Who owns the freehold under your flat
Marylebone is not a borough of small private landlords. Most of it sits on two great estates, and which one your flat sits on changes who reads the check-out report. The Howard de Walden Estate holds about 95 acres north and east of Marylebone High Street, has owned that ground since 1879, and manages over 800 buildings through one office. The Portman Estate runs to roughly 110 acres west of Marylebone Lane, was founded in 1532, and covers around 68 streets, 650 buildings and four garden squares. A lot of the original Georgian houses north of Portman Square were rebuilt as mansion blocks a century ago and let on long leases, which is why so much of what you rent here is a flat carved into something older.
The point for a departing tenant is simple. When the landlord is an estate and the day-to-day is run by a managing agent who answers to that estate, nobody on the other side of the check-out is in a hurry to be generous. The clerk’s report goes to a property manager with a file, a budget and a contractor list, and the cleaning line gets treated like every other line: priced, queried, deducted if it is soft. That is the real reason a Marylebone end of tenancy is unforgiving. It is not the postcode being fussy. It is an institution checking its own asset back in.
There is a second consequence people miss. An estate that has held the same ground for well over a century thinks in long horizons, so it maintains its buildings to a standard and expects them handed back at that standard. The agent who manages the flat for the estate uses the same handful of cleaning and inventory contractors across a whole street, which means the clerk inspecting your flat and the cleaner the agent would send to put it right are often part of the same loop. The clerk knows precisely what that loop’s clean looks like. Hand back something visibly below it and the report does not need to argue; the gap speaks for itself, and the deduction follows the contractor’s own day rate, not a number you can haggle.
The Howard de Walden side also created Marylebone Village, the run of independent shops and restaurants along Marylebone High Street, as a deliberate piece of place-making. That is not trivia for a tenant. It tells you the estate actively curates the area’s value, and a landlord who curates value protects it at the point a flat changes hands. The check-out is where that protection is enforced, line by line, on you.
The flat types behind a W1 postcode
W1G and W1U cover four broad kinds of home, and each one fails the inventory in its own way. Knowing which you are handing back tells you where the deductions hide.
- Period flat in a Georgian terrace
- A townhouse on Wimpole Street, Devonshire Place or around Portman Square split into flats. High ceilings, deep skirting, original sash windows and often a working fireplace. The clerk goes for the cornice line, the picture rails, the window reveals and the marks ovens leave on a kitchen that was shoehorned into a back room.
- Mansion-block lateral flat
- The Edwardian red-brick blocks the estates built on Marylebone Lane, Chiltern Street and the streets off Marylebone High Street. Long internal corridors, a service stair, parquet or wide boards, heavy panelled doors. Communal parts are inspected too, so the front door, the mat well and the inside of the letterbox count.
- Mews house
- Devonshire Mews, Wimpole Mews and the cobbled rows behind the main streets, once stables, now small two-floor houses. A garage or undercroft at ground level collects oil and dust, the stair is steep and narrow, and the clerk checks the roof terrace door track and the small rooms upstairs hard.
- Prime new-build or full refurbishment
- A Marylebone Square apartment or a gutted-and-rebuilt flat handed over in show-home order. Engineered floors, stone bathrooms, integrated appliances, underfloor heating. The inventory standard is the highest of the four because the check-in photographs show it flawless, so any haze on glass, any grout shadow, any fingerprint on a handle is a logged drop.
One building can hold three of these at once. We do not send the same clean to all of them. The mansion-block job is about communal parts and parquet; the new-build is about streak-free stone and glass; the period flat is about the bits a high room has that a normal flat does not. The clerk knows which type they are standing in. So do we.
The reason this matters in money terms is that each type carries its deductions in a different room. A period conversion loses deposits on the bits the original house kept, the cornice run, the picture rails, the deep sash boxes, and on a kitchen that was fitted into a space never built for one, so the extraction and the unit tops are where a clerk goes. A mansion-block flat loses them on the communal approach and the parquet, because the lease makes those the tenant’s concern up to the front door. A mews house loses them downstairs, on the garage or undercroft slab and the awkward stair, and a prime refurbishment loses them on glass and grout, because the check-in there was photographed flawless and the clerk only has to find one haze to write a line. Tell us the building and we already know the half-dozen places the report will land.
The clerk knows which type they are standing in. So do we.
The company let and the medical tenant
Marylebone rents differently from most of London. A large share of these flats go on company lets, taken by an employer for a relocating executive, or to professionals working the Harley Street and Wimpole Street medical area, which runs across Weymouth Street and Devonshire Place and holds well over a thousand practitioners. That changes the check-out in two concrete ways.
First, the person moving out is often not the person who pays. A company let is checked back in by a relocation agent and an accounts department, and they reconcile the clerk’s report against the deposit to the line. A medical tenant on a fixed posting is frequently gone the same week the next one arrives, so the agent wants the flat re-let in days and has no patience for a clean that needs doing twice. Both of those make the inventory the only thing that matters, because the paperwork outlives the tenant.
Second, the standard does not soften for a short stay. A six-month corporate let is judged against the same check-in photographs as a three-year one. We get asked, fairly often, to clean a flat that genuinely looks fine to the person leaving it. It looks fine. It will still be measured against a document that recorded it professionally cleaned, and against a clerk who has the photographs open on a tablet while they walk the rooms.
The licence your Marylebone landlord now needs
Since 24 November 2025 Westminster City Council has run a selective licensing scheme for privately rented homes across 15 of its 18 wards. Marylebone is in it. Only Pimlico South, St James and Vincent Square sit outside, so a flat let in W1G or W1U almost always needs a licence, at a fee of roughly £1,000 per property. You can read the scheme on the Westminster City Council selective licensing page.
This is not a cleaning rule, but it presses on your check-out anyway. A licensed property is a property the landlord is being watched on, which means the managing agent is keeping condition records tighter than before, and a clean check-out report is part of how they show the flat is being run properly between tenancies. When the file is being inspected, nobody lets a borderline cleaning line through to keep a tenant happy. The licence has made the whole estate-and-agent machine more careful, and careful, at check-out, costs the tenant who under-cleaned.
The deposit law and the paper under it
Two laws decide what a Marylebone landlord can actually take, and a tenant who knows them argues from a stronger place.
Your deposit must sit in one of the three government-backed schemes, the Tenancy Deposit Scheme, the Deposit Protection Service or mydeposits, and it must be protected within 30 days of being paid. The gov.uk guidance on deposit protection schemes sets out the duty and the prescribed information the landlord owes you, and Shelter’s page on checking your deposit is protected walks through how to confirm it. If the deposit was never protected, the cleaning argument is the least of the landlord’s problems.
The amount is capped. Under Schedule 1 of the Tenant Fees Act 2019 a deposit cannot exceed five weeks’ rent where the annual rent is under £50,000, or six weeks’ rent where the annual rent is £50,000 or more. Plenty of Marylebone flats sit the wrong side of that £50,000 line, so the six-week cap is the one that bites here, and it means the sum at stake at check-out is genuinely large. A landlord still cannot make a professional clean a contractual condition; the Tenant Fees Act stopped that. What they can do is deduct for a flat returned below the check-in standard, which is a different thing and the thing that actually happens.
The Renters’ Rights Act 2025 received Royal Assent on 27 October 2025, and the bulk of it came into force on 1 May 2026. It reshapes how tenancies end and rebalances a good deal between landlord and tenant. It does not abolish the inventory or the deposit deduction for cleaning, so the practical lesson for a Marylebone check-out is unchanged: the dated, photographed check-in report is the document you are judged against, and an itemised professional cleaning invoice is the evidence that answers it.
It is worth being plain about a few terms, because the deductions argument is usually lost or won on what these actually mean.
- Check-in inventory
- The dated, photographed schedule of the flat’s condition at the start of your tenancy. On a W1 estate let it almost always records a professionally cleaned flat. It is the single document the check-out is measured against, so it is the document we clean to.
- Deposit cap
- The legal ceiling on the deposit: five weeks’ rent where annual rent is under £50,000, six weeks’ where it is £50,000 or more, under Schedule 1 of the Tenant Fees Act 2019. Many Marylebone flats trip the six-week figure, so the sum at risk is large.
- Deposit protection scheme
- One of the Tenancy Deposit Scheme, the Deposit Protection Service or mydeposits. Your deposit must be in one within 30 days of payment, and each runs the free dispute service that decides a contested cleaning deduction.
- Fair wear and tear
- The normal ageing a flat takes from ordinary living, which a landlord cannot charge you for. A dirty oven is not wear and tear; a carpet thinned by three years of use is. Clerks separate the two, and so should you when you read the report.
Parking a van in zone F
This is the part of a Marylebone job we plan around hardest, and it is worth being straight about. Marylebone sits in Westminster controlled parking zone F, which also covers Fitzrovia and the Hyde Park side, and there is no soft option for a working van here. Bays are pay-by-phone, expensive by the hour, time-limited on the busy streets, and a single yellow on much of Marylebone High Street and the medical roads means no loading at the wrong time. The parking is the worst part of working W1, and any cleaning firm that pretends otherwise has not done it.
We deal with it by sending kit-bag teams who do not need a van parked at the door, by booking the longer jobs early so we are loading in before the streets fill, and by costing the parking into the fixed quote instead of finding it on the day. The whole West End sits on ULEZ, which has run since 2019 and now covers the lot, at £12.50 a day for a non-compliant vehicle, so our vans are compliant and that charge never lands on you. None of this is your problem to solve. It is ours, and we would rather say so than surprise you with it.
The 57-point clean, room by room
The 57-point checklist is the agent-approved page, not a marketing list. It is the same sheet a W1 inventory clerk effectively works from, which is why a flat cleaned to it tends to pass first time. Here is where the work actually goes in a Marylebone flat.
Kitchen. This is where most deductions are born. The oven comes apart, the door glass is split and cleaned between the panes, the racks and the interior are degreased to bare metal. The extractor hood and its filter, the bit a domestic clean skips, get done because the clerk checks it. Behind and beside the integrated appliances, the washing-machine drawer and door seal, the splashback grout, the inside and top of every wall and base unit. On a prime fitted kitchen the stone is finished streak-free, because the check-in photographs show it that way.
Bathrooms. Limescale is the Marylebone tell. Hard London water leaves screens, chrome and stone fogged, and a clerk runs a thumb down the shower glass first thing. Descaled glass and taps, grout brought back, extractor vent cleared, the underside of the rim and the hinge points done. On a stone bathroom we use what will not etch the surface, because the wrong product is itself damage.
Reception and bedrooms. Skirting behind where furniture stood, the cornice and picture-rail line a high Georgian room has, sash window reveals and the runners, internal glass, every door top and the handles. Parquet and wide boards are cleaned to suit the finish, not flooded. Built-in wardrobes are done inside, top and back, which is exactly where a clerk looks because it is exactly where a tenant does not.
The bits a Marylebone flat adds. A high Georgian room is taller than a normal flat, so dust sits on ledges a domestic clean never reaches: the cornice, the picture rail, the tops of doors that run close to two and a half metres, the deep window reveals on a sash. A mansion-block flat brings a long internal corridor, a service stair and heavy panelled doors that all hold marks. A mews house brings a steep narrow stair, a roof-terrace door track that collects grit, and a ground-floor garage or undercroft that drops oil and dust into the rest of the house. We clean these because the clerk checks them, and they are exactly the lines a flat-rate domestic clean leaves behind.
Carpets and soft furnishings are a separate decision, covered below. The base clean is thorough, but a worn-in stair carpet in a mews house or a marked sofa in a let-furnished flat needs the machine, and a clerk knows the difference between hoovered and cleaned.
That 97% first-time pass rate is the number that matters to you, because it is the chance the clerk signs the flat off without sending us back. When the other 97% does not happen, the 48-hour re-clean guarantee covers it: if the clerk or agent challenges the work within 48 hours, we return and put it right at no cost. We did not invent the standard. We learned it from being on the books of 300+ letting agents and watching what their clerks actually mark.
Where Marylebone deposits actually go
Across the W1 check-outs we attend, cleaning deductions cluster in the same places, and they are predictable enough to plan against.
The oven and the kitchen extractor lead, every time. Then limescale on bathroom glass and chrome, because the water here guarantees it and a clerk checks it first. Then the things a high room adds that a normal flat does not: cornice, picture rails, the tops of tall doors, deep sash reveals. Then communal touchpoints on a mansion-block flat, the front door and letterbox the clerk passes on the way in. Then built-in storage, cleaned at the front and nowhere else. On a mews house, add the garage or undercroft floor and the roof-terrace door track. On a prime new-build, add every pane of glass and every run of stone grout, because the check-in standard there is flawless and anything short of it is a logged drop.
None of this is exotic. It is the same list the clerk carries, which is the whole reason we clean to that list and not to a domestic idea of done.
What it costs on a Marylebone flat
We price the flat, not the hour. You get a fixed quote before we start, and the cleaners stay until the checklist is finished rather than until a clock runs out, which on a Marylebone check-out is the only fair way to do it. An hourly rate rewards a firm for being slow; a fixed price for a passed inventory does not.
The quote follows the size and the state of the flat. A studio or one-bed off Marylebone Lane is one number; a lateral three-bed in a Wimpole Street mansion block, with the corridor length and the extra bathrooms those carry, is another. What moves the price is condition and the add-ons below, not a meter. We tell you the figure up front, the parking is already inside it, and it does not change unless you change the job.
Carpets, upholstery, the oven as a deep specialist job and exterior glass are quoted as named extras, because not every flat needs them and you should not pay for what yours does not. If the carpets in a let-furnished flat are marked, our deep carpet cleaning with hot-water extraction is the line that saves the carpet deduction. Tired sofas and chairs are the same story with upholstery cleaning. A heavily built-up oven can be booked as standalone oven cleaning, the parquet or stone floors as floor cleaning, and where the inventory demands clean glass outside, window cleaning with fed-pole purified water covers it. If you are moving locally, our removals team can run alongside the clean. End of tenancy is one of several jobs we do; the wider deep cleaning and domestic cleaning services are there when the flat is staying lived-in. Full guidance and a price are on the prices page and the end of tenancy cleaning hub.
A Weymouth Street job from last month
A two-bed lateral flat on Weymouth Street, a Howard de Walden let, end of a company tenancy for a consultant on a hospital posting. The relocation agent had the next tenant lined up for nine days later, so there was no slack for a second visit. The tenant thought the flat was fine. By a domestic standard it was.
The clerk’s likely list was the usual W1 one: oven and extractor, limescale on two bathrooms, cornice and picture-rail dust in a high reception, the front door and letterbox on a mansion-block entrance, built-in wardrobes done only at the front. We took the flat to the 57-point sheet, split and cleaned the oven glass, descaled both shower screens, did the reveals and the rails, and cleaned the wardrobes top and back. The check-out passed first time, no return, no cleaning deduction. The accounts department released the deposit in full because the report and our dated invoice agreed. That is the job, and it is why the inventory document, not the tenant’s eye, is the thing we clean to.
The check-out passed first time, no return, no cleaning deduction.
Booking it around the clerk
The single thing that decides whether this goes smoothly is order. Clean after the furniture and the people are out, and before the inventory clerk arrives, with a real gap between the two. We have seen Marylebone tenants lose money purely because the clean was squeezed against a same-day check-out and the clerk walked in on a flat still drying.
Tell us the check-out date and time when you call. We book the clean to land the day before, or that morning with hours to spare, so the flat is dry, aired and finished when the clerk opens the door. We work seven days a week, which matters here because company-let check-outs and estate inspections do not all fall on weekdays. Empty flat is best; if it has to be part-furnished, say so and we plan round it.
To book, call 0333 555 2076 or use the contact page. Tell us the postcode, the flat size, the check-out time and whether carpets or the oven need the specialist line. You get a fixed price for that flat, a slot that fits the clerk, and the 48-hour re-clean guarantee behind it. If you want it in one sentence: book the clean into the gap between your move-out and the clerk, and let us hold that gap for you.
Around Marylebone, streets and services
We cover the whole of Marylebone, W1G and W1U and the NW1 fringe up towards the station: Marylebone High Street and Marylebone Lane, the Wimpole Street and Harley Street medical roads, Chiltern Street, Devonshire Place and the mews behind them, the Portman Square side and the blocks around Manchester Square. Baker Street station puts five lines on the doorstep, the Bakerloo, Circle, Hammersmith and City, Jubilee and Metropolitan, with Bond Street a short walk south for the Jubilee and the Elizabeth line, and Marylebone station about 300 metres on for National Rail. It is one of the best-connected squares of London to clean in, which is also why the lets turn over fast.
We run the same inventory-standard end of tenancy clean across the neighbouring W1 and Westminster patches. East into the offices and flats of Fitzrovia, down the retail spine through Bond Street and Oxford Street, and across the estates of Mayfair and the streets of Soho. North of the Marylebone Road we work Regent’s Park and St John’s Wood, and west towards Paddington, Bayswater and Maida Vale. South across Westminster we cover Pimlico. If your move is a short one, the same crew can clean the old flat and the new one on the same day.
Questions Marylebone tenants ask
Do I really need professional end of tenancy cleaning for a Marylebone flat?
Legally, no. Since the Tenant Fees Act 2019 a landlord cannot make a professional clean a contractual condition. In practice the flat was almost certainly cleaned professionally for the previous tenant, so the check-in inventory you signed records a professional standard, and an amateur clean reads as a drop the clerk marks. On an estate-managed company let the accounts side reconciles every line, so a dated professional invoice is usually what settles it in your favour.
What does the 48-hour re-clean guarantee actually cover?
If the inventory clerk or the agent challenges our work within 48 hours of the clean, we come back and put it right at no extra charge. It is tied to the agent-approved 57-point checklist, so it covers the cleaning the clerk is entitled to mark, not later damage or wear that has nothing to do with the clean.
My flat is on the Howard de Walden or Portman estate. Does that change anything?
It changes who reads the report, not what we clean to. An estate-managed flat is checked back in by a managing agent with a budget and a contractor list, so borderline cleaning lines tend to be deducted rather than waved through. We clean to the inventory document either way; the estate context just means the document is read strictly.
It was only a six-month company let. Is the standard lower?
No. A short corporate or medical let is judged against the same dated check-in photographs as a long tenancy. The flat being handed back may look fine to you and still fall short of the professionally cleaned standard the inventory recorded, which is exactly the gap a clerk is paid to find.
How much is end of tenancy cleaning in Marylebone?
It is priced on the flat, not by the hour, so a studio off Marylebone Lane and a lateral three-bed in a Wimpole Street mansion block are different numbers. You get a fixed quote before we start, with the parking already inside it, and it only changes if you change the job. Call 0333 555 2076 for the figure on your flat.
Does the new Westminster licensing scheme affect my deposit?
Not directly, but it tightens the check-out. Westminster’s selective licensing scheme has covered Marylebone since 24 November 2025, so the managing agent is keeping condition records closer and is less likely to let a soft cleaning line through. It makes a clean, well-documented hand-back matter more, not less.
Where should the clean sit around my check-out appointment?
After the flat is empty and the furniture is gone, and before the inventory clerk arrives, with a real gap between the two so the flat is dry and aired. Tell us the check-out time when you book and we set the clean the day before or that morning with hours to spare. Squeezing it against a same-day inspection is how tenants lose money they did not need to.
Can you also do the carpets, oven and windows for the inventory?
Yes, as named extras quoted separately so you only pay for what your flat needs. Marked carpets get deep carpet cleaning with hot-water extraction, a built-up oven gets specialist oven cleaning, and where the inventory requires clean glass outside we use window cleaning with fed-pole purified water.
What if the deposit deduction for cleaning is unfair?
You can dispute it. Your deposit is held in the Tenancy Deposit Scheme, the Deposit Protection Service or mydeposits, and each runs a free dispute-resolution service, normally with a three-month window after you move out. The side with dated invoices and photographs tends to win, which is why we always leave you an itemised invoice.
Do you cover the rest of W1 and the nearby Westminster areas?
Yes. We run the same inventory-standard clean across Fitzrovia, Mayfair, Regent’s Park and out towards Paddington and Bayswater. If you are moving locally the same crew can clean both flats on one day.
