Tenancy deposit explained: protection, deadlines and disputes
A tenancy deposit is money a tenant pays a landlord or letting agent at the start of a tenancy as security against unpaid rent, damage or cleaning costs, held on the basis that it is returned in full at the end unless the landlord can evidence a deduction.
How tenancy deposit protection works in England and Wales
For assured shorthold tenancies, a deposit taken by a landlord or an agent must be placed in one of three government-approved schemes within 30 days of receipt, and the tenant must be given the prescribed information about where it is held within the same period. That is the position set out in the gov.uk guidance on tenancy deposit protection.
Each approved scheme offers two models.
- Custodial. The scheme holds the money for the length of the tenancy, free to the landlord.
- Insured. The landlord or agent keeps the money and pays the scheme a fee or premium to protect it.
Around 4.7 million deposits were protected across England and Wales in 2024/25, split roughly 54% custodial and 46% insured, according to the Statistical Briefing published by TDS, one of the approved schemes. The average protected deposit reached £1,175.
What happens if a deposit is not protected?
The consequences fall on the landlord and they are not trivial. Under the gov.uk guidance, a court may order the landlord to repay the deposit or to protect it within 14 days, and may order a payment to the tenant of up to three times the deposit.
There is a second consequence that tends to matter more commercially. Where a deposit was not protected as it should have been, the court may decide the tenant does not have to leave when the tenancy ends, which closes off the no-fault possession route until the position is put right.
How much can a tenancy deposit be?
Since 1 June 2019 the Tenant Fees Act 2019 has capped deposits in England: five weeks' rent where the annual rent is under £50,000, and six weeks' rent where the annual rent is £50,000 or more. A holding deposit is capped separately at one week's rent. Weekly rent for the calculation is the monthly rent multiplied by 12 and divided by 52, which is not the same as dividing a month by four.
The rules are not the same across the UK
Treating the England and Wales regime as universal is one of the more expensive mistakes in this area, and it catches landlords and agents holding property in more than one nation.
- Scotland. Three separate approved schemes, and the deposit must reach one of them within 30 working days of the tenancy starting, not 30 calendar days.
- Northern Ireland. A deposit must be protected within 28 days of receipt, with prescribed written information to the tenant within 35 days, per nidirect.
- Everywhere else. Ireland, the Netherlands, Germany, Australia and the rest all run their own frameworks. Some have a scheme, some cap the amount instead, some route disputes straight to a tribunal or the courts.
Check the regime for the property's location before quoting a deadline to a landlord. Deposit rules also move: they are a standing target for housing legislation in every UK nation.
How are deposit disputes decided?
Each approved scheme in England and Wales offers free alternative dispute resolution as a substitute for a county court claim. An adjudicator reads the submissions from both sides and decides. The process is documentary, and nobody visits the property.
Two things follow from that, and letting agents feel both.
- The burden sits with whoever is claiming. A landlord seeking a deduction has to evidence it, not simply assert it.
- The papers are the case. A dated check-in report and a matching check-out report are worth more than a page of recollection, however sincere the recollection is.
Formal disputes stay uncommon. TDS reported about 1% of protected deposits going to adjudication in the 12 months to March 2025, some 46,950 cases, with cleaning appearing in 54% of disputes and damage in 49%.
Tenancy deposit example: the £480 claim
A landlord claims £480 from a £1,200 deposit for cleaning and a damaged blind. The check-in describes the flat as professionally cleaned and photographs it; the check-out shows a kitchen left below that standard and a broken slat.
The adjudicator awards the cleaning in full against the invoiced cost, and a reduced sum for the blind reflecting its age. The claim succeeded on paperwork produced during a routine property inspection sequence, months and years before anyone knew there would be an argument.
