Ofgem have published their 'price cap' today here
Basically depending a bit on region the max that suppliers can charge for leccy is about 53 p unit in the midlands and more like 57p in Mersyside, and the south east.
Gas will be 15.5-16p per kwhr again varying a bit by region.
I think things like solar Panel setups that last year would have needed a decade to pay for itself will now be looking a lot more attractive.
