southern duel
There will be bits of the answer all over the place; you have quoted MATS part 1 already....but there will also be MATS part 2 [local ATC instructions] but I can't reproduce them here due intellectual rights. There is a sort of requirement in CAP 168 Licensing of Aerodromes; Chapter 10 1.4 lists information, the details of which should always be available.......of course "being available" is not much use if there is no information delivery procedure in force. The Airport operator will also have manuals and procedures to promulgate information. Do not immediately point the finger at ATC. All ATC practices and procedures come under the watchful eye of the "regulator"...the CAA....nothing is done or not done without their approval.
