Heat Pump Installer (Mid-Level) vs Overhead Line Engineer — Railway (Mid-Level)
How do Heat Pump Installer (Mid-Level) and Overhead Line Engineer — Railway (Mid-Level) compare on AI displacement risk? Heat Pump Installer (Mid-Level) scores 83.5/100 (GREEN (Transforming)) while Overhead Line Engineer — Railway (Mid-Level) scores 72.8/100 (GREEN (Stable)). Here's the full breakdown.
Heat Pump Installer (Mid-Level): Near-maximum Green — UK government targets, record installations, severe MCS-certified installer shortage, and irreducible physical work converge. Every installation involves drilling through walls, running pipework, handling refrigerants, and commissioning in unpredictable residential environments. AI assists with heat loss calculations and admin, but cannot install a heat pump. The gas boiler phase-out creates a decade of guaranteed demand growth with no AI displacement pathway.
Overhead Line Engineer — Railway (Mid-Level): Physical work at height on 25kV live catenary in unstructured railway environments, combined with acute UK skills shortage and strong union/regulatory barriers, makes this role highly AI-resistant. Electrification expansion (CP7, HS2) sustains demand through 2030+. Safe for 10+ years.

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 Heat Pump Installer (Mid-Level) and Overhead Line Engineer — Railway (Mid-Level) role pages.
