An HMO fire alarm is an interlinked system of smoke and heat detectors that sounds everywhere in the house when one detector triggers. Landlords in Castlereagh (BT5 and BT6) usually come to us with a council letter, a fire risk assessment or a house they have just bought. We price from whichever you have.

- Licences usually last 5 years, and landlords must also register with the NI landlord registration scheme.
