Not according to Building Controls, when I raised this question, last year.A whirlpool bath surely is notifiable, as it is a complete unit installed as one item. Presumably it has controls on it which are accessible?
When doing some work in West Yorkshire.
I asked the question concerning, whirlpool and jet spa baths, if the panel was fixed and the a feed was taken from the otherside of the bathroom wall, directly to the conection beneath the bath, it did not need to be notified.
