Model Forms

There are four primary publications within the IET’s model forms of electromechanical contract series:

  • MF/1 is intended for use in home or overseas contracts for the supply and erection of electrical, electronic or mechanical plant
  • MF/2 is intended for use in home or overseas contracts for the supply only of electrical, electronic or mechanical plant
  • MF/3 is for use in home contracts for the supply only of electrical and mechanical goods where no initial design or subsequent installation or commissioning is required.
  • MF/4 is for use in home or overseas contracts for the engagement of an Engineering Consultant.


'Home' contracts include those under the laws of England and Wales, Scotland or Northern Ireland.
