You can apply for short-term work experience and summer placements and internships with both small and large companies to kickstart your career.

Working in the field can help develop contacts and provide a variety of opportunities for new entrants to develop their networking circle and build on their knowledge of the building services industry.

Typical Employers

Building services engineers often specialise in a certain area of expertise such as electrical or mechanical engineering. The field, however, is becoming increasingly diverse and multidisciplinary with the opportunity to choose more than one specialism.

Typical employers include:

  • Building services consultancies
  • Building contractors
  • Architectural firms
  • Facilities management companies
  • Construction companies, consultancies, and contractors
  • Engineering consultancies and contractors
  • Property firms and developers

Professional Development

Building services engineer must undertake Continuing Professional Development (CPD) through various courses to ensure their knowledge and skills related to the profession are up-to-date.

CPD has become an integral part of a professional career due to an increased rate of change in technology, best practices, and regulations, along with an increase in the number of specialisms. You can no longer obtain a professional qualification and then work for the next 50 years without any advancement or learning.

Once you have completed your training as a building services engineer, the next step is to become a professionally registered building services engineer. To do this, you must register yourself with the Engineering Council and become a member of the Chartered Institution of Building Services Engineers (CIBSE).

The CIBSE offers a guide for CPD with current practices and how to make your training as effective as possible.

To acquire the title of Incorporated Engineer (IEng) or Chartered Engineer (CEng) you must demonstrate professional competence in:

  • Knowledge and understanding of design and development of processes
  • Communication and interpersonal skills
  • Accountability and responsibility
  • Management and leadership
  • Professional commitment.

Professionals need to keep up with the advancements in technology and processes in building services engineering. They can do this by taking up professional courses, attending conferences and workshops, or pursuing further education.

If you’re interested in working on historical structures and their conservation, you can do a specialist course with the National Heritage Training Group.

Career Prospects

A building services engineer’s career generally begins as a graduate engineer, progressing to senior engineer with bigger projects and teams to work with.

With adequate skills and experience, you can move into senior project management, quantity surveying, or engineering design.

The typical career progression for building services engineers follows the pattern of: graduate engineer, senior engineer, project manager, senior manager, and finally building services director.

Career patterns aren’t fixed and you can find opportunities to develop your career according to your field of interest and the employer you work for. It is very important to be well-informed and well-researched about the industry you choose to enter, along with the cultures and working environment of different companies.

Promotions are dependent upon skills and experience, which is why it is important to undertake CPD both on and off-the-job. Working for an employer who allows you to choose your area of specialisation can help you develop your skills with more opportunities to work overseas.

Alternatively, you could impart your knowledge and experience by teaching at a college or university, or become self-employed where you will have the freedom to grow, set your own timings and rates, and look into more specialised work.
