AHU Electrical Installation Services
Our AHU electrical installation service covers the full scope of electrical works associated with air handling unit projects across commercial, industrial, healthcare, education, and data centre environments throughout the UK.
With extensive experience on equipment from the UK’s biggest AHU manufacturers, our engineers arrive on site familiar with the units they are working on — reducing installation time, minimising errors, and ensuring every installation is carried out correctly from the outset.
Our AHU electrical installation scope includes:
- Cable containment installation — cable tray, trunking, and conduit to and around the AHU
- Power and control wiring to fans, motors, heaters, valves, and damper actuators
- Wiring to AHU sensors and field devices — temperature, humidity, pressure, and air quality
- EC fan electrical installation and control wiring
- Control panel installation and connection
- Full installation in accordance with manufacturer schematics and BS7671 wiring regulations
Our AHU electrical installation service is available as a standalone scope or as part of a fully managed electrical and controls package covering installation, testing, commissioning, and certification.
AHU Bolt-Together & Flat Pack Assembly — On-Site Support
Many modern air handling units are delivered to site as flat pack or bolt-together assemblies, requiring skilled on-site build before electrical and controls works can begin. Arcane Power & Controls have extensive practical experience supporting AHU flat pack and bolt-together builds on site, working alongside manufacturers and main contractors to ensure the build and electrical installation are properly coordinated from day one.
Our involvement at the build stage means electrical and controls elements are considered and incorporated throughout the assembly process — not retrofitted at the end. This joined-up approach reduces rework, saves programme time, and results in a cleaner, more professional installation.
Where minor mechanical assistance is required in the course of our works, our engineers can help where reasonably within scope — reducing the need for additional trades on site and helping to keep labour costs down.
Our AHU site services include:
- On-site support during flat pack and bolt-together AHU assembly
- Coordination of electrical installation alongside the mechanical build process
- Liaison with AHU manufacturers, M&E contractors, and main contractors on site
- Minor mechanical assistance associated with the electrical and controls scope
BS7671 Electrical Testing & Inspection for AHU Installations
All AHU electrical installations carried out by Arcane Power & Controls are tested, inspected, and certified in full accordance with BS7671 — the IET Wiring Regulations — as standard. Every installation we hand over is accompanied by the correct certification documentation, giving main contractors, facilities managers, and building owners the compliance evidence they need for project sign-off and ongoing records.
Our BS7671 electrical testing service for AHU installations includes:
- Continuity of protective conductors
- Insulation resistance testing
- Polarity verification
- Earth fault loop impedance testing
- RCD testing where applicable
- Full schedule of test results and electrical installation certificates
AHU Controls Commissioning
AHU controls commissioning is a core specialism of Arcane Power & Controls. Our engineers have many years of experience commissioning air handling unit controls across a wide range of manufacturers’ platforms, DDC systems, and building management systems — making us one of the most experienced dedicated AHU controls commissioning teams in the UK.
Effective AHU controls commissioning goes beyond simply powering up a unit and checking it runs. We take time to fully understand the intended sequence of operation, verify every input and output, and ensure the unit performs correctly both in isolation and as part of the wider building controls system.
Our AHU controls commissioning service includes:
- Pre-commissioning inspection and controls verification
- Software upload, configuration, and sequence of operation programming
- Sensor and actuator calibration and verification
- Fan speed and airflow commissioning, including EC fan variable speed setup
- Heating, cooling, and heat recovery sequence commissioning
- Frost protection, fire shutdown, and safety interlock testing
- BMS integration and point-to-point testing
- Fault diagnosis and resolution during commissioning
- Witnessed commissioning and formal client handover
- Full commissioning records, O&M documentation, and as-fitted schedules
EC Fan Installation, Retrofit & Commissioning
EC fan installation, retrofit and commissioning is a specialist area within our AHU electrical and controls service. Whether you are installing a new AHU with EC fan technology or upgrading an existing unit from AC to EC fans, Arcane Power & Controls deliver the complete electrical installation, controls integration, and commissioning scope.
EC fan upgrades are one of the most effective ways to improve the energy efficiency of an existing air handling unit without the cost and disruption of full AHU replacement. Our EC fan commissioning ensures fans are correctly configured, responding accurately to control signals, and delivering the energy savings and performance the upgrade is designed to achieve — typically 30–50% reduction in fan energy consumption.
All EC fan electrical works are installed and tested in accordance with BS7671, with full certification issued on completion.
