How much does a Mechanical Engineer make in London, UK?
A Mechanical Engineer in London earns a median of $85,020/year (about $41/hour). Most earn between $66,477 (25th percentile) and $110,833 (75th percentile); top earners (90th percentile) make $128,140 or more — 8% below the US average. Figures are from BLS employer payroll data, not self-reports.
Understanding these Mechanical Engineer salary numbers
We report percentiles, not a single average, because pay isn't evenly spread — a handful of very high earners would drag an average upward and mislead you. Here's exactly what each figure means.
Median (P50) — $85,020
Half of Mechanical Engineers in London earn more than this and half earn less. It's the most honest "typical" salary — better than an average, which gets skewed by a few top earners.
25th percentile (P25) — $66,477
The lower end of the typical range: 75% of Mechanical Engineers earn more than this. It's common for early-career roles or lower-cost employers. Earning below it is grounds to negotiate.
75th percentile (P75) — $110,833
Your negotiation target: only 25% of Mechanical Engineers earn above it. Reaching P75 usually means seniority, in-demand specialisations, or simply negotiating from data. See how to negotiate.
90th percentile (P90) — $128,140
Top earners: only 10% of Mechanical Engineers make this or more — typically senior, highly specialised, or at the best-paying employers.
Gross vs after-tax pay
These figures are gross (before tax). What actually reaches your account depends on your country, state, and deductions. Estimate your net with the take-home calculator.
National vs London pay
City figures apply the local market premium to BLS data, so London differs from the US average by -8%. A higher number isn't always better once cost of living is counted.
Hourly rate — $41/hr
The hourly figure is the annual median divided by 2,080 (40 hours × 52 weeks). If you regularly work more than 40 hours, your real hourly rate is lower than this. Convert any salary with the salary calculator.
Why this differs from Glassdoor or Payscale
Those sites publish what people say they earn (self-reports), which skew high because higher earners report more often. Our figures come from mandatory employer payroll records (BLS OEWS), so they reflect the whole market — not just a vocal subset.
How current and reliable is this number?
This page carries a confidence score of 81/100, based on the data source and coverage. US figures track the latest BLS release and refresh automatically; international figures use OECD/ILO data. See the changelog for live data freshness.
What counts as a "good" Mechanical Engineer salary in London?
Around the median ($85,020) is solid and $110,833+ is strong — but "good" really depends on local costs. Check what the number is actually worth with the good-salary breakdown for London.
