Im looking at a new install of a number of LED columns and ELV ground up lights I was after some advice on the requirements for RCD protection. Thanks

The BGB will give you a lot of advice for what you need to know.

The site has a landlords supply in an IP enclosure. This will be used to supply a mix of 1m columns, 4m columns and led up lights all fed via 10mm 3 core SWA. The lighting designer has also suggested that the supply's for the led up lights will be run into adjacent buildings where the ELV transformer will be mounted and then run out to the fittings. This doesn't sit well with me as the tents will have no way to isolate the point. Also the 1m columns have no room for 1 10mm cable let alone 2. Any advice would be a great help.

Use sub marine joints that way you can run the 10mm swa cable around and joint a 2.5mm SWA at each light to feed it

If the 1mtr post lights have no provision for glanding the SWA and a fuse cutout/isolator then I would install a root box near the base of each post might not appeal to the client though.
You can get ones made by a firm called NAL that have a mounted IP rated enclosure with gland plate and double pole isolator and fuse unit.
