five years ago i did a pool repair. the year before i had bought all my own scuba gear for sport use, i used my gear for the repair, put the hire of equipment down on my books, unimportant that i hired it from myself. 500 quid through my books no questions asked. dont know if that was luck but it went through no probs.
missus just pointed out it was in spain so it might be different rules.
