Houses in Multiple Occupation (HMOs) come with significantly more compliance obligations than standard single-let properties. Missing even one requirement can result in your HMO licence being revoked, fines of up to £30,000, and in extreme cases, criminal prosecution. This complete guide covers every certificate and safety requirement for HMO in 2025.
Contents
1. Gas Safety Certificate — Annual
HMOs with gas appliances require an annual Gas Safety Certificate (CP12) — the same as standard rental properties. However, HMOs often have more gas appliances (multiple hobs, shared boiler systems) which increases the inspection time and cost.
- Provide a copy of the CP12 to each tenant within 28 days of inspection
- Display a copy in a common area for tenant reference
- Retain records for 2 years
2. EICR — Every 5 Years
The EICR requirement for HMOs is the same as standard rentals — every 5 years or at change of tenancy if sooner. However, HMO licences sometimes specify a shorter period (e.g. every 3 years) — check your licence conditions.
HMO EICRs may take longer due to shared electrical systems, more circuits, and communal areas, which can affect the price.
3. EPC — Minimum E Rating
HMOs require an EPC with a minimum E rating, the same as standard rentals. The EPC must be provided to all tenants and is valid for 10 years. Note: some councils assess HMOs for a property-wide EPC rather than per-room EPCs.
4. PAT Testing — Annual (Effectively Mandatory)
While there is no single law specifically requiring PAT testing in HMOs, most local council HMO licence conditions require it. The PAT testing of all portable electrical appliances supplied by the should be carried out annually.
Shared appliances in HMOs (fridges, microwaves, washing machines, TVs in communal areas) are particularly important to keep tested, as they are used by multiple tenants and wear out faster.
5. Fire Safety Requirements
HMOs have strict fire safety requirements under the Regulatory Reform (Fire Safety) Order 2005 and Housing Health and Safety Rating System (HHSRS):
- Fire Risk Assessment: Documented assessment by a competent person — must be reviewed annually
- Fire detection: Interlinked smoke alarms in each room and hallway; heat detectors in kitchen
- Carbon monoxide alarms: In all rooms with combustion appliances (since October 2022)
- Fire doors: Self-closing FD30 fire doors on all rooms leading to escape routes
- Emergency lighting: In corridors and stairways if applicable
- Fire extinguisher: In kitchen area
- Fire escape routes: Must be kept clear at all times
6. HMO Licence Requirements
Mandatory HMO licensing applies to properties with 5 or more people from 2 or more households. Many councils also operate additional licensing schemes covering smaller HMOs — check your local council's website.
HMO licence applications typically require evidence of:
- Valid Gas Safety Certificate
- Valid EICR
- Valid EPC
- Fire risk assessment
- PAT test records
- Proof of adequate room sizes and facilities
