The System Five analytics team have developed and deployed halo to monitor and report energy savings across our estate, which in turn provided invaluable data on ROI for projects undertaken. The service and technological approach surpassed our expectations and so we are discussing the rollout of livesight with an in-cloud bureau service for the New Year.

I have worked in multiple buildings throughout my career, meeting and seeing the work of BMS engineers. System Five are the only company that I could not find a single fault with, and their staff are super friendly and helpful. Their work is second to none and I can genuinely say the building I am currently working at would fall to its knees without the assistance of their rapid thinking staff. In terms of building management systems , they are definitely in the top tier of the trade. Excellent work all and we appreciate everything that you do for our company.

We have worked with System Five for many years and have always found them both professional and easy to work with. They have consistently provided us with a very high level of service on a variety of demanding projects such as Lambeth Palace Library and more recently the BAFTA HQ redevelopment. We hope to continue to work with them for a very long time.

Operations Manager

The Southampton Centre for Cancer Immunology project was Procure 21+ and System Five worked closely with SPIE to provide cost advice and a detailed design. At the installation/commissioning stage, System Five were self-sufficient and understood the standards required by the Client. The SCCI building housed a Pre-Clinical Unit, which had a precise method of control, System Five’s input was very important to gain the required validated approval. This gives testament to their collaborative approach and exploration of all possible control operations to ensure the facility was completed to the Clients’ satisfaction.
