In a Northwood Hills bathroom the inventory clerk goes to the shower screen before anything else, holds it up to the window, and looks for the chalky bloom the hard water leaves on glass within a fortnight of the last clean. That one surface decides more deposits up here than the oven does.
So this is what an end-of-tenancy clean in HA6 has to be built around: the check-out report, the chalk in the water, and the 1930s fittings that hide dust where a sponge never goes. We are Monster Cleaning Ltd, a domestic firm trading since 2014, and we clean these hand-backs to the agent’s list at a fixed price by bedroom count, with a 48-hour re-clean guarantee. Ring 0333 555 2076 for a price.
Last updated June 2026. We cover the whole of Northwood Hills, HA6: the parade and flats on Joel Street, the residential roads off Pinner Road, and the family-house streets running back toward Haste Hill and the edge of Ruislip Woods. This page sits inside the borough directory at End of Tenancy Cleaning Hillingdon.

The report written on your first day is the standard you are held to on your last. Match it, keep the dated photos, and the deposit conversation is short.
- When you moved in, a clerk walked the property and wrote a check-in inventory describing every surface, almost always with photographs, usually with the word “clean” against the kitchen and bathroom because the place had just been done professionally.
- At the end a clerk walks it again and compares the two reports line by line.
- Anything materially worse than the check-in entry, past fair wear and tear, can be charged against your deposit.
The adjudicator never visits. They read the inventory, the check-out report and the photos, and they decide on paper. Better evidence wins, every time.
Your deposit is sitting in one of the three government-backed schemes, the Tenancy Deposit Scheme, mydeposits or the DPS, and the agent has to account for it. That is why the check-out is genuinely adversarial rather than a wave-through: the clerk is paid to find faults.
That is not unfair. It just means you turn up with a clean that matches the in-going photographs and the paperwork to prove it, not optimism.
In a Northwood Hills house the faults point at the same short list nearly every time, because the houses are nearly all the same age and on the same water:
- the shower screen and the taps
- the oven and the hood over it
- the original picture rails and the deep airing cupboard on the landing
- the floors in the traffic lanes
Different street, different family, the same six photographs in the check-out report.
The chalk in the water, and what it does to an HA6 bathroom
Northwood Hills sits in the Affinity Water supply, drawn off the chalk under the Chilterns, and it runs hard to very hard. That single fact loses more deposits here than anything except a neglected oven.
A bathroom that looked fine to you grows all of this inside a fortnight of the last proper clean:
- a dull film on the shower glass
- a ring round the bath
- a crust on the taps
Clerks in HA6 photograph it on the way in and on the way out because they see it on every job.
A cloth does nothing to mineral scale that has set into chrome over a tenancy. It has to be broken down with a proper descaler, worked off, and the chrome brought back to a finish that reads against the check-in shot. In the bathroom:
- The shower screen is the item that gets held to the light first, so it comes back genuinely clear, with the scale lifted off rather than smeared over.
- Showerheads and hoses are descaled to the metal.
- Tile grout is scrubbed back.
- Any mould is lifted from the sealant lines along the bath.
Where the limescale has eaten into the chrome past the point a clean can fix, we photograph it before we start so a clerk cannot bill you for wear that was there at check-in.
The shower screen decides more deposits up here than the oven does.
The kitchen, the other heavy room
The oven is where clerks reach first, because grease is unarguable in a photograph. We clean it by hand rather than wipe it:
- racks out, soaked and degreased
- the door glass opened where the model allows so the brown film between the panes comes out
- the cavity scraped back
- the extractor hood and its metal filter degreased
The hob and knobs come back to a clean finish, and the cooker is pulled out where it moves so the wall and floor behind it are done too, the same around the washing machine and the fridge.
Sink, taps and tiled returns get the same descaling the bathroom does, because the water does not give the kitchen a miss either.
A suburb built in one go: what 1933 left behind to clean
Northwood Hills was open ground until the Metropolitan Railway dropped a station here on 13 November 1933, and almost every house you can rent in HA6 went up in the twenty years after that. That stock decides the clean.
It is its own place, not Northwood proper up the hill and not Pinner down the other side:
- large 1930s semis and detached houses with gardens
- a parade of shops on Joel Street
- Northwood Hills Circus, where the buses stop
The pub on the corner, the Northwood Hills Hotel across the road from the station, is where a teenage Reg Dwight, later Elton John, played piano for a pound a night in the mid-1960s. None of that is decoration here. It tells you exactly what the stock is.
One clean covers the whole property top to bottom, inside and out of every fitting, against the inventory. That is what end of tenancy means, and it is a different job from a deep clean you book to keep living somewhere or a regular tidy that keeps an occupied home ticking over.
Where an interwar house hides the work
Because the houses up here are interwar, the work concentrates in places a tenant clean never reaches.
- Rails, door tops, skirtings and coving
- The picture rails, the tops of doors and frames, the deep skirtings and any coving hold a grey line the check-in camera caught clean and the check-out camera will catch dirty, so all of it is dusted down by hand.
- The airing cupboard
- The built-in airing cupboard on the landing, with the cylinder in it, is a classic dust trap, and the clerk opens it with a torch, slats and all, so we clean it knowing they will.
- Wardrobes
- Fitted and built-in wardrobes are done inside and out, runners included.
- Floors
- The last of the recurring six. The flats over the parade carry fitted carpet that holds the wear of the walkways, and the houses often have laid floors gone grey in the lanes where everyone walks.
The check-in report photographs floors in detail because they are expensive items and a clear before-and-after is easy for an adjudicator to read. So carpets are vacuumed thoroughly including the edges and under what moves, and hard floors are washed with the right product for the material.
Across the rest of the property:
- the inside of every window cleaned, with frames, sills and reveals
- every internal door done on both faces, with the top edge and handles
- the stairs and the full run of the banister and spindles dusted and wiped
- cobwebs off the ceiling corners
- switches, sockets and radiators cleaned in and behind
Any carpet shampoo or extra oven work is folded into the same visit rather than booked as a second trip.
Who books us up here
The work mix splits two ways. Most of it is private tenants moving out of let semis and flats, with a steady run of cleans booked by the landlords and the agents along the parade.
There is a fair amount of shared-house and professional-let work too, because the houses are large and the area is a straight run into central London on the Metropolitan line, which is exactly the stock the new licensing scheme below has in its sights.
We do the converted flats over the shops as well as the houses, including the communal-facing entrance the inventory sometimes asks for on a flat.
What it costs, and the sums nobody runs until the report lands
Pricing is flat and given before we start, with no separate call-out or materials line added afterwards. The four-bed is the most common size up here, because the streets off Pinner Road are full of family semis.
| Property | Typical duration | Estimated cost |
|---|---|---|
| Studio flat | 3 to 4 hours, 1 cleaner | From £156 |
| 1-bed flat or house | 4 to 5 hours, 2 cleaners | From £207 |
| 2-bed flat or house | 5 to 6 hours, 2 cleaners | From £243 |
| 3-bed house | 6 to 8 hours, 2 cleaners | From £339 |
| 4-bed house off Pinner Road | Full day, 2 to 3 cleaners | From £425 |
- By the hour
- If you would rather pay by time for a part-clean or a top-up than a full hand-back, that is £30 per cleaner per hour. For a let property going through a check-out we would always steer you to the fixed price, because that is the version the checklist and the guarantee attach to.
- Oven with the clean
- The oven deep-clean is a £31 add-on to the end-of-tenancy price.
- Oven on its own
- Before a check-out it is £77 for a single oven, £110 for a double, and £143 for a 90cm range. The range cookers in the extended kitchens up here usually fall in that last band.
- Carpet shampoo
- Done on a hot-water extraction machine, and worth taking on a flat over the parade or any let where the carpets carried years of footfall: £29 per bedroom, £36 for a living room, or £94 for the whole carpeted area of a typical two-bed.
Those figures assume a property in normal lived-in shape. These take longer, and we say so on the phone rather than after:
- a long tenancy with heavy wear
- a pet household
- somewhere that has not had a deep clean in years
Run the sums the way the deposit makes you. A three-bed at £339 against a deposit of several thousand pounds is not really a decision, and most tenants only do that arithmetic after they have tried, failed the check-out and lost the first round.
Over the years our work has helped tenants and landlords recover more than £1.2m in deposits that would otherwise have gone on cleaning deductions.
People mix up three different jobs and book the wrong one, so it is worth being plain about which is which.
- Check-in inventory
- The report a clerk writes on day one describing every surface, with photos. It is the benchmark your check-out is judged against, which is why we clean to it and not to a vague idea of clean.
- End-of-tenancy clean
- Built to pass that inventory and get the deposit signed off, with the property empty, against the agent’s checklist, with the 48-hour re-clean guarantee on it.
- Deep clean
- A reset of a home you are staying in, lived-in, furniture in place, measured against your own standard rather than a report.
- Regular clean
- Ongoing maintenance of an occupied home, a different job again, billed by the hour.
Every Northwood Hills booking runs to a 57-point agent-approved checklist that mirrors the route the inventory clerk walks, item for item. We hold accounts with 300+ letting agents across London and know most of the inventory formats in use, including the ones the Pinner and Northwood agencies run, Gibbs Gillespie and Gibson Honey among them.
What 1 May 2026 changed, and Hillingdon’s new HMO scheme
The Renters’ Rights Act 2025 went live on 1 May 2026. Here is the part people get wrong: the cleaning side of a move-out did not change at all.
- Section 21
- No-fault evictions are gone.
- Existing tenancies
- Every existing assured shorthold tenancy in England has converted to a periodic one.
- Notice
- A tenant can give two months’ notice at any point rather than waiting for a fixed term to end.
- Cleaning deductions
- A deduction for cleaning still has to be evidenced against the original inventory rather than simply asserted, exactly as before.
What changed is timing, and timing is what bites in a commuter suburb full of short professional lets, because move-outs get more frequent and far less predictable. The dull, paying takeaway is to book the clean earlier than you used to.
Hillingdon’s additional HMO licensing
The bigger local change is for landlords. The London Borough of Hillingdon has approved a borough-wide additional HMO licensing scheme.
- Approval
- The Cabinet signed it off on 19 February 2026.
- Applications
- Opened on 20 May 2026, and are to be in by 23 August.
- In force
- From 24 August 2026.
- Who it covers
- Smaller shared houses, let to three or four people and below the five-occupant mandatory threshold, come into licensing for the first time, with conditions on safety, property standards and management.
- Cost
- Licences run five years and cost £1,401 per property, payable in two parts of £934 and £467, with a ten per cent reduction for accredited landlords and managing agents.
The detail is on the Hillingdon Council additional licensing pages.
Why a cleaning firm is telling you this: the large 1930s semis off Pinner Road and around the parade are exactly the stock let as shared houses, so a lot of Northwood Hills landlords will be in scope for the first time.
A licensed HMO is inspected, and the management standard the council expects covers the condition a property is handed on in between tenancies. A documented professional clean between sharers is part of showing the place is run properly, and we invoice clearly for landlords and turn a void around fast so the next tenancy starts on time.
For tenants, the plain-English version of the deposit rules is on the gov.uk guidance, and Shelter’s tenancy deposit advice walks through a dispute step by step.
Booking it, and the one thing Northwood Hills makes easy
Booking is a phone call, and parking, the part that ruins move-out day in central Hillingdon, is easy up here.
- Ring 0333 555 2076 or email office@monstercleaning.com with the Northwood Hills address, the number of bedrooms, your check-out date, and whether you want carpets or the oven added. We give you a fixed price on the spot.
- Tell us the check-out date and time and we schedule the clean to finish with margin before the clerk arrives, ideally the day before. At quieter times we can often come within 48 hours; in the busy end-of-month weeks, give us a few days where you can.
- Empty and furniture-out is best, though we will work around a few remaining items if the move is still in progress.
Most roads up here are unrestricted and the houses generally have a driveway, so we get a van close to the door on nearly every job, which keeps the day moving and the cost down.
If the inventory clerk or the agent flags any of our cleaning on the check-out, the 48-hour re-clean guarantee means we come back and put it right within 48 hours of being told, at no extra charge, in writing on the booking.
You are not handed a refund and left to sort the cleaner yourself. We return, re-clean the flagged items, and take the point up with the agent directly, because we work to their list and we will stand behind it. In practice we are rarely called back.
Questions we get asked
How much is end of tenancy cleaning in Northwood Hills?
A studio is from £156, a one-bed flat or house from £207, a two-bed from £243, a three-bed house from £339 and a four-bed from £425. These are fixed prices given before we start, with no call-out or materials charge added afterwards.
Why does the bathroom matter so much up here?
Northwood Hills is on Affinity Water’s hard chalk supply. Scale builds on the shower screen, the taps and around the bath within a fortnight, and check-out clerks in HA6 photograph it every time. It has to be broken down with a proper descaler and worked off, not wiped, and the chrome brought back to match the check-in photos. The shower screen is the first thing held to the light.
Do you guarantee the clean will pass the check-out inventory?
Yes. We clean to a 57-point agent-approved checklist that mirrors the inventory clerk’s route. If the clerk or agent flags our cleaning, the 48-hour re-clean guarantee means we return within 48 hours at no charge and take the point up with the agent ourselves.
Is the oven included or charged separately?
The oven deep-clean is an add-on to the end-of-tenancy clean, from £31: racks, door glass, the cavity and the extractor filter. If you only want the oven done on its own before a check-out, that is £77 for a single, £110 for a double and £143 for a 90cm range cooker, which is the band most of the extended-kitchen ranges up here fall into.
Do you clean the original picture rails and the airing cupboard?
Yes, and these are exactly where the 1930s houses up here lose deposits. Picture rails, the tops of door frames, deep skirtings and the built-in airing cupboard on the landing are all dusted down by hand. The clerk opens that cupboard with a torch, so we clean it knowing they will.
How long does an end of tenancy clean take in a Northwood Hills semi?
A one or two-bed flat is usually a half to most of a day for a two-person team. A three or four-bed house off Pinner Road runs a full day, longer if the kitchen was extended and heavily used. We do not rush a job to fit a slot: it is finished against the checklist or it is not done.
Can you clean around a check-out appointment that is already booked?
Yes. Tell us the check-out date and time when you book and we schedule the clean to finish with enough margin before the clerk arrives, ideally the day before. Empty and furniture-out is best, but we will work around a few remaining items if the move is still in progress.
I am a landlord with a shared house. Does the new Hillingdon licensing scheme affect me?
Quite possibly. Hillingdon’s borough-wide additional HMO licensing scheme was approved on 19 February 2026, applications opened on 20 May 2026 and it comes into force on 24 August 2026, bringing shared houses let to three or four people into licensing. A licence runs five years and costs £1,401, with a ten per cent reduction for accredited landlords. A documented professional clean between tenancies supports the management standard the council expects, and we invoice clearly and turn voids around fast.
Does the Renters’ Rights Act 2025 change the clean?
No. From 1 May 2026 Section 21 is abolished and assured shorthold tenancies have converted to periodic ones, but a cleaning deduction still has to be evidenced against the original inventory exactly as before. The real effect is timing: move-outs are more frequent and less predictable, so book the clean earlier than you used to.
Do you cover the streets off Joel Street and Pinner Road?
Yes, the whole of Northwood Hills: the parade and the flats on Joel Street, the roads running back off Pinner Road, the family-house streets out toward Haste Hill and the edge of Ruislip Woods, anywhere in HA6 within reach of Northwood Hills station on the Metropolitan line. We do houses, flats, maisonettes and the converted flats over the parade, not commercial units.
What if I only need part of the property cleaned?
We can work by the hour at £30 per cleaner per hour for a part-clean or a top-up. For a full hand-back on a let property we would steer you to the fixed price instead, because that is the version the agent-approved checklist and the 48-hour re-clean guarantee attach to.
Are you an established company or a one-off operator?
Monster Cleaning Ltd has traded since 2014. We hold accounts with 300+ letting agents and have helped recover more than £1.2m in tenancy deposits for customers. Call 0333 555 2076 or email office@monstercleaning.com and we give a fixed price on the call.
