Northern Ireland Private Tenancies Act 2022: Deposit Rules

The Act That Rewrote NI Deposit Law

The Private Tenancies Act (Northern Ireland) 2022 received Royal Assent on 27 April 2022, but its deposit provisions did not take effect until 1 April 2023, when the relevant sections were brought into force by Commencement Order S.R. 2023/20. The changes were significant — not incremental tweaks but structural overhauls to how deposit compliance works in Northern Ireland.

If you are a landlord operating under rules you learned before April 2023, several of your assumptions are now wrong.

What Changed on 1 April 2023

The deposit cap: A new statutory ceiling of one month's rent on all tenancy deposits. Before the 2022 Act, there was no specific cap in Northern Ireland. Landlords routinely took five or six weeks' rent as a deposit. That is now illegal. The cap was inserted as Article 5ZC into the Private Tenancies (Northern Ireland) Order 2006.

The protection deadline: Extended from 14 calendar days to 28 calendar days. This sounds more generous, but the old 14-day rule was rarely enforced. The 28-day rule comes with teeth — see continuing offences below.

The prescribed information deadline: Extended from 28 calendar days to 35 calendar days. A separate, independent deadline that runs alongside the protection clock.

Continuing offences: Failure to protect a deposit or serve prescribed information was reclassified from a standard summary offence (with a six-month prosecution window) to a continuing offence. The breach is committed every day until rectified. District councils can now investigate and penalise breaches that are months or years old, as long as the deposit remains unprotected. This is the change with the sharpest practical impact.

The Transitional Rules for Pre-2023 Deposits

Deposits taken before 1 April 2023 were not automatically affected by the new cap. A deposit of £1,200 on a £900/month tenancy was lawful before the cap existed and remained lawful as long as the original tenancy continued uninterrupted.

But under Article 5ZD, if the first tenancy ends and a new tenancy is granted on or after 1 April 2023, any part of the old deposit that continues to be held in connection with the new tenancy becomes a statutory "retention." The one-month cap applies to that retention, and any excess above the new tenancy's monthly rent is recoverable by the person who paid it.

This can affect landlords who grant a new tenancy after April 2023 without reviewing their deposit holdings. If the deposit is carried over, any excess remains recoverable by the person who paid it.

How This Interacts With Other 2022 Changes

The Private Tenancies Act 2022 did more than deposit reform. Other provisions affect landlords at the same time:

• Tenancy Information Notice (TIN): Section 1 requires landlords to serve a TIN within 28 days of the tenancy starting, alongside the deposit protection deadline
• EICR requirement: All rented properties must have a valid Electrical Installation Condition Report by 1 December 2025 (already in force)
• Cash receipt obligations: Strengthened requirements for issuing written receipts for cash payments
• Extended notice periods: Section 11 introduced graduated Notice to Quit lengths — 4 weeks for tenancies under 12 months, 8 weeks for 1 to 10 years, 12 weeks for over 10 years

A landlord dealing with a new tenancy start faces multiple overlapping deadlines. The deposit protection period (28 days) and prescribed-information period (35 days) start on the date the deposit is received; the Tenancy Information Notice is due within 28 days of the tenancy being granted. When the deposit is received at the start of the tenancy, these periods run concurrently.

The Enforcement Landscape in 2026

Northern Ireland's 11 district councils enforce the 2022 Act through their Environmental Health departments. The statutory penalties depend on the breach:

• Deposit above the one-month cap: council-set Fixed Penalty Notice up to £500; summary fine up to £2,500. The court may order the excess repaid to the person who paid it.
• Failure to protect or serve prescribed information: Fixed Penalty Notice equal to three times the deposit; summary fine up to £20,000. These failures are continuing offences, with no six-month time limit while they continue.
• Impaired eviction rights until the breach is rectified

Councils have been actively issuing fixed penalties for deposit breaches since April 2023. The continuing-offence provision means that a deposit taken in 2020 and never protected is still a live, prosecutable offence today.

What Landlords Must Do Now

If you have any tenancy where the deposit was not protected within 28 days, protect it immediately. Late protection stops the continuing offence clock. If you have any tenancy where you never served prescribed information, serve it now.

If you hold any deposit that exceeds one month's current rent and the tenancy has been renewed or varied since April 2023, return the excess to the tenant and update the scheme registration.
