Why has my gas bill doubled?

Hello

The cost of my gas has almost doubled for use from the past two months. As far as I am aware we have not used any more than usual. Any ideas why this might be lovely people?

Hi Allie, just read your post and funny you should say that because some good Spanish friends of mine have also experienced the same phenomina with their bill.Started out cheap but now, has almost doubled with no increase in usage.I think they are making a formal complaint to their provider.Who is yours as a matter of interest?
Regards David

Allie ,have you managed to glean any further information on why your gas account increased so dramatically.
