What Happens If a Landlord Doesn't Protect a Deposit

Deposit protection is one of the most fundamental legal requirements for landlords in England and Wales. Getting it wrong — whether by failing to protect the deposit entirely, missing the 30-day deadline, or not providing the prescribed information — carries serious consequences. Here's what every landlord needs to know.

The Legal Requirement

Under the Housing Act 2004 (as amended), if you take a deposit from a tenant on an assured shorthold tenancy (AST) in England or Wales, you must protect it in one of three government-approved tenancy deposit schemes within 30 days of receiving it. You must also provide the tenant with prescribed information about the protection within the same 30-day period.

Since the Renters' Rights Act 2025 converted all ASTs to periodic tenancies, these requirements continue to apply. The obligation does not go away just because the tenancy structure has changed.

The Three Approved Schemes

There are three government-authorised deposit protection schemes in England. Each offers both a custodial (free) and insured (paid) option:

Deposit Protection Service (DPS)

The DPS is the largest scheme. In the custodial option, the deposit is held by the DPS itself. In the insured option, the landlord retains the deposit but pays a fee to insure it. The DPS provides a free dispute resolution service.

MyDeposits

MyDeposits offers both custodial and insured options. It is part of the Hamilton Fraser group and provides an online portal for managing deposit protection, along with a free alternative dispute resolution (ADR) service.

Tenancy Deposit Scheme (TDS)

The TDS also provides custodial and insured options. Like the other two schemes, it offers a free dispute resolution service for end-of-tenancy deposit disputes.

All three schemes are equally valid. The choice between them is yours, though you should consider the quality of their online platform, dispute resolution track record, and any fees for the insured option.

The 30-Day Deadline

You have precisely 30 calendar days from the date you receive the deposit to both protect it in an approved scheme and serve the prescribed information on the tenant. This deadline is strict and courts have consistently refused to accept excuses for missing it.

The 30-day clock starts from the day the deposit is received — not the day the tenancy starts. If a tenant pays the deposit two weeks before move-in, the 30 days run from the payment date.

For detailed guidance on meeting this deadline, see our guide on deposit protection within 30 days.

Prescribed Information

Protecting the deposit in a scheme is only half the obligation. You must also serve the tenant with prescribed information within the same 30-day window. The prescribed information includes:

• The name, address, and contact details of the deposit protection scheme
• The landlord's name, address, and contact details (or the agent's, if applicable)
• The tenant's name and the address of the rented property
• The amount of the deposit
• How the deposit is protected (custodial or insured)
• Information about the scheme's dispute resolution procedure
• The circumstances in which all or part of the deposit may be retained
• What the tenant should do if they cannot get a response from the landlord at the end of the tenancy

Each deposit protection scheme provides a template prescribed information document. Use it — the templates are designed to comply with the regulations and omitting required information can be treated the same as not serving it at all.

You must also serve a copy of the government's "How to Rent" guide at the outset of the tenancy, though this is a separate requirement.

Consequences of Failing to Protect a Deposit

The penalties for non-compliance with deposit protection requirements are severe and well-established in case law.

Financial Penalty: 1 to 3 Times the Deposit Amount

If a tenant applies to the county court and proves that the deposit was not protected within 30 days or that the prescribed information was not served, the court must order the landlord to pay compensation of between one and three times the deposit amount. This is not discretionary — the court is required to award at least 1x the deposit.

For example, if the deposit is £1,200, the penalty could be between £1,200 and £3,600 — on top of returning the deposit itself. The court determines the multiplier based on the circumstances, including how long the breach lasted and whether it was deliberate.

Inability to Serve Section 21 Notice (Legacy Tenancies)

Under the pre-Renters' Rights Act regime, landlords could not serve a valid Section 21 notice while the deposit remained unprotected or prescribed information had not been served. Although Section 21 has been abolished by the Renters' Rights Act 2025, this remains relevant for any legacy proceedings that began before the Act came into force.

Impact on Section 8 Proceedings

Under the current framework, deposit protection failures can complicate Section 8 possession proceedings. While a failure to protect a deposit does not technically prevent you from serving a Section 8 notice, it gives the tenant a powerful counterclaim. A tenant facing eviction for rent arrears may apply for the deposit penalty, offsetting or exceeding the arrears owed.

This means that in practice, unprotected deposits can make it significantly harder to recover possession, even where the tenant is genuinely in arrears.

Ongoing Liability

The penalty for non-protection is not a one-off risk. A tenant can bring a claim at any time during the tenancy or after it ends, as long as the deposit has not been properly protected. Some courts have held that the liability persists for up to six years after the tenancy ends under the Limitation Act 1980.

Common Mistakes Landlords Make

Many deposit protection failures are not deliberate. Common errors include:

• Missing the 30-day deadline: The landlord intends to protect the deposit but simply does not get around to it in time
• Protecting but not serving prescribed information: The deposit is placed in a scheme, but the tenant never receives the required documentation
• Not re-protecting after a tenancy renewal: In some circumstances, a new fixed-term agreement may require fresh protection and prescribed information. While this has been simplified under periodic tenancies, check your scheme's requirements
• Using the wrong scheme: Occasionally, a landlord or agent uses a scheme that is not one of the three government-approved schemes, which does not count as valid protection
• Protecting the wrong amount: If the deposit amount registered with the scheme does not match the amount actually taken, this may be treated as non-compliance
• Not updating after a rent change: If the deposit amount changes (rare but possible), the protection details may need updating

How to Fix Late Protection

If you realise that you have not protected a deposit within the 30-day deadline, act immediately. While late protection does not retrospectively cure the breach, it can limit the damage:

1. Protect the deposit now: Register it with one of the three approved schemes as soon as possible
2. Serve the prescribed information: Provide the tenant with all required documentation immediately
3. Keep proof of both actions: Save confirmation emails, certificates, and records of when and how you served the prescribed information on the tenant
4. Consider the risk: Understand that the tenant may still have a claim for the period the deposit was unprotected. If the relationship is good, the tenant may never pursue it — but you cannot rely on this

Courts have generally shown more leniency (awarding 1x rather than 3x the deposit) where the landlord took steps to protect the deposit as soon as the error was discovered, compared to landlords who knew about the requirement and deliberately ignored it.

The Tenant Claims Process

If a tenant believes their deposit has not been properly protected, they can take the following steps:

1. Check the schemes: The tenant can check with all three approved schemes (DPS, MyDeposits, TDS) to see whether their deposit is registered. This can usually be done online.
2. Write to the landlord: The tenant will typically write to the landlord asking for evidence of deposit protection and prescribed information. This letter may come from the tenant directly or from a solicitor.
3. Apply to the county court: If the landlord cannot demonstrate compliance, the tenant can issue a claim in the county court under Section 214 of the Housing Act 2004.
4. Court hearing: At the hearing, the burden is on the landlord to prove that the deposit was protected and prescribed information was served within the 30-day deadline.
5. Judgment: If the court finds that the landlord failed to comply, it must order the deposit to be returned (or protected if the tenancy is ongoing) and award the 1–3x penalty.

Tenants can also raise deposit protection failures during tribunal proceedings as a counterclaim, which makes proper protection doubly important if you ever need to take action against a tenant.

Deposit Protection and the Renters' Rights Act 2025

The Renters' Rights Act has not changed the fundamental deposit protection requirements, but it has altered the context in several important ways:

• All tenancies are now periodic: There is no need to worry about re-protection when a fixed term expires and becomes periodic, as all tenancies are periodic from the outset
• No Section 21: With Section 21 abolished, the inability to serve a Section 21 notice for unprotected deposits is no longer the main concern — but the financial penalties remain
• Stronger enforcement: The new ombudsman and stronger local authority powers mean tenants have more routes to report non-compliance. See our guide on the Renters' Rights Act and what landlords must do
• The deposit cap remains: Deposits are still capped at five weeks' rent where the annual rent is below £50,000

Best Practices for Deposit Protection

• Protect the deposit on the day you receive it — do not wait. The 30-day window is a maximum, not a target
• Serve prescribed information immediately and keep proof of delivery (email read receipts, recorded post, or a system that logs delivery with a timestamp)
• Keep a copy of the deposit protection certificate and the prescribed information in your property file
• Set a reminder to check that protection is active and has not lapsed, especially if using the insured option which may require annual renewal
• At tenancy end, follow the scheme's process for returning or disputing the deposit. Do not withhold the deposit outside the scheme's procedures

Deposit protection is one of the items on the landlord compliance checklist — ensure it is not missed among the many other obligations at tenancy start.

Key Takeaways

• You must protect the deposit in an approved scheme (DPS, MyDeposits, or TDS) and serve prescribed information within 30 days
• Failure to comply results in a mandatory penalty of 1–3x the deposit amount if the tenant brings a court claim
• Unprotected deposits can complicate or undermine Section 8 possession proceedings
• If you have missed the deadline, protect the deposit immediately and serve the prescribed information — late action can reduce the penalty multiplier
• Keep proof of protection and delivery of prescribed information for the duration of the tenancy and beyond
• The Renters' Rights Act 2025 has not removed deposit protection requirements — they remain fully in force
