BMS Upgrades & Retrofits in Buckinghamshire
Alpha Controls upgrades and retrofits building management systems across Buckinghamshire — migrating legacy platforms to current supported architectures, extending system capabilities, and improving energy performance without the disruption of a full replacement. We work with Trend 963 end-of-life migrations, Honeywell Excel upgrades, Satchwell replacements, and Johnson Controls legacy systems.
The case for upgrading a legacy BMS is usually made by one of three factors: the platform has reached end of support (Trend 963 reached end of life in January 2025 — buildings still running 963 have no security patch path), hardware replacements are becoming difficult to source, or the building's energy performance requirements can no longer be met by the existing control strategy.
Our upgrade approach for Buckinghamshire buildings prioritises retaining existing IQ field controllers and field wiring where they remain serviceable — the cost saving versus full replacement on a large building can be £30,000 to £80,000. We assess each system individually and provide an honest view of what can be retained, what needs replacing, and what the realistic payback period looks like for the capital investment.

Get in TouchFrequently Asked Questions
What legacy BMS platforms can you upgrade in Buckinghamshire?
We upgrade Trend 963, Honeywell Excel, Satchwell, Johnson Controls Metasys, and older Siemens platforms. For Trend upgrades, we migrate to IQVISION as the supervisory front end, retaining existing IQ field controllers wherever their condition justifies it.
Can the upgrade be done in phases to spread the cost?
Yes. We regularly phase BMS upgrades across financial years or building zones — upgrading the supervisory platform first, then field controllers floor by floor or plant by plant. We design the phasing sequence so each phase delivers a fully functional system.
How disruptive is a BMS upgrade for building occupants?
Most upgrade work in Buckinghamshire buildings is carried out during normal working hours with minimal occupant disruption. Plant downtime is typically limited to individual changeover points — usually minutes per zone — rather than extended shut-downs. We agree the works programme with the FM team before starting.
