Surely I can just put a 32A Type A Bi-directional RCBO in the new garage cu then supply the EV charger from that? Thinking 10mm² from house to garage then 6mm² from garage cu to EV charger. I'll have a measure up tomorrow and look at volt drop.
That just leaves the Cat-5 or Cat-6 from where to where?

You will actually need two data pairs back to the inlet side in your house. Your car charger and solar both need load info, so will both have their own CTs

Good point, cheers. PV is to be done "later"...my later
, when I redo the garage roof.I'll run the SWA in a bit of this in black with a 20mm one (or two) inside it for the data.

I did mine while on furlough during lockdown

Did similar recently, new fused switch in house with 10mm swa to garage.
I also ran a conduit for future me to put a cat cable in if I ever get an EV.
Hager RCBOs in the garage.

They look very similar to Wylex!
That depends. It needs to go somewhere where it can measure total in/out on your electrical supply. So if the garage is split off with Henlies it needs to get to the meter side of those.
However for our solar (Solaredge) it was an actual bit of equipment, not just a CT. So it needed a power supply itself, also needed so it can measure voltage as well as current.
If you go solar, are you planning a battery that can power everything during a power cut?

Solar as I say is down the line so not sure on that yet.
For the EV side I assume there's no problem to run a separate CAT-5 or 6? Cable tied to any surface mounted SWA or in it's own duct(s) within the SWA duct?
I'm half thinking it can run from the EV charger back to the garage cu, through the garage cu, tucked in the corner, maybe in a bit of trunking. Then out of the garage cu along with the SWA feed from the house.
I could run a combined SWA from house to garage but guessing that would only be good for either the solar or EV? Seperate CAT-5/6 seems better to me, one for EV and one for solar.
A bit of an aside / bummer is that firstly I'm going to have to have a smart meter fitted to take advantage of any EV charging deal. Secondly, I'm going to have to put the switch fuse / Type S RCD enclosure in its side in the current meter box. Third
, the new, all RCBO house cu is temporary, isn't staying in this position and will be changed for a larger unit. Tucked as it is right up by the ceiling in the porch. Eventually this will be coming inside the house (need to move walls and doorways to do it). Thus I have to consider leaving slack on all cables I run and then neatly coiling the excess for now.I believe it's not supposed to share a duct as data cable won't be rated for 240V. I ran 40mm duct solely for data and pulled in cable to meet my requirements plus at least one spare.
I had some special considerations. Firstly my Internet comes into the garage so I needed a dedicated link to the outside of our main router/firewall in the house. Secondly our meter is in an external cabinet, but the Henlies splitting off the garage are by the house CU, so cable route to meter vs house CU would need different excavated routes. That all said I have the following between house and garage ..
1. 25sq.mm SWA power
2. Cat5e garage to house CU, carries RS485 signalling for solar metering
3. Cat5e garage to house "home office" x3
3a Internet to outside of firewall
3b Solar inverter to router/firewall for monitoring and control (Ethernet)
3c Spare, same route garage to home office
If I need more Internet at the garage I can use the spare, or fit some network equipment.

It won't. The SWA will be in a 63mm black duct. The CAT-5/6 cable(s) will then be in a separate 20mm duct inside the 63mm duct. I ran the cables to my gate like that. There's a bit in the On Site Guide about separation distances and that suffices as I understand.

You can run without if your confident you won't blow your main fuse.

and don't take the fuse carrier marking as gospel, it may be marked 100A, but can hold 63A, 80A or 100A fuses, it's best to pull it and physically check.

Can I jump in on this, as it's relevant?
But, I'm in a similar, although earlier part of an installation.

I've got planned 16 mm T&E to the garage. That's for length of run and voltage drop. I've got 2 CAT6a ready for data, internet, and cameras at the garage/gate end, to go too. NAT will be in the garage (heated), hard-wired back to the house. Making a bit of a sub-network at that end.
Nothing is set in stone, and we're not that gadget hungry, just basics.
I've not thought about EV (although I'm refraining) or solar on the garage (which might be an option) but I'd always thought solar for the garage rather than the house. Question, should I run more CAT6a just in case or am I complicating when I don't need to. I think I've more question to answer before finalising anything. CAT6a I've got enough to run as many as I want, but wasn't planning on any more than a 12 port switch at the house.
