From canons to conversions: the Canonbury let
Canonbury Tower was built between roughly 1509 and 1532 by Prior William Bolton, who ran St Bartholomew’s Priory over in Smithfield and used the land out here as a country retreat. The name comes straight from that. Canonbury is “the canons’ bury”, the fortified manor house of the canons, granted to the priory back in 1253 and held until Henry’s men dissolved the monasteries in 1539. Most tenants who book us have walked past the Tower without clocking how old it is. It still stands just east of Canonbury Square, and Prior Bolton’s name survives two streets over on Prior Bolton Street.
None of that would matter for an end-of-tenancy clean, except that it shaped the housing. Canonbury filled in slowly, Georgian then early Victorian, and most of those big houses were later cut into flats. So when you hand back the keys here, the flat you are cleaning is usually a slice of a listed or near-listed building, with old fabric the inventory grades hard.
Canonbury Square is the obvious example, and the most telling. Henry Leroux started building the north-west range in 1805 on Marquess of Northampton land, and the square was fully occupied by 1826, which makes it one of the earliest in Islington. George Orwell rented a flat at number 27b from autumn 1944, having been bombed out of his last place, and finished Animal Farm and worked on Nineteen Eighty-Four while he lived there. Evelyn Waugh had been at 17a a decade and a half before him. Most of those houses are now flats, and most of those flats are lets, so the same rooms that produced two of the century’s better-known books now turn over on twelve-month tenancies and get inventoried like any other.
The stock is not all grand, mind. The square and the streets off it are period and listed. But the east of the area holds the Marquess Estate, a 1970s council scheme of around 1,200 homes that has since been heavily redeveloped, and there are post-war and modern infill blocks scattered through. A lot of our work sits between the two: a converted Victorian villa flat one day, a flat in a newer block off St Paul’s Road the next. The clean differs by the age of the fabric more than by the postcode.
That is the thread running through this page. We have cleaned end-of-tenancy flats across N1 for over a decade, and Canonbury has its own quirks. The stock is older than the borough average, the agents are stricter on it, and the deposits at stake are large because the rents are.
What a period-conversion clean actually involves
A clean in a 2015 block off St Paul’s Road and a clean in a converted 1830s house on Alwyne Villas are not the same job. The newer flat has flush surfaces, sealed units, a fitted kitchen built five years ago. The conversion has original sash windows with deep glazing bars, skirting a foot tall, picture rails, sometimes a cast-iron fireplace nobody has used, and floors that are either reclaimed boards or old parquet. Every one of those features is a place dust settles and a place the clerk looks.
Sash windows are the first headache. They have an upper and a lower pane that both slide, so there are tracks, beads, and a meeting rail in the middle that collects black grime you only see in daylight. We clean the glass inside, wipe the runners, and get the dust off the glazing bars without flooding the timber. We do not soak old window joinery, because water sitting on softwood that has been painted twenty times will lift the paint and the clerk will note it.
Then the floors. Parquet and old boards mark if you wet-mop them like a tiled kitchen. We dust-mop and use a barely damp cloth on a sealed wood floor, never a sopping one, because standing water gets into the joints between blocks and swells them. If a herringbone floor has lifted at one corner, that is wear, not dirty, and we will tell you so you can put it to the agent rather than scrub at it pointlessly.
Walls in these flats are often lime plaster under the modern emulsion, and the older the plaster the more it shows a smear. We dust them down and spot-clean marks. We will not scrub a wall hard enough to burnish it, because a shiny patch on a matt wall reads worse than the mark did. Light switches, sockets, picture rails, the tops of doors: all wiped. The cornice gets the cobwebs taken off with a soft head, gently, because Victorian plaster cornice chips.
Original features in the bathroom and the hearth need the same judgement. A converted flat may keep a cast-iron bath with a roll top, or original encaustic and Victorian floor tiles in the hall. Some keep a fireplace with a tiled surround and a cast-iron grate that has not had a fire in it for decades. Old tiles are not modern ceramic; the glaze is softer and the grout between them is porous, so we clean them with that in mind and do not take a hard abrasive to a tile that the inventory logged as original. A cast-iron bath cleans up well but marks if you use the wrong product on the enamel. We clean the grate and the surround as features to be presented, not stripped, because the clerk is checking they are there and intact, not gleaming like new.
It is detailed work. That is the point of booking a firm that does it daily rather than borrowing a friend’s steam mop.

Where deposits leak in a Canonbury flat
Deductions almost never come from the obvious places. People hoover the middle of the carpet and wipe the worktops. The money goes on the surfaces nobody thinks about until a clerk shines a torch on them.
The oven is the big one. In a flat let furnished, the cooker often came with the tenancy and has not been deep-cleaned in years, and “we never used it much” does not survive a check-out. Burnt-on grease on the door glass, racks gone brown, the grill pan, the rings: all gradeable. The extractor hood above it traps a film of grease that yellows the metal, and the filter behind the grille is frequently the single dirtiest item in the flat.
Limescale is the second. North London water is hard, and a period bathroom with an old basin, a cast-iron bath, or chrome taps from a 2018 refit will fur up round the spout and the plughole. Clerks photograph limescale because it photographs well. We acid-treat the affected metal and ceramic, then buff it, so the chrome comes back rather than staying cloudy.
After that it is the quiet list. Skirting behind where the sofa stood. The window tracks. Dust on top of the kitchen wall units where no tenant ever reaches. Door tops. The inside of the kitchen cupboards, which must be empty and wiped, crumbs and all. Behind the toilet. The seal round the shower tray, where pink mould grows in a week. None of these are difficult. There are just a lot of them, and the standard is “as the inventory found it”, which is higher than the standard you live to.
Radiators are an underrated one in these flats. Old column radiators and the gaps behind any panel radiator collect a surprising amount of dust, and a clerk who runs a hand down the back of one and comes away grey will write it up. Tall sash windows mean tall sills, and the dust on a first-floor sill that you never look at from inside is in plain view from the street and from the clerk’s camera. Then there are the bits unique to a furnished let. The underside of dining chairs, the back of a wardrobe that came with the flat, the dusty top of a tall bookcase that has stood against one wall since you moved in. A check-out compares every supplied item to its move-in photo, so anything the landlord provided is anything you are accountable for.
Get one of them wrong and the agent has grounds to hold part of the deposit while it gets sorted. That is the gap our 48-hour re-clean guarantee closes. If the clerk or the agent challenges anything we cleaned, we come back inside three days and put it right at no charge, which usually settles the matter before the deposit dispute even opens.
The licensing picture: Canonbury against its neighbours
This part trips up tenants and small landlords alike, so it is worth getting right. Islington runs two different licensing regimes, and Canonbury sits in one of them but not the other.
The borough-wide one is additional HMO licensing. Islington has operated it across the whole borough since 1 February 2021, and it catches houses in multiple occupation, which in plain terms means a property shared by enough unrelated people or certain converted buildings. A lot of Canonbury’s big houses cut into flats and shared rooms fall under it. If you rent a room in a shared Canonbury house, your landlord very probably needs a licence for it, and you can check the position on the council’s Islington property licensing pages.
The other regime is selective licensing, which covers all privately rented homes in named wards, shared or not. Here is the bit specific to this area. Islington’s selective scheme runs in just three wards, Finsbury Park, Tollington and Hillrise, and in October 2025 the council approved extending it to seven more, including neighbouring Barnsbury and Highbury, though that extension is not yet in force. Canonbury is on neither list. It is not one of the three live wards, and not one of the seven lined up for the extension either. So a self-contained flat here that is not an HMO sits outside selective licensing, unlike the Barnsbury flats up the road that are due to be pulled in once the extension starts.
Why does a cleaning firm care? Because licensing drags inventories with it. Where a property is licensed, the paperwork around it tends to be tighter, check-ins more thorough, condition logged in more detail at the start, so the end-of-tenancy bar is higher. We see cleaner-looking flats fail on a stricter check-out than on a casual one, and the licensing status is part of why a check-out is strict.
None of this changes what we clean. It changes how carefully the result gets graded, and that is worth knowing before you book.
What the inventory clerk checks on Canonbury Square
The check-out is a walk-round against the inventory taken when you moved in. The clerk works room by room, photographs everything, and grades each item against its move-in condition. On a period flat that is a long list, because there is more in the room.
In the kitchen they open the oven, lift the hob rings, pull out the grill, check behind and under the appliances if they move, open every cupboard and drawer, and run a finger along the top of the units. Splashback tiles and grout get looked at. The sink, the taps, the plughole, the bin recess. In an old kitchen they will also note the window above the sink, because that is where steam and grease meet and nobody cleans it.
In the bathroom they check the bath or shower tray, the seals, the grout, the taps and showerhead for limescale, the toilet inside and behind, the extractor fan grille, the mirror, and the floor where it meets the skirting. Period bathrooms with original tiling get extra attention on the grout lines.
In the living rooms and bedrooms it is floors, skirting, window glass and tracks, sills, radiators front and back, picture rails, the cornice, light fittings, switches and sockets, and the insides of any fitted wardrobes. They will move what moves and look behind it. The sash windows alone can take a clerk several minutes a room.
We clean to exactly that walk. Our teams work a 57-point checklist that the agents themselves recognise, so the supervisor is ticking off the same items the clerk will check, in the same order, before the clerk ever arrives. That is the whole reason we hold a 97% first-time pass rate on these flats. We have built the list around what gets flagged, not around what looks tidy.
The agent relationship helps here in a way tenants do not always see. We are on the books of 300+ letting agents across London, a good number of them the firms working Upper Street and the streets around the square, so we already know what a given agency’s clerks tend to mark hard. Some are fussy about oven door glass, some about limescale, some about the tops of skirting. Knowing the agent before we arrive means the team cleans for that clerk’s habits rather than to a generic idea of clean, and it is one more reason the flat passes the first time.
It also means we are honest about what is wear and tear rather than dirt. A scuffed sash cord or a faded board is age, not a cleaning failure, and the deposit schemes know the difference. If you do end up arguing a deduction, the deposit protection scheme runs a free dispute service that weighs the evidence on both sides, and a clean flat plus a clear inventory is most of your case.
We have built the list around what gets flagged, not around what looks tidy.
Carpets, ovens and the jobs we add on
The end-of-tenancy clean covers the flat top to bottom. Some jobs sit outside it because they need different kit, and on a period flat they come up often. We will tell you on the quote which ones your flat actually needs, rather than upselling the lot.
Carpets are the common add-on. A lot of Canonbury conversions have carpet in the bedrooms over old boards, and if it is stained or flattened a vacuum will not save it. Our carpet cleaning uses hot water extraction, which lifts ground-in dirt the inventory photo will otherwise catch, and it is worth doing where the move-in report logged the carpet as clean.
The oven is the other one people bolt on. A proper oven clean means taking out the racks and the removable parts, cleaning them apart from the oven, then doing the interior and the door glass so the burnt-on grease is gone rather than smeared. In a furnished let where the oven came with the flat, this is the single job most likely to save your deposit.
Upholstery is worth a thought if the sofa came with the tenancy. Our upholstery cleaning extracts the dust and grime out of the fabric, which matters when the inventory will compare the sofa to its move-in state. For the outside of the windows, which a check-out on an upper-floor flat can still note, our window cleaning team reach them with water-fed poles. And if a floor has gone past cleaning into needing a proper treatment, our floor cleaning covers hard floors that a standard clean cannot rescue.
Two more, while moving. If you want the help shifting boxes, we run a removals service, and if you are staying put and just want the place brought back rather than handed back, our domestic cleaning covers regular upkeep instead.
What it costs and how the quote works
We do not charge by the hour. An hourly clean gives the cleaner a reason to slow down and gives you a bill you cannot predict. We price the whole flat as a fixed job, based on its size, and the team stays until every room is done to the checklist.
Size means bedrooms and bathrooms, roughly. A studio off Canonbury Road is a smaller job than a three-bed maisonette on Alwyne Road, and the quote reflects that. Tell us the postcode, the number of bedrooms and bathrooms, and whether you want carpets or the oven adding, and we give you one number. That number does not move on the day unless the flat turns out to be very different from what you described, which is rare.
What you do not pay for: detergents, equipment, or a weekend surcharge. The team brings everything. We work seven days, and the Saturday or Sunday price is the same as the Tuesday price, which matters because tenancy end dates rarely fall on a weekday to suit you.
What the flat needs from you is simple. Electricity on, hot water running, and the fridge and freezer defrosted before we arrive, because a frozen-solid freezer cannot be cleaned and a wet one mid-defrost soaks everything below it. Clear out your belongings first too, so the team can reach the skirting, the cupboards, and behind the furniture that is going with you.
Set against the cost, the maths is straightforward. With Islington rents averaging around £2,763 a month, a deposit on a Canonbury flat is several thousand pounds tied up. A fixed-price clean that gets it back is cheap insurance, which is roughly why we have helped tenants recover £1.2m in deposits that would otherwise have disappeared into cleaning deductions over the years. Our end of tenancy service exists for exactly this handover.
Timing matters too, because the deposit clock is not yours to control. Once you and the landlord agree how much comes back, the deposit has to be returned within ten days, but a disputed deduction over cleaning can stall that for weeks while the scheme adjudicates. A flat that passes the check-out first time skips all of that. You agree the figure, the money comes back inside the timescale, and you are not chasing an agent through August over an oven you could have had cleaned for a fraction of what they want to withhold. That is the practical reason the clean pays for itself, beyond the headline saving.
Booking a clean around the Overground
Most of our Canonbury jobs are reached off the Overground rather than driven to. Canonbury station sits on the Mildmay and Windrush lines, with Highbury and Islington one stop down as the Windrush terminus. So the team can get to a flat off Wallace Road, or down towards the New River Walk, without a van having to park. The station has had four platforms since the East London line was extended north in 2011, and it runs a good frequency through the day. That is part of why so many Canonbury tenants are commuters, and why the lets here turn over to professionals on the move.
The geography sets the working day. The New River Walk threads through the middle of the area, a thin strip of water and planting that the old manor’s southern edge once followed. A lot of the period flats look onto it, or onto one of the garden squares. Over towards Upper Street you have Compton Terrace and the Grade I Union Chapel, now as much a music venue as a church, and the streets there are tight Georgian terraces with no off-street parking at all. A team carrying a carpet machine to a top-floor flat on one of those terraces is carrying it from wherever they could stop, which is part of why we plan the heavy jobs carefully.
Parking is the grumble here, and it is a real one. Much of Canonbury is controlled-parking zone, the streets around the square are tight, and a Saturday with the New River path busy and half of Upper Street out for the day makes a loading bay hard to find. We plan kit-heavy jobs, the ones with carpet machines, around that, and we will tell you straight if a particular street means the team arrives on foot from the station with the gear.
It rarely affects you. We give you an arrival window, the team turns up inside it, and the clean takes as long as the flat takes. Booking is a phone call. Tell us the date your tenancy ends, the postcode, and the size of the flat, and we will hold the slot. Same price seven days a week, so a Sunday checkout is no dearer than a midweek one.
If you are moving within the area, it helps to know the neighbours. We cover the same end-of-tenancy work in Highbury just up the line, across Barnsbury to the west, throughout Islington generally, around De Beauvoir Town to the south-east, and up at Newington Green. Whichever side of N1 you land on, the service is the same.
End of tenancy against a deep or regular clean
People mix these up, and booking the wrong one wastes money. They are different jobs with different aims.
A regular clean keeps a lived-in flat ticking over. A deep clean is a heavier one-off, good for spring or after building work, that gets into the parts a weekly clean skips. An end-of-tenancy clean is neither. It is a clean aimed at a specific document, the inventory, with the goal of returning the flat to its move-in condition so the deposit comes back. It covers the whole flat, empty, to a let standard, and it is graded against a report rather than against how you like your home kept.
The glossary below sorts the terms that come up most when tenants ring us, because half the confusion is just vocabulary.
- End-of-tenancy clean
- A full, top-to-bottom clean of an empty flat, priced per property, aimed at matching the move-in inventory so the deposit is returned. Backed here by our 48-hour re-clean guarantee.
- Check-out inventory
- The clerk’s report at the end of a tenancy, comparing the flat photo by photo against the check-in condition. The document your clean is judged against.
- Deposit protection scheme
- The government-approved scheme holding your deposit. A landlord must protect it within 30 days, and there are three approved schemes covering England and Wales.
- Additional HMO licensing
- Islington’s borough-wide licence for houses in multiple occupation, running since 2021. It covers many shared Canonbury conversions.
- Selective licensing
- A licence covering all private lets in named Islington wards. Canonbury is outside it. Neighbouring Barnsbury and Highbury are among seven wards the council approved adding in October 2025, an extension not yet in force.
- Wear and tear
- The fading and minor marking that comes from normal living. A landlord cannot deduct for it, only for damage or for dirt a clean should have removed.
One more thing worth saying plainly. The law around renting changed with the Renters’ Rights Act 2025, which reshapes how tenancies end, but the deposit basics still hold. Leave the flat clean to the inventory and the deposit comes back. That has not changed, and it is the one part of moving out you can fully control.
Questions Canonbury tenants ask
Do you clean period conversion flats differently from new-builds?
Yes. A converted Georgian or Victorian flat has original sash windows, old floors, lime plaster and tall skirting, all of which need careful handling rather than heavy scrubbing or soaking. We dust-mop sealed wood floors instead of wet-mopping them, clean sash tracks without flooding the timber, and spot-clean old plaster rather than burnishing it. The aim is to clean the old fabric to the inventory standard without marking it, which is a different job from a sealed-surface new-build.
Will my Canonbury flat need an HMO or selective licence?
It depends on the let. Shared Canonbury houses and many converted flats fall under Islington’s borough-wide additional HMO licensing, which has run since 2021. Canonbury ward is not in Islington’s selective licensing scheme, which currently runs only in Finsbury Park, Tollington and Hillrise, so a self-contained flat that is not an HMO sits outside selective licensing here. Neighbouring Barnsbury and Highbury are among seven wards the council approved adding in October 2025, but that extension is not yet in force. Check the exact position for an address on the council’s property licensing pages and confirm with your agent.
What does the clean cost and is it priced by the hour?
It is a fixed price for the whole flat, never by the hour, based on the number of bedrooms and bathrooms. Tell us the postcode and the size of the flat and we give you one number that does not change on the day. There is no weekend surcharge, so a Saturday or Sunday checkout costs the same as a midweek one, and detergents and equipment are included.
What happens if the inventory clerk fails the clean?
We come back. Our 48-hour re-clean guarantee means that if the clerk or the agent flags anything we cleaned, we return within three days and put it right at no charge. Because our teams work a 57-point agent-approved checklist, that rarely happens, which is how we hold a 97% first-time pass rate, but the guarantee is there so a single missed item never costs you the deposit.
Do I need to be there, and what does the flat need?
You do not have to be present, though many tenants drop the keys and let us in. The flat needs electricity on, hot water running, and the fridge and freezer defrosted, since a frozen freezer cannot be cleaned. Clear your belongings out first so the team can reach skirting, cupboards and the spaces behind furniture, and the clean covers everything else.
Can you clean carpets and the oven at the same visit?
Yes, and on a Canonbury conversion both are common add-ons. We bring hot water extraction for carpets and a full strip-down for the oven, including the racks and removable parts cleaned separately. Add them when you book and we fold them into the one fixed quote, so the whole handover is sorted in a single visit. You can also browse our carpet cleaning and oven cleaning pages for what each involves.
How quickly can you come, and do you work weekends?
We work seven days a week at the same price, and we can usually fit a Canonbury flat in at short notice around your tenancy end date. Call us with the date, the postcode and the number of rooms, and we will hold the slot. Booking is a phone call rather than a form, and you can reach us through the contact page.
