Commercial lighting controls
We keep office lighting-control systems working across London: fault-finding, programming, replacement parts and emergency-lighting upkeep on DALI, Simmtronic, Prolojik and Legrand systems, usually out of hours so your floors stay open.
What we do
- Fault-finding on DALI, M-Bus and T-Bus lighting networks
- PIR and presence detector replacement and re-addressing
- DALI driver, ballast and LED engine replacement
- Head-end PC and area controller call-outs
- New fittings added and programmed into existing systems
- Emergency lighting tests, log books, batteries and inverters
- Planned servicing and lighting-control maintenance contracts
- Early-morning, evening and weekend attendance with RAMS
Systems we work on
Drivers, ballasts, emergency inverters and addressing on DALI lighting, whoever made the system.
M-Bus and T-Bus faults, area controllers, head-end PCs and new devices, working with Simmtronic’s aftersales team when their software is needed.
PIR and wing controller faults, replacement parts and planned servicing. We do the local work on site and Prolojik can programme remotely.
Fault-finding on Legrand lighting-control panels and keypads.
Who it’s for
Reactive call-outs and planned maintenance on the lighting controls in your building.
We attend as your subcontractor, under your job numbers, with RAMS and a written report for every visit.
Lights stuck on or off, dead sensors, flickering fittings or failed emergency tests, sorted with minimum disruption.
Recent lighting-control jobs
A selection of recent commercial lighting-control work in London. Area and postcode district only – we never publish client names or addresses.
- City of London, EC3Simmtronic M-Bus fault on an office floorHalf the devices on the floor had stopped responding. We lifted the raised-floor tiles, traced the M-Bus cable to a damaged connection that was shorting the system, repaired it and tested every device. New trunking was fitted to protect the cable to the relocated head-end PC. Done on a weekend early start.
- City of London, EC3New emergency light on a Simmtronic floorAn extra emergency light added to an office floor and set up on the existing Simmtronic system, with parts and programming support from Simmtronic’s aftersales team.
- Mayfair, W1Prolojik system under a service contractA PIR that had lost communication could not be re-addressed, so we fitted a new Prolojik PIR and addressed it into the existing configuration before the office opened at 6am. Other visits covered an offline wing controller and replacement DALI drivers, ballasts and emergency inverters.

Common questions
Do you work on lighting-control systems you did not install?
Yes. Most of our lighting-control work is on existing systems in occupied offices, often years after the original installer has left.
Can you work outside office hours?
Yes. We regularly attend from 6am, in the evening or at weekends so floors are not disrupted, and we send RAMS before we arrive.
Do you work with the manufacturers?
Yes. Where a system needs the manufacturer’s software or a site visit, we work alongside teams such as Simmtronic aftersales and Prolojik, doing the on-site work ourselves.
Do you test emergency lighting?
Yes. We carry out monthly emergency lighting checks, fill in the log book and replace failed batteries, inverters and fittings.
Can you work as a subcontractor to our FM or M&E company?
Yes. Much of our commercial lighting work is for FM and M&E contractors. We work to your job references and send a written report and photos after each visit.
Which areas do you cover?
London and Essex, from our office in Chigwell. Most of our lighting-control work is in the City, Mayfair and the West End.
