Cleaning is the most common reason UK deposits get reduced, and it is not close. Deposit Protection Service data reported in June 2026 shows cleaning accounted for 29.38% of all deposit claims over the year, the largest single category, and the top cause for five consecutive years. The share has risen steadily from 24.57% in 2021.
Cleaning also turns up in a majority of the disputes that reach adjudication, usually alongside other claims rather than on its own. The reason is not that tenants are lazy. It is that cleaning is the one deduction category where the standard is genuinely ambiguous, and ambiguity produces arguments.
This article covers why that happens, how adjudicators actually decide these cases, what evidence wins them, and what both tenants and landlords should do differently.
Why cleaning specifically
Damage is easy to adjudicate. A cracked worktop is cracked or it is not. A missing door is missing. Cleanliness is a spectrum, and two reasonable people can look at the same oven and disagree about whether it is clean.
Three things make it worse.
The standard is relative, not absolute. You are not required to hand back a showroom. You are required to hand back the property as clean as it was at check-in, allowing for fair wear and tear. That means the check-in inventory is the yardstick, and if the check-in inventory is vague, so is the yardstick. "Kitchen: clean" tells an adjudicator almost nothing.
Cleaning degrades invisibly. Limescale, oven carbon and grout discolouration build so gradually that a tenant genuinely does not perceive the change over two years. They are not being dishonest when they say the flat looks the same as when they moved in. To them it does. The clerk, seeing it fresh against a photograph, sees something different.
It is cheap to claim and hard to disprove. A cleaning deduction is often a few hundred pounds. Many tenants conclude that disputing it is not worth the effort, which means weak claims sometimes succeed and the practice continues.
The scale of it
A few numbers worth holding in mind.
| Figure | What it means |
|---|---|
| 29.38% of claims | Cleaning, the largest single category |
| 24.57% in 2021 | The same figure five years earlier |
| 5 years running | Cleaning has been top every year |
| Around 1% of deposits | Reach formal adjudication at all |
That last figure is the one most people miss. The overwhelming majority of tenancies end without a dispute, and the overwhelming majority of disagreements are settled directly between the parties. That matters strategically: the evidence you hold is most valuable during the negotiation, not at adjudication, because the negotiation is where nearly everything is actually resolved.
How adjudicators decide
When a cleaning claim reaches formal adjudication, the deciding factor is almost always evidence quality rather than the cleaning itself. The scheme is deciding on documents, without visiting the property, often months after the tenancy ended.
They are looking for:
The check-in inventory, ideally with dated photographs. Without it, a landlord struggles to prove the property was ever cleaner than it was left. The burden of proof sits with the landlord, who is the one claiming against money that legally belongs to the tenant until proven otherwise.
The check-out report, covering the same items in the same order, so the two can be compared directly.
Photographs of the specific items claimed for, not general shots of a room. A wide photograph of a kitchen proves very little. A close, dated photograph of an oven interior proves a great deal.
An invoice for remedial cleaning that is itemised and proportionate to the work described.
A claim for "£350 cleaning" with no breakdown and no check-in photographs tends to fail or be heavily reduced. A claim for "£85 oven deep clean" with a check-in photograph, a check-out photograph and a matching invoice tends to succeed in full.
Proportionality matters too. Adjudicators reduce claims that look punitive. A £400 cleaning claim on a one bedroom flat sits well outside the market rate of roughly £150 to £250 and invites scrutiny of the whole submission.
Fair wear and tear, and how it is applied
This is where a large share of cleaning claims are reduced. Adjudicators separate deterioration from normal use over the tenancy length from actual cleaning failures.
| Situation | Usually wear and tear | Usually cleaning |
|---|---|---|
| Carpet flattened along a hallway after 3 years | Yes | |
| Carpet with visible stains | Yes | |
| Grout greyed over several years | Yes | |
| Grout with soap scum or mould | Yes | |
| Oven with light discolouration | Yes | |
| Oven with baked-on carbon | Yes | |
| Scuffs at handle height on a wall | Yes | |
| Crayon or ingrained marks on a wall | Yes | |
| Limescale after 4 years in a hard water area | Arguable | Arguable |
| Mould in a shower sealant | Yes |
Length of tenancy changes the calculation substantially. A four year tenancy attracts far more wear and tear allowance than a six month one, and a landlord claiming full replacement cost for a carpet at the end of its expected life will normally see that reduced to reflect the remaining life it actually had.
A landlord who claims wear as cleaning damages their own case, because it makes the entire submission look opportunistic and invites the adjudicator to scrutinise the rest.
If you are a tenant
Get the check-in inventory on day one and read it properly. If it says the oven is clean and the oven is not, say so in writing within the window your agreement allows, usually seven or fourteen days. That single email protects you two years later. Attach photographs.
Photograph the property when you move in. Not a walkthrough video, individual dated photographs of specific things: the oven interior, the shower screen and grout, the carpets including any existing marks, inside the cupboards, the window tracks, the washing machine seal. Store them where you will still have them at the end of the tenancy, meaning cloud storage or emailed to yourself, not just on a phone you will replace.
Clean the property empty, after the furniture has gone.
Photograph everything again when you leave, matching the check-in shots as closely as you can. Same angles, same items.
Keep an itemised checklist if you paid a company. A receipt saying "cleaning £250" proves you spent money. An itemised checklist proves what was covered, which is the thing in dispute.
If a deduction is proposed, ask for the breakdown and the evidence before agreeing to anything. You are entitled to see what you are being charged for. A polite, unemotional request for an itemised list and the supporting photographs resolves a surprising number of claims on its own, because many are round numbers that do not survive contact with detail.
Watch the clock. Deposit schemes have time limits for raising disputes, commonly three months from the end of the tenancy.
Ask for the undisputed portion to be released while the rest is decided. You should not be out of pocket on the parts nobody disagrees about.
If you are a landlord or agent
The same evidence discipline protects you, and it is why well-run portfolios rarely end up in adjudication.
Invest in a proper check-in inventory with photographs and specific wording. "Kitchen: clean" is worth very little. "Oven interior clean, no carbon deposits on base or door glass, photographed" is defensible two years later.
Photograph the contested categories in advance. From how these cases run, the recurring items are: oven interior, shower screen and grout, carpet condition in traffic areas, wall marks, window tracks, appliance seals and extractor filters. Photograph those specifically at check-in, every time.
Give the tenant a copy with a written window to dispute it. A tenant who has accepted the inventory has accepted the baseline, and that materially strengthens your position.
Claim for the remedy, not for the inconvenience. An itemised invoice for the specific work needed is far more likely to be awarded in full than a round number.
Account for fair wear and tear honestly. It costs you the weak parts of a claim and protects the strong parts.
Turn the property around properly between tenancies, so the next check-in genuinely reflects a clean baseline. A property that was not clean at check-in cannot support a cleaning claim at check-out.
The economics, from both sides
For a tenant: a typical deposit is five weeks' rent. On a £1,400 a month tenancy that is roughly £1,615. An end of tenancy clean costs £180 to £420. Spending around 15% of the deposit to remove the single most common reason for losing part of it is a reasonable trade, particularly when a reputable company includes a re-clean guarantee if the agent flags something.
For a landlord: the calculation is about void periods and repeat disputes. A property that fails its own check-in standard is harder to let, and it invites the same argument at the other end of the next tenancy.
What would actually fix this
The pattern in the DPS numbers suggests the problem is documentation, not dirt. The share of claims involving cleaning has risen every year for five years, which is unlikely to reflect tenants suddenly becoming less clean. It more plausibly reflects a rental market with higher deposits at stake, more professionalised inventory reporting, and more claims being made.
Tenancies that begin with a detailed, photographed inventory and end with a matching check-out report produce far fewer arguments, because there is much less to argue about. Both sides know the standard, and both sides can see whether it was met.
If you are starting a tenancy this month, the most valuable thirty minutes you will spend is photographing the property before you unpack.
Frequently asked questions
Who has the burden of proof? The landlord. The deposit belongs to the tenant until the landlord demonstrates a valid claim against it.
Is adjudication free? Free to tenants through the scheme holding the deposit. It is decided on documents rather than a hearing.
Can I refuse to agree a deduction? Yes. If you do not agree, the disputed amount is held by the scheme while it is decided, and the undisputed portion should be released to you.
What if there was no check-in inventory at all? That significantly weakens a landlord's claim, because they have no baseline to prove the property was cleaner at the start.
Does a professional cleaning receipt guarantee I keep my deposit? No, but it helps considerably, especially an itemised one. What is being judged is the state of the property, not the money you spent.
How long does the landlord have to propose deductions? Deposit schemes require the deposit to be returned within ten days of both parties agreeing the amount. If there is no agreement, the dispute process begins.
