When a rental property changes hands, two very different pots of money are often confused with each other: the holding deposit paid to reserve the property, and the tenancy deposit that protects the landlord for the life of the tenancy. They're governed by different rules, different caps and different deadlines — and mixing them up causes stress, crossed wires and avoidable deposit disputes.
Here's exactly how each one works, the deadlines that matter, and how landlords and tenants can stay on the right side of both.
A holding deposit is a short-term, up-front payment that reserves a rental property while referencing and paperwork are completed. In England and Wales, holding deposits are capped at one week's rent under the Tenant Fees Act 2019 — it isn't a fee, but a temporary stake that should either be deducted from the first month's rent or returned, depending on how things progress. In Scotland, holding deposits cannot be charged at all.
Once a holding deposit is paid, a default "deadline for agreement" of 15 days applies for both parties to progress to a signed tenancy agreement (a different deadline can be agreed in writing).
The holding deposit rules from there are straightforward:
Two pieces of good practice sit alongside the cap: once a holding deposit is taken, the property should come off the market, and a landlord should never hold two holding deposits on the same property at the same time. Setting the conditions out in writing before any money changes hands prevents nearly every argument later.
A tenancy deposit (also called a security deposit) is the larger sum held for the duration of the tenancy, protecting the landlord against rent arrears and damage beyond fair wear and tear.
In England, tenancy deposits are capped at five weeks' rent where the annual rent is under £50,000, and six weeks' rent above that.
This is where landlords most often get caught out. Every tenancy deposit on an assured shorthold tenancy must be protected in a government-approved deposit protection scheme within 30 days of receipt. Protection alone isn't enough — the landlord must also serve the tenant with the scheme's prescribed information within the same 30-day window.
Get either wrong and two serious consequences follow:
These are not idle technicalities: courts enforce both, and deposit compliance failures are among the most common reasons possession claims collapse.
It's also worth noting that under the Renters' Rights Act, Section 21 is being abolished — but deposit protection compliance remains just as critical, as courts will still expect full compliance in possession proceedings under the new grounds.

In England and Wales, landlords choose from three government-approved deposit protection schemes: the Tenancy Deposit Scheme (TDS), the Deposit Protection Service (DPS) and mydeposits. Each offers two routes:
Whichever scheme and route you choose, end-of-tenancy deposit disputes are handled through the scheme's free alternative dispute resolution (ADR) service — and that's where the quality of your evidence decides everything.
The most common flashpoints — professional cleaning, wear versus damage, garden condition, missing keys — are rarely about the law. They're about evidence.
Adjudicators award deductions based on documented change in condition, and the burden of proof sits with the landlord. A dated, independent inventory and check-in report at the start of the tenancy, and a professional check-out report at the end, make ADR decisions straightforward. Without them, even perfectly reasonable deductions are routinely knocked back — regardless of the actual damage.
This is precisely why experienced landlords treat the professional inventory as part of compliance, not an optional extra. The deposit protection certificate proves the deposit was handled lawfully; the inventory proves what the deposit deduction is actually for.
For landlords and agents:
For tenants:
Reserve with a holding deposit (England and Wales only, capped at one week's rent), agree a written deadline, and be transparent through referencing. Once the tenancy starts, protect the deposit in an approved scheme within 30 days and serve the prescribed information. Choose custodial for simplicity or insured for control — and in both cases, keep immaculate records. If a deposit dispute arises, your inventory, check-out report and dated photographs will do the heavy lifting.
