as an apprentice i wired a garage which had abrand new supply taken off the supply to the street lighting lamppost next to it via a big ugly joint.

 
For info, studies are showing that most owners of EV's typically charge their EV's with around 80% capacity still left - so only top up overnight, around two hours max

Other points from the Birmingham Study and others:

Around 90% of all journeys are under 7 miles in length

70% of people drive less than 63 miles per week

Domestic EV chargers are designed only to trickle charge, you do not need a 3phase supply. The fast chargers - full charge in 30-60mins will be locallly available in most towns and motorway stations.

Some supermarkets are considering adding Free top up machines in their car parks for customer use.

You can charge via a 13A outlet but it is not recomended and may well be outlawed in this country.

A charger can be fitted for around

The bit on page 33 will be the most relevant to most people, but it is all interesting.

I have an idea that ALL DNO's have by law to publish a price list indicating how they arrive at their quote, but even so, most of it depends on luck and the person dealing with you. If they like you, cheap, if they do not, expensive...

Oh, forgot to say, have a look at the "construction" bit on page 80 onwards, this sets out the minimum and maximum charges for just about all "normal" work. You will all find this very interesting...
