BMS Installation 13+ Years hands-on BMS experience 2 hr On-site SLA for contract clients 24/7 Phones answered, every day £20M Public liability insurance BS EN 61439 Panel build standard Service overview ## BMS Installation, explainedwithout the marketing gloss. What it is A BMS installation is the full end-to-end delivery of a Building Management System: design of the control philosophy, manufacture of controls panels to BS EN 61439, containment and cabling, controller mounting, sensor and valve fit-off, software engineering, graphics build, commissioning, witness testing and formal handover. Who it's for Developers, M&E contractors, landlords, healthcare trusts and end-clients delivering new-build fit-outs, plantroom refurbishments, extensions, or wholesale replacement of legacy BMS across London and the South East. When you need it New-build projects from RIBA Stage 3 onward; refurbishments where existing controls are past economic repair; buildings changing use or occupancy; sites facing MEES, EPC or Part L compliance upgrades; and any project where the previous BMS is proprietary and locking the client in. Why professional matters A BMS installation is where every energy and comfort decision for the next fifteen years is locked in. Cutting corners on wiring practice, panel build, or software structure quietly costs the client in energy, downtime and unmaintainable code for the life of the building. The cost of ignoring it ## What happens whenthis gets left alone. Cheap installations are the most expensive line item in a building's ten-year P&L. Risks & cost escalation - Panels built to no recognised standard fail insurance and landlord audits and can force full replacement before handover. - Poor cable routing and mixed low-voltage segregation create noise, ghost alarms and years of unexplained faults. - Proprietary controllers and closed protocols lock the building owner into whichever contractor installed them; no competitive maintenance market ever forms. - Software written on-the-fly without documentation is unmaintainable within two years: every future engineer starts from zero. - Missed points, missed schedules and missed setpoints at commissioning are almost never fixed later; the building runs the wrong way for its whole first decade. Common mistakes we see - × Handing controls to the M&E contractor's cheapest sub without a specialist controls engineer owning the delivery. - × Accepting 'BMS included' on a fit-out quote without a points schedule, controls narrative or graphics scope attached. - × Skipping witness commissioning: the moment a graphics screen shows the correct number, everyone assumes the plant is actually doing it. - × Choosing a proprietary system on price without pricing in the future cost of being locked out of it. Our process ## How we deliverbms installation. 1. Step 01 Pre-design & narrative Points schedules, controls narratives and I/O counts written before a panel is quoted; see our BMS Pre-Design service. This is the document every future engineer will work from. 2. Step 02 Panel design & manufacture Panels designed in-house and built by our panel-shop partner to BS EN 61439. Full drawing pack, GA, schematics and asset labels handed over. 3. Step 03 Containment & installation Containment, wiring and terminations carried out by partner electricians holding NICEIC/NAPIT/ECA/ECS/CSCS credentials, with cabling segregation, earthing and labelling done to spec. 4. Step 04 Software & graphics engineering Controller programming, supervisor build and site graphics authored in-house: clean structure, sensible naming, documented logic. See BMS Software & Graphics. 5. Step 05 Commissioning Every point proved end-to-end: sensor to controller to graphic, and every valve, damper and interlock stroked and witnessed. Setpoints and schedules verified against the narrative. 6. Step 06 Handover O&M pack, as-built drawings, software back-ups, graphics screenshots, points list, alarm schedule and one-year workmanship warranty issued at practical completion. Outcomes you can measure ## What the right bms installationactually gives you. Open-protocol future-proofing BACnet, Modbus, KNX, LON and M-Bus: you own the system, not the installer. Any competent controls engineer can pick it up later. Panels built to BS EN 61439 The recognised standard for switchgear and controlgear assemblies. Passes landlord, insurer and building-control audits without argument. Right the first time Software written to the pre-design narrative: no on-the-fly logic, no undocumented tweaks, no 'we'll fix it in service'. One point of accountability Design, panel, software, commissioning and post-handover service all sit with one specialist, not fragmented across three contractors. One-year workmanship warranty Standard across every installation, on top of the underlying manufacturer warranties on supplied equipment. Rapid response after handover 24/7 phones and contract SLAs available immediately post-handover: the team that installed it is the team you call. Scope & specifics ## Detail thatbuyers ask about. Installations vary hugely by site type, procurement route and scope. We deliver the following commonly: Materials, methods & standards Panels: BS EN 61439. Electrical works: partner electricians (NICEIC/NAPIT/ECA/ECS/CSCS). Products supplied through our Forest Rock distributor partnership, including Tridium Niagara, Distech Controls, ABB, Mitsubishi Electric, Phoenix Contact, iSMA Controlli, Janitza, Circutor, Thermokon, Eastron and SkySpark. Cover: £20M public liability, £10M employers' liability, £10M professional indemnity. Residential vs commercial Commercial installations demand tighter tenant/landlord metering separation, formal witness commissioning and detailed handover packs. Residential installations focus more heavily on communal-plant reliability, resident comfort feedback and landlord dashboard reporting to a factor or MA. New-build commercial fit-out Cat A / Cat B office fit-outs with landlord/tenant interface, tenant sub-metering and multi-tenant graphics segregation from day one. Plantroom refurbishment Legacy controls strip-out and phased replacement while the building stays occupied, done out-of-hours where required. Healthcare & NHS installations Hospital plantroom and ward-level controls, delivered to NHS contract requirements, including 2-hour SLA readiness from go-live. Data centre controls Precision HVAC, leak detection, PDU integration and BACnet/Modbus aggregation into a unified supervisor with M&T reporting. Residential heat networks & blocks Communal boiler / heat-network controls, boosted cold-water, stair pressurisation and landlord dashboards on residential developments. Industrial & process cooling Chiller sequencing, dry-cooler control, process cooling and site-wide energy metering with alarm escalation.
