The hill where the boroughs meet
Stand at the top of Westow Hill, by the old crossroads where the Vicar’s Oak used to mark the parish lines, and you are standing on one of the few spots in London where four council areas brush up against each other. The diarist John Aubrey wrote in 1719 that this was the tree “where four Parishes meet at a point”. The modern version is messier. Upper Norwood and the wider Crystal Palace district sit across Croydon, Lambeth, Bromley and Southwark, with Lewisham a short walk down the far side of the park. Your postcode might read SE19, your taxonomy might say Bromley, and your actual front door might still be in Croydon.
That matters more than it sounds, and we will get to why.
We are Monster Cleaning, a domestic firm working since 2014, and end of tenancy is the bulk of what we do up here. For an SE19 flat the headline is simple: we clean the whole place against your check-in inventory, we price it by the size of the property rather than by the hour, and we back the work with a free re-clean if the clerk pushes back. A two-bedroom flat off Church Road runs to a fixed quote, agreed on the phone before we set a date, and the cleaners stay until the list is finished.
Upper Norwood is an odd patch to work, in a good way. The Triangle at the top, where Westow Hill meets Church Road and Westow Street, is all independent shops and cafes, the kind of high street where the Bookseller Crow has been selling books for decades and Blue Door Bicycles has been fixing bikes on Central Hill nearby. Below it the ground drops away into the park, with the boating lake, the maze and those famous dinosaurs. The flats sit on the slopes in between, on roads that wind down from the ridge, and the people moving in and out of them are exactly who we clean for: tenants on a two or three-year run in a converted villa, students sharing a big house near the station, families in a maisonette who are finally buying.
Which council actually licenses your let
This is the bit non-locals get wrong. Because Upper Norwood is split between councils, the licensing rules on your rental depend on exactly which side of the hill your flat sits, and the boundaries here are old and irregular.
The SE19 3 postcodes, the ones around the Triangle and Westow Hill, fall inside the London Borough of Croydon, in the Crystal Palace and Upper Norwood ward. So even though this page lives under Bromley in our site, a flat at the SE19 3AE end is almost certainly a Croydon address, and Croydon is where the rules are about to change.
From 1 September 2026 Croydon brings in two new property licensing schemes that run for five years. The one that catches most Upper Norwood lets is the additional HMO licensing scheme, which applies right across the borough. It covers smaller houses in multiple occupation that national rules miss, so a villa carved into shared rooms on the Croydon side will need a licence whether or not it hits the mandatory threshold. Croydon also adds selective licensing, but only in 14 of its 28 wards, places like South Norwood, Selhurst and Thornton Heath. Crystal Palace and Upper Norwood is not on that selective list, so a single household renting a self-contained flat here is not caught by selective licensing, though the borough-wide HMO rules still bite on shared houses.
Step a few streets the other way and the picture flips again. The slice of the hill that sits in Lambeth, out towards Gipsy Hill, has had selective licensing since September 2025 and runs additional HMO licensing borough-wide too. Bromley, the borough this page is filed under and the one that actually owns the park and the transmitter, has gone the other way: it runs only the mandatory HMO scheme, with no additional or selective licensing at all. A Bromley councillor put it plainly when residents asked for more, saying the council “cannot use HMO licensing to control where HMOs are situated”. Instead Bromley leans on an Article 4 planning direction from 2022 that forces new HMOs to seek planning permission.
So the honest answer to “do I need a licence” is: check your borough first.
For the standard mandatory rule, which applies everywhere, a property is a licensable large HMO when at least five tenants from more than one household share a kitchen, bathroom or toilet. Below that, the local scheme decides. None of this changes what an end of tenancy clean has to achieve, but it does change who your landlord answers to, and licensed lets tend to be inspected harder at check-out because the paperwork is already tighter.
One more thing is coming for every borough on the hill. The Renters’ Rights Act 2025 got Royal Assent in October 2025 and is rolling out through 2026. It scraps fixed-term assured shorthold tenancies and changes how landlords end a let, which means more mid-tenancy moves and more check-outs happening at odd points in the year rather than all at once each summer.
Your postcode might read SE19, your taxonomy might say Bromley, and your actual front door might still be in Croydon.
What the split villas need
The housing up here has a particular shape, and it changes the cleaning. Upper Norwood filled out after 1854, when the Crystal Palace was rebuilt on the ridge above Sydenham and the railways followed it up the hill. What the speculators put up were large, tall houses for the Victorian middle class, three and four storeys, big bay windows, deep cornices and the long staircases that came with that kind of money. The palace itself burned down one night in 1936, but the villas stayed, and so did the dinosaurs Benjamin Waterhouse Hawkins built down in the park in 1854, which are still standing on their islands at the bottom of the hill.
Most of those big houses are now flats.
A grand villa on Auckland Road or Fox Hill that once held one family is now three or four separate lets, and the conversion is where the cleaning gets fiddly. Original fireplaces still sit in the bedrooms, soot in the surrounds. Picture rails and deep skirting collect a kind of dust that a quick wipe never touches, and on a check-out the clerk runs a finger along them. Where the original windows survive they are heavy, painted over at the edges, and the runners hide grime that shows the moment one is slid open. We keep a soft cap on how much of that window work a single job carries, because plenty of these flats had the lot replaced with uPVC years ago, but where the old timber survives it takes real time to do properly.
The hill itself is the other thing. Upper Norwood is one of the highest points in south London, which is exactly why the transmitter went up here. The Crystal Palace mast, built in 1956 and standing around 220 metres, is the spike you can see from half of London, and the streets underneath it are steep. Carrying a vacuum, a box of kit and an extraction machine up to a top-floor flat on Beulah Hill is a proper workout, and there is rarely anywhere easy to park while you do it. So we plan for it. Our cleaners know which roads near the Triangle are permit-only during the day and which side streets off Church Road you can pull onto for an hour to load in and out. We would rather tell you straight that a job needs an early start than turn up at ten and lose the morning to a parking warden on Westow Hill.
Damp shows up too, the way it does in any old, tall property on an exposed ridge that catches the weather. North-facing bathrooms in these conversions grow black mould along the silicone and across the ceiling above the shower, and ground-floor flats in the bigger houses can smell of it. That is a cleaning problem at check-out, not just a maintenance one. It is also exactly the sort of thing the inventory photos from your move-in will be held up against, so it pays to deal with it rather than hope the clerk does not look up.
Kitchens in these flats are often a later addition, squeezed into what was once a back room or a return, with cheap units and a lot of awkward edges where grease gathers. They take longer than the square footage suggests. We mention it because people booking a one-bedroom expect the kitchen to be quick, and in a converted villa it rarely is.
The 57-point clean, room by room
Every end of tenancy job we run works off a 57-point agent-approved checklist. It is the same list the letting agents around the Triangle recognise, because we are on the books of 300+ letting agents and they have seen it. The cleaners bring it on paper and work down it room by room, so nothing gets skipped because someone was in a hurry to finish.
The kitchen takes the longest. Appliances come away from the wall where they can, so we reach the grease that builds up down the sides of a cooker. The oven gets stripped, the door glass split apart and cleaned on both faces, the racks soaked. Inside the fridge and freezer, behind the salad drawers, around the door seals. Cupboards emptied and wiped inside and out, including the tops where dust and cooking film settle. Tiles, splashbacks and the sink, with the limescale taken off the taps.
Bathrooms are about the same, just wetter. We scrub the grout, clear soap scum off the screen, take the limescale off the showerhead and taps, and get the toilet properly clean, hinges and base included. The extractor fan cover comes off if it lifts. Mirrors and any glass go streak-free.
Then the rest of the flat. Dusting from the cornices down, which on these high Victorian ceilings means a pole. Cobwebs out of the corners. Skirting boards, door frames, switches and sockets wiped. Internal glass and the inside of the windows cleaned, frames and sills included. Wardrobes, cupboards and drawers done inside and out. Floors vacuumed and washed or carpets vacuumed through. We finish on the things people forget, the radiators, the dust on top of the doors, the marks where furniture stood.
A few practical conditions before we come. The flat needs to be empty of your belongings, because we clean the property, not around your boxes. We need the electricity on and the hot water running. If there is a fridge or freezer to do, defrost it the night before, or it sits in a puddle and cannot be cleaned. We will run through all of this when you call, and we will tell you anything specific the job needs once we know the property.
The checklist is also what keeps two of our cleaners working the same flat to the same standard. One pair can take the kitchen and a bathroom while the other works through the bedrooms and the hall, and because both are ticking off the same 57 points, the flat ends up consistent rather than patchy. On a big top-floor let that is the difference between a half-day and a lost day.
What an SE19 clean costs
We price end of tenancy by the size of the property, not by the hour, so the number you are quoted is the number you pay and the cleaners stay until the list is done. A studio is £156. A one-bedroom flat, which is the common let in the converted villas around Church Road, is £207. A two-bedroom is £243. A three-bedroom is £339, and a four-bedroom is £425. Those are full prices, not teaser rates, and the quote is fixed on the phone once we know the flat.
If you would rather book cleaners by the hour for a smaller job, that is £30 per cleaner an hour, though for a check-out we usually steer people to the fixed end of tenancy price because it is the version that carries the guarantee.
The reason we can quote a flat rate and still hold a 97% first-time pass rate is volume. We have done a lot of these flats, we know how long a top-floor conversion on the hill actually takes, and we build that into the price rather than clock-watching on the day. Over the years that approach has helped tenants recover £1.2m in deposits that would otherwise have gone on cleaning deductions.
Carpets and ovens are priced separately when you want them done as a deep treatment, and the next section covers those.
Proving it to the inventory clerk
A deposit dispute is won or lost on evidence, and the evidence is the inventory. Whatever the clerk wrote at check-in is the standard you are held to at check-out, no higher.
That cuts both ways, and it is worth knowing the rule. Your landlord cannot insist you pay for professional cleaning as a condition of the tenancy. What they can require is that the flat is left as clean as the check-in report says it was. If the inventory recorded the oven as clean when you moved in, it needs to be clean when you leave. If it noted limescale on the taps from day one, you are not on the hook for that. Citizens Advice sets out the position and the evidence that wins, including check-in and check-out inventories, photos, and a receipt if you paid for a clean.
This is where booking a professional end of tenancy clean earns its money beyond the obvious. You get an invoice with our name on it, dated, for the property. If the clerk disputes a room, that receipt sits in your evidence bundle alongside the check-out photos, and it carries weight with an adjudicator because it shows the work was done to a known standard rather than rushed by a tenant on moving day.
The process for a disagreement is worth knowing before you are in one. If you and the landlord cannot agree on deductions, the deposit scheme runs a free dispute resolution service, and you usually have three months from moving out to put a claim in. An adjudicator reads the written evidence from both sides and decides, and the decision is final, so the quality of your evidence is everything. Photos of each room at check-out, your copy of the check-in inventory, and the cleaning invoice are the three things that win these. The Tenancy Deposit Scheme has reported that cleaning shows up in more than half of all the disputes it sees, which tells you where the money is lost.
If the clerk does challenge our work, the 48-hour re-clean guarantee is the backstop. Tell us within that window, send us the clerk’s note, and we come back and put right anything they have flagged, free. We would rather return and fix one room than have you lose a chunk of your deposit over it, and in practice it is rare, because the checklist catches most of what a clerk looks for before we leave the first time.
- Check-in inventory
- The report, usually with photos, that records the condition and cleanliness of the flat when you moved in. It is the benchmark your check-out is judged against, so dig out your copy before the clean.
- Deposit protection scheme
- Your deposit has to be held in one of three government-backed schemes, and the landlord has 30 days to protect it and tell you which. Shelter explains the rules and the free dispute resolution service that comes with it.
- Additional HMO licence
- A council licence for smaller shared houses that the national mandatory scheme does not cover. From September 2026 Croydon requires one borough-wide, so most shared lets on the Upper Norwood side of the hill will need it.
- End of tenancy clean
- A full, one-off clean of an empty property against the inventory, priced by property size. Different from a regular maintenance clean, which keeps a lived-in home ticking over and is not built to pass a check-out.
Add-ons the Triangle flats tend to need
The standard end of tenancy clean covers everything on the checklist, but two jobs often need a deeper, separate treatment, and a couple more come up on these particular flats. You book them alongside the main clean.
Carpets are the common one. The villa conversions tend to keep carpet in the bedrooms and on the stairs, and years of foot traffic up and down a hill flat leave a mark a vacuum will not shift. We use hot water extraction, which pushes heated solution into the pile and pulls the dirt back out, lifting ground-in grime and stains without soaking the carpet through. It is priced at £36 a bedroom, £43 for a living room, or £115 for a whole two-bedroom flat. You can read more on our carpet cleaning service.
Ovens are the other. A deep oven clean means taking the door apart, pulling out the removable parts and cleaning each one separately, so the baked-on grease comes off the places a wipe-round cannot reach. A single oven is £77, a double is £110, and a range cooker is £114. On a check-out the oven is one of the first things a clerk opens, so it is worth getting right.
Upholstery cleaning uses the same hot water extraction as the carpets, for sofas and chairs that came furnished with the let and need to match the inventory. And exterior windows, the bay sashes on these tall villas especially, we do with water-fed poles and purified water, which reaches the upper floors safely and dries without streaks. Tell us when you book which of these you want and we fold them into the one visit.
Booking and what we need from you
Booking is a phone call. Ring 0333 555 2076, tell us the flat, where it is on the hill, how many bedrooms and bathrooms, and whether you want carpets, the oven or anything else doing. We work that into a fixed quote there and then, and we book the date.
We clean seven days a week, weekends included, which matters in SE19 because tenancies here turn over on all sorts of days and the check-out is often booked for a Saturday. If you would rather email, we are at [email protected], and the company is run out of 255 Upper Richmond Road West, SW14 8QS.
Access tends to be the thing worth sorting early. Plenty of our Upper Norwood clients are not in the flat by the time we clean, because they have already moved out and the keys are with the agent down on Westow Hill or at Crystal Palace station. That is fine. Tell us on the call who holds the key and how we get it, and we work around it. The flats nearest the station, where the Overground and the Southern trains come in, are the easy ones for the cleaners to reach without a car. The ones higher up towards Beulah Hill and Gipsy Hill station, on the steep streets, are where we plan parking and timing more carefully.
Give us as much notice as you can, especially around the end of the month when everyone moves at once. We will tell you on the call roughly how long the job will take, when the cleaners will arrive, and what we need from you on the day, which comes back to the same short list: flat empty, electricity on, hot water running, fridge defrosted if it needs cleaning.
If the clerk flags anything afterwards, you have the 48-hour re-clean guarantee, and you call the same number. That is the whole process.
If you are moving within the wider area, we cover the neighbouring patches too. There is a separate page for end of tenancy cleaning across the rest of Bromley, and we work the streets either side of the park in Crystal Palace, down the hill in Penge, and over towards Gipsy Hill on the Lambeth side.
Questions Upper Norwood tenants ask
Which council does my Upper Norwood flat fall under?
It depends where on the hill you are. The SE19 3 postcodes around the Triangle and Westow Hill are in Croydon, in the Crystal Palace and Upper Norwood ward. Other parts of the district sit in Lambeth, Bromley or Southwark. Check your council tax bill if you are not sure, because it decides which licensing rules apply to the let.
Why is this page filed under Bromley if my address is in Croydon?
Bromley is the taxonomy term for this area on our site, and Bromley owns Crystal Palace Park and the transmitter. But the residential streets around the Triangle are mostly Croydon addresses. We clean across all the boroughs that meet on the hill, so the filing does not change anything about your booking.
Does my landlord need an HMO licence here?
If five or more tenants from more than one household share a kitchen or bathroom, yes, that is a mandatory large HMO anywhere. For smaller shared houses it depends on the borough. From 1 September 2026 Croydon requires an additional HMO licence borough-wide, and Lambeth already runs one, so most shared lets on the Upper Norwood side will need a licence.
How much does an end of tenancy clean cost in SE19?
It is priced by property size, not by the hour. A studio is £156, a one-bedroom flat is £207, a two-bedroom is £243, a three-bedroom is £339 and a four-bedroom is £425. We fix the quote on the phone once we know the flat, and the price is what you pay.
Do you charge by the hour instead?
We can, at £30 per cleaner an hour, for smaller jobs. For a check-out we usually recommend the fixed end of tenancy price, because that is the option that comes with the 48-hour re-clean guarantee.
What is the 48-hour re-clean guarantee?
If the inventory clerk or your agent challenges our work, you tell us within 48 hours of the clean, send us their note, and we come back to put right whatever they flagged at no extra cost. It is there so a single disputed room does not cost you part of your deposit.
Will a clean actually get my deposit back?
Cleaning is the most common cause of deposit deductions, so a clean done to the check-in standard removes the usual reason a landlord withholds money. We also give you a dated invoice, which sits in your evidence if there is a dispute. We have helped tenants recover £1.2m in deposits that would otherwise have gone on cleaning.
Can my landlord force me to pay for professional cleaning?
No. A landlord cannot make professional cleaning a condition of the tenancy. They can require the flat to be left as clean as the check-in inventory recorded it. Booking a clean is your choice, and most tenants do it because it is the simplest way to meet that standard.
What standard do you clean to?
We clean against your check-in inventory, working off a 57-point agent-approved checklist room by room. That is the standard letting agents and inventory clerks across south London recognise, and it is why we hold a 97% first-time pass rate.
Do you clean the big split villas on the hill?
Yes, they are most of our work up here. The tall houses divided into flats have high ceilings, deep cornices and heavy windows that take longer, and we plan the time and the kit for it, including the steep streets and tight parking near the Triangle. Top-floor flats with the original staircases are the slowest, and we price that in.
Can you clean the carpets and oven at the same time?
Yes. Both are separate deep treatments you book alongside the main clean, on the same visit. Carpets are from £36 a bedroom and a single oven is £77, with a double at £110 and a range at £114.
Do I need to be there during the clean?
You do not have to be, as long as we can get in and the flat is ready. The property needs to be empty of belongings, with the electricity on, the hot water running, and the fridge defrosted if it needs doing. Many tenants hand us a key or arrange access through the agent.
Do you work weekends?
Yes, seven days a week including weekends. Check-outs in SE19 land on all sorts of days, and Saturday is a common one, so weekend slots are part of the normal rota.
How far ahead should I book?
As far ahead as you can, particularly at the end of the month when everyone moves together. A few days’ notice is usually fine off-peak, but month-end Saturdays go quickly, so call sooner if your check-out date is fixed.
How do I book?
Call 0333 555 2076 with the flat size, the location and any extras you want, and we quote and book on the call. You can also email [email protected]. We are based at 255 Upper Richmond Road West, SW14 8QS.
