Deposit disputes are rare, but when they happen they matter a great deal to the people involved. Across England and Wales, formal adjudication is needed in only a small slice of tenancies each year. In the twelve months to March 2025,
Despite the rising value of deposits, disputes remain reassuringly rare. In the 12 months to March 2025, just 1% of all deposits (46,950 cases) required formal adjudication, meaning 99% of tenancies ended without the need for a dispute. That still adds up to a significant number of cases nationally, and for the landlord or tenant involved, the outcome can mean the difference between getting money back and losing it. This guide sets out, in practical terms, what independent adjudicators are actually looking for when they decide who keeps what.
How adjudication actually works
Every deposit taken on an assured shorthold tenancy in England and Wales must be protected in one of three government-approved schemes: the Deposit Protection Service (DPS), the Tenancy Deposit Scheme (TDS), or mydeposits. Every landlord in England and Wales must protect your deposit in one of three government-approved schemes within 30 days of receiving it: mydeposits, the DPS, or the TDS. If landlord and tenant cannot agree on deductions at the end of the tenancy, either party can escalate the disagreement to Alternative Dispute Resolution, or ADR. If agreement cannot be reached, either party can escalate to Alternative Dispute Resolution. An independent adjudicator reviews the evidence and issues a binding decision. ADR is free at all three schemes. You do not need a solicitor.
The process itself is largely paperwork, not a hearing. Like all schemes, ADR is evidence-driven and paper-based, adjudicators don't split the difference for fairness, they decide on evidence. There is normally a short window, typically fourteen calendar days, for both sides to submit their evidence once a case is referred. You then have 14 calendar days from the date of that email to submit your evidence. Once that window closes, an adjudicator reviews the file and issues a decision, usually within around 28 days. Once both parties have submitted their evidence, adjudicators typically return a decision within 28 days, and the decision is binding on the scheme, which releases the deposit in line with it. That decision is final within the scheme itself. The decision made by an adjudicator through the resolution service is final and legally binding, and there is no appeal process through the deposit scheme. Decisions can only be challenged in a court of law in very specific and rare circumstances.
The principle that decides most cases: who has to prove what
This is the single most important thing for both landlords and tenants to understand. The deposit remains the tenant's money until the landlord proves otherwise. Many landlords don't realise that the onus is on them to prove they have a legitimate claim to a share of the deposit, whilst the tenant has no obligation to prove their position. This is because the deposit remains the tenant's money until the landlord has successfully proven their claim. That means a landlord who turns up with a vague, unsigned inventory and no photographs is likely to lose the argument by default, however reasonable their underlying complaint might be.
What adjudicators actually want to see
Adjudicators are not swayed by tone, history between the parties, or how the tenancy felt to live through. It doesn't matter if the landlord didn't carry out the work. It doesn't matter if the landlord or agent were terrible during your tenancy. Emotional appeals don't work. What they want is a clear, dated paper trail that lets them compare the start and end of the tenancy. The core documents are:
Check-in and check-out reports. These are described repeatedly as the backbone of any claim. Check-in and check-out reports are the backbone of any dispute. A dated, signed check-in report showing the property's condition when you moved in is the clearest way to prove that damage existed before your tenancy. A report produced by an independent inventory clerk carries more weight than one written by the landlord alone. Tell the scheme if you were not there at the inspection, or your landlord did the check out inspection themselves, because the scheme might consider that a check done by your landlord is not as reliable as one done by someone else.
Dated, labelled photographs and video. Photos need context to be useful. Before and after photos allow adjudicators to see the reason for the claim. Photos should be submitted with an explanation of what they're showing, such as colours, item description, and marks on surfaces, and clearly show the alleged damage or defect.
Invoices, receipts and quotes. A paid invoice carries more weight than an estimate. Invoices for completed work carry more weight than estimates, and estimates carry less weight than paid receipts. Contractors should itemise the work. These documents illustrate claim costs for repairs or restoration, redecoration, replacement of damaged goods, gardening, cleaning and waste disposal, and where possible the contractor should itemise their costs, detailing the work completed.
The tenancy agreement itself. Adjudicators check what the contract actually says a tenant is responsible for before considering a deduction reasonable. If the clauses are unclear, the claim can fail on that basis alone.
Rent statements for arrears claims. A rent account statement is important when the claim involves rent arrears. It helps the adjudicator understand what payments were owed, what payments were made and what payments were missed, documenting the property, the person the account relates to, and a breakdown of how arrears are calculated.
Presentation matters too. Adjudicators work through large volumes of cases and will not hunt for your point buried in an email chain. The adjudicator is human. They will not look through an email chain or an entire tenancy agreement or inventory to find what you are talking about. Submit evidence in a logical order, room by room, with each item clearly cross-referenced between the check-in and check-out reports.
Fair wear and tear, and the trap of betterment
Two legal concepts decide most contested claims. Fair wear and tear is the gradual, unavoidable deterioration that comes from ordinary living, and landlords cannot charge for it. The House of Lords defines fair wear and tear as reasonable use of the premises by the tenant and the ordinary operation of natural forces. A high-traffic carpet fading is wear and tear; a wine stain or burn is damage. A carpet becoming slightly worn in a high-traffic area like a hallway is fair wear and tear, while a red wine stain or a burn mark on the same carpet is considered damage.
Betterment is the second trap, and it catches out landlords more than tenants. A claim cannot leave the landlord better off than they would have been anyway. The landlord should not end up, either financially or materially, in a better position than they were at the start of the tenancy, or than they would have otherwise been after allowing for fair wear and tear. If a carpet was brand new at the start of a two-year tenancy, it would be a two-year-old carpet at the end, and claiming the full cost of a new replacement would lead to betterment. In practice this means working from an item's depreciated value, not its replacement price, and showing your workings. A useful illustration: if a mattress cost £400 new, has an expected life of eight years, and is four years old at the end of the tenancy, half its life is gone, so its remaining value is around £200. Long tenancies make redecoration claims particularly hard to justify. This is particularly important in disputes where the tenant has lived in the property for a long time. The adjudicator is unlikely to make an award for redecoration costs where the tenant has lived in the property for five or more years, as the landlord would probably have needed to redecorate anyway.
Where disputes actually come from
The same categories dominate year after year. Cleaning remains the most frequent trigger for disagreements, featuring in 54% of cases. Damage followed closely at 49%, with redecoration the cause in 31%, while gardening accounted for 14% of disputes and rent arrears appeared in 10%. Cleaning disputes are usually about mismatched expectations rather than genuine disagreement over facts. Cleaning continues to be the single biggest source of disputes, often coming down to differing expectations at check-out, which could be avoided with clearer inventories, better communication, and photographic evidence.
A practical checklist for landlords
Build the evidence pack from day one, not at the point of dispute. Protect the deposit correctly and issue the prescribed information promptly. Provide tenants with the prescribed information and check they understand how deposit protection works. Carry out thorough, dated inventories at check-in and check-out. Keep all maintenance and communication records. Use an independent clerk for the check-out where possible rather than doing it yourself, since the whole value of an independent report is its objectivity. Keep every invoice and quote, itemised rather than lump-sum. Before submitting a claim, check it against the betterment principle: are you asking for more than your actual financial loss? Adjudicators have been known to dismiss an entire claim where the supporting report was too vague to help, so precision protects you far more than a generous list of deductions.
A practical checklist for tenants
Get your own copy of the check-in report at the start of the tenancy and compare it carefully against the check-out report when the dispute arises. Find your inventory and report from your check-out inspection. Compare it from when you moved in with the check out report and make notes of any changes. Attend the check-out inspection in person if at all possible, and query anything that looks wrong on the spot. Be there at the check-out inspection if you can, and go round with the agent to make sure they note things down properly. If a claim is not clearly supported by the paperwork, say so directly: if there is a claim for a deposit deduction that is not clear from the inventory and check-out report, you can point this out to the adjudicator and this attempted deduction will likely be dismissed. Getting a couple of independent quotes for cleaning or gardening work can also help challenge an inflated deduction.
Final word
Adjudication rewards preparation, not persuasion. The schemes exist precisely so that ordinary disagreements over cleaning, damage or a few days of unpaid rent can be settled quickly and fairly, without either side needing a solicitor or a day in court. An independent adjudicator reviews the evidence from both sides and makes a binding decision, usually within 28 to 30 working days of receiving all the documents. Whether you are a landlord protecting a legitimate claim or a tenant challenging an unfair one, the same rule applies: get the paperwork right at the start of the tenancy, keep it organised throughout, and let the evidence, not the argument, do the work.
