To work in the UK on a Skilled Worker visa you need a confirmed job offer from a Home Office-approved sponsor, an eligible occupation and a salary of at least the higher of £41,700 or the job's going rate, according to gov.uk on 21 October 2026. For PLC work, that means experienced controls and automation engineers are the realistic sponsored hires, while many trainee roles pay below the thresholds.
What are the Skilled Worker visa rules for engineers?
gov.uk sets four basic conditions: a job with an approved UK employer, a certificate of sponsorship (CoS) from that employer, an eligible occupation, and a minimum salary. You must have a confirmed job offer before you apply. The table summarises what the official pages say.
| Requirement | What gov.uk says (21 October 2026) |
|---|---|
| Employer | Must be a Home Office-approved sponsor; unlicensed employers can apply, at £611 (small) or £1,682 (medium and large), taking around 8 weeks |
| Minimum salary | The highest of £41,700 a year and the going rate for the occupation code |
| Lower salary options | At least £33,400 and 70% of the going rate if you are under 26, a recent graduate or in professional training; limits on length of stay apply |
| Skill level | Codes are listed as higher skilled or medium skilled; medium-skilled jobs qualify only if on the immigration salary list or temporary shortage list |
| English | Usually B2: UK school qualification, a degree taught in English or an approved test |
| Time limit | Up to 5 years before extending; may lead to settlement |
Which occupation codes cover PLC and controls work?
There is no code called "PLC engineer", and the code depends on the duties, which your employer decides when it assigns the CoS. gov.uk tells you to ask your employer for the four-digit code or search the CASCOT tool, and warns that not every job title is listed. These codes are commonly relevant to controls work; the figures come from gov.uk's tables.
| Code | Job type | Category on gov.uk | Standard going rate | Effective minimum (higher of rate and £41,700) |
|---|---|---|---|---|
| 2125 | Production and process engineers, including control and instrumentation engineers | Higher skilled | £45,000 | £45,000 |
| 2129 | Engineering professionals n.e.c., including mechatronic and robotics engineers | Higher skilled | £46,100 | £46,100 |
| 2123 | Electrical engineers | Higher skilled | £58,700 | £58,700 |
| 3113 | Engineering technicians | Medium skilled (on temporary shortage list) | £42,500 | £42,500 |
| 3112 | Electrical and electronics technicians | Medium skilled (on temporary shortage list) | £39,300 | £41,700 |
The temporary shortage list page I read (listing 3112, 3113 and electricians under 5241) says medium-skilled jobs on it can apply for entry clearance. Lists change, so confirm that your code is still on it. Do not assume an advert's job title maps to a code; ask the employer which code it will use.
Can a trainee PLC job be sponsored?
Rarely. The lowest salary gov.uk allows on this route, outside special cases, is £33,400. Reed's trainee PLC listings on 21 October 2026 included a Graduate Control Systems Engineer (training on PLC programming) at £25,000 to £27,000 and a Graduate/Junior Engineer at £27,000 to £30,000, both below that floor. Junior roles at £40,000 to £50,000 do exist, but they tend to expect existing skills.
Salaried experienced roles look different. According to ITJobsWatch, permanent PLC Engineer adverts in the six months to 21 October 2026 had a median of £60,000, with a 10th percentile of £42,500 and 144 adverts (79 a year earlier). That sample is small and IT-leaning, but it shows why sponsorship is more plausible at mid level. Our PLC engineer salary guide has more detail.

How do you search for sponsoring employers?
Start with the official list. gov.uk publishes a register of licensed sponsors (Worker and Temporary Worker) showing each organisation's licence category and rating; it was updated on 21 October 2026. Only a licensed employer can issue a CoS, so check an employer's name before you invest time.
Then search sensibly:
- Shortlist engineering employers on the register in sectors that use PLCs, such as manufacturing, food and water.
- Read adverts for explicit wording on sponsorship. Reed has a "visa sponsorship" filter, but a search page I opened showed 77 results while none of the summaries I read stated sponsorship, so check each advert.
- Ask recruiters two direct questions: is this role eligible for sponsorship under current rules, and which occupation code will be used?
- Treat any offer to sell you a job or a certificate of sponsorship as a red flag.
What about international students in the UK?
If you have studied in the UK, the Graduate visa may bridge the gap. gov.uk says it lasts 2 years if you apply on or before 31 December 2026 and 18 months if you apply on or after 1 January 2027, and it costs £937 plus the healthcare surcharge. You can switch from it to a Skilled Worker visa, and gov.uk's lower-salary option allows 70% of the going rate (at least £33,400) for recent graduates, with a maximum stay of 4 years in total.
What does the visa cost, and what else should you know?
Budget for more than the fee. gov.uk lists a standard application fee of £819 for up to 3 years or £1,618 for longer when applying from outside the UK, a healthcare surcharge usually £1,035 per year, and £1,270 in savings held for 28 days unless exempt or your employer certifies maintenance. A decision usually takes about 3 weeks from outside the UK, and you must apply within 3 months of getting your CoS. Jobs on the immigration salary list pay lower fees.
Skills demand is real but is not a visa rule. The IET's 2025 skills survey, run with YouGov among 1,316 managers between February and March 2025, found 76% of engineering employers struggle to recruit for key roles and 30% lack automation skills. Demand does not oblige any employer to sponsor you.
What is the sequence from job offer to visa?
The order matters, because you cannot apply until the employer has done its part. Based on gov.uk's Skilled Worker pages, the usual sequence is:
- Find an approved sponsor that employs controls or automation engineers.
- Receive a confirmed job offer. gov.uk says you must have this before you apply.
- Employer issues a certificate of sponsorship, an electronic record with a reference number, stating the role and its occupation code.
- You apply online within 3 months of getting the CoS, prove your identity and English, and pay the fee and healthcare surcharge.
- Decision. gov.uk says decisions usually take about 3 weeks from outside the UK, and you can apply up to 3 months before your start date.
Part-time or reduced-hours roles need care. gov.uk states that the annual salary figures are based on a 37.5-hour week and must be pro-rated for other working patterns, so check the maths with your employer.
What mistakes should you avoid?
Most problems come from assumptions made before checking. A few to watch:
- Assuming "PLC engineer" means one occupation code. The employer assigns the code, and the code decides both eligibility and the going rate.
- Comparing your offer only with £41,700. The going rate for the code may be higher, as with 2123 at £58,700.
- Applying to employers not on the register. An unlicensed employer cannot issue a CoS until it has a licence, which gov.uk says takes around 8 weeks to process.
- Treating a visa-sponsorship filter or advert wording as a promise. Confirm in writing before resigning from a current job or paying costs.
- Relying on social media advice. Rules, thresholds and lists change, and out-of-date posts circulate for years. Use gov.uk.
What if your occupation is not eligible?
Then look at other routes rather than forcing the Skilled Worker one. gov.uk's overview says that if you are not eligible for a Skilled Worker visa, you may be eligible for another type of visa to work in the UK. Which route fits depends on your nationality, age, qualifications and family situation, which is exactly why a regulated immigration adviser is worth paying for before you commit to a move.
What you can do meanwhile is strengthen the part you control: skills evidence, a UK-format CV and the ability to explain real projects. Our guide to the automation engineer career path shows how roles progress, which helps you target jobs at the level where sponsorship is realistic.
How EDWartens can help
A short course is not an immigration route, and EDWartens does not sponsor visas or guarantee jobs. The Professional Module is a live online course (Siemens TIA Portal, PLC, HMI and WinCC SCADA) that you can take from anywhere, with a verifiable CPD certificate and help preparing a UK-style CV. It costs £2,140 + VAT (£2,568), with a £100 deposit option. Employers decide on hiring and sponsorship.
