Tenancy Deposit Protection UK 2026: Complete Guide

Every residential tenancy deposit taken in England must be protected in a government-approved Tenancy Deposit Protection (TDP) scheme within 30 days of receipt, and the tenant must receive the prescribed information within the same window. These are hard legal deadlines under the Housing Act 2004. Miss either one and you face a court-ordered fine of up to three times the deposit amount — and lose your right to serve a valid Section 21 notice until you remedy the breach.

This guide covers every aspect of deposit protection: how much you can legally charge, which of the three approved schemes to use, the custodial vs insured choice, exactly what the prescribed information must include, how to handle deductions at the end of a tenancy, and what the adjudication process looks like when there is a dispute.

How Much Deposit Can You Legally Take?

The Tenant Fees Act 2019, which applies to all tenancies in England since 1 June 2019, caps the security deposit at:

• 5 weeks’ rent where the annual rent is less than £50,000
• 6 weeks’ rent where the annual rent is £50,000 or more

The calculation uses the rent at the time the deposit is taken. A tenancy at £1,200 per month (£14,400 per year) has a maximum deposit of £1,384.62 (£14,400 ÷ 52 × 5). If you take more than the permitted amount, the excess is an unlawfully charged prohibited payment — you must return it, and a breach carries a fine of up to £5,000 per incident.

The Act also caps holding deposits (paid when a tenant reserves a property before signing) at one week’s rent. A holding deposit must be repaid or credited against the first month’s rent or the security deposit once the tenancy starts. See our first-time landlord checklist for all pre-tenancy compliance steps alongside deposit rules.

Wales operates under the Renting Homes (Fees etc.) (Wales) Act 2019 with equivalent caps. Scotland has its own deposit protection framework under the Housing (Scotland) Act 2006 — the approved schemes and the 30-working-day deadline differ from England’s rules.

The 30-Day Deadline: What Must Happen and When

Under the Housing Act 2004 s.213(3), as amended by the Localism Act 2011 s.184, you have 30 calendar days from the date the deposit is received to:

1. Register the deposit with a government-approved TDP scheme
2. Obtain the deposit protection certificate or scheme reference number
3. Serve the prescribed information on the tenant and any relevant person who paid the deposit (such as a parent guarantor or third-party payer)

The clock starts the moment the money clears into your account — not on the tenancy start date. If a tenant pays a deposit two weeks before the move-in date, your 30-day window begins immediately.

The 30-day rule applies again when:

• You take a deposit top-up after a rent increase and want to uplift the protected amount
• You re-protect a deposit at the start of a new fixed term with the same tenant in a new agreement
• You become a landlord through purchase of a tenanted property and the existing deposit was never protected

What does not restart the clock: A fixed-term tenancy rolling into a statutory periodic tenancy does not require re-protection, provided the deposit was validly protected before the conversion. Under the Renters’ Rights Act 2025, which converts all ASTs to periodic tenancies, an existing valid protection carries over automatically.

The Three Government-Approved TDP Schemes

The Housing Act 2004 authorises three schemes for England and Wales. All three are independent, regulated, and obliged to provide a free Alternative Dispute Resolution (ADR) service for deposit disputes.

Deposit Protection Service (DPS)

DPS is the largest scheme by volume and offers both custodial and insured products. The DPS Custodial scheme is entirely free — the scheme holds deposits on behalf of landlords with no annual membership fee. The DPS Insured product charges a per-deposit fee and allows the landlord to retain the funds in their own account.

The DPS online portal is straightforward to use and its adjudication service runs structured 28-day evidence windows. It is the most common choice for self-managing landlords.

MyDeposits

MyDeposits operates an insured scheme and a custodial option. It is widely used by letting agents and national agent networks. Landlord registration is available directly. MyDeposits provides detailed guidance notes for adjudication that are useful reading even if you are not using the scheme.

Tenancy Deposit Scheme (TDS)

TDS offers both TDS Custodial (free) and TDS Insured (fee-based). TDS publishes annual dispute data and detailed adjudication guidance — its website is the most useful public resource for understanding what evidence adjudicators actually consider when deciding contested deductions.

Any of the three schemes is a valid choice. What matters is that you use whichever scheme you choose consistently — do not split deposits across schemes without good reason, as it complicates end-of-tenancy administration.

Custodial vs Insured: Which to Choose?

	Custodial	Insured
Who holds the money	The scheme	You (landlord or agent)
Annual fee	Free	Per-deposit fee
Best for	Self-managing landlords	Agents managing portfolios
Dispute outcome	Scheme releases directly	You must repay scheme if you lose
Risk to landlord	None	Must have funds available to repay
Interest on deposit	Retained by scheme	You can earn interest

For a landlord with one to ten properties, custodial is almost always the right choice. There is no fee, the money is ringfenced and cannot be confused with your own funds, and you do not need to find the deposit amount quickly if adjudication rules against you. The only practical downside is that the money sits outside your current account — relevant only if you rely on tenant deposits for cashflow, which creates significant legal and financial risk.

Insured schemes make sense for letting agents managing dozens of tenancies simultaneously, where maintaining liquidity across all deposits in a custodial framework is impractical.

Prescribed Information: The Document You Must Serve Within 30 Days

The prescribed information is a legally mandated document under the Housing (Tenancy Deposits) (Prescribed Information) Order 2007. It must be served within the same 30-day window as the protection itself — it is a separate obligation, not an optional supplement.

The prescribed information must contain all of the following:

• The deposit amount and the date it was protected
• The address of the tenanted property
• Your name and contact details (or the agent’s, if applicable)
• The tenant’s name and contact details
• The name and contact details of any relevant person who paid the deposit
• The full name and contact address of the TDP scheme
• The name and contact address of the scheme’s ADR service
• How to apply to have the deposit returned at the end of the tenancy
• What happens if the landlord or tenant cannot be contacted at the end of the tenancy
• The scheme’s terms and conditions (or a reference to where they can be found)

Every TDP scheme provides a standard prescribed information template that meets the Order’s requirements — download it from the scheme website and complete it fresh for each tenancy.

Serve it in writing with proof of receipt. Email with read receipt or delivery confirmation is sufficient. If the tenant later denies receiving it, you need dated evidence. Keep a signed copy on file. If there is a relevant person (for example, a parent who paid the deposit on behalf of a student), they must receive the prescribed information separately.

Serving the prescribed information late — even by one day — triggers the same 1–3× penalty regime as failing to protect the deposit at all.

Returning the Deposit at the End of a Tenancy

When the tenancy ends, the deposit must be returned to the tenant (net of any agreed deductions) within 10 working days of both parties reaching agreement on the split.

The practical sequence for a clean checkout:

1. Conduct the check-out inspection with the tenant present, or use a professional inventory clerk
2. Compare the check-out report against the original check-in inventory item by item
3. Agree deductions in writing — by email or through the scheme’s online portal
4. Submit a repayment request to the TDP scheme specifying the exact amount to each party
5. The scheme releases the funds within 10 working days of the agreed instruction

If you cannot agree on deductions, either party can refer the matter to the scheme’s ADR service. The scheme then freezes the disputed portion pending adjudication. The undisputed portion — rent, undamaged deposit amount — must be returned promptly regardless of the ongoing dispute. Withholding the undisputed portion is a separate breach.

Permitted Deductions: What the Rules Allow

Deductions are lawful only for specific purposes:

Allowed:

• Unpaid rent outstanding at the end of the tenancy
• Damage beyond fair wear and tear — broken fixtures, stained carpets, holes in walls, burn marks
• Professional cleaning where the property is returned in materially worse condition than documented at check-in
• Missing inventory items listed on the check-in report that are absent at check-out
• Unpaid utility bills where your tenancy agreement makes the tenant liable

Not allowed:

• Normal wear and tear — fading paintwork, minor scuffs on walls, light carpet flattening in high-traffic areas
• Maintenance defects that were your legal responsibility under Section 11 of the Landlord and Tenant Act 1985 (structural repairs, heating, plumbing, sanitation)
• Cosmetic improvements you choose to make between tenancies
• Anything not supported by a comparison between the check-in and check-out reports

The strength of your evidence determines adjudication outcomes. A signed, dated, photographic check-in inventory is the single most important document for any contested deposit claim. Adjudicators will not accept undated photographs, verbal descriptions, or deduction estimates without supporting professional cleaning quotes or repair invoices. If the property was let to a tenant with a pet, document pet-specific damage separately — scratch marks, fouled carpets, and flea treatment costs are all claimable where evidenced. See the landlord pet rules guide for how to structure pet damage protection from the start of the tenancy.

Deposit Dispute Adjudication: How It Works

If the tenant challenges any proposed deduction, either party can trigger the scheme’s ADR process. The Housing Act 2004 requires all TDP schemes to operate ADR and prohibits tenancy agreement clauses that waive a tenant’s right to use it.

The process:

1. Either party submits a dispute form to the scheme online
2. The scheme notifies both parties and sets evidence submission deadlines — typically 28 days for each side
3. You submit your evidence: signed check-in inventory, dated photographs, check-out report, professional cleaning invoice, repair quotes or completion invoices
4. The tenant submits their counter-evidence
5. An independent adjudicator decides — usually within 28 days of closing the evidence window
6. The scheme releases funds according to the adjudicator’s decision

The ADR service is entirely free to both parties. Adjudicator decisions can be challenged in county court under the Housing Act 2004 s.214, but this is uncommon. In the majority of cases, the evidence quality determines the outcome: thorough inventory documentation supported by dated photographs almost always outperforms verbal assertion.

If the tenant refuses to engage with ADR — which is unusual — you can apply to county court directly for a determination.

Penalties for Non-Compliance: The Full Picture

The Housing Act 2004 creates two separate obligations: protecting the deposit and serving the prescribed information. Breaching either one exposes you to the same penalty regime under s.214.

Penalties on a successful tenant application:

• A court order requiring you to repay the deposit (or pay an equivalent sum into court)
• A fine of between 1 and 3 times the deposit amount — the court determines the multiplier
• Inability to serve a valid Section 21 notice while any breach remains unremedied

The court’s choice of multiplier reflects the seriousness of the breach. A deliberate, prolonged failure to protect a deposit at all is more likely to attract the maximum 3× penalty. An inadvertent short delay with evidence of prompt remedy may attract only 1×. Even a 1× award on a £1,500 deposit costs you £1,500 on top of returning the full deposit.

A tenant has up to 6 years to bring a claim for TDP non-compliance under the Limitation Act 1980. This means tenancies that ended several years ago can still generate liability if the deposit was never validly protected.

To serve a valid Section 21 notice, the deposit must be protected and the prescribed information must have been served. If you have not met both requirements, you must either return the deposit in full first or remediate the breach before issuing. The how to evict a tenant guide covers the full eviction process and where deposit compliance fits within it.

Tenancy Deposit Protection and the Renters’ Rights Act

The Renters’ Rights Act 2025 — in force from May 2026 — abolishes Section 21 no-fault evictions and converts all fixed-term ASTs to periodic tenancies. The core TDP obligations are unchanged: deposits must still be protected within 30 days, prescribed information must still be served, and the 1–3× penalty for non-compliance remains in force.

The practical shift is that the Section 21 sanction for TDP non-compliance loses its force once Section 21 is unavailable to all landlords. However, proper deposit management remains essential for Section 8-based evictions: a dispute over deductions that turns adversarial is frequently the catalyst for a tenant to raise counterclaims — extending any possession proceedings and increasing costs significantly.

The Renters’ Rights Act guide covers the full legislative changes and how they affect possession, rent increases, and tenancy structure in 2026.
