Nowt wrong with an extra cpc though, though not strictly required unless its a marina (i'm lead to beleive)
I probably wouldn't do it with SWA, but I'd always choose to install a cpc in steel conduit, not keen on trusting it through loads of separate joins, etc (and it may be alright now, but who knows what happens in the future?)
OT: People tell me conduit used to have to be tested with a high current tester, but there seems to be no reference to it anywhere these days?
I seem to remember hearing about high current testing for conduit / trunking, but I think it is fairly unusual to find a circuit not wired with its own CPC these days

Yep, if you suspect any conduit/trunking joint then a high current test can be performed.....BUT you can't do it with the cables in as if there is any resistance then the I²R heating could cook the cables
You're better off running in seperate CPCs every time
