In short: An HMO fire alarm is an interlinked system of smoke and heat detectors that sounds everywhere in the house when one detector triggers. In Hertfordshire we survey first, price each item separately and hand over the certificates and photos a council asks for.

Which rules apply in Hertfordshire?
- 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.
- Electrical installations must be inspected and tested at least every 5 years; remedial work is due within 28 days, or sooner if the report says so.
- Smoke alarms on every storey with living accommodation and CO alarms by fixed combustion appliances (other than gas cookers) are required by law.
- The Fire Safety Order 2005 applies to the common parts of HMOs, enforced by the fire and rescue authority.
Councils in England can add additional licensing and Article 4 directions on top of the national rules. Check the council’s website for the exact address before you buy or start work.
