The 30-day deposit rule: how to protect a deposit correctly

Tenancy deposits look simple on the surface: collect the money, keep it safe, hand it back at the end. In practice, they are one of the most litigated areas of landlord-tenant law in England and Wales — and almost always because a landlord missed a deadline or skipped a piece of paperwork. The 30-day rule is the heartbeat of the whole system. Miss it, and you are exposed to a penalty of up to three times the deposit, you can lose the ability to recover possession through most Section 8 grounds, and there is no get-out clause for an honest mistake. This guide explains exactly what the law requires, where landlords routinely trip up, and how to build a process that means the clock is never missed.

What the 30-day rule actually means

Under section 213 of the Housing Act 2004, any deposit paid under an assured shorthold tenancy (AST) in England and Wales must be protected in a government-authorised scheme within 30 days beginning with the date the landlord or agent receives the funds. The same 30-day window applies to serving the prescribed information — the written documentation that tells the tenant which scheme holds their money, how to access it, and how disputes are resolved.

Two points that regularly catch people out:

The clock starts at receipt, not at the tenancy start date. If a tenant pays a deposit four weeks before moving in, the 30-day countdown starts from the day the money is received — not the date the tenancy commences. A deposit received on 1 March for a tenancy starting 1 May must be protected by 30 March.

Both obligations fall within the same window. Protecting the deposit with a scheme is one step; serving the prescribed information is a separate legal duty under sections 213(5) and 213(6) of the Housing Act 2004. Many landlords protect promptly but delay sending the paperwork, and that omission is treated as a separate breach.

The three approved schemes

Every deposit must go into one of three government-approved schemes:

• Deposit Protection Service (DPS) — custodial and insured options
• MyDeposits — custodial and insured options
• Tenancy Deposit Scheme (TDS) — custodial and insured options

All three now offer both models. With a custodial scheme the scheme holds the money (usually free). With an insured scheme you hold the funds and pay a fee for the scheme’s insurance-backed guarantee. Neither is inherently better — the right choice depends on your cash-flow preferences and whether you use a managing agent. What matters is that you use one of these three and can prove it.

At PropertyGoose, deposit registration is handled as part of the same referencing and tenancy setup flow, so the scheme is registered before a tenancy agreement is even issued — eliminating the gap between referencing and compliance.

What prescribed information must include

Serving the deposit certificate alone is not enough. The prescribed information must cover:

• The name and contact details of the scheme administrator
• The deposit amount and the address of the property
• The landlord’s (or agent’s) name and contact details
• A summary of the circumstances in which the deposit may be retained
• The tenant’s right to dispute deductions through the scheme’s free Alternative Dispute Resolution (ADR) service
• What happens if either party cannot be contacted at the end of the tenancy

Every tenant named on the agreement must receive this. If a parent or guarantor contributed the deposit as a “relevant person”, best practice is to serve them too.

What happens if you miss the deadline

The sanctions sit under section 214 of the Housing Act 2004. Once a court finds a breach, it must order the landlord to pay the tenant compensation of between one and three times the deposit amount — the award itself is mandatory, though the multiple within that band is at the court’s discretion (judges often look hardest at how blameworthy the landlord was). Where the tenancy is ongoing, the court must also order the deposit to be repaid to the tenant or paid into a custodial scheme; once the tenancy has ended, repayment of the deposit is discretionary.

For a £1,500 deposit, a maximum award means the tenant receives £4,500 in compensation. Tenants generally have six years to bring a claim, meaning a missed deadline from years ago can surface long after the tenancy ended.

The implications for possession are equally serious. Under the Renters’ Rights Act 2025, whose first phase took effect on 1 May 2026, Section 21 no-fault evictions were abolished. More immediately relevant for deposit compliance: a court may not grant possession under most Section 8 grounds unless the deposit is held in an authorised scheme (the anti-social behaviour grounds 7A and 14 are exceptions). A landlord owed rent arrears whose deposit was never properly protected risks a counterclaim being set off against those arrears.

See how PropertyGoose pricing works on the pricing page — referencing, deposit registration, and tenancy agreements are bundled into a single per-tenancy workflow.

The deposit cap: how much can you hold?

Under the Tenant Fees Act 2019, the maximum deposit is:

• Five weeks’ rent where the total annual rent is below £50,000
• Six weeks’ rent where the total annual rent is £50,000 or more

This cap applies whether or not you use a managing agent, and applies per tenancy rather than per tenant. Holding more than the permitted amount is a prohibited payment, with a first-offence financial penalty of up to £5,000 (rising to £30,000 or prosecution for a repeat breach within five years).

Deductions: what you can and cannot claim

At the end of the tenancy, permitted deductions are:

• Unpaid rent (with a clear paper trail)
• Damage beyond fair wear and tear (supported by check-in and check-out reports and repair quotes)
• Cleaning where the tenant left the property materially below the standard at the start (with invoices)
• Unpaid bills attributable to the tenant

You cannot deduct for fair wear and tear, general maintenance, redecoration that was already overdue, or your own administrative time. The cleaner and more detailed your inventory — with timestamped photos and a signed check-in — the stronger your position in any dispute.

Building a process that never misses the clock

The most common source of late protection is not malice; it is a gap between the moment funds arrive and the moment anyone logs in to register them. A reliable process has three steps that happen in sequence:

1. Confirm receipt of cleared funds — do not protect a pending payment; wait for it to clear.
2. Register with the scheme the same day — set a diary reminder the moment the money arrives.
3. Serve the prescribed information immediately — send it to all tenants and keep a delivery record.

At PropertyGoose, steps two and three are triggered as part of the tenancy setup flow, and a compliance log is retained for both landlords and agents. Book a demo to see how it works in practice.

A quick compliance checklist

• Deposit received and cleared
• Protected with DPS, MyDeposits, or TDS within 30 days of receipt
• Deposit does not exceed five (or six) weeks’ rent
• Prescribed information served to all tenants within 30 days
• Confirmation of protection retained (certificate or reference number)
• Check-in inventory completed and signed
• Records stored — claims can arise up to six years later

The 30-day rule is not complicated. What makes it dangerous is how easy it is to treat deposit registration as an afterthought. The legislation does not allow for that. Building deposit protection into the very first step of your tenancy workflow is the only reliable way to stay compliant — and platforms like PropertyGoose are designed to make that the default, not an extra task on a to-do list.
