The work of an ACIBSE is characterised by the ability to act as exponents of today’s technology through creativity and innovation. You may:
maintain and manage applications of current and developing technology
undertake engineering design and development
be engaged in engineering manufacture, construction and operation.
Eligibility for ACIBSE requires you to be engaged in technical and commercial leadership and possess effective interpersonal skills. You will exhibit a personal and professional commitment to society, to your profession, and to the environment. This grade is achievable if you can demonstrate that you have the required professional experience and competence for ACIBSE.
Candidates who meet the academic standard for IEng can apply for registration with the Engineering Council. Please note applicants can still achieve ACIBSE without the exemplifying qualifications if they have the relevant experience.
This route requires candidates to demonstrate their competence through the submission of an engineering practice report (and supplementary documentation), followed by an interview assessment.
There are two UK application closing dates per year, February and August. Applications will be accepted throughout the year, however, interviews will be held during two designated interview periods each year. (April / May & October / November)
Overseas interviews will be held throughout the year therefore closing dates do not apply for candidates based outside the UK.
Factsheets and Application Forms
Technical Report Route
This is the second stage of the Alternative Route for those that don't hold the required academic qualifications for IEng registration with the Engineering Council (UK). Once you have gained ACIBSE you can go through our Technical Report Route (TRR) to gain IEng registration.
Engineering Council Registration Only
This is the second stage of the Alternative route for those who have undertaken appropriate further learning to Bachelors level and wish to apply for IEng Registration. You must currently hold ACIBSE to gain this registration with the Engineering Council.
Fast Track Routes
The following routes are for indviduals that have already demonstrated their competence with another recognised engineering authority. An interview is not required for the routes below, therefore applications can be submitted at any time during the year.
If you already hold IEng registration with the Engineering Council, you may be able to apply for ACIBSE via our fast track route. Applicants are asked to demonstrate their competence at IEng level in the building services engineering field through the submission of a 2000 word competence statement and supporting documentation.
Once you have submitted your application it will be reviewed by our staff and then sent to the Membership Panel for a final verdict. The Panel meet once every two months to assess applications.
European Directive Route
Watch a 5 minute presentation on the requirements here.
The European Directive Route is open to those who are already registered as a professional engineer by a recognised European Engineering Institution and who wish to join CIBSE at the Associate grade. Applicants must demonstrate their competence at IEng level in the Building Services Engineering field.
