Unless things have changed very recently due to Covid restrictions the
local fire brigade go around pensioners houses installing fire alarms
for free when they have nothing better to do.

It is much more cost effective than having to put out a domestic fire.

Typically (for historical reasons) one over the TV in the living room
and one on the on upstairs landing. TV's haven't really caught fire much
since the valve era (when it was all too common).
and around here they have been supplying and fitting the Fire Angle
ones, whose 10 years batteries seem to fail after 1-2 years (I've had
4 like that).

Can anyone recommend an alternative?
