In the event the passenger doesn't show up or if the bag highly likely contains a bomb, the bomb squad is called, and the bag is blown up. No terminal dumping required.

I don't know at what stage of the UK screening process it's done, but a bag may be sent to a decompression chamber to give a chance for potential bombs to detonate.
