An elderly person I know has recently had a stroke and will shortly
return home. Mentioned as a good idea was a method to isolate the
gas cooker if she is left alone for a while - reason being in case she
forgets to turn it off - and to get in touch with a Corgi registered
plumber to do the job. Anyone any idea of such a device and just what
it does? Never heard of the like myself, so wondering as to what it
is and the likely cost.

Are you worried about gas being turned on but not lit? Thought most modern
types won't allow this?

You would need to be able to let gas by via the unlit burners in order to
purge air from the gas supply pipe.
