Nothing to do with 'green' lads, it's companies taking the piss and hiding behind a fallacy when it comes to the boiler's.
On the other point, solar is cheaper, but until the Gov disassociate solar elec from gas prices, companies will again keep swimming in the cash and you all know where I stand on this topic, but I would never pay more for 'green energy' as it's public relations fraud in effect.
I also wouldn't get too upset about the new £16 quid price cap rise Ofgem are talking about as it pertains to 'those in debt'. That will become a trade off for the removal or significant reduction in standing charges that everyone pays.
Smoke and mirrors.
