How Long Does a Landlord Have to Return a Deposit?

When a tenancy ends, "how long do I have to give the deposit back?" is one of the most-searched landlord questions — and one of the most misunderstood. The answer is not "within 10 days of the tenant moving out". It is within 10 days of you and the tenant agreeing how much comes back. Those are very different clocks, and mixing them up is how landlords end up accused of holding a deposit too long.

This guide is the plain-English version: exactly what starts the 10-day clock, what you can lawfully take off, what happens if you cannot agree, and how the whole thing runs differently depending on which scheme holds the money.

This is guidance, not legal advice. Deposit rules are set by the Housing Act 2004 and your scheme's terms — check your scheme and GOV.UK for your own situation.

The 10-day rule, precisely

Once you and the tenant have agreed the amount to be returned, the deposit (or the agreed portion of it) must be repaid within 10 calendar days of that agreement.

The key word is agreed. The clock does not start when the tenant moves out; it starts when there is an actual agreement on the figure. So if the tenant leaves on the 1st but you do not settle the deductions until the 20th, you have until the 30th to pay — and you are not "late" for the first 19 days, because there was nothing agreed yet.

One trap: silence is not agreement. If you email the tenant proposing deductions and they never reply, that is not them agreeing — it is an open dispute. Agreement means the tenant has clearly confirmed, usually in writing, that they accept the figure.

What you can lawfully deduct

You can only take money off for a genuine loss you can evidence. In practice that is:

Every one of those turns on evidence, which means the check-in inventory and the check-out report are what actually win or lose the money. A dated, photographed inventory that both sides signed is the difference between a deduction that sticks and one an adjudicator throws out. "It looked worse than before" without a check-in record almost always fails.

What happens if you cannot agree

If the tenant disputes your deductions, you do not get to just keep the money, and you should not sit on the whole deposit either. Two things happen:

Custodial vs insured: who actually holds the money

How the return happens depends on which type of scheme you used:

Either way the 10-day-from-agreement rule applies; the difference is just whether the money is in your account or the scheme's.

Get this wrong and it is not just the deposit

The return timeline sits on top of the protection rules, and those carry the real teeth. If the deposit was never protected, or the Prescribed Information was never served, a tenant can claim one to three times the deposit and you lose the ability to use certain possession grounds until it is put right. A slow return on a properly protected deposit is a smaller problem than a deposit that was never protected correctly in the first place — but both are avoidable with a system that tracks the dates.

How LetCompliance helps: the deposit, its protection deadline, the check-in inventory and the check-out evidence all sit on the same tenancy, so when it ends you have the record an agreement (or an adjudicator) is built from — and the 10-day clock is one you can actually see.
