No idea....and something I was wondering. Same pipe, different gas / electricity, I don't think so. However if it saves me £500+ per year and powers my stuff, I am not really sure I am bothered :)
I am considering moving to Bulb Energy. The main reason is potential cost savings, as it looks like I can save £500+ per year compared to my current provider.
They don't appear to be the cheapest, but customer service ratings look good......and I can also bang on about the benefits of using...
