How to Protect a Tenancy Deposit in England: Step-by-Step for Landlords

The Clock Starts When You Receive the Money

For a deposit taken in connection with an assured tenancy, the 30-calendar-day countdown under Section 213 of the Housing Act 2004 begins when you or your letting agent receive the funds. Within that window, you must do two things: lodge the deposit with an approved scheme, and serve the statutory Prescribed Information on every tenant and any third-party payer. Miss either step and you face a court-ordered penalty of one to three times the deposit.

Since 1 May 2026, the Renters' Rights Act 2025 has converted all Assured Shorthold Tenancies into Assured Periodic Tenancies. The deposit protection rules still apply in full — if anything, the penalties bite harder because you can no longer serve a Section 21 notice while non-compliant.

Choose One of the Three Approved Schemes

England has exactly three government-authorised deposit protection schemes. Each offers both a custodial and an insured option:

• DPS (Deposit Protection Service) — operated by Computershare Investor Services
• TDS (Tenancy Deposit Scheme) — operated by The Dispute Service Limited
• mydeposits — operated by HF Resolution Limited, backed by the NRLA

Under the custodial model, you transfer the deposit to the scheme and it holds the money in a ring-fenced account. This is free for every landlord.

Under the insured model, you keep the deposit in your own bank account and pay the scheme a per-deposit fee or membership to insure it. Fees range from around £18 to £28 per deposit depending on the scheme and deposit size.

For a single-property self-managing landlord, the custodial route is the straightforward choice: zero cost, and you never have to worry about ringfencing funds separately.

The Step-by-Step Process

Day 0 — Receive the deposit. Record the exact date, amount and payment method. Issue a written receipt. This date starts the 30-day clock.

Days 1–2 — Check the deposit cap. For an assured tenancy with annual rent up to £100,000, the Tenant Fees Act 2019 caps the deposit at five weeks' rent below £50,000, or six weeks' rent from £50,000 to £100,000 inclusive. The Act does not cover tenancies with annual rent above £100,000. The formula: (monthly rent × 12) ÷ 52 × 5 or 6, depending on the threshold. Round down — exceeding the cap by even a penny creates a prohibited payment.

Days 1–15 — Register with your chosen scheme. Log into the scheme portal, enter the property address, tenancy details and tenant information, then transfer the funds (custodial) or pay the insurance premium (insured).

Days 15–25 — Prepare the Prescribed Information. The scheme generates a protection certificate, but that alone does not satisfy your obligations. You also need to complete the statutory Prescribed Information form with every required field, including the deduction grounds from the tenancy agreement, and attach the scheme's official explanatory leaflet.

By Day 30 — Serve everything on the tenant. Hand-deliver against a signed receipt, or send by recorded delivery. If a parent, employer or local authority paid the deposit, serve them too. Keep proof of service.

Common Mistakes That Create Liability

The most expensive mistake is confusing the deposit protection certificate with the Prescribed Information. Downloading a certificate from DPS or TDS is not the same as serving the full statutory notice. Courts routinely award penalties where a landlord protected the deposit on time but never served the Prescribed Information.

Other frequent errors:

• Counting the 30 days from the tenancy start date rather than the date the money arrived
• Missing a third-party payer (a guarantor parent, for example)
• Serving the Prescribed Information by email without the tenancy agreement explicitly allowing electronic service
• Failing to update and re-serve when a joint tenant changes

What Happens If You Miss the Deadline

Under Section 214 of the Housing Act 2004, a court must order you to return the deposit or protect it immediately, and pay the tenant between one and three times the deposit value. For a £1,500 deposit, that's between £1,500 and £4,500 in penalties on top of returning the principal.

Since the abolition of Section 21, non-compliance also blocks a possession order under Section 8 — except on Grounds 7A and 14 — until the breach is cured.

Keep It Current Through the Tenancy

Deposit protection is not a one-off task. A rent increase under Section 13 may raise the deposit cap, and if you request a top-up, the new funds need protecting and fresh Prescribed Information served within 30 days. A change of joint tenant requires updated scheme records and new service. Switching from a letting agent to self-management means verifying every piece of paperwork the agent should have served.
