More information is needed: written complaint date cannot be proved
More information is needed. A missing complaint date can make the retaliatory-eviction sequence much harder to prove cleanly.
Legal basis for this outcome
This outcome is based on Deregulation Act 2015, section 33. Because the written complaint date cannot be proved, the checker cannot give a reliable answer until the missing date, document, or fact is confirmed.
Legal conclusion: More information needed. Confidence: Low confidence.
How the checker uses this point: The checker lowers confidence where the complaint exists but the date cannot be pinned down from evidence.
Why it matters legally: The complaint date matters because the retaliatory-eviction chain is highly sequence-sensitive. It can affect how the landlord's 14-day response window is judged.
What could change the answer: The answer can change if the landlord's response was timely and adequate, if the council did not serve a qualifying notice, or if a notice was later quashed. A missing complaint date, email chain, or council notice often turns a strong point into an evidence problem instead of a clear bar.
What to gather
- Your written complaint to the landlord, with the date sent and the landlord's reply if any.
- Council environmental health emails, case references, inspection notes, or notice documents.
- The Section 21 notice date compared with the complaint and council-enforcement timeline.
What to do next
- Find the missing document or date evidence before relying on this point either way.
- Run the full Section 21 checker and mark any unknown answers carefully so the evidence gaps are visible.
- If court deadlines are close, get advice even before every document is complete.
