Expensive gas bills with Bulb - what could have happened?

I don't think the OP is blaming Bulb?  However, the moment Landis & Gyr 310p was mentioned the meter does become prime suspect.  But unless it's still doing it today and without n years of consumption data from a previous meter, it's going to be difficult to prove anything.

Though not specifically a problem created by bulb the OP has complained and been fobbed off as is standard by energy suppliers who are supposed to be the experts! I was told numerous times my meter was fine by the energy company (even at 64m3 used in 48hrs !) before having to go to the ombudsman

From the OP:

"Especially since they have been in the news recently for overcharging customers."

This has turned out to be a red herring at least.
