Moving a gas meter

Hi how much do you charge to move a gas meter that is not on the wall but in a purpose built cupboard outside. We don’t yet have a smart meter so if we joined bulb and had one fitted could we get this done for free the meter is being moved less than a meter in length.

Best contact Bulb to discuss, for moving under a meter on the same wall I believe is £120.
They have started to install smarts but that would be in the existing location.
