Hi all,
Following on from my thread regarding gas boiler sizing, I now have a
question about installing a gas meter box.

When I requested a quote for the provision of a new gas supply, I
requested a flush-fitting meter box, which is recessed into the wall,
so it doesn't protrude 25cm into the driveway. However, it requires a
cutout 366mm W * 532mm H * 160mm D. If a flush-fitting box is
specified, then this must be installed by the homeowner prior to the
pipe being laid.

I am not fussed about the height element, but in hindsight I am
concerned about cutting a hole 366mm wide in the brickwork, in case it
has any structural ramifications. The wall is a cavity wall, brick
construction both sides, with render on the outside.

Will I need to reinforce the hole over its span in any way? Or is this
impossible to tell without consulting a structural engineer?

Thanks
Luke

Additionally to the above you will need to make quite a large hole in
the inner wall. Gas meter boxes come complete with a tube that
isolates the gas pipe from the cavity. *This is to stop the cavity
filling up with gas in the event of a leak.
When you see a house levelled with a gas explosion, this is often the
cause.

I'll have to look out for them. Does it happen often?
