed item, because it is where the smell lives that the clerk picks up, so a descaler goes through it and the rim gets wiped.
Then the rest of the room:
Hob rings and burners off, control knobs washed
Extractor hood degreased inside and out, with the filter soaked or swapped
Every cupboard, inside and out
Fridge and freezer done once defrosted
Appliances pulled out so the gaps behind and under get cleaned, then put back
The washing machine drum, the detergent drawer scrubbed, and the door seal, which is the first thing the clerk opens
Dishwasher filter, seals and spray arms
Sink, taps and plughole descaled
Tiles and grout scrubbed
Floor hoovered and mopped
Bathrooms, the other place it goes wrong
Scale comes off the taps, shower head, screen and tiles first, with a careful approach on the original chrome and period enamel in the older blocks. Grout is scrubbed back as far as honest effort takes it, and photographed first where it is past saving. Then the rest, in plain order.
Toilet done properly: inside, under the rim, base, cistern, flush flap, hinges, and behind the pedestal where nobody looks but the clerk
Shower screen both sides, tracks and the sealant bead included
Bath, taps, the underside of the taps, overflow and plughole; an original enamel bath gets a low-acid scale remover suited to vintage enamel, not the brute-force descaler that strips the finish
Mirrors and cabinets, and behind them where they come away from the wall
Extractor fan vent wiped and the sealant cleaned to a usable state (re-sealing is a handyman job, not a cleaning one)
Cast-iron column radiator body, valves and pipe-runs, which carry the most scale on a long-let period flat
Floor into the corners, behind the loo and under the pedestal
Bedrooms, reception rooms and everything in between
Inside every wardrobe, drawer and built-in cupboard. The storage in a Sloane Gardens lateral flat can be enormous, so it always gets opened.
Skirting, door frames, doors, handles and finger plates
Light fittings, lampshades, switches, and the ceiling roses, which in a flat with original plaster hold years of dust
Window sills, reveals and frames on the inside, with the tall casement and sash windows in the period blocks needing slow careful work
Radiators behind, under and on top; a cast-iron column radiator takes longer than a modern panel
Walls spot-wiped for marks, with a realistic line drawn, because nail holes and scuffs are a decorator’s bill and not yours to scrub away
Switches, sockets, thermostats, intercoms
Internal doors both sides
The stairs and bannisters where the flat has them
Cobwebs out of the ceiling corners
The picture rail and chair rail collect a fine dust line that is invisible from the doorway and obvious from a step ladder, which is exactly where the clerk’s torch goes, so we bring the ladder.
A few surfaces need their own pass:
Carpets
Professional hot-water extraction is written into a lot of these tenancies with a receipt required at check-out, which is what the carpet cleaning add-on covers on the same visit.
Upholstery
Velvet sofas and upholstered headboards in the furnished lets sometimes want full upholstery cleaning rather than a hoover.
Parquet
Original parquet in the entrance hall of the older Cadogan Estate stock gets a vacuum and a dry buff, never a wet mop, which is what the floor cleaning add-on is for.
External glass
On the upper casements this is normally a window cleaning job, folded into the same visit when the report asks for it.
Then a final walk-through, photographed before and after, every room. That photo set is the evidence you keep.
What very hard water does to a period bathroom here
Sloane Square sits in London’s hard-water zone, and that one detail loses more deposits here than almost anything except the oven.
The region’s chalk and limestone aquifers put the supply at the very hard end, around 280 to 300mg per litre of calcium carbonate.
Calcium builds on taps, shower heads, screens and tile joints faster than tenants expect, and a wipe with a cloth does nothing to it. The clerk checks for it deliberately, running a thumbnail down the tap and looking at the shower screen edge-on against the light.
The period fittings are the catch. None of these take the aggressive descaler a modern flat would shrug off:
an original enamel bath
an old chrome mixer
a cast-iron column radiator with valves furred up over two or three letting cycles
On a long-let 1-bed off Sloane Gardens the descale pass alone is a good ninety minutes of slow work for a two-cleaner team, and that is the figure we plan around rather than discover on the day.
Grout is the other one. Kitchen and bathroom grout is the line between a pass and a deduction more often than anything to do with carpets. We scrub it rather than wipe it, and where it is past saving we photograph the state before we start, so the clerk cannot bill you for wear that was already there at check-in.
That dated photo has settled more disputes than any argument has. A clerk cannot charge a tenant for grout that was already grey in the check-in pictures.
That dated photo has settled more disputes than any argument has.

What it costs, and the maths against the deposit
A Cadogan Estate or Sloane Gardens hand-back takes more hours than a modern studio out in zone 3, and we book enough cleaners for it. The prices below are the same ones the booking widget on this site shows.
Property
Typical duration
Estimated cost
Studio flat (off the King’s Road, Lower Sloane Street)
Those figures assume a flat in normal lived-in shape, with kit and products included. These take longer, and we say so on the phone rather than after:
a long tenancy with heavy wear
a pet household
somewhere that has not had a deep clean in three or four years
Carpet shampoo
£94 for two bedrooms and a living room.
Partial scope
£30 per hour per cleaner, rather than a full hand-back.
Run the maths the way the deposit makes you. A 1-bed at £207 to protect a deposit worth many times that is not really a decision.
Every booking here carries a 48-hour re-clean guarantee. If the agent flags any cleanliness issue inside 48 hours, we come back and redo it free, provided:
you tell us inside that window
the flat is still in the state we left it
The guarantee is the point, because a failed walk-through where the deposit is large is not a small thing to shrug off.
We are on the books of 300+ letting agents, and over the years that work has gone toward £1.2m in deposits recovered for tenants that would otherwise have been lost to cleaning deductions. That number is really the whole job: money that stays with the tenant instead of the landlord.

Three jobs get muddled, and it is worth booking the right one.
Check-in inventory report
The document the clerk writes on day one describing every surface, with photos. It is the benchmark your check-out is judged against, which is why we clean to it and not to a vague idea of “clean”.
End-of-tenancy clean
Built to pass that inventory and get a deposit back, against the agent’s benchmark, with the flat empty and the 48-hour guarantee on it, at a fixed price by bedroom count.
Deep clean
A deep clean resets a home you are keeping, lived-in, with no formal standard to hit, from £26 an hour per cleaner.
Regular domestic clean
A regular domestic clean is ongoing maintenance, from £23 an hour weekly.
Booking it, and how the morning runs
Most weeks we can book a Sloane Square hand-back for the next morning, but the end-of-month and end-of-quarter dates fill fast. Book early for those windows. The steps are simple.
Ring 0333 555 2076 or email office@monstercleaning.com. Price in about three minutes. Give us the postcode, property size, hand-back date and any known problem areas, and mention anything the original check-in report marked “new” or “as new”.
We book you in, ideally the day before the check-out. Allow 7 to 10 days for an end-of-month slot, 3 to 5 days mid-month. Most SW1W mornings start at 8am because the clerk inspection is usually 4pm or 5pm.
Flat empty when we arrive. Furniture out, personal things gone, rubbish cleared. We also do removals if you want the move and the clean on one booking, which helps on these tight permit-parking streets.
Photo proof at the end. Every room, before and after, with an itemised invoice on company-headed paper. That is your evidence pack if the check-out tries to deduct.
Check-out happens. Anything flagged inside 48 hours, we come back and fix it free.
One honest note on access. The streets around the square are permit-controlled and the bays are tight. When you book, tell us:
Parking
The arrangement, whether that is a visitor permit, a meter bay or a porter who will hold a space.
Access
How we get in: concierge, key safe or an agent drop-off.
The lift
Many of these blocks have a single lift the building wants booked for moves.
Flagging that in advance takes the sting out of the day. If your hand-back is tomorrow, ring anyway and we will do what we can.
Questions we get asked
How much is end-of-tenancy cleaning in Sloane Square?
A studio is £156, a 1-bed £207, a 2-bed £243, a 3-bed £339 and a 4-bed £425, and a 5-bed-plus house is quoted from the room count. Every job covers the full 57-point agent-approved checklist. Carpet shampoo, oven and by-the-hour scopes are priced on top. These are full prices, kit included.
Why do Sloane Square hand-backs take longer?
Taller buildings, period fixtures that take longer to descale, high cornicing and agents who inspect to a closer standard. We plan the crew around the hours a Cadogan Estate or Sloane Gardens hand-back actually takes, and the price is the same one the booking widget shows.
Is Sloane Square in Kensington and Chelsea or Westminster?
The residential streets this page works, Sloane Gardens, Cliveden Place, Cadogan Place and Lower Sloane Street, sit in the Royal Borough of Kensington and Chelsea, on the Chelsea side of the Belgravia border. The square is the historic seam between the Cadogan and Grosvenor estates, and the ground east toward Pimlico runs into the City of Westminster. The cleaning standard is the same either way; only the council differs.
Do you cover the Cadogan Estate frontages on Cliveden Place and Sloane Gardens?
Yes. The Cadogan Estate stock on Sloane Gardens, Cliveden Place, Cadogan Place and the streets off the King’s Road is the bulk of our Sloane Square round. On estate stock the hand-back can go through the estate’s own surveyor as well as the agency clerk, so we plan around both inspection lists.
What is the water like around Sloane Square, and does it affect the clean?
It does. Thames Water reports the SW1W supply at roughly 280 to 300mg per litre of calcium carbonate, which is very hard. Lime build-up on the original enamel bath, the chrome mixer, the radiator valves and the kitchen tap base is the most common deduction trigger on a Sloane Gardens hand-back. The descale pass is where the time goes on a long-tenancy 1-bed.
Will the clean cover the cast-iron column radiators in a period mansion flat?
Yes. The radiator bodies, valves and pipe-runs are part of the standard scope. On a flat that has not had the radiators descaled in two or three letting cycles, the valves take a separate pass with a low-acid product, because the valves are the bit the clerk’s torch finds.
Does the Renters’ Rights Act 2025 change anything for Sloane Square tenants?
From 1 May 2026, Section 21 evictions are abolished and every existing assured shorthold tenancy in England converts to a periodic tenancy, so a tenant can give two months’ notice at any point. The cleaning obligations at end of tenancy do not change. The real effect around here is more frequent and less predictable hand-backs, so book as early as you can.
Is carpet cleaning always needed in these rentals?
Often. A lot of Sloane Square tenancies write in a clause requiring professional hot-water extraction with a receipt at check-out, and if you skip it the deduction is close to automatic. We do it on the same visit, so there is one invoice and one receipt for the clerk.
Do you handle the original parquet, marble and period detail?
Yes. Original parquet in an entrance hall gets a vacuum and a dry buff, not a wet mop. A Carrara marble vanity or a polished-plaster wall each takes its own product, so tell us at the booking stage and we match it. Nothing aggressive goes near anything the inventory lists as an original feature.
What happens if the clerk fails the inspection?
The 48-hour re-clean guarantee is the answer. If the report flags any cleaning issue within 48 hours of the hand-back, we come back and fix it free, provided the flat is still as we left it.
What if my landlord disputes the clean after a re-clean?
Escalate to the deposit scheme adjudication. Our invoice, dated photo report and re-clean record are admissible evidence, and a tenant with a complete professional-clean paper trail very rarely loses. Shelter’s guidance on deposits walks through the steps.
Can my agent book this directly?
Yes. We are on the books of 300+ letting agents across London, and around Sloane Square that means regular work with John D Wood & Co, Russell Simpson, Foxtons, Hamptons, Knight Frank and Savills, plus the Cadogan Estate’s in-house team. If your agent rings with the address and the hand-back date, we can invoice the agent and they pass the cost through.
