Peterborough HMO Overcrowding Rules and Maximum Occupancy

How Peterborough Sets Maximum Occupancy

Every HMO licence issued in Peterborough specifies a maximum number of occupants. That limit is not arbitrary — it is calculated from the usable floor area of each sleeping room, the amenity provision (kitchens and bathrooms), and whether communal living space is available.

The statutory minimum room sizes for sleeping accommodation in licensed HMOs come from Schedule 4 of the Housing Act 2004 and the Licensing of Houses in Multiple Occupation (Mandatory Conditions) (England) Regulations 2018 (SI 2018/616):

• Single room (one person aged 10 or over): minimum 6.51 m²
• Double room (two people aged 10 or over): minimum 10.22 m²
• Child's room (one person under 10): minimum 4.64 m²

Any part of a room where the ceiling height is less than 1.5 metres cannot be counted toward the minimum floor area. This matters in attic conversions, rooms under stairs, and properties with sloping ceilings — the usable area is often significantly smaller than the total floor area.

The Communal Lounge Factor

Peterborough City Council applies a secondary standard that many landlords miss. If the property provides a separate communal living room (a lounge or sitting room that is not used as a bedroom), the bedroom minimums above apply. But if there is no communal lounge — if the only shared space is the kitchen — the council may apply higher bedroom minimums, because the room must serve as both sleeping and living space.

Under the local amenity standards, a single bedroom without access to a communal lounge may need to measure at least 10 m² rather than 6.51 m². This single difference can reduce the maximum occupancy of a property by one or two people, directly affecting your rental yield.

Measure carefully, and measure before you apply. The council will inspect the property during the licence term, and if room sizes do not match what was declared in the application, you face a compliance notice and potential enforcement action.

Kitchen and Bathroom Ratios

Maximum occupancy is also constrained by shared amenity provision:

• Kitchen facilities: For up to five occupants, the kitchen must have at least one full oven and hob, one sink with a draining board, hot and cold water, a fridge-freezer of adequate capacity, and sufficient dry food storage. Above five occupants, additional cooking and washing facilities are required at prescribed ratios.
• Bathroom facilities: A minimum of one bathroom with WC and wash hand basin for every five occupants.

If the kitchen can only serve five people but the bedrooms could accommodate seven, the licence will be capped at five. The lowest limit across all three factors — room sizes, kitchen capacity, and bathroom provision — determines the maximum occupancy.

What Happens If You Exceed the Licence Limit

Exceeding the maximum occupancy stated on your licence is a criminal offence under Section 72(3) of the Housing Act 2004. Peterborough City Council can issue a civil penalty of up to £40,000 per offence, and the breach can lead to licence revocation.

Beyond the direct penalty, an overcrowded property exposes tenants to increased fire risk, inadequate sanitation, and poor living conditions. If those conditions create Category 1 hazards under the Housing Health and Safety Rating System (HHSRS), the council can serve improvement notices or prohibition orders requiring you to reduce occupancy immediately.

Tenants in an overcrowded HMO may also have grounds to apply for a Rent Repayment Order, recovering up to 24 months of rent.

Practical Steps to Stay Compliant

1. Measure every sleeping room accurately — include only the area where the ceiling is at least 1.5 metres high
2. Check whether you have a communal lounge — if not, expect the council to apply the higher bedroom minimums
3. Count amenities — make sure your kitchen and bathroom provision supports the number of tenants you want to house
4. Declare the correct occupancy in your application — overstating capacity to maximise rent leads to enforcement action at the inspection stage
5. Keep records — if occupancy changes during the licence term, apply for a licence variation rather than simply adding tenants

Our Peterborough Landlord Licensing Guide includes a room measurement worksheet and amenity ratio table that lets you calculate your property's maximum licensed occupancy before you start the Home Safe portal application.

Frequently Asked Questions

Can the council reduce my licensed occupancy after issuing the licence?

Yes. If a property inspection reveals that rooms are smaller than declared, or that amenity provision is insufficient, the council can vary the licence to reduce the maximum occupancy.

Does the 6.51 m² minimum apply to selective licences too?

The statutory room size conditions in SI 2018/616 are mandatory conditions for HMO licences specifically. Selective licences do not carry the same mandatory room size conditions, but the council can still enforce housing standards under the HHSRS if rooms are dangerously small.

My attic room is 8 m² total but part of it has a sloped ceiling below 1.5 metres — what counts?

Only the floor area where the ceiling is at least 1.5 metres high. If 2 m² of the room falls below that threshold, the usable area is 6 m² — which does not meet the 6.51 m² minimum for a single adult bedroom.
