Deposit Protection: The 30-Day Rule for Landlords

Tenancy deposit protection has been mandatory in England and Wales since 2007. Despite nearly two decades of the rules being in force, deposit protection failures remain one of the most common landlord compliance mistakes, often with severe consequences. This guide explains the 30-day deadline, the three approved schemes, prescribed information requirements, and critically, how to prove you complied.

Why Deposit Protection Exists

Tenancy deposit protection schemes were introduced to address a long-standing problem: disputes over deposit returns at the end of tenancies. Before 2007, landlords held deposits directly. When tenancies ended, disagreements over deductions were common and difficult to resolve.

The deposit protection system serves two purposes. First, it safeguards tenant money by holding it in an independent scheme. Second, it provides free Alternative Dispute Resolution (ADR) if landlord and tenant disagree about deductions at the end of the tenancy.

The rules are strict because deposits are often tenants' largest financial commitment when renting. Failing to protect a deposit correctly can result in penalties of one to three times the deposit amount, paid to the tenant, plus loss of the ability to use Section 21 eviction (or equivalent grounds under the Renters' Rights Act 2025).

The Three Approved Schemes

Only three tenancy deposit protection schemes are approved for use in England and Wales. You must use one of these. Any other arrangement is not legally compliant.

Deposit Protection Service (DPS). Run by Computershare. Offers both custodial (they hold the deposit) and insured (you hold the deposit but pay insurance) options. The custodial option is free. Website: depositprotection.com

MyDeposits. Run by Tenancy Deposit Solutions Ltd. Offers both custodial and insured schemes. Charges apply for the insured option. Website: mydeposits.co.uk

Tenancy Deposit Scheme (TDS). Offers both custodial and insured options. Charges for insured, free for custodial. Website: tenancydepositscheme.com

All three schemes provide the same essential service: holding or insuring the deposit and offering dispute resolution. The choice between them is mainly about personal preference, though some letting agents have preferred schemes.

Scotland has separate schemes: SafeDeposits Scotland, MyDeposits Scotland, and Letting Protection Service Scotland. Northern Ireland has the Tenancy Deposit Scheme Northern Ireland.

Custodial vs Insured Schemes

You must choose between custodial and insured protection. Both are legally compliant but work differently.

Custodial scheme: You transfer the deposit to the scheme. They hold it until the end of the tenancy. When the tenancy ends, both parties agree how to divide it, or the scheme's ADR service decides if there's a dispute. Custodial protection is free.

The advantage is no cost and complete impartiality. The disadvantage is you don't have access to the deposit money during the tenancy.

Insured scheme: You keep the deposit in your own bank account but pay the scheme to insure it. At the end of the tenancy, you handle the return yourself if there's agreement, or submit the disputed amount to ADR if needed. Insured schemes charge a fee, typically £20-30 per tenancy.

The advantage is you retain access to the money and potential interest. The disadvantage is cost and you must handle returns proactively.

Most landlords with smaller portfolios use custodial schemes to avoid cost. Larger landlords or professional landlords sometimes prefer insured schemes for cash flow reasons.

The 30-Day Deadline

This is the critical compliance requirement. You must protect the deposit in an approved scheme within 30 days of receiving it. The clock starts when the deposit is paid to you, not when the tenancy begins.

If a tenant pays a deposit on 1 February, you must protect it by 3 March (30 days later). If the tenancy doesn't start until 15 February, the deadline remains 3 March based on when you received the money.

The 30-day deadline is absolute. “I forgot” or “I was busy” are not defenses. If you protect the deposit on day 31, you've failed to comply.

For custodial schemes, “protected” means the scheme has received and confirmed they hold the deposit. For insured schemes, it means you've registered the deposit with the scheme and paid any required fees.

Prescribed Information Requirements

Protecting the deposit is not the only requirement. You must also provide the tenant (and anyone else who paid the deposit) with prescribed information within 30 days of receiving the deposit.

Prescribed information is a specific set of details about the deposit protection. The scheme provides a template document. It must include the amount of the deposit, the address of the property, the name and contact details of the landlord, the name and contact details of the tenant, the name and contact details of the scheme, information about how the deposit is protected, details of how to apply for the deposit to be released, and information about the dispute resolution service.

You cannot write your own prescribed information document. You must use the template provided by the scheme you're using. Each scheme has slightly different wording, so match the document to the scheme.

The 30-day deadline for providing prescribed information runs parallel to the 30-day protection deadline. Both must be completed within 30 days of receiving the deposit. Protecting the deposit but failing to provide prescribed information is non-compliance.

And crucially, you must prove you provided it. Simply generating the document is not enough. Our guide on proving tenants received documents explains the evidence you need.

Penalties for Non-Compliance

The penalties for failing to protect a deposit or provide prescribed information correctly are severe and intended to be punitive.

Financial penalty. If you fail to comply, the tenant can take you to court. The court must order you to pay the tenant between one and three times the deposit amount. This is in addition to returning the deposit itself.

For example, if the deposit was £1,000 and you failed to protect it properly, you must return the £1,000 deposit and pay the tenant an additional £1,000 to £3,000 penalty. The court has discretion on the exact amount within that range based on the severity of the breach.

There is no time limit for tenants to claim this penalty while the tenancy exists. A tenant could wait years, then claim just before moving out.

Loss of possession rights. Before the Renters' Rights Act 2025, failing to protect the deposit properly prevented you from using Section 21 no-fault eviction. Under the new Act, deposit protection compliance is a prerequisite for several possession grounds. If you haven't protected the deposit correctly, you cannot regain possession even if the tenant is in serious arrears.

Our article on Section 8 eviction grounds explains how compliance failures can block possession claims under the new system.

Common Deposit Protection Mistakes

Despite the rules being clear, certain mistakes happen repeatedly. Being aware of them helps you avoid them.

Missing the 30-day deadline. The most common error. Landlords receive the deposit and intend to protect it but delay. By the time they act, it's day 35 or 40. Too late.

Protecting but not providing prescribed information. Landlords protect the deposit in a scheme but forget to send the tenant the prescribed information document. Both steps are required.

Providing prescribed information but no proof. The landlord emails the document but doesn't keep the sent email or any proof the tenant received it. Later, the tenant claims they never received it, and the landlord cannot prove otherwise.

Using the wrong scheme's prescribed information. Landlord protects the deposit with DPS but sends the MyDeposits prescribed information document. The information must match the scheme actually used.

Not protecting top-up deposits. If the tenant pays an additional deposit mid-tenancy (for example, to keep a pet), that additional amount must also be protected within 30 days and prescribed information provided again.

Holding money outside the scheme. Landlord uses an insured scheme but deducts money before the end of tenancy without agreement or adjudication. You cannot take money from an insured deposit unilaterally. If there's a dispute, it must go through the ADR process.

Proving You Provided Prescribed Information

This is where many landlords fail. The law requires you to provide prescribed information, but in practice, you must prove you provided it.

If a tenant claims in court that they never received prescribed information, the burden is on you to prove they did. “I definitely sent it” is not proof.

Weak evidence: No record of sending it, or claiming you handed it to them in person but they didn't sign an acknowledgement.

Better evidence: Email showing you sent it within 30 days. Keep the sent email with the prescribed information attached. This proves you sent it but doesn't guarantee the tenant received or opened it.

Best evidence: Digital platform tracking showing the tenant accessed the document. A log showing they opened the prescribed information on a specific date within the 30-day window is compelling proof.

Alternatively, registered post with signed receipt. The tenant signs to confirm delivery. Keep that signature proof.

Many landlords hand prescribed information to tenants at the start of the tenancy along with other documents. Get them to sign an acknowledgement listing all documents received. Keep that signed acknowledgement for the duration of the tenancy plus six years after it ends.

Deposit Returns and Disputes

At the end of the tenancy, the deposit must be returned or deductions justified. This is where the protection scheme's dispute resolution service becomes valuable.

If you and the tenant agree on how to divide the deposit, simply process the agreed return. For custodial schemes, both parties confirm agreement and the scheme releases the money accordingly. For insured schemes, you return the agreed amount and notify the scheme.

If you disagree, either party can raise a dispute with the scheme's ADR service. Both parties submit evidence (inventory, check-out report, photos, invoices for cleaning or repairs). An independent adjudicator reviews the evidence and decides how to divide the deposit.

The adjudication is free, binding, and usually completed within a few weeks. It's much faster and cheaper than court. This is why deposit protection exists: to provide fair, quick resolution of deposit disputes.

To maximize your chances in a dispute, you need evidence. A detailed inventory and schedule of condition at the start, a thorough check-out report at the end, and contemporaneous records of the property's condition. Our guide on end of tenancy documentation covers what you need.

Deposits for HMOs and Multiple Tenants

HMOs with multiple tenants on separate agreements can create deposit protection complexity, but the principles remain the same.

If each tenant has a separate tenancy agreement and pays a separate deposit, you must protect each deposit individually within 30 days of receiving it and provide prescribed information to each tenant.

If multiple tenants share a joint tenancy and pay a single combined deposit, you protect that total amount as one deposit and provide prescribed information to all tenants named on the tenancy agreement.

For rooms in an HMO where tenants come and go on rolling contracts, track deposit protection carefully. When one tenant leaves and a new one arrives, if there's a new deposit, it must be protected within 30 days of receipt.

Record Keeping

Keep comprehensive records of deposit protection for every tenancy. Store proof of protection, prescribed information provided to tenants, proof of delivery of prescribed information, and deposit return records or adjudication decisions.

Retain these records for at least six years after the tenancy ends. This aligns with general landlord record-keeping requirements and tax record retention periods.

If you use a digital system to track documents, include deposit protection records. Search by property, tenant, or date. Export evidence if needed for tribunal or court.

The Bottom Line

Deposit protection compliance is non-negotiable. You must protect every deposit in an approved scheme within 30 days of receiving it. You must provide prescribed information to tenants within the same 30-day window. And critically, you must prove you did both.

The penalties for failure are severe: one to three times the deposit amount paid to the tenant, plus inability to regain possession under multiple grounds. These penalties apply even if the failure was accidental or you later corrected it.

Set up a system that automatically protects deposits when received. Use calendar reminders if needed. Track the 30-day deadline from the date you received the money, not from the tenancy start date. Send prescribed information using methods that create proof: tracked emails, digital platforms with access logs, or registered post with signature confirmation.

Our comprehensive landlord compliance checklist includes deposit protection alongside all other mandatory requirements.

Deposit protection has been the law for nearly 20 years. Courts have no sympathy for landlords who fail to comply. Get it right every time, create proof of compliance, and avoid entirely preventable penalties.
