Sorry for the late question, I have been away for a few days, but what
would happen in this country if a sizeable area actually lost its gas
supply and needed to be reconnected?

In my house the combi should be fine. The sensor will detect no gas and
close the valve off. I am sure my cooker would fill the house up with
gas if it lost its gas supply and then was reconnected.

That happened with us recently when a gas main was accidentally cut.
Before the supply could be restored, every house ahd to have its gas
supply turned off. Fine if you were in the house when they called. If
not, they dug up your incoming supply and physically cut it off.

If someone chops through a service main with a JCB, it's much cheaper to
let the gas vent and monitor the pressure than to cut the gas off.
