The stucco villas that line Belsize Park Gardens and the streets around them went up between 1852 and 1878, and almost none of them are still one house. They were carved into flats decades ago, two and three bedrooms mostly, and that single fact shapes every end-of-tenancy clean in NW3. This is end-of-tenancy cleaning in Belsize Park built for the flat you are actually leaving, a slice of a converted Victorian villa or a unit in a 1930s mansion block. We run it to the standard the inventory clerk will sign off, backed by a 48-hour re-clean guarantee. Ring 0333 555 2076 for a fixed price in about three minutes.
Last updated May 2026. Belsize Park sits in postcode NW3, on the slope below Hampstead in the London Borough of Camden, with the small print of NW3 4EX on streets near the station. This page is part of the Camden end-of-tenancy directory at End of Tenancy Cleaning London.
Your flat is one slice of someone else’s villa
Start with what you are renting, because it decides what the clean has to cover. The grand Italianate houses on Belsize Park, Belsize Park Gardens, Belsize Square and Lambolle Road went up as single family villas. The developer was Charles James Palmer, the builders Daniel Tidey and William Willett, and the land came off the old Eton College estate. Hardly any survived as houses. Most were split into flats between the wars and after. So the typical let here is one floor, or part of one, inside a building that several other households also live in.
That changes the inventory. A whole-house tenancy has a tidy boundary: everything inside the front door is yours to return clean. A converted-villa flat does not. Your demised space stops at your own front door, but the check-in report you signed almost certainly photographed the shared hall and communal stair, and listed them as part of the condition you took on. So the clean has a line running through it, and where that line sits is the first thing we work out on a Belsize Park job.
Then there is the other big housing type here. After the First World War, builders put up purpose-built mansion blocks around Haverstock Hill, red brick and stone, four or five storeys, with a shared entrance and a managing agent. Both types, the villa conversion and the mansion block, have one thing in common that a new-build does not. Old surfaces. Lime plaster, run cornice, timber sash windows, original boards, and a check-in report that photographed all of it.
Your demised space stops at your own front door, but the check-in report you signed almost certainly photographed the shared hall and communal stair, and listed them as part of the condition you took on.
The managing agent and the service-charge block
Here is what catches people out in Belsize Park. In a converted villa or a mansion block, your landlord is rarely the only party with a view on how you leave the place. There is usually a freeholder, a managing agent for the building, a service charge that pays for cleaning the communal parts, and a letting agent who handled your tenancy. That is more eyes on the check-out than a self-managed house ever has.
The managing agent matters because the communal hall and stair are cleaned on a contract paid for out of everyone’s service charge. The building has a written standard for those shared parts, and your inventory was taken against it. Scuff the communal stair carrying boxes down on moving day, and that mark sits in a space the freeholder maintains to a set standard, which is the kind of thing that gets noticed and billed. We have seen deductions argued over a communal hall more than once, because the tenant assumed the shared parts were not their problem.
Belsize Park also has a high share of lets handled by professional letting agents rather than private landlords, the offices clustered around Haverstock Hill and England’s Lane. A professional agent runs a proper check-in and check-out, briefs an inventory clerk to the move-in standard, and does not wave things through. The flip side is that a professional agent argues from a document, so if your clean matches the document you are on firm ground. We are on the books of 300+ letting agents, and the 57-point checklist we work to was built from what their clerks actually mark down, which is the same thing said two ways.
One more layer applies to shared flats. Camden runs a borough-wide additional licensing scheme for houses in multiple occupation, the third such scheme, which came into force on 8 December 2025 and runs to December 2030. It now reaches multi-occupied flats in blocks of three or more flats, exactly the mansion-block sharer let this area has plenty of. A licensed flat is held to a written standard, so the agent or managing agent who holds the licence inspects the check-out closely. If you are leaving a share, say so on the call.
Where the inventory draws the line in a shared building
This is the part that is genuinely different from cleaning a house. In a converted villa or a mansion block, the inventory draws a line between the parts that are yours to return and the parts that are shared. The deduction risk lives on both sides of that line, in different ways.
Inside your own front door, the rule is simple. Everything is yours, and it all gets cleaned to the check-in standard. The communal side is where judgement comes in. Say the check-in report photographed the shared hall and noted it clean. Then damage or mess you added on the way out is fair game for a deduction, even though the space is not yours to live in. We photograph the demised parts clearly, against the line the inventory draws, so there is no argument later about which marks were there before.
Conversions throw up physical problems too. The kitchen and bathroom in a villa flat were often squeezed into what used to be a bedroom or a return at the back. Pipework runs are long and old, so limescale builds badly. A mansion-block flat is usually more regular in layout, but the kitchens and bathrooms are frequently original in their bones and need a proper descale rather than a wipe.
So a Belsize Park clean is rarely just the rooms. It is the rooms, plus the shared parts the inventory caught, plus a kitchen and bathroom that an older conversion makes harder than the floor area suggests. We plan it that way from the booking call.
The conservation area, the sash windows and the hard water
Camden made the Belsize Conservation Area in 1979, because the stucco villas show consistent period detail and the council wanted that look kept. The conservation status is not paperwork you deal with as a tenant, but it tells you what the building is made of, and the building is what you clean.
Sash windows are the headline. The villas and the older mansion blocks have timber sash windows in boxes, and a check-in report photographs them inside: the glass, the frame, the sash box, the catch furniture. Over a tenancy the runners gather grime and the boxes gather dust, and a quick wipe of the glass leaves the parts a clerk actually checks. The conservation area means these windows tend to be kept original rather than swapped for sealed units, so the clean has more to it than a modern flat would.
The water is the other thing. North London is hard-water territory, so limescale builds into taps, showerheads and grout, and a long Belsize Park tenancy bakes it in. A calcium ring round a tap photographs badly against a check-in shot of clean chrome, and it is the single most common bathroom deduction we see here. Descaling is slow work, and it is most of the bathroom job on an older flat.
The churn around the Northern line, and why timing is tight
Belsize Park station opened on 22 June 1907, on the Edgware branch of the Northern line between Hampstead and Chalk Farm, at the top of Haverstock Hill. Leslie Green designed it in his ox-blood faience, and it is the one Green station with a forecourt of its own, which is why it picked up a Grade II listing in July 2011. None of that cleans a flat. But the station explains the market, and the market explains the timing.
A quick tube into the West End and the City makes Belsize Park a high-churn let area. It is full of professionals on one and two year tenancies, with a steady corporate flow through the mansion flats. Tenancies turn over often, agents line the next tenant up fast, and a flat that empties on a Friday is often re-let for the weekend. The clean has to land in that gap, after the flat is empty and before the inventory clerk arrives, and on a back-to-back let the window can be a single afternoon. Book early. We would rather hold a slot you confirm than scramble a team for a same-day job in a borough where the next tenant is already booked in.
Underneath all this, oddly, there is a second Belsize Park. A deep-level air-raid shelter runs below the station, built during the Blitz, its northern entrance behind 210 Haverstock Hill by the florist. Thousands of bunks were once allocated to named people, and the tunnels are now full of stored boxes. It has nothing to do with your deposit. It is just the kind of fact that reminds you this is a real place, not a row of identical addresses.
The report written before you unpacked
Most tenants in Belsize Park never think about the check-in report until the deposit comes back short. When you moved in, before your furniture arrived, a clerk walked the flat with a camera and wrote an inventory. The condition and cleanliness of every room, with dated photographs, and on a shared building the communal parts too. On a let at NW3 rents that report is detailed, and it almost always records that the flat was professionally cleaned at the start. That line sets the bar. At the end you are not asked to leave the flat clean in a general sense. You are asked to return it to the cleanliness in those photographs.
Read your own check-in report before you book anything. It tells you exactly what the check-out clerk will look at, because the same firm usually does both visits and works down the same document. If it recorded the oven clean, the door comes open and the glass gets split if it is double-glazed. If it recorded the windows clean inside, the sash boxes and runners are in scope. If the communal hall was clean and unmarked at check-in, your moving-day scuffs are yours. The report is the script for the argument you are about to have, and most tenants arrive without having read it.
That is why a cheap two-hour clean is a false economy here. The deposit at risk is measured in thousands. The difference between a clean that matches the report and one that nearly matches it is the difference between the whole deposit back and a deduction that dwarfs what the clean cost. The 57-point checklist exists for that reason. It is built backwards from what inventory clerks in this part of London actually mark, so the clean answers the document rather than a vague idea of tidy.
What the deposit rules actually say
A handful of rules decide how this plays out, and it helps to be plain about them rather than vague.
- Deposit protection
- Your deposit must sit in a government-approved scheme, and you must get the prescribed information within 30 days of paying it. The three schemes for England are the Deposit Protection Service, MyDeposits and the Tenancy Deposit Scheme, as set out on the government tenancy deposit page. If there is a dispute, the scheme runs a free adjudication, and the adjudicator never visits the flat. They read the reports, the photos and the invoices, and decide on paper.
- Professional cleaning is not compulsory
- A landlord cannot make you pay for a professional clean as a condition of the tenancy. Shelter is blunt: you only need to clean to the standard recorded when you moved in, and a clause forcing professional cleaning is not enforceable, as their guidance on cleaning deductions explains. The rules do not force a landlord to ignore a dirty flat, though. They can still hold back deposit money to put cleaning right if the flat goes back worse than the check-in record.
- Fair wear and tear
- A landlord cannot take money for reasonable wear and tear, the gradual ageing of paint, carpet and fittings, as Citizens Advice spells out in its guide to getting your deposit back. Cleaning is not wear and tear. It is the cleanable that was left undone, which is exactly the part a check-out clean removes from the argument.
- The Renters’ Rights Act 2025
- The bigger reform of the private rented sector, the Renters’ Rights Act 2025, changes a great deal about tenancies, but it does not change the basic deposit logic above. Your deposit is still measured against the inventory, and a clean that matches the check-in record is still the thing that keeps it whole.
None of this is exotic. It is the ordinary machinery of a private tenancy, and it all points one way. The tenant who can show the flat went back to the check-in standard keeps the deposit. The one who cannot, does not.
The 57 things we go through, room by room
The 57-point checklist is not a marketing number. It is the list of places a check-out clerk in this part of London actually puts their hands and their camera, grouped by room. Here is the shape of it on a Belsize Park flat.
Kitchen. The oven is the single biggest deduction in the borough, so it gets the most time. Both panes of a double-glazed door come apart so the brown film between them goes, the racks and runners are degreased, and the fan housing gets done as well as the base. The extractor filter is pulled and soaked, because clerks check it and tenants almost never do. Hob, splashback, the gap the cooker slides into, the sides of the units, the tops of the wall cabinets where grease sets hard. Inside and behind the fridge once it is defrosted, the washing-machine drawer and the rubber seal where black mould sits. Limescale off the taps and sink, because the water here is hard. In a villa conversion the kitchen is often a small room with a long pipe run, so it takes longer than its size suggests.
Bathrooms. Descaling is the whole game on an older flat with original pipework. Over a long tenancy limescale builds into the grout, around the taps, on the showerhead and along the glass in a way a quick wipe will not shift. Glass screen, tile grout, the sealant line along the bath and basin, behind the loo and the cistern, the extractor vent, the showerhead soaked until the jets run clear. Mansion flats sometimes have a second bathroom or an ensuite, usually the one a rushed clean skips, so it gets the same descale as the main one. Chrome polished until it matches the check-in photo.
Reception and bedrooms. This is where the height of these villa rooms bites. Cornice, ceiling rose, picture rail and the tops of the door frames carry dust three to four metres up that nobody sees from the floor and the clerk checks for first. Skirtings cleaned on the top edge as well as the face. Inside the sash boxes and runners, the glass where access allows, sills and catch furniture. Sockets and switch plates wiped, internal doors and frames, light fittings, radiators including the back, any cast fireplace kept as a feature. Floors finished to suit what they are, stripped boards, original boards or carpet, each treated the way the inventory expects.
Halls, stairs and the shared parts. In a conversion or a mansion block this is where the arguments happen, so the demised and communal parts get cleaned and photographed clearly against the line the inventory draws. The communal stair the freeholder maintains is checked for moving-day marks, and your own hall is returned to the check-in standard.
Every booking carries a 48-hour re-clean guarantee. If the inventory clerk or the agent challenges any item within 48 hours of the clean, we come back and put it right at no charge, judged against the check-out report rather than opinion. That is also why the first-time pass rate sits around 97%: the list comes from real check-out reports, so very little bounces, and what does is fixed fast. Over the years that approach has helped tenants recover £1.2m in deposit money that would otherwise have gone on cleaning deductions. That is the only number on this page that really matters to the person reading it.
What it costs, set against the deposit
We price a Belsize Park end-of-tenancy clean by the property, not by a vague hourly promise. Size, number of bathrooms, the state it is in, and whether carpets or internal windows are in scope all set the figure. You get it as a fixed quote on the phone before anyone is booked. No surprise top-ups on the day.
The sum that matters is the one almost nobody does in time. A clean of a one or two bed conversion flat here is a couple of hundred pounds in the usual range for this work. A larger mansion flat with two bathrooms, or a sharer let, is more, because it is genuinely more hours. Set either figure against the deposit. With one-bed rents in Belsize Park running from roughly £1,800 to £2,450 a month, the deposit held in a scheme is a four-figure sum. A cleaning deduction does not stop at the cost of the cleaning either. Clerks and agents commonly bill at a managed rate plus the inconvenience, and you are arguing it after you have moved out and lost access.
So the cheapest quote is rarely the rational choice here. The job either matches a detailed inventory or it does not. A clean that costs a little less and only nearly matches leaves the deduction fully in play.
A Belsize Square job from April
A second-floor flat in a converted villa on Belsize Square, end of an eighteen-month let, check-out fixed for the Friday because the agent had the next tenant moving in over the weekend. The check-in report was thick: professionally cleaned at the start, every sash window photographed, the oven recorded as clean, and the communal hall and stair listed and noted clean.
Two problems on arrival. The kitchen had been squeezed into a back return years ago, with a long pipe run, limescale thick on the hard-water taps and grease on the wall-cabinet tops. And the communal stair down to the front door had picked up scuffs on moving day, in a space the building’s managing agent keeps clean on the service charge. We had clocked the shared parts on the booking call, so we cleaned the demised flat to the check-in standard and put the communal stair marks right before the clerk arrived. The oven door came apart for the film between the panes, and the sash boxes were done as well as the glass.
The clerk did the check-out on the Friday with the check-in report open beside her. She went to the windows first, then the oven door glass, then the communal hall that tenants assume is not their problem. No cleaning deduction. The deposit, several weeks of a high Belsize Park rent, came back in full. The clean cost a fraction of one week of that deposit. That is the trade this whole page is about.
The clean cost a fraction of one week of that deposit. That is the trade this whole page is about.
Booking it around the check-out date
Booking is a phone call. Ring 0333 555 2076 and tell us the street, the rough size and how many bathrooms. Say whether carpets or internal windows are in, and whether the flat is in a converted house or a mansion block with shared parts. You get a fixed price on that call.
Timing is the thing to get right in Belsize Park, because these moves are usually tied to a fixed check-out slot or a new tenant arriving the same weekend. Book it as soon as you know the check-out date, not the night before. Same-day is a gamble in a high-churn area like this, where the agent has the next tenant lined up.
Tell us if the property is unfurnished or still part-furnished at clean time, whether the fridge can be defrosted the night before, and who holds the keys, the agent or you. Empty flat, defrosted fridge, keys sorted, shared parts flagged. Get those four right and the clean runs to time.
Nearby NW3 streets, and the work people add on
We cover the rest of NW3 too. The streets around Belsize Park are the same terms. Hampstead is up the hill on the same Northern line branch, all period houses and mansion flats. Chalk Farm is the next stop down toward Camden, Primrose Hill sits just to the south with its painted terraces, and Swiss Cottage is over to the west where the big converted houses meet the post-war blocks. Gospel Oak and South Hampstead run off the edges, and Kentish Town is the busier neighbour to the east. If your move crosses one of those lines, it is the same job and the same checklist.
The wider borough sits in the London end-of-tenancy directory, which lists every Camden area we cover.
Most check-outs need more than a clean, and people usually add these in the same booking so it is one visit on one date. Carpet cleaning on a let with carpets, since the inventory photographed them at check-in and a hot-water extraction is what brings them back. A separate oven clean where the kitchen is the only real problem. Internal and external window cleaning for the sash glass and boxes, which matters here because the report photographs windows specifically. Upholstery cleaning on a furnished flat where the sofas are on the inventory. Hard floor cleaning for the stripped boards these villas are full of. If the move itself is still to sort, our removals side can take it too, worth having one firm coordinate when there is a shared stair and a tight re-let weekend. People staying in the area rather than leaving tend to switch to a regular domestic clean or book a one-off deep clean instead, and the move-out service sits on the end-of-tenancy hub. You can check rough costs on our prices page, and if there is anything unusual about the flat, just say so when you get in touch.
Questions people ask
Do I have to clean the communal hall and stairs when I leave a flat in Belsize Park?
You clean them to the standard your check-in report recorded. In a converted villa or a mansion block the shared hall and stair are maintained by the freeholder or managing agent on the service charge, so day-to-day they are not your job. But if the check-in inventory photographed them clean and unmarked, any damage or mess you add on moving day, such as scuffs from carrying boxes down, can be deducted from your deposit. We clean and photograph the demised and communal parts against the line the inventory draws, so there is no argument about which marks were already there.
Why is cleaning a converted-villa flat different from cleaning a house?
Because the inventory draws a line between your demised space and the shared parts, and the building is old. Inside your own front door everything is yours to return to the check-in standard. The kitchen and bathroom in a villa flat were often squeezed into a back room, so pipe runs are long and limescale builds badly. The ceilings are the original villa height, with cornice and picture rails that gather dust a clerk checks first. A mansion-block flat is more regular but usually has original kitchens and bathrooms that need a proper descale rather than a wipe.
Can my landlord in Belsize Park make me pay for a professional clean?
Not as a condition of the tenancy. The rules stopped landlords and agents requiring a paid professional clean or writing one into the contract as a compulsory charge. Shelter is clear that you only need to clean to the standard recorded at move-in. What a landlord can still do is hold back deposit money to pay for cleaning if the flat is returned worse than the check-in report shows. So the clean is not legally compulsory, but a flat that does not match the inventory still costs you the deduction.
How much does end-of-tenancy cleaning cost in Belsize Park?
It is priced by the property, not by the hour, and you get a fixed quote on the phone before anything is booked. A one or two bed conversion flat is in the usual range for this work; a larger mansion flat with two bathrooms or a sharer let is more because it is genuinely more hours. Set either figure against the deposit, which on one-bed rents of roughly £1,800 to £2,450 a month is a four-figure sum, and the clean is the small side of the trade.
Does Camden licensing affect cleaning a shared flat in Belsize Park?
Indirectly, yes. Camden runs a borough-wide additional HMO licensing scheme, the third one, in force from 8 December 2025 to December 2030, and it now reaches multi-occupied flats in blocks of three or more flats. A licensed flat is held to a written standard, so the agent or managing agent who holds the licence tends to inspect the check-out closely. On a shared let we give the communal kitchen and bathrooms the most time and document each room separately, because sharers often have their own room inventories and deposits.
Do you guarantee the work if the inventory clerk is not happy?
Yes. Every booking carries a 48-hour re-clean guarantee. If the inventory clerk or the agent challenges any item within 48 hours of the clean, we come back and put it right at no charge, judged against the check-out report rather than against opinion. The first-time pass rate sits around 97 per cent, so it rarely comes to that, but the guarantee is there when it does.
Get a price
If you are leaving a flat in Belsize Park, the deposit riding on it is large and the inventory it is measured against is detailed, communal parts and all. A clean built backwards from that document is the difference between the whole deposit back and a deduction that costs many times what the clean did.
Ring 0333 555 2076 with the street, the size and your check-out date. Fixed price in about three minutes, a 57-point checklist on the day, dated photos for every room, and a 48-hour re-clean guarantee against the check-out report. That is the whole thing.
