Deposit protection: avoiding the most common landlord mistakes

Of all the compliance jobs in lettings, deposit protection should be the easiest: take the deposit, protect it, serve the paperwork. Yet it remains one of the most common and most expensive mistakes self-managing landlords make, because the rules are strict, the deadlines are short and the penalties do not care whether the error was innocent.

The rules in brief

• A deposit on an assured tenancy must be protected in a government-approved scheme within 30 days of receipt
• The prescribed information, telling the tenant where and how it is protected, must be served within the same 30 days
• Deposits are capped at five weeks’ rent for most tenancies (six weeks where the annual rent is £50,000 or more)
• Get it wrong and a court can order compensation of one to three times the deposit, per tenancy, per breach

There are three approved schemes in England: the DPS, TDS and mydeposits. Each offers a custodial option, where the scheme holds the money, and an insured option, where the landlord or agent holds it and pays a fee. Which scheme you use matters far less than using one properly and on time.

The mistakes we see most

The classic error is simple lateness: the tenancy starts in a busy week, the deposit sits in a bank account, and day 30 slips past unnoticed. Late protection cannot be fully cured; even if you protect the money afterwards, the breach has happened and the tenant can still claim.

Close behind is protecting the deposit but forgetting the prescribed information, or serving it incompletely. The paperwork is as much a legal requirement as the protection itself. We also see deposits taken above the cap, often accidentally when a “pet deposit” is added on top, and holding deposits mishandled at the application stage, where the rules on what can be kept and when are tighter than many people realise.

Finally, renewals trip people up. Where a tenancy changes, depending on the scheme and how the deposit was protected, the protection and paperwork may need refreshing. It is an easy step to miss years into a tenancy.

Why it matters more than ever

Under the Renters’ Rights reforms, compliance failures increasingly block a landlord’s route to possession. A deposit problem that once looked like a technicality can now stall proceedings at exactly the moment a landlord needs them to work, on top of the direct financial penalty. Clean paperwork has become the foundation of a landlord’s legal position, not an optional extra.

Getting the end of tenancy right too

Protection is only half the story; the deposit also has to come back fairly. Deductions succeed on evidence, which means a detailed check-in inventory, mid-term inspection notes and a proper check-out report with photographs. Without them, adjudicators side with the tenant, because the burden of proof sits with the landlord. Fair wear and tear is not deductible, and adjudicators know the difference.

Or never think about it again

For fully managed landlords, all of this is our job: we protect every deposit on time, serve the paperwork, hold the evidence trail from check-in to check-out and handle any dispute through the scheme’s free adjudication service. It is one of those quiet pieces of process that you only notice when it has not been done.
