What Sequentec does
Sequentec Ltd is a privately held, founder-led engineering consultancy headquartered in Loanhead, Midlothian (near Edinburgh), Scotland, founded in 2015 by Charlie Westerling. The company designs and manufactures bespoke real-time control, secure communication, and electrical systems for clients developing marine renewable energy devices (wave and tidal power converters), small wind energy systems, and industrial controls applications. Sequentec operates with a team of approximately seven people and is positioned as a specialist supplier to a narrow set of OEMs and device developers, particularly in the UK marine renewables sector.
The company's core offerings center on real-time distributed control systems built using off-the-shelf industrial automation components combined with custom electronics. Underlying technology includes Ethernet Powerlink networking, PLC/IO integration, embedded microcontrollers, and safety PLCs, with software developed primarily in C and Python. Products and services span four main areas: real-time control systems for offshore and subsea deployment; secure communication systems enabling remote data transfer and automated alarm handling; bespoke electrical panel design and manufacturing; and prototype electronics and test systems, including custom PCB design using open-source CAD tools. The company is a recognized B&R Value Provider (B&R Industrial Automation / ABB Group), placing it within a select global community of automation experts.
Sequentec's business model is B2B project-based: clients engage directly via the company website or email, projects are bespoke, and pricing is quote-based and project-specific. Revenue is generated through a mix of professional engineering services (consulting, design, integration, commissioning, maintenance) and hardware sales (custom panels, control units, prototype boards). The company serves both prototype-stage developers and established designs, and provides on-site installation, commissioning, and maintenance support across the UK. Distribution is exclusively direct; no resellers or third-party channels are used. The company has no disclosed institutional investors or external funding and operates as an independent consultancy.

Sequentec competitors and assessment
Company assessmentBroad incumbents
- Siemens: Global industrial automation, control systems, and digital industries incumbent. Competes broadly with Sequentec in industrial control and SCADA and overlaps in renewable-energy control offerings, though Siemens operates at much larger scale.
- Schneider Electric: Global industrial automation and energy management incumbent with EcoStruxure platform. Comparable as a broad industrial control provider whose products and integrator ecosystem overlap with Sequentec's industrial controls customer base.
- Rockwell Automation: Global industrial automation incumbent with Allen-Bradley and Logix control platforms. Comparable as a broad incumbent offering overlapping control-system functionality to Sequentec's industrial customer segments.
- ABB: Global industrial automation and electrification incumbent and parent of B&R. Sequentec is a B&R Value Provider within the ABB ecosystem, so ABB is a partner/incumbent whose broader automation portfolio competes with and routes demand to Sequentec.
Direct peers
- Boulting Technology: UK industrial automation and electrical engineering firm delivering bespoke control panels, PLC, and SCADA systems. Comparable as a UK-based industrial control systems integrator serving similar end-customers.
- Wood Thilsted: UK-based offshore wind engineering consultancy providing structural and electrical systems design to wind farm developers. Comparable as a bespoke offshore-renewables engineering services firm, though more focused on fixed-bottom and floating wind.
- Capula: UK industrial automation systems integrator specialising in control, SCADA, and cyber-secure solutions for critical infrastructure. Comparable in providing bespoke real-time control systems integration with overlapping UK industrial customer base.
- Quoceant: Aberdeen-based engineering consultancy providing analysis, design, and control support to marine renewable energy developers. Directly comparable in size, geography, and marine-renewables control-systems focus to Sequentec.
- BMT Group: UK-headquartered marine engineering consultancy offering design, naval architecture, and control-systems services to offshore energy clients. Comparable as a marine/offshore engineering services peer serving similar customer segments.
Emerging players
- Beckhoff Automation: German automation specialist offering PC-based control and EtherCAT real-time networking. Comparable to Sequentec's real-time control and Ethernet Powerlink stack from a technology/architecture perspective, though Beckhoff is a product company while Sequentec is a services integrator.
