Gas Safety Regulation 2001

This section applies to gasfitting work if—

in the course of the work a gas appliance (the original appliance) is disconnected from a consumer piping system; and

the original appliance has not been reconnected; and

another gas appliance has not been connected in place of the original appliance.

This section applies to gasfitting work whether or not other gasfitting work is performed on the same consumer piping system.

As soon as possible after the gasfitting work is performed and before leaving the premises where, at the time of the disconnection, the original appliance was located, the responsible gasfitter must—

cap the system outlet for the appliance; and

test the system and ensure that there are no leaks.
