We've ordered two electric vehicles, and we're entitled to two home charge points, as shown here:

https://www.britishgas.co.uk/energy-saving-products/electric-vehicles

The charge points are now 7kw/32amp (up from 3kw/16amp), so if we have two in use at the same time, that's 64amps!(?).

When I spoke to British Gas, they said 2x7kw chargers should be fine if we have "two 100amp isolators", and if we don't, this is something that could be done (at a price) and I should speak to an electrician.

Before I do, I want to make sure I understand exactly what's required.. By "two 100amp isolators" I presume he's referring to the things we have two of here marked "RCD Controlled Circuits" (both rated 80amp).

Totals for the two sides here are:

Left: 6+6+16+32 = 60amps

Right: 6+16+32+32 = 86amps

"Water Heater" presumably refers to the immersion heater that will hopefully never need to be used. We have no electric shower. Oven ("Cooker", 32amp) is electric though hobs are gas.

What's the best way we can connect two 32amp EV chargers here?
