• How are membership grades allocatedAll applications are reviewed and evaluated by our Membership Committee against the membership grade criteria. The Committee are a group of volunteers with extensive knowledge and experience in the sector. New applicants are reviewed by the Committee monthly and applicants are allocated the most suitable grade of membership based on the information and evidence they provide about their roles, experience and qualifications.  Applicants are asked to give their consent to the grade allocated and may appeal or provide more information if available. For a more detailed explanation of how the Member Grades match experience and qualifications download and refer to the Membership Grade Guidelines.
  • What is the difference between Associate (AMInstR) and Member (MInstR) Grade? Membership grade is allocated in recognition of high levels of responsibilty, experience and/or qualifications.   Associate Members are those who do not have sufficient experience or responsibility to meet the Member grade but still have considerable practical skills in refrigeration or an associated industry and theoretical knowledge. They may also hold a practical qualifications such as an HNC or Level 2 apprenticeship with a few years of experience.  Associates will often apply for advancement of their membership grade after they have obtained a few more years experience or increased responsibilities at work. Associates are able to use the initials AMInstR after their name and take an active part in influencing the future of the Institute by voting in Elections and standing for Executive Council.
  • Do I need to have RACHP qualifications to join? Not necessarily, the Membership Committee take account of both experience and qualifications. For example if you can prove that you have had a highly responsible job in the sector for over 10 years you could be eligible for full Membership.
