How to Protect a Tenancy Deposit UK: Step-by-Step

Protecting a tenant's deposit is one of the most fundamental legal obligations for UK landlords — and getting it wrong carries severe penalties. Fail to protect a deposit within 30 days of receiving it, and you face financial penalties of one to three times the deposit amount, lose the ability to serve notice to end the tenancy, and expose yourself to a county court claim that you will almost certainly lose.

Despite the clear legal requirements, deposit protection mistakes remain one of the most common compliance failures among private landlords. This step-by-step guide covers every aspect of the process: choosing a scheme, protecting the deposit, serving the prescribed information, handling disputes at the end of the tenancy, and avoiding the errors that cost landlords thousands.

The Legal Requirement

Under the Housing Act 2004 (as amended), any landlord who takes a deposit for an assured shorthold tenancy in England or Wales must protect it in a government-approved tenancy deposit scheme within 30 days of receiving it. The landlord must also serve the tenant with the scheme's prescribed information within the same 30-day period.

Step 1: Choose a Deposit Protection Scheme

There are three government-approved deposit protection schemes in England and Wales. Each offers two types of protection: custodial (free) and insured (paid).

Custodial vs Insured: Which to Choose?

With a custodial scheme, you transfer the deposit to the scheme and they hold it for the duration of the tenancy. At the end of the tenancy, you and the tenant agree how it should be returned, and the scheme releases it accordingly. This option is free.

With an insured scheme, you keep the deposit in your own bank account but pay the scheme an annual fee for insurance protection. If there is a dispute, the scheme can pay the tenant from the insurance policy and recover the funds from you. This gives you use of the money during the tenancy but costs £16–£28 per deposit per year.

Step 2: Protect the Deposit Within 30 Days

The 30-day clock starts from the day you receive the deposit — not from the tenancy start date. If the tenant pays the deposit on 1 March but the tenancy begins on 15 March, you must protect it by 31 March.

How to Protect (Custodial — DPS Example)

1. Create an account on the DPS website (depositprotection.com)
2. Log in and select 'Protect a Deposit'
3. Enter the property address, tenancy start date, and monthly rent
4. Enter the tenant's details (full name, email address, contact details)
5. Enter the deposit amount (maximum five weeks' rent for annual rent under £50,000)
6. Transfer the deposit to the DPS via bank transfer using the reference provided
7. Once the DPS confirms receipt, the deposit is protected
8. Download and serve the prescribed information on the tenant (see Step 3)

Step 3: Serve the Prescribed Information

Protecting the deposit is only half the requirement. You must also serve the tenant with the scheme's prescribed information within the same 30-day window. This is a separate legal obligation — protecting the deposit without serving the prescribed information still counts as non-compliance.

What the Prescribed Information Must Include

• The name and contact details of the deposit protection scheme
• The name and contact details of the landlord (or agent acting on their behalf)
• The name and contact details of the tenant
• The address of the rented property
• The amount of the deposit
• The purpose for which the deposit has been paid
• How to apply for the release of the deposit at the end of the tenancy
• Information about the dispute resolution service provided by the scheme
• The circumstances under which deductions may be made from the deposit

Each deposit protection scheme provides a standard prescribed information form that covers all requirements. Download this from the scheme's website, complete it, and provide a copy to the tenant. The tenant (and any relevant person, such as someone who paid the deposit on the tenant's behalf) should sign to acknowledge receipt.

Step 4: Deposit Cap Rules

The Tenant Fees Act 2019 caps the deposit a landlord can charge:

The calculation is: (monthly rent x 12) / 52 x 5 (or 6). Taking a deposit above the cap is a breach of the Tenant Fees Act and can result in a fine of up to £5,000 for a first offence or an unlimited fine and a banning order for repeat offences.

Step 5: During the Tenancy

Once the deposit is protected and prescribed information served, there are ongoing obligations during the tenancy:

• Re-protection on renewal: If the tenancy becomes a periodic tenancy (rolling month to month after the fixed term ends), the deposit protection continues automatically. You do not need to re-protect it.
• Rent increases: If you increase the rent, you cannot increase the deposit above the original protected amount for the same tenancy.
• Change of scheme: If you switch deposit schemes, you must protect the deposit in the new scheme within 30 days of it leaving the old scheme and serve new prescribed information.
• Change of landlord: If the property is sold, the new landlord must ensure the deposit is protected and serve fresh prescribed information within 30 days of the transfer.

Step 6: End of Tenancy — Returning the Deposit

At the end of the tenancy, you have 10 days (from agreement on the amount) to return the deposit or the agreed portion. The process should follow these steps:

1. Conduct a thorough check-out inspection, comparing the property's condition against the check-in inventory
2. Identify any damage beyond fair wear and tear, supported by photographs and the inventory report
3. Notify the tenant in writing of any proposed deductions, with evidence for each
4. Give the tenant the opportunity to respond and agree or dispute the deductions
5. If agreed, submit the release request to the deposit scheme with the agreed split
6. The scheme releases the funds — tenant's portion direct to the tenant, landlord's deductions to the landlord
7. If not agreed, either party can refer the dispute to the scheme's free dispute resolution service

Step 7: Handling Deposit Disputes

If you and the tenant cannot agree on deductions, all three deposit schemes offer a free alternative dispute resolution (ADR) service. An independent adjudicator reviews the evidence from both parties and makes a binding decision.

Winning Deposit Disputes

The adjudicator's decision depends almost entirely on the quality of evidence. Landlords who lose deposit disputes typically fail because they cannot prove the property's condition at check-in or the extent of damage at check-out.

• Comprehensive check-in inventory with dated, high-quality photographs of every room
• Check-out report conducted on or very close to the move-out date
• Side-by-side comparison photographs showing the condition change
• Invoices or quotes for cleaning, repairs, or replacements
• Evidence of fair wear and tear considered — deductions only for damage beyond reasonable use
• Clear tenancy agreement clauses covering the tenant's obligations

Common Deposit Protection Mistakes

These are the errors that most frequently land landlords in trouble:

• Missing the 30-day deadline: The most common mistake. Set a reminder the day you receive the deposit.
• Protecting but not serving prescribed information: Both steps are required. One without the other is non-compliant.
• Wrong amount protected: The protected amount must match the deposit received exactly.
• Not updating after landlord change: New landlords must re-serve prescribed information within 30 days.
• Deducting for fair wear and tear: You cannot deduct for reasonable deterioration from normal use. Worn carpet after a five-year tenancy is wear and tear, not damage.
• No check-in inventory: Without evidence of the property's condition at the start, you cannot prove damage at the end.
