From Skills Shortage to Capability Gap: Preparing Technicians for EV and ADAS Challenges

08 Jun From Skills Shortage to Capability Gap: Preparing Technicians for EV and ADAS Challenges

For years, workshop leaders have talked about a “technician shortage” as if the only problem was headcount. But the market signals are changing. In late 2025, UK motor trade vacancy rates sat at around 2.9% (close to the 3% mark), which suggests the conversation is no longer just about empty ramps—or even vacancy density alone.

The bigger issue is a capability gap: you may have technicians in post, but not enough people who can safely isolate high-voltage systems, handle and diagnose battery faults, interpret live data streams, or complete ADAS calibration to the standard customers (and insurers) now expect.

This is where workshops win or lose margin over the next decade.

Why “capability” is now the constraint (not just hiring)

A few forces are converging at once:

• EV adoption is pushing new safety-critical tasks into everyday servicing (high-voltage isolation, battery condition triage, thermal events, safe storage and transport).
• ADAS is turning routine repairs into precision work where geometry, targets, scan tools, software versions and documentation matter as much as spanners.
• The workforce is ageing, making replacement and knowledge transfer harder: IMI workforce reporting shows over 47% of employees are aged 45+ in the sector. (tide.theimi.org.uk)

At the same time, training pipelines are improving but still lag the pace of change. Britain added 1,700 apprenticeships in 2025 (a 33% increase), yet industry warnings suggest 61% of roles will require new skills by 2035. (automotivemanufacturingsolutions.com)

So yes, you still need good people. But increasingly, you need different capability, and you need it faster—because employer demand is shifting from “hands on ramps” to evidence-led diagnostics, and the wider UK workforce is feeling similar pressure across manufacturing, construction, and even service industries.

The practical reality in workshops: where the gap shows up

Capability gaps typically appear in three places.

1) High-voltage systems and safe working practices

Many workshops can “service” an EV, but fewer can confidently:

• verify isolation and prove dead correctly
• identify HV interlock loop faults and insulation resistance concerns
• triage faults without swapping expensive parts “to see if it fixes it”
• apply consistent procedures when a job is interrupted mid-process (handover risk)

The consequence is often job delay, higher comebacks, or a decision to sublet work that could have been kept in-house—especially in small independents with 2 to 4 employees, where one absence creates an immediate capacity mismatch. (The same pattern often shows up in growing sites with 5 to 24 employees, where skills exist, but are clustered in one or two people.)

2) Battery handling, diagnosis and decision-making

Battery work isn’t one skill; it is a mix of:

• safe handling and storage
• diagnostic reasoning (cell/module vs BMS vs thermal vs wiring)
• documentation and reporting (especially for warranty/insurer decisions)

If your team can’t produce clear evidence (test results, logs, before/after), you get stuck between customer expectations, parts cost and uncertainty—and the incidence of “parts-darts” decisions tends to rise.

3) ADAS calibration and post-repair validation

ADAS is one of the clearest examples of the capability gap.

IMI has previously highlighted the scale of the challenge, estimating the industry will need 106,000 ADAS-qualified technicians by 2030 to meet demand. (tide.theimi.org.uk)

Meanwhile, independent market research has suggested two-thirds of garages have no technicians qualified to carry out ADAS calibration and repair work, which is a serious risk for road safety, reputation and insurer relationships—and directly linked to customer health outcomes after a repair.

Skills shortage vs capability gap: a simple way to explain it to your team

Challenge	What it looks like day-to-day	Typical symptom	What fixes it
Skills shortage	Not enough technicians overall	Long lead times, overtime, ramp pressure	Recruitment, retention, pay, scheduling
Capability gap	Enough staff, but not enough right skills	Subletting EV/ADAS, slow diagnosis, comebacks, inconsistency	Targeted training, process, tooling, mentorship
Capacity mismatch	Skills exist, but not available at the right times	Bottlenecks around one “go-to” tech	Cross-skilling and job planning

The most effective approach is not to send “everyone on everything”. It’s to build a capability model that matches your car parc, your work mix and your ambitions—whether you’re in London, the South East, the South West, the West Midlands, or Yorkshire and the Humber (each English region can feel the gap differently depending on vehicle mix and local competition).

Step 1: map your work mix and risk points

Start with the last 90 days:

• What percentage of jobs involved EVs or hybrids?
• How many repairs required post-repair scanning or calibration?
• Where did you sublet, delay, or escalate to a master tech?

Then identify your top 5 “risk points” (e.g., “front camera calibration after windscreen”, “alignment + calibration packaging”, “hybrid isolation procedure”).

If you want a simple benchmark, treat your sublet volume and comeback themes like a workshop “incident log”: you’re tracking the incidence of risk events, not just the number of jobs.

Step 2: define roles in a capability ladder (not job titles)

Instead of thinking “technician vs master technician”, define capability tiers, such as:

• EV awareness: can service safely, recognise when to escalate
• EV competent: can isolate, test, diagnose common faults
• EV specialist: can handle higher-risk diagnosis, battery-related decision pathways
• ADAS competent: can complete pre/post scans and follow OEM calibration procedures
• ADAS specialist: can diagnose calibration failures, environmental/setup issues, and document outcomes

This makes training spend measurable and avoids “training for training’s sake”—and it gives applicants a clearer development path when they compare employers.

Step 3: build a repeatable diagnostic process (and make it teachable)

Modern diagnostics is not about a single tool. It’s a workflow:

1. Confirm concern and capture evidence (customer statement + symptom reproduction)
2. Pre-repair scan and health check (record DTCs, freeze-frame, software versions)
3. Guided test plan (choose tests that eliminate branches of the fault tree)
4. Repair with quality gates (torque, alignment, connector handling, insulation checks)
5. Post-repair verification (road test + scan + calibration where required)
6. Documentation (what you found, what you tested, what changed)

If you can standardise this workflow, you can scale skill faster—especially with apprentices and improvers. Some workshops formalise this with consistent sign-off templates (including internal “SSVS” job-card checklists—Service & Safety Verification Sheets) so handovers don’t rely on memory.

Step 4: invest in “train-the-trainer” inside the business

External courses matter, but workshops accelerate fastest when they have internal coaches.

Pick one or two technicians who are:

• calm under pressure
• consistent with process
• good at explaining why, not just what

Give them protected time each week to coach, review job cards, and run short toolbox sessions.

(As a comparison: other sectors with compliance-heavy work—like utilities and social work—have long relied on supervised practice and internal coaching to reduce risk. Automotive is increasingly moving the same way.)

Step 5: package ADAS properly (so it is profitable, not painful)

ADAS work becomes a margin-drain when it’s treated as an add-on.

Consider creating:

• a defined scan-and-calibration bundle
• a controlled bay space (lighting, floor markings, target distances)
• a checklist for prerequisites (tyre pressures, ride height, alignment status, windscreen spec, software updates)

Even if you sublet calibrations today, packaging the process improves customer trust and reduces awkward conversations when a calibration is required.

Where recruitment fits: hiring for learnability, not just today’s skills

As technology shifts, a “perfect CV” is less common. Workshops that hire well are increasingly selecting for:

• structured thinking (diagnostic discipline)
• willingness to follow procedure (especially for HV and ADAS)
• learning agility and professional pride

This is where a specialist recruiter can save time and reduce mis-hires—especially when you need technicians who can grow into EV/ADAS capability, not just fill a ramp this month.

A realistic 90-day action plan for workshop leaders

If you want momentum without disruption, this is a practical sequence:

1. Weeks 1–2: audit EV/ADAS job volume + sublet spend + comeback themes
2. Weeks 3–4: define your capability ladder and nominate internal coaches
3. Month 2: run two short weekly toolbox sessions (process + safety + evidence capture)
4. Month 3: formalise ADAS workflow (pre-scan, prerequisites, documentation, post-scan) and track job times

The goal is simple: fewer bottlenecks, faster diagnosis, safer work, and a team that can keep pace with the car parc—not just the vacancy rate.

Closing thought: capability is your competitive advantage

Vacancy rates will rise and fall with the economy. Capability compounds.

Workshops that treat EV and ADAS as a structured capability build—supported by process, coaching, and smart recruitment—will protect profitability, reduce risk, and become the place good technicians want to stay—and feel at home in the next generation of diagnostics.

(And while automotive sits mainly in the service side of the “three sectors employers” view—alongside the primary sector and production-heavy sectors like manufacturing—the same three pillars keep showing up: people, process, and tooling. Get those right, and you reduce labour shortages pain even when the market swings between local talent surplus and scarcity.)

If you want to sanity-check your approach, it can also help to align internal training evidence and compliance with common external expectations (for example, referencing guidance and frameworks published on gov.uk, where relevant), and keep a clear record of replacement needs planning so knowledge doesn’t walk out the door during the next wave of retirements.
