The Heron end of tenancy cleaning, sorted

The inventory clerk at The Heron turns to face the window before they look at anything else. With Barbican daylight flooding a high-floor apartment, the floor-to-ceiling glass is the surface that gives a tenant away, and hard-water bloom on it is the building’s most reliable deduction. So an end of tenancy clean here, from Monster Cleaning Ltd, is built around glass, chrome, stone and integrated appliances rather than skirting and carpet. A two-bed at The Heron is £243 and a studio £156, on a 57-point agent-approved checklist with a 48-hour re-clean guarantee, and £30 per hour per cleaner on a part job. Ring 0333 555 2076 for a price in three minutes.

Last updated June 2026. We cover The Heron on Silk Street and the surrounding City streets in EC2Y, from EC2Y 9AA. This page sits inside the City directory at End of Tenancy Cleaning City of London.

How the check-in report quietly decides your deposit

Start with the mechanism, because hardly anyone does, and it is the whole game. When you moved into your apartment at The Heron, a clerk walked it and wrote a report describing every surface, photographed on day one when the glass was spotless and the stone floor still had its factory polish. The pack recorded the flat as clear and clean, because the place had just been turned around to let-standard. At check-out a clerk walks it again and sets the new state next to the old state, in daylight, line by line. Anything materially worse than the check-in entry, past fair wear and tear, is chargeable against your deposit. You are marked against a recorded professional standard, which is why a tidy flat and a free weekend rarely get you there in a building finished to this spec.

Almost nobody loses a deposit in a tower like this on damage. The flats are young, the fittings are good, and tenants here tend to look after them. Money comes off for one reason: the hand-back finish did not match the itemised inventory, and in a glass apartment that inventory is unusually easy to mark against. A tide-line on a shower screen, a cloudy film along the bottom of a window, a splashback wiped while greasy so it dried smeared, an integrated oven that looks clean from the front and is brown across the back wall. None of that is damage. All of it is deductible, because the inventory says the surface was clear and now it is not.

The money is not small. City rents make these deposits worth arguing over, and the agent is on the hook for protecting one that sits in a scheme, so the inspection is genuinely careful. The clerk does not grade effort; they photograph the surface, set the shot beside the check-in picture, and write a line. Cleaning is the most disputed deposit category year after year, and the one a proper clean settles, because it turns on evidence rather than opinion.

Two things sit behind this in law. A landlord cannot make professional cleaning a contractual condition, so nobody can force you to book us. The deposit itself has to be protected in a government-backed scheme, and the government’s deposit-protection guidance sets out where the fair-wear line falls. A flat handed back not professionally clean, when it was let professionally clean, is a defensible deduction, and a dated professional clean is what answers it.

The daylight problem nobody sees coming

One thing makes The Heron different from almost every property we clean. The check-out is a concierge handover in a glass building, with the Barbican’s open water and terraces right outside, which means the clerk has far more clean daylight to inspect by than in any street-level flat. Streaks that pass unnoticed under a ceiling lamp are obvious here. Floor-to-ceiling glazing, a glass shower screen, gloss handle-less kitchen fronts and a polished stone floor all show every mark in that light, and the clerk turns deliberately to face the window to catch them.

So we clean to the light, not to a finish that only looks done in a dim hallway. The full-height window glass is taken to a streak-free finish on the inside, and the stone is buffed rather than left damp and cloudy. On a high floor the window is the single surface the inventory clerk is most likely to photograph, so it is the one we finish to the highest standard. None of this is clever work. It is patient, surface-by-surface work in the clerk’s order, done in good light.

Streaks that pass unnoticed under a ceiling lamp are obvious here.

What Thames Water does to a glass apartment

The City sits in London’s hard-water zone, and that one fact causes more borderline check-outs at The Heron than anything else we see. The supply is Thames Water, which runs hard across the capital, roughly 260 to 290 milligrams of calcium carbonate per litre. On a tower where most vertical surfaces are glass, that mineral content dries to a white haze a kitchen spray will not touch. Tenants scrub it, the haze stays, and they assume the glass is just old. It is not old. It is scaled, and it needs a proper descaling pass.

The wet room is where it lands hardest. A glass shower screen on hard water collects a dried tide-line low down and a spray-haze across the face, and a wipe that leaves a film when it dries is exactly the finish a clerk photographs. We take the screen, the taps, the showerhead and the tile grout back to clear with a real scale remover and physical effort, then dry and buff the chrome so nothing returns a bloom by the afternoon walk-through. The basin, the bath where there is one, the WC and any brushed fittings get the same treatment. The standard is simple: nothing should show a water mark when the clerk turns it to the light.

The same scale builds in the kitchen, on the mixer tap and the sink, and gets the same descaling pass. Where a fitting or a run of grout is genuinely past saving in a longer let, we photograph its state before we start, so the clerk cannot bill you for wear that was already there at check-in. That dated photo has settled more disputes than any argument has.

What a hand-back clean covers, surface by surface

End of tenancy is the full reset that gets a flat back to let-standard so a clerk signs it off, not a maintenance tidy. Everything below is included in the price for a standard apartment at The Heron, weighted toward the surfaces a glass tower gets marked on, and the whole job runs to a 57-point agent-approved checklist the team works through before the flat is handed back.

The kitchen takes most of the time, because handle-less gloss units and integrated appliances hide grease in exactly the places a clerk checks. The integrated oven is taken apart as far as it is designed to come, the door glass split so the brown film between the panels comes out, and the back wall and roof of the cavity cleared rather than just the front wiped. The integrated fridge-freezer, dishwasher and washer-dryer are cleaned inside, seals and drawers included, and eased out on their runners so the sides and floor behind them are done. The splashback, hob, extractor canopy and filter are degreased, the gloss fronts cleaned at the push points, and the sink and chrome descaled clear.

The bathroom or wet room is the second hard area, and the work there is mostly the descaling already described, taken methodically through every fitting. Glass screens and any enclosure get the full descaling pass, tiling and grout are cleaned and the silicone lines wiped back, and mirrors, any mirrored cabinet and the extractor vent are done before the floor is finished last.

Open-plan living space and bedrooms in these apartments are mostly hard floor, built-in storage and glass. Engineered or stone flooring is cleaned to the correct method rather than over-wetted, and built-in and walk-in wardrobes are cleaned inside, rails, shelving and the tops of units included. Skirting, floor edges, internal doors and frames, switches and sockets are wiped, radiators and convector grilles done, and the slats of any fitted blinds dusted, because that dust shows against the daylight. Then everything else a clerk can run a finger or eye along: internal glazing and any glass balustrade both faces, light fittings and vents, the tops of doors, and any utility or heat-interface-unit cupboard. Hard floors are finished last so nothing is walked back over.

One tower, and the City around it

The Heron is one building, and it is worth being precise rather than pretending it is a neighbourhood. It is a residential tower at 5 Moor Lane and Silk Street, EC2Y, in the Cripplegate ward of the City of London, designed by David Walker Architects and finished in September 2013: thirty-six storeys, 284 apartments from studios up to penthouses, an eight-storey atrium through the middle, a 24-hour concierge. It rises out of the Milton Court redevelopment, the lower part of which is the Guildhall School of Music and Drama’s Milton Court, a 625-seat concert hall and a theatre, so there is a working performing-arts venue directly beneath the flats. The stock is uniform in a way most areas are not: glazed, integrated-appliance, hard-floor apartments to a single high specification, let mostly to City professionals and as corporate or pied-a-terre flats. There is no period stock inside The Heron and we are not going to pretend otherwise.

The wider EC2Y context is the Barbican Estate next door, a different animal again. Chamberlin, Powell and Bon built it between 1965 and 1976, roughly 2,014 flats and around 4,000 residents across the terraces and three towers, and those towers, Cromwell, Lauderdale and Shakespeare, the last 44 storeys and once the tallest residential building in Europe, are concrete brutalist rather than glazed. The terrace blocks, Defoe House, Ben Jonson House and the rest, carry their own fitted detail. We clean the Barbican flats to the same inventory discipline, but the surfaces are board-marked concrete, parquet and original joinery rather than the gloss and glass of The Heron, so the method shifts to suit. The Barbican Centre, the City’s own arts centre, sits in the middle of the estate.

Access at The Heron is the easy part for once. Moorgate is a few minutes’ walk, with the Circle, Hammersmith & City, Metropolitan, Northern and Elizabeth lines plus National Rail, and Barbican station on the Circle, Hammersmith & City and Metropolitan lines is closer still. Our cleaners come in by Tube, which on a Square Mile job is far simpler than driving into the congestion-charge zone and looking for a bay on Moor Lane or Silk Street, where the on-street parking is metered and tightly controlled. We sort the concierge sign-in and the service-lift slot with the Silk Street front desk in advance, so the team arrives, signs in and goes straight up. For tenants in the adjoining towers and terraces we also cover the Barbican estate, and the City core around Moorgate, St Paul’s and Ludgate Hill.

What it costs, and the sum the deposit makes for you

The Heron runs at our standard City pricing, set out below, and there is no premium loaded onto the building despite the spec. The full tiers are in the table, with kit, products and travel into the Square Mile included. Those are flat prices agreed before we start, not a day rate that creeps, and part jobs or a top-up billed by time run at £30 per hour per cleaner. We would rather win the work than pad the quote.

Oven deep-cleaning is already included in the end of tenancy price; as a standalone it is £77 for a single oven, £110 for a double and £114 for a 90cm range cooker. Carpet shampoo is an add-on only where a flat has it, which most at The Heron do not, at £36 a bedroom, £43 a living room, or £115 for the whole carpeted area of a two-bed. Those figures assume a flat in normal lived-in shape. A long corporate let with heavy wear, or somewhere not deep-cleaned in years, costs more, and we say so on the phone rather than after, with no surprise lines on the invoice.

Run the sum the way the deposit makes you. A two-bed clean at £243 to protect a deposit running well into the thousands on City rents is not really a decision. Every booking at The Heron carries a 48-hour re-clean guarantee: if the clerk flags any cleanliness issue inside 48 hours, we come back and put it right free, as long as you tell us inside that window and the flat is in the state we left it. Our pass rate across the agents we work with sits near 97%, and the guarantee is the safety net under it. We are on the books of 300+ letting agents, and that work has helped tenants recover £1.2m in deposits that would otherwise have gone on cleaning deductions.

A high-floor one-bed, earlier this year

“I had a one-year tenancy on a high-floor one-bed at The Heron looking straight over the Barbican, and the flat genuinely was not dirty when I left. The one thing that nearly cost me was the glass. Hard water had left a bloom right across the floor-to-ceiling glazing and a tide-mark down the wet-room screen, and nothing I had under the sink touched it. Monster came in on the Tuesday before my Thursday concierge check-out, descaled the lot and finished the windows, and the clerk did the inspection facing the daylight on purpose and signed it off with no glass note at all. Full deposit back. As a single person juggling a finance job and a move, paying someone to deal with the one hard thing was easily worth it.”
Daniel, The Heron EC2Y, February 2026

That is the pattern in a tower like this: a flat barely dirty, a finish that fails only under daylight, and a clerk who inspects into the light on purpose. The clean cost a fraction of what was at stake. What turned it was the descaling and the dated photo set that went out with the invoice, the part most do-it-yourself check-outs never have when the agent pushes back.

Booking it, the concierge, and the month-end pinch

The City clusters its check-outs at month-end, so the day-before slots go first. Book early. The process is short and we keep it that way.

1. Ring 0333 555 2076. Price in about three minutes. Give us the apartment size at The Heron, your concierge check-out date and any known problem areas, and mention anything the check-in pack recorded as clean or as new.
2. We book you in, ideally the day before check-out with a buffer, and arrange the concierge sign-in and service-lift slot with the Silk Street front desk. Allow 7 to 10 days for an end-of-month slot, 3 to 5 days mid-month.
3. Flat empty when we arrive. Furniture out, belongings gone, rubbish cleared. We also do removals if you want the move and the clean on one booking, which helps when the loading bay and the lift have to be booked anyway.
4. The team works the 57-point checklist and finishes the glass, the wet room and the floors last so nothing is disturbed before the inspection.
5. Photo proof at the end. Every room, before and after, with a dated itemised invoice. Anything the clerk flags inside 48 hours, we come back and fix free.

Access here is genuinely the easy part, which is rare for us. The lift and concierge are sorted in advance, the flat is usually already empty, and the cleaners arrive by Tube. Confirm the handover slot and how we get in, whether that is concierge collection, a key safe or an agent drop-off, and the rest runs itself.

Which clean is which, and the rest of the work

A move-out at The Heron sometimes pulls in more than the core clean, and because the stock is glass and integrated appliances the add-ons that suit it are not the usual ones. An oven cleaning service covers the integrated appliance on its own if that is all the agent flagged, a window cleaning service handles the internal full-height glazing, and carpet cleaning is there for the rare apartment that has carpet or a fabric sofa to deal with.

Check-in inventory report

The pack the clerk writes and photographs on day one describing every surface. It is the benchmark your check-out is judged against, which is why we clean to it and not to a generic idea of “clean”.

End of tenancy clean

Built to pass that inventory and get a deposit back, against a concierge handover, with the flat empty and the 48-hour guarantee on it, at £30 an hour where billed by time.

Deep clean

A deep clean resets a flat you are keeping, with no inventory to hit, also from £30 an hour.

Regular domestic clean

A regular domestic clean is ongoing upkeep, weekly or fortnightly, from £22 an hour.

If your agent has asked for an end of tenancy or check-out clean, a deep clean is not the same product and a clerk will treat it differently. Book the end of tenancy one.

Questions we get asked

How much is an end of tenancy clean at The Heron?

A studio is £156, a one-bed £207 and a two-bed £243, which is where most apartments at The Heron sit, with a three-bed £339 and a four-bed £425. Those are flat prices for a flat in normal lived-in shape, with kit, products and travel into the Square Mile included, and part jobs billed by time run at £30 per hour per cleaner. The Heron is central and high-spec, but the figure is our standard City rate, with no premium loaded onto the building.

Why does the glass keep looking cloudy after I have cleaned it?

Because it is scaled, not dirty. The City sits in a hard-water zone supplied by Thames Water, and on floor-to-ceiling glazing and a shower screen that mineral content dries to a white bloom an ordinary spray will not lift. It needs a proper descaling pass and a buff dry, which is the single thing tenants at The Heron most often hand back wrong, because the glazing faces the daylight off the Barbican lakes and the clerk inspects into it.

Do you clean inside the integrated appliances?

Yes. The integrated oven is taken apart as far as it is designed to come, including the door glass and the back and roof of the cavity rather than the front alone, because a clerk checks behind the panel. The fridge-freezer, dishwasher and washer-dryer are cleaned inside, seals and drawers included, and eased out on their runners so the sides and floor are done. A handle-less gloss kitchen also hides grease at the push points, so those are degreased.

Can you work around the concierge desk and the lift booking?

Yes, and we sort it before the day. We arrange the sign-in and a service-lift slot with the front desk on Silk Street in advance, so the team arrives, signs in at concierge and goes straight up. The loading bay and lift booking are the part of a tower move-out that trips people up, so we plan the timing around your slot. Our cleaners come in by Tube rather than driving into the congestion-charge zone.

Which letting agents do you clean to the standard of at The Heron?

We clean to inventory-clerk standard rather than to one agent’s house style, so the bar is the same whoever manages your apartment. The Heron and the surrounding City and Barbican lettings are handled largely through the corporate and prime agents that work the Square Mile, JLL, Knight Frank and Frank Harris among them, and their clerks check to a detailed schedule of condition. We are on the books of 300+ letting agents across our patch.

Is my flat at The Heron covered by a City licensing scheme?

No. The local authority is the City of London Corporation, which runs the Square Mile rather than a London borough, and it does not operate a selective or additional licensing scheme, so there is no licence to satisfy at your hand-back. What governs the check-out is your tenancy agreement and the inventory the clerk holds, not a council rule.

Does the Renters’ Rights Act 2025 change my deposit position?

Not the cleaning side. The Renters’ Rights Act 2025 went live on 1 May 2026, ending fixed terms and Section 21 no-fault evictions, and existing assured shorthold tenancies converted to periodic ones. Your deposit still sits in a government-backed scheme, the cap is unchanged, and a clean below the check-in standard can still be charged for. The real effect in the City is timing: corporate and pied-a-terre lets turn over more often and less predictably, so the slot you want is harder to get late on.

My apartment has stone or engineered floors, not carpet. Does that change the price?

No, the band price stands. Carpet shampoo is only an add-on where a flat actually has carpet, and most apartments at The Heron are hard floor. We clean stone and engineered boards to the correct method for the floor rather than over-wetting them, and finish them last so nothing is walked back over before the clerk arrives.

What does the 48-hour re-clean guarantee actually cover?

It covers anything on the 57-point agent-approved checklist that the inventory clerk marks as not clean within 48 hours of us finishing. We come back and re-do that item free, as long as nobody has moved in and the flat is in the state we left it. It does not cover damage or wear that is not a cleaning fault. That guarantee is part of why we hold a 97% first-time pass rate across the agents we work with.

What if I disagree with a proposed deduction?

Your deposit is held in a government-backed scheme with a free dispute service, and the decision turns on evidence: the inventory, the check-in photos, the check-out report and any cleaning receipt. A dated, itemised professional clean is the strongest single document you can submit, which is why we itemise. The deposit schemes and Shelter set out the steps.

How do I get a price for my clean at The Heron?
