What BMS Maintenance Involves
Understanding what happens during a scheduled visit — and why it matters.
- Controller health checks — verifying CPU status, memory, and comms integrity
- Sensor calibration verification — confirming temperature, humidity, and CO₂ sensors are reading accurately
- Actuator stroke testing — checking damper and valve actuators move through their full range
- Software trend review — examining logged data for anomalies, drift, or inefficient control sequences
- Alarm log audit — reviewing active and historical alarms to identify recurring faults
- Time schedule review — ensuring occupancy, setback, and holiday schedules are current and correct
- Condition report — a written summary of findings, recommended actions, and risk ratings
Reactive maintenance — responding only when a system fails — almost always costs more than planned servicing. A failed actuator discovered during a routine visit is a minor parts-and-labour expense. The same fault left undetected can cause a heating or cooling zone to run unchecked for months, wasting energy and masking deeper control issues.
Preventive BMS maintenance visits surface small faults before they escalate. Sensor drift is corrected before it causes occupant complaints. Alarm floods are traced back to root causes rather than silenced. Time schedules are kept aligned with actual occupancy patterns, delivering measurable energy savings across the building.
For building owners and facilities managers across London and the South East, a structured preventive maintenance contract with Alpha Controls means fewer emergency callouts, lower energy bills, and a system that reliably delivers the comfort conditions your occupants expect.
Third-Party System Support
Alpha Controls maintains BMS installations regardless of who originally designed or commissioned them. You are not tied to your original contractor.
Full support for the Trend IQ series controller range and the IQVISION supervisor platform, including IQ3, IQ4, and legacy IQ2 hardware.
Maintenance and fault diagnosis for Distech ECB series controllers and the ECLYPSE Connected System platform.
Support for Honeywell WEBS-AX and WEBS-N4 supervisor platforms and the associated field controller estate.
Servicing and optimisation for Siemens DESIGO CC building management platform and PXC controller hardware.
Maintenance for Schneider Electric EcoStruxure Building Operation and legacy TAC Vista and Andover Continuum systems.
We support legacy and proprietary BMS installations where the original vendor or contractor is no longer available or the system has reached end-of-life support.
One contractor. Full support. No lock-in.
Whether your building runs a single BMS platform or a mixed estate of controllers from multiple vendors, Alpha Controls provides a single point of contact for all maintenance, fault diagnosis, and system improvements. We work to manufacturer-approved procedures and carry manufacturer certification where available.
Remote Monitoring & Alarm Management
Proactive fault detection that means problems are often resolved before your facilities team is even aware they exist.
As part of the Enterprise maintenance package, Alpha Controls connects your BMS supervisor platform to our remote monitoring infrastructure. Alarms generated by your building’s controllers are routed in real time to our 24/7 response team, who triage each alert and determine whether it requires immediate remote intervention, a scheduled engineer visit, or simply logging for review at the next maintenance inspection.
Many faults — a runaway setpoint, a stuck actuator command, an incorrect time schedule — can be corrected remotely via the supervisor platform without any site attendance required. This reduces disruption to building occupants and cuts the cost of reactive callouts significantly.
Remote monitoring is available for Trend IQVISION, Distech ECLYPSE, Honeywell WEBS-N4, Siemens DESIGO CC, and Schneider EcoStruxure Building Operation. Where a site has an older supervisor, our engineers can advise on upgrade options that make remote connectivity viable.
- 24/7 alarm routing to the Alpha Controls response team
- Real-time fault triage — urgent, advisory, or log-only categorisation
- Remote remediation of software-level faults where possible
- Monthly alarm summary reports with trend analysis
- Escalation to on-site attendance when remote resolution is not possible
- Integration with your facilities helpdesk or CAFM system on request
Remote monitoring is included in the Enterprise maintenance package. Speak to our team to discuss connectivity requirements and whether your existing supervisor platform supports secure remote access.
Frequently Asked Questions
Common questions about BMS maintenance contracts and what to expect.
Yes. The majority of systems we maintain were installed by other contractors or as part of large construction projects where the original systems integrator is no longer involved. Provided we can obtain adequate system documentation — or reverse-engineer it from the installed hardware — we can take on full maintenance responsibility. We cover Trend, Distech, Honeywell, Siemens, Schneider Electric, and a range of older proprietary platforms.
A typical preventive maintenance visit includes a controller health check, sensor calibration verification, actuator stroke testing, a software trend and alarm log review, a time schedule audit, and a written condition report. The frequency of visits depends on your chosen package: annual for Essential, bi-annual for Professional, and quarterly for Enterprise. All visits are carried out by qualified BMS engineers holding manufacturer training where applicable.
Yes. Emergency BMS callout is available to all contract customers, with 24/7 cover included in the Enterprise package. Professional package customers receive priority response during standard hours with an agreed response time. All contract customers benefit from discounted callout labour rates compared to ad-hoc arrangements. We cover London, Kent, Surrey, Essex, and Hertfordshire for on-site attendance.
The cost of a BMS maintenance contract depends on the size and complexity of your installation, the number of controllers and field devices, the platform type, and the level of cover you require. We provide fixed-price annual contracts with no hidden costs. Contact us for a free site assessment and maintenance proposal — we will survey the system, document the scope, and provide a clear price for each of our three packages.

Frequently Asked Questions — BMS Maintenance
What is included in a BMS planned preventive maintenance contract?
A BMS PPM contract from Alpha Controls includes: scheduled visits (typically twice yearly) to inspect, test, and clean all controllers, sensors, and actuators; software backup of all controller programmes; review and adjustment of control schedules and setpoints; trending and alarm analysis; minor software changes within agreed hours; and a written service report after each visit. Our Professional and Enterprise packages include additional visits, remote monitoring, and emergency callout cover.
How often should a building management system be serviced?
Industry best practice (CIBSE AM14) recommends a minimum of two BMS maintenance visits per year for occupied commercial buildings — typically one in spring and one in autumn, aligned with the changeover between heating and cooling seasons. Buildings with critical plant such as data centre cooling or healthcare HVAC should have quarterly visits as a minimum. Alpha Controls advises on the appropriate frequency based on your building type and criticality.
What emergency callout response times do you offer?
Alpha Controls offers same-day emergency callout response across London and the South East. Our engineers are based in Gravesend, Kent, giving rapid access to all London boroughs, Kent, Essex, Surrey, and Sussex. For clients on our Professional and Enterprise maintenance contracts, a 4-hour on-site response is guaranteed. 24/7 remote monitoring with telephone support is available on all contract tiers.
Can Alpha Controls maintain a BMS installed by another company?
Yes. Alpha Controls regularly takes over maintenance of Trend, Distech, Siemens, Honeywell, and Tridium Niagara systems installed by other contractors. We begin with a full system audit that documents the as-installed configuration, identifies any outstanding defects, and establishes a baseline for future maintenance. Access credentials are transferred to Alpha Controls, and we take full responsibility for the system from handover.
What is the difference between planned preventive maintenance and reactive maintenance?
Planned preventive maintenance (PPM) is scheduled work carried out on a regular basis to keep the BMS in good working order — regardless of whether a fault has occurred. Reactive maintenance is carried out in response to a reported fault or failure. PPM significantly reduces the frequency and severity of reactive callouts by catching issues before they cause system failures. Alpha Controls recommends a PPM contract as the foundation, with reactive callout cover as a safety net for unexpected failures.
