BMS Maintenance

Sirus provide BMS Maintenance services including Planned Preventative Maintenance (PPM), Reactive Maintenance, System Upgrades & Optimisation

Sirus service and maintain a number of different types of BMS including Sauter, Siemens, ABB Cylon and Tridium. Our services include…

Planned Preventative Maintenance (PPM)

On-site PPM & remote PPM of Building Management Systems – system checks & reporting.

System Upgrades

We will guide you through BMS upgrade and replacement projects always keeping efficiency and ROI to the fore.

System Optimisation

We will optimise your BMS systems to maximise system performance and reduce overall energy consumption and costs.


Reactive Maintenance

Sirus provide a 24/7/365 emergency callout services for Building Management Systems.


Our BMS service package includes motor control centre (MCC) maintenance, field devices, environmental monitoring, calibration of sensors and software maintenance and upgrades.

We advise on the viability of energy-saving systems such as control strategy optimisation, submetering, automatic meter reading systems, automatic monitoring and targeting (aM&T) systems, and lighting control solutions.

Our engineers can add or modify control routines including time control, humidity control, temperature control, pressure control, air quality control (CO₂, CO), weather compensation, optimisation and enthalpy control.

Our team has a combination of BMS, QBMS, mechanical, refrigeration, controls, electrical and thermodynamic skillsets. They are dependable, flexible, responsive and thorough.

Sirus engineers also have years of QBMS maintenance expertise from implementing and maintaining pharmaceutical systems in compliance with US FDA 21 CFR Part 11 regulations for electronic information management.

Our technicians continuously seek opportunities to reduce the carbon footprint and energy costs in buildings. We adopt the EN 15232 standard to implement smart control strategies in order to deliver sustainable buildings.

We believe that energy-efficient, healthy buildings are within reach for all types of organisations. It is technically feasible to achieve much higher levels of energy performance in buildings with existing technologies and it is also very cost-effective.

Digital Maintenance Solutions

In collaboration with our technology partners OPNBuildings, Sauter, and Siemens, Sirus provide futureproof solutions to run buildings efficiently and continually improve efficiency through self-learning. Alongside the traditional BMS, our Data Analytics System harvests the building information, analyses it, feeds back the results and acts upon this information to make the building continually perform more efficiently, economically and sustainably.

Automated Predictive Maintenance Routines

The BMS strategy carries out a scheduled routine. The system response is analysed. The performance report informs onsite needs-based maintenance.

Continuous Fault Detection & Diagnostics (FDD)

System data is continuously analysed to find faults, anomalies and opportunities to improve performance.

Asset Performance Tracking and Reporting

KPI based performance tracking for benchmarking across the building and estate.

Remote Analysis and Diagnostics

BMS and HVAC Systems experts on hand to analyse and diagnose issues remotely as they arise.

Occupancy Analytics

The building can predict occupancy ensuring space utilisation is managed effectively from cleaning schedules to maintaining occupant comfort.
