That is for GAS. (Not the IEE regs bit, but the "competent" criterion.)
There is NO requirement for competence under Part P. After all, they're
allowing NIC-only-one-person-in-a-firm-needs-a-qualification-EIC to
self-certify.

(The main reason for a CORGI to sign off DIY gas heating installation is not
the Gas Safety Regulations but Part L requiring somebody to sign that you've
put thermostatic radiator valves in, and to qualify for some manufacturer's
warranties on the boiler.)

The IEE do 2-3 day courses. However, you would also need the apppropriate
test equipment which must be calibrated periodically.

It's quite clear(ish). One of the following applies:

- the work is within the definition of permitted work[1], not in a kitchen
or bathroom or other specified location - DIY permitted, providing work
complies with the Readers Digest Picture Book of Sockets and Switches.
- the work is carried out by a person [whose employer is] registered with a
certification body eg NICEIC - operative self-certifies
- anything else, a building regulations application to the council is
required

Much like windows with FENSA, etc.

works" form of certificate
