What happens
The fire service visits your home, gives fire safety advice tailored to you and discusses any risks they find. They also talk through what to do in an emergency. They need your consent to visit, and afterwards they can refer you on for other support if you need it.
If you need them, they can fit smoke alarms and carbon monoxide alarms for you.
If your home is rented, or is a house in multiple occupation, they cannot fit or replace alarms, as that is the landlord's responsibility. They can still visit and give advice, and contact your landlord if needed.
