Control Panel Repair & Fault Finding

We carry out expert repairs on all types of commercial and industrial control panels, covering everything from minor faults to complete system failures. Our engineers use advanced diagnostic tools, including thermographic scanning, to identify problems other companies miss.

When a panel fails, you need engineers who can diagnose the problem fast and fix it properly — not rotate through possibilities while your operation stands still.

Our engineers use advanced diagnostic techniques including thermographic scanning to identify faults quickly and accurately, from intermittent tripping to complete system failure.

 

We repair all types of commercial and industrial control panels including PLCs, AC & DC drives, HMI panels, soft starters, inverter drives, power supplies, motor control PCBs, and temperature controllers.

Control Panel Design & Build

When it comes to running efficient and safe electrical systems, control panels are the heart of your setup. From commercial buildings to manufacturing plants, a well-designed panel can reduce downtime, improve energy efficiency, and make maintenance simpler.

Need a panel built from scratch? We design and build bespoke control panels to BS EN 61439 for commercial and industrial applications — from simple relay-based systems to complex PLC-driven operations.

Every panel we build is designed around where your operation is going, not where it’s been. We work with trusted manufacturers including Siemens, Schneider Electric, ABB, and Hager to specify the right components for your application.

See how we designed and built a bespoke automatic transfer switch installation for a Central London newspaper print facility.

Control Panel Installation

A well-built panel needs a well-executed installation. Our engineers carry out on-site installation and commissioning of new and replacement control panels, ensuring everything is tested, documented, and compliant before handover.

We work alongside other contractors and directly with facilities managers to integrate new panels into existing electrical infrastructure with minimal disruption to your operations.

Control Panel Safety Checks

Regular safety checks keep your panels compliant, your insurance valid, and your operation protected. Our safety inspections cover electrical and functional testing of PLCs, I/O cards, and drives, thermographic scanning for overheating components, verification of safety interlocks and emergency stops, and detailed reporting for audit and insurance purposes.

Call 020 8455 9020 to book a safety check.

Frequently Asked Questions

What types of control panels do you repair?

We repair all types of commercial and industrial control panels — PLC panels, motor control centres, drive panels, power distribution panels, BMS control panels, and relay-based systems. If it controls something, we can diagnose and repair it.

Yes. We regularly work on older relay-based and legacy PLC systems where parts are difficult to source. Our engineers have 30 years of experience across a wide range of manufacturers and panel types.

We work with all major manufacturers including Siemens, Schneider Electric, ABB, Honeywell, Hager, and Loxone. We are a Loxone certified partner for smart building automation.

We aim to respond within the same business day. For urgent situations call us directly on 020 8455 9020.

Most repair and fault finding work is carried out on-site to minimise your downtime. Where a panel or component needs to leave site for specialist repair we will advise you clearly and agree the fastest route to resolution.

Yes. We design and build bespoke replacement panels to BS EN 61439, including like-for-like replacements for obsolete systems and upgraded panels with modern components and improved functionality.

Yes. Every job comes with full documentation — test results, work carried out, component specifications, and recommendations for ongoing maintenance.
