View our short webinar for tips
on how to complete your application.



Are you ready to get started with your application? 

  • You will need to provide a full career history, length and responsibilities of all job positions held - do not leave any gaps, even if some of these jobs were not in the RACHP field as non-technical management or responsibility experience is still relevant and will be taken into account. Tip - make sure you include details of different roles held within each company eg if you started as an apprentice and ended up as a managing director, make sure you include dates that you were in each different role throughout your career. Include any roles outside of RACHP for example if you returned to study or worked in a different sector so that there are no gaps in your CV. 
  • The Professional Experience section is where you can add examples showing the responsibilities of your work - here is an example. 
  • Have electronic copies of relevant qualifications ready to upload (eg Apprenticeship, NVQ, Degree, F Gas). If you cant find your qualification certificates explain this on the form in the "other information" area.
  • Makes sure you have the name and email address of at least one sponsor who is familiar with your work and has agreed to give a reference. Tip - this should not be a family member.
  • Consider what other relevant information you want to add. Tip - have you been active with societies and branches, are you a member of other Institutes etc if you have a CV with fuller details of your experience you can upload these as well.
  • Advancing your grade for existing members. You can use the on line process below to apply for advancement at no extra charge. However if you are considering applying for Fellow please see the Fellow application process here.
