Site Engineer vs Tunnel Engineer: advertised pay

Not enough adverts state pay on both sides to compare Site Engineer and Tunnel Engineer. Each side is below with its own sample, and this page stays out of search results until both reach five adverts stating pay.

Site Engineer, median advertised salary£77,625advertised · 295 adverts stating pay · 04 Oct 2026 Tunnel Engineer, median advertised salaryNot enough adverts yet to publish a figure.

The two samples are different sets of adverts from different employers, so a gap between them is a gap in what is being advertised.

Advertised, not paid: these are the salaries employers stated in live job adverts. They are not a survey of what people are paid, and this site neither sets nor guarantees any rate.
