Around Montmorillon

I have two questions
1 does anyone else have town gas central heating ? We are with Gaz de France and their prices have gone up by 51%. Can anyone recommend an alternative supplier

2 our electric supplier is Soregies are they part of EDF ?

I can't help with gas but I can confirm that Soregies are not part of EDF. It is, you might say, a 'local supplier for local people', being founded in the Vienne in 1925...
