I've found Green Network to be efficient and fair. If our bills turn out to be more expensive than first thought it's because our usage is higher. I work in the sector and after pricing the unit and daily standing charges for residential supplies I've found Green Network to be the best priced.
Customers - never be fooled by the monthly DD charge. You are paying for what you use, at a unit cost. That's what you need to look for not the monthly standing charge. Also keep sending in your meter readings and you won't get a catch-up bill because your bills were under-estimated. Compare Green Network unit rates for both gas and electricity and you'll find they cost much less than other suppliers and in addition they are Green.
