This has been available a long time and a free smoke alarm is given subject to availability! The promote this normally at fairs too!
LOL, a bit scary
I had my hfsc (house fire safety checks) done on Monday due to having to have it done as me and my fiance are about to start fostering. I thought it would be one guy in a car that turns up but nooooo I was wrong, I looked out the living room window as something caught my eye and a fire engine had pulled up outside our house and three firemen got out.. I called them Monday morning and they were here just after 2pm that day.
you need to ring your local fire service they should do free checks and sometimes fit smoke alarms. thanks op
