@Pete, out of interest, which suppliers are you talking about which are offering significantly cheaper fixed price plans?
There are always going to be suppliers that offer cheaper plans, but I’d be very wary of their customer service, millions of tarrifs, and hidden charges. They’ve all got to make money somehow; at least Bulb are honest about it all.
When I joined Bulb, Octopus Energy were cheaper for both gas and electricity but looking today, they seem to have far too many tarrifs, all of which are more expensive.
A couple of the suppliers are also 100% renewable energy.
As far as I know, no
suppliers offer 100% renewable energy. Bulb and others offer 100% renewable electricity and a percentage of green gas.
Even then, there's a lot more to it than just the on-paper percentages.
