I am due to upgrade my membership this year do I need to pay my subscription now?
Yes, if you are planning to upgrade your membership please ensure all your subscription fees are paid before upgrading. Once your new membership grade is confirmed any fees that have already been paid will be deducted from the amount due at that time.

What fees do I need to pay if I am upgrading my membership?
Depending on the membership grade you are applying for, you will either pay the annual subscription fee or the application and interview fee to complete your online application. Please see for more information.

For Fellow, Member, Associate and Licentiate applications, the subscription fee and Engineering Council entry fee will be due for payment once your membership is confirmed by CIBSE. If you have already paid the annual subscription fee for another grade, the difference between this rate and the new grade rate will be payable.

If you are applying for membership at one of our Closing Dates, please see for the information on the fees payable.
