Deposit not protected and Section 21
Direct answer
If a tenancy deposit was not protected, the landlord may be blocked from relying on a legacy Section 21 notice unless the deposit issue was properly remedied before service. The tenant may also have a separate deposit penalty claim.
A landlord or agent may use DPS, MyDeposits, or TDS. Search all three using the tenancy address, tenant name, and deposit date, then save screenshots of matches or no-match results.
A protected deposit can still have a prescribed-information problem. An unprotected deposit is even more serious, but the Section 21 consequence depends on whether the deposit was returned, when the notice was served, and whether any claim was resolved.
The deposit penalty route and the Section 21 defence overlap but are not identical. A tenant can need both timelines: one for whether the notice is usable, and one for whether compensation may be claimed.

Common questions
- Does an unprotected deposit make Section 21 invalid?
- It can block a legacy Section 21 notice unless the landlord took legally effective steps before service. The exact answer depends on timing and remedy.
- Can the landlord protect the deposit late and still serve Section 21?
- Late protection may not be enough by itself. The landlord may need to return the deposit or resolve the claim before relying on Section 21.
- Can I claim compensation as well as defend Section 21?
- Possibly. Deposit penalty claims are separate from possession proceedings, so get advice on the best timing and evidence.
