What wiring will be required for Solar, ev charger and powerwall in external garage

[Roaders]

Hi All

I am buying a new house soon and plan to get quite a bit of work done to it - but not all at once.

Initially I am planning a kitchen extension and moving around some internal walls.

Eventually I would to add solar panels, EV charger and power wall to the garage which is a separate building around 3 meters from the house. (the consumer panel is in the house under the stairs).

When I get the extension built floors will be dug up, plaster will be removed and the house will generally be a big mess.

What I would to do is to avoid more mess and dug up floors / plaster damaged when I come to do work on the garage later.

What wiring will I need between my consumer unit in the house and my garage to support this? Is it sensible to cater for this when I do my initial extension work?

Thanks

I suggest you put in a 50mm duct and 2 x 20mm ducts for future improvements.
With draw rope installed

As James, your requirements may change, so a duct that can have various options is best.
Keep the bends up at each end shallow, so it's easier to draw the cable(s) in.
