NI Tenancy Deposits — Protect, Prove, Return

You Have 28 Days. The Clock Started When You Took the Deposit.

Every private landlord in Northern Ireland who accepts a tenancy deposit triggers two statutory deadlines. You have 28 calendar days to protect the deposit in an approved scheme and 35 calendar days to serve the prescribed information to your tenant. Miss either one and your local council can issue a fixed penalty notice or prosecute — and since April 2023, deposit failures are continuing offences with no time bar on enforcement.

The problem is that almost everything you read online is written for England. English rules say 30 days and five weeks' rent. Northern Ireland says 28 days and one month's rent. English rules give tenants a court claim for one to three times the deposit. Northern Ireland gives councils prosecution powers and fixed penalty notices of up to three times the deposit. A landlord following the wrong country's template is not just slightly off — they are breaking the law they do not even know applies to them.

The Deposit Compliance System

This guide replaces five government websites, two scheme portals, and a scattered collection of generic UK landlord advice with a single document that follows the deposit from the day you take it to the day you return it.

It is built exclusively for Northern Ireland. Every deadline, every form reference, every penalty figure, every scheme comparison, and every worked example uses Northern Ireland's own statute — the Private Tenancies (NI) Order 2006 as amended by the Private Tenancies Act (NI) 2022 — verified as of October 2026.

What's Inside

• The 28-day and 35-day deadline system — both clocks mapped out on a single timeline so you never confuse which duty is due when, with a worked example showing exactly what happens at each step
• The one-month rent cap with conversion formulas — how to calculate the maximum deposit when rent is weekly, fortnightly, or four-weekly, because four weeks is not one month and getting it wrong is a £500 fixed penalty
• Scheme comparison: TDS NI vs mydeposits NI — custodial and insured options side by side, with the fees, payout timelines, and practical differences that matter when choosing
• The prescribed information requirements — exactly what you must hand to the tenant, the scheme leaflet that goes with it, and how to create a proof-of-delivery record that survives a dispute
• Mid-tenancy compliance — what happens to the deposit when rent changes, a joint tenant leaves, you inherit a tenancy from an agent, or you renew a fixed term: the Notice of Variation rules and the 28-day duty that most landlords miss
• End-of-tenancy returns and deductions — the agreed-return process, the disputed-deduction process, what evidence adjudicators actually require, and the ADR timeline from claim to decision
• Penalties and enforcement — fixed penalty notices of £500 or up to three times the deposit for each breach, council prosecution with fines up to £2,500 per offence, and the continuing-offence rule that removes any time bar on enforcement
• A 24-item compliance checklist — six phases from deposit receipt through return, each item cross-referenced to the guide chapter that explains it
• Six fillable compliance tools — a 28/35-day deadline timeline, deposit receipt log, prescribed information delivery record, room-by-room inventory template, deduction schedule, and tenancy variation record, all printable and ready to file with your tenancy records

Who This Guide Is For

You are a self-managing private landlord in Northern Ireland with one to a few residential properties. You take deposits directly, handle tenant handovers yourself, and need structured compliance records — not scattered advice across multiple websites.

This guide is for landlords who want to get it right the first time: accept the deposit, protect it correctly, serve the paperwork on time, document everything, and return the deposit without a dispute at the end.

Why Not Free Resources?

The official information exists. nidirect explains the 28-day rule. TDS Northern Ireland and mydeposits NI publish their own forms. Your local council's Environmental Health page lists the penalties. The Department for Communities has policy guidance.

What none of them provide is a single, chronological workflow. You have to stitch together five different sources, work out which deadlines overlap, figure out the mid-tenancy obligations on your own, and hope you have not accidentally followed an English rule. Self-managing landlords routinely confuse Landlord Registration (which does not protect a deposit) with deposit scheme registration (which does). They follow English 30-day templates and breach the 28-day deadline. They serve the prescribed information late because they assumed it shared the same clock as protection.

This guide puts the sequence in order, provides the templates for proving delivery, and flags every point where Northern Ireland diverges from the English rules that dominate online search results.
