I have the MG ZS EV and 99.99999% of my charging is done at home. I have only needed to use a public charger a couple of times in my life. But that will change, as I am planning a road trip / holiday in the next couple of weeks. I will travel from Warwick to Cumbria and then on to Scotland, before driving from North to South Ireland and back through wales. There will be plenty of sight seeing and I expect to do a couple of thousand miles or more. I can't guarantee charging at night, as I will stay in random B&B, as well as random / wild camping (nothing booked), so most of my charging will be public (with the exception of staying with friends for a couple of days). I am tempted to sign up for the free 3 months with Polar plus and then cancel when I get back home. Is this my best option, or are there cheaper options?
If it’s free, then you may as well have it?
Warwick to Cumbria, at the Cumbria end you’ll have plenty of Instavolt chargers to choose from and they’re pay as you go.
As you venture north from there, it gets more fractured, but Ionity are at Gretna and then there are plenty of ChargePlace Scotland rapids about. You’ll need the CYC App for those.
There are also a few Polar and Instavolts throughout Scotland as well though.
Have a look on Zap Map, and have a poke about near the places you’ll be going to and see what’s around.
I don’t make full use of my Polar subscription, ie I don’t save the £7.99 each month from being a member and the reduced pricing, but I like to have it as a convenience thing. Polar Instant would probably make more sense for me as a low user though, maybe that would be best for you after the trial as well?
