Understanding Engineering Salary in the UK

If you are an engineer or considering a career in engineering, knowing how to convert an hourly rate into an annual salary is essential. This guide uses the latest official UK data to help you benchmark your earnings and understand the factors that influence pay.

What the Latest ONS Data Tells Us

The Office for National Statistics (ONS) Annual Survey of Hours and Earnings (ASHE) for 2025 shows that the median gross annual earnings for full-time employees across all occupations was £39,039. The median hourly rate (excluding overtime) was £19.67, and median weekly earnings were £766.60. While these figures are not specific to engineering, they provide a useful baseline. Engineering roles often command higher pay, especially in sectors like aerospace, oil & gas, and software engineering.

For a more tailored view, the ONS also publishes the Average Weekly Earnings (AWE) for Engineering & Allied Industries, which tracks pay trends over time. However, the latest release (August 2026) does not give a single current level, so we rely on the broader ASHE data for now.

Hourly to Annual Conversion: The 37.5-Hour Week Rule

Most full-time engineering roles in the UK are based on a 37.5-hour working week (though some use 35, 37, or 40 hours). To convert an hourly rate to an annual salary, use the formula:

Annual salary ≈ hourly rate × hours per week × 52 weeks

For example, if you earn £25 per hour and work 37.5 hours per week:

£25 × 37.5 × 52 = £48,750 gross per year.

This calculation assumes you are paid for all 52 weeks, including holiday pay. If your contract uses a different week length (e.g., 40 hours), adjust accordingly. Always check your contract for the exact hours and any unpaid breaks.

Part-Time vs Full-Time Engineering Salaries

Part-time engineering roles (typically ≤30 hours per week) are common in consultancy, maintenance, and project management. The hourly rate is often the same as full-time, but the annual salary is proportionally lower. For instance, a part-time engineer working 20 hours per week at £20 per hour would earn £20,800 annually (20 × 20 × 52).

ONS data shows that part-time median weekly earnings were £280.00 in April 2025, up 6.4% from the previous year. This growth partly reflects the National Living Wage increase, which affects lower-paid roles. Engineering part-time roles may be higher paid, but the same conversion principle applies.

National Living Wage and Engineering Pay

The National Living Wage (NLW) for workers aged 21 and over was £12.21 per hour in April 2025. Most engineering roles pay well above this, but it serves as a floor. For 2026/27, the government has not yet announced the new NLW rate, but it typically rises each April. If you are on a low engineering wage, check that your employer meets the legal minimum.

NHS Pay Scales: A Comparison

While not engineering, NHS pay scales offer a useful benchmark for public sector roles. For 2026/27, NHS Band 1 (entry level) pays £25,272 annually (£12.92/hr), Band 5 (e.g., newly qualified nurses) ranges from £16.40 to £19.97 per hour, and Band 6 (specialist roles) starts at £20.44 per hour. Engineering roles in the public sector (e.g., highways, defence) may follow similar banding structures.

London Weighting and Overtime

Many engineering jobs in London and the South East include a London weighting allowance, which can add £3,000–£5,000 to your base salary. Overtime is common in engineering, especially in manufacturing, construction, and maintenance. Overtime rates are often 1.5× or 2× the base hourly rate. When converting your total annual earnings, remember to include these extras if they are regular.

Summary

• The median full-time UK salary is £39,039 (April 2025), but engineering roles often exceed this.
• Convert hourly to annual using hours per week × 52.
• Part-time roles reduce annual pay proportionally but hourly rates remain similar.
• Always check for London weighting, overtime, and your exact contracted hours.
• Use official ONS and GOV.UK sources for the most accurate benchmarks.
