More information is needed: I do not know whether the property crossed the mandatory HMO threshold
Direct answer
More information is needed. Count the occupants and the number of separate households before relying on this point either way.
Legal basis for this outcome
This outcome is based on Housing Act 2004, section 75 and Housing Act 2004 licensing restrictions. Because I do not know whether the property crossed the mandatory HMO threshold, 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 downgrades confidence where the occupancy pattern is unknown because that can change whether a licence was required at all.
Why it matters legally: A property with five or more occupiers from two or more households may need a mandatory HMO licence. That can matter even where the tenant first thought no licence was required.
What could change the answer: The answer can change if the local authority confirms no licence was required, or confirms that a licence application was already pending. The occupancy pattern and local licensing designation both matter, so local authority records can shift the result.
What to gather
- Local authority licensing records, HMO register entries, or the landlord's licence number.
- Occupancy details showing how many people and households shared the property.
- Any licence application acknowledgement or local authority correspondence.
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.

- What evidence usually matters most?
- Local authority licensing records, HMO register entries, or the landlord's licence number. Occupancy details showing how many people and households shared the property. Any licence application acknowledgement or local authority correspondence.
