What The RDM Group does
The RDM Group is a UK-based, family-owned industrial control systems and electrical installations group headquartered in Honley, Holmfirth, West Yorkshire. It operates through two complementary subsidiaries: RDM Controls Ltd, which designs and manufactures electrical control systems for machinery, and RDM Installations Ltd, which delivers the on-site electrical contracting, hazardous-area work, testing and commissioning. The group serves industrial customers across multiple verticals — logistics and distribution, process automation (including oil, gas, chemicals, food, pharmaceutical and water treatment), dust extraction, and bespoke machinery manufacturing — with named enterprise references including Tesco, Sainsbury's, Morrisons, Asda, Next, B&Q, IKEA, Boots and Aldi.
Its core technology centres on PLC-based automation, HMI interfaces, variable speed drives, and bespoke control panel hardware. Proprietary products include the 4100 Combination Control Panel and the Digital Limit Module for loading-bay applications, alongside Zone 20/21/22-certified hazardous-area panels and standard D.O.L starters. RDM engineers programme across all major PLC platforms (Siemens, Allen Bradley, Mitsubishi, Omron, Telemecanique) and integrate third-party hardware such as Invertek drives and Traka access-control devices. A library of 250+ design sequences for loading-bay control systems compresses lead time on repeat logistics work.
The business model is a mix of one-time project sales (custom panels from ~£50 to ~£20,000 per unit), professional services for electrical installation and commissioning, and a growing annuity stream from service and breakdown contracts. All distribution is direct, via enterprise and SME field sales, telephone (01484 660503) and website enquiries. The group is differentiated by CompEx-certified hazardous-area engineers, a dense stack of UK compliance credentials (CHAS, SafeContractor, NICEIC, ECA, ECS, Alcumus), and a 3-year parts-and-labour warranty extendable to 5 years under a service contract.

The RDM Group competitors and assessment
Company assessmentDirect peers
- Control Techniques (Nidec): UK-headquartered drives and motor-control specialist whose products RDM integrates; closely comparable on variable speed drives and industrial automation focus.
- Boulting Technology Services: UK-based control systems integrator and panel builder with a similar mix of bespoke PLC panels, hazardous-area work and electrical installation services for industrial customers. Comparable mid-market UK delivery model.
- InControl Systems: UK-based automation systems integrator delivering PLC, SCADA and bespoke control panels to industrial clients — directly comparable scope and customer type to RDM Controls.
- CP Automation: UK specialist in variable speed drives, motor control and industrial automation service — directly overlapping with RDM's VSD, inverter drive and PLC programming offering.
- Logical Solutions & Applications: UK automation and control systems provider offering PLC programming, panel building and site installation services comparable to RDM's combined design-and-install model.
Broad incumbents
- ABB (UK Industrial Automation): Global automation and drives supplier with overlapping PLC, motor control and hazardous-area capabilities; RDM is a potential partner/integrator for ABB products.
- Rockwell Automation (Allen Bradley): Owner of the Allen Bradley PLC platform which RDM explicitly supports; competes broadly in industrial automation panels and integration.
- Schneider Electric (UK): Global industrial automation incumbent whose PLC, VSD and motor-control portfolios overlap directly with RDM's offering, but at vastly greater scale and breadth.
- Siemens UK (Digital Industries): Major automation OEM whose SIMATIC PLCs and SINAMICS drives are explicitly supported by RDM; competes for the same industrial control panel and integration spend.
Others
- Rittal Limited (UK): Enclosure and panel-building supplier to industrial control system builders — a key upstream supplier/adjacent ecosystem player rather than a direct competitor.
