TL;DR

Tenancy deposit protection London landlords must arrange covers every deposit taken on every assured tenancy — there is no minimum threshold, no exemption for short tenancies, and no exemption for trusted tenants. Three government-approved schemes operate (TDS, DPS, mydeposits) across custodial and insurance-based models. The deposit must be protected within 30 days of receipt and prescribed information given to the tenant. Failure carries up to three times the deposit as a penalty plus inability to recover possession.

The Renters’ Rights Act 2025, which commenced on 1 May 2026, kept the deposit protection framework substantially unchanged but significantly expanded the surrounding enforcement regime — Rent Repayment Orders now extend up to two years of rent and apply for two years from the offence. This guide explains the statutory framework, scheme choice, deduction process, and how the post-RRA regime affects deposit handling.

What tenancy deposit protection actually means

Tenancy deposit protection London law has required since the Housing Act 2004 commenced in April 2007. Before that, landlords held deposits in their own bank accounts and disputes were resolved through county court claims that took months and often delivered inadequate remedies. The 2007 regime created three government-approved schemes that hold the money (or insure it), with statutory adjudication for end-of-tenancy disputes.

The protection framework has two parts. First, the landlord must protect the deposit money in one of three government-approved schemes within 30 days of receipt. The schemes are operated by independent bodies under contract with government. Second, the landlord must give the tenant prescribed information — the scheme name and contact details, the deposit amount, the property address, and how the tenant can recover the deposit at the end of the tenancy — within the same 30-day window.

Failure to comply with either requirement triggers significant consequences. The tenant can apply to court for compensation of between one and three times the deposit amount. The landlord cannot serve a possession notice (previously Section 21, now the equivalent under the new regime) for any non-compliant tenancy. These penalties are not theoretical — they are routinely awarded in county court.

Tenancy deposit protection London law applies to every assured tenancy (and now every periodic tenancy under the Renters’ Rights Act regime). There is no threshold deposit amount that triggers protection; a £100 deposit must be protected just as a £5,000 deposit must be protected. There is no exemption for short tenancies, family tenants, or known tenants from prior tenancies. The only exemptions sit at the margins of housing law — non-assured arrangements like lodger agreements where the landlord lives in the property, or commercial lets.

The three approved schemes

Tenancy deposit protection London landlords use is administered by three government-approved schemes. Each scheme offers a custodial option (the scheme holds the money) and an insurance-based option (the landlord holds the money and pays an insurance premium to the scheme). Each scheme has its own application process, fee structure, and dispute resolution workflow.

Tenancy Deposit Scheme (TDS) — the longest-established of the three, with extensive case law informing its adjudication approach. TDS operates both custodial and insurance-based schemes. The custodial option is free for landlords; the insurance-based option charges a per-tenancy fee. TDS adjudicators are widely viewed as the most experienced in the sector.

Deposit Protection Service (DPS) — operated by Computershare under government contract. The DPS custodial option is the most widely used scheme in the UK; the insurance-based “Insured” option exists but is less prominent. DPS is free at point of use for the custodial option, with interest on deposits going to fund the service.

mydeposits — operated by the National Approved Letting Scheme (NALS). Offers both custodial and insurance-based options. Active marketing toward independent landlords and small portfolio holders. Some scheme features (early release options, specific dispute workflows) differ in detail from TDS and DPS.

A future spoke (S4.3) will compare the three schemes head-to-head on fees, workflows, adjudication outcomes, and operational fit for different landlord profiles. For now: most landlords pick DPS custodial for simplicity (free, scheme holds the money) or TDS Insured for portfolio scale (landlord holds the money, scheme provides dispute resolution).

The choice of scheme should be made before any deposit is taken — switching schemes mid-tenancy requires careful handling to avoid breaking the 30-day protection chain. A landlord with multiple properties should normally use the same scheme across the portfolio for operational simplicity.

How to protect a deposit correctly — the 30-day rule

The 30-day rule is the single most common compliance failure in tenancy deposit protection London landlords encounter. The countdown begins on the day the deposit is received from the tenant (or their agent on their behalf), not on the day the tenancy starts. A deposit received on a Monday must be protected by Tuesday of week five at the latest.

The protection itself requires four operational steps:

Step one — choose the scheme. Decide before the tenant pays. Most landlords pick custodial for simplicity, but if the landlord runs a managed portfolio with treasury operations, insurance-based may make more sense. The scheme should be chosen across the portfolio rather than per-property.

Step two — register the deposit. For custodial schemes, this means transferring the money to the scheme’s bank account and submitting the registration form online. For insurance-based schemes, it means paying the insurance premium and submitting the registration. Either way, the registration must be complete within 30 days.

Step three — provide prescribed information to the tenant. This is a specific list of details that must be given to the tenant in writing: scheme name, scheme contact information, deposit amount, property address, landlord contact details, circumstances under which deductions may be made, the tenant’s right to dispute deductions, and the procedure for recovering the deposit at end of tenancy. Each scheme provides a template document covering all required information.

Step four — keep evidence of both registration and information delivery. The scheme registration provides its own evidence trail (a confirmation email or letter). The prescribed information delivery is best evidenced by either email with read receipt, signed paper acknowledgement, or recorded delivery. Verbal delivery does not count.

The 30 days runs against the calendar, not business days. Weekends and bank holidays are included. A landlord travelling at the deposit-receipt date should arrange the protection in advance — a deposit cannot be “held in a separate account pending protection” without breaching the law from day one.

Custodial versus insurance-based schemes

The two operational models for tenancy deposit protection London landlords choose between have distinct cash-flow, control, and risk profiles.

Custodial schemes (TDS Custodial, DPS, mydeposits Custodial): – The scheme holds the money. The landlord cannot access it during the tenancy. – Free at point of use for the landlord (interest on aggregated deposits funds the service). – At end of tenancy, both parties must agree on the distribution, or the dispute goes to scheme adjudication. – Simplest model for landlords without treasury operations. Recommended for owner-landlords with one to five properties.

Insurance-based schemes (TDS Insured, mydeposits Insured): – The landlord holds the money in their own bank account (or letting agent client account). – The landlord pays a per-tenancy insurance premium to the scheme — typically £20-£40 per tenancy. – At end of tenancy, the landlord proposes deductions; if the tenant disputes, the landlord must transfer the disputed amount to the scheme for adjudication. – Suits portfolios with active treasury management or where the deposit earns interest for the landlord.

The choice has cash-flow implications. Custodial schemes mean the landlord forgoes interest on the deposit money for the duration of the tenancy. Insurance-based schemes preserve the landlord’s interest but add an annual cost. For a single property, the difference is usually trivial. For a portfolio of 30+ properties, the cash-flow advantage of insurance-based can be significant.

The legal liability is identical in both cases. Both models provide statutory protection to the tenant; both expose the landlord to the same penalties for non-compliance.

The Tenant Fees Act deposit cap

Since the Tenant Fees Act 2019 commenced in June 2019, tenancy deposits have been capped:

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

The five-week cap is the operative limit for almost all London lettings. A property at £2,000 per month rent has an annual rent of £24,000, so the deposit cap is five weeks of rent — approximately £2,308. The previous custom of two months’ deposit (8.7 weeks) is no longer lawful for new tenancies.

Existing deposits taken before June 2019 at higher amounts can continue at those amounts for the current tenancy, but at any tenancy renewal or new tenancy the deposit must be reduced to the cap.

The cap creates real pressure on deduction precision. With a smaller deposit, a single contested deduction can exhaust the available pot. This is why professional inventories matter more under the cap regime — the cost of a £170 EICR being disputed when the deposit is £2,308 is substantial, and the evidence trail determines who absorbs the cost.

The Renters’ Rights Act 2025 did not change the cap. Earlier political drafts had proposed lowering the cap to four weeks; the final Act left the cap at five weeks.

End-of-tenancy deduction process

The deduction process is the operational core of tenancy deposit protection London law works around. The process has six concrete stages.

Stage one — check-out inspection. A professional inventory clerk re-inspects the property against the check-in report. The check-out report does not declare deductions; it documents condition. For the full operational distinction between check-in and check-out reports, see our check-in report vs check-out report guide.

Stage two — landlord’s deduction proposal. Based on the check-out report and any quotes for remedial work, the landlord prepares a written deduction request. This should itemise each proposed deduction with evidence (inventory reference, photograph, quote or invoice for remedial work). Hand-waving descriptions like “general cleaning” or “minor damage throughout” carry no weight at adjudication.

Stage three — communication to tenant. The landlord sends the deduction request to the tenant with all supporting evidence. The tenant has the opportunity to agree, partially agree, or dispute.

Stage four — agreement or dispute. If the tenant agrees, the landlord and tenant jointly instruct the scheme to release the agreed amounts. If the tenant disputes, the scheme’s adjudication process is triggered.

Stage five — adjudication. Both parties submit evidence to the scheme. An independent adjudicator reviews the evidence and makes a binding decision. The adjudicator’s decision is reasoned in writing and explains why each deduction was awarded or refused.

Stage six — distribution. The scheme releases funds according to the agreement or adjudication. For custodial schemes the scheme transfers from its account; for insurance-based schemes the landlord transfers from theirs (and may need to transfer additional funds to the scheme if the adjudication awarded the tenant more than the landlord initially held back).

The future S4.1 (deposit deduction guide) and S4.4 (what can a landlord deduct) spokes will cover the granular categories of deductions and their adjudication track record. The high-level principle: deductions for genuine damage beyond fair wear and tear are awarded; deductions for fair wear and tear are not; deductions without contemporaneous evidence rarely succeed regardless of merit.

How long can a landlord hold a deposit

The Housing Act 2004 framework that governs how long a landlord can hold a deposit at end of tenancy was not substantially amended by the Renters’ Rights Act 2025. The deposit must be returned within 10 days of the parties agreeing on the deductions (or none). If agreement cannot be reached, the deposit must be transferred to scheme adjudication.

What the post-RRA environment has changed is the surrounding pressure on timely landlord action:

• Expanded RRO exposure means landlords who delay or mishandle the deposit return face larger penalties — up to two years of rent on an RRO claim, with a two-year application window for tenants.
• Possession blocking persists — a landlord with an unprotected or improperly handled deposit cannot recover possession under the new Section 8 regime until the position is regularised.
• Local authority enforcement expanded on 27 December 2025, with new investigatory powers that can compel landlords to provide documents.

In practice this means landlords need to act faster and more carefully at check-out than under the previous regime, even though the underlying statutory timeline did not change. The check-out inventory, comparison to check-in, and documented deduction request are now time-critical because slow or sloppy handling exposes the landlord to penalties that have grown substantially in scale.

For the full operational picture — what triggers each timer, what counts as “agreement on deductions,” and what happens when negotiations stall — see our dedicated how long can a landlord hold a deposit spoke.

The evidence required for deductions

Adjudication outcomes under tenancy deposit protection London schemes are decided on evidence. The hierarchy of evidence weight is consistent across all three schemes:

Strongest evidence — combined AIIC-format check-in and check-out reports. A professional inventory at move-in plus a matched check-out comparison, signed by the tenant at check-in and produced in the AIIC standardised format, is the gold standard. Adjudicators are trained in the AIIC vocabulary; the matched-pair documentation establishes the change between the two points with clarity that no other evidence type matches.

Strong evidence — independent inventory plus tenant-signed acknowledgement. A professional inventory not in AIIC format but produced by an independent clerk and signed by the tenant. Less optimal but still well-weighted.

Moderate evidence — agent or landlord-produced inventory with tenant signature. Carries the implicit bias concern (the producer has a stake in the outcome) but the signature gives some weight.

Weak evidence — photographs only, with no contemporaneous written narrative. Photographs carry weight only when their context (date, location, what they show) is verifiable. Loose photographs without inventory framing are often rejected.

Negligible evidence — texts, emails, verbal descriptions, after-the-fact reports. Adjudicators do not weight evidence produced after the dispute has arisen as comparable to contemporaneous documentation.

For the full picture of inventory framework and the six AIIC sections, see our property inventory reports London guide. For a worked example with redacted screenshots, see our inventory report example guide. For the matched check-in / check-out documentation pattern, see check-in report vs check-out report.

The adjudication process and outcomes

When a deposit dispute goes to scheme adjudication, the scheme appoints an independent adjudicator who reviews evidence from both parties and issues a binding decision. The process is on-paper rather than oral — there is no hearing, no cross-examination, no advocate. Both parties submit evidence; the adjudicator weighs it; the decision is issued in writing.

Typical timelines: – Time from dispute referral to evidence deadline: 14 days – Time from evidence deadline to decision: 28 days – Total: approximately 6 to 8 weeks from dispute to outcome

Decision distribution across the deposit protection schemes consistently shows: – Roughly 40% of disputed claims awarded fully or substantially in the landlord’s favour – Roughly 40% awarded fully or substantially in the tenant’s favour – Roughly 20% split awards (partial in each direction)

Underneath those averages sits a much sharper pattern: landlords with strong evidence (professional AIIC inventory + photographic documentation + receipts/quotes for remedial work) win the great majority of their disputes. Landlords without contemporaneous evidence lose the great majority of theirs. The decision is not random — it is evidence-driven.

Common decision categories: – Fair wear and tear — claims for general “wear” are routinely rejected as fair wear and tear, particularly for paintwork, carpets in high-use areas, and minor appliance wear – Cleaning — only awarded where the property was demonstrably cleaner at check-in than at check-out, and where the landlord has commissioned (not just estimated) professional cleaning – Damage — awarded where the check-in/check-out comparison demonstrates change beyond wear and tear, supported by remedial cost evidence – Replacement of items — awarded only with appropriate depreciation; a five-year-old carpet damaged at year five is not awarded the cost of a new carpet but a depreciated proportion

The scheme adjudication decision is final. There is no appeal except on procedural grounds (e.g., evidence not considered). A party who disagrees with the decision can pursue the matter through county court, but in practice that route is rarely used because the scheme decision is presented in court as authoritative.

Renters’ Rights Act 2025 deposit changes

The Renters’ Rights Act 2025 commenced on 1 May 2026 but the deposit protection framework itself remained substantially unchanged. The Housing Act 2004 deposit protection regime (30-day rule, prescribed information, approved schemes, civil compensation of 1-3× the deposit) continues to apply in the same form. The cap at five weeks’ rent (or six weeks for higher-rent tenancies) under the Tenant Fees Act 2019 also remains in place — the Act did not lower the cap further despite earlier political proposals.

What did change is the wider enforcement architecture around deposit failures:

First, deposit protection remains a structural precondition to possession. A landlord cannot recover possession under any Section 8 ground unless the deposit has been protected in an authorised scheme and prescribed information has been provided to the tenant. This is one of only two compliance obligations under the post-1 May 2026 regime that retain “technical bar” status — the other being landlord database registration once Phase 2 activates in late 2026/2027. A landlord who failed to protect on time can still recover possession if they remedy the position before the possession hearing (the deposit must be protected and the prescribed information served), but financial penalties for the original failure still apply.

Second, Rent Repayment Orders have been substantially expanded. Tenants now have up to two years (up from twelve months) to apply for an RRO, and can recover up to two years of rent (up from twelve months). The maximum RRO penalty was doubled by the Act. Repeat offenders are required to pay the maximum amount. RROs were extended to superior landlords. While the 1-3× deposit compensation under Housing Act 2004 remains the direct remedy for deposit protection failure, sustained or repeated breaches now also expose the landlord to RRO claims under the broader regulatory framework.

Third, local authority enforcement powers expanded on 27 December 2025. Local authorities now have powers to demand documents from landlords, letting agents, and property portals, and to enter premises to investigate suspected breaches. Deposit disputes that surface evidence of broader compliance failures (no Gas Safety, no EICR) can be referred for separate enforcement.

The deposit dispute timeline through the scheme adjudicators (TDS, DPS, mydeposits) themselves was not changed by the Act. Each scheme’s adjudication workflow continues unchanged — typically 14 days for evidence submission, 28 days for the decision.

Penalties for failing to protect a deposit

The penalties for non-compliance with tenancy deposit protection London law are severe and routinely awarded:

The penalty cap is three times the deposit amount per tenancy. For a London property with a deposit of £2,000, the maximum civil compensation is £6,000 — separate from any RRO under the Renters’ Rights Act framework, which can add up to 12 months’ rent on top.

Crucially, the penalty applies whether the landlord’s failure was wilful or accidental. A landlord who genuinely forgot to protect a deposit faces the same liability as one who deliberately held the money. The “honest mistake” defence is not available.

The penalty operates retrospectively. A landlord who let in 2010 and continues the tenancy can face a 2026 claim for deposit protection failures that occurred fifteen years earlier — the limitation period runs from the failure rather than from a fixed date, and the failure persists for the duration of the non-compliance.

Frequently asked questions

Does tenancy deposit protection London law apply to lodger agreements?

No — lodger agreements where the landlord lives in the property are not assured tenancies and fall outside the scheme. The arrangement is governed by separate contract law. Most house-share arrangements in London, however, are not lodger agreements — they are assured tenancies and the deposit must be protected.

Can the tenant pay rent in advance instead of a deposit?

The Renters’ Rights Act 2025 introduced strict rules on rent in advance from 1 May 2026. Before a tenancy agreement is signed, there is an absolute prohibition on landlords accepting or inviting any rent payments. After the agreement is signed, the landlord can require one month’s rent (or 28 days for shorter rental periods) plus the deposit. During the tenancy, any provision requiring more than one month’s rent in advance is void. Rent in advance is not a deposit in legal terms — it cannot substitute for the statutory deposit protection requirement. A landlord who takes a deposit must protect it; the rent-in-advance restrictions do not change that.

What happens if I forgot to protect the deposit?

Protect it immediately and provide the prescribed information. The 30-day window has closed, but bringing the deposit into protection now reopens the ability to serve possession notices in due course. The civil compensation penalty remains payable if the tenant brings a claim, but late protection mitigates the penalty (adjudicators and courts have discretion within the 1–3× range and late compliance moves the award toward the lower end).

Can a letting agent take the deposit on my behalf?

Yes. Most managed lets have the letting agent receive the deposit and arrange protection on the landlord’s behalf. The legal responsibility remains the landlord’s — if the agent fails to protect, the landlord is liable to the tenant. Contracts between landlord and agent should explicitly assign the responsibility and provide for indemnity.

Which scheme is best for a London landlord?

For a single property or small portfolio (one to five properties), DPS Custodial is the most common choice — free, simple, scheme holds the money. For larger portfolios with active treasury management, TDS Insured allows the landlord to retain interest on the deposits at the cost of an annual insurance premium. The future S4.3 spoke will compare the three schemes in more detail.

What if the deposit is paid in instalments?

The 30-day clock starts on the first instalment payment, not on full receipt. A deposit paid as £500 on day one and £1,500 on day fifteen must be fully protected by day thirty from the first payment.

How is interest on the deposit handled?

Custodial schemes typically retain interest to fund the scheme’s operations. Insurance-based schemes leave interest with the landlord (because the landlord holds the money). The tenant is not entitled to interest on the deposit during the tenancy in either model.

Does tenancy deposit protection London apply to short-let properties?

Standard short-lets (under 90 days) are not typically assured tenancies — they are licences or holiday lets governed by different rules. Mid-term lets (90 days to 6 months) often blur the line. Where the arrangement is an assured tenancy, deposit protection applies; where it is a different legal form, it does not. The classification matters and is worth checking with a property law specialist for borderline cases.
