Just a couple of things on your energy switch.
I did some comparisons and for some reason I could not find Bulb in any of the searches. They are one of the top 5 green energy supplies I believe and also you get £50 back for a successful recommendation. And their smart meter integration to their web site is quite good. queue second point. :-).
On the smart meter front it’s all very well switching but can you include if the switch would allow you to carry on using your smart meter. And I mean fully as in the meter readings will be picked up by the energy company on a daily basis and applied it the account for viewing. I know this may only apply to SMETS 2 meters but it may be a deal breaker for some.
