End of tenancy cleaning right across Canonbury Square

The terraces on Canonbury Square were laid out from 1805, and almost every one of them is now a flat. We clean end-of-tenancy flats across the square and the streets feeding off it, from Compton Terrace down to Alwyne Villas, with a fixed price quoted on the phone and a re-clean if the inventory clerk finds fault. A studio starts at £156 and a two-bed conversion at £243, both held to the same 57-point check an Islington agent expects. Call 0333 555 2076 for a quote inside the hour, any day of the week.

This page is about the square itself and the listed Georgian stock around it, not the wider Canonbury fringe. If your flat sits out toward the New River villas or the Highbury edge, the Canonbury edge page fits better. The parent end of tenancy cleaning in Islington hub covers the borough as a whole. Postcodes we reach from here: N1 2, N1 1, N5 1.

What the square actually is

Henry Leroux started building the north-west range in 1805, on a plot he leased from the Marquess of Northampton. Then in 1812 the New North Road turnpike, the road we now call Canonbury Road, was cut straight through the middle and split the square into an east side and a west side. That accident of road-building is why the two halves never quite match, and why a clerk reading an inventory on the west side sees slightly different detailing from one working a flat on the east. Both sides are listed. Both sides were carved into flats decades ago.

Two writers fix the square in most people’s heads. George Orwell took the top floor at 27b from 1944, stayed until 1947, and there is a blue plaque on the house to prove it. Evelyn Waugh had lived at 17a between 1928 and 1930, though his flat carries no plaque, which surprises people who assume the more famous tenant always gets the disc. The Compton Arms, the small pub Orwell drank in and later wrote up as his ideal local, still trades a short walk off the square.

The grandest building on the square is not a house at all anymore. Northampton Lodge, built between 1807 and 1810, holds the Estorick Collection of Modern Italian Art, a small gallery of Futurist and figurative work that has been open to the public since 1998. The lodge itself had a chequered run before that, a private home until the First World War, then an artificial flower factory for half a century, then the office where the architect Colin St John Wilson drew up the new British Library. Just east of the gardens stands Canonbury Tower, a brick tower put up between 1509 and 1532 and once lived in by Francis Bacon. None of that changes a cleaning checklist. It does tell you the kind of building you are handing back, and the kind of standard the people inspecting it carry in their heads.

A flat that looks fine to you can still lose money on the report.

Most of what we clean here is a conversion of one of those early-1800s townhouses. First floor through to attic. Deep plaster cornices, a ceiling rose in the main rooms, shutter boxes folded into the window reveals, original boards under whatever floor covering the landlord laid later, and a bathroom squeezed into what was once a dressing room or the servants’ end of the house. Every one of those features is a thing a clerk can mark. Plaster catches dust you cannot see from standing height. Shutters fold dirt into the hinge. Old glass shows every smear in low winter light off the garden.

Where the deductions hide in a listed flat

Listed status is the whole game on this square. A flat that looks fine to you can still lose money on the report. You cannot rip out an old sash and drop in a uPVC unit, so the windows you hand back are usually the windows that went in two centuries ago, repaired rather than replaced. That means the cleaning has to be gentle and it has to be thorough at the same time, which is the awkward bit. We use pH-neutral solution on painted timber, lint-free cloths on old glass, and we keep abrasive pads well away from brass handles, finger plates and door knockers. A scratched original fitting is a repair bill, not a cleaning note, and that is a far worse conversation to have with an agent.

The conservation designation here is the New River conservation area, named after the 17th-century channel that still threads through Canonbury Grove and past Willow Bridge Road on its way down from Hertfordshire. The protection is why the frontages, the railings and the fanlights all survive in their original form. For a tenant moving out it means one practical thing. The features a clerk inspects are old, they are delicate, and they were never designed to be wiped down in five minutes.

Across hundreds of N1 jobs the same traps come up. Here is where the money actually goes on a listed conversion, before we get to the line-by-line checklist further down.

Cornice and ceiling rose

Deep Georgian plaster holds a grey line of dust along every moulding. It is invisible at eye level and obvious to a clerk standing under it with a torch. We brush it out with soft heads rather than dragging a cloth across the relief.

Shutter boxes

Folding shutters trap years of grime in the hinge and along the top slat. We open them out, clean the slats one by one, and check the box recess most tenants forget exists.

Window horns and meeting rails

The joints on an old sliding sash gather dirt that a quick pass over the glass never reaches. These are a standard inspection point and a standard fail.

Brass in the wet rooms

A bathroom built into a former dressing room often keeps period brassware. Limescale dulls it, but a scouring pad ruins it, so the work is patient rather than quick.

There is a winter-light problem here that catches people out. The flats facing the central garden get low, raking sun through the old glass from about November, and that flat light shows up every smear and every wipe mark a summer clean would hide. We finish glass with a dry lint-free cloth for exactly that reason, because a streak you cannot see in July is the first thing a clerk sees on a bright January morning with the trees bare.

The other thing worth saying plainly. Communal garden rights come with several of these flats, and the access door, its glass and its threshold get inspected the same as anything inside. People forget the garden door because they rarely use it. Clerks do not forget it.

The licensing position as it stands

Canonbury ward is not in Islington’s selective licensing scheme, and that is worth getting right because the borough has been changing the map. Selective licensing, which makes a landlord get a licence for an ordinary private let whatever its size, currently covers three wards: Finsbury Park, Hillrise and Tollington. It has run in those three since May 2024. On 23 October 2025 the council’s Executive resolved to extend selective licensing to seven more wards, Barnsbury, Caledonian, Tufnell Park, Mildmay, Highbury, Junction and Laycock, taking the total to ten. Canonbury was not on either list.

So a single-household flat on Canonbury Square does not need a selective licence. A flat-share is a different matter. Islington runs a borough-wide additional HMO licensing scheme covering homes let to three or four people who are not one household and who share facilities, and it reaches certain section 257 cases too, meaning houses converted into self-contained flats where most of those flats are rented out and the original conversion never met the building rules of its day. A lot of these listed terraces were split exactly that way, so section 257 is not academic here. The renewed designation runs for five years from 1 February 2026. You can read the rules and the public register on propertylicensing.islington.gov.uk, and the council sets out which wards fall under which scheme on its own property licensing pages.

Why does any of this matter to a tenant trying to get a deposit back? Because it tells you who has been keeping an eye on the property. A licensed HMO has had a management standard applied to it, and the agent running the check-out tends to inspect to a tighter brief as a result. A licence does not protect your deposit. A clean that meets the inventory does. The two things sit side by side, and a poor clean loses money whatever the licence status of the flat.

The Renters Rights Act and your deposit

The Renters’ Rights Act 2025 got Royal Assent on 27 October 2025 and you can read the chapter itself on legislation.gov.uk; the wider statute book sits at legislation.gov.uk. It ends fixed-term assured shorthold tenancies and rolls everyone onto periodic tenancies, scraps section 21 no-fault eviction, and bans rent bidding. For a tenant on Canonbury Square the headline change is the move to periodic tenancies, which means your move-out date is no longer pinned to a fixed term and a check-out can land at shorter notice than it used to.

What the Act did not change is the deposit machinery. Your money still sits in one of three government-backed schemes, and the burden of proving a cleaning deduction is fair still rests on the landlord, not on you. The three schemes are the Tenancy Deposit Scheme, the DPS and mydeposits. Each runs a free adjudication service if you and the agent fall out over a cleaning charge.

That is where a professional clean earns its keep. If the property goes back in genuinely inventory-ready condition and a landlord still tries to dock the deposit for cleaning, the adjudicator wants evidence, and “it did not look clean” is not evidence against a photographed, checklisted hand-over. For independent guidance on the process, Citizens Advice and Shelter both set out where you stand and what counts as fair wear and tear. The borough rent context is on the ONS local housing dashboard, which put the average Islington private rent at £2,811 a month in April 2026 and the average house price at £679,000, both above the London figure and both a reminder of what these deposits are worth.

Streets we cover around Canonbury Square

Our regular Canonbury round sits tight around the square and the listed stock on the streets off it. We are out here most weeks, so a same-week slot is usually doable.

• Canonbury Square and Canonbury Place
• Compton Terrace, Compton Avenue and Compton Road
• Alwyne Villas, Alwyne Road and Alwyne Place
• Canonbury Road, Canonbury Lane and Canonbury Park North and South
• Canonbury Grove and Willow Bridge Road, along the New River line
• Northampton Park, Halton Road and River Place
• Canonbury Tower and the streets behind it
• The Upper Street end and the Highbury Corner side of the ward

Parking is the worst part of working here, and we will say so to your face. The whole area is a controlled zone, bays fill by mid-morning, and a van cannot just sit outside a listed terrace all day. If your flat is near Canonbury station we will often come in on the train instead, because the Overground runs straight to it. That station, by the way, sits on the renamed Mildmay line now, the old North London Line, with the Windrush line calling there as well and step-free access to all four platforms.

What the 57-point clean covers

The 57-point checklist is built from years of working with N1 letting agents, and it is matched to what their clerks actually write up. It is the same sheet we sign off on every flat, with extra care reserved for the period features this square is full of. Here is the work, room by room.

Kitchen

• Oven degreased inside, racks soaked, door glass split and cleaned between the panes
• Hob, extractor canopy and filter degreased; a disposable filter is replaced
• Fridge and freezer emptied, defrosted, washed inside and out, seals detailed
• Dishwasher run on a service cycle, filter cleaned, door seal wiped
• Washing machine drawer pulled and cleaned, drum run hot and empty
• Cabinet interiors and fronts wiped, handles polished, hinges checked
• Worktops descaled, splashback grout brushed, sealant checked for mould
• Sink and taps descaled, brass finished without abrasion
• Floor washed, edges and corners done by hand

Bathroom

• Limescale taken off taps, shower head, screen and tiling
• Toilet descaled in the bowl, behind the cistern and around the base
• Bath, basin and tray polished, sealant scrubbed and mould treated
• Mirrors, glass and chrome finished streak-free
• Extractor vent dusted and wiped
• Period brassware cleaned by hand, no pads
• Floor washed and hand-detailed at the edges
• Towel rail and radiator cleaned front and back

Bedrooms and living rooms

• Cornicing and ceiling roses dusted with soft brushes
• Shutters opened out, slats and hinges cleaned, the box recess checked
• Sash windows cleaned inside, horns and meeting rails included
• Picture rails and dado rails wiped the full run
• Deep skirting profiles hand-cleaned, including behind radiators
• Original boards swept and mopped or buffed to suit the finish
• Carpet vacuumed with edge tools; extraction quoted on request
• Wardrobes, drawers and cabinets wiped inside and out
• Brass door furniture polished, the underside of the rose included
• Switches, sockets and thermostats wiped

Throughout the flat

• Internal doors wiped both sides, top edges included
• Light fittings and shades dusted
• Vents and extractor grilles cleaned
• Cobwebs cleared from cornice corners and window reveals
• Communal threshold and any private stair to the flat detailed
• Final walk-through against the 57-point sheet, with photos kept for 90 days

Carpets, soft furnishings and glass beyond the internal sashes are priced on their own. We can bring in carpet cleaning, upholstery cleaning, dedicated oven cleaning and window cleaning on the same visit, and there is hard floor cleaning for the original boards when a buff is not enough.

What it costs on the square

Our end-of-tenancy prices are fixed once we know the bedroom count, the condition and any add-ons, and they are the full price, not a teaser. The figures below are the standard tiers. Listed conversions sometimes take longer than a plain flat of the same size, because of the shutters and the plaster, but the price is agreed up front on the call so there is no surprise at the end.

For context on what is at stake against those numbers. A two-bed on the square can carry a deposit of £4,000 to £6,500, so a £243 clean that protects the lot is not the part of the move to economise on. We have helped tenants recover £1.2m in deposits over the years, money that would otherwise have gone on cleaning deductions, and we are on the books of 300+ letting agents who see our work and our sign-off sheets week in week out.

What an Islington clerk flags first

Inventory clerks on the square are usually instructed by the bigger Islington names, the sort of agents who let these flats and who run check-outs to a tight brief. From hundreds of N1 reports, this is the order things tend to get flagged.

1. Limescale on chrome and brass taps, shower heads and screens
2. Grease under the extractor canopy and behind the hob
3. Oven door glass not cleaned between the panes
4. Dust banked in cornice profiles and ceiling rose detail
5. Window horns, meeting rails and shutter hinges left untouched
6. Skirting tops, especially the run behind a radiator
7. Carpet edges and the strip under a bed not vacuumed
8. Sealant blackening around the bath rim
9. Internal door tops, hinges and architrave dust
10. Fridge seal mould and freezer ice residue
11. Communal garden door glass, frame and threshold
12. Loft hatch surround and the floor of a storage cupboard

None of these is hard on its own. The problem is volume. A clerk does not need to find a disaster, only enough small misses to justify a half-day cleaning charge, and on a flat full of period detail there are simply more places for a small miss to hide. That is the whole reason the checklist exists.

One more thing the better agents do here is bring in an independent clerk rather than inspect themselves, which raises the bar again. An independent clerk has no stake in waving the flat through and gets paid to find things, so the report comes back longer and the photos come back closer. We clean to that standard by default, because a flat that satisfies an independent clerk satisfies everyone, and the 48-hour re-clean means that if we and the clerk read a moulding differently, we are back on the doorstep to settle it rather than arguing over a photo.

End of tenancy against a deep clean

People mix these up, so here is the plain version. An end-of-tenancy clean is for an empty flat with a deposit on the line, signed off against the 57-point sheet and backed by the 48-hour re-clean. A deep clean is a reset for a flat you are staying in, thorough but not tied to an inventory. A regular clean is the weekly or fortnightly upkeep. The table sorts out what each one actually includes.

If furniture is still in the flat on the day, we cannot run it as a true end-of-tenancy clean, because the clerk inspects behind and under everything. In that case we either quote a deep clean instead, or we line up our removals team to clear the flat first and clean straight after. For a flat coming out of building work, after builders cleaning is the right starting point before the end-of-tenancy pass.

A few words the trade uses

If this is your first managed check-out, the language can be off-putting. Here is what the main terms mean in practice.

Check-in inventory

The report and photos made when you moved in, recording the condition of everything. The check-out is judged against it, so wear that was already there at the start is not your problem to clean off at the end.

Inventory clerk

The independent person who walks the empty flat at the end and writes the condition report the agent and landlord act on.

Selective licence

A licence a landlord needs for an ordinary private let in a designated ward. Canonbury is not a designated ward, so a normal flat here does not need one, though the borough’s map of wards keeps changing.

Additional HMO licence

A licence for a house or flat shared by three or four people who are not one household. Islington runs this borough-wide, so a flat-share on the square does fall under it.

Fair wear and tear

The gradual ageing of paint, carpet and fittings through normal living. A landlord cannot dock your deposit for it, and the deposit scheme adjudicators apply it when a charge is disputed.

Booking and keys

Booking is short. The five steps below are the whole of it.

1. Call 0333 555 2076, email [email protected] or use the form, and tell us the bedroom count, the condition and your check-out date.
2. We send a fixed quote inside the hour, weekdays and weekends alike.
3. You confirm by reply and we hold a slot, usually within 48 hours.
4. The team arrives with all equipment and chemistry and works the 57-point sheet. You do not need to be there.
5. We send photo sign-off on completion. If the agent flags anything inside 48 hours, we come back free.

Keys are easy to sort. We can collect from your agent or a key safe and drop them back once the sign-off photos are done, which suits the short-notice check-outs the new periodic tenancies are throwing up. Saturday slots in N1 book about a week ahead, so a weekday morning is the quickest way in if your date is tight.

Questions tenants on the square ask

How much is end of tenancy cleaning on Canonbury Square?

A studio starts at £156, a one-bed at £207, a two-bed at £243 and a three-bed at £339. The price is fixed on the call once we know the bedroom count, the condition and any add-ons.

Do you guarantee I get my deposit back?

We guarantee the clean, not the agent’s decision. If the inventory clerk flags any cleaning issue within 48 hours we return free. Our first-time pass rate is 97% across N1.

Can you handle a Grade II listed flat?

Yes, most of the square is listed. We use pH-neutral solution on painted timber, no abrasives on brass or old glass, and we work around the period features rather than over them.

How do you clean original sash windows and shutters?

Internal glass, horns and meeting rails are cleaned by hand with lint-free cloths. Shutters are opened out and done slat by slat, with the box recess checked. External upper-floor glass is quoted separately.

Does a flat on Canonbury Square need a selective licence?

No. Canonbury is not in Islington’s selective licensing scheme, which currently covers Finsbury Park, Hillrise and Tollington, with seven more wards added by the October 2025 decision. A single-household flat here needs no selective licence.

What if my flat is a shared HMO?

Islington runs a borough-wide additional HMO licensing scheme for homes shared by three or four people who are not one household, renewed for five years from 1 February 2026. It also catches certain section 257 converted-flat cases common in these terraces.

How long does a two-bed conversion take?

A two-bed period flat usually takes a three-person team six to nine hours, longer than a plain flat of the same size because of the shutters, the plaster and the brass. A four-bed house can run to twelve hours.

Do I need to be there during the clean?

No. We can collect keys from your agent or a key safe and return them after the sign-off photos. That suits the shorter-notice check-outs the new periodic tenancies are creating.

Can you clean the communal garden door and hallway?

We clean the garden access door, its glass and threshold, the inside of the flat door and the area just outside it. Full communal stair cleaning is a separate quote, usually agreed with the block manager or freeholder.

Is carpet cleaning part of the price?

Vacuuming with edge tools is included. Steam extraction is a paid add-on at £36 per bedroom, £43 for a living room or £115 for a whole two-bed.

Are you insured?

Yes. We carry public liability and employer’s liability cover, and a certificate goes over on request before the booking is confirmed.

What happens if the flat fails the inventory check?

Send us the clerk’s report within 48 hours and we return at no charge to put right the flagged items. We have used this re-clean guarantee on the square and we honour it every time.

Can you do a clean at short notice?

Often yes, especially on a weekday morning, because we run a regular Canonbury round. Saturday slots in N1 tend to book about a week ahead.

Where can I get independent advice on a deposit dispute?

Citizens Advice and Shelter both explain your rights and what counts as fair wear and tear. The scheme holding your money, the Tenancy Deposit Scheme, the DPS or mydeposits, also runs free adjudication.
