Understanding Aerospace Engineer Salary in the UK

When researching an aerospace engineer salary in the UK, it’s important to look beyond headline figures and understand how hourly rates, overtime, and location allowances affect your take-home pay. The Office for National Statistics (ONS) Annual Survey of Hours and Earnings (ASHE) is the most authoritative source for earnings data by occupation. However, as of the latest provisional 2025 data, a specific four-digit SOC code for “aerospace engineer” is not published in the standard tables; instead, aerospace engineers are grouped under broader engineering professional categories such as design and development engineers (SOC 2126) or engineering professionals n.e.c. (SOC 2128).

Hourly Rate vs. Annual Salary: The Conversion Rule

A common myth is that your annual salary is simply your hourly rate multiplied by 40 hours per week and 52 weeks. In reality, many UK engineering roles are contracted at 37.5 hours per week (excluding unpaid breaks). The standard conversion used on this site is:

Annual salary ≈ hourly rate × 37.5 hours/week × 52 weeks

For example, if your hourly rate is £25, the approximate annual salary would be £25 × 37.5 × 52 = £48,750. This assumes no unpaid overtime, no bonus, and no salary sacrifice. Always check your contract for the exact weekly hours.

Overtime Myths: “Time and a Half” Isn’t Always Guaranteed

Many aerospace engineers assume overtime is paid at a premium rate (e.g., 1.5× hourly). While this is common, it is not a legal requirement. The National Minimum Wage regulations only require that total pay over the pay reference period averages at least the minimum wage – overtime can be unpaid if your contract states that your salary covers all hours worked. For aerospace engineers on a fixed annual salary, overtime may be unpaid or compensated with time off in lieu (TOIL). Always clarify overtime policy before accepting a role.

London Weighting and Regional Differences

Aerospace engineer salaries vary significantly by region. ONS ASHE Table 3 provides earnings by region and two-digit SOC. In London and the South East, employers often add a London weighting – typically £3,000 to £5,000 per year – to attract talent. However, this is not universal. When comparing job offers, consider the cost of living: a £50,000 salary in London may be equivalent to £42,000 in the Midlands after housing costs.

Using ONS ASHE Data for Benchmarking

The ONS publishes several ASHE tables relevant to aerospace engineers:

• Table 2 (two-digit SOC): Median earnings for engineering professionals (SOC 21). The 2025 provisional data is available as a zip file from the ONS website.
• Table 14 (four-digit SOC): More granular data for occupations like design and development engineers (2126).
• Table 29 (industry and occupation): Earnings broken down by industry section (e.g., manufacturing) and occupation.

These datasets include coefficients of variation to indicate reliability. For the most accurate benchmark, download the latest provisional or revised dataset from the ONS.

Common Myths About Hourly Pay and Overtime

Myth 1: “Your hourly rate is your annual salary divided by 2,080.” This assumes a 40-hour week, but many UK roles use 37.5 hours. Using 2,080 hours overestimates the hourly rate. Use 1,950 hours (37.5 × 52) for a more accurate conversion.

Myth 2: “Overtime is always paid at 1.5×.” Not true. Some contracts include overtime in the annual salary (e.g., “you may be required to work reasonable overtime”). Check your employment contract or staff handbook.

Myth 3: “London weighting is a fixed percentage.” In reality, it’s often a flat amount or a banded allowance, not a percentage of salary. Always ask for the specific figure.

How to Use This Site for Your Salary Research

Use our Hourly to Salary tool to convert your hourly rate to an annual figure based on your contracted hours.

Final Thoughts

An aerospace engineer salary in the UK depends on experience, location, and employer. While ONS ASHE provides robust national averages, always verify with your specific job offer. Remember that hourly-to-annual conversions are estimates – your actual pay may include bonuses, shift allowances, or pension contributions. Use the official GOV.UK guidance on National Living Wage and tax bands to ensure you’re being paid fairly.
