How to Manage the 28-Day and 35-Day Deposit Deadlines in Northern Ireland Without Missing One

If you are a self-managing landlord in Northern Ireland trying to keep track of two deposit deadlines that start on the same day but expire a week apart, the approach that works is to treat them as a single compliance sequence rather than two independent timers. Protect the deposit within 28 calendar days, then serve prescribed information (with the scheme leaflet) by day 35. Do them in order, document both, and file the evidence together. The moment you treat them as separate administrative tasks that can be handled whenever, one of them gets missed.

Here is how the dual deadline system works and a practical method for managing it without an agent or property management software.

The Two Deadlines Explained

Both clocks start on the same day — the day you receive the tenancy deposit. They run to different endpoints.

Deadline 1 — Deposit Protection (28 calendar days) You must register the deposit with one of Northern Ireland's two approved schemes: TDS Northern Ireland or mydeposits Northern Ireland. This means the deposit is either held by the custodial scheme or insured through the insured scheme, and the registration is confirmed.

Deadline 2 — Prescribed Information (35 calendar days) You must serve the tenant with a package of prescribed information: the details required under Schedule 1 of the Tenancy Deposit Schemes Regulations (Northern Ireland) 2012, plus the scheme leaflet from whichever scheme you registered with. Both documents must reach the tenant, and you must be able to prove delivery.

These are separate statutory duties. Protecting the deposit on day 27 but serving prescribed information on day 36 is a breach. Serving prescribed information on day 30 but not protecting the deposit until day 29 is also a breach. Each has its own enforcement consequences.

Why This Catches Landlords Out

The dual deadline is a Northern Ireland peculiarity that does not exist in the same form elsewhere in the UK. In England, the protection deadline and the prescribed information deadline are both 30 days — same clock, same endpoint. A landlord who protects the deposit on day 28 has automatically met both deadlines.

In Northern Ireland, the staggered deadlines create a week where one duty is done and the other is not. Landlords who protect the deposit on day 25 and then relax because "the deposit is sorted" forget that prescribed information has a separate deadline that is still running. The seven-day gap between the two deadlines is exactly enough time to feel like the job is finished when it is only half done.

The penalty structure makes this more than a technicality. A council Environmental Health officer checking compliance will verify both: (1) was the deposit registered in time, and (2) was prescribed information served in time. Failing either one independently triggers enforcement. A fixed penalty notice for deposit protection failure can be up to three times the deposit. A separate penalty may apply for prescribed information failure. Since the Private Tenancies Act (NI) 2022, these are continuing offences — there is no limitation period on enforcement.

A Practical System for Tracking Both

You do not need property management software. You need a dated sequence and a filing method.

Step 1: Record the Deposit Receipt Date

The moment a tenant hands over the deposit — by bank transfer, cheque, or cash — write down the date. This is Day 0. Both clocks start here. If you accept the deposit via an agent who then transfers it to you, the clock started when the agent received it, not when you did.

Step 2: Calculate Both Deadlines

Count 28 calendar days from Day 0 for the protection deadline. Count 35 calendar days from Day 0 for the prescribed information deadline. Put both dates somewhere you will see them — a calendar reminder, a sticky note on your landlord file, the top of a compliance checklist.

For a deposit received on 15 November 2026:

• Protection deadline: 13 December 2026 (28 days)
• Prescribed information deadline: 20 December 2026 (35 days)

Step 3: Protect the Deposit (Aim for Week 2, Not Week 4)

Register the deposit with TDS Northern Ireland or mydeposits Northern Ireland as early as possible. The scheme gives you a deposit protection certificate and reference number. Do not wait until day 27.

Aiming for week 2 (days 7–14) gives you a buffer for any scheme processing delays, bank transfer hold-ups, or errors in the registration form. Landlords who protect on day 26 and discover an error on day 27 have no margin.

Step 4: Prepare Prescribed Information During the Protection Wait

While the deposit registration processes, prepare the prescribed information package:

• The Schedule 1 information (deposit amount, scheme name, scheme contact, tenancy address, landlord details, and all other prescribed fields)
• The scheme leaflet (each approved scheme publishes its own — download it from the scheme's website after registration)
• A delivery record (not provided by either scheme — you need to create one that captures the date, method, and acknowledgment of delivery)

Step 5: Serve Prescribed Information and Document Delivery

Once the deposit protection certificate is in hand, serve the prescribed information package to the tenant. The 35-day deadline gives you seven days after the protection deadline, but do not use all of it. Serve within a few days of protecting the deposit — ideally in the same meeting or post.

The delivery record is the critical document. If a council ever investigates, you need to prove that prescribed information was served within 35 days. A signed-and-dated delivery record — stating what was served, when, and how — is your evidence. Hand delivery with a signature is strongest. Email or post with a follow-up confirmation is acceptable. A verbal "I told them" with no documentation is not.

Step 6: File Everything Together

One physical or digital folder per tenancy containing:

• Deposit receipt confirmation (date, amount, method)
• Both deadline dates (written out, not just in your head)
• Deposit protection certificate from the scheme
• Copy of the prescribed information served
• Copy of the scheme leaflet served
• Signed delivery record with date

This folder is your compliance file. If a council officer asks for evidence two years later, everything is in one place.

The Mid-Tenancy Trap

The 28/35-day deadlines can apply again when a landlord receives additional deposit money. Under Article 5B(3) of the 2006 Order, a top-up deposit has its own 28-day protection clock and 35-day prescribed-information duty. This happens when:

• Rent increases and you take a top-up deposit to match the new one-month cap
• A joint tenant leaves and a new tenant joins, paying fresh deposit money
• A fixed-term tenancy ends and a new tenancy starts with an existing deposit carried over; this is a retention, so review the cap under Article 5ZD and update scheme details and prescribed information as required

New deposit money paid by a replacement joint tenant triggers deadlines for that amount; a transfer of an existing deposit on renewal does not itself restart the protection clock. Variations should be reflected in the scheme registration, and updated prescribed information served when required.

The Tenancy Deposits in Northern Ireland guide includes a compliance timeline tool that maps both deadlines on a single calendar view and covers top-ups, joint-tenant changes, and renewal scenarios that catch landlords who thought the initial protection was the only step.

Frequently Asked Questions

What happens if I protect the deposit on time but serve prescribed information late?

Each duty is assessed independently. You have met the deposit protection obligation but breached the prescribed information obligation. The council can issue a fixed penalty notice for the prescribed information breach alone. The penalties are separate — compliance on one does not excuse failure on the other.

Can I serve prescribed information before the deposit is protected?

Technically, the 35-day clock runs from deposit receipt regardless of when you protect. But the prescribed information must include the deposit protection certificate number and the scheme's contact details — information you only have after protection is confirmed. In practice, you protect first, then serve prescribed information with the certificate details included.

Do I need to track these deadlines if I use a letting agent?

Your agent should handle both deadlines, but you are legally responsible for compliance. If you use a full-management agent, ask for copies of the deposit protection certificate and the prescribed information delivery record, with dates. Verify that both were completed within the statutory deadlines. If the agent missed a deadline, the enforcement action comes to you.

Is there a penalty for protecting the deposit one day late — on day 29 instead of day 28?

Yes. The 28-day deadline is absolute. Day 29 is a breach, regardless of the reason. Councils do not have a discretionary grace period. Fixed penalty notices can be up to three times the deposit for late or missing protection. The fact that you were only one day late does not reduce the penalty.
