Hi Harry - not got that far yet! MG garage has pointed me to Rolec as their approved one. I've been looking at Podpoint as well.
A quick look at my incoming supply and fuse box shows an less than up to date situation and I only have a 60A main fuse so not sure on the implications really.
Then there seems to be a question of tethered or not - given I have to get a type 2 to type 2 cable anyway, I'm not sure why tethered would be preferred?
Tethered is better as it saves having to dig out your cable.
A home 7kw charger needs about 30amps and if you sign up to Octopus Go's 4hour off peak tarrif, (5p/kwh from 00:30-04:30) it doesn't matter whether you have an electric shower and./or cooker assuming you'd not be using either during the night.
(I have a 60amp main fuse, electric shower and cooker and haven't blown it)
Untethered sometimes helps as you can often get a longer cable that way. Also lets you take it with you on hols for use at remote 7/77 kW chargepoints. Mine's untethered, sits in gge & can trail under gge door so is in effect tethered, until I want to travel far. Not so good for outdoor mounted EVSEs as you have to think about cable security.
I went for untethered because of our charger location and neatness. Some of the tethered chargers have really good cable management solutions so are fine, we were being offered projectEV and that didn’t look like a neat option. There’s definitely appeal in not having to get the cable out and pack it back into the car every time.
