A closer look at how we work across the town of Swanley.
BIAV Controls is a specialist Building Management System contractor based in Swanley, on the London/Kent border. We install, service, maintain and reactively cover BMS across Swanley — the whole of the town of Swanley — including Swanley Square, White Oak, Hextable, Crockenhill and the surrounding BR8 postcode area. The business was set up to deliver a specific standard of BMS work: open protocol, transparent scoping, written documentation, and engineers who actually turn up when they said they would.
Our engineers have 13+ years of hands-on BMS experience across every major open-protocol platform — Tridium Niagara, Trend, Siemens (Desigo and Talon), Distech, Cylon and Honeywell — plus any BACnet, Modbus or LonWorks device that touches a plantroom. That platform coverage matters in Swanley because the borough's estate is mixed: modern buildings tend to be on current Tridium supervisors, mid-generation buildings run legacy Trend, and older civic and industrial stock often sits on Siemens or Cylon. One contractor comfortable across all of them saves you the pain of stitching together sub-contractors and losing accountability at the boundaries.
Every project we deliver in Swanley carries the same commercial and technical guardrails. Public liability is insured to £20M, employers' liability to £10M and professional indemnity to £10M. Control panels are designed in-house and manufactured to BS EN 61439 by our panel-shop partner. Installed workmanship carries a 1-year warranty. Pricing is quote on application — issued in writing after a real site or specification review, not pulled from a rate card — and we do not tie buildings to a proprietary supervisor.
Contract clients across London/Kent border receive a 2-hour on-site SLA and 24/7 phone cover answered by an engineer rather than an answer service. Reactive callers without a contract are prioritised within 24 hours. For Swanley specifically, Home base — engineers routinely on-site same day, so response commitments are grounded in real travel time rather than optimistic mapping. If a site sits inside the BR8 postcode range, we are already routing engineers past it most working days.
Beyond Swanley itself, our regular coverage extends across London/Kent border and into neighbouring boroughs — including Dartford, Orpington, Sevenoaks — so multi-site clients get consistent delivery, one contractor and one paper trail across their estate. If you're weighing us against a national roll-up, the practical difference is that our office is a short drive from your building, our engineers know the borough's road network and access regimes, and there is no chain of sub-contractors between the person you speak to and the person on-site.
Every BMS service we offer,delivered in Swanley.
All nine BMS services are available across the town of Swanley. Click through for full scope, process and FAQs on each.
A BMS service is a planned visit by a controls engineer who checks every sub-system on the Building Management System — sensors, actuators, dampers, valves, control loops, schedules, alarms, network health and supervisor software — then corrects setpoints, resolves faults and issues a written service report.
Read the bms service pageA 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.
Read the bms installation pageA BMS call-out is an urgent visit to diagnose and rectify a fault on the Building Management System or the plant it controls — no-heat, no-cooling, comms failure, supervisor crash, alarm storm, network dropout or safety interlock trip.
Read the bms call out pageBMS pre-design is the engineering document set that defines exactly how a Building Management System will control every piece of plant on a project: point counts, control sequences, setpoints, alarm strategy, interlocks, protocol strategy, graphics scope and commissioning checklist.
Read the bms pre-design pageA BMS project is single-point delivery of every controls scope on a construction or refurbishment programme: pre-design, panel manufacture, electrical installation, controller and sensor fit-off, software engineering, graphics, commissioning, witness testing, handover and post-handover service.
Read the bms projects pageBMS panel manufacturing is the design and build of the enclosures that house the Building Management System's controllers, contactors, protection, power supplies, network devices and terminations — engineered specifically for the plant they control and the site they will live in.
Read the bms panel manufacturing pageBMS software and graphics is the code and visual front-end that sits on top of a Building Management System: controller programming, supervisor engineering (Tridium Niagara, Distech EC-Net and equivalents), graphics build, alarm schema, trends, histories, schedules and dashboards.
Read the bms software & graphics pageBMS electrical installation is the containment, cabling, terminations and testing that physically connects a Building Management System to the plant it controls — from panel to controller to field device, plus power distribution and safety earthing.
Read the bms electrical installation pageBMS maintenance is a contracted programme of planned service visits, remote monitoring, reactive call-out and post-incident review — with defined SLAs and written reports — that keeps a Building Management System delivering the outcomes it was designed to deliver.

BMS issues we seeacross Swanley.
BMS challenges in Swanley cluster around a common theme: mixed building age, plant that has been added to over time, and control systems commissioned once and rarely revisited. Being local means we can act on those quickly and cost-effectively — no mobilisation charge for a same-day site visit.
Many BR8 commercial units have a BMS installed but no active service contract. Sensors drift out of calibration, schedules stop matching occupancy, and energy costs rise quietly. A structured PPM programme with written reports catches those issues before they become reactive call-outs.
Modern Swanley residential developments increasingly rely on communal boilers, heat-interface units or air-source heat pumps. Control strategies commissioned generically often perform badly against real occupancy — resident comfort complaints in year one are almost always a controls tuning problem, not a mechanical one.
A large share of BR8 controls estate is still running Trend IQ2/IQ3 or older Cylon outstations. Components are increasingly hard to source. We migrate control to current Tridium or Trend hardware on open-protocol supervisors without full rip-out.
Local schools and care sites have tight windows for BMS refurbishment work — half-terms, summer holidays, out-of-hours access. Being local means we can plan installations around the site's calendar rather than our travel logistics.
