Your Section 21 notice may be invalid: five or more people from two or more households shared the property and no HMO licence was in place
Direct answer
That usually creates a strong issue if the occupancy facts are right. Mandatory HMO licensing can block reliance on a legacy Section 21 notice.
Legal basis for this outcome
This outcome is based on Housing Act 2004, section 75 and Housing Act 2004 licensing restrictions. Because five or more people from two or more households shared the property and no HMO licence was in place, 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: Medium confidence.
How the checker uses this point: The checker uses the occupancy pattern to catch licensing problems even where the tenant originally answered that no licence was needed.
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
- Keep the notice, tenancy agreement, and every supporting document together in date order.

- 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.
