You're correct
@Salty Spuds but given that eventually we're going to be 100% reliant on electricity and that much of that electricity is already produced by harvesting the sun be that wind, tidal or solar panels then electricity being four times more expensive than gas is a stretch.
At the micro level when I'm out in my camper I'm already self sufficient in electric via solar or by driving aimlessly around in circles and while the same doesn't quite apply at home a £20k spend there could see a solar, battery, inverter and heat pump install that would knock a hole in that 25 p per kWh.
I see that 25 pence more as the reality of generating companies raking in the extra profit from being part of a monopoly product.
