Methodology: medians reconcile live advertised UK salaries for this role and region; 25th–75th percentiles are shown only where at least 5 live salaried listings back them. They are measured or omitted, never interpolated. Rows marked indicative are anchored to our curated 2026 baseline ranges until enough live data accrues. Listings advertising an implausible annual figure (a mislabelled hourly or daily rate) are excluded rather than converted, because converting one means guessing the hours behind it.
Market view. Scotland's energy sector (offshore, renewables) pushes mechanical pay above most English regions outside London. Chartership (CEng via IMechE) matters for engineer-grade roles; for fitters, recognised apprenticeships plus experience on rotating equipment, hydraulics or press tools carry the premium.
