In the early 80s there was a bit of business traffic and flying training along with a small number of privately owned light aircraft. Names that come to mind are Eagle Aircraft Services, operators of a variety of King Airs at the time, and for GA, David Fairclough Aviation, Leavesden Flight Centre and Leavesden Flying School, the last growing out of the ashes of the first if my memory serves. I vaguely recall also one or two HS125s (600/700s, I think) and Learjets, but I think these may have been performance limited and always had to position out before doing anything commercial. But I may be wrong, it's a looong time ago.....
