Twin Walled Cable Duct - https://www.tlc-direct.co.uk/Main_Index/Cable_Index/Cable_Ducting/index.html

The ducting is a good idea as if you require any additional cables, like phone, ethernet or alarm cables, then these can be put in as well at any time. Just leave a pull core in.

You would need a separate duct then, as they are ELV.

If they are screened and insulation rated to mains voltage then there shouldn't be a problem.

Not if SWA, doesn’t that act as a screened cable? (In this instance)

Good question.

Yes, but without knowing what cable will be used I suspect the cheapest option will be the most likely. Many of these cables are only rated for 50V.

There’s nothing wrong with putting a 50V insulated cable next to an insulated and sheathed LV cable, however you can’t put it next to an unsheathed LV cable.

Hi all its me again.
Having had your initial advise and intending to get some conduit tomorrow. I have had a call from an electrician through my builder.com, when I sought interest re rewire.
During conversation I was informed that replacing the cable to the garage was not notifiable under part P as it is a replacement of existing cable.
I looked up a guide on Elecsa -NICEIC and it quotes
'All other electrical installation work is non notifiable - namely additions and alterations to existing installations outside special locations, and replacements, repairs and maintenance anywhere.'

confused I am

A rewire of a full installation or a single circuit is notifiable
