Our Story

Organically Grown

We're proud to say that we've grown organically, without any external investment. Instead, we've relied on our own success and the hard work of our incredible team to fuel our growth.

Our success is a testament to the passion and dedication of every member of our team. Together, we've built a company that's financially secure and deeply connected to the needs of our clients. We believe in the power of collaboration, innovation, and genuine care for the solutions we provide. As we continue to grow, our focus remains firmly on delivering successful outcomes for our clients time and time again.

Formally owned by Centrica, BMSI was purchased by BESG in 2017.

BESG is funded by individual private investors, all of whom have a successful track record in the BMS industry.

Since 2017 BMSI has grown organically from 135 employees to 198 employees.

Turn over has risen from £18.5 million in 2017 to £31 million in 2023.

Our Team

What Our Team Says About Working at BMSI

Here's what some of our wonderful team members have to say about why they love working at BMSI.

Ed Baldwin
BMS Project Manager

“I've smashed the 7 month marker with BMSI! How time flies… It's been a fantastic opportunity to grow and support engineers in delivering great results for clients in both BMS upgrades and new projects! I've had the pleasure of working with EcoStruxure, Trend, Siemens, Tridium & Phoenix Contacts on various sized projects, large & small. They say variety is the spice of life.”

Sol Coburn
Support Engineer

"I have thoroughly enjoyed my time at BMSI so far and have felt well-supported with anything I needed. The team has a wholly positive outlook, and it feels as though everyone shares the same goals. I look forward to progressing further and trust that BMSI will be able to support me in that."

Samantha W
Business Development Manager

"With 14 years at BMSI, I've had the privilege of witnessing the company's growth and evolution firsthand. I started with the company as a Co Ordinator for our London Service Region before transitioning into my current role of BDM. The switch gave me new challenges, but I always had the unwavering support and guidance provided to me by my team, equipping me with the skills and knowledge necessary to exceed my goals and targets.

What I enjoy most is the dynamic nature of my role, each day presents new opportunities to learn, build relationships and drive growth for the company in a supportive environment. It's this perfect blend of challenge and reward that fuels my motivation. Being part of BMSI enables me to contribute to the success of the company while constantly evolving and expanding my professional skills.

I’ve met some amazing characters and made great friends over the years at BMSI, and I can honestly say my favourite aspect of the company is the people."

Shayne Wilson
Business Development Manager

"My first three months have been great. I’ve really welcomed into the team and found the business has really tried to get to know me, in order to work out how to support and develop me. My line manager, Brian, has been great in helping me learn about the business, our products and together we’re finding more ways to take those services to market in specific sectors – such as hospitality, education and manufacturing within the North-East region.

I’ve been able to give knowledge and experience back to the business. But also the business has given me access to opportunities and markets that I would not have found elsewhere. I’ve been delighted to attend a number of events within the last 3 months, and also present a business case for BMSI to attend one in June 😊

I'm exceedingly happy with my decision to join BMSI, it has exceeded my expectations."

Ali A
Support Engineer

“I’ve been working with BMSI for a year. I had been working as a BMS installer for 11 years, and decided to further myself into servicing and commissioning. Going to a different site everyday to make sure it's functioning how it should and preventing breakdowns. I enjoy call outs and figuring out what a solution is to a problem. Knowing that my knowledge is being utilised, and being pushed in a proactive way so that I can become a much more dynamic engineer to suit each individual client's needs.”
