Based in Swanley on the London/Kent border: 20–35 minutes off-peak from Swanley. We work across Sevenoaks town, Riverhead, Otford, Kemsing and the wider Sevenoaks, Kent on installation, service, maintenance and reactive call-out. We cover Sevenoaks Sevenoaks town and the surrounding TN13, TN14 and TN15 postcodes, including Riverhead, Otford, Kemsing, Seal, Weald, Underriver and the villages along the A25 and A21 corridors. Response times Sevenoaks is 20–35 minutes off-peak from our Swanley office. Contract clients receive a 2-hour on-site SLA; attendance across TN13/TN14 is normally well inside it. 24/7 phones answered by a controls engineer.

On the ground in Sevenoaks ## A closer look at how we work across Sevenoaks, Kent. 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 Sevenoaks, the whole of Sevenoaks, Kent, including Sevenoaks town, Riverhead, Otford, Kemsing and the surrounding TN13, TN14, TN15 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 Sevenoaks 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 Sevenoaks 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 Kent 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 Sevenoaks specifically, 20–35 minutes off-peak from Swanley, so response commitments are grounded in real travel time rather than optimistic mapping. If a site sits inside the TN13, TN14, TN15 postcode range, we are already routing engineers past it most working days. Beyond Sevenoaks itself, our regular coverage extends across Kent and into neighbouring boroughs, including Swanley, Orpington, Dartford, 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.

View service ](/services/bms-energy-optimisation) Why choose us in Sevenoaks ## Concrete reasons,not marketing lines. Every claim on this page is drawn from things we can evidence: our insurances, our SLAs, our warranty terms and the standards our panels and partner electricians work to. Local Kent presence Sevenoaks is inside our daily working area: under 30 minutes from Swanley in most conditions. That means realistic PPM travel costs and genuine reactive response, not motorway drives from the wrong side of London. Comfortable with independent schools and heritage sites Sevenoaks has a concentration of independent schools and listed property. Both need engineers who can plan around term dates, listed-consent constraints and out-of-hours access, and produce the paperwork that supports future works. Fully insured and documented £20M public liability, £10M employers' liability, £10M professional indemnity. Panels built to BS EN 61439. Written service reports every visit. 1-year workmanship warranty on installations. Local problems, honestly ## BMS issues we seeacross Sevenoaks. Sevenoaks BMS work is defined less by scale than by constraint: heritage fabric, independent-school term calendars, hospitality operating hours and rural connectivity all shape what a workable controls solution looks like. Listed-building controls retrofits Heritage property in and around Sevenoaks restricts where sensors, cabling and containment can go. We route around fabric, not through it, and we produce the drawings and narratives that support future listed-consent applications. Independent-school term-window works Full BMS refits at Sevenoaks independent schools have to fit inside Easter, summer or Christmas holidays. We plan mobilisation, commissioning and witness testing to hit the return-of-term date, not our own convenience. Hotel and hospitality reliability Local hotels and country-house venues need out-of-hours reliability and tight hot-water and comfort control. We service and reactively cover those sites under formal SLAs, not on best-endeavours. Rural site connectivity for remote monitoring Not every Sevenoaks site has enterprise-grade connectivity. We install remote-monitoring solutions that work on limited bandwidth or 4G, so problems are diagnosed remotely rather than driving to site each time. Our process ## How we deliver BMS workacross Sevenoaks. 1.
