Locations

Yep, Janner, you're right. It was Brunel University, and The Comic Strip were far from being alone in using the university for location shooting. Check this out from Wikipedia:

"Some scenes from A Clockwork Orange were filmed on the Uxbridge campus. Lecture Theatre 'E' was used for the 'aversion therapy' scene. The campus has also featured in an episode of The Comic Strip Presents first series entitles Summer School, where the area in front of the Lecture Theatre is turned into an Iron Age settlement. It was also used as the location for a number of episodes of 1970s police drama series The Sweeney.

Several films used the Runnymede campus as an outside location, particularly in the 1940s-1960s. The Boulting Brothers' A French Mistress, 1960, made extensive use of the campus as a boys' boarding school where an attractive new French mistress causes frictions and hilarity. It is often claimed that The Belles of St Trinian's was entirely filmed at Runnymede, but on watching the film it is evident that the main school building is not, in fact, President Hall, but Oakley Court in Water Oakley (just the other side of Windsor) - also seen in many a Hammer horror classic. However, a number of other locations in the film are at Runnymede, including the Mews being seen (from Cooper's Hill Lane) as a dairy. The hockey match takes place on the field between Chestnut Walk and the workshop buildings."
