On a brand-new flat at Grange Farm Close, the first thing the check-out clerk reaches for is the heat-recovery vent in the ceiling, because the white louvres go grey with dust inside a year and nobody living there ever thinks to wipe them.
Monster Cleaning Ltd has been the move-out crew for South Harrow tenants since 2014, and on the regenerated estate we clean to the standard the clerk is actually marking against, room by room, at a fixed price by bedroom count, with a 48-hour re-clean guarantee tied to the check-out report itself. Ring 0333 555 2076 and you have a fixed price in a couple of minutes.

Grange Farm is really two places at once.
- The old estate
- 282 prefabricated homes thrown up in the late 1960s, three identical three-storey clusters sitting between Northolt Road and Shaftesbury Avenue. Most of it is gone now.
- The new estate
- In its place Harrow Council is building roughly 500 new homes in phases. Phase 1 finished in autumn 2023: 89 homes, 69 for council and affordable tenants and 20 on shared ownership, built by Higgins.
So when a let comes up here today, it is nearly always one of those Phase 1 flats. The move-out clean has to suit a flat the developer handed over barely two years ago, not a tired old maisonette.
That changes what the inventory check is looking for. A clerk walking a 2023 flat is comparing it against a hand-over pack full of the word “new”, and the flat itself is built differently:
- the kitchens are handle-less
- engineered timber runs across the open-plan kitchen and living space, with tile in the wet rooms
- heating and hot water come off a heat-interface unit tucked in a hall cupboard
- there are mechanical heat-recovery grilles in most rooms
None of that existed on the prefabs, and all of it carries its own way of getting dirty and its own way of being judged.
The demolition has moved on too. Phase 2A came down in March 2026, clearing the ground for another 45 affordable homes, up to 36 of them council homes for secure tenants still on the estate. Wates is the council’s partner for the later phases.
Building starts in the spring, with people due to move in by the summer of 2027, so for the next while there is a working site fence on part of the estate and the access changes month to month. We plan around it on the day.
What 2 May 2026 changed for South Harrow landlords
Two separate things landed this year, and people muddle them.
The first is national
The Renters’ Rights Act 2025 went live on 1 May 2026.
- Section 21 no-fault evictions are gone.
- Every assured shorthold tenancy has rolled over to a periodic one, so a tenant can give two months’ notice whenever they like.
What it did not touch is the clean:
- the check-in benchmark still applies
- the deposit still has to come back inside ten days of an agreed figure
- the agent still has to evidence any deduction
The effect here is timing, not the work: move-outs get less predictable, so the slot you want goes sooner.
The second is local
This one matters if you are a private landlord rather than a council tenant. Harrow designated six new selective licensing schemes on 2 February 2026, and the one covering Roxeth ward, which takes in South Harrow and the Grange Farm site, started on 2 May 2026 for five years.
The detail is on the Harrow Council licensing pages.
- Private lets
- If you let a privately-owned flat or house here to a single household or to two unrelated sharers, you need a selective licence on it.
- Smaller shared houses
- On top of that, Harrow has run a borough-wide additional HMO licence since 2021 for smaller shared houses.
- Council-let and registered-provider homes
- These, which is most of the new estate, sit outside selective licensing.
What that means at hand-back is simple enough. The licence and the inventory are two different tests, but a clean documented to a checklist clears the ground for both in one visit: the agent gets the photo pack, the licensing standard gets its evidence the place was kept properly.
The licence and the inventory are two different tests; one documented clean clears the ground for both.
The snags a new-build flat fails on
People assume a two-year-old flat is easy. It just fails on different things. Twelve years of move-outs and a fair run of Phase 1 jobs have taught us where the clipboard stops on this estate.
Four snags come up again and again, and all four are covered free inside the 48-hour re-clean guarantee if a clerk catches one we missed.
The heat-recovery grilles
Every Phase 1 flat has supply and extract grilles for the ventilation in the bedrooms, the kitchen and the bathroom. The louvres pull dust from the day you move in, tenants almost never touch them, and a clerk only has to angle a torch up at the white plastic to see the grey.
- We unscrew them.
- We wash them in the sink and dry them.
- We put them back.
Skip it and you fail.
The timber floor
The kitchen and living area run across one continuous engineered-timber floor. Drag a sofa across it without felt pads and it greys with heel and scuff marks.
We use a polish made for wood and microfibre, never an abrasive pad and never anything acidic, and most of the marks lift.
The hall cupboard nobody opens
The heat-interface unit lives in a cupboard off the hall and gathers fluff if the door has not been opened in a year. Easy to walk past, easy for a clerk to flag. It gets cleared and the door wiped.
The hob seal
The thin silicone bead between an induction hob and the worktop is where boiled-over pasta water sets hard. It comes up with a soft brush and a non-abrasive cream, by hand.
The 57 points, and where they land on this estate
Every booking runs to the same 57-point agent-approved checklist, scaled to the property, with the full list sent through before we start. The shape of it on a Phase 1 flat:
The kitchen
- The integrated oven cavity, racks, door glass front and back (between the panes where the design allows), seals and the control fascia
- The induction hob and the seal around it
- The integrated extractor, with its filters lifted and degreased
- The integrated fridge-freezer, dishwasher and washer-dryer inside, including drum, filters and door seals
- The handle-less unit faces, including the under-edge that catches finger grease
- The worktops, taps and splashback
- The bin recess, kickboards and floor edges
Bathrooms
- The walk-in shower glass, frame and channel descaled
- The rainfall head and chrome riser
- The tile and grout, and the silicone joints
- The heated towel rail
- The vanity unit inside and out
- The extract grille
- The WC inside the rim and behind the pan
Bedrooms and the living space
- Wardrobe interiors top to bottom, and drawer runners
- Skirting, door tops and hinges, picture rails
- Light fittings and dimmer plates
- The media unit and the behind-TV dust
- Window faces, frames and any balcony track
- Radiators front, back and underneath
The parts specific to these flats
Then the things that are easy to forget:
- the heat-recovery grilles in every room, lifted, washed and refitted
- the heat-interface cupboard cleared
- the video-entry panel, thermostat and every switch and socket wiped, because finger oil shows under the LED downlights
- the floors done last, the route walked out from the kitchen so there are no prints on the way back in
Extras sit outside the package and we quote them on their own, never folded in quietly:
- outer-face glazing where access allows
- a deeper oven job on a range
- a carpet shampoo on the bedrooms in the older surrounding houses
What Affinity Water leaves on the chrome
South Harrow runs on Affinity Water, and it is properly hard. The figure for the Harrow South supply sits around 363 mg per litre, which Affinity itself classes as very hard.
On a new flat that shows up fastest on the bright chrome, where scale builds quicker than a tenant expects and a wipe with a cloth does nothing:
- the shower riser
- the rainfall head
- the basin taps
The clerk knows exactly where to look. They run a thumbnail down the tap and they catch the shower glass edge-on against the light.
We take the scale off chrome and glass with a mild descaler, keep it well away from porous tile and stone, and buff the lot dry the same day so there is nothing for the torch to pick up. It is dull work and it wins more of these flats than anything dramatic does.
On a new flat the hard water shows first on the bright chrome, and the clerk knows exactly where to look.
Three different jobs get confused on the phone, so here is the plain split:
- End-of-tenancy clean
- Built to pass the inventory and get a deposit back, measured against the check-in pack, with the flat empty and the 48-hour guarantee on it, at a fixed price by bedroom count.
- Deep clean
- A reset for a home you are keeping and living in, no formal standard to hit, from £186: £26 per cleaner per hour for two cleaners and at least three hours, plus £30 for kit.
- Regular domestic clean
- Ongoing upkeep on a weekly or fortnightly visit, the same cleaner kept on, from £23 an hour.
- Check-in inventory
- The report a clerk writes on day one. It is not a clean, but it is the document your move-out is judged against.
What it costs, against what a clipped deposit costs
Prices are fixed by bedroom count.
| Property | Typical duration | Estimated cost |
|---|---|---|
| Studio | 3-4 hours, 1 cleaner | £156 |
| 1-bed flat (Phase 1) | 4-5 hours, 2 cleaners | £207 |
| 2-bed flat | 5-6 hours, 2 cleaners | £243 |
| 3-bed flat or house | 6-8 hours, 2 cleaners | £339 |
| 4-bed house | 8-10 hours, 2-3 cleaners | £425 |
Those are full prices with kit, products and travel inside the area included. No discount lines, no “was”.
- By the hour
- If you only need a top-up rather than a full hand-back, we work by the hour at £30 per cleaner, two-cleaner minimum.
- Carpet shampoo
- Where the older houses around the estate still have it: £29 a bedroom, £36 a living room, or £94 for two bedrooms and a living room.
- Oven add-on
- £31 single, £62 double or a 90cm range. It is rare on the integrated singles but turns up on the bigger plots and the freestanding cookers on Grange Road.
The deposit maths
Now the maths nobody runs until it is too late.
- Open-market rents on a Phase 1 two-bed near Grange Farm Close have been sitting around £2,000 a month in 2026, which puts even the priciest end of our list at well under a week’s rent.
- Set a £243 clean against a deposit that can legally run to five weeks, north of £2,000 on a flat like this, and the sum makes itself.
Most people only run it after they have failed a check-out and lost the first round. The first round is the cheap one to win.
That is the point of the 48-hour re-clean guarantee: if a clerk flags any cleanliness issue within 48 hours, we come back and put it right free, as long as you tell us in that window and nobody has moved in.
It is on every booking and every postcode. It is also why we are on the books of 300+ letting agents across London, and over the years that work has helped tenants hold on to £1.2m in deposits that would otherwise have gone on deductions.
Booking it around the site fence
It is a short call. The steps:
- Ring 0333 555 2076 or email office@monstercleaning.com with the address, the block, the bedroom count and the move-out date.
- We send a fixed price by return. No “someone will call you back”.
- You confirm, and we send a booking note and a copy of the 57-point checklist.
- We turn up on the day, two to four cleaners depending on size, with our own kit and a vacuum that reaches behind the integrated units.
- You get the photo pack the same evening. Anything flagged inside 48 hours, we come back free.
One honest word on access:
- Grange Farm Close
- Kerb-side bays are resident-permit.
- The new estate
- Parking is on-street and tightly counted, with the old estate car park long gone under the demolition.
- The site fence
- The Phase 2A site fence affects parts of the estate while the build is on.
- By train
- South Harrow station, the end of the Piccadilly line up here, is about a ten-minute walk if a cleaner is coming in without a van.
Tell us the arrangement when you book, a visitor permit through the resident or the paid bays by the station, and we will time the crew so the tight bits do not snarl up the day.
If you are letting one over in the older inter-war streets on the north side of the ward, the West Harrow end-of-tenancy page covers that stock, and the borough hub at End of Tenancy Cleaning Harrow has the rest.
Two add-ons our tenants here ask for most:
- standalone oven cleaning on the freestanding cookers in the older houses
- carpet cleaning on bedrooms where the flat is carpeted rather than boarded
Questions we get asked
How much is end-of-tenancy cleaning at Grange Farm?
A studio is £156, a one-bed flat £207, a two-bed £243, a three-bed flat or house £339, and a four-bed house £425. Those are full prices with kit, products and local travel included. If you only need a partial top-up we work by the hour at £30 per cleaner, two-cleaner minimum.
Do you clean the new Phase 1 flats on the estate?
Yes, that is most of our Grange Farm work. The Phase 1 flats finished in 2023 are well finished but they fail on their own things, mainly the heat-recovery grilles, the engineered-timber floor and the integrated kitchen, so we clean to the developer hand-over standard the clerk is marking against.
Is Grange Farm covered by Harrow’s selective licensing?
Yes, if it is privately owned and let to a single household or two unrelated sharers. Roxeth ward, which takes in South Harrow and the Grange Farm site, came into Harrow’s new selective licensing scheme on 2 May 2026 for five years. Council and registered-provider homes, which is most of the new estate, sit outside it, though a small shared house anywhere in the borough may need an additional HMO licence instead.
How long does a Phase 1 two-bed take?
Around five to six hours with two cleaners. The flats are compact and well built, so the time goes on the grilles, the timber floor and the integrated appliances rather than on square footage.
Are you safe on the engineered-timber floors?
Yes. We use a polish made for wood and microfibre, and we never put an abrasive pad or an acidic descaler near it. The Phase 1 spec is engineered timber through the kitchen and living space and tile in the wet rooms, and each gets treated its own way.
What is the 48-hour re-clean guarantee?
If your inventory clerk or agent flags a cleanliness issue within 48 hours of the clean, we come back and put it right at no extra cost, as long as you tell us inside that window and nobody has moved in. It is on every job we do.
Are you insured, and will you show the agent?
Yes. We carry public liability cover, and we send the certificate to the managing agent or the council housing team whenever they ask before clearing a booking.
Can I book at short notice?
Usually, especially Tuesday to Thursday. End-of-month and Friday slots fill first, so two or three days’ notice helps if you can give it.
Do you work with the local letting agents?
We are on the books of 300+ letting agents across London and we work with the lettings desks along Northolt Road and the agents handling the estate’s re-sales, including Connells, who market homes on behalf of the council. Most of the time the tenant books and we copy the agent on the photo pack; some agents book us direct on the tenant’s behalf.
How does parking work on the estate?
Kerb-side bays on Grange Farm Close are resident-permit, and on-street parking is tight since the old estate car park went under the demolition. We sort a visitor permit through the resident or use the paid bays near South Harrow station, and we time the crew around the Phase 2A site fence where access is pinched.
Can you clean the heat-recovery vents and the heat-interface cupboard?
Always. The ventilation grilles unscrew, get washed in the sink, dried and refitted, and the heat-interface cupboard gets cleared and wiped. Skipping either is the most common reason a Phase 1 flat fails its check.
Do you charge more for a timber floor than for carpet?
No. Cleaning the engineered-timber floor is in the base price and we bring the right polish for it. Carpet shampoo is the only flooring job we charge as an extra.
How do you handle the hard-water marks?
South Harrow is in Affinity Water’s very hard zone, around 363 mg per litre. We lift the scale off chrome and glass with a mild descaler, keep it off porous tile and stone, and buff dry the same day so there is nothing left for the clerk’s torch.
What if my landlord disputes the clean?
If the work is to checklist standard and the photo pack backs it up, most disputes settle before they reach an adjudicator. If it does escalate, the deposit sits in a scheme such as the Tenancy Deposit Scheme, and Shelter’s deposit guide walks through the route. Our dated photos and checklist are admissible evidence.
