A registered person must comply with regulations 9 to 19 in carrying on a regulated activity.

But paragraph (1) does not require a person to do something to the extent that what is required to be done to comply with regulations 9 to 19 has already been done by another person who is a registered person in relation to the regulated activity concerned.

For the purposes of determining under regulations 9 to 19 whether a service user who is 16 or over lacks capacity, sections 2 and 3 of the 2005 Act (people who lack capacity) apply as they apply for the purposes of that Act.
