Our Mapping Service

What area do we cover?

Whilst we have a UK-wide operating licence, our network currently covers Wales and the South West of England. If you're based outside of our area, please visit the Ofgem website to find out who your local gas network owner is.

Below you can access the maps of our network of pipes through a postcode checker tool. This will enable you to search our network and produce scaled plans. The maps of pipes provide a guide for location, but in any circumstances its best to report your planned works to Wales & West Utilities' Plant Protection team to ensure your safety.
