It has been the philosophy since 1989. Air blown fibre, optical and copper cabling — designed, installed, tested and certified by directly employed, security-cleared engineers. From listed buildings to new data centres.
Design, supply, installation and commissioning — one directly employed team, from first survey to certified handover.
Microduct networks with fibre blown in only when needed — no dead fibre, hardly any splicing, and new links the same day.
Optical fibre and structured copper infrastructures, designed and installed to manufacturer specification — with the warranty to match.
Data and server cabinets, shelving, cable management and containment — specified for the room, supplied, built and sited.
Length, wiremap, NEXT and return loss on every link — plus FIP optical inspection that sees defects down to one micron.
Schematics, patching schedules and health checks brought up to date — problems identified, recommendations made, upgrades delivered.
NICEIC-approved electricians — power, lighting, containment, access control and BMS, from working offices to nationwide retail.
Our engineers hold the security clearance required for police estates and UK airports — built over decades of programmes for the Metropolitan Police Service, from HQ buildings to Holmes I & II and the Met-wide VoIP upgrade. Everyone on site is ours: directly employed, manufacturer accredited, and trained well beyond the minimum.
