What Happens if Your Deposit Goes to Adjudication?

A deposit dispute rarely starts out looking like one. It starts as a line on a check-out report — "property requires professional clean" — and an email you were not expecting. If you and your landlord cannot agree a figure between yourselves, the scheme holding your deposit decides it instead, through a process called adjudication. Our guide to getting your deposit back covers the prevention side. This one covers what happens when prevention has not worked: the deadlines, who has to prove what, which evidence an adjudicator can actually act on, and why cleaning claims are simultaneously the most common dispute and the most winnable.

How many deposits actually get this far

Fewer than you would think from the way the internet talks about it. There are around 4.7 million deposits protected across England and Wales, with an average value of £1,175, and in the 12 months to March 2025 roughly 1% of them — 46,950 cases — went to formal adjudication. Ninety-nine tenancies in a hundred end without a dispute at all.

But of the ones that do reach an adjudicator, cleaning is the claim that turns up most often.

Cleaning leads because it is the one claim with no objective measure. Damage is binary — the worktop is chipped or it is not. Cleanliness is a judgement, both parties genuinely believe they are right, and the dispute is really an argument about what standard applied in the first place. Our guide to whether cleaning is the tenant's or the landlord's responsibility sets out where that standard comes from.

Which scheme holds your deposit sets the timetable

There are three government-approved schemes in England and Wales: the Deposit Protection Service, mydeposits and the Tenancy Deposit Scheme. Your deposit must have been placed in one of them within 30 days of the landlord receiving it (GOV.UK). Each operates a custodial version, where the scheme holds the cash, and an insured version, where the landlord holds it and the scheme protects it. Which one you are in changes the deadlines, so the first thing to do is find out.

mydeposits publishes its own timetable, and it is representative of how these processes are shaped:

The Deposit Protection Service runs to its own clock and gives tenants 14 calendar days from the date of its email to submit evidence. It is worth knowing the mechanics before you start: you can upload up to 40MB of files per upload and as many uploads as you need, but the supporting statement that explains them is capped at 1,000 characters (DPS). Write that statement properly in a text editor first, because 1,000 characters is not many and it is the only place you get to tell the adjudicator what they are looking at.

The practical point is that the clock runs whether you engage or not. Miss the evidence window and the adjudicator decides on what the other side submitted.

Who has to prove what

This is the part most tenants do not know, and it changes how the whole thing feels. The deposit is your money. It remains the tenant's property until the landlord can show otherwise, which puts the responsibility squarely on the landlord to prove a right to any part of it — the tenant has no obligation to prove their own position at all (mydeposits).

Claims against a deposit are civil claims, so the adjudicator does not need to be certain. They have to be persuaded on the balance of probabilities: they look at all the evidence and decide which version of events is more likely. A landlord has to establish three things to that standard — that you breached a term of the tenancy agreement, that they can evidence the breach, and that the breach caused them a financial loss.

None of which means you should sit back and submit nothing. An unanswered claim with a dated check-out report and photographs attached is very likely to succeed, because it is the only account the adjudicator has. The burden being on your landlord means you are rebutting, not proving — a much easier job, but still a job.

The four questions an adjudicator works through

Adjudicators assess cases in a consistent order, and knowing it tells you exactly what your evidence has to do. The questions are: what is this claim for; what were the tenant's obligations under the tenancy agreement and in general law; did the tenant fail to meet them, and where is the evidence for that; and if so, what loss did it cause the landlord, allowing for fair wear and tear, with what evidence quantifying it (NRLA).

And then the line that matters most: "Adjudicators will not seek or ask for further evidence when assessing a case. It's down to the landlords and tenants to support their claim." There is no hearing, no phone call, no request for clarification and no second round. Whatever is in the file on the deadline is the whole case.

The two limits that decide most cleaning claims

Fair wear and tear

Fair wear and tear is "reasonable use of the premises by the tenant and the ordinary operation of natural forces" — the depreciation a property undergoes through ordinary day-to-day use across the length of the tenancy (Deposit Protection Service). It is not chargeable to the deposit, and adjudicators weigh it against the length of the tenancy, the number and age of the occupants, and the quality and remaining lifespan of whatever is being claimed for. A family of five after four years is not held to the standard of a single tenant after eight months.

Betterment

The landlord cannot end up better off, financially or materially, than they were at the start of the tenancy or would have been at the end of it after fair wear and tear. Claiming beyond that point is betterment, and an adjudicator cannot award it. The DPS puts the principle plainly: "The claim shouldn't be used as an opportunity to make upgrades at the tenant's cost."

Applied to cleaning, betterment is the single most common reason a cleaning claim fails or gets reduced. Expecting the property back cleaner than it was handed over is betterment. Claiming the full cost of a professional end of tenancy clean when there were already cleaning defects at check-in is betterment. If the oven had baked-on grease in it when you moved in and the check-in report records that, the landlord is not entitled to a professionally degreased oven at your expense — our guide to what is included in end of tenancy cleaning sets out the scope that normally applies instead.

Which is why the check-in report, not the landlord's preference and not the word "spotless", is the benchmark the whole dispute is measured against.

What evidence actually counts

Adjudicators cannot act on hearsay, opinion or assertion. What they can act on, and what the schemes say makes evidence strong, is specific:

• The inventory — a detailed written record of the property's condition and contents at the start. It carries most weight when both parties signed it, or when there is evidence the tenant was sent it and given between seven and ten days to comment.
• Check-in and check-out reports. These are the documents that let an adjudicator compare the condition of the property at the start and the end directly. Timing matters: the check-out should happen as near as possible to the property being left empty and the keys returned.
• Photographs, properly taken. If you photograph separately from the formal reports, make sure the camera adds a visible date and time stamp. Take a wide shot of the whole wall or room for context, then a close-up of the specific issue — a close-up on its own proves nothing about where it is or how big it is. Shoot in natural daylight: "Blurry, dark, or out of focus images will not help your case" (mydeposits).
• Invoices and quotes. A landlord must show the cost is reasonable and proportionate to the deterioration the tenant actually caused, with a clear breakdown of the work including materials and labour. Usefully for both sides, an estimate for work not yet done and an invoice for work completed are considered equally by an adjudicator.
• Written communications. Texts, WhatsApp messages and emails are all valid evidence of what was agreed and discussed during the tenancy. The conversation where the agent said the oven was fine is evidence, if you kept it.

There is a corollary that cuts the landlord's way too. A check-out report produced by the landlord or their own agent is not independent, and on its own it carries limited weight — it needs date-stamped photographs showing the actual cleaning defects to stand up. A claim that amounts to "the property needed cleaning, here is an invoice" is a weak claim, however confidently it is written.

And the other corollary, which is the practical reason to use a professional at all: a dated invoice that itemises the rooms and tasks completed, paired with your own timestamped photographs taken after the clean and before you handed the keys over, is direct documentary evidence of the condition you left the property in. That is a materially stronger position than a tenant who cleaned it themselves and took no photographs.

What the decision is — and what it is not

The adjudicator reviews the file and decides how the deposit is split. The decision is final and binding on both parties, there is no appeal through the scheme, and challenges in court are rarely successful. GOV.UK is equally blunt: you do not have to use the service, but if you do, both you and the landlord have to agree to it, and "you'll both be asked to provide evidence, and the decision made about your deposit will be final" (GOV.UK).

Once the decision is made the scheme releases the money accordingly. If you settle without adjudication instead — which is what happens in the overwhelming majority of cases — your landlord must return your deposit within 10 days of you both agreeing how much you get back.

Two honest limits. Adjudication apportions a deposit on the evidence; it is not a compensation process and it does not punish anyone for being difficult. And it is a documents exercise — the adjudicator never sees the property, so a clean you cannot evidence is, for this purpose, a clean that did not happen.

What to do before you hand the keys back

Everything above argues for the same handful of actions, all of which happen before there is any dispute to have.

1. Dig out the check-in report and inventory before you clean, not after. That document defines the standard you are being measured against, and it is the only thing that tells you which of the landlord's expectations are actually enforceable.
2. Clean once the property is empty. A clean done around furniture and boxes cannot reach the places a check-out report looks at, which is also why an end of tenancy clean is scoped the way it is.
3. Photograph every room after the clean and before the keys go back. Wide shot then close-up, timestamp on, natural daylight. Include the oven interior, the shower screen, inside the fridge and the kitchen floor — the items most often raised.
4. Keep the invoice, and make sure it itemises the scope rather than just saying "cleaning". A breakdown is what makes it evidence rather than a receipt.
5. Ask for the check-out inspection to be carried out as close as possible to the point the property is empty and the keys are returned, and attend it if you can.
6. If a deduction is proposed, ask for it in writing and itemised, compare it line by line against the check-in report, and reply with your photographs and invoice. Most deductions are settled at this stage — the deposit guide sets out that exchange in detail.

This guide covers England and Wales. Scotland and Northern Ireland operate separate deposit schemes with their own rules and timescales.

Moving out in Berkshire or Surrey

Berkshire EcoClean cleans to the room-by-room inventory specification that check-out reports are written against, with a supervisor verifying the property against the checklist before we leave, and a 72-hour re-clean guarantee if the agent or landlord raises a cleaning point after check-out. You get a dated invoice setting out what was actually done — which, as above, is the part that carries weight if the clean is ever questioned. Our end of tenancy cleaning checklist is the same specification, published, if you would rather do it yourself.

What no cleaner can honestly promise is the deposit decision itself, because that also turns on wear, damage and the inventory beyond cleaning. What we can do is make the cleaning half of it evidenced and defensible. We work across Ascot, Windsor, Bracknell, Maidenhead, Reading, Slough and Egham, plus Newbury and Wokingham — see every area we cover. For what it costs, our Berkshire end of tenancy cost guide has the figures by property size. Request a fixed quote or book online.
