An HMO fire alarm is an interlinked system of smoke and heat detectors that sounds everywhere in the house when one detector triggers. In Trowbridge, a town of around 40,000 people in Wiltshire, the work is planned around the HMO rules for England and the council’s written HMO standards.

Which rules apply in Trowbridge?
Fire alarm and detection systems in Trowbridge must satisfy national law for England, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- Fire precautions follow a risk assessment; the LACORS Housing – Fire Safety guide (2008) is guidance, not law, but many councils base their standards on it.
- Mandatory HMO licence for 5 or more people in 2 or more households (since October 2018); councils can add additional licensing for smaller HMOs.
- BS 7671, the wiring standard, calls for arc fault detection devices in HMOs on new socket circuits, such as rewires and consumer unit changes.
- Smoke alarms on every storey with living accommodation and CO alarms by fixed combustion appliances (other than gas cookers) are required by law.
