Evidence for tenancy deposit disputes: what adjudicators look for

England, Wales, Scotland & NI Last reviewed: 8 min read

When a landlord and tenant can’t agree how much of a deposit should come back, an independent adjudicator decides on the evidence. This is what that evidence needs to show, with links to each scheme’s own guidance.

How a deposit dispute is decided

In most private tenancies across the UK, a deposit has to be protected in a government-approved scheme, and every scheme offers a free way to resolve a disagreement about how much should be returned, without going to court.

An independent adjudicator reads the evidence each side submits and decides how the disputed amount should be split. The Deposit Protection Service describes this as a decision on the balance of probabilities. The adjudicator can only go on what is in front of them, which is why the quality of your records matters more than the strength of your feelings about the property.

Who has to prove what

The starting point surprises some landlords: the deposit is the tenant’s money. The schemes’ guidance is consistent that it is for the landlord or agent to show they are entitled to keep part of it, and the tenant doesn’t have to prove the property was fine. The Government’s statutory guidance on the Tenant Fees Act says the same for England: a landlord or agent needs evidence to support any deduction.

In practice, that means a gap in the evidence usually counts against the person claiming. If you can’t show what an item was like at the start, or what it cost to put right, a deduction for it is hard to justify, however obvious it seemed at the check-out.

The evidence adjudicators look for

The schemes’ own guidance points to the same core set of documents:

mydeposits sums up how it weighs all this in four words: consistency, credibility, completeness and relevance. Evidence that contradicts itself, can’t be dated, leaves gaps or has nothing to do with the claimed item carries less weight.

Check-in against check-out

Almost every damage or cleaning claim comes down to a comparison: this is how the item was at the start, this is how it was at the end, and the difference is more than fair wear and tear. Both halves of that comparison need to be solid.

Our check-in inventory checklist covers how to build the first half of that comparison properly.

Why dates and detail matter

A photo proves little if nobody can tell when it was taken. The Deposit Protection Service asks for photos that are clear, in colour and date-stamped, and mydeposits warns that dark, blurry or undated images make poor evidence. For reports made only of photos or video, it suggests making the time of the inspection especially clear.

Bear in mind that the date an ordinary phone photo shows comes from metadata that can be edited, and the other side in a dispute may say so. Evidence is more credible when its timing is corroborated: photos embedded in a report the tenant acknowledged at the time, an email that sent them to the tenant on the day, or an independent timestamp that shows a file existed at a particular moment and hasn’t changed since. None of these guarantees an outcome, and how any evidence is weighed is up to the adjudicator, but each removes a point of argument.

Detail matters as much as dates. “Carpet stained” invites the question of how big, where and whether it was there before. “Red wine stain, about 10 cm, in front of the sofa; not recorded at check-in (see check-in photo 14)” answers it.

Fair wear and tear

A tenant isn’t responsible for the normal deterioration that comes from living in a home. The schemes draw on a long-standing legal description of fair wear and tear: “reasonable use of the premises by the tenant and the ordinary operation of natural forces”.

Adjudicators look at the circumstances of the tenancy, including:

As a rough guide, gradual changes such as light scuffs, flattened carpet in walkways, sun-faded curtains or minor marks where furniture stood tend to be treated as wear and tear, while burns, large stains, holes, breakages and missing items point to damage. The line depends on the facts, which is why the check-in detail matters. Fair wear and tear applies to condition, not cleanliness: a property handed back dirty isn’t excused by the length of the tenancy.

Proportionate charges: betterment and apportionment

Even where there is damage beyond fair wear and tear, the charge has to be fair. Two principles do most of the work.

No betterment

A deposit isn’t an insurance policy that pays new for old. A landlord shouldn’t end up in a better position than if the tenancy hadn’t caused the damage, so the full cost of a brand-new replacement for an old item is rarely awarded.

Apportion by age and expected life

The Deposit Protection Service gives a worked example. A carpet has an expected life of five years and is damaged beyond repair after two. Replacing it costs £500. The tenant has cost the landlord the remaining three years of the carpet’s life, 60%, so a reasonable contribution is about £300.

A scheme adjudicator can’t award more than the deposit held. A larger claim has to go to court.

Cleaning: the most common claim

In figures published in June 2026, the Deposit Protection Service reported cleaning as the most common reason for deposit claims in 2025, for the fifth year running, making up roughly three in ten claims, ahead of damage, rent arrears and redecoration.

The standard is the condition at the start. The schemes’ guidance is that a tenant has to return the property as clean as it was at check-in, not to a higher standard, and that a clause requiring a professional clean regardless of the starting condition is unlikely to be enforced. To support a cleaning claim, you need cleanliness recorded at check-in (separately from condition), dated check-out photos of the same places, and an itemised invoice.

Deadlines and process by nation

Deposit disputes at a glance, as reviewed in September 2026. Scheme rules change, so check your scheme’s current terms.
Nation Raising a dispute Getting the money back
England and Wales Free, and both sides must agree to use it. Each scheme sets its own time limit, and some are around three months from the end of the tenancy, so contact the scheme promptly. The deposit should be returned within 10 days of landlord and tenant agreeing the amount.
Scotland The landlord applies to the scheme for repayment at the end of the tenancy. The tenant then has 30 working days to respond or dispute it. If the tenant doesn’t respond within 30 working days, the landlord is repaid within 5 working days.
Northern Ireland Free. A tenant’s request for referral goes ahead even without the landlord’s agreement; a landlord’s request needs the tenant’s. nidirect says a decision should come within 20 working days, with the deposit repaid within 5 working days of the final decision.

In England, the Renters’ Rights Act 2025 moved most tenancies onto assured periodic tenancies from 1 May 2026. Deposit protection still applies, and we found no change to how the schemes resolve disputes.
