Tenancy Deposit Protection Scheme Rules for Landlords (2026)

Why deposit protection exists

Before 2007, tenants had little recourse if a landlord unfairly withheld a deposit at the end of a tenancy. The Housing Act 2004 introduced mandatory tenancy deposit protection to fix this, requiring every deposit taken for an assured shorthold tenancy in England and Wales to be placed in a government-approved scheme, with strict deadlines and penalties for landlords who fail to comply.

The 30-day rule and prescribed information

From the date you receive a deposit, you have 30 days to:

1. Place the deposit in one of the three approved schemes (DPS, MyDeposits or TDS).
2. Give the tenant the scheme's prescribed information in writing, including how the deposit is protected and how disputes are resolved.

Missing either requirement — not just failing to protect the money at all — puts you in breach and exposes you to penalties.

Worked example 1: Calculating the maximum deposit

Nathan is letting a flat at £1,400 per month (£16,800 per year, under the £50,000 threshold), so the maximum deposit he can legally take is 5 weeks' rent.

• Weekly rent: £1,400 × 12 ÷ 52 = £323.08
• Maximum deposit: 5 × £323.08 = £1,615.38

If Nathan asked for £1,800, he would be charging a banned fee and could face a financial penalty from the local council of up to £5,000 for a first offence.

Worked example 2: The cost of late protection

Sadia takes a £1,200 deposit but does not protect it until day 45 — 15 days late.

If the tenant takes Sadia to court, the judge can award a penalty of between 1x and 3x the deposit amount. Assuming a mid-range penalty of 2x:

• Penalty: 2 × £1,200 = £2,400
• Plus the original deposit must still be returned or accounted for at the end of the tenancy

Sadia's late protection, even by just 15 days, could cost her £2,400 in penalties alone — a stark illustration of why the deadline should never be missed, regardless of how busy a landlord is.

Worked example 3: A disputed deduction resolved through ADR

At the end of a tenancy, Priya (the landlord) wants to deduct £450 from a £1,300 deposit for professional cleaning and a damaged carpet. The tenant disputes the full amount, claiming the flat was left clean and the carpet mark was pre-existing.

Because Priya cannot reach agreement with the tenant, she raises a dispute through her scheme's free Alternative Dispute Resolution service. The adjudicator reviews the check-in and check-out inventories (with photos) and receipts:

• Cleaning receipt (£120): the check-in inventory shows the property was professionally cleaned before move-in and the check-out inventory shows it was not — deduction upheld
• Carpet damage (£330): the check-in inventory photo already shows a similar mark in the same location — deduction rejected

Outcome: Priya recovers £120, and the remaining £1,180 (£1,300 minus the upheld £120) is returned to the tenant. This example shows why a thorough, photographed inventory at both check-in and check-out is the single most valuable piece of evidence in any deposit dispute.

Protecting your rental business

Getting deposit protection right is one of the most basic but highest-risk compliance areas for landlords — mistakes are cheap to avoid but expensive to fix after the fact. If you are assessing whether a rental property will be profitable once you account for compliance costs, insurance, and potential void periods, a Buy-to-Let Calculator and Rental Yield Calculator can help you build a realistic picture of net returns.

Practical compliance checklist

1. Protect the deposit within 30 days, without exception.
2. Send the prescribed information in writing within the same window, keeping a copy for your records.
3. Never charge more than the 5 or 6-week cap.
4. Complete a thorough check-in and check-out inventory with dated photographs every single tenancy.
5. Use the scheme's free ADR service rather than going to court if a dispute arises.
