Hi,
I have used Ebico in the past for both gas and elecetric. They're admin work is done by southern electric. Good service providers!
As to price increase, this is rare with this company but does happen when the market goes wild..... BUT if your getting a good price now with Ebico then swtich, dont wait around.....
If they increase their price then you can inform them you are not happy with the changes and they will allow you to switch as usual and you would continue paying the present rates until you switched to another supplier.
PS. this is the same with all suppliers, so, if you ever find a good deal, go for it!!!
