Tenant Deposit Protection: Rules Every UK Landlord Must Follow

Deposit protection isn't optional. Since 6 April 2007, every landlord in England and Wales who takes a deposit under an Assured Shorthold Tenancy must protect it in a government-approved tenancy deposit scheme within 30 days of receiving it. Get this wrong, and you could face serious financial penalties and lose the ability to evict your tenant using a Section 21 notice.

Here's everything you need to know to stay compliant.

Why deposit protection exists

Before the Housing Act 2004 introduced compulsory deposit protection, disputes over deposits were one of the biggest sources of conflict between landlords and tenants. Landlords could — and some did — withhold deposits unreasonably, and tenants had little recourse beyond the county court.

The deposit protection schemes provide:

• Safe custody of the deposit (or insurance against its loss)
• A free dispute resolution service if landlord and tenant disagree about deductions at the end of the tenancy
• Transparency — tenants can check that their deposit is protected

The three government-approved schemes

There are three schemes authorised by the government:

1. Deposit Protection Service (DPS)

• Type: Custodial (free)
• The DPS holds the deposit for the duration of the tenancy
• No charge to the landlord or tenant
• Most popular scheme in England and Wales

2. MyDeposits

• Type: Insurance-based or custodial
• Landlord keeps the deposit but pays an annual fee for insurance cover
• Insurance-based fees depend on the deposit amount
• Also offers a free custodial option

3. Tenancy Deposit Scheme (TDS)

• Type: Insurance-based or custodial
• Similar to MyDeposits — landlord can choose between custodial (free) and insured (paid)
• Widely used by letting agents

Custodial vs insurance-based: what's the difference?

With a custodial scheme, you hand the deposit over to the scheme, which holds it until the tenancy ends. This is free.

With an insurance-based scheme, you keep the deposit in your own account but pay an annual premium. The scheme guarantees the deposit is available if there's a dispute. This costs money but gives you more control over the funds.

Most private landlords use the custodial DPS because it's free and straightforward.

The 30-day deadline

You must protect the deposit within 30 days of receiving it. This deadline is strict — there's no grace period and no exceptions. The 30 days start from when you (or your agent) receive the money, not from the tenancy start date.

If the deposit is paid in instalments, each instalment must be protected within 30 days of receipt.

Prescribed information: the other half of the obligation

Protecting the deposit is only half the job. Within the same 30-day window, you must also serve the tenant with prescribed information. This is a legal document that tells the tenant:

• The amount of the deposit
• The address of the rented property
• Which scheme the deposit is protected with (and the scheme's contact details)
• The landlord's name and contact details (or the agent's, if applicable)
• The purpose of the deposit
• How to apply to get the deposit back at the end of the tenancy
• What to do if there's a dispute
• The circumstances in which the landlord may keep some or all of the deposit

The prescribed information must be in writing, and the tenant must confirm receipt (ideally in writing). If you have joint tenants, you must serve the prescribed information on each tenant.

What happens if you don't protect the deposit?

The consequences of non-compliance are severe:

1. Financial penalty

A tenant can apply to the county court for an order requiring you to protect the deposit and pay compensation of between 1 and 3 times the deposit amount. The court has no discretion to award less than 1x — it's automatic if you fail to comply.

2. You cannot serve a Section 21 notice

If the deposit isn't protected (or the prescribed information hasn't been served), you cannot serve a valid Section 21 notice. This means you cannot use the standard "no-fault" eviction route, even if you have perfectly legitimate reasons for wanting the property back.

This restriction remains in force until either:

• You protect the deposit and serve the prescribed information, or
• You return the deposit to the tenant

3. The tenant doesn't need to have asked for the deposit back

A common misconception is that penalties only apply when the tenancy ends. In fact, a tenant can bring a claim for non-protection at any point during the tenancy.

Deposit caps under the Tenant Fees Act 2019

Since 1 June 2019, the Tenant Fees Act 2019 limits the amount you can take as a deposit:

• For tenancies where the annual rent is under £50,000: maximum deposit is 5 weeks' rent
• For tenancies where the annual rent is £50,000 or more: maximum deposit is 6 weeks' rent

If you take more than the legal maximum, you're in breach of the Tenant Fees Act, and the tenant can recover the excess through the county court.

How to calculate 5 weeks' rent

The formula is:

(Monthly rent x 12) / 52 x 5

For example, if the monthly rent is £1,000:

• Annual rent: £12,000
• Weekly rent: £230.77
• Maximum deposit: £1,153.85

Protecting a deposit: step by step

1. Choose a scheme — DPS (custodial) is the simplest for most private landlords
2. Register with the scheme (free for custodial)
3. Submit the deposit within 30 days of receiving it from the tenant
4. Serve the prescribed information on the tenant within the same 30-day period
5. Keep records — save confirmation emails, certificates, and proof of service
6. Confirm with the tenant — ask them to confirm receipt in writing

What about renewals and periodic tenancies?

If a fixed-term AST ends and becomes a statutory periodic tenancy (i.e. the tenant stays on without signing a new agreement), the original deposit protection remains valid. You do not need to re-protect the deposit.

However, if you grant a new fixed-term agreement (a renewal), some schemes require you to update the protection details. Check with your specific scheme.

If the deposit amount changes (e.g. because of a rent increase), the difference must also be protected within 30 days.

End of tenancy: returning the deposit

At the end of the tenancy:

1. Carry out a check-out inspection, comparing the property's condition against the original inventory
2. Agree deductions (if any) with the tenant — common deductions include cleaning, damage beyond fair wear and tear, and unpaid rent
3. Return the agreed amount within 10 days of both parties agreeing

If you can't agree, either party can raise a dispute through the deposit scheme's free alternative dispute resolution (ADR) service. The adjudicator's decision is binding.

Fair wear and tear

You cannot deduct for fair wear and tear. This means the normal deterioration that happens through everyday living — scuff marks on walls, worn carpet in high-traffic areas, slightly faded curtains. You can only deduct for damage that goes beyond what's reasonable given the length of the tenancy and the condition at check-in.

Deposit protection and your tenancy agreement

Your AST agreement should include clear clauses covering:

• The deposit amount
• Which scheme it will be protected with
• When the prescribed information will be served
• The circumstances under which deductions may be made
• Reference to the scheme's dispute resolution process

Getting this right in the agreement sets expectations from day one and reduces the likelihood of disputes later.
