There are some subscription options from £5 a month which can reduce the tariff to 30-40p per kWh. Charging speeds are much faster now and the infrastructure much better too. I believe the above rates will work out, typically 40% cheaper than petrol, and given current AP’s on Motability, many EV’s are better value than petrol. It’s worth checking where your local chargers are and their costs. Costs vary. I had a choice of 3 Electroverse sites within a mile. A 15p difference.
