Unprotected deposits: penalties and how to fix it
Late or missing protection exposes a landlord to a claim of up to three times the deposit, repeated for each tenancy renewal.
4 min read · Updated 21 August 2026
Overview
A deposit taken for an assured tenancy must be protected in an authorised scheme within thirty days of receipt, and prescribed information must be given to the tenant and anyone who paid on their behalf in the same window. Missing either step allows the tenant to apply to court for compensation of between one and three times the deposit, in addition to the return of the deposit itself. The claim can be brought during the tenancy or after it ends.
Why it matters
This is the most expensive routine mistake in residential letting, and it is entirely avoidable. It also blocks certain possession routes while the breach continues.
Legal requirements
- Protection and prescribed information are both required within thirty days of receipt.
- Compensation ranges from one to three times the deposit at the court's discretion.
- A separate award can arise for each tenancy where the failure was repeated.
- Returning the deposit late does not remove the right to claim compensation.
Common mistakes
- Protecting the deposit but never serving the prescribed information.
- Failing to reissue prescribed information after a change of landlord or scheme.
- Treating a holding deposit converted to a tenancy deposit as if the clock started later.
- Assuming a deposit paid by a parent does not need prescribed information served on them.
Practical guidance
- Protect on the day the money arrives and serve the prescribed information the same week.
- Keep the scheme certificate and a dated proof of service in the tenancy file.
- Audit older tenancies now and correct any gap before it becomes a claim.
- Reissue prescribed information whenever the landlord, agent or scheme changes.
Fixing a historic failure
If you find an unprotected deposit, protect it immediately and serve the prescribed information. That does not extinguish an existing claim but it stops the breach continuing and courts take remedial action into account when setting the multiplier. In some situations returning the deposit in full is the cleaner commercial answer, particularly where the tenancy is ending and the deductions you had in mind are modest. Take advice before deciding, because the choice affects any possession plan too.
Prescribed information in practice
The prescribed information includes the scheme details, the deposit amount, the property address, the landlord and tenant contact details, the circumstances in which deductions may be made and details of anyone who paid the deposit on the tenant's behalf. Serve it as a signed document, keep a copy and record how and when it was delivered. Many claims succeed not because the deposit was unprotected but because the landlord cannot prove the information was ever given.
Frequently asked questions
Does the thirty day period include weekends?
Yes, it is thirty calendar days from receipt of the deposit, not working days.
Do I need to reprotect when a fixed term becomes periodic?
Protection generally continues, but scheme rules and prescribed information duties can differ, so check with your scheme and reissue information if the tenancy details change.
How long does a tenant have to bring a claim?
A claim can be brought during the tenancy and for a period after it ends, commonly treated as six years, so old failures do not simply expire.
