Deposit Protection Scheme Rules UK: What Landlords Must Know

You must protect an assured shorthold tenancy deposit within 30 calendar days of receiving it. The deposit belongs in one of three government-approved deposit protection schemes (DPS) until the tenancy ends. You must also give the tenant prescribed information about the scheme within the same 30-day window, or you cannot serve a valid Section 21 notice.

Breaking these rules triggers an automatic penalty: the tenant can take you to court and claim between one and three times the deposit value. This guide explains the deposit protection scheme rules every UK landlord must follow, including deadlines, scheme types, prescribed information requirements, and what happens when you get it wrong.

What Counts as a Deposit Under UK Law

A tenancy deposit is any money a tenant pays to cover potential damage, unpaid rent, or cleaning costs at the end of the tenancy. The law calls it a 'security deposit' — it's different from rent or a holding deposit. Most landlords take one month's rent as the deposit, but there's no legal cap on the amount for assured shorthold tenancies (ASTs) that started before 1 June 2019.

From 1 June 2019, the Tenant Fees Act 2019 caps deposits at five weeks' rent if the annual rent is under £50,000, or six weeks' rent if it's £50,000 or more. This applies to new tenancies and renewals signed after that date. If you took a larger deposit before June 2019 and the tenant stays on a statutory periodic tenancy (rolling month-to-month after the fixed term ends), the old deposit amount is protected under the old rules — you don't need to refund the excess unless you agree a new tenancy.

Holding deposits are different: a tenant pays this to reserve the property while referencing happens. Under the Tenant Fees Act, a holding deposit is capped at one week's rent. Once the tenant moves in, you must either return the holding deposit or count it towards the first month's rent or the main tenancy deposit. Holding deposits don't need protecting in a deposit protection scheme, but you must handle them according to strict rules and return them within seven days if the tenancy doesn't go ahead (unless the tenant provides false information or withdraws).

The Three Government-Approved Deposit Protection Schemes

You must use one of three schemes approved under the Housing Act 2004. Each scheme is free to join. You choose between custodial (the scheme holds the money) or insurance-backed (you hold the money but pay for insurance). The schemes are:

• Tenancy Deposit Scheme (TDS): Offers both custodial and insured options. You register the deposit online, and TDS provides free dispute resolution if you and the tenant disagree on deductions at the end.
• MyDeposits: Run by Tenancy Deposit Solutions Ltd, also offering custodial and insured routes. They hold over £1 billion in deposits and handle disputes through an independent adjudication service.
• Deposit Protection Service (DPS): The largest scheme by volume, managing millions of deposits. Custodial is free; insured has an annual membership fee.

You can switch schemes between tenancies, but you cannot move a deposit from custodial to insured (or vice versa) mid-tenancy without the tenant's agreement. If you use the custodial route, you transfer the deposit to the scheme within 30 days and they hold it in a separate bank account. At the end of the tenancy, both parties propose how to split the deposit; if you agree, the scheme releases the money. If you disagree, the scheme's free alternative dispute resolution (ADR) service makes a binding decision.

With the insured route, you keep the deposit in your own account (ideally a separate client account, though not legally required). You pay a small fee per deposit for insurance. If a dispute arises and you lose, the scheme pays the tenant from the insurance pot and then recovers the money from you. This option suits landlords who want to keep the deposit earning interest or who have cash flow reasons to hold the funds, but you must repay any disputed amount you lose.

The 30-Day Deadline and Prescribed Information

You have 30 calendar days from the date you receive the deposit to protect it and serve prescribed information on the tenant. The countdown starts the day the money enters your account — not the tenancy start date. If the tenant pays the deposit two weeks before moving in, your 30 days start then. Miss this deadline and you're in breach, even if you protect the deposit on day 31.

Prescribed information is a specific list of details the government requires you to give the tenant in writing. The content is set out in the Housing (Tenancy Deposits) (Prescribed Information) Order 2007 (as amended). It includes:

• The deposit amount and the date you received it
• The address of the rental property
• The name and contact details of the scheme holding the deposit
• Your (the landlord's) name, address, contact details, and those of any agent
• The tenant's name and contact details
• How to apply to get the deposit back at the end of the tenancy
• What to do if there's a dispute about deductions
• A statement confirming that if the tenant doesn't request the return of the deposit at the end of the tenancy, you can apply to the scheme to release it
• If it's an insured scheme, confirmation that the deposit is protected and details of the insurance arrangement

Each deposit protection scheme provides a template prescribed information document. You can use that template or write your own, but you must include every required detail. Send it by email, post, or hand-delivery — just make sure you can prove the tenant received it. An email read receipt or signed acknowledgment is helpful if a dispute arises later.

If you protect the deposit but forget to serve prescribed information within 30 days, you're still in breach. The law treats both steps as equally important. Some landlords mistakenly think protecting the money is enough — it isn't. You need both.

What Happens If You Break the Rules

Failing to protect a deposit or serve prescribed information within 30 days has three immediate consequences. First, you cannot serve a valid Section 21 notice to end the tenancy until you fix the breach. Even if you protect the deposit late, you must wait until the breach is 'cured' before serving Section 21. Courts will throw out any Section 21 notice issued while the deposit was unprotected or prescribed information was missing.

Second, the tenant can take you to court and claim a penalty of between one and three times the deposit amount. The court decides the multiple based on how serious your breach was, but even an honest mistake typically results in at least one times the deposit. If you deliberately ignored the rules or refused to protect the deposit after being asked, expect the full three times penalty. This is a civil claim in the county court — the tenant doesn't need to prove financial loss, just that you broke the rules.

Third, if you eventually want to make deductions from the deposit for damage or unpaid rent, your case is weaker if you didn't protect it properly. Deposit protection schemes and courts expect landlords to follow the rules. If you didn't, the adjudicator or judge may be less sympathetic to your deduction claims, even if the damage is genuine. You also lose access to the free dispute resolution service if you never protected the deposit in a scheme.

There's no time limit on when a tenant can bring a claim for failing to protect a deposit. Even after the tenancy ends, they have six years from the date of the breach to sue you. If you never protected the deposit during a three-year tenancy, the tenant could wait until after they move out and still claim the penalty.

Fixed-Term, Periodic, and Renewal Tenancies

The deposit protection rules apply from the start of an assured shorthold tenancy and continue until the tenancy ends. If a fixed-term AST becomes a statutory periodic tenancy (rolling month-to-month with no new agreement), the deposit stays protected under the original scheme — you don't need to re-protect it or serve new prescribed information. The law treats it as the same tenancy.

If you and the tenant sign a new fixed-term agreement (a renewal), you technically create a new tenancy. Strictly speaking, you should re-protect the deposit and serve fresh prescribed information, even if you're using the same scheme. In practice, many landlords keep the deposit in the same scheme and just issue updated prescribed information with the new tenancy dates. The safest approach is to confirm with your chosen scheme how they handle renewals — some schemes allow you to log a renewal within the existing protection; others recommend starting fresh.

If the tenant pays a top-up to the deposit during the tenancy (for example, to cover a rent increase or additional damage risk), you must protect the new total within 30 days and serve updated prescribed information. The top-up is treated as a new deposit payment, and the 30-day clock starts again for that additional amount.

When You Don't Need to Protect a Deposit

Deposit protection rules only apply to assured shorthold tenancies in England and Wales. If the tenancy is an assured tenancy (without the 'shorthold' element), or an excluded tenancy such as a lodger living in the same property as the landlord, you don't legally need to protect the deposit. However, it's still good practice to hold it in a separate account and document the agreement in writing.

Company lets (where the tenant is a limited company, not an individual) are usually excluded from deposit protection rules if the company rents the property for employees. Check the specific circumstances — if the occupier has exclusive possession and pays rent as an individual, it might still be an AST. If in doubt, protect the deposit anyway; it costs nothing for custodial schemes and provides dispute resolution.

Student accommodation provided by universities or colleges as part of the course is often exempt, as are some social housing tenancies managed by councils or housing associations under different rules. Deposits for commercial leases (shops, offices) have no protection requirements; they're governed by the commercial lease terms.

In Scotland, landlords must use a government-approved scheme under separate Scottish legislation (Tenancy Deposit Schemes (Scotland) Regulations 2011). The deadline is 30 working days, and the approved schemes are different from England and Wales. In Northern Ireland, there's a separate Tenancy Deposit Scheme run by the Department for Communities, but the protection requirement didn't start until April 2013. Always check the current law for the relevant country.

Deductions, Disputes, and Returning the Deposit

When the tenancy ends, you and the tenant agree how to split the deposit. If you want to deduct money for damage beyond normal wear and tear, unpaid rent, or missing items, you must provide evidence: photos, receipts, invoices, an inventory, and a check-in/check-out report. The deposit scheme expects you to justify every deduction. Normal wear and tear (faded paint, worn carpet in high-traffic areas, minor scuffs) is not deductible — only damage caused by the tenant's action or negligence counts.

If you both agree, the scheme releases the money according to your agreement — usually within a few days. If you disagree, either party can start the dispute resolution process. This is free and typically faster than going to court. You each submit evidence online or by post, and an independent adjudicator reviews the case and makes a binding decision. The adjudicator's decision is final for that deposit; you can't then go to court over the same issue unless there was a procedural error.

For custodial schemes, the disputed amount stays with the scheme until the adjudicator decides. For insured schemes, you must hand over the disputed amount to the scheme within 10 days of the tenant rejecting your proposed deductions. If you don't, the scheme can claim from the insurance and you lose the dispute by default. This rule prevents landlords from holding onto money during a dispute.

You must return the tenant's share of the deposit (or confirm deductions) within 10 days of the end of the tenancy if you both agree on the amount. If there's no agreement, you should still start the dispute process promptly. Delaying without reason damages your case and can result in the adjudicator awarding the full deposit to the tenant.

Record-Keeping and Evidence

Good record-keeping protects you in disputes. Take time-stamped photos of every room and fixture on the day the tenant moves in, and again when they move out. Use a professional inventory clerk if possible, or at least a detailed written inventory both parties sign. Note the condition of walls, floors, appliances, carpets, and any existing damage. If something is already worn or marked, record it — otherwise you can't deduct for it later.

Keep copies of all emails and letters about the deposit: the protection certificate from the scheme, the prescribed information you served, any correspondence about deductions, and receipts for repairs. If you hire a cleaner or contractor to fix damage, get a proper invoice with a breakdown of work done. 'Reasonable' deductions must be backed by evidence of actual cost — you can't charge the tenant more than you paid to fix something.

If the tenant reports maintenance issues during the tenancy (for example, leaks that could cause damp), document how you responded. If they later claim you caused damage by failing to repair, your records prove you acted. This is particularly relevant for issues like damp and mould, where the landlord's failure to fix a problem can lead to deductions being denied or even a counter-claim from the tenant.

Common Mistakes and How to Avoid Them

Many landlords protect the deposit but serve prescribed information late, or forget to send it at all. Set a reminder for day 28 after receiving the deposit to check both tasks are complete. If you use a letting agent, confirm in writing that they will handle deposit protection and prescribed information on your behalf — and get proof they've done it. If the agent fails, you as the landlord are still liable for the penalty.

Another mistake is protecting only part of the deposit. If a tenant pays £1,200 as a deposit, you must protect all £1,200, not just the first month's equivalent. Some landlords think they can hold back a portion for immediate repairs or use it as a buffer; you can't. Protect the full amount within 30 days, then sort out any agreed deductions at the end of the tenancy.

Landlords sometimes assume that because the tenancy agreement mentions deposit protection, the job is done. It isn't. You must actually register the deposit with a scheme and serve the prescribed information document. The tenancy agreement clause is not a substitute for compliance.

If you're late protecting a deposit, act immediately. Protect it as soon as you realise the mistake, serve prescribed information, and write to the tenant apologising and confirming the deposit is now protected. This won't erase the breach, but it reduces the penalty risk if the tenant takes you to court. Some tenants will accept the apology and move on; others will claim the penalty. You cannot serve a Section 21 notice until you've corrected the breach, and even then, some lawyers argue you must wait a reasonable period after correction before Section 21 becomes valid.

Changes to Deposit Rules and Section 21

The government has announced plans to abolish Section 21 'no-fault' evictions under the Renters (Reform) Bill. Once the law changes, landlords will no longer be able to use Section 21 to end a tenancy without providing a reason. Instead, you'll need to rely on Section 8 grounds (such as rent arrears, anti-social behaviour, or selling the property). Deposit protection rules will still apply, but the link between deposit protection compliance and Section 21 validity will become less critical — though the financial penalties for failing to protect a deposit will remain.

The Tenant Fees Act 2019 tightened deposit caps and banned most other charges to tenants. If you take a prohibited payment (such as a tenancy renewal fee or a charge for providing a reference), you can face a £5,000 fine and the tenant can reclaim the money. Always check that any fee you charge is allowed under the Act. Permitted payments include rent, deposits (up to the five or six weeks cap), holding deposits (up to one week's rent), and payments for replacing lost keys or late rent (if specified in the tenancy agreement).

Some local authorities have introduced selective licensing schemes that require landlords to hold a licence to rent out properties in certain areas. Licence conditions often include deposit protection compliance as a standard requirement. Breaching your licence conditions can result in prosecution, unlimited fines, and a rent repayment order forcing you to refund up to 12 months' rent to the tenant. Check your council's website to see if your property falls under a licensing scheme.
