Shale in my gas supply

My boiler won’t stay on apparently because of shale in my gas supply. How do I address this problem as Worcester Bosch will only come out to boiler problems, not ones relating to supply issues?

Bulb only buy gas from wholesale. Contact your DNO first. A handy map can be found here of who yours is

Ah wait this is gas, but there is similar distribution network I’d imagine. I don’t have that graphic handy

Thanks for the advice. I’ll check it out

Here is a quick region breakdown to save you the legwork for gas.

Thanks very much. I’m in the W Midlands so will get in touch with Cadent Gas first thing on Monday.
