Wales Residential Security Deposit Laws

Disclaimer: This guide provides general legal information for educational purposes only and does not constitute legal advice. Always consult a qualified solicitor in Wales for advice specific to your situation. Information last verified: March 2026.

Handling security deposits (often referred to simply as "deposits") in Wales is strictly regulated by two primary pieces of legislation: The Renting Homes (Fees etc.) (Wales) Act 2019, which caps the amount, and the rules carrying over into the Renting Homes (Wales) Act 2022 requiring mandatory protection.

In Wales, tenants are legally known as contract-holders.

Security Deposit Caps

Under the Renting Homes (Fees etc.) (Wales) Act 2019, a landlord cannot ask a contract-holder for an unlimited deposit.

• Standard Cap: The maximum security deposit a landlord can require is equivalent to 5 weeks' rent.
• High-Rent Cap: If the total annual rent for the property exceeds £50,000, the landlord may request a deposit equivalent to 6 weeks' rent.

It is illegal to ask for a deposit consisting of physical belongings (like a watch or car); the deposit must be monetary or a formal guarantee.

Mandatory Tenancy Deposit Protection Schemes

A landlord cannot simply hold the security deposit in their personal or business bank account. By law, the deposit must be "protected" in a government-authorized Tenancy Deposit Protection (TDP) scheme.

The 30-Day Deadline

Once a landlord (or their letting agent) receives the deposit from the contract-holder, they have exactly 30 days to:

1. Protect the money in an authorized TDP scheme (such as the Deposit Protection Service, MyDeposits, or the Tenancy Deposit Scheme).
2. Provide the contract-holder with the "Prescribed Information." This is a formal document detailing exactly which scheme holds the money, the scheme's contact details, and the procedures for retrieving the deposit at the end of the contract.

Penalties for Failing to Protect the Deposit

If a landlord misses the 30-day deadline—even by one day—the consequences are severe:

• The landlord is legally barred from issuing a "no-fault" eviction notice to reclaim the property.
• The contract-holder can take the landlord to the County Court. The judge must order the landlord to repay the original deposit, plus a penalty of between one and three times the deposit amount.

Holding Deposits

Before an occupation contract is signed, a landlord can ask for a "holding deposit" to reserve the property.

• The Cap: A holding deposit is strictly capped at 1 week's rent.
• The 15-Day Rule: Once the holding deposit is paid, the landlord and contract-holder have 15 days to enter into an occupation contract.
• Refund: If the contract is signed, the holding deposit must be refunded within 7 days (or, as is common practice, put toward the first month's rent or the main security deposit). If the landlord backs out, it must be refunded. The landlord can only keep the holding deposit if the contract-holder backs out, provides false information, or fails a Right to Rent check.

Returning the Deposit

When the occupation contract ends, the landlord and contract-holder must agree on any deductions (e.g., for unpaid rent or damage beyond normal wear and tear).

• If both parties agree, the TDP scheme will release the funds, usually within 10 days.
• If there is a dispute over deductions, the funds remain protected in the scheme, and both parties must use the scheme's free alternative dispute resolution (ADR) service to settle the matter without going to court.

How Landager Helps Landlords in Wales

Missing the 30-day deposit protection deadline is the most common and costly mistake landlords make in Wales. Landager's compliance dashboard actively tracks the exact minute a holding or security deposit is logged in the system. It triggers automated priority alerts counting down the 30-day protection window, and can automatically generate and email the required Prescribed Information packet to the contract-holder, ensuring you remain immune to court penalties and eviction blockages.
