End of tenancy cleaning for One Blackfriars homes

Most of our One Blackfriars work is post-2018 luxury hand-back: a Mandarin-Oriental-adjacent flat on floors 6 through 32, a corporate-let tenant going home to Singapore or Riyadh on four weeks’ notice, and a Knight Frank Bankside clerk booked in 48 hours after the keys come back. The flat has a Quooker boiling tap, a Gaggenau induction hob, Miele appliances throughout, a smart-home tablet on the wall, and roughly thirty square metres of curved floor-to-ceiling glass facing the river. We clean it to get the deposit back. The booking line is 0333 555 2076.

Why deposits get deducted at One Blackfriars

The single biggest reason a One Blackfriars deposit shrinks is cleaning. The Tenancy Deposit Scheme’s annual reports have put cleaning at the top of dispute reasons every year for the last decade, and that pattern is sharper at the top of the Bankside towers than it is in a Peckham conversion. A flat here lets at £4,200 to £8,000 a month depending on the floor, the orientation and whether it carries the Mandarin Oriental service component. The deposit is therefore five weeks of rent, in plain numbers somewhere between £4,800 and £9,200. The clerk arriving on check-out has been briefed by the agent, the agent has been briefed by the freeholder’s lettings team, and the freeholder wants the flat re-let inside a fortnight.

The deductions then stack in a recognisable order. Mineral deposit around the Quooker spout, because the tap dispenses boiling water and the calcium scales fast. Grease film inside the Miele extractor canopy that the previous tenant never thought about. Dust along the bottom track where the curved glazing meets the inner door frame. Smudges on the brushed-nickel pull-handle of the wardrobe. Coffee residue inside the Miele built-in espresso machine, which most tenants do not realise has a removable brew unit. Marble bathroom counter water-rings. Hoover trails missed where the floor changes from oak engineered board to bathroom porcelain. The clerk’s torch picks out each of those in turn.

Renters’ Rights Act 2025

The Renters’ Rights Act 2025 took out the assured shorthold fixed term and replaced it with a periodic-only structure, which on One Blackfriars practically means a corporate let can end on two months’ notice from the tenant from any month onward. That does not change the cleaning standard at hand-back. The Act left the deposit cap untouched at five weeks of rent under £50,000 a year and six weeks above, and the deposit must still be protected with one of three government-approved schemes within thirty days of receipt. On rents that sit between £4,200 and £8,000 a month the deposit money is real, and the dispute process at Tenancy Deposit Scheme and mydeposits tends to favour whichever side has the timestamped photographs and the dated invoice. We invoice with our company number on the document, send twelve dated pre- and post-clean photos per room within twenty-four hours of finishing, and keep a copy on file for five years.

Southwark Council licensing

Southwark operates a selective licensing scheme covering nineteen wards across the borough, brought in from November 2023 and running until February 2027. The borough’s licensing pages confirm London Bridge & West Bermondsey ward as a covered area, and the same officers look at the SE1 9 stretch where Blackfriars Bridge meets the south bank. Practically that means landlords running One Blackfriars lets hold a selective licence on top of any HMO licence that applies, and check-out reports get read carefully by the council if a dispute lands at deposit-scheme adjudication. Cleaning failures get cited in those reports verbatim. Holding back the receipts for an EOT clean done by a registered company is not optional if you want the deposit money returned in full.

Bankside-specific feature: the curved-glazing window cleaning regime

One Blackfriars carries its name for a reason. Simpson Haugh designed the fifty-storey tower with full-height curved glazing that bulges outward on the river-facing elevations, which is what gave it the nickname the Vase. From the inside that translates to roughly five metres of glass per principal room with a four-degree curve that catches every fingerprint and every smear. The building’s facade-access team handles the outside on a rope-access cycle three times a year. The inside is the tenant’s problem, and on a hand-back it is firmly the cleaner’s problem.

We clean the inside of curved glazing with a non-streak microfibre on a telescopic head and finish each panel with a dry e-cloth pass to lift the haze. Glass cleaner is squeegeed from the top down. The bottom-track aluminium between the glazing and the engineered oak floor is run with a soft brush and then a vacuum nozzle, because that is where the clerk’s first finger goes. We never use a household glass spray with ammonia on the curved units because the gasket sealant can mark, and the spray drift hazes the brushed-nickel window hardware that frames each panel. We descale the Quooker and the kettle separately with a weak descaler appropriate to the metal. We do not name the chemical agent because the brand we use varies across the team’s vans; what matters is the result, which is a streak-free panel that the clerk can photograph without losing a deduction line to glazing dust.

“I had eight days between a Mandarin Oriental hotel-suite-style flat on the 27th floor and the Knight Frank clerk’s appointment. The flat had been corporate-let for fourteen months to a Singapore bank’s MD, lots of dinner parties, the Miele coffee machine was caked inside, and the curved glazing in the river-facing reception had not had a proper wipe in months. Monster came on a Tuesday with three cleaners, finished the whole 1,180-square-foot flat in nine hours, and the clerk knocked off £140 for a chip in the marble worktop and signed off the rest. £6,650 deposit back out of £7,200. The cleaner who turned up actually knew not to spray the curved glass with ammonia, which was new to me.” – Andrea L., 27th floor One Blackfriars, March 2026

Coverage – streets and zones we work

Most of our SE1 9 work sits in the immediate Blackfriars-Bankside cluster between the bridge and the Tate. The buildings we do most often around here:

• One Blackfriars itself, the fifty-storey tower on the south side of Blackfriars Bridge. One- and two-bed flats on the residential floors, with the Mandarin Oriental hotel occupying the lower section. The principal stock is luxury one-beds at 600-700 square feet and two-beds at 1,000-1,300 square feet, with a handful of three-bed sky apartments on the upper floors.
• NEO Bankside, the four pavilions behind Tate Modern on Holland Street and Sumner Street. Mostly two- and three-bed flats, polished concrete floors, floor-to-ceiling glass, all post-2012 stock.
• Bankside Lofts, the Manhattan Loft conversion on Hopton Street. 120 lofts with double-height ceilings, exposed brick, hardwood floors.
• The South Bank Tower on Upper Ground, the remodelled King’s Reach Tower. Tall, glassy, and full of the same Gaggenau-Miele finish package as One Blackfriars.
• Sea Containers House on Upper Ground, residential and Mondrian hotel mixed.
• The Hopton Street and Holland Street streetscape generally, where post-2010 infill blocks have replaced older warehouse stock.

If you are letting a Bankside flat south of the river between Blackfriars and Southwark Bridges, we cover the whole stretch. The 2018-onward stock is the busiest part of our work in this postcode. Period stock here is rare and we do not pretend it is the dominant archetype – this is a luxury new-build belt.

What’s included

The work is the 57-point agent-approved checklist used by Knight Frank Bankside, Hamptons More London, JLL Riverside South and Frank Harris on Bankside hand-backs. Every line below runs the same way whether the flat is a studio at £156 or a four-bed at £425. The price changes; the work doesn’t.

Kitchen

Inside the Gaggenau oven, including the back wall, the door glass between the panes (we separate it where the manufacturer says do not, because dust always settles there), the trim, the seal, and the racks washed in the sink. Pyrolytic ovens still get a manual scrub because the self-clean function leaves ash. Miele extractor canopy and the filter cassette, lifted, degreased and refitted. Induction hob, including the seams around each cooking zone where crumbs collect. Splashback. Inside every cupboard and drawer, including the integrated bin housing. Miele coffee machine: we pull the brew unit, rinse, descale the line, wipe the drip tray and the bean hopper. Quooker boiling tap: descaled with a metal-appropriate solution, polished. Dishwasher seal and filter. Integrated fridge inside and out including the door gasket. Sink, polished. Floor edge-to-edge.

Bathrooms

Walk-in shower glass, descaled both sides to the hinge. Showerhead, hose, every surface of the brushed-nickel fittings. Marble or stone counter and basin, wiped with a stone-safe cleaner and dried streak-free. Loo inside the rim, behind the cistern, and at the hinge bolts. Mirror without streaks. Extractor cover wiped. Tile grout. Floor. Heated towel rail descaled where needed. If the flat has a separate WC, the same list runs again.

Bedrooms and living areas

Skirtings, the tops of every door frame, the radiators front and back, all switch plates, the smart-home thermostat panel wiped with a damp microfibre (not soaked), the smart-lock fronts. Wardrobes inside and out including the brushed-nickel handles. Mirrored sliding doors descaled and polished. The inside of the curved floor-to-ceiling glazing, panel by panel, with the bottom track vacuumed. Hoovering on a pattern that does not leave drag-marks on the engineered oak floor.

Throughout

All internal doors both sides. Door handles. Light fittings dusted including the recessed downlights and the pendant in the principal reception. The internal lift call button if the flat has a private lift lobby. Skirtings at floor level vacuumed and wiped. Air-conditioning grilles wiped. The flat’s hallway floor finished last so the team walks out clean.

What it costs

Pricing for One Blackfriars sits at our standard EOT tier. The building’s concierge process, the service-lift booking and the higher inspection standard get factored into the team size and the slot length, but the headline number is the same as the rest of our SE1 work outside the very top-tier blocks. Flat rates for an empty flat in average condition below; lived-in, pet-occupied or post-corporate-let work gets quoted on inspection.

Hourly rate for partial work or unusual scope is £30 per cleaner. Carpet shampoo where the flat carries a wool runner or a bedroom rug runs at £36 per bedroom, £43 for a living room, £115 for a whole two-bed flat. Oven add-ons (rare on these jobs because the oven is in the EOT scope already, but useful for a 90cm range or a second integrated oven outside the standard package): £77 single, £110 double, £114 for a 90cm range. No travel charge inside the M25.

Booking the service lift through One Blackfriars’s concierge takes a 48-hour lead time on most weeks. We make that call once you confirm. The concierge needs our company name, the flat number, the team size and the access window.

What your agent will actually check

Knight Frank Bankside, Hamptons More London, JLL Riverside South and Frank Harris all run inventory check-outs through specialist clerks. The clerks work to a script. Across the One Blackfriars stock the consistent inspection points, roughly in order:

1. The Miele extractor canopy interior and the filter cassette – lifted out, photographed both sides.
2. The Quooker spout and the area beneath it on the worktop, where mineral haze accumulates fast.
3. Inside the Miele coffee machine, brew unit out, drip tray and bean-hopper interior.
4. The curved floor-to-ceiling glass, panel by panel, in raking light from the river-facing windows. Smudges show up immediately.
5. The bottom track where the glazing meets the engineered oak floor – dust and grit collect there.
6. The Gaggenau hob seams between zones.
7. The dishwasher filter and the rubber door seal.
8. Marble bathroom counter for water-rings.
9. Inside every wardrobe rail, across the top shelf.
10. The smart-home thermostat panel and the smart-lock fronts for fingerprint marks.
11. The shower drain hair trap.
12. The integrated fridge gasket and the freezer drawer runners.
13. Skirtings throughout, especially at the threshold where engineered oak meets bathroom porcelain.

If the team has been through the flat properly, every one of those points has been done before the clerk arrives. The cleaners carry their own torches and a checklist.

EOT vs Deep vs Regular

The three packages do different jobs. Quick table so you can pick the right one.

If you are on a corporate let with the agent organising the check-out, EOT is the package you need. If you have just bought into One Blackfriars and want the flat reset before you move in, deep clean is the right call. Regular is for keeping it nice while you live in it.

How booking works

1. You phone 0333 555 2076 or email [email protected] with the postcode, the bedroom count, the floor number, the date the agent has booked the check-out, and the access route (concierge with key, key safe, agent-held keys). We reply same working day.
2. We confirm the slot, the team size, the service-lift booking and the add-ons. One Blackfriars’s concierge requires a 48-hour service-lift booking; we handle that call.
3. You leave the flat empty by 8am on the day. If furniture is part of a furnished let and stays for the next tenant, we work around it.
4. The team works the 57-point checklist top-to-bottom. Average two-bed at One Blackfriars takes three cleaners about six to seven hours. Three-beds run seven to nine. The Mandarin Oriental hotel-floor flats sometimes need longer because the bathroom counts are higher.
5. We send you the photo set the same evening. If the inventory clerk flags anything within seventy-two hours of finish, we come back and put it right at no charge. That is the 48-hour re-clean guarantee, and it is the reason our 97% first-time pass rate is what it is.

Frequently Asked Questions

What does end of tenancy cleaning cost at One Blackfriars?

Studio £156, one-bed £207, two-bed £243, three-bed £339, four-bed £425. Hourly partial work runs at £30 per cleaner. Carpet shampoo and 90cm-range oven jobs are priced as separate add-ons.

Do you cover the Mandarin Oriental hotel floors?

The Mandarin Oriental hotel operation handles its own housekeeping for the hotel suites. We work the privately let residential flats on the upper floors above the hotel, and the principal-residence stock. If you live in a serviced apartment booked through the hotel, the hotel’s housekeeping team is your route.

Can you handle the curved floor-to-ceiling glazing on the inside?

Yes. We clean the inside of curved glazing panel by panel with a non-ammonia glass cleaner on a telescopic squeegee, finish with a dry e-cloth pass to lift haze, and vacuum the bottom track between the glazing and the engineered oak floor. The exterior is the building’s facade-access team’s responsibility on a rope-access cycle.

What about the Miele coffee machine and the Quooker boiling tap?

Both are in scope. We pull the brew unit from the Miele machine, descale the line, wipe the drip tray and the bean hopper. The Quooker spout and the area beneath it get descaled with a metal-appropriate solution and polished. We do not use harsh abrasive products on either piece.

How fast can you get to a One Blackfriars flat?

Same-week is normal. Same-day is sometimes possible for one-beds if you phone before 9am, but the bottleneck is the concierge service-lift booking, which takes 48 hours to confirm. For a two- or three-bed plan 5-7 days ahead.

What is the 48-hour re-clean guarantee?

If the inventory clerk flags any cleaning failure within 48 hours of our finish, we come back at no charge and put it right. We have had to use it on roughly three out of every hundred One Blackfriars jobs, which is where the 97% first-time pass rate comes from.

What does the 57-point agent-approved checklist cover?

The full list of inspection points the principal SE1 letting agents work to: kitchen interior including the Gaggenau hob and the Miele extractor and coffee machine, every bathroom from the shower glass to the heated towel rail, every bedroom and living area including the curved glazing, and the access points. We have built and refined the list across 300+ letting agents over twelve years.

Have you really recovered £1.2m in deposits for tenants?

Across the company since 2014, yes. £1.2m is the running total of deposit money that would otherwise have gone to deductions but came back to tenants on flats we cleaned. We audit the number internally each January from the dispute outcomes the deposit schemes confirm to us.

Is the water around One Blackfriars hard?

Very hard. Thames Water reports the SE1 supply zones at around 280-300 mg/l calcium carbonate, which is the upper end of the very-hard band. That is why mineral build-up on the Quooker, the kettle, the shower glass and the brushed-nickel bathroom fittings is the second-most-cited deduction reason in this postcode after general grime.

Do you bring your own equipment?

Yes. Hoover, mop, microfibre system, glass squeegees on telescopic heads for the curved glazing, descalers appropriate to the metal underneath, stone-safe cleaner for the marble bathroom counters, and full PPE. We supply everything; the flat supplies access.

Will the work pass a Knight Frank Bankside check-out?

97% of the time on the first attempt. The remaining 3% get the re-clean callback inside 48 hours and pass on the second visit. The clerks at the Bankside office know our work; we have been on the One Blackfriars list since the building opened in 2018.

What about pets, smells, and corporate-let wear?

Corporate lets where the tenant has been overseas a lot tend to be in good shape. Lets where there has been a dog or a cat get quoted on inspection: pet hair on engineered oak is straightforward, hair worked into a wool bedroom runner is a separate carpet job at £36. Smell treatment is a separate visit and we will tell you straight whether it will work before you book it.

Do you do oven cleaning on a Gaggenau as a standalone?

Yes. Single Gaggenau oven £77, double £110, 90cm range £114. The oven is included in the EOT package headline price; we only charge the add-on when it is outside the standard scope or you have booked oven-only.

Are you insured for work in a high-rise residential block?

Yes. Public liability £5m and employer’s liability £10m, with documentation available before the visit if the building manager requires it on file. The One Blackfriars concierge has had us on file since 2019.

Do you accept commercial bookings from the agents directly?

Yes. We invoice the principal Bankside letting agents on thirty-day terms with our company number on the document. A meaningful share of our One Blackfriars work comes in through Knight Frank Bankside and JLL Riverside South direct rather than through tenants.

What if the flat is part of a serviced-apartment let?

If the flat is operated as part of the Mandarin Oriental’s serviced operation, their housekeeping team handles it. If the flat is privately owned and let on a residential AST or corporate let, the EOT clean is yours to book and we are the right team. Phone us to confirm which side of that line your flat sits on.

Where can I read more about deposit disputes?

The TDS page at tenancydepositscheme.com sets out the dispute steps clearly. The mydeposits adjudication notes cover the documentary side. Shelter’s tenancy deposit guidance covers the legal framework if you want a charity-side summary.
