Well just had an email from the OLEV 7kw charger people & ..........
They said new regulations require the 7kw charger will have to have it's own independent 100Amp double pole mains isolator switch supply which will have to be carried out by the distribution network operator, This shared loop power supply we have in these old houses is not up to being upgraded so a new supply is needed from the main feed in the street, That's what the electricity engineer said when he came to access the situation.
Do I want my garden/lawns digging up to have a new supply installed ! Not really.
It's supposed to be a free upgrade for old housing stock with an antiquated electricity supply, There are literally thousands of this type of housing stock in my neck o the woods.
Going to be a real problem for people in a few years time when they will want a BEV & home charger installed.
