Aldersgate Street is named after a gate. The Roman and medieval City wall ran through here, and the gate that stood near the top of the street gave its name to the ward, to a Tube station, and eventually to this corner of the EC1A and EC2Y postcodes. Barbican station, the one most Aldersgate tenants use, opened in 1865 as Aldersgate Street station, became plain Aldersgate in 1910, then Aldersgate and Barbican, and only took its current name in 1968. The history is on the platform signs. The point for a departing tenant is simpler: the homes around this old gate are unusual, and so is the clean they need at the end of a tenancy.
We are Monster Cleaning, a London domestic-cleaning firm working since 2014, and end of tenancy work in the City is a steady part of what we do. This page sets out how a deposit-back clean works in Aldersgate, what the City of London Corporation does and does not require of your landlord, what the job covers, and what it costs. If you would rather just talk it through, call 0333 555 2076 or email [email protected] for a fixed quote, usually back within two working hours.
Three kinds of home behind one postcode
Walk the ward and you pass three completely different sorts of home, often within a few minutes of each other. Each one cleans differently, and treating them the same is how cleaners lose tenants their deposits.
First, the Barbican Estate. The western blocks sit inside Aldersgate ward: Seddon House, John Trundle Court, Thomas More House, Mountjoy House, Willoughby House, and the lower floors of Shakespeare Tower and Cromwell Tower facing the street. The estate was designed by Chamberlin, Powell and Bon, built between 1965 and 1976, and listed Grade II in 2001. It holds over 2,000 flats. The finish is board-marked concrete, used as both structure and surface, and concrete behaves nothing like painted plaster. It traps cooking grease in its texture and holds dust in every groove of the ribbed service cores. The original floors are oak block parquet laid on bitumen, and they must never see a wet mop or a steam machine. Any cleaner who reaches for either has not worked the estate.
Second, the new build. Barts Square on Bartholomew Close, finished over the last decade, is glass, engineered stone and polished concrete. Dominion House, Vicary House and Abernethy House run to large-format porcelain floors, handleless kitchens, induction hobs and full-height sliding glazing that gathers dust in its tracks and water spots on the glass. The chemistry here is the opposite of the Barbican job. You want neutral-pH cleaners on the stone, alkaline degreasers on the induction surfaces, and a soft pad on the porcelain so the polish is not dulled.
Third, the conversions. Along Aldersgate Street, Little Britain and the lanes near Cloth Fair sit warehouse and period buildings turned into flats, including the service flats at London House, number 172. These keep older features: timber boards that pre-date rubber-backed matting, cornicing, the odd run of original windows. They want a third approach again, gentle on old timber, careful around plaster mouldings.
So one move-out clean might mean conditioning oak parquet without a drop of water; the next, polishing a wall of glass and a stone worktop; the next, lifting decades of grime off a converted warehouse floor. We carry pad sets and chemistry for all three as standard, because in this ward you genuinely cannot guess which you will meet.

Why a City clerk’s report runs longer here
The City of London is England’s smallest local authority by resident population, yet the homes inside it are far from ordinary. That mismatch is the whole story of why deposits get held back here.
Rents behind these addresses sit well above the London average, and the deposit follows the rent. Under the five-week cap set by the Tenant Fees Act 2019, deposits on EC1A and EC2Y flats commonly land between £2,000 and £5,500. When that much money is sitting in a scheme, a landlord’s agent has every reason to read the check-out report closely, and a clerk writing for that agent itemises things a clerk in a cheaper market would wave through. A grease haze on a concrete soffit. A water mark where a wet mop touched parquet. A dust line on a sliding-door track. Each becomes a line on a schedule, and each line is money.
The housing stock itself lengthens the report. Board-marked concrete ceilings, exposed service pipework, galley kitchens ducted through a shared riser, listed windows that cannot simply be swapped if scratched, oak parquet that shows every careless mop: these are all inventory items, and all of them get checked. A clerk in a plain new-build elsewhere has a shorter list because there is less that can go wrong. Here, there is more, which is exactly why the clean has to be built around the report rather than around a generic room-by-room habit.
This is the gap a proper end of tenancy clean closes. Over the years we have helped tenants recover £1.2m in deposits that would otherwise have gone on cleaning deductions, and a fair share of that has been in flats exactly like these, where one missed detail on a long clerk’s list is the difference between a full return and an argument.
Licensing in the Square Mile, and why it puts the weight on your clean
Most London boroughs run extra property-licensing schemes on top of the national rules. The City of London does not, and that changes where the pressure falls when you move out.
Here is the verified position. The City of London Corporation operates mandatory HMO licensing under Part 2 of the Housing Act 2004: any home let to five or more people forming two or more households who share a kitchen or a bathroom must be licensed, with fees running from around £1,050 upward and a possible fine of up to £20,000 for operating one without a licence. What the Corporation does not run is an additional HMO licensing scheme or a selective licensing scheme, and on the public record it has no plans to bring either in. Most Aldersgate lettings are self-contained flats anyway, so they fall outside the HMO definition altogether.
For you as a departing tenant, that absence matters more than it first looks. In a borough with selective licensing, there is a council register and a set of licence conditions sitting over the landlord, giving a tenant a second lever in a dispute. In the City there is no such register acting as a backstop. The condition and cleanliness of your flat at check-out, recorded against your signed inventory, is the main thing protecting your deposit. There is no licensing paperwork to fall back on, which is precisely why the photographed, dated clean does so much of the heavy lifting here.

Your deposit itself is still protected, of course. By law your landlord must place it in a government-backed scheme, the three for England being TDS, DPS and mydeposits, and protected within 30 days of being taken, as the gov.uk guidance for landlords sets out. What the scheme cannot do is make a flat clean. That part is on you, or on whoever you book.
What the Renters’ Rights Act changes for a Barbican move-out
From 2026 the rules around ending a tenancy are tighter and better documented, which cuts both ways for a deposit.
The Renters’ Rights Act 2025 replaces the old Section 21 no-fault eviction route with assured periodic tenancies and firms up the grounds on which money can be held back from a deposit. For a tenant leaving a Barbican, Barts Square or Cathedral Lodge flat the practical effect is that disputes now sit inside a more evidence-driven process, and the clerks writing check-out reports are working to a higher bar. Fabric condition, cleanliness, and the line between fair wear and genuine damage all get recorded in more detail than they used to be.
That detail is good news if your evidence is good and bad news if it is thin. A clean that is inventoried, dated and photographed is the cheapest insurance you can buy against a contested return, and it lines up neatly with the way the schemes resolve arguments. If a deduction is challenged, the scheme’s adjudicator weighs the paperwork from both sides, and the free dispute resolution service the schemes provide turns on exactly that evidence. A photo pack showing the flat clean on the day you left is hard to argue with.
The streets and blocks we turn up to
We cover every residential address inside Aldersgate ward and the homes just over its edges. The list below is not the whole of it, but it is where we end up most often:
- Aldersgate Street itself, including London House at 172, Cathedral Lodge and the numbered blocks
- Bartholomew Close and Barts Square (Dominion House, Vicary House, Abernethy House)
- Little Britain, King Edward Street and Angel Street
- Seddon House, John Trundle Court, Thomas More House, Mountjoy House and Willoughby House on the Barbican Estate
- The street-facing flats of Shakespeare Tower and Cromwell Tower
- Noble Street, Gresham Street and the Barbican high-walk addresses off Beech Street
- Newbury Street, Kinghorn Street and Cloth Fair near West Smithfield
- Postman’s Park and the lanes around St Botolph-without-Aldersgate
- The EC1A stretch of Goswell Road and Glasshouse Yard
If your tenancy agreement reads EC1A, EC2Y or a Barbican block postcode, we clean it. The wards next door run on the same teams: the eastern Barbican blocks around Cripplegate, the market end at Smithfield, and the City fringe up towards Clerkenwell and Islington across the boundary. The full hub sits on our City of London page.
One honest local note. Access, not cleaning, is the slow part around here. Half these flats reach their front doors off the Barbican high walks rather than a normal street, the goods lifts have to be booked, and there is effectively nowhere to park a van, so we plan the kit we carry around that. It is worth knowing before moving day, not on it.
What a 57-point clean actually covers
Every Aldersgate clean follows the same 57-point list, written to read across against an inventory clerk’s report. It is grouped by room below, with the Barbican, Barts Square and conversion details called out where they bite.
Kitchen
- Oven taken back to bare metal: racks, roof, base, door glass inside and between the panes where it comes apart, seals and hinges
- Extractor hood, filters and any ducting reachable from the hood; Barbican mesh and baffle filters soaked, Barts Square recirculating filters checked and cleaned
- Hob or induction surface descaled, burner caps lifted; an AGA descaled on its own approved chemistry where there is one
- Splashback tiling, grout and any under-cabinet lighting wiped clear of cooking film
- Unit doors, handles, plinths and toe-kicks degreased; interiors emptied, vacuumed and wiped, runners included
- Worktops polished, with engineered stone and quartz kept on pH-neutral chemistry
- Sink and taps descaled, waste flushed, overflow cleaned
- Fridge and freezer defrosted and wiped, seals detailed, drip trays emptied
- Dishwasher filter and spray arms cleaned; washing machine drum, drawer and door seal cleaned and the filter emptied
- Microwave degreased inside, turntable washed
Bathrooms
- Shower screen taken to optical clear; rainfall heads dismantled and soaked
- Bath, basin and WC descaled, with older sanitary ware kept on non-abrasive chemistry
- Grout scrubbed, any mould treated and flushed, silicone cleaned and blackened seals flagged for the landlord on the photo pack
- Chrome taps, shower arms, towel rails and radiator valves polished
- Extractor grille off and cleaned, fan blades dusted where they can be reached
- Mirror cabinet wiped in and out, shelves cleared
- Floor washed into the corners, skirtings detailed, WC cistern, rim jets and base descaled
Bedrooms and living areas
- Original Barbican parquet dry-buffed and conditioned, never wet-mopped or steamed
- Barts Square porcelain mopped on neutral-pH chemistry, grout lines done separately
- Conversion timber floors and any original windows cleaned with care, runners and catches included
- Full-height glazing cleaned both faces, frames and tracks vacuumed out
- Board-marked concrete ceilings and service-core walls dusted on extending poles in Barbican flats
- Skirtings, architraves, door frames and door tops wiped; switches, sockets, thermostats and entryphone handsets cleaned
- Built-in wardrobes emptied, vacuumed and wiped, rails and runners cleared
- Radiators and AC grilles dusted, behind them where there is access
- Beds stripped and mattresses vacuumed both faces; carpets vacuumed on a slow pass, with hot-water extraction priced on top where the inventory asks for it
- Private balconies and high-walk terraces swept and their drains cleared
Throughout
- All internal glass, vision panels and screens taken to a streak-free finish
- Reachable light fittings dusted, bulbs checked and counted for hand-over
- Hallways and any internal stairs in duplex flats vacuumed, handrails wiped
- Rubbish and recycling cleared to the Corporation’s collection point, sorted to its standards
- A dated check-out photo pack sent to your email, ready to forward to your letting agent
A few of those terms come up again and again with tenants, so it helps to pin them down:
- Check-in inventory
- The report and photos taken when you moved in, recording the flat’s condition. Your check-out is judged against it, so it sets the standard your clean has to hit.
- Board-marked concrete
- The Barbican’s raw concrete finish, cast against timber boards so the grain shows. It holds dust and cooking film in its texture, which is why it gets poled and wiped rather than ignored as “just a ceiling”.
- Hot-water extraction
- Deep carpet cleaning that injects hot water and lifts it straight back out with the dirt, as opposed to the surface vacuum that comes in the base price. It is the method most inventories mean by “professionally cleaned” carpets. See our carpet cleaning page.
- Mandatory HMO licence
- The licence a landlord needs to let a home to five or more people from two or more households who share facilities. It is the only property licence the City of London runs.
What it costs to clean a flat in EC1A and EC2Y
Pricing is nudged up a little from our London baseline for these postcodes, because the stock is premium and because the Barbican and Barts Square jobs need specific pads and chemistry the teams have to carry. Every price below includes VAT, materials, travel within EC1A and EC2Y, and the 48-hour re-clean guarantee.
| Property type | From | Typical Aldersgate range |
|---|---|---|
| Studio | £176 | £176–£207 |
| 1-bedroom flat | £227 | £227–£260 |
| 2-bedroom flat | £263 | £263–£339 |
| 3-bedroom flat | £359 | £359–£425 |
| 4-bedroom tower or duplex | £445 | £445–£520 |
| Carpet hot-water extraction (per bedroom) | £36 | £36–£43 per room |
| Oven deep-clean only (single) | £77 | £77 single, £110 double |
By the hour, where a clean does not fit a fixed tier, it is £30 per cleaner. Carpets work out at £36 a bedroom, £43 a living room, or £115 for a whole two-bed flat. Ovens are £77 for a single, £110 for a double and £114 for a range. If you want carpet cleaning, a standalone oven cleaning, upholstery or removals added to a move-out booking, we put them on one invoice with a small multi-service discount rather than billing them apart.
What your inventory clerk flags first
We have sat with enough clerks working EC1A and EC2Y check-outs to know the order things get caught. The list below runs by how often an item is flagged, not by how serious it is:
- Oven door glass, including between the panes, and any grill-pan residue
- Extractor filter condition, baffle, mesh and charcoal, and grease run-down into the hood body
- Limescale on shower screens, rainfall heads, mixer cartridges and grout
- Silicone seals in wet rooms and around the kitchen sink
- Parquet and timber floors: standing-water marks, scuffs, any sign of steam cleaning
- Board-marked concrete ceilings and service-core walls in Barbican flats, for dust, cobwebs and cooking film
- Window track dust and seal condition, worst on the full-height Barts Square units
- Inside cupboards: kitchen bases, wardrobes, airing cupboards
- Fridge and freezer seals and any defrost water in the trays
- Washing-machine drawer mould and the rubber door seal
- Skirtings, door tops and radiator tops, on the eye-level dust test
- Entryphone handsets and intercom panels, missed often, always in view
- Balcony and high-walk drains clear, outdoor surfaces swept
- Bulb count, every fitting working on hand-over
- Rubbish and recycling gone to the right point, not left in the bin store
- Keys and fobs returned and accounted for on the inventory
None of these is difficult on its own. The trouble is that there are sixteen of them, plus the rest of the flat, and a tired self-clean the night before a move tends to stop at about number six.
End of tenancy, deep clean, or a regular visit
People mix these three up, then book the wrong one. They are not the same job, and only one of them is built to pass an inventory.

| Feature | Regular clean | Deep clean | End of tenancy |
|---|---|---|---|
| Booking basis | Weekly, fortnightly or monthly | One-off | One-off, tied to your move-out date |
| Inventory match | No | No | Yes, the 57-point checklist |
| Oven interior | Wipe only | Full degrease | Bare-metal degrease |
| Inside cupboards and wardrobes | Doors closed | Emptied and cleaned | Emptied, vacuumed, wiped |
| Limescale | Surface only | Full descale | Full descale, optical clear on glass |
| Re-clean guarantee | No | No | 48 hours |
| Photo pack for the agent | No | Optional | Included |
A deep clean is the right call mid-tenancy, when you want the flat reset but you are staying put. A regular domestic clean keeps it ticking over fortnightly. The end of tenancy clean is the only one written to a clerk’s report, with the guarantee and the photo pack behind it, and it is the one to book when the deposit is on the line.
Booking a clean around Smithfield and the Barbican
Booking is quick. The day itself takes a bit of planning because of access, which we sort with you in advance.
- Call 0333 555 2076 or email [email protected] with your address, check-out date, bedroom count and any add-ons.
- We send a fixed price in writing, usually within two working hours, with the 57-point checklist and the 48-hour guarantee written into the quote.
- You pick a slot. Same-day and next-day slots come up often, and weekends and bank holidays carry no surcharge.
- The team turns up with all the chemistry, pads, machines and poles. You provide nothing. Access by porter, concierge, the Barbican Estate Office goods lift or a lockbox all works, as long as we know which it is.
- On completion we send the dated photo pack for you to forward to your agent. If anything is flagged inside 48 hours, we come back and redo that item for nothing.
Plenty of moves around here pair a clean with other work, so these come up most:
- Deep cleaning for a mid-tenancy reset rather than a move
- Carpet cleaning by hot-water extraction for bedrooms and living rooms
- Upholstery cleaning for sofas, mattresses and armchairs
- Oven cleaning on its own, AGAs and range cookers included
- Window cleaning inside for any address, outside subject to the building’s access rules
- Removals, studio up to four-bed, across London
- After-builders cleaning for the refurbishment work around Barts Square and the wider Smithfield development, where the old market buildings are becoming the new London Museum
That London Museum point is worth a line. The old Museum of London at London Wall closed in 2022, and its new home is taking shape in the Victorian General Market and Poultry Market at West Smithfield, a few minutes from Aldersgate Street, with the first galleries due in 2026. It is a useful marker for where the ward is heading: a working corner of the City that keeps rebuilding around its old bones, the medieval gate, the brutalist estate, the market sheds, all of it still in use.
Questions Aldersgate tenants ask
How long does an end of tenancy clean take in an Aldersgate flat?
A studio or one-bed in London House or a Barts Square flat usually takes four to six hours with a two-person team. A three-bed on the Barbican Estate, or a duplex in Shakespeare Tower, can run seven to ten hours because the floor area and the concrete detailing add time. We stay until all 57 points are signed off, not until a clock says we should leave.
Do you clean the original parquet floors in Barbican flats?
Yes, and we treat them as the inventory item they are. The oak block parquet in most Barbican flats sits on bitumen, so it is dry-buffed and conditioned with a finish-safe product. We never wet-mop or steam it. If a previous tenant has already scuffed or lifted blocks, we photograph it before we start so you can settle that with your landlord rather than carry the blame.
Can you reach the upper floors of the towers with proper access?
Yes. We have cleaned flats high in Shakespeare Tower, Cromwell Tower and Lauderdale Tower. The goods lift is booked through the Barbican Estate Office and we arrange that slot before the day. Interior window cleaning is in the price; the external glazing on the towers is done by the estate’s own abseil contractor, not by us.
Is the 48-hour re-clean guarantee something my letting agent can rely on?
Yes. If the inventory clerk or your agent flags an item within 48 hours of us finishing, we come back and redo that item at no charge. The guarantee answers to the agent as well as to you, so forwarding our dated photo pack on hand-over is the quickest way to get the deposit released.
Do you clean the communal high walks and lobbies of the Barbican blocks?
No. The Barbican Estate Office looks after every communal area, from the podium high walks to the block lobbies. We clean the inside of your own flat and any private balcony or terrace named on your tenancy, and nothing past your front door.
Is carpet cleaning included or is it an extra?
It is an add-on. Vacuuming on a slow pass is part of the base price, but hot-water extraction is charged separately at £36 per bedroom, £43 per living room, or £115 for a whole two-bed flat. If your inventory names professional carpet cleaning at check-out, book the extraction so the wording is matched.
Can you take a booking at short notice near a month-end?
Often, yes. Same-day and next-day slots around Aldersgate come up regularly, though the last week of any month fills first. Call 0333 555 2076 before 10am for a same-day attempt, or any time for the next day.
Which letting agents do you usually clean for around the Barbican?
We are on the books of 300+ letting agents across London, and around EC1A and EC2Y that includes the City-facing firms and the Barbican Estate Office’s own managing agents. Our 57-point list is written in the same language their clerks use, which is why it tends to pass first time.
Are you insured?
Yes. We hold £2 million public liability cover and £10 million employer’s liability cover. Certificates go over by email on request, which the bigger City managing agents often ask for before a clean.

What happens if the landlord disputes the standard of the clean?
We return inside 48 hours to redo whatever was flagged. If it still goes to adjudication through a deposit scheme such as TDS, DPS or mydeposits, our dated photo pack is accepted as evidence and usually settles the cleaning point in the tenant’s favour.
Do you clean Barts Square and Bartholomew Close new-build flats any differently?
Yes, mainly in chemistry and pads. The flats in Dominion House, Vicary House and Abernethy House have engineered-stone worktops that need pH-neutral products, polished porcelain floors that want a micro-fibre pad rather than anything abrasive, and handleless kitchens where dust works into the push-release runners. Our teams carry that kit as standard.
Can you handle an AGA or a range cooker?
Yes. An AGA clean is £130 because the enamel and cast iron need their own approved chemistry and a slow hand. Range cookers are £114 for a 90cm and £115 for 110cm and above. All three are quoted on top of the flat price, not hidden inside it.
Do you work weekends and bank holidays at the same rate?
Yes. Saturdays, Sundays and bank holidays carry no surcharge. A lot of City move-outs land on a Friday or a Saturday, so the weekend rate matters more here than people expect.
Will you take the rubbish away when you finish?
We clear normal household rubbish and recycling to the Corporation’s collection point for your block. Big items, like a sofa or a fridge that the next tenant will not want, go through our removals service for a set fee rather than being left in the bin store.
How far ahead should I book an Aldersgate clean?
Forty-eight hours is comfortable for a weekday slot. For the final week of a month, which is always the busiest, give us about a week. We still take same-day work when a slot is open, so it is always worth a call.
What payment methods do you take, and when?
Bank transfer, credit and debit card, and Apple or Google Pay. Payment is due on completion, once you have seen the flat and the photo pack, never up front.
Ready to book, or just want a price? Call 0333 555 2076 or email [email protected] with your Aldersgate address, bedroom count and check-out date. We confirm a fixed price within two working hours, hold you a slot, and send the 57-point checklist in writing before the day. The 48-hour re-clean guarantee starts the moment we hand the keys back.
