You can become a PLC engineer in the UK without prior automation experience in six to nine months if you commit to a structured plan. The shortest credible path is: complete a CPD accredited intensive course (5 days), build a portfolio project (2 to 4 weeks), apply to 30 to 60 junior PLC and automation engineer roles (4 to 8 weeks), and start work within 6 weeks of your first offer. Total investment: roughly £2,000 to £2,500 for training and £500 to £1,000 for project hardware. First-year earnings: £30,000 to £38,000, recovering your investment within 6 months of starting.
This is the playbook we've used to place over 30,000 engineers globally and several hundred career changers into UK roles specifically.
Who can become a PLC engineer in the UK?
The successful career-change candidates we've placed share a few traits, not a specific background:
- Genuinely enjoy how machines work (you took things apart as a kid, or you've built a PC, or you mess with smart home automation)
- Comfortable with simple maths (you can rearrange algebraic equations; calculus not required)
- Can read a wiring diagram or are willing to learn (this is more about patience than IQ)
- Patient enough to debug a problem for hours without throwing the laptop
Backgrounds we've successfully placed: ex-Forces engineers (REME, RAF aircraft mechanics), recent STEM graduates, maintenance electricians, mechanical engineers, qualified electricians (NICEIC), facilities managers, IT support engineers, and even a former chef who'd spent ten years tinkering with restaurant kitchen equipment. The common thread isn't background; it's curiosity about how things work.
The 6-month plan
Month 1: Foundation reading (~10 hours, £0)
Before paying for training, build basic vocabulary so you get value from day one of the course:
- Read RealPars' free PLC basics articles (realpars.com)
- Watch Tim Wilborne's YouTube series on Siemens TIA Portal (free)
- Download the Siemens TIA Portal V18 trial (works 21 days; you can extend)
- Read the What is a PLC article on our blog
- Skim our PLC vs SCADA explainer
This isn't training. It's vocabulary so the trainer doesn't have to spend day one explaining terms.
Month 2: Structured training (5 days, £1,495–£2,700)
Pick a CPD accredited intensive 5-day course. The right course covers:
- Ladder logic programming (about 40% of course time)
- Function block diagrams and structured text (about 15%)
- HMI configuration (about 15%)
- SCADA introduction (about 15%)
- Networking, IP addressing, hardware (about 15%)
Avoid courses that are 80% slides. By end of week one you should have programmed a working "small project" yourself, like a traffic light controller or simple conveyor sequence.
Our Professional Automation Engineering Module follows this exact structure, plus 15 hours of recorded sessions you can re-watch indefinitely. Other quality providers exist, compared in our UK PLC training provider ranking.
Month 3: Portfolio project (3 to 4 weeks, £200–£600)
This is the step most self-taught engineers skip and it's the single biggest reason they don't get interviews.
Buy or build hardware. Cheapest credible option:
- A Siemens LOGO! 8 starter kit (£300 to £450) — small but real PLC
- OR a budget Arduino-based industrial controller (£150 to £250) — not a "real" PLC but enough to demonstrate logic skill
- OR continue with TIA Portal simulation if no budget for hardware
Build ONE project end to end:
- Multi-zone traffic light controller with pedestrian crossings
- Small batch process simulator (mixing tank with three ingredients)
- Conveyor sorting system with photo eye and reject paddle
- Lift control logic (request buttons on three floors, door interlocks)
Document it with:
- A 3-minute video showing it working
- A written description of the logic
- A wiring diagram (use Eplan trial, AutoCAD Electrical, or draw it in Visio)
- The exported PLC program file
This portfolio is what gets you past the CV stage.
Month 4: CV, LinkedIn, applications (4 to 6 weeks)
Your CV needs to lead with:
- Your training and accreditation (course name, provider, dates, CPD points)
- Your portfolio project (one sentence with link to video)
- The specific PLCs you've used (Siemens S7-1200, TIA Portal V18, etc.)
- Any transferable engineering experience (apprenticeship, electrical work, IT support)
- Education (school leavers' qualifications + any further education)
Apply to roles titled:
- Junior PLC Engineer
- Junior Controls Engineer
- Trainee Automation Engineer
- Apprentice Automation Engineer (often available even to career changers in their 30s and 40s through the apprenticeship levy)
- Maintenance Technician (Automation Focus)
- Graduate Controls Engineer (if you have any engineering degree)
Volume matters. Apply to 30 to 60 roles minimum across LinkedIn, Indeed, Reed, CV Library, TotalJobs, and Engineerjobs.co.uk. Expect 5 to 15% reply rate, 30 to 50% interview-to-offer conversion if your portfolio is good.
Month 5–6: Interview, offer, start
The typical UK junior PLC engineer interview is one technical phone screen, one in-person technical interview with a small practical task, and one final culture/site visit. Total elapsed time from first contact to offer: 3 to 6 weeks.
What to expect at technical interview:
- Read this ladder rung and explain what it does
- Sketch ladder logic for a simple sequence (start/stop with safety door interlock)
- Explain the difference between a PLC and a microcontroller (or PLC and SCADA)
- Trace a fault on this schematic
- Talk through your portfolio project
The portfolio talk is often the deciding factor.
The visa route for international engineers
If you're outside the UK with engineering background, the route is:
- Complete a UKRLP-registered, CPD accredited PLC training programme (online live or in-person)
- Build your portfolio
- Apply specifically to sponsor-licensed employers (full list at gov.uk; over 50,000 companies)
- Negotiate a Skilled Worker visa offer; minimum salary £41,700 for 2026
- End to end: typically 3 to 6 months from training completion to start date in UK
We support our international students with sponsor company introductions where we have relationships. See our placements page for typical international placement examples.
The funded route via apprenticeship
If you're employed in any UK manufacturing or engineering company, you may be eligible for an apprenticeship that includes PLC training, fully funded by the apprenticeship levy:
- Level 3 Maintenance and Operations Engineering Technician — 3 years, includes PLC modules
- Level 4 Automation and Controls Engineering Technician — 2 to 3 years, deeper PLC focus
- Level 6 Control Systems Engineer (Degree Apprenticeship) — 4 years, equivalent to a degree
Ask your employer's HR or learning and development team. Apprenticeships are open to any age, not just school leavers, and the levy pays 95–100% of training costs.
Common mistakes career changers make
Based on observing thousands of applicants, the mistakes that cost people offers:
- Skipping the portfolio. Most candidates have a certificate but no demonstration of skill. Hiring managers can't tell from a CV whether you actually can program; the portfolio answers that.
- Applying only to senior PLC engineer roles. A junior engineer role at £30k pays back your training in months. A senior role at £55k won't hire someone with 6 months of experience.
- Underselling transferable skills. A 10-year electrician who's just retrained in PLC programming is far more valuable than a fresh graduate. Lead with the experience.
- Sending generic CVs. Tailor each application to mention the specific PLC platform the employer uses (look at their LinkedIn engineering posts or careers page).
- Giving up after 10 applications. First-job junior PLC search takes 30 to 60 applications. Volume wins.
