Esferaluz Electric supply.

Hi to all.

Has anyone have a electric supply, or experience with esferaluz electric supply?

I have had a cost comparison through the Watiofy site, which has come up with the above electric company, with a cost reduction of 154 euro's, approx a 30% reduction on my yearly bill, which is with Endesa, based on actual electric use from my last Endesa bill.

Any comments or suggestions would be very helpful, as i don't wish to make the switch, only to find there will be issues.

Thanks. Tom.
