AST at Perth run short JAR 66 modular courses . I assume your mate as an Engo has a degree or HNC, this may give him some exemptions. Try the CAA website for more info on JAR 66, if you give the people at Perth a call they are generally very helpfull.
CSE at Kidlington near Oxford used to run short courses for the various sections under the BCAR licencing system also Southall college ?.
Good Luck.
