i have a semi concealed brown gas meter box which has recently been damaged. i believe the repair of the meter box is the house owners responsibility so looking at ways to repair. i have an upcoming smart meter installation so wondering if i was to purchase a new box and get the smart meter installer to fit. however, looking at he the inlet valve i'm not sure if this is possible as there's no way to get the box to be removed and install over the existing valve. are there other valves on the incoming supply that can isolate the gas? just checking as i don't want to waste £80 on a new box and there's no way to fit it.
