    Moving onto nvq 2357 from 2365

    Hi guys, I've recently completed my l3 2365 and I'm now looking to move onto the nvq 2357. Does any of the theory modules I've completed transfer or will I have to basically do the theory again? Thanks in advance

    Hot tub query for installation.

    I'm sure it's been asked before: But does a hot tub for outdoor use fall under section 702? (7671). I cannot find a reference specifically to a hot tub but a pool is close. And a second question why is there no real reference to SWA cable. When calculating travel distance is it the same as pvc/pvc.
