A deposit dispute is not an argument. Nobody visits the property. Nobody hears you out. An adjudicator reads two files and decides which one supports its claims.
That single fact should change what you send. Most tenants submit a defence — a long explanation of why the landlord is being unfair. Adjudicators do not weigh sincerity. They weigh whether a specific deduction has been evidenced, and the burden of proving it sits with the landlord.
Here is how the process actually runs and what belongs in your file.
The landlord has to prove the deduction
This is the most useful thing to understand, and it surprises people.
You do not have to prove the property was fine. The landlord has to prove that a specific thing was damaged beyond fair wear and tear, that it was your responsibility, and that the amount claimed is reasonable. If they cannot evidence all three, the adjudicator returns that portion to you.
That is why a vague claim — "cleaning: £250", "damage to walls: £180" — often fails on its own. No invoice, no before-and-after, no itemisation, no award.
Your job is narrower than you think: make it impossible for the landlord's evidence to stand unchallenged where it is weak, and account for the places where it is strong.
How the timeline works
The exact days vary a little between schemes, but the shape is consistent:
- At the end of the tenancy, the landlord proposes deductions
- If you do not agree, there is a negotiation window — typically around 14 days — where you can settle it between you
- If you cannot, either side raises a formal dispute. The schemes generally expect this within 90 days of the tenancy ending
- The other party has to respond, usually within 14 days
- Both sides submit evidence, often with a final short window of a few working days to add anything last
- An adjudicator reviews the file, typically within about 28 days
From formal dispute to decision is commonly around two months. The undisputed part of your deposit should be released to you while the rest is held.
Two things follow from that timeline. First, missing a deadline can cost you the whole dispute regardless of the merits — diarise every date the scheme gives you. Second, you cannot gather evidence after the fact. The photographs that matter most in a dispute were taken the day you moved in, by someone who had no idea they would ever be needed.
What actually persuades an adjudicator
Dated before-and-after pairs of the same thing. A photograph of a stained carpet proves a stain exists. A photograph of the same carpet, from the same position, on the day you moved in, is what turns that into a question about when it happened. Pairs beat singles every time.
Context in the frame. A tight close-up of a scratch could be anywhere in any property. Take the wide shot too, showing the surface in relation to a door, a window, a radiator — something fixed and identifiable. Then the close-up.
The signed inventory, and your comments on it. If the check-in inventory recorded the carpet as "worn, light staining near window" and you kept it, that sentence does more work than twenty photographs.
Meter readings with the meter and the serial number visible. Utilities deductions collapse quickly when you have this and the landlord does not.
The messages you sent at the time. A dated email reporting a leak in March is powerful in a dispute about damp in September. It shows the landlord knew, and it puts the failure to act on their side of the ledger.
Specific, factual descriptions. "Scratch approximately 15cm on the left of the living room wall, next to the window, present on the day of move-in" is evidence. "The flat was in a bit of a state" is not.
Put the file in order
An adjudicator reads your file without you there to explain it, so the order matters almost as much as the contents. Build one dated timeline rather than a pile of attachments:
- Move-in: the check-in inventory, your comments on it, and your day-one photographs
- During the tenancy: each problem you reported, when you reported it, and what came back
- Repairs and visits: the dates, and photographs once the work was done
- Move-out: your last-day photographs, the final meter readings and when you returned the keys
- After the tenancy: the proposed deductions, your replies, and every deadline the scheme gave you
Keep each event as its own dated entry. If something changes, add a new dated note rather than overwriting the earlier file, so the history stays readable.
Put a one-page index at the front: what is in the file, in what order, and which deduction each item answers. Include invoices or quotes only if you actually received them, labelled with the charge they relate to.
If your own move-in record is thin, say so rather than filling the gap. Do not recreate photographs and present them as older than they are. Use what you do have, such as the check-in inventory, the tenancy agreement and your messages from the first weeks, and keep dated records from then on.
Send copies, and only what the dispute needs
- Submit evidence through the route the scheme gives you, not as a stream of loose emails or chat messages
- Send only what relates to the deductions in dispute
- Leave out passwords, full copies of ID documents and other people's personal information unless the scheme specifically asks for them
- Keep your own complete master copy, and note what you sent and when
What does not help
- Long letters about how unreasonable the landlord has been
- Arguments about their character, or about unrelated disputes during the tenancy
- Screenshots of angry text exchanges
- Photographs with no date and no context
- Claims you cannot support, mixed in with claims you can — one unsupported assertion makes an adjudicator read the rest more sceptically
- Edited, filtered or cropped images where the original still exists
That last one matters more than people expect. Send originals. A cropped image raises a question about what was cropped out, and you will not be there to answer it.
Concede what you should concede
If you burned the worktop, say so, and dispute the amount rather than the fact.
This is not resignation, it is strategy. A file that disputes everything, including the obvious, reads as a file that disputes everything reflexively. A file that says "we accept the worktop, we dispute the £400 figure for it and here are three quotes at half that, and we dispute the cleaning charge entirely because here is the property on the day we left" reads as a file that has been honest about the facts. Adjudicators are human, and they have seen a great many of both.
Partial concession also narrows the dispute to the points you still disagree about.
Betterment, and why it matters
A landlord cannot use your deposit to end up better off than they started.
If a six-year-old carpet is damaged, you are not liable for a brand-new carpet. The adjudicator will consider the age and expected lifespan of the item and apportion accordingly. The same applies to paintwork, appliances and furnishings.
So when you see a deduction that amounts to a full replacement of something that was already well used, name it. Ask what the item's condition and age were at the start of the tenancy — and if the check-in inventory says "carpet: fair, some wear", quote it.
Build the file before you need it
Nearly everything above depends on something you did months or years earlier. That is the uncomfortable part of deposit disputes: the work that decides them is done at move-in, by someone with no dispute in sight.
A practical minimum, on the day you get the keys and before the boxes come in:
- One wide photograph of every room, from the doorway
- Close-ups of every mark, with a wider shot connecting each to a fixed feature
- Meter readings, with the serial numbers legible
- Your own written comments on the inventory, sent back to the landlord or agent in writing
- Everything kept somewhere you will still be able to find in two years
Our move-in inspection checklist goes through this room by room, and the rental damage photo checklist covers how to shoot the individual marks.
The easiest way to build that file is at the two ends of the tenancy: our move-in checklist for day one and our move-out checklist for the last day.
Put it in writing
If you disagree with a deduction, or the deposit has not come back, reply in writing, one charge at a time. Our free deposit letter can help: choose England and Wales, list each charge you dispute and why, and it writes a polite, dated letter asking for the money or for the check-in inventory and receipts, and saying you will use your scheme's free dispute service if you cannot agree. Nothing you type leaves your browser.
Where RentSeal fits
RentSeal keeps that record in one place for one tenancy — photos, notes and documents, organised by room and dated as they are added, so that two years later it is a file you can hand over rather than a camera roll you have to search. You can read how it works first.
It does not decide who is responsible for anything, and it does not guarantee any outcome. What it does is make the history easy to review — which, when the decision is made by someone reading a file, is most of the job.
This guide explains the process in general terms and is not legal advice. For your own situation, speak to Citizens Advice, Shelter or a housing solicitor. It is worth doing that early if you receive court papers or a formal legal letter, if you are unsure which deadline applies to you, or if you are asked to sign something giving up part of the deposit that you do not fully understand.
