Hi crypt0r, I am well familiar with the Royal College of Music, and would be happy the answer any questions.
The composition faculty, of course, is one of Britain's best. Mark-Anthony Turnage, who is as famous as any other European composer alive, maintains a very active status at College. In addition to teaching a number of principal study students, he also holds frequent masterclasses for all the composition students, where anyone can bring in scores and recordings to present. The other teachers there are fantastic as well, all holding excellent academic credentials with tons of real world acclaim. College holds weekly 'faculty classes' where the entire composition studio meets and welcomes guests lecturers - this year they have included Julian Anderson, Roger Redgate, Simon Holt, Daniel Strong Godfrey, Michael van den Aa, Dai Fujikura, and Krystof Penderecki.
There is an active film composition scene as well, with industry giants such as Joseph Horowitz teaching at College. I believe that there is no straight up postgraduate degree in straight-up electronic music composition, however there is a very active electronic scene. Michael Oliva is the area leader, and has a well known reputation in London. He teaches a number of electroacoustic classes at both Undergraduate and Postgraduate levels and is an open and approachable person for tutoring.
The College has a state-of-the-art studio, with several soundproofed audio recording and experimentation rooms. There is a Composition Suite, which has a number of "workstations" (i.e. computers with MIDI keyboards, synthesizers, and loaded with relevant software) that can be booked by any composer at anytime from 8AM to 10 PM weekdays (pending they are not in use by a class at the time). Computers in the Suite are MAC-only. They come equipped with Logic and various synthesizer software for additive, subtractive, FM, granular synthesis, etc etc etc.
Outside the studio, the college is more PC-oriented. There are about a dozen in the library, another dozen in the canteen, eight in working/study suite by the practice rooms, about two dozen in the dormitory, and various more at kiosk locations around campus. All these PCs come equipped with Sibelius, and have full printing facilities (including double sided and A3, A4).
The library has an impressive selection of scores and recordings, as well as one of Britain's most important research/reference collections for music. CD's and DVDs cannot be checked out, but College maintains a subscription to Naxos Music Library online, which anyone can access at any time some 10,000+ online CDs. Free internet WiFi access is available to all students at anywhere on campus and in the residence hall.
Several ensembles that play new music are in-residence at College. They include an orchestra, and a few large ensembles and chamber groups. Many workshops where they read and perform music are scheduled throughout the year. Participation in many of these workshops are required for all the composers, and all readings and rehearsals are recorded
