Mechanical engineering spans one of the broadest sector ranges of any engineering discipline, covering everything from defence and aerospace to food manufacturing and consumer goods, which creates wide salary variation depending on the industry chosen. IMechE's 2024 survey found median salary of £48,000 for all mechanical engineers and £62,000 for Chartered Engineers (CEng), with aerospace and oil and gas commanding the strongest premiums. The energy transition in offshore wind, hydrogen, and nuclear is creating strong demand for mechanical engineers with relevant project experience.
Based on typical mechanical engineer salaries, here is what you can expect to take home after income tax and National Insurance:
- Graduate Mechanical Engineer: £23,681 take-home (£28,000 gross, outside London) / £28,001 take-home (£34,000 gross, London)
- Mechanical Engineer (towards CEng): £35,921 take-home (£45,000 gross, outside London) / £43,038 take-home (£56,000 gross, London)
- Senior / Chartered Mechanical Engineer (CEng): £48,258 take-home (£65,000 gross, outside London) / £56,958 take-home (£80,000 gross, London)
Key facts about mechanical engineer pay:
