How CIBSE Endorsed Status strengthened NBS' position as a leader in building services
NBS, a specialist building services consultancy, has always placed professional standards at the heart of its work. With a team of registered engineers accredited by the Engineering Council and active membership in leading institutions including CIBSE, IET, and ICWCI, the firm has built a strong reputation across commercial, defence, education, and healthcare sectors.
Why did NBS apply for CIBSE Endorsed status?
As the building services industry evolved rapidly—with increasing expectations around sustainability, energy efficiency, and digital innovation—NBS recognised that clients needed clear assurance their projects would be delivered by a consultancy with both technical expertise and professional credibility.
"We recognised that achieving CIBSE Endorsed status would not only validate our expertise but also provide independent assurance to our clients that our team consistently delivers to the highest professional benchmarks," explains the NBS team.
What was NBS's experience of the application process?
The application process exceeded expectations. Working through the requirements encouraged NBS to strengthen internal processes and implement new measures that enhanced their operations. When their application was accepted on first submission, the team was overjoyed.
"We initially expected to receive feedback or be asked to make revisions, so when our application was accepted on the first submission, the team was overjoyed," they shared. CIBSE's support throughout the process—including regular contact and a comprehensive criteria plan—made the journey clear, structured, and manageable.
How has endorsed status helped NBS foster a culture of learning and excellence?
The endorsed status has reinforced NBS's culture of continuous learning. The firm regularly organises CPD sessions and recently hosted their first CPD training and networking event in collaboration with CIBSE East Midlands, attended by all staff and distributing 75 tickets total.
NBS actively contributes to the profession at multiple levels. Joe recently joined the CIBSE East Midlands Committee, while three employees achieved CIBSE membership certifications. As a CIBSE Patron, the firm participates in CIBSE Annual, Corporate CPD, Patron Events, YEN, and Committee Meetings, with team members contributing as technical reviewers and membership interviewers.
What advice does NBS have for organisations considering CIBSE Endorsed status?
NBS's message to organisations considering CIBSE Endorsed status is simple: "Go for it. The process was much easier than we expected. If your organisation is already committed to quality and professionalism, the process is straightforward and very rewarding."
They emphasise what makes CIBSE endorsement unique: "As one of the most respected institutions in building services engineering, achieving endorsement demonstrates alignment with the very highest industry standards. For clients, partners, and staff alike, it speaks for itself."
How will CIBSE Endorsed status impact NBS's growth and future plans?
NBS has embedded their CIBSE Endorsed status across all communications—from websites and client documents to email signatures and social media. Looking forward, they plan to host further CPD and networking events, return to Ministry of Justice projects, and forge new connections with like-minded organisations.
"For us, it's not just an accreditation—it's a long-term investment in credibility, growth, and excellence," the team concludes.
