Carl I only have a PHEV, however, the majority of my driving is less than 30 miles, a full EV is going to be more economical on electric than an PHEV, to date I have used £10.75 of electric (@ 50 pence a kWh on Octopus Go) travelling 750 miles.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
