HMO Bathroom Requirements London
Most London boroughs expect at least one bathroom or WC for every five occupiers in a shared HMO — but wording and enforcement vary. This guide summarises registry data; your borough page has the authoritative standard.
The common 1:5 bathroom ratio
Most London licensing standards require at least one bathroom or WC for every five occupiers in a shared HMO — often expressed as “1 bathroom per 5 occupants”. This is a licensing amenity standard, not a single national statute applying identically in every context. Some boroughs enforce stricter ratios or additional washing facilities for larger properties.
Bathroom, shower room, or WC?
Council standards usually count a full bathroom (bath or shower, wash basin, WC) differently from a separate WC-only closet. En-suite facilities may not always reduce the shared bathroom requirement if communal space is limited — Bexley, for example, notes that en-suites do not automatically replace shared provision.

Frequently asked questions
Is one bathroom per five tenants always enough?
It is the most common London licensing threshold for shared HMOs, but larger properties or boroughs with stricter standards may require more. Count all occupiers who share facilities — not just tenants on the tenancy agreement — when calculating ratios.
Do en-suite bathrooms reduce the shared bathroom requirement?
Not automatically. Some boroughs treat en-suites as supplementary only. Check your borough standards page and confirm with the council if you are near the occupancy threshold.
Where do I find the exact bathroom rules for my property?
Open your borough’s HMO standards page on HMO KIT for amenity summaries, then follow the link to the council’s official standards PDF for the full wording.
