What Capula does

Capula is a UK-headquartered industrial Operational Technology (OT) systems integrator, founded in 1970 and privately held since its July 2017 acquisition by Dalkia and EDF. The company designs, builds, integrates and supports automation, control and protection systems — including SCADA, DCS, PLC/RTU solutions, substation automation, functional safety systems and bespoke control panels — for operators of critical national infrastructure across nuclear, power generation, energy networks, renewables, water, and industrial manufacturing. Capula operates a 1,480m² in-house panel manufacturing facility in Staffordshire capable of producing 840 panels per annum, complemented by offices in Whitehaven, Reading, Malton and Glasgow.

Its technology portfolio is built around proprietary frameworks including The Technology Bridge (OT/IT integration methodology), the REACH consultancy methodology, the Capula Consultancy Framework (CCF), and the Five Domains of Industrial Cyber Resilience framework aligned with IEC 62443 and NIS. Capula holds functional safety accreditation to CASS/IEC 61508 up to SIL3, RCC-E QC Grade 1, ISO 9001, ISO 14001 and TickIT plus, and is endorsed by AVEVA, Schneider Electric, Siemens, Rockwell Automation, PTC and InfluxData.

Commercially, Capula operates a B2B engineering services model with revenue generated through project-based professional services contracts, panel build-to-print manufacturing, and recurring through-life support/managed services. Customer acquisition is driven by long-term framework agreements and embedded strategic supplier relationships, with the go-to-market led by engineering credibility and regulatory compliance rather than volume distribution. Named anchor customers include National Grid, Sellafield, EDF, Severn Trent and Hinkley Point C, with multi-decade continuous supplier relationships underpinning a visible long-duration revenue pipeline.
