Protected vs Unprotected Tenancy Deposit — Consequences for Landlords and Tenants
What happens when a landlord protects a tenancy deposit in an authorised scheme compared to failing to protect it — including the s.21 bar and the penalty of 1–3x the deposit value.
Overview
The Housing Act 2004 (ss.212–215), as amended by the Localism Act 2011 and the Deregulation Act 2015, requires landlords in England and Wales to protect any deposit received under an AST in a government-authorised tenancy deposit scheme within 30 days of receipt, and to provide the tenant with 'prescribed information' about the protection within the same period. Failure has two significant consequences: the landlord cannot serve a valid section 21 notice, and the tenant can apply to the court for an order requiring protection plus a penalty of 1–3 times the deposit amount. From October 2015, the Deregulation Act 2015 introduced rules for legacy deposits (deposits received before 6 April 2007 that were never protected) requiring belated protection in order to use section 21.
Side-by-Side Comparison
Deposit Protected in Authorised Scheme
Pros
- Section 21 remains available — landlord can serve a valid no-fault possession notice
- No financial penalty — landlord retains the right to deduct legitimate costs from the deposit at the end of the tenancy
- Dispute resolution service available (free ADR) to resolve end-of-tenancy deposit disputes
- Demonstrates compliance — protects landlord's professional reputation and avoids court proceedings
Cons
- Administrative burden — must register within 30 days and serve prescribed information
- Scheme rules govern deductions — disputes decided by scheme adjudicator, not landlord
- Custodial schemes hold the money (tenant earns no interest in most schemes)
Best For
Every landlord receiving a deposit under an AST in England and Wales — compliance is mandatory and non-optional.
Deposit Not Protected (or Prescribed Information Not Served)
Pros
- No administrative steps taken at the outset — purely an omission, not a deliberate choice
Cons
- Section 21 notice invalid — landlord cannot serve a no-fault possession notice until the deposit is returned or protected and prescribed information served (HA 2004 s.215)
- Tenant can apply to court for an order requiring protection and a penalty of 1–3 times the deposit amount (HA 2004 s.214)
- Court has discretion to award up to 3x penalty for repeated or deliberate non-compliance
- Belated protection does not extinguish the tenant's existing penalty claim — only prevents future claims (Potts v Densley [2011])
Best For
There is no scenario in which failing to protect a deposit is advisable. The consequences are severe and easily avoided.
Key Differences
Our Recommendation
Protect every deposit within 30 days of receipt and serve the prescribed information immediately — the 30-day deadline is absolute. Use a calendar reminder or property management software to automate compliance. If you have inherited a tenancy with an unprotected deposit, take immediate advice: return the deposit (if the tenant agrees) or protect it and seek legal advice on whether a penalty claim has already accrued.
