Mechanical engineering salaries across sectors in 2026 — aerospace to building services — with after-tax figures.
Mechanical engineering pay tracks similarly to civil but varies more by sector: aerospace, defence, oil & gas and automation pay at the top; building services and general manufacturing at the lower-middle. Graduates start around £27,000–£30,000, mid-level engineers earn £38,000–£48,000, and chartered seniors (CEng via IMechE) £50,000–£70,000.
| Level | Typical salary | Take-home / year | Take-home / month |
|---|---|---|---|
| Graduate engineer | £28,000 | £23,680 | £1,973 |
| Engineer (3–5 yrs) | £42,000 | £33,760 | £2,813 |
| Senior engineer (chartered) | £55,000 | £42,457 | £3,538 |
| Lead / principal engineer | £68,000 | £49,997 | £4,166 |
| Engineering manager | £82,000 | £58,117 | £4,843 |

Defence and oil & gas commonly pay 15–25% above general manufacturing for the same grade, and contract roles in those sectors reach £400–£600/day. Many senior mechanical engineers move into contracting — IR35 status and umbrella deductions decide whether it pays; compare with our Umbrella Pay Calculator.
Graduates £27,000–£30,000; experienced engineers £38,000–£48,000; chartered seniors £50,000–£70,000, with defence and energy sectors paying at the top of each range.
Oil & gas, defence and aerospace typically lead, followed by automation and pharmaceuticals; building services and general manufacturing pay least.
Yes, especially in energy and defence — day rates of £400–£600 for senior engineers, but IR35 status heavily affects the real take-home.
