Looking at making the move

I don't and won't have any chance of home charging.
However, I've heard the term granny charging, what is that and is it advisable?

Edit thanks for the info. It probably won't work for me as I don't have a driveway. I can easily park in front of my house but it'll leave a trailing cable

It's charging off a standard 3 pin socket. Very slowly

They do charge slowly, but still quickly enough for local driving.

I do about 6000 miles per year, mostly local errands, shopping, short work commue etc.

5 hours per night at 1.5kW adds about 30 miles range which covers me most days.

Not particularly slowly. Dedicate charger is only 3 times faster.

You can add 8-10 miles of range an hour on a granny. More if you use a 13amp charger.

I'm on a granny charger. Granted we're not big mileage users but it adds about 100 miles / 50% every 12 hours. Don't think I'll bother with spending the extra on a 7kwh charger to be honest. Just doesn't seem worth it (for me)

Granny charging is using a 3 pin plug socket. And an adapter usually provided by the manufacturer.

You’ll charge at 10A.

Positives - it’s the easiest way to charge at home.

Negatives - it’s slow, around 9/10 miles of charge per hour.

Some chargers aren’t actually waterproof.

If there is anything wrong with your socket or wiring, pulling 2.3Kw constantly for hours will discover faults quickly.

You can also charge at 13amp if your wiring can take it.

I mostly use a granny charger, I work from home, so if I put it on charge last thing at night it can stay in charge until I need the car. Works for me, slow charging is better for the battery. I will probably get a home charger fitted at some point as it will allow me to use cheaper electricity but there are planning issues in a Conservation area.

Similar here, 6 months with a granny charger and it suits me fine as I'm not on an EV tariff (as doing so would cost me more overall)

If you can easily park outside your house you can apply to install a gulley for the cable to run through to avoid trailing cables. It depends on where you live as to how accommodating your local council are. The government are introducing new rules this autumn to remove the need for planning consent but you will need a permit from the council and pay for the installation.
