More importantly dont do it your self if you dont know what your doing i.e. what size and type of cable required, swa cable will be the choice most sparks will use (and should use) which is slightly more expensive the size depends on the current it will have to carry i.e how much current the hot tub is, how many amps it uses. but Part P regualtions and the law states no work is to be undertaken by anyone not part p registered hope this helped
