The terrazzo entrance steps inside The Lawn, Frederick Gibberd’s 1951 tower block on the edge of Old Harlow, are original, and an inventory clerk photographs them on the way in more often than you’d think.
Monster Cleaning has worked end of tenancy jobs across CM17 to CM20 since 2014: the ex-council semis and maisonettes that make up most of Harlow’s rental stock, the mansion flats inside The Lawn itself, and the newer townhouses going up at Newhall and Gilden Park. A fixed price by bedroom count, a 48-hour re-clean guarantee on every job. Ring 0333 555 2076 for a price.
Last updated July 2026. We cover CM17, CM18, CM19 and CM20 across Harlow town centre, Mark Hall, Bush Fair, Great Parndon, Church Langley, Staple Tye and the Newhall and Gilden Park development, plus the edge of Old Harlow. This page sits inside the Essex directory at End of Tenancy Cleaning Essex.

Harlow was designated a New Town in 1947, one of the first wave under the New Towns Act, and Frederick Gibberd drew the whole thing as a set of self-contained neighbourhoods rather than one sprawling estate. Each one got its own primary school, its own shops, its own church, arranged around a green.
Mark Hall, Bush Fair, Great Parndon and, later, Church Langley all follow that same idea, even though they were built decades apart.
What that means for a cleaning job is dull but real. Most of the properties we’re booked into are the original ex-council semis and maisonettes from the 1950s and 60s, now sold off and privately let, and they share the same handful of construction quirks whatever street they sit on.
Crittall windows
Steel-frame Crittall casement windows are the big one. Harlow’s Mark I stock used them everywhere, and most landlords never swapped them out. The painted steel channel along the bottom rail holds a decade of condensation and dust that a normal cloth glides straight over.
We had a Bush Fair maisonette in June where the tenant had wiped the sills every week for three years and the clerk still ran a finger along the Crittall rail and came away black on the first pass. Fifteen minutes with the right cloth and a pH-neutral cleaner and it was gone.
Terrazzo
It shows up in odd places across the older stock:
- entrance steps
- porch thresholds
- sometimes a hallway strip
Original Gibberd-era terrazzo scratches if you attack it with anything abrasive, so we clean it slow and by hand rather than machine it.
Renters’ Rights Act 2025, what actually changed on 1 May 2026
The Renters’ Rights Act 2025 went live on 1 May 2026.
- Section 21 no-fault eviction is gone.
- Every assured shorthold tenancy in England converted to a rolling periodic tenancy that day.
- None of it touches what a cleaning job needs to look like at hand-back.
The deposit-protection schemes still judge against fair wear and tear, and a written check-out report cross-referenced to the original inventory is what an adjudicator expects, now more than ever. That’s the standard our 57-point agent-approved checklist is built to meet.
Article 4, and the streets where splitting a semi into bedsits now needs planning permission
Harlow does run an Article 4 direction, and it covers HMO conversions across the whole town, not just a handful of streets. Mark Hall North, Morley Grove, Old Harlow and Churchgate Street each carry an extra direction on top of that, tightened after specific problems with badly-run shared houses.
In practice it means a landlord can’t quietly split a Mark Hall three-bed semi into six lettable rooms without going through planning first.
- It doesn’t change what we clean.
- It does mean the agents we work with tend to run a tighter inventory than in a district with looser rules, because the council’s own paperwork is stricter.
A town being rebuilt around the one you know
Harlow is mid-way through the biggest change to its economy since Gibberd’s original plan.
The UK Health Security Agency campus
- Confirmed
- By the government in July 2025
- What moves here
- The UK Health Security Agency’s scientific facilities from Porton Down and Colindale, plus its head office from Canary Wharf
- The site
- A 40-acre campus
- Once it’s running
- Expected to carry around 2,750 permanent jobs and put roughly £80m a year into the local economy
- First buildings
- Not due until the mid-2030s
So nothing about the rental market changes tomorrow, but agents are already telling us they’re fielding more corporate relocation enquiries than they were two years back.
Harlow and Gilston Garden Town
Separately, the Harlow and Gilston Garden Town programme is rebuilding the town centre itself.
- Market Square is mid-redevelopment as this goes to print.
- The wider scheme carries roughly £1.3bn of infrastructure spending attached to around 23,000 planned new homes stretching from Newhall in the east to the Gilston villages over the Hertfordshire border.
We picked up a Newhall townhouse job in the spring for a build-to-rent operator running its own corporate inventory, closer to a hotel checklist than a normal landlord’s, with the polished-stone worktops and integrated appliances checked against a spec sheet rather than a clerk’s eye.
From The Lawn to Newhall: the stock changes street by street
The Lawn
The Lawn itself is worth a paragraph on its own.
- Completed
- 1951, for the Festival of Britain
- Listed
- Grade II in 1998
- Standing
- Usually credited as one of the first residential tower blocks built in England
- Design
- A butterfly-shaped ten storeys designed around the mature oak trees already on the site, so every flat gets a south-facing balcony
The flats inside turn over reasonably often as rentals, and the inventory reports on them read differently to anything else in the town: original terrazzo, the entryphone panel by the door, balcony rail and glazing, all itemised by name because the block’s listed status means nobody wants to be blamed for damage to something historic.
Original terrazzo, the entryphone panel by the door, balcony rail and glazing, all itemised by name.
The rest of the town
- Mark Hall and Bush Fair
- The classic Gibberd neighbourhoods: ex-council semis and low-rise maisonettes, flat-roofed porches, Crittall windows, the odd tile-surround fireplace still fitted in a reception room that’s never had a fire lit in it in twenty years.
- Great Parndon and Staple Tye
- The same template a decade or so later, slightly bigger gardens, the same steel windows.
- Church Langley
- Different again: a 1990s estate built as one planned phase rather than grown neighbourhood by neighbourhood, mostly two- and three-bed private-build houses with UPVC everywhere and none of the Crittall problem.
- Old Harlow
- It sits outside all of this. It predates the New Town by centuries, a proper village core with timber-framed cottages along the High Street, and it runs on a separate page with a separate scope because the property stock has almost nothing in common with the rest of the town.
- Newhall and Gilden Park
- The newest layer, 2000s and 2010s New Urbanism townhouses east of the railway with narrow frontages, integrated kitchens and the odd shared courtyard.
Newhall and Gilden Park mean different products, different pace, and usually a shorter job than the Gibberd-era stock, because there’s less original fabric to work carefully around.
The 57 things we check, room by room
This is the 57-point agent-approved checklist every Harlow booking runs against, tuned over a decade of local hand-backs to what the clerks on this patch actually flag. A signed copy goes to your inventory clerk with the invoice.
Kitchen
- Oven cleaned by hand, not wiped: single oven as standard, double oven and 90cm range cooker priced as add-ons
- Hob rings and trim off and washed, extractor filter soaked separately
- Cupboard interiors, shelf edges and door tops
- Splashback and worktop worked with a pH-neutral cleaner, stone-safe on the Newhall properties
- Fridge and freezer interiors, drip tray hand-washed
- Crittall casement reveal on the ex-council kitchens worked by hand with a soft cloth, never a wire pad on the painted steel
Bathrooms
- Shower screens and taps taken back through the hard-water film with a controlled descaler
- Grout worked on a soft brush rather than scrubbed blind
- Bath panel off where it’s screwed rather than glued, floor and pipework behind it cleaned
- Toilet base, cistern and the collar around the soil pipe
- Mirror cabinets cleared and the glass behind them wiped
Bedrooms and living areas
- Skirting throughout, top and front face
- Crittall reveals and locking pegs worked in every room that has them
- Window sills and any condensation line along the sealant
- Tile-surround fireplace cleaned back to the glaze where one is still fitted, hearth and grout brushed soft rather than wired
- Wardrobe interiors, shelf edges, drawer runners
- Carpet edges hoovered against the gripper
Throughout
- Light switches, sockets, door handles and architraves
- Radiator panels front, back and the bracket where it’s reachable
- Stairs and bannister hand-cleaned where the property has them
- Loft hatch wiped
Final walk against the checklist before we leave, every room, no exceptions.
End of tenancy versus everything else
Tenants and landlords muddle these up more than you’d think, so here’s the plain distinction we give on the phone.
- Check-in inventory
- The report a clerk writes on day one, describing every surface, usually with photos. It’s the standard your check-out gets measured against, which is why we clean to it rather than to a general idea of tidy.
- End of tenancy clean
- Built to pass that inventory and protect the deposit, priced by property size, with the 48-hour re-clean guarantee attached.
- Deep clean
- A one-off reset for a home you’re keeping, moving into, or recovering from building work. No inventory standard to hit, priced by the hour.
- Regular domestic clean
- Ongoing weekly or fortnightly maintenance while you’re living there, from £23 an hour on a weekly visit.
What it costs, and the sums nobody runs until hand-back day
| Property | Typical duration | Estimated cost |
|---|---|---|
| Studio flat (Town Centre, Bush Fair) | 2-3 hours, 1 cleaner | £176 |
| 1-bed flat (Town Centre, Staple Tye) | 3-4 hours, 1-2 cleaners | £227 |
| 2-bed maisonette (Great Parndon, Church Langley) | 4-5 hours, 2 cleaners | £263 |
| 3-bed Gibberd-era semi (Mark Hall, Bush Fair) | 5-6 hours, 2 cleaners | £359 |
| 4-bed Newhall or Gilden Park townhouse | 6-8 hours, 2-3 cleaners | £445 |
| Carpet add-on, per bedroom | Same visit | £29 |
| Oven add-on, single | Same visit | £31 |
Harlow prices are fixed by bedroom count, kit and products included, with no separate call-out charge. A part property or an unusual layout is £30 per cleaner per hour.
These cost more, and we say so on the phone rather than after the invoice lands:
- a long tenancy with heavy wear
- a pet in the property
- a kitchen that hasn’t had a proper clean in three or four years
Run the sum the way the deposit does. A three-bed Mark Hall semi at £359 protecting a deposit north of £1,500 barely counts as a decision once you’ve done it once.
Every Harlow booking carries the 48-hour re-clean guarantee: flag anything in writing inside that window and we come back and fix it at no charge.
There is a reason letting agents on this patch know us. We’re on the books of 300+ letting agents across London and the Home Counties, including William H Brown on Broad Walk here in Harlow, and that work has helped tenants recover £1.2m in deposits that would otherwise have gone on cleaning deductions.
Why block-specific knowledge matters at The Lawn
We get asked about The Lawn often, and the answer is block-specific knowledge.
A ten-storey listed tower and a two-bed maisonette in Staple Tye do not fail on the same items. Sending a cleaner who already knows which two things this particular agent checks on this particular block is worth more than an extra hour of scrubbing anywhere else.
How booking works
Booking takes three steps
- Your postcode and the property. The form gives the price.
- A date that suits you. Seven days a week.
- We confirm it with you by phone or WhatsApp.
0333 555 2076 · 8am to 7pm
- Ring 0333 555 2076 or email office@monstercleaning.com with your postcode, bedroom count, hand-back date and your agent’s name. Tell us if it’s a Gibberd-era semi with original Crittall windows, a flat inside The Lawn, a Newhall townhouse or an Old Harlow cottage; it changes what we send.
- We confirm the slot and the all-in price in writing, usually within a couple of hours during office time.
- Cleaners arrive with the 57-point checklist, all products and equipment, and whatever specialist kit the property needs, hard-water descaler as standard everywhere.
- The lead cleaner does a final walk against the checklist. Signed copy left on the counter or emailed to you and your agent.
- Your clerk walks the property. Anything flagged in writing inside 48 hours, we come back and fix it free.
Questions we get asked
How much does end of tenancy cleaning cost in Harlow?
Studio £176, 1-bed £227, 2-bed £263, 3-bed £359, 4-bed £445. All-in, agent-approved, with the 48-hour re-clean guarantee included. Carpet and oven add-ons are quoted separately before we start.
How long does the clean take?
A three-bed Gibberd-era semi in Mark Hall or Bush Fair usually runs five to six hours with two cleaners. A four-bed Newhall or Gilden Park townhouse runs six to eight hours with two or three. We send a team sized to the property rather than a fixed pair, because Harlow’s stock varies a lot by era.
Do you guarantee my deposit back?
We guarantee the clean against the inventory clerk’s checklist for 48 hours; if anything is flagged in writing inside that window, we return and redo it free. No cleaning company can promise the deposit itself, since deductions can cover damage as well as cleaning.
Are you insured?
Yes. Public liability cover plus treatment risk on the cleaning kit itself. Certificate sent on request before the booking is confirmed.
Do I need to be there for the clean?
No. Most Harlow hand-backs are key-collection jobs, keys picked up from the agent and dropped back the same day. Tell us the arrangement when you book.
Do you handle flats inside The Lawn or other mansion blocks?
Yes, regularly. The Lawn’s Grade II listing means the agent’s inventory itemises things like the entryphone panel, balcony rail and original terrazzo individually, so we brief the team on the specific items that block’s clerk checks before we send them.
Do you clean the newer Newhall and Gilden Park townhouses?
Yes. That stock is post-2000 with integrated appliances and stone worktops, often on a corporate build-to-rent inventory rather than a standard landlord one. We work to whichever spec sheet the operator sends.
What’s different about a Harlow ex-council semi or maisonette?
Mostly the Crittall steel-frame windows, which most landlords never replaced. The painted steel channel along the bottom rail traps grime a normal cloth will not shift, and it is one of the most-flagged items on this era of Harlow stock.
Has Harlow Council restricted converting properties into HMOs?
Yes. There is an Article 4 direction covering HMO conversions across the whole town, with extra directions on top for Mark Hall North, Morley Grove, Old Harlow and Churchgate Street. It affects planning, not the standard we clean to.
Does Essex hard water affect the clean?
Essex & Suffolk Water rates the local supply as very hard, well above 300mg/l of calcium carbonate, so limescale builds fast on taps, shower screens and kettles. We use a controlled descaler rather than anything acid-based on original chrome or brass fittings.
Do you cover Old Harlow separately?
Old Harlow has its own page. The property stock there, timber-framed cottages along a genuine High Street, predates the New Town by centuries and needs a different scope to the Gibberd-era semis and maisonettes that make up the rest of the town.
What happens if my landlord disputes the clean?
Escalate to your deposit scheme’s adjudication process, whichever protects your deposit; that usually means TDS, DPS or mydeposits. Our invoice and the signed checklist are evidence a tenant with a professional clean on record rarely needs to argue hard with.
How quickly can you book me in?
Same week on most CM17 to CM20 postcodes, sometimes next day if you call before 11am. End-of-month hand-backs book up first, so ring a little earlier for those.
