Building management systems control and monitor the plant that keeps a building running: HVAC, lighting, ventilation and increasingly metering. Modern BMS software layers analytics and remote monitoring on top of legacy controls, which is how most UK buildings get value without replacing hardware.

Twinview brings live building data into a 3D digital twin for owners and operators.
Most UK owners get the fastest payback from an analytics and monitoring layer over an existing BMS, not a rip-and-replace. Full replacement is justified when controls are end-of-life, unsupported, or so proprietary that no data can be extracted at reasonable cost.
Simultaneous heating and cooling, stuck dampers, sensor drift and schedules left on 24/7 are near-universal in UK commercial stock. Automated fault detection surfaces these continuously rather than at annual service, and is usually where the first year's savings come from.
Specify open protocols and contractual access to your own point data. Proprietary controls contracts that block third-party integration are the single biggest constraint on later smart-building and net-zero projects.
| Criterion | What to check |
|---|---|
| Protocol openness | BACnet/IP or Modbus access without vendor gatekeeping. |
| FDD quality | Rules library, false-positive rate and actionability of alerts. |
| Multi-site view | Portfolio-level monitoring for estates and retail chains. |
| Controls partner | Availability of qualified UK integrators for your plant. |
| OT security | Segregation, patching and remote-access controls. |
A BMS is the control and monitoring system for a building's mechanical and electrical plant, heating, cooling, ventilation and lighting, with scheduling, alarms and, in modern systems, analytics.
A BMS controls plant. A smart building platform sits above it, combining BMS data with sensors, meters and access systems to inform decisions. They complement each other rather than compete.
Usually yes, through a gateway that exposes BACnet or Modbus points. Fully proprietary legacy systems may need a controls upgrade before any analytics layer can read the data.
Savings vary by building, but the recurring wins are corrected schedules, eliminated simultaneous heating and cooling, and earlier plant fault detection that avoids emergency call-outs. Ask vendors for measured results from comparable UK assets.
