New gas meter location and what I need to consider?

Under a garden the gas pipe service should be 375mm deep and under a footway 450mm. The trench should usually be 200-300mm wide. The trench should be safe and secure and not likely to cave in. The route of the trench should avoid obstructions such as drains or manhole covers and should be laid in straight lines. Inside the boundary is your responsibility to dig the ground and outside the boundary is the supplier responsible. In terms of the pipe the supplier will run the pipe from the boundary to the new meter location, which will be plastic. Once done you can back fill with normal soil and then use concrete to level off. Thank you Kam
