It might not seem to be that important in the grand scheme of things but your Gas meter box really is something that you should give some consideration to. As it is placed on the outside of the house it’s one of the first things that people will see when they look at it. It really isn’t the best impression when the see door hanging off or the innards exposed.
The Gas Meter box is not just something that is a part of the aesthetic of the house it also serves an important purpose in protecting the recording devices inside. If there are any issues with the measurements because of the elements you will soon see that in your bill. The devices are protected and sealed but even so an additional layer of protection to the electronics is always welcome. You still need to try and protect the measurement device from strong sunlight, frost snow and extremes of cold. It will also make it easier to read it when you need to report the figures to the provider.
So make sure that you look at having the box replaced if it is damaged in any way, not only will it look much better it will stop the neighbours from figuring out how much gas you actually use.
