What BMS Maintenance Covers
A proper BMS service contract is not just an annual visit and a certificate. It is the difference between a system that drifts into inefficiency and one that earns its keep year-round.
Planned Preventative Maintenance (PPM)
Scheduled visits aligned to CIBSE TM39 guidance — inspecting controllers, sensors, actuators, and communication networks before they cause problems. Setpoints validated, strategies checked, drift documented before it becomes a fault.
Reactive Maintenance
When something goes wrong, you need someone who knows the system — not a call centre. P1 critical faults carry a 4-hour attendance target on Enhanced contracts, and remote dial-in lets us diagnose faults before we leave the office.
Remote Monitoring
Continuous monitoring via secure remote access. Alarms routed directly to our engineers. Energy anomalies flagged before they appear on your utility bill.
Annual Condition Reports
Full documented assessment against BS EN 15232 efficiency classes. We will tell you honestly where you sit and what moving to Class B would save you.
Technology We Support
Why Kent Buildings Are Different
Kent has a particular mix of building stock that most national contractors do not understand properly.
The logistics and industrial corridor along the A2/M2 — Dartford, Gravesend, Sittingbourne — runs large warehouse and manufacturing facilities, many built in the 1990s on original Trend 963 or Siemens VISONIK/DESIGO platforms. These systems are capable of running for another decade with proper maintenance. They need someone who can read a Trend SQBMS database and knows what a healthy supervisory network looks like.
NHS and education estates across Medway, Maidstone, and Ashford typically operate multi-site BMS environments with mixed controller vintages, constrained access windows, and procurement frameworks that favour local contractors who can respond fast.
Commercial offices in Sevenoaks, Tunbridge Wells, and Canterbury often carry original Siemens or Trend installations from 1990s–2000s developments. Energy performance is under increasing scrutiny from landlords chasing EPC improvements and tenants scrutinising service charges.

Frequently Asked Questions — BMS Maintenance Kent
What BMS systems does Alpha Controls maintain in Kent?
We maintain Trend IQ2, IQ3, and IQ4 controllers, Trend 963 supervisor, Distech ECB, ECL, and ECLYPSE series, Siemens DESIGO PX and PXC, and legacy proprietary systems across Kent. We also support mixed-brand estates where multiple platforms communicate across the same network.
How quickly can Alpha Controls respond to a BMS fault in Kent?
For a P1 critical fault — total loss of heating, cooling or ventilation to an occupied area — an engineer acknowledges within one hour. The attendance target is 4 hours on an Enhanced contract and the next working day on Standard; without a contract it is reasonable endeavours. Callouts start at £650 for the first four hours on a weekday, and travel is included within 40 miles of Gravesend. Remote diagnostics mean we can often start fault investigation before an engineer departs.
Is Alpha Controls suitable for NHS or education BMS maintenance in Kent?
Yes. We hold SafeContractor approval and are members of the BCIA (Building Controls Industry Association). We are familiar with the access restrictions, permit-to-work requirements, and phased commissioning processes that apply to NHS and education estates. We have worked weekend-only and sectored working arrangements on sites with occupancy constraints.
Can you maintain an ageing Trend IQ3 system without replacing it?
Yes. IQ3 is discontinued for new installations but fully serviceable. Alpha Controls provides ongoing maintenance, fault diagnosis, and programming support for IQ3 sites. If hardware is failing, we can replace like-for-like where parts are available, or plan a managed migration to IQ4 without disrupting the rest of the installation.
What does a BS EN 15232 condition report include?
Our annual BS EN 15232 condition report documents where your BMS sits against the four building automation efficiency classes — D through A. It identifies the control functions currently active, what is missing or misconfigured, and what the energy saving potential would be from moving up a class. Suitable for EPC assessors, sustainability audits, and landlord due diligence.
