HMO electrical requirements explained
Houses in multiple occupation (HMOs) face stricter electrical and fire-safety rules than a standard let: a satisfactory EICR (often required more frequently under licensing), an interlinked fire detection system sized to the property, emergency lighting where the fire risk assessment calls for it, and PAT testing of any appliances you supply. The exact requirements depend on the property and your council's licensing scheme.
EICR and electrical safety
Like any rented home, an HMO needs a satisfactory EICR — but HMO and selective licensing schemes often require it more frequently than the standard five years, and the council may ask to see it as a licence condition. It's worth confirming the interval your specific scheme sets.
Fire detection
HMOs need a fire detection and alarm system appropriate to the building — commonly a mains-powered, interlinked system so that a detector triggering in one part alerts the whole house. The exact grade and coverage come from a fire risk assessment, which is the document that legally drives what you install.
Emergency lighting and appliances
Depending on the layout and the fire risk assessment, an HMO may also need emergency lighting on escape routes. And any electrical appliances you supply (cookers, kettles, microwaves) should be PAT tested as part of keeping the let safe.
How often does an HMO need an EICR?
At least every five years like any rented home, but many HMO and selective licensing schemes require shorter intervals. Check your council's licence conditions — they take precedence.
What fire alarm system does my HMO need?
It depends on the size and layout of the property and your fire risk assessment. Smaller HMOs commonly use a mains-interlinked system; larger or higher-risk ones need more. The fire risk assessment specifies it.
Who decides exactly what I need?
Your council's licensing scheme and a fire risk assessment set the legal requirements. We can survey the property and quote a compliant package once those are clear.
