How this figure was built. Based on 105 live advertised salaries for this role and region, 8 of which were the source's own estimate rather than an advertised figure.

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. Commercial tickets (COCN1/CODNCO1 families) pay above domestic-only (CCN1) work, and combined gas + renewables capability (heat pumps via MCS-accredited employers) is an emerging premium. On-call rotas and van-based service patches make real earnings package-dependent; self-employed engineers price differently again.
