HVAC Controls in Essex
Alpha Controls designs, installs, and commissions HVAC control systems across Essex — from single plant room packages to multi-zone AHU and FCU installations across large commercial buildings. We work on distribution and logistics centres, commercial offices, retail parks, healthcare facilities, and education buildings, providing control strategies that maintain comfort conditions, meet Approved Document L energy targets, and give facilities teams the visibility and flexibility they need to manage the building effectively.
HVAC controls are the interface between the building's mechanical systems and the outcomes the building is supposed to deliver: thermal comfort, air quality, energy performance. When the controls are well designed and properly commissioned, the building runs efficiently and occupants don't notice the systems at all. When they aren't, the complaints and energy waste are both significant and persistent.
In Essex, we regularly take on HVAC controls projects where the existing control strategy has never been properly optimised — AHUs running to fixed schedules rather than occupancy, VAV systems with setpoints that don't reflect actual zone loads, chillers and boilers without properly tuned PID loops. These are not hardware failures. They're commissioning and control strategy failures that we can usually correct without capital expenditure on new plant.
What We Cover
- AHU control — supply and extract fans, heating and cooling coils, heat recovery, DCV
- FCU controls — four-pipe and two-pipe fan coil systems, zone-by-zone scheduling
- VAV systems — pressure-independent zone control, duct static pressure management
- Chiller and boiler plant controls — sequencing, lead-lag, efficiency optimisation
- Heat pump controls — air source and ground source integration
- Variable speed drive integration — BACnet and analogue speed reference
- Plant room controls — full sequence design and commissioning
- Approved Document L compliance — control strategies for energy performance certification
Areas We Cover in Essex
Essex logistics and distribution facilities along the A12, A13, and M25 corridors are a significant part of our work, alongside commercial offices and public sector buildings across the county.

Get in TouchFrequently Asked Questions
Do you design HVAC control sequences or only install to a design in Essex?
Both. We work from M&E engineer specifications when they're provided, and we design and specify our own control strategies when we're appointed directly or when the M&E design doesn't include detailed controls specification. We're experienced in designing sequences for all standard HVAC plant types.
Can you improve the energy performance of existing HVAC controls without replacing hardware?
Yes — this is one of our most common project types in Essex. Setpoint optimisation, occupancy-matched scheduling, PID loop tuning, and control sequence correction can significantly reduce energy consumption and improve comfort without replacing plant or controllers.
Do you provide HVAC controls for heat pump installations?
Yes. We integrate air source and ground source heat pump systems with BMS and local controllers, including weather compensation, source switching, and integration with backup heating plant. For Part L compliance, we design control strategies that demonstrate the required efficiency metrics.
