Apprenticeship Spotlight: Insights from Owen Longton
As part of our commitment at Key Integrated Services (KeyIS) to nurturing talent and shaping the next generation of engineers, we offer apprenticeships that combine hands-on experience with industry insights. In this Q&A blog, we catch up with Owen Longton, one of our dedicated apprentices, as he reflects on his journey at KeyIS.
Q: What attracted you to KeyIS, and what have you been working on during your apprenticeship?
Owen: I was drawn to KeyIS because of its reputation for delivering comprehensive building services solutions. The company’s focus on sustainability and innovative engineering really stood out to me.
During my apprenticeship, I’ve been involved in a variety of tasks. Initially, I worked on estimating mechanical systems. This involved reviewing tender documents, extracting critical details like project specifications, and formulating cost estimates using estimation software. I’ve also spent time creating spreadsheets to organise cost data, which taught me the importance of precision and attention to detail.
As I progressed, I shifted to the design department, where I learned to use AutoCAD to create technical drawings, including gas pipeline layouts and pipe network designs for chemical facilities. I also calculated duct sizes and air handling unit (AHU) capacities, applying thermodynamic principles I’d studied at university.
Q: What skills have you developed during your apprenticeship?
Owen: One of the biggest skills I’ve gained is proficiency in AutoCAD, which is an essential tool for engineers. I learned how to create and modify 2D drawings, adhere to industry standards, and ensure accuracy in my designs.
I also honed my ability to calculate costs and understand the financial implications of design choices. Working closely with estimators helped me appreciate how decisions around materials and design complexity impact project budgets.
On the technical side, I deepened my understanding of HVAC systems, airflow calculations, and regulatory requirements for design and installation.
Q: How has working with experienced engineers shaped your apprenticeship?
Owen: Working alongside senior engineers has been one of the most rewarding aspects of my time at KeyIS. They’ve shared their expertise on everything from material selection to maintainability, emphasising the importance of adhering to regulations and industry standards.
The estimators, in particular, showed me how design and budgeting are interconnected, which was invaluable. Their mentorship helped me understand how engineering projects come to life—not just in terms of design, but also in meeting client expectations and ensuring cost efficiency.
Q: What have you learned from visiting project sites?
Owen: Site visits have been a real highlight. Seeing how designs are implemented in real-world settings gave me a deeper appreciation for the engineering lifecycle.
For example, I observed the installation of HVAC systems in a commercial building, which brought the design plans I’d worked on to life. I also saw how teams handle unexpected challenges like site conditions or supply delays. This underscored the importance of flexibility and proactive problem-solving, as well as clear communication between all stakeholders.
Q: What’s your biggest takeaway from your apprenticeship at KeyIS?
Owen: My apprenticeship has been an incredibly enriching experience. It’s given me hands-on exposure to mechanical engineering in the building services sector and allowed me to apply academic knowledge in a professional setting.
I’ve gained technical skills like cost estimation, project planning, and technical drawing, as well as a better understanding of industry practices and client relationships. Most importantly, this experience has reinforced my passion for mechanical engineering and given me a strong foundation to build on as I advance in my career.
