This is _by far_ the biggest concern. I own a home, but it doesn't have a driveway much like the majority of Brits which means I rely on public charging for my EV.
In the UK, electricity supplied to your home is charged at a 5% rate of VAT. You can also take advantage of cheaper overnight energy tariffs that keep the price per kWh down to £0.03-0.05. Public chargers will charge a minimum of £0.55 up to £1 per kWh which includes 20% VAT.
That'll need to change for mass adoption here.
