Security deposits: taking, holding and returning them

Almost every deposit dispute is lost before it starts — at check-in, by a landlord who took no usable evidence of the condition of the property.

For landlords and property teams · 10 min read · Updated 2026-09-13

Deposit disputes are decided by evidence, and the evidence has to exist before the dispute does. By the time a tenant is arguing about a carpet, the only question is what you recorded on the day they moved in. If the answer is “nothing much”, you will lose, and you will deserve to.

This is the one area of letting where an hour of work at the start reliably saves a week of argument at the end.

At the start: what to record when you take it

Write down, and keep:

  • The amount, the date received, and who paid it — the tenant, a guarantor, or a third party. This matters at the end, because the money generally goes back to whoever sent it.
  • What it covers. Damage and unpaid rent is the usual scope. If it also covers cleaning, missing keys or unpaid utilities, that has to be written into the tenancy agreement, not assumed.
  • Where it is held, and under which protection scheme where one applies.
  • The prescribed information, where your jurisdiction requires you to give the tenant specific written details within a deadline.

Deposit rules vary more than almost anything else in letting. Many jurisdictions cap the amount, require the money to be held in a separate or government-backed scheme, set a deadline for protecting it and for notifying the tenant, require interest to be paid, and impose real penalties for getting it wrong — sometimes several times the deposit. Some have none of this. Check what applies where the property is before you take the money, not after.

The condition report is the whole case

An inventory or condition report is not paperwork. It is the baseline against which every later claim is measured, and it is the single document that decides most disputes.

A report that works:

  • Is dated and photographic. Photographs with a verifiable date, taken in daylight, of every room, plus close-ups of anything already damaged, worn or marked.
  • Describes condition, not just existence. “Carpet, bedroom 1” proves nothing. “Carpet, bedroom 1 — good condition, light wear at doorway, no stains” proves something.
  • Records meter readings and the number of keys handed over. Both are argued about surprisingly often.
  • Is agreed by the tenant. A signature, or an email in which they confirm it, or a stated window in which they could dispute it and did not. An unagreed inventory is your word against theirs, which is no better than having none.

Do the same thing at the end, in the same order, ideally from the same camera positions. Two sets of comparable photographs are worth more than any amount of description.

The check-out photograph rule. Take the end-of-tenancy photographs before any cleaning or repair work starts. Once a contractor has been in, you can no longer show what the tenant left behind — only what it looked like after somebody tidied it.

Fair wear and tear, and the line that decides deductions

You are entitled to be put back in the position you would have been in had the tenant met their obligations. You are not entitled to a better property than you let.

The distinction adjudicators apply almost everywhere, whatever the local wording:

  • Wear and tear — deterioration from ordinary use over the length of the tenancy, given the number of occupants and the age and quality of the item. Not deductible.
  • Damage — deterioration beyond that, from negligence, misuse or neglect. Deductible.

Two principles limit even a valid claim:

Betterment. If a tenant ruins a seven-year-old carpet with a notional ten-year life, you cannot claim a new carpet. You claim the remaining value they destroyed — roughly three-tenths of it. A landlord who claims full replacement cost for a worn item generally loses the whole deduction, not just the excess.

Proportion. A damaged section is not always a whole-room claim. Sometimes it is: a burn in the middle of a fitted carpet cannot be patched invisibly. Argue the point; do not assume it.

Making a deduction that holds up

Each deduction needs four things, and a claim missing any one of them is weak:

  1. Evidence of the original condition — the check-in report.
  2. Evidence of the final condition — the check-out report.
  3. Evidence of cost — a quote or invoice, not an estimate you made up. Two quotes are better than one.
  4. An adjustment for age and wear, shown explicitly rather than hidden in the number.

Present it as an itemised statement: item, what happened, what it cost, what you have deducted after allowing for age. Tenants accept itemised deductions far more often than round numbers, because a round number looks like a guess and usually is.

Returning it

Most jurisdictions set a deadline for returning the undisputed part of a deposit, commonly somewhere between ten days and a month from the end of the tenancy or from agreement being reached. Two habits help regardless of the local rule:

  • Return the undisputed portion immediately. If you are claiming 200 of a 1,500 deposit, send back 1,300 now. Holding the whole sum while you argue about a fraction of it turns a small disagreement into a formal dispute.
  • Put the reasoning in writing at the same time, with the evidence attached. A deduction explained on the day is a negotiation; the same deduction explained three weeks later, after chasing, is a complaint.

The five-minute file

For each tenancy, one place containing: the signed agreement, the deposit record and protection certificate, the check-in report with photographs, the check-out report with photographs, quotes and invoices for any deduction, and the correspondence in which deductions were proposed and answered.

If assembling that takes you more than five minutes, the filing is the problem — and it will be a much bigger problem on the day somebody gives you a deadline to produce it.

How BuildingHQ handles it

Deposits are recorded against the tenancy with the amount, date and who paid. Inspection reports, photographs, quotes and invoices attach to the unit and the tenancy rather than sitting in a folder somewhere, so the check-in and check-out evidence stays together and stays findable years later. Deductions are recorded as itemised entries against the deposit, not as an adjustment to the rent ledger.
