Control Panel Modifications
Most of the panels we work on weren't broken when they were built. They were built for a different set of machines, a different supply, or a different scope of work, and the building has moved on. A control panel modification updates the panel to fit what the building needs today. Sometimes it's just adding circuits for new equipment. Sometimes it's a full re-engineer with new PLC logic, fresh HMI, and a complete safety overhaul.
We work alongside the building's existing M&E team to scope the modification, then design, build, and install. Every change is captured in a fresh set of drawings so the panel that comes back into service has documentation an electrician can actually use. No more chasing wires through a 15-year-old panel with a missing schematic.
Pricing ranges from £1,000 for a small contactor or terminal addition through to £5,000 for substantial PLC + HMI retrofits. We give a fixed quote against your spec so there are no surprise charges when the install starts.
Where we add safety circuits (emergency stops, light curtains, interlocks), we work to BS EN ISO 13849 to make sure the modified panel passes whoever audits it. The new and old wiring is colour-coded and labelled so the next engineer through can tell what's been changed and what hasn't.
