Moving a gas meter, costs?

[megaphone]

Meter is on an outside porch wall, I want it on the main wall as the porch is going. About 1m. incoming pipe will need to be dug out and extended I suspect. Anyone had this done? Are there independent companies around who are allowed to do it? Or is it just National Grid or the like? Keep being told it will cost £800-£1k!!

Thanks for the replies, not really what I wanted to hear! Is it just National Grid who do this? Do they have a monopoly?

I've done the online calculator and its coming back with £1500! I may try and speak to a human. If it costs more than £500, it can stay where it is, I'll do something with the wall, make it into a flower box or similar.
