There are many possible scenarios with a gas leak. We check for gas pressure and if we detect a drop in pressure between the meter and the appliance, this typically indicates a leak somewhere in the gas line. Given that the lines are underground, it is often not possible to determine the location of the leak - for this reason, safety legislation requires the attending plumber to shut off the gas entirely (or to the relevant appliance), in which case we will recommend a repair or replacement immediately.
