It will be installed and tested to the latest regs. If you accept thet BS7671 isn't a legal requirement on it's own, but is accepted as the required standard for the building regulations part P,
then if the Building Regs don't require it for a particular building then surely BS7671 doesn't apply. If you look at the Building Regs
The Building Regulations 2010

1. Subject to paragraph 2, a detached building—
(a)into which people do not normally go; or

Also definition of livestock and agriculture
The Agriculture (Miscellaneous Provisions) Act 1968 (1968 Ch 34)
The definition of livestock given in Section 8(1) of the Act applies to animals being kept for the production of food, wool, skin or fur on agricultural land.
Agricultural land is defined in Section 8(1) as land used for the purpose of an agricultural trade or business
Also if you read the Building Regulations Part P, Section 2, 'Scope' 2.2

From IET:
Q3: To what types of electrical work does Part P apply?
- In or attached to a dwelling
- In the common parts of buildings serving one or more dwellings, but excluding power supplies to lifts
- In a building that receives its electricity from a source located within or shared with a dwelling, and

The
common parts of buildings includes access areas in blocks of flats such as hallways and shared amenities in blocks of flats such as laundries and gymnasiums.
