We help FM & M&E firms keep their buildings under control

This is usually caused by poor zoning in the BMS, stuck or failed damper actuators, miscalibrated temperature sensors, or solar gain. Alpha Controls carries out thermal surveys and BMS audits to identify the root cause, then reconfigures zones and adjusts control strategies.

Many BMS systems are commissioned once and never tuned again, running default schedules that waste energy. Alpha Controls provides energy audits and BMS optimisation services that typically reduce HVAC energy consumption by 20-35%.

Yes. Upgrading BMS and HVAC controls is a recognised measure for improving EPC ratings. Since April 2023 it has been illegal to let commercial property below Band E, with Band C required by 2027 and Band B by 2030. Alpha Controls helps meet MEES compliance deadlines through BMS upgrades.

As of January 2025, Trend has withdrawn all support for the 963 Supervisor. The recommended upgrade path is to Trend IQVISION, built on Niagara 4 with HTML5 browser access. Alpha Controls carries out 963 to IQVISION migrations, preserving existing IQ controllers where possible.

A small office fit-out with 20-30 fan coil units might take 2-4 weeks. A multi-floor commercial building with AHUs, chillers, boilers, and metering could take 8-16 weeks. Alpha Controls provides detailed programmes and works around tenant occupation.

A complete BMS failure means loss of automated HVAC control, wasting energy or causing shutdowns. Alpha Controls provides emergency same-day callout services across London and the South East, plus resilience improvements including controller redundancy and cloud monitoring.

Yes. Alpha Controls regularly takes over maintenance of Trend, Honeywell, and Distech systems installed by other contractors, providing full support including software changes, hardware replacements, and system extensions.

Yes. Alpha Controls specialises in migrating proprietary systems to open-protocol platforms using BACnet, Modbus, or LON, giving you freedom to choose your maintenance provider and integrate equipment from any manufacturer.

Buildings with legacy BMS or no controls typically waste 20-40% of HVAC energy. Modern DDC controllers with weather compensation and adaptive setpoints can achieve payback periods of 2-5 years depending on building size and current energy spend.

Yes. A well-configured BMS reduces energy consumption and carbon emissions by eliminating wasteful operation and optimising plant efficiency. Alpha Controls helps clients quantify savings and provides reporting data for carbon disclosure programmes.
