Mini case study: Local leisure centre

Control system stabilisation and operational improvement

A local leisure centre was operating with control services running continuously, limited user-friendly graphics, and little visibility of system performance. The site was experiencing over 500 active alarms, making day-to-day operation difficult and masking genuine issues.

By spending time on site with the client, we established a clearer understanding of how the building was being used and the challenges faced by the operations team. We then reworked the control strategy, improved system logic, and introduced a more user-friendly approach to graphics and displays.

  • Alarm count reduced from over 500 to zero
  • Control strategies corrected and stabilised
  • Systems now operate smoothly and predictably
  • Regular system backups implemented for resilience and recovery

How we work

  1. Understand the site — We take time to understand your building, existing systems, and operational priorities.
  2. Provide clear, practical advice — Options explained in plain language, focused on what suits the site.
  3. Support long‑term performance — Ongoing support, proactive monitoring, and optimisation.
