Since starting this I have checked with the company who are authorised
to make copies and their website tells me that they require a letter of
authorisation to prove that I am entitled to ask for a copy.

It doesn't say how I find out who is the authorised person that provides
the letter (nor how they keep their records up-to-date when that person
changes - which in this case of this property it almost certainly has,
not necessarily to someone who knows that they have this responsibility)

It will almost certainly be whoever is responsible for the common areas.
