Spoiler:
The BBC version you saw was a very badly cut down version (a fuller version is on the Norman J.Warren Coffin Box Set )
A much nastier notorious "Japanese" version of the *bedroom scene* is still floating around on European video releases, if you can find it.
"However, the stronger "alternate Bedroom Scene" on "Satan's Slave" (=Martin Potter cuts the girls clothing off with scissors and passes the scissors over her body in a threatening manner before she throws him off and attempts to escape, which is when he kills her) did indeed run into problems with the BBFC, hence its deletion from the list of extras.
The Director Norman J.Warren himself stated that the bedroom scene was not one that he ever wanted to shoot, and was forced on him by the producers, hence he left it out of his cut of the film. The BBFC then rejected ABUK's decision to include it as a bonus feature"
