Deposit Deductions in Wales: Rules for End-of-Contract Returns

Deductions Must Be in the Contract

A landlord in Wales can only deduct from a security deposit for reasons explicitly set out in the written terms of the occupation contract. Common lawful deduction categories include:

• Unpaid rent or utility charges owed under the contract terms
• Physical damage to the property, fixtures, or fittings caused by breach of the contract-holder's duties
• Cleaning necessary to restore the property to the standard documented at check-in

If the occupation contract's written statement does not include a clause permitting a specific type of deduction, the landlord has no contractual basis to claim it — even if the damage is real.

Fair Wear and Tear

The single most common dispute point. Landlords cannot deduct for the natural deterioration of the property through ordinary use. Carpets lose pile, walls scuff at switch height, grouting discolours, and paint fades. These are fair wear and tear.

Damage beyond normal use — a burn hole in a carpet, a cracked window, a stained bathtub from hair dye — is not fair wear and tear and can be the basis for a deduction, provided the check-in inventory proves the item was in better condition at the start.

The Betterment Rule

An adjudicator will never award the full replacement cost of an old item. The principle is that a landlord should not profit from a deduction by receiving a brand-new replacement for something that was already partially worn.

Deductions are calculated based on:

• The item's age and original condition at check-in
• The item's expected useful lifespan
• The remaining life the item would have had without the damage

A five-year-old carpet with an expected ten-year lifespan that is destroyed by the contract-holder would justify a deduction of roughly half the replacement cost — not the full price of a new carpet.

Return Timeline

Once the landlord and contract-holder agree on deductions (or agree there are none), the undisputed deposit should be returned within 10 calendar days. This timeline comes from the operational rules of the authorised schemes, not from primary legislation, but it is the standard the schemes enforce.

If only part of the deposit is in dispute, the undisputed portion must be released immediately. A landlord who holds back the full deposit while negotiating over a £150 cleaning claim is acting outside the scheme's rules.

Proposing Deductions

After the check-out, the practical sequence is:

1. Compare check-in and check-out records — identify specific items where the condition has deteriorated beyond fair wear and tear
2. Calculate each deduction — based on repair or cleaning costs, adjusted for the item's age and remaining useful life
3. Write to the contract-holder — list each proposed deduction with the amount, the reason, and the supporting evidence (photos, invoices, quotes)
4. Allow time for response — the contract-holder may agree, negotiate, or dispute
5. Release undisputed funds — transfer the agreed portion within 10 days of agreement

If agreement cannot be reached, either party can raise the dispute through the scheme's ADR process at no cost.

Prohibited Cleaning Clauses

Under the Renting Homes (Fees, Discrimination etc.) (Wales) Act 2019, requiring professional end-of-tenancy cleaning as a mandatory contract term is an illegal prohibited payment. The legal standard is that the contract-holder returns the property in a hygienic state comparable to the condition documented at check-in. Whether a professional cleaner or the contract-holder personally achieves that standard is irrelevant.

The Wales deposit protection guide includes a deductions calculator worksheet and a deduction letter template for communicating proposed deductions clearly.
