If you rent a property in England or Wales, the deposit you hand over is likely one of the biggest single payments you’ll make outside of your monthly rent. Under the rules that have been in place since 2007, that money must be protected in a government-authorised scheme within 30 days of the landlord receiving it. Miss that deadline, and a tenant can claim between one and three times the deposit amount through the county court. For a typical deposit of around £1,200, that means a potential claim of up to £3,600 — and the landlord’s ability to evict using a Section 21 notice is blocked until they comply.

These rules apply to assured shorthold tenancies (ASTs) in England and Wales. They don’t cover company lets, tenancies with an annual rent over £100,000, or certain other arrangements. The system exists to stop landlords from unfairly holding onto deposits and to give tenants a clear route to dispute deductions without going straight to court. Here’s what you actually need to know.
The central concept here is tenancy deposit protection — the legal requirement that a deposit paid under an AST must be held in one of three approved schemes. It’s not optional, and it’s not something a landlord can opt out of by agreement with the tenant.
What I tend to notice is that most disputes come down to timing and paperwork — not the amount of the deposit itself. If you’re a tenant, the first thing I’d check is whether your deposit was protected within 30 days of payment. If you’re a landlord, the single most common mistake is missing that deadline by even a day. For a deeper look at how the broader rental landscape works, you might find this guide to rental protections in the UK useful.
How the deposit cap and rent in advance rules work
The five-week deposit cap from the Tenant Fees Act 2019 is still in place. To calculate the maximum deposit, you take the monthly rent, multiply by 12, divide by 52 to get the weekly rent, then multiply by five. For a property renting at £1,200 per month, the weekly rent is £276.92, and the maximum deposit is £1,384.62. If the annual rent is £50,000 or more — roughly £4,167 per month — the cap rises to six weeks’ rent.
What changed under the Renters Rights Act 2025, which came into force on 1 May 2026, is the limit on rent in advance. Before the tenancy is signed, a landlord cannot ask for or accept any payment of rent. After both parties have signed, they can request a maximum of one month’s rent in advance. Any clause in the tenancy agreement that requires rent in advance beyond the current rental period is now unenforceable. Landlords who used large advance payments to offset risk from tenants with weaker credit or limited UK references now need to use a guarantor or rent guarantee insurance instead.
The deposit itself must still be protected in one of the three approved schemes. The custodial option is free — the scheme holds the money. The insured option costs an annual fee, but the landlord holds the deposit and the scheme guarantees it if the landlord fails to return it. DPS offers both custodial and insured. MyDeposits charges from around £17.76 for insured. TDS charges from around £20.40 for insured. For a landlord managing multiple properties, a tracker system to monitor protection deadlines is worth considering.
Common mistakes that cost landlords and tenants
Missing the 30-day deadline by even a day
The clock starts when the money is received, not when the tenancy starts or the agreement is signed. A holding deposit converted to a tenancy deposit triggers the clock at conversion. If a landlord protects the deposit on day 31, the tenant can still claim compensation for the period it was unprotected, and the Section 21 notice is blocked until compliance is complete. The compensation claim can be between one and three times the deposit amount. For a £1,200 deposit, that’s a potential £3,600 claim. What I’d do as a landlord is set a calendar reminder for day 25 after receiving any deposit — that gives a five-day buffer.
Using a non-approved scheme or no scheme at all
Only DPS, MyDeposits, and TDS are government-authorised. Using any other arrangement — holding the deposit in a personal account, using an unapproved insurance product, or simply keeping it in the landlord’s current account — counts as non-compliance. The penalties are the same: compensation claims, blocked possession orders, and from May 2026, local authorities can issue civil penalties of up to £7,000 for first or minor offences and up to £40,000 for serious or repeat offences.
Failing to serve prescribed information to all tenants
Prescribed information must be given to every tenant and anyone who paid the deposit on their behalf. It must include the property address, the deposit amount, which scheme holds the money, the landlord’s and agent’s contact details, the dispute resolution process, and the circumstances under which deductions can be made. If one tenant doesn’t receive it, the protection is incomplete. The same 30-day window applies. Getting written confirmation of receipt from each tenant is the safest approach.
Poor documentation at check-in and check-out
Without a signed inventory at the start and end of the tenancy, dated photographs, receipts for cleaning or repairs, and correspondence about damage during the tenancy, a landlord has little evidence to support deductions. The scheme’s free Alternative Dispute Resolution (ADR) service relies on this documentation. If the evidence isn’t there, the adjudicator is likely to rule in the tenant’s favour. For tenants, keeping your own dated photos at move-in and move-out is the best protection against unfair deductions.
What the end-of-tenancy deposit return process actually looks like
Agreeing on deductions and releasing the deposit
At the end of the tenancy, the landlord and tenant conduct a checkout inspection. If they agree on any deductions — for unpaid rent, damage beyond fair wear and tear, or missing items — they document the amount and request release through the scheme. Custodial schemes typically release the funds within 10 days of agreement. If the landlord holds the deposit under an insured scheme, they return it directly within the same 10-day window.
What happens when there’s a dispute
If the landlord and tenant can’t agree on deductions, the landlord must notify the tenant in writing with evidence. Either party can then use the scheme’s free ADR service. The tenant submits their evidence — signed inventory, photos, receipts, correspondence — and an independent adjudicator reviews it. The adjudicator’s decision is binding on both parties. The process typically takes several weeks. Court action is possible but rare, since the ADR is free and faster.
The evidence that wins or loses a dispute
The adjudicator looks for a signed inventory at the start and end of the tenancy, dated photographs showing the condition at both points, receipts for cleaning or repairs, and any correspondence about damage during the tenancy. Without these, a claim for deductions is unlikely to succeed. For tenants, taking photos on the day you move in and emailing them to yourself with a date stamp is a simple way to protect yourself. For landlords, a professional inventory service at check-in and check-out is money well spent.
How the Renters Rights Act 2025 changes possession rules
From 1 May 2026, most Section 8 possession grounds are blocked unless the deposit is properly protected and prescribed information has been served. This is a significant change. Previously, only Section 21 notices were blocked. Now, a landlord who hasn’t complied with deposit protection rules can’t evict using most Section 8 grounds either — except for serious criminal or anti-social behaviour. This means non-compliance effectively traps the landlord with the tenant until they fix the issue.

Why getting deposit protection right matters more than ever
The Renters Rights Act 2025 didn’t overhaul the deposit protection system, but it closed a major loophole. From May 2026, a landlord who hasn’t protected the deposit or served prescribed information can’t use most Section 8 possession grounds either. That means non-compliance doesn’t just block a no-fault eviction — it blocks eviction for rent arrears, damage, and most other grounds too. The only exceptions are serious criminal or anti-social behaviour. For tenants, this is a powerful protection. For landlords, it makes compliance non-negotiable.
