Your claim that Ofcom is in any way a "self-regulation body" is untrue. And frankly also a straight-up insane thing to say, sorry.

Ofcom was created by the UK government for the sole purpose of enforcing laws passed by the UK government [and sometimes interpreting those laws]. It acts on behalf of the State at all times, and is not empowered to do otherwise under any circumstances EVER.

You appear to be confused about what being a "quango" actually means in this case. "Quasi-NGO" means that while it appears to be a non-governmental organisation, it is not one. Ofcom's at arm's length because the majority of its daily legal obligations are closer to judicial than administrative, and it is UK custom (rightly) to not put judicial functions inside government departments.

While you're correct about Ofcom, the real distinction isn't really to the objective, but to the classification of its employees.

Ofcom, Gambling Commission, and the rest of the quangos are independent statutory bodies, and (this is a big distinction!) their employees are not civil servants.

Quangos include judicial tribunals and places like the BBC, or the Committee on Climate Change- it is a broad umbrella.
