On a Cromwell Road mansion flat the clerk’s eyes go up before they go anywhere near the kitchen: to the cornice run and the picture-rail top twelve feet above the reception floor, where a year of dust has settled on plasterwork no household duster ever reaches.
That grey band is the classic South Kensington deduction on this stretch, opposite the Natural History Museum, and it is the thing a quick clean cannot touch without the right pole gear. We do the SW7 hand-back clean to the 57-point agent-approved checklist, at a fixed price by bedroom count or £30 per cleaner per hour for a part property, with a 48-hour re-clean guarantee measured against the check-out report itself. Ring 0333 555 2076 for a price.

Because the flats on this road were built tall, and the check-in report told the clerk to look up.
- When you moved into a mansion-block flat here, a clerk wrote a line-by-line inventory, almost always with photographs. On a twelve-foot ceiling the plaster cornice, the ceiling rose and the picture-rail top each get their own entry, marked “good” or “as new”.
- They were true on the day, because the flat had just been professionally cleaned.
- At check-out a different clerk compares, line by line, and anything materially worse than the check-in entry, past fair wear and tear, is chargeable against your deposit.
You are marked against a professional clean, and no domestic dustpan reaches a cornice at head height plus a metre, so the DIY move-out loses that band by default.
The money here is not abstract. On the Cromwell Road deposits held in a scheme, five figures is ordinary rather than exceptional, so the inspection is genuinely adversarial and the clerk is paid to find faults.
Three things fail more than anything else on the grand blocks:
- the high-level dust band on the cornice and above the picture rail
- the putty bead and pane corners on the tall stucco bay window
- the lime haze on the original basin and mixer
On the serviced flats at the Earl’s Court end the pattern shifts to integrated-appliance seals, carpet-edge dust and the marks around a wall-panel control.
Two bits of law sit behind all of this.
- The Tenant Fees Act 2019
- A landlord cannot make professional cleaning a contractual condition, so nobody can force you to book us. It also caps your deposit at five weeks’ rent, still a very large sum on Cromwell Road rents.
- Damp
- Where we find genuine damp behind a wardrobe or in a cold bathroom corner we photograph it, because that is a landlord repair matter, not a tenant cleaning failure.
What 1 May 2026 changed for a museums-quarter move-out
The Renters’ Rights Act 2025 went live on 1 May 2026.
- Section 21
- No-fault eviction is gone.
- Existing tenancies
- Every existing assured shorthold tenancy in England has become a periodic tenancy.
- Notice
- A tenant can now give two months’ notice at any point rather than waiting out a fixed term.
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, and the deposit maths is what it was the week before.
What changed is timing, and timing bites hard on Cromwell Road, where the tenant pool is unusually international and short-dated:
- diplomatic staff at the embassies on the road
- corporate lets through the mansion blocks and serviced apartments
- visiting academics near Imperial College
- hotel-adjacent pied-a-terre flats
Let those tenancies unwind on a rolling two months instead of a fixed end date and the hand-backs get more frequent and far harder to predict.
The practical takeaway is dull and it pays for itself. Book earlier than you used to. The slot you want, on the morning your clerk is coming, is gone if you leave it to the day before.
The cleaning side of a move-out did not change at all.
The 57 things we work through, and the ones that lose deposits
Every Cromwell Road booking runs to a 57-point checklist built over a decade of South Kensington check-outs and tuned to what these clerks flag. The full list comes with the job.
Below is the focused version, the points that decide an SW7 hand-back. It starts high because the ceiling line is where the money goes.
The ceiling line, the bay and the hall
- Cornice perimeter, ceiling rose and picture-rail top in every reception room, worked on a pole-mounted soft head because the band sits a metre above head height
- The tall stucco bay window: putty bead, sill, and the corner of every pane on the original frame
- The double-height entrance hall many Cromwell Road flats carry, its high cornice and the light fitting in the void
- Painted secondary stair and its dado
Bathroom and kitchen
- Original basin, bath and mixer descaled with a mild product that will not etch a century-old chrome or brass plate
- Shower screen and its tracks, tile grout floor to ceiling, tap aerators and the shower rose
- Oven cleaned not wiped, door glass split where the glass allows so the film between the panes comes out, plus the extractor baffle and the integrated dishwasher seal on the modern kitchens
- Every cupboard inside and out including the carcase tops, and the gaps pulled out behind the fridge, the washer and the dishwasher
Throughout the flat
- The wardrobe, drawer and built-in cupboard interiors throughout
- Behind every radiator, the period cast-iron ones included, plus switches, sockets, door tops, the letter-flap and the meter cupboard
- On the Earl’s Court-end laterals and serviced flats: carpet-edge skirting dust, wall-panel heating controls and the smart-lock keypad the previous tenant thumbed daily
Two of those often need a pass of their own.
- Bedroom carpets
- Professional hot-water extraction is written into many of these tenancies as a hard line at check-out, which the carpet add-on covers on the same visit.
- Reception floors
- These stay a dust-and-edge job, because the clerk wants a clean surface, not a re-finish.
We photograph each completed point, before and after, and the timestamped set goes out with the invoice as your evidence pack.
What 300ppm water does to a century-old basin
South Kensington sits deep in London’s hard-water zone, and that fact loses more deposits on this road than anything except the oven.
- The supply
- Thames Water runs the SW7 supply at just over 300ppm calcium carbonate, near the top of the national range, because the water drains off chalk before it reaches the taps.
- Where it builds
- Calcium builds on taps, the shower rose, the screen and the tile joints faster than tenants expect, and a wipe with a cloth does nothing to it.
The clerk checks:
- a thumbnail dragged down the tap
- the screen held edge-on to the light
- the rose pulled in close
The catch on Cromwell Road is the age of the fittings. On the older mansion-block flats the basin and the bath-shower mixer are often original chrome and brass from when the block went up, and the brute-force descaler a modern flat would shrug off strips the plating clean off those.
So the lime work here is slow: a mild acid left to sit and do the job rather than scrubbed hard, because a scratched original mixer is a bigger deduction than the lime ever was.
Grout is the other quiet one, the line between a pass and a charge more often than carpets are. Where a run of it is past saving in a long let we photograph the state first, so the clerk cannot bill you for wear already there in the check-in pictures.
A scratched original mixer is a bigger deduction than the lime ever was.
Cromwell Road end to end: the stock changes as the road runs west
Cromwell Road is the grand A4 avenue through South Kensington, running roughly a mile and a half from the museums quarter west to the Earl’s Court Road junction, where it becomes West Cromwell Road toward West Kensington.
A serviced pied-a-terre at the Earl’s Court end and a twelve-foot-ceilinged flat opposite the V&A share the same road and almost nothing else. We work it as three kinds of stock.
The grand mansion blocks by the museums quarter
This is the genuine Cromwell Road specialism. The stretch nearest the museums is lined with tall white-stucco Victorian and Edwardian mansion blocks, the frontage looking straight across at the Natural History Museum and along to the V&A and Science Museum. The flats inside run to:
- twelve-foot ceilings
- deep plaster cornices on every reception perimeter
- ceiling roses
- a picture rail at roughly two and a half metres
- often a double-height entrance hall
They fail on what grand blocks always fail on:
- the high-level dust band no household tool reaches
- the tall bay-window bead and pane corners
- the painted secondary stair
- a century of chalk hardness on the original basin
It is a taller, heavier job than the flats further west, at the same price per bedroom.
Emperor’s Gate, Ashburn Gardens and the lateral conversions
North and south off the road, on Emperor’s Gate, Ashburn Gardens, Ashburn Place and Courtfield Gardens, the stucco terraces and purpose-built blocks have been carved into flats and lateral conversions: two neighbouring flats knocked into one wide floor, so the run of reception rooms and the cornice work double.
Emperor’s Gate sits on the north side of Cromwell Road between Grenville Place and Ashburn Gardens, typical of the pattern. The giveaways:
- the long cornice perimeter across a wide lateral
- the picture-rail top in every joined room
- the period basin lime in what is usually more than one bathroom
The Earl’s Court end: serviced flats and modern West Cromwell Road blocks
West toward the Earl’s Court Road junction the stock turns over fastest of all. Ashburn Place and the road frontage carry:
- serviced and short-let apartments
- hotel-adjacent flats around the converted townhouse hotels that have clustered here since Bailey’s Hotel first drew them in
- the newer redevelopment blocks on West Cromwell Road
These come with integrated kitchens, wall-panel heating controls, far more carpet than the period stock, and their own rules on lift use and service entrances. The work list is different, the per-bedroom price is the same.

What it costs, and the maths nobody runs until the deposit is at stake
| Property | Typical duration | Estimated cost |
|---|---|---|
| Studio or serviced flat (Ashburn Place, West Cromwell Road) | 3-4 hours, 1-2 cleaners | From £156 |
| One-bed conversion or mansion flat | 4-5 hours, 2 cleaners | From £207 |
| Two-bed mansion flat or lateral | 5-7 hours, 2-3 cleaners | From £243 |
| Three-bed mansion flat or wide lateral | 6-8 hours, 3 cleaners | From £339 |
| Four-bed lateral (Emperor’s Gate, Courtfield Gardens) | 8-10 hours, 3-4 cleaners | From £425 |
| Carpet shampoo add-on | Same visit | From £29 a room |
| Oven as a standalone spec | 1.5-2 hours | From £77 |
The high-level cornice work and the pole gear it needs are real extra labour on Cromwell Road, and a wide Emperor’s Gate lateral is larger than a borough-average home. So we plan more hours and a bigger crew; the price stays the one for the bedroom count.
The add-ons stay at the ordinary rate:
- Carpet
- £29 a bedroom, £36 a living room and £94 for two bedrooms and a living room
- Oven
- £31 for a single and £62 for a double or a 90cm range
- By the hour
- For a top-up team rather than a full hand-back, it is £30 per cleaner, kit and products included.
Those figures assume a flat in normal lived-in shape; a long let with heavy wear takes longer, and we say so on the phone, not after.
Run the maths the way the deposit makes you. A one-bed at £207 to protect a deposit capped at five weeks’ rent, on Cromwell Road rents, is barely a decision.
Every booking carries the 48-hour re-clean guarantee: if the clerk flags a cleaning point within 48 hours of us finishing, we come back and put it right free, as long as:
- you tell us in that window
- nobody has moved in
We are on the books of 300+ letting agents who recognise our signed checklist, and over the years tenants working this way have recovered £1.2m in deposits that would otherwise have gone on cleaning deductions. That last figure is really the whole job.
Three different jobs get muddled at move-out, 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 rather than to a generic idea of clean.
- End-of-tenancy clean
- Built to pass that inventory and get a deposit back, against the letting-agent benchmark, with the flat empty and the 48-hour re-clean guarantee on it, at a fixed price by bedroom count or £30 an hour per cleaner for a part property.
- Deep clean
- A reset of a home you are keeping, lived-in, with no formal standard to hit and no clerk arriving. From £186: £26 per cleaner per hour for two cleaners and at least three hours, plus £30 for kit.
- Regular domestic clean
- Ongoing upkeep on a weekly or fortnightly rota, from £23 an hour, a different service run by a different team.
Licensing, the clerk, and who actually needs a licence
The Royal Borough of Kensington and Chelsea runs mandatory HMO licensing, and on top of it a borough-wide additional HMO scheme. Whether either touches your flat depends on who lives in it.
- Additional HMO scheme
- Took effect on 1 June 2023 and runs to 31 May 2028. It catches houses in multiple occupation outside the mandatory rules, which in practice means most shared houses and flats let to three or more people forming two or more households.
- Selective licensing
- There is no selective licensing scheme anywhere in the borough, so an ordinary single-household let needs no licence at all.
Most Cromwell Road hand-backs are exactly that, so no licence is in play. If you are a landlord with a sharer let on a converted flat, the additional scheme applies and the clerk will ask.
The clerks the SW7 agents send in are not generalists. They know the corridor.
- Foxtons work the Earl’s Court end from their Old Brompton Road office.
- Savills, Chestertons and Marsh and Parsons each run their own clerk panels across South Kensington.
- The serviced-let firms use their own inspectors.
The walk goes up first:
- the cornice and picture-rail top and the double-height hall
- then the tall bay-window bead and every pane corner
- the period basin lime, the oven glass and extractor baffle
- then the wardrobe interiors and behind every radiator with a torch
A well-documented job rarely gets an argument, which is the point of handing over a dated photo set rather than a promise.
Booking it, and the A4-and-access problem
South Kensington bunches its check-outs at month-end, and the international and corporate lets on Cromwell Road add their own clustering around posting rotations and term dates, so the good slots go early. Ring ahead. The steps are simple.
- Ring 0333 555 2076. A price in a few minutes. Give us the postcode, the bedroom count, the check-out date and time, and the name of your letting agent, and mention anything the check-in report marked “good” or “as new”.
- We confirm a fixed price by return. No quote visit on a standard mansion-block flat or lateral, we have cleaned enough of them. Allow 7 to 10 days for an end-of-month slot, 3 to 5 mid-month.
- Flat empty when we arrive. Furniture out, personal things gone, rubbish cleared, so the team can reach the skirting, the cupboard carcases and behind the appliances.
- Photo proof at the end. Every room, before and after, timestamped against the 57-point checklist, with the invoice on company-headed paper. That is your evidence pack.
- Check-out happens. Anything the clerk flags inside 48 hours, we come back and fix free.
One honest note on access, because it is the real friction here. Cromwell Road is the A4, a red-route trunk road carrying traffic toward Heathrow, so there is no pulling up on the road itself and the loading has to be worked onto the tight controlled-parking side streets off it.
Tell us the arrangement when you book:
- Mansion blocks
- The way in is usually a concierge desk or a porter rather than a key.
- Serviced-let blocks
- They have their own lift and service-entrance rules.
Confirming that in advance takes the sting out of the morning.
We also run removals if you want the move and the clean on one booking, which helps when the road frontage rules out a simple park-and-carry. The same round covers the neighbouring SW7 corridors:
- Gloucester Road end of tenancy cleaning for the cross-street that meets Cromwell Road at the tube
- Queen’s Gate end of tenancy cleaning for the grand avenue a block east
Questions we get asked
How much is end of tenancy cleaning on Cromwell Road?
We charge £156 for a studio, £207 for a one-bed, £243 for a two-bed, £339 for a three-bed and £425 for a four-bed. The high-level cornice work and the scale of a twelve-foot-ceilinged mansion flat or a wide Emperor’s Gate lateral add hours, which we plan into the crew. Add-ons stay at the normal rate: carpet from £29 a bedroom, £36 a living room, £94 for two bedrooms and a living room, and oven at £31 single, £62 double or a 90cm range.
Will the clerk really check the cornicing twelve feet up?
Yes. On a Cromwell Road mansion flat the cornice perimeter and the picture-rail top are named entries on the inventory and the single most common deduction on the road. The clerk walks in and looks up before anything else, and the dust band is easy to see from floor level once you know to look. We carry pole-mounted soft heads sized for the cornice channel and do the perimeter of every reception room and the entrance hall.
Do you cover the mansion blocks opposite the Natural History Museum?
Yes. The tall white-stucco mansion blocks fronting Cromwell Road by the museums quarter, looking across at the Natural History Museum and along to the V&A and the Science Museum, are the bulk of our SW7 4 and SW7 5 work. They are a taller, heavier job than the flats further west, and we carry the pole gear sized for these ceilings specifically.
Is SW7 water hard enough to leave lime on period fittings?
Yes. Thames Water runs the South Kensington supply at just over 300ppm calcium carbonate, near the top of the London range because the source drains off chalk. The original chrome and brass basins and bath-shower mixers on the older mansion-block flats show the haze first. We descale them with a mild product that suits period plate, not a strong acid that strips it.
Do you cover the wide laterals on Emperor’s Gate and Ashburn Gardens?
Yes. Emperor’s Gate, Ashburn Gardens, Ashburn Place and Courtfield Gardens are full of lateral conversions where two flats were knocked into one wide floor, so the run of reception rooms and the cornice work double. We price by bedroom count whatever the layout, and we bring enough cleaners to work a wide lateral in a single morning.
What about the serviced and short-let flats at the Earl’s Court end?
We cover them. Ashburn Place and the West Cromwell Road frontage carry serviced apartments and hotel-adjacent short lets that turn over fast, with integrated kitchens, wall-panel controls and more carpet than the period stock. The work list is different, the per-bedroom price is the same, and we clean to the operator’s checklist when you send it.
How quickly can you book a Cromwell Road clean?
Usually next day or the day after. SW7 sits inside our regular Kensington round and we hold capacity on it most weeks. A check-out morning is fine as long as you ring the day before, ideally before 8am so we can slot the team ahead of the clerk.
Can you clean on the morning of check-out?
Yes. We run early starts on Cromwell Road most weekdays, arriving at 8am or 9am and working straight through to finish before the clerk’s usual early-afternoon slot. On a three-bed mansion flat that is a team of three or four for roughly four to five hours.
Do you re-wax or restore the reception floors?
No, and you should be wary of anyone who offers it as part of a move-out clean. We do the dust pass and the edge band along the skirting, which is what the clerk marks. A parquet or engineered floor that genuinely needs sanding and re-finishing is a specialist flooring job, not end-of-tenancy work.
Can you do the carpets on the same visit?
Yes if you book it in. Carpet shampoo is a separate add-on, £29 a bedroom and £36 a living room, or £94 for two bedrooms and a living room. We run the carpet pass after the dust pass so the lifted grime ends up on the wet extractor head rather than back down on the hard floors we have just finished.
Is there really a re-clean guarantee?
Yes. Every Cromwell Road booking carries the 48-hour re-clean guarantee: if your clerk flags a cleaning point within 48 hours of us finishing, we come back and put it right at no charge, provided you tell us in that window and nobody has moved in. It applies whether your agent is Foxtons, Savills, Chestertons, Marsh and Parsons or one of the serviced-let firms at the West Cromwell Road end.
Does RBKC need a special licence on a Cromwell Road let?
Only if it is a house in multiple occupation. The Royal Borough runs mandatory HMO licensing plus a borough-wide additional HMO scheme, in force from 1 June 2023 to 31 May 2028, catching most homes let to three or more people from two or more households. There is no selective scheme covering ordinary single-household lets, and most Cromwell Road hand-backs are exactly that, so no licence is in play at check-out.
What is the 57-point checklist?
It is the 57-point agent-approved checklist we run on every clean: kitchen, bathrooms, bedrooms, reception rooms, entrance hall, secondary stair, then the throughout list of switches, doors and radiators. Each line is a specific item. The team lead signs it off on a tablet with a timestamped photo of each point, and you get the whole set by email. That dated report is the evidence that has helped tenants recover £1.2m in deposits.
