Hi all,

A friend of mine is a landlord of three flats. Upon a recent British
Gas inspection, he was told that all was okay, but it would be advisable
for each flat to have a gas stopcock inside (all three are currently
together downstairs). He's a little green on these issues so I said I'd
ask here. Is this a good idea or are British Gas trying to waste his
money (I don't know if they'd do the work themselves)? How much should
this type of thing cost?
