An HMO fire alarm is an interlinked system of smoke and heat detectors that sounds everywhere in the house when one detector triggers. For a house in Portsmouth we start with a measured survey, check the council’s written HMO standards for the number of sharers, and then price each item separately. With students as well as working sharers renting in Portsmouth, we plan bigger jobs for the gap between academic-year tenancies where we can.
