Around here the fire service will fit free smoke alarms for vulnerable
people. Even special ones for the deaf and ones where the battery is in
a box on the wall so you can change it without steps.

The elderly couple that live next door to me make use of that service. A fire engine turned up the other week to replace their smoke alarms. Seemed a bit OTT.

I had told the couple that I would do it for them but I guess they didnt want to bother me.
