Northern Ireland Tenancy Deposit Laws: Limits, Protection Schemes, and Deadlines

Holding a tenant's deposit in Northern Ireland is heavily regulated. The Private Tenancies Act (NI) 2022 introduced strict financial caps, while existing regulations mandate rigid timelines for protecting the money in approved schemes.

The 1-Month Deposit Limit

Since April 1, 2023, under the Private Tenancies Act 2022, a landlord or letting agent cannot ask for or retain a tenancy deposit that is more than one month's rent.

• If a tenant's rent is £800 a month, the maximum deposit is £800.
• It is a criminal offence to ask for a deposit exceeding this limit.
• If a tenant paid a higher deposit before April 1, 2023, the landlord may retain it until the end of that specific tenancy agreement, but new agreements must comply with the cap.

Mandatory Deposit Protection

Any deposit taken for a private tenancy must be protected in an approved Tenancy Deposit Scheme (TDS). There are two types of schemes:

1. Custodial scheme: The scheme holds the money for free.
2. Insurance scheme: The landlord holds the money but pays a fee to the scheme to insure it.

Approved scheme operators in Northern Ireland include TDS Northern Ireland, My Deposits NI, and Letting Protection Service NI.

Critical Deadlines

The law imposes strict deadlines on landlords from the moment they receive the deposit money:

The "Prescribed Information" is a specific document detailing how much was paid, which scheme is securing it, and how the protection works.

Penalties for Missing Deadlines

The Private Tenancies Act 2022 removed the 6-month time limit for prosecuting deposit offences, making a failure to protect a deposit a continuing offence. Local councils can issue heavy fixed penalty notices or prosecute landlords in court for failing to meet the 28-day or 35-day deadlines.

Permissible Deductions

At the end of the tenancy, the landlord can request deductions from the deposit for:

• Unpaid rent or rates.
• Damage to the property beyond normal wear and tear.
• Missing inventory items.
• Cleaning costs (if the property was not left in the condition it was provided).

Deductions cannot be made for standard normal wear and tear.

Dispute Resolution

If the landlord and tenant disagree on the deductions, the approved Tenancy Deposit Scheme provides a free, independent dispute resolution mechanism. An adjudicator will review evidence (like the tenancy agreement, check-in/check-out inventories, and photos) and make a binding decision on how the deposit should be split.
