Lift Engineer (Mid-Level) vs Plumber (Journey-Level)
How do Lift Engineer (Mid-Level) and Plumber (Journey-Level) compare on AI displacement risk? Lift Engineer (Mid-Level) scores 66.4/100 (GREEN (Stable)) while Plumber (Journey-Level) scores 81.4/100 (GREEN (Stable)). Here's the full breakdown.
Lift Engineer (Mid-Level): Installs, maintains, and repairs passenger and goods lifts/elevators -- LEIA-certified, NVQ Level 3. Electrical and mechanical work inside lift shafts, machine rooms, and pit areas across residential, commercial, and public buildings. Strong physical barriers, regulatory licensing, and persistent skills shortages protect the role despite AI-driven predictive maintenance and remote diagnostics reducing routine callouts. ~25,000 UK workforce.
Plumber (Journey-Level): Near-maximum Green — every signal converges. Physical work in unstructured environments, licensing barriers, acute labour shortage, and AI infrastructure indirectly boosting demand. AI cannot fix a burst pipe behind a wall.

What Do These Scores Mean?
Each role is assessed using the AI Job Resistance Index (AIJRI), a composite score from 0 to 100 measuring how resistant a role is to AI displacement. The score is built from five dimensions: Task Resistance (how many core tasks can AI automate), Evidence Calibration (real-world adoption data), Barriers (regulatory, physical, and trust barriers protecting the role), Protective Principles (human-centric factors like empathy and judgement), and AI Growth Correlation (whether AI growth helps or hurts the role).
Roles scoring above 60 land in the Green Zone (AI-resistant), 40–60 in the Yellow Zone (needs adaptation), and below 40 in the Red Zone (high displacement risk). For full individual assessments, see the Lift Engineer (Mid-Level) and Plumber (Journey-Level) role pages.
