Fire safety for other residential properties
If your property is not an HMO, there are laws to comply with and you do have a general duty to keep the property habitable (including an obligation to arrange for any necessary repairs to be carried out).
By law, you must install:
carbon monoxide detectors (where solid fuel appliances are in use)
If the local housing authority consider that fire hazards in the property could endanger your tenants health or cause a serious nuisance to neighbours or the general public, their housing team may wish to inspect the property and can order landlords to put the problems right.
