On a big detached house off Kennel Lane, the inventory clerk gives the boot room and the utility their first ten minutes, not the drawing room. That is where a Windlesham hand-back is won or lost, and it is the room the outgoing tenant has usually stopped cleaning properly by the time the van pulls away. We are Monster Cleaning Ltd, a domestic cleaning firm working across GU20 since 2014, and we scope every end of tenancy clean to that check-in report. By the hour it is £30 per cleaner, and every job carries our 48-hour re-clean guarantee. Ring 0333 555 2076 for a price on your specific house.
Last updated June 2026. We cover the whole of Windlesham and the GU20 6 postcodes, from Updown Hill and Church Road out to Woodlands Lane, Kennel Lane and the lanes towards Bagshot Heath and Sunningdale. This page sits inside the county directory at End of Tenancy Cleaning Surrey.
The boot room is where the report starts
Start with the mechanism, because the whole deposit turns on it. When you moved in, a clerk walked the house and wrote a report describing every surface, room by room, almost always with photographs. At check-out a clerk walks it again and compares the two, line by line. Anything materially worse than the check-in entry, past fair wear and tear, is chargeable against your deposit. On a four- or five-bed house with a boot room, a utility, a back kitchen and three or four bathrooms, the surface area is roughly four times that of a flat, and the deposit is large to match. When a managing agent out here holds money back, it is rarely £50. It is several hundred pounds, and a contractor of their choosing sent in to put it right.
Windlesham is not a town of flats. The stock is large gated detached houses on big wooded plots, executive and equestrian properties down the lanes towards Bagshot Heath, and period cottages near the church. Almost none of it is converted. A clerk who has inspected these houses for years knows where the work gets skipped, and the service rooms are top of that list, because they are the rooms a busy household never quite gets to. The deposit on a family let here is the kind of money worth protecting properly, and the report is the document the argument runs on.
The deposit itself sits in one of the three government-backed schemes. The bigger agents working GU20 tend to use the Tenancy Deposit Scheme or mydeposits, and the clerk’s check-in photographs are what any dispute is judged against. If the house does not match those photographs on cleanliness at check-out, the deduction stands until you can prove otherwise, and a dated set of your own photos is the only thing that reliably proves it.
“We handed back a five-bedroom house on Woodlands Lane after just over three years, two children and a dog, so it was properly lived in. What kept me up was the kitchen, an oil-fired range with a deep canopy over it, and three years of cooking had baked a hard brown film onto the canopy that I could not shift with anything I bought. The check-in report had a close photo of it. Monster sent three cleaners on the Wednesday and one of them spent most of the morning on just the range and the brick behind it. It came back to bare metal. The clerk passed the kitchen with nothing taken off, and the deposit was back through the scheme inside a fortnight.”

What the 2025 rules changed for a Windlesham move
The Renters’ Rights Act 2025 came into force on 1 May 2026. Section 21 no-fault evictions are gone, every existing assured shorthold tenancy in England has converted to a periodic tenancy, and a tenant can now give two months’ notice at any point rather than waiting out a fixed term.
Here is the part people get wrong. The cleaning side of a move-out did not change at all. An agent still cannot lawfully charge you for fair wear and tear, and that was already the rule. A greasy range canopy, a furred-up shower screen or a dirty extractor has never counted as wear and tear, and it still does not, so a deduction for any of those is as lawful today as it was last year. What the Act changed is timing. With fixed terms gone, move-outs in a high-value rental village like this become a little less predictable, and the practical takeaway is dull but it pays off: book the clean earlier than you used to, because the slot you want around month-end will be gone if you leave it. If you want chapter and verse on what an agent can and cannot withhold, Shelter’s deposit guidance sets it out plainly.
The cleaning side of a move-out did not change at all.
Why Surrey Heath stays quiet on licensing, and the catch
This is the bit non-locals get wrong. Surrey Heath Borough Council runs only the mandatory HMO regime: a licence is needed where five or more people from two or more households share a house. The council has not brought in an additional or a selective scheme covering smaller three- and four-person sharer lets, unlike a number of London boroughs. You can confirm the brackets on the council’s own houses in multiple occupation pages if you are not sure which one your tenancy fell into.
That sounds like less paperwork, and it is. The catch is at hand-back. With no selective scheme, there is no council inspection baseline on the mid-size sharer houses, so the managing agent’s own check-in report becomes the only standard the property is held to, and the reports out here are detailed. We have handed back sharer houses near the lanes where the clerk had itemised the inside of every wardrobe and the seal on every shower. A lighter licensing touch does not mean a lighter clean. It means the clerk’s report is the whole exam, and you want to have read it.
Hard water off the Egham works, not soft sand
People assume the heath under Windlesham means soft water, because the Bagshot sands are acidic ground. The tap tells a different story. The mains supply here comes from Affinity Water, and GU20 sits in their Bagshot/Sunninghill supply zone, fed from the Egham treatment works. That zone runs at an average total hardness around 288 milligrams of calcium carbonate per litre, which is firmly hard water, near the top of the band. The geology of the heath is one thing; what comes out of the treatment works is another, and on these houses it shows.
In a house this size, scale turns up everywhere a clerk looks: the mixer in the family bathroom, the screen in the second bathroom, the inside of the kettle, the spray arms in the dishwasher, and the chrome on a big walk-in enclosure. Outgoing tenants tend to clean the kitchen and the master and run out of steam before the en-suites, which is exactly where the scale is worst and exactly where the clerk goes first. Long corporate and relocation lets make it worse. A senior household posted here for two or three years is often busy and away at weekends, and over that length of time a hard supply lays down a genuinely etched film on glass and chrome that a sponge and a supermarket spray will not move. We treat every bathroom in the house as a descaling job from the outset, not a wipe-down, because in GU20 that is what it is.
The period cottages near the church have the same supply but a different failure. Smaller bathrooms, often just one, frequently with older enamel and chrome that marks faster and that nobody has descaled in years. Original fittings need taking back without scouring the surface to bits, which is slower than a modern enclosure, and it is exactly the sort of thing a clerk lingers over on a cottage check-out.
“Ours was a two-bedroom cottage just off Church Road, near the Half Moon, and we’d been there five years. One bathroom, old taps, and the limescale on the shower glass had gone cloudy in a way no spray I tried would touch. I genuinely thought the screen was just old. The Monster cleaner took it back to clear glass in an afternoon and showed me where it had been worst. The agent’s clerk wrote nothing up on the bathroom, which after five years felt like a small miracle.”
Priya, former tenant, Church Road GU20, February 2026
The 57 things we work, room by room
Every Windlesham booking runs to a 57-point agent-approved checklist, built over a decade of local check-outs and tuned to what the clerks here actually flag. The full list comes with the job, or we walk you through it before we start. Here is the shape of it.
Kitchen, utility and boot room
The oven is stripped and degreased inside, racks, door glass and the bottom plate included. Hob, splashback and the extractor or range canopy degreased. Behind and beneath the cooker and the fridge-freezer where the report photographs reach. Sink and mixer descaled. Every cupboard and drawer cleared and wiped inside and out. Then the rooms that decide it on these houses: the utility done properly behind and under the washer and dryer, the sink, the floor and the skirtings, and the boot room floor and skirtings cleaned to the same standard, because that is the first room the clerk inspects.
Bathrooms and en-suites
Every bathroom in the house, not just the family one. Showers, screens and enclosures descaled until the chrome and glass are genuinely clear. Tile grout, basins, baths, taps and the loo cleaned and the scale taken off. Extractor vents wiped. Mirrors and glass shelving left without streaks or a hard-water haze. In a four- or five-bathroom house this is where the morning goes, and it is the right place for it to go.
Bedrooms, reception rooms and throughout
All the reception rooms, the study, the bedrooms and any boot room or loggia, dusted top to bottom: skirtings, picture rails, cornicing and the tops of doors and frames. Interior windows, sills and reveals cleaned. Fitted wardrobes wiped inside. Light fittings and switch plates done. Carpets vacuumed through, hard floors washed. Cobwebs cleared from the high corners and stair voids the cleaners can safely reach. Paintwork spot-cleaned where scuffs would otherwise be itemised.
In the older houses and cottages near St John the Baptist this part takes longer than people budget for, and it is worth saying why. Deep window reveals and original stone or timber sills collect a season of grime a tenant never sees from inside the room but a clerk photographs straight away in daylight. Cornicing and picture rails in the period rooms hold dust nobody has reached in years. Narrow cottage stairs scuff along one wall where everyone’s shoulder catches the paint, and that scuffing gets written up every time. The big detached houses off Woodlands Lane have the opposite problem, which is sheer volume: four reception rooms, a study, a boot room and a loggia is a great deal of skirting, door tops and fitted-wardrobe interior, and the clerk works through all of it with the check-in report open. We scope the number of cleaners to the house so none of it gets rushed at the end of a long day.
A lighter licensing touch does not mean a lighter clean.
Updown Hill to the lanes: the stock changes street by street
We run jobs right across the village and the lanes around it, and what gets flagged shifts with the kind of house. The roads we are in most:
- Updown Hill and the parade at the village centre
- Church Road, down past St John the Baptist and the Half Moon
- Kennel Lane and the Field of Remembrance end
- School Road and the lanes running off it
- Woodlands Lane and the larger detached plots
- The roads towards Bagshot Heath, Chobham Common and Swinley Forest
- The cottages and older houses near the Brickmakers
- The executive and equestrian plots out towards Sunningdale
The pattern is consistent enough that we brief new cleaners on it before their first GU20 job. In the big detached houses off Woodlands Lane and the Bagshot Heath side, it is the service rooms: the boot room floor and skirtings, the utility behind the machines, the scale in the second and third bathrooms, and the canopy over a range or an Aga. In the period cottages near the church it is different again: deep window reveals and original sills, picture-rail and high cornice dust, scuffed paint along narrow stair runs, and old kitchens where grease has worked into the gaps around a freestanding cooker. In the larger sharer houses the clerks go room by room with the report, and the failures are always the same: inside wardrobes, behind bedroom doors, fridge seals, and a shower screen nobody descaled. Across every property type, the single most common write-up here is an oven the tenants believed was clean. The clerk opens the door, pulls the racks, and lifts the bottom plate, every time.
Not sure whether your road counts as Windlesham, Bagshot or Sunningdale at the boundary? Ring 0333 555 2076 with the postcode and we will tell you in about ten seconds. We also clean over the line in Bagshot and Lightwater if your move is just down the road.
What it costs, and the sum nobody runs in time
| Property | Typical duration | Estimated cost |
|---|---|---|
| Studio or annexe | 3-4 hours, 1 cleaner | From £156 |
| 1-bed flat or cottage | 4-5 hours, 2 cleaners | From £207 |
| 2-bed cottage near the church | 5-7 hours, 2 cleaners | From £243 |
| 3-bed house | 6-8 hours, 2 cleaners | From £339 |
| 4-bed detached (the common one here) | 8-10 hours, 2-3 cleaners | From £425 |
| 5-bed-plus detached or equestrian | Full day, 3 cleaners | Quoted on the layout |
| Carpet shampoo add-on | Same visit | From £36 a room |
| Oven deep-clean, itemised on its own | 1.5-2 hours | From £77 |
Windlesham runs on our standard schedule, no central-London premium added. Studios start at £156, one-beds £207, two-beds £243, three-beds £339, and four-beds £425, which is the common job here given the stock. Genuinely large five- and six-bedroom houses are quoted on the room and bathroom count, so call with the layout. If you would rather we worked to time, it is £30 per cleaner per hour. Carpet shampoo is an add-on at £36 a bedroom, £43 a living room, or £115 for whole-flat carpet on a two-bed, and an oven done on its own is £77 for a single, £110 for a double and £114 for a 90cm range. Every figure is the price for the work described above, not a teaser that grows on the day.
Run the sum the way the deposit makes you. A four-bed at £425 to protect a deposit several times that is not really a decision, yet most tenants only do that arithmetic after they have tried, failed the check-out, and lost the first round. We have recovered £1.2m in deposits for tenants since 2014, and we are on the books of 300+ letting agents across our regions, the independents and the national branches active around Windlesham, Bagshot and Sunningdale among them. Our first-time pass rate is 97%, which means roughly one clean in thirty gets something queried, and when that happens the 48-hour re-clean guarantee applies: tell us within three days, we come back and put it right, no second charge.
People ask which clean they actually need, so here is the plain distinction.
- End of tenancy clean
- Scoped against the inventory and aimed at the clerk’s sign-off and your deposit, with the house empty and the 48-hour guarantee on it. This is the one this page is about.
- Deep clean
- The same intensity of work, but for your own benefit in a house you are keeping, with no inventory driving it and no deposit at stake.
- Regular clean
- Lighter, on a rota, to keep a home in shape between the big ones.
- Domestic clean
- Ongoing household help, weekly or fortnightly, the same cleaner kept on the house. A different service from a hand-back, not scoped to a check-out.
If carpets are in the picture, our carpet cleaning can run the same morning, and the oven cleaning team handle range and Aga canopies if it is only the kitchen you need brought up to standard. Both slot into the same visit so the clerk sees a finished house in one pass.
Booking it round the village
Booking is short.
- Ring 0333 555 2076 or email [email protected] with the Windlesham address, the number of bedrooms and bathrooms, and your check-out date.
- We give you a fixed price for that specific house, not a from-price. Larger detached houses get a quick layout check first.
- We confirm a slot, ideally after the removal van has gone so we clean an empty house.
- Two to four cleaners attend depending on size, working to the 57-point checklist.
- If the clerk flags anything cleaning-related within 48 hours, we come back and resolve it at no extra cost.
One ask: book the clean for after the movers, not before. We cannot guarantee a hand-back standard on a house that still has furniture in it. For move-day logistics, our removals team can take the heavy lifting off you so the clean lands on an empty, finished house, which matters on the narrow lanes here where several van trips otherwise turn into a long day.
“We let a four-bedroom house out towards the Sunningdale side for almost two years on a corporate posting and left in a rush at month-end. I rang on the Monday for the Thursday, half expecting to be told there was nothing. They fitted us in, sent three cleaners, and worked off the agent’s check-in list room by room. Newton Rowe’s clerk passed it with one tiny re-clean on a single en-suite, which Monster came back and sorted the next morning. Full deposit returned. Worth every penny of the booking.”

Questions we get asked
How much is end of tenancy cleaning in Windlesham?
From £156 for a studio, £207 for a one-bed, £243 for a two-bed, £339 for a three-bed and £425 for a four-bed. There is no central-London premium added out here. Larger detached houses off Woodlands Lane or the Bagshot Heath lanes are priced on the room and bathroom count, so call with the layout and we will give you a fixed figure.
Do you guarantee the clean will pass the inventory check?
We back it with a 48-hour re-clean guarantee. If the inventory clerk or managing agent flags anything cleaning-related within three days of the clean, we come back and put it right at no extra charge. Our first-time pass rate across these houses is 97%.
Is the oven included, or is it an add-on?
The oven is fully included in the end of tenancy price: stripped and degreased inside, with racks, door glass and the bottom plate. We only quote ovens separately, at £77 for a single, £110 for a double and £114 for a 90cm range, if you want just the kitchen done rather than a full clean.
Why does hard water matter so much in Windlesham?
GU20 is on Affinity Water’s Bagshot/Sunninghill supply zone, fed from the Egham works, and it averages around 288 milligrams of calcium carbonate per litre, which is firmly hard water. Scale builds fast on screens, mixers, kettles and dishwasher arms, and it is the most common thing clerks photograph in the en-suites of the larger houses here. We descale every bathroom back to clear glass and chrome as part of the standard clean.
Isn’t the water soft, given the sandy heath the village sits on?
No, and it catches people out. The Bagshot sands are acidic ground, but the mains supply is treated water from the Egham works and comes through hard. The geology under your feet and what runs from the tap are two different things, and the tap is what scales the bathrooms.
Do you cover the lanes towards Bagshot Heath and Sunningdale, not just the village centre?
Yes. We work Updown Hill, Church Road, Kennel Lane, School Road and Woodlands Lane, plus the executive and equestrian plots running out towards Bagshot Heath, Chobham Common and the Sunningdale side. The whole GU20 patch is covered.
Can you clean a large detached or equestrian property, not just a flat?
That is most of what we do in Windlesham. Five- and six-bedroom detached houses with several reception rooms, a boot room, a utility and multiple bathrooms are the normal job here. We send three or four cleaners and scope the price to the actual layout.
Does the Renters’ Rights Act mean my landlord cannot charge me for cleaning now?
No. The Act, live from 1 May 2026, changed evictions, fixed terms and notice periods. It did not change the principle that you hand a property back clean. A greasy range canopy or a limescaled shower has never been fair wear and tear, and a deduction for it is still lawful.
Does Surrey Heath require an HMO or other licence on the house I am leaving?
Surrey Heath runs only mandatory HMO licensing, which applies where five or more people from two or more households share. There is no additional or selective scheme here, so a typical family let or small sharer house is not licensed. Either way the agent’s check-in report is the standard your clean is judged against.
Do I need to be there when you clean?
No, and most clients are not. We collect keys or use an agreed key-safe, clean the empty house, and let you and the agent know when it is finished. It is better if the property is fully cleared first so we can reach every surface.
What happens if I booked the clean but the removal van runs late?
Tell us as soon as you know. We would rather move the slot than clean around furniture, because we cannot guarantee a hand-back standard on a part-emptied house. There is no charge to reschedule when you give us reasonable notice.
Do you clean carpets and the range canopy at the same visit?
Yes. Carpet shampoo, at £36 a bedroom and £43 a living room, and the range or Aga canopy degrease can be done in the same morning as the main clean, so the clerk inspects a finished house in one pass rather than over several visits.
How quickly can you come out, and how do I get a fixed quote?
Usually within a few days, and often next-day in a quiet week, though end of tenancy dates cluster around month-end so the more notice the better. For a fixed quote rather than a from-price, ring or email with the full address, the number of bedrooms and bathrooms, whether carpets and the oven are in scope, and your check-out date. For larger houses we do a quick layout check, then give you one fixed price with the 57-point checklist behind it.
