Certifications validate your skills, differentiate you from other candidates, and often lead to higher salaries. For automation engineers, the right certifications can accelerate your career significantly. Here are the most valuable options in 2026.
Vendor-Specific Certifications
Siemens Certified Automation Engineer
Siemens offers a structured certification programme covering TIA Portal, S7-1500 PLCs, and WinCC. The exams test practical programming ability alongside theoretical knowledge. Given the dominance of Siemens in European markets, this certification carries substantial weight with UK employers.
Rockwell Automation Certifications
Rockwell offers several tiers of certification for Studio 5000, FactoryTalk, and ControlLogix platforms. These are particularly valuable if you work in industries with strong American supply chains such as automotive and food manufacturing.
EPLAN Certified Engineer
For engineers involved in electrical design and panel building, EPLAN certification demonstrates proficiency in the industry-standard CAD tool for control system documentation.
Professional Body Registrations
IET Membership and EngTech / IEng / CEng
The Institution of Engineering and Technology offers professional registration at multiple levels. Achieving Incorporated Engineer (IEng) or Chartered Engineer (CEng) status signals a high level of competence and commitment to professional standards.
ISA Certification (CCST and CAP)
The International Society of Automation offers the Certified Control Systems Technician (CCST) and Certified Automation Professional (CAP) credentials. These are internationally recognised and cover broad automation principles rather than vendor-specific tools.
CPD-Accredited Training
Continuing Professional Development accreditation ensures that training meets independently verified quality standards. CPD-accredited courses from providers like EDWartens count toward your annual CPD hours and demonstrate to employers that you are investing in structured, high-quality learning.
Key areas where CPD-accredited training adds value:
- PLC programming fundamentals and advanced techniques
- SCADA system configuration
- Industrial cybersecurity
- Functional safety (IEC 61508, IEC 62443)
- Robotics and motion control
Specialist Certifications
TUV Functional Safety Engineer
If you work with safety-critical systems, the TUV Functional Safety Engineer certification is highly regarded. It covers SIL assessment, safety PLC programming, and risk analysis methodologies.
CISCO Industrial Networking
As automation systems become increasingly networked, understanding industrial Ethernet, firewalls, and network segmentation is valuable. CISCO offers certifications specifically tailored to industrial networking environments.
CompTIA and Cybersecurity Certifications
With the convergence of IT and OT networks, certifications like CompTIA Security+ and ICS-CERT training are becoming relevant for automation engineers responsible for securing control systems.
How to Choose the Right Certification
Consider these factors when selecting certifications:
- Relevance to your current or target role — Choose certifications that match the platforms and industries you work in.
- Employer recognition — Research what certifications appear most frequently in job postings for roles you want.
- Return on investment — Some certifications require significant time and money. Prioritise those with the strongest impact on your employability.
- Maintenance requirements — Some certifications require renewal or ongoing CPD. Factor this into your planning.
Building a Certification Strategy
Rather than collecting certifications randomly, build a deliberate strategy aligned with your career goals. Start with foundational credentials, add vendor-specific skills that match your market, and layer on professional registrations as your experience grows.
The most successful automation engineers combine hands-on experience with targeted certifications, creating a compelling profile that attracts both employers and clients.
