HMO Amenity Standards in England: Bathrooms, Kitchens, and Ratios

Room sizes get the headlines, but amenity ratios are where HMO licence conditions bite hardest in practice. A property can have perfectly sized bedrooms and still fail if the number of bathrooms, toilets, or kitchen facilities doesn't match the occupancy — and the ratios are set locally, not nationally, which means the requirements change from one council to the next.

Standard Amenity Ratios

While there is no single national schedule of required ratios (councils set their own under local amenity standards), the following table reflects the baseline that most councils in England apply:

"Separate WC" means a toilet in its own room, not inside a bathroom. Some councils insist on this from five occupants; others only at higher numbers. Check your council's specific standard.

Bathroom and Shower Requirements

Each bathroom must contain a bath or shower, a wash hand basin, and adequate ventilation (either a window or a mechanical extractor fan). Hot and cold running water, slip-resistant flooring, and a lock on the door are standard across most licensing conditions.

En-suite bathrooms count toward the ratio — a bedroom with its own shower room means one fewer shared facility is needed. But the en-suite must meet the same standards as a communal bathroom: ventilation, hot water, and adequate drainage.

Councils increasingly expect thermostatic mixing valves (TMVs) on baths and showers in HMOs to prevent scalding — particularly in properties housing vulnerable tenants or where the hot water system operates above 60°C.

Kitchen Standards

Shared kitchens in HMOs must provide each occupant with adequate cooking, washing, and food storage facilities. The practical requirements include:

• Cooker or hob: One four-ring cooker with oven for every five occupants is the common baseline. A microwave oven alone doesn't substitute for a cooker.
• Sink with drainer: One sink per five occupants, with hot and cold running water. Some councils accept a dishwasher in place of a second sink for 6–7 occupants.
• Worktop space: At least 500mm of worktop per occupant is typical, with a minimum of 2 metres total.
• Refrigerator: 0.1 m³ of fridge space per occupant — roughly equivalent to a standard under-counter fridge for every five people.
• Food storage: Individual lockable cupboards or dedicated shelving per occupant in larger HMOs.
• Waste bins: Adequate capacity for the number of occupants, with external bins for waste and recycling.

If tenants don't have access to a communal kitchen (some bedsit-style HMOs have individual cooking facilities in each room), each unit must include the full complement of cooking and washing equipment.

How Standards Appear on the Licence

Amenity standards get written into the HMO licence as conditions. A typical licence condition might read: "The licence holder shall ensure that bathroom and kitchen facilities are maintained to the standard set out in the Council's HMO Amenity Standards document and are available for the use of the occupants at all times."

Breaching a licence condition is an offence under s.72(3) of the Housing Act 2004, carrying civil penalties of up to £40,000. If a shared kitchen sink breaks and you don't replace it within a reasonable timeframe, or if you remove a cooker from a kitchen that needs two, you're in breach.

The HMO licensing guide details the amenity ratios alongside the full set of licence conditions, so you can audit your property against the standards before submitting the application.
