Deposit dispute adjudication: how the decision is made

Why it matters

Landlords lose adjudications far more often than they expect, and the reason is almost always evidence rather than merit. The adjudicator starts from the position that the deposit belongs to the tenant and the landlord must prove any deduction.

Legal requirements

• The burden of proof sits with the landlord for every deduction claimed.
• The adjudicator applies the tenancy agreement, the inventory and the law on wear and tear.
• Undisputed amounts must be released without waiting for the dispute to conclude.
• Adjudication decisions under the schemes are binding once both parties opt in.

Common mistakes

• Claiming for a full replacement when the item was already part way through its life.
• Submitting photographs with no date, no room reference and no check in comparison.
• Relying on an inventory the tenant never signed or acknowledged.
• Deducting for items the tenancy agreement never made the tenant responsible for.

Practical guidance

• Quote the clause of the tenancy agreement that supports each deduction.
• Pair every check out photograph with the matching check in photograph.
• Provide invoices or written quotes rather than estimated figures.
• Apply a fair depreciation reduction yourself before claiming, because it reads as reasonable.

How adjudicators weigh the evidence

The adjudicator works through each head of claim in turn. They ask whether the tenancy agreement makes the tenant responsible, whether the check in record shows the original condition, whether the check out record shows the damage, whether the damage goes beyond fair wear and tear and whether the amount claimed is reasonable and evidenced. A claim can fail at any of those five stages. Landlords often have strong evidence on stages three and five while missing stages one and two entirely.

Timescales and what to expect

Once both parties have submitted, decisions typically arrive within a few weeks. The scheme sets a deadline for evidence and it is strict, so prepare your bundle before you start the process rather than during it. Keep submissions organised by room and by head of claim, with a short covering summary showing the amount claimed for each item. A clear bundle is genuinely more persuasive than a large one.
