Your Section 21 notice may be invalid: deposit was not protected
Usually no. An unprotected deposit is a strong Section 21 problem unless the breach was later cured in a legally effective way before service.
Legal basis for this outcome
This outcome is based on Housing Act 2004, section 215. Because the deposit was not protected, the checker treats this as a likely Section 21 defect unless the landlord can prove the requirement was met or legally cured before the notice was served.
Legal conclusion: Strong issue identified. Confidence: High confidence.
How the checker uses this point: The checker treats deposit protection as one of the strongest legacy Section 21 bars when a deposit was taken.
Why it matters legally: Where a deposit was taken, failure to protect it properly can bar reliance on Section 21 under the Housing Act 2004.
What could change the answer: The answer can change if the landlord can prove an earlier protection date, an earlier service date for prescribed information, or a proper return of the deposit before service. If the paperwork is incomplete, the underlying scheme record often changes the analysis.

- What evidence usually matters most?
- Deposit protection certificate, scheme confirmation, or screenshots from DPS, MyDeposits, or TDS. The date the deposit was paid and the date it was protected or returned. The prescribed information pack and any email or letter that served it.
