Every house that has a gas supply has to be identified and
visited. If N/A, revisited etc. If people are away, lots are, or the
property vacant then it has to be isolated, and if the meter is not external
then the service has to be cut off by excavating it first. The reason for
all of this is that some people still have gas appliances with non-cut off
pilot lights. If pressure was restored to such appliances, uncontrolled gas
would fill the property. Missing even a single property is not allowed.

"non-cut off pilot lights" - that sounds very dangerous.
Yet another reason why I won't have gas anywhere near the house.
There have been three emergencies with my neighbours' gas supplies.
I have an amusing video of workmen trying to seal a broken pipe.

The amount that comes out of an unlit pilot light doesn't pose
much risk of anything.
