Your Section 21 notice needs checking: original tenancy start date can be proved
That improves confidence on the timing analysis, especially around the first four months and the renewal chain.
Legal basis for this outcome
This outcome is based on Housing Act 1988, section 21. Because the original tenancy start date can be proved, the point needs checking alongside the dates, documents, and other Section 21 requirements before you can treat the notice as safe or defective.
Legal conclusion: Possible issue identified. Confidence: Medium confidence.
How the checker uses this point: A provable original start date lets the checker test the timing rules more cleanly.
Why it matters legally: The original tenancy start date still matters to first-four-month analysis and to the overall transition timeline. Missing start-date evidence lowers confidence.
What could change the answer: A different service date, possession date, or claim issue date could move the notice back inside or outside the transition window. A re-served notice or later corrected notice can change which timeline applies.
What to gather
- The Section 21 notice itself, including the date served and the possession date written in it.
- The tenancy agreement, plus any earlier renewal or replacement tenancy documents.
- Any court claim form, issue date, or possession paperwork if proceedings have started.
What to do next
- Keep the notice and supporting documents together so you can test the full chain, not just this point.
- Run the full Section 21 checker to see whether this combines with other issues.
- If the landlord starts court action, keep the evidence ready for a defence or advice appointment.

- What evidence usually matters most?
- The Section 21 notice itself, including the date served and the possession date written in it. The tenancy agreement, plus any earlier renewal or replacement tenancy documents. Any court claim form, issue date, or possession paperwork if proceedings have started.
