BMS Commissioning in Berkshire
Alpha Controls carries out BMS commissioning across Berkshire for new installations, systems handed over incomplete by other contractors, and existing buildings where performance has degraded since original handover. We work to CIBSE Commissioning Code M and BSRIA BG8, providing a documented, point-by-point test record rather than a verbal sign-off.
Most BMS performance problems are commissioning problems. Setpoints copied from previous projects, sensors that were never verified against reference instruments, control sequences tested in an empty building that fail under real occupancy — these are the underlying causes of comfort complaints and energy waste that persist for years after a building opens. Commissioning done properly prevents all of them.
For buildings in Berkshire that are already occupied, we carry out recommissioning against the original design intent — reviewing the as-built I/O schedule, verifying every sensor, re-testing control sequences, and producing a commissioning report that documents actual performance. Where the gap between design and actual performance is significant, recommissioning typically reduces energy consumption and resolves comfort issues without any hardware replacement.
What We Cover
- Point-by-point I/O verification before functional testing begins
- Sensor calibration against calibrated reference instruments
- Functional testing of all control sequences under simulated conditions
- Alarm logic and interlock testing — including fire alarm integration
- Integration testing across linked systems
- Signed commissioning report with as-built performance data
- Building log book production per CIBSE TM31
- Post-handover performance monitoring per BSRIA Soft Landings
Areas We Cover in Berkshire
Reading and the M4 corridor between Slough and Newbury host a concentration of technology and financial services offices that require high-reliability BMS and environmental controls.

Get in TouchFrequently Asked Questions
Can you commission a BMS that another contractor installed in Berkshire?
Yes. We regularly commission systems we didn't install. We start with an I/O audit to verify every point against its physical wiring, then carry out full functional testing. We provide a signed test record confirming which sequences pass and which require remediation.
What's included in a commissioning report?
A commissioning report should include: a point-by-point test record for every device on the I/O schedule, sensor calibration data with reference instrument readings, control sequence test results for every operating mode, and a summary of any outstanding items requiring remediation. We provide all of these.
How long does BMS commissioning take?
For a typical commercial floor of FCU zones: one to two days per floor. For an AHU and associated plantroom: one to three days per major plant item for a thorough functional test. Complex integration testing adds time depending on the number of linked systems.
