Ive just ordered a PHEV and will be moving from EDF to British Gas, as @Jojoe suggests you get 5hrs off peak and half price electric on Sunday’s. The rate per kWh off peak is also lower than ESF @7.9p per kWh.
I was going to move in June but, given the price cap is lowering in July, I shall wait and start the ball rolling then!
However given you have an EV, wouldn’t Octopus intelligent be a better overall tariff?
