We have cleaned London rentals to inventory standard since 2014, and we read every check-out report that lands on our work. This is what the clerk actually opens, touches and photographs, why tenants lose deposit money on the same handful of items, and how to pass first time.
This is general information for London tenants, landlords and letting agents, not legal advice. For your specific tenancy, talk to Citizens Advice, Shelter or a solicitor.
The short version
- An inventory clerk is an independent professional who inspects the property at check-out and writes the report your deposit scheme reads if there is a dispute.
- London clerks are usually members of the Association of Independent Inventory Clerks (AIIC), which has set the standard since 1996.
- They compare the check-out against the check-in inventory you signed on move-in day. That signed report is the benchmark, not the clerk’s opinion.
- Cleaning is the single biggest cause of deposit deductions in England and Wales. It featured in 54% of the disputes the Tenancy Deposit Scheme adjudicated in the year to March 2025. The oven, the washing-machine seal, limescale, grout and carpets top the list.
- Typical deduction per item runs from about £40 for a quick wipe-down to £80–150 for a missed appliance, and £300 or more for a full re-clean of a 2-bed. Most of it is avoidable.
- What wins if a dispute happens: the original signed inventory, dated check-out photos, and a cleaning invoice on company-headed paper.
The good news first. More than 99% of tenancies end without a formal dispute at all. In the year to March 2025 only 1% of the 4.7 million protected deposits in England and Wales went to adjudication, around 46,950 cases (TDS Statistical Briefing 2024/25). The aim of this guide is to keep you in the 99%. If a check-out is coming up, our free check-out preparation checklist puts the weeks around moving day in order.
Who actually inspects the property at check-out?
An independent inventory clerk, hired by your landlord or letting agent. In London they are almost always a member of the Association of Independent Inventory Clerks, the AIIC, which has set the standard for the trade since 1996. Members carry professional indemnity and public liability insurance and follow the AIIC Code of Practice. The big London inventory firms that agents use are mostly AIIC-accredited.
The clerk is the third party in the room. They do not work for the landlord, they do not work for you, and they do not pocket anything extra for finding faults, despite the myth. They follow a checklist, take a lot of photos and compile a report. That report is what the deposit scheme (TDS, the DPS or mydeposits) reads if there is ever a dispute, and the adjudicator leans on it because the clerk is the only neutral party who had hands and eyes on the property.
You usually will not be there. Most clerks prefer it that way; it is their process, not a negotiation. You can often arrange a key handover, and we would. What you should not do is walk them round explaining things. They have heard it all and it does not help.
How a London check-out actually runs
A proper check-out takes 60 to 90 minutes for a 2-bed flat, sometimes two hours or more for a 3-bed house or anywhere with a lot of furniture. The clerk arrives with the original check-in report on a tablet. They work room by room, compare each item to the check-in entry, photograph anything that has changed, and type notes as they go. A London check-in report for a larger property can run to 40 or 50 pages: every socket, every light fitting, every scuff on every skirting board, each with a photo. The check-out sits alongside it, line by line.
The report has three columns. The check-in description. The check-out observation. And a suggested action, the clerk’s recommendation on whether a deduction is justified and who is liable. The clerk does not make the final call. The landlord does, and if you disagree, the deposit scheme’s adjudicator does. But that suggested action carries real weight, because adjudicators trust the professional body and the process behind it.
Turnaround is usually 24 to 72 hours. The report lands with landlord, agent and tenant at the same time. That is when you find out what has been flagged.
The room-by-room check-out checklist
After more than a decade and over 40,000 London properties cleaned, the pattern barely changes. Below is what clerks check, grouped the way they actually move through a home, with the items roughly in order of how often we see them flagged on reports coming back from the 300-plus London letting agents we work with. Clean to this and you clean to the standard that passes.
In the kitchen
The oven, inside and out. This is the single most common failure, and it is the first thing every clerk opens. The glass between the two door panes has to come apart and be cleaned on both faces; tenants almost never do this. Racks need a proper soak, not a wipe. The seal, the fan, the element and the roof of the cavity where grease drips up and carbonises all go on the report. A flagged oven in London typically costs £80 to £150 in deductions, which is roughly what a professional oven cleaning costs anyway. We use a non-caustic dip-tank for the removable parts, which is the finish clerks expect.
Extractor hood filter. The metal grease filter slides out and goes in a soak or the dishwasher. Most tenants have never touched it. The clerk pulls it and photographs the underside.
The washing-machine door seal. The rubber gasket around the drum. Live somewhere a year and there is a black mould ring under the lip. Every clerk opens it. Pull the seal back gently and you will see what they see. Typical deduction: £40 to £80.
The detergent drawer and its housing. The drawer pulls out completely. Almost nobody cleans the compartment behind it, where soap residue and hard-water scale build up. Clerks pull it and photograph the back.
Fridge and freezer seals. The rubber gaskets collect crumbs, spills and a sticky film. Every clerk pulls the door back to check. If the freezer has not been defrosted, that is an automatic flag, and it has to happen before we arrive; we cannot defrost a freezer inside an end-of-tenancy slot.
Behind and under the appliances. The fridge gets dragged out. So does the washing machine, and the dishwasher. Dust, crumbs and the odd forgotten coin behind them are all part of the check. In new-build flats with integrated appliances this is the single biggest gap in tenant-led cleans.
Inside cupboards and drawers. Every drawer pulls out, every cupboard opens, and the cupboard under the sink, often skipped, gets inspected. The tops of the wall units, which most tenants never see, get photographed from a stepladder.
In the bathroom
Limescale on taps, shower heads and screens. London water is hard to very hard in every borough. Thames Water’s network averages around 300 parts per million of calcium carbonate, and some areas run higher: Epping at 370ppm and High Barnet at 347ppm are among the hardest in the country, and even an inner-London postcode like E5 in Clapton sits around 348ppm (WaterHard.uk, 2025). Scale builds fast. The check-in photos almost always show bright chrome; at check-out the clerk photographs every tap, head and screen with scale on it. That is a cleaning issue, not fair wear and tear. Typical deduction: £40 to £80 for a descale.
Grout. White grout versus grey grout is often the line between a pass and a £100-plus deduction. It has to be scrubbed, not wiped. If your grout was white on move-in and is grey on move-out, that reads as cleaning. If the grout itself has broken down or gone mouldy inside the structure, that is a landlord maintenance issue, but you will need evidence to make that case.
Sealant around the bath, basin and shower. We do not re-seal at check-out, but clerks check the sealant for mould. Black and crumbling is a landlord issue. Salvageable but grimy is a cleaning issue. The line between the two gets argued.
Extractor fan cover. The bathroom fan cover pulls off and reveals a grey disc of felted dust. It gets photographed.
Bins, mirrors and glass. Inside and outside of the bin, especially the rim near the hinge. Mirrors and glass shelves for streaks. Limescale on a shower screen gets counted twice, once as scale and once as smeared glass.
Living rooms, bedrooms and hallways
Carpets. Vacuuming is not enough. London tenancy agreements often include an explicit clause asking for professional carpet cleaning with a receipt, and where that clause exists, not producing the receipt is close to an automatic deduction. Hot-water extraction at around 200°F is what we use and what agents expect. If you have had pets, it is non-negotiable. Our carpet cleaning goes in on the same visit.
Skirting boards and the tops of things. Dust settles, then goes sticky with airborne kitchen grease. Every horizontal top above head height is a specific check: door tops, picture rails, the lintels over interior doors, the ledge where a radiator meets the wall.
Behind the radiators. The backs collect a grey-brown fur that is visible from an angle even when the front looks clean. Clerks get behind them with a torch. A long radiator brush earns its keep here.
Light switches, sockets and fittings. Switches get touched thousands of times and pick up a dark halo round the toggle that looks like shading but wipes off with the right product. Socket plates collect dust on the top edge. Light fittings get checked for dust and dead flies.
Walls and ceilings. Surface scuffs that wipe off are cleaning. Nail holes, damaged plaster and marks from hung furniture are damage. Mould on a wall is a damp problem, which is the landlord’s, but you need to document it so the deduction does not land on you.
Window frames, sills and tracks. The sliding tracks on sash and casement windows collect a nasty black deposit: dust, plus traffic pollution, plus condensation residue. London air makes it worse than most cities. The clerk runs a finger along the track.
Door handles, finger plates and hinges. Fingerprints on the plates, dust on the hinges. Both get photographed and both are easy to miss in a self-clean.
The whole property
The smell. This one is not on the printed checklist but it is on every report. “Property has a lingering smell of cooking, smoke or pets at check-out” is a quiet deposit-killer: it is vague, hard to disprove, and it often tips a borderline report into a deduction. Pet tenancies under the Renters’ Rights Act make it matter more, and we cover that in our Renters’ Rights Act 2025 post.
What a flagged item actually costs
Deductions are not random. They track the cost of putting one item right. Here is the rough London going rate we see on reports, item by item.
| What gets flagged | Typical London deduction |
|---|---|
| Quick surface wipe-down missed (one room) | around £40 |
| Oven left dirty | £80–150 |
| Washing-machine seal and drawer | £40–80 |
| Bathroom limescale and descale | £40–80 |
| Grout left grey | £100+ |
| Carpets, no professional clean / no receipt | £60–150 per room |
| Full re-clean of a neglected 2-bed | £300+ |
Set those against the cost of doing it once, properly, and the maths usually favours a professional clean with a receipt. The receipt is half the value; it is your evidence.
Why London agents are stricter than most
Three reasons.
Deposits are bigger. The average protected deposit in England and Wales is now £1,175, the highest on record (TDS, 2024/25). In London it is far higher, commonly £1,250 to £1,650 in the outer boroughs and £1,850 to £2,300 in central ones, because the deposit is capped at five weeks’ rent and London rents are high. More money at stake means more scrutiny on both sides, and the clerk in the middle has to write a report that stands up when everyone is cross.
The market turns over fast. London has some of the shortest average tenancies in the country. A flat that changes hands every 18 months needs a sharper inventory trail than one lived in for five years, and agents who manage big portfolios insist on professional-standard check-outs because their income depends on the place being re-lettable straight away.
The agents compete harder. In a borough like Kensington and Chelsea or Camden a dozen agents chase the same landlords. “We keep your property to a higher standard” is part of the pitch, and that standard gets enforced at check-out, on the tenant’s deposit.
It does vary. Without naming names, since we work with 300-plus agents and would like to keep all of them, Zone 1 agents tend to be stricter than Zone 3 to 6, premium-positioned agents stricter than volume ones, and agents with dedicated property managers stricter than those where the sales desk handles check-outs. None of it is unreasonable. It is a spectrum, and professional cleaning is calibrated to the strict end of it.
The three kinds of London inventory clerk
After working with hundreds of them, clerks fall into three buckets.
The reasonable professional, most of them. They follow the AIIC code, they are fair, they note what genuinely needs noting and they let normal wear and tear pass. They have seen thousands of homes and they know what a well-cleaned one looks like. Do the job properly and they mark it properly.
The overzealous one, a minority. Often newer, or working somewhere that measures output by issues identified. They flag things a more experienced clerk would let go: a small mark on a skirting that is arguably wear and tear, a carpet compression clearly from furniture that has been there since check-in. The upside is that these reports often get challenged and lose, because the code is clear that fair wear and tear is not deductible.
The rushed one, rare. Worked all morning, running late, report due by five. If the place looks clean at a glance they tick the box. You can scrape through a check-out like this without a full clean. It is a dice roll and we would never plan around it, because almost every other time you get one of the first two.
You have no way of knowing which you will get. So the strategy is simple: clean to the standard that passes the overzealous one, and by definition you pass the other two.
What the clerk cannot actually do
Worth knowing your footing.
They cannot make the final deduction. They only recommend. The landlord claims, you respond, and if there is no agreement the adjudicator decides. The report is evidence, not a verdict.
They cannot charge you for cleaning as a contract term. The Tenant Fees Act 2019 still bans landlords from requiring tenants to pay for professional cleaning, and the Renters’ Rights Act 2025 does not change that. You are free to clean it yourself, as long as it reaches a professional standard. A clerk noting “would benefit from a professional clean” is a suggestion, not an instruction. Charging a prohibited fee can land a landlord with a penalty of up to £5,000 (GOV.UK, Tenant Fees Act 2019 guidance).
They cannot penalise fair wear and tear. A worn patch on a hallway carpet after three years. A faded strip of paint where the sofa stood. These are not deductible, and a professional clerk records them as wear, not damage.
They cannot demand entry before you hand back the keys. The tenancy runs until surrender is complete. Give notice in writing, coordinate the check-out, and do not hand over the keys until you are happy with the clean.
The evidence that wins if the report goes against you
If the check-out flags something unfairly, or pins something on you that was not your doing, you can challenge it for free through your deposit scheme’s Alternative Dispute Resolution (ADR) service. Plenty of disputes never reach that stage. TDS reports that a large share now settle through early resolution before a formal adjudication is needed.
Here is the honest position on who wins, because the internet is full of comforting numbers that do not hold up. Adjudication is not weighted in the tenant’s favour or the landlord’s. It is weighted toward whoever brings better evidence. Landlords tend to succeed when they hold a signed check-in inventory backed by dated photos. Tenants tend to succeed when the landlord has no signed inventory, relies on estimates instead of invoices, or claims for plain wear and tear. The adjudicator reads files all day and is moved by documents, not by tone.
The deposit dispute is won or lost on move-in day, not move-out day. The signed check-in inventory is the benchmark everything else is measured against. If it is thorough and photographic, both sides know where they stand. If it is thin, the tenant is usually in the stronger position.
What the adjudicator wants to see from you:
- The signed check-in inventory with its photos.
- Your own dated check-out photos, taken the morning of the final clean, before the keys go back.
- The cleaning invoice on company-headed paper, listing the address, date and scope.
- Any correspondence with the landlord or agent about the alleged issue, including emails and written replies to the proposed deductions.
- If carpets are in play, a separate carpet-cleaning receipt that names hot-water extraction.
What does not work: your word that “it was clean”, vague claims with no photos, a receipt from a mate with a vacuum, or general anger at the landlord. None of it moves an adjudicator.
How we hit this standard every time
We run a 57-point, inventory-matched checklist. Every item in the room-by-room list above is on it. Every property gets photographed before and after, room by room, and that pack comes to you as your evidence for the check-out. We work with more than 300 London letting agents and we know which are strict on which items, so cleaners get briefed before the job. Our first-time pass rate at agent inspections sits around 97%.
If a clerk flags anything within 48 hours of our clean, we come back and fix it free. You do not argue with the landlord; you send us the report. That 48-hour re-clean guarantee is why we can quote flat, fixed packages, studio from £156, 1-bed from £207, 2-bed from £243, 3-bed from £339, without padding the price as insurance.
Want the full scope? It is on our end-of-tenancy page. Want a price for your place? Ring 0333 555 2076 or use the contact page. A quote takes about three minutes on the phone, and we will tell you straight if your timeline is unrealistic.
Frequently asked questions
What does an inventory clerk check at a London check-out?
The clerk compares the property room by room against the check-in report you signed on move-in day, photographing every change. Cleaning is the most common flag, with the oven interior, washing-machine seal, limescale, grout and carpets the top five items. The report goes to landlord, agent and tenant, and is the main evidence in any deposit dispute.
Who is the inventory clerk working for?
The clerk is independent. They are hired by the landlord or agent but work as a neutral third party and are expected to produce an impartial report. In London most are members of the Association of Independent Inventory Clerks (AIIC), which has a code of practice and requires members to hold professional indemnity and public liability insurance.
Is cleaning really the biggest cause of deposit deductions?
Yes. Cleaning featured in 54% of the deposit disputes the Tenancy Deposit Scheme adjudicated in the year to March 2025, ahead of damage at 49% and redecoration at 31%. It is the single most common reason tenants lose money at check-out, and it is also the most avoidable.
Do I need to be present at the check-out?
No, and most clerks prefer you are not, because it is easier to work through the checklist without interruption. You can usually arrange a key handover and leave them to it. If you do stay, give them space and do not try to talk them through the property or pre-empt their findings.
Can the clerk force me to pay for professional cleaning?
No. The Tenant Fees Act 2019 bans landlords from requiring tenants to pay for professional cleaning as a contract term, and the Renters’ Rights Act 2025 does not change that. You can clean it yourself if it reaches a professional standard. The clerk can recommend a clean, but any deduction you disagree with can be challenged through your deposit scheme.
What if the clerk’s report is wrong or unfair?
Challenge it through the free Alternative Dispute Resolution service run by your deposit scheme (TDS, the DPS or mydeposits). Submit the signed check-in inventory, your dated check-out photos, the cleaning invoice and any correspondence with the landlord. Adjudication favours whoever brings better evidence, so strong documents matter far more than how strongly you feel about it.
How long does a London check-out take, and when do I get my deposit back?
A check-out takes 60 to 90 minutes for a 2-bed flat, longer for a furnished house, and the report is usually turned around within 24 to 72 hours. Once both sides agree on any deductions, the landlord has 10 days to return the money. If it goes to dispute, the ADR decision typically takes two to four weeks and is binding.
Does the Renters’ Rights Act 2025 change how check-outs work?
No. The Act reshapes evictions, tenancy types, rent rules and pet rights, but it leaves the deposit-protection system and the inventory process alone. The check-in benchmark, the Tenant Fees Act rules on cleaning, and the TDS, DPS and mydeposits dispute process all continue unchanged. The practical effect is more frequent move-outs once tenants can give two months’ notice at any time, so clerks will simply be busier.
