What the Average Salary in UK Really Means: ONS Data vs Advertised Pay

What the Average Salary in UK Really Means

When you search for the average salary in UK, you'll quickly encounter two main numbers: the median and the mean. The Office for National Statistics (ONS) publishes these each year in its Annual Survey of Hours and Earnings (ASHE). For April 2025, the median full-time gross annual salary was £39,039, while the mean was around £45,800. But what do these figures actually tell you, and how do they compare to the salaries you see advertised on job boards?

Median vs Mean: Which is More Useful?

The ONS prefers the median because it represents the middle point of all salaries. If you line up every full-time employee from lowest to highest earner, the person in the exact middle earns the median. This is less distorted by the very high salaries of top executives or City bankers. The mean, on the other hand, adds up all earnings and divides by the number of employees, so a handful of very high earners can pull the average up. For most job seekers, the median gives a more realistic picture of typical pay.

What the ONS Data Actually Covers

ASHE is based on a 1% sample of employees from HMRC PAYE records. It captures pay for employees who have been in the same job for at least a year, so it excludes people who recently changed jobs or started new roles. This means the figures may lag behind current market rates. The data also includes bonuses, overtime, and other payments, but only for the reference pay period in April. Annual earnings are calculated from those weekly or monthly figures.

Key findings from the 2025 release:

• Median weekly earnings for full-time employees: £766.60 (up 5.3% on 2024)
• Median hourly earnings (excluding overtime): £19.67 (up 5.4%)
• Real terms increase after inflation (CPIH): 1.1%

How Advertised Pay Differs

Job adverts often show higher salaries than the median because employers are competing for new talent. They may also exclude bonuses or benefits that ASHE includes. For example, a job listing might say "£45,000" but the median for that occupation could be £42,000. Additionally, many adverts are for roles in London or the South East, where pay is higher, while the UK median includes all regions. Always check the salary data for your specific occupation and region to get a clearer picture.

The National Living Wage and Minimum Wage

For lower-paid workers, the National Living Wage (NLW) sets a floor. In April 2025, the NLW for employees aged 21 and over was £12.21 per hour. For someone working 37.5 hours a week, that works out to about £23,810 per year. The rate increased to £12.71 in 2026/27, giving an annual salary of around £24,785. These figures are below the median, but they ensure a minimum standard. The ONS also publishes a Low and High Pay bulletin that examines how many employees earn near the minimum wage.

Regional Variations

Average salary in UK varies significantly by region. In April 2025, Northern Ireland saw the highest growth in median full-time weekly earnings (7.4%), partly due to public sector pay awards. The South East had the smallest growth (2.9%). London remains the highest-paying region, but its median is not published in the main bulletin; you can explore local authority data on the ONS interactive chart. If you're considering a move, check the salary index for your target area.

Scotland's Different Tax Bands

If you live in Scotland, your Income Tax bands are different from the rest of the UK. The Scottish Government sets its own rates, which can affect take-home pay, especially for higher earners. For example, the starter rate is 19%, the basic rate is 20%, and higher rates apply above certain thresholds. This means that even if your gross salary matches the UK average, your net pay may be lower or higher depending on where you live. Always factor in tax when comparing job offers.

Take-Home Pay: What You Actually Receive

The average salary in UK figures are gross (before tax and National Insurance). Your take-home pay depends on your tax code, pension contributions, student loan repayments, and any salary sacrifice schemes. A useful rule of thumb: for a median salary of £39,039, a single person without a student loan might take home around £2,600 per month after tax and NI, but this varies. Use the GOV.UK tax calculator for a precise estimate.

Why the Mean is Higher

The mean full-time annual salary of £45,800 is about £6,700 higher than the median. This gap shows that a relatively small number of very high earners pull the average up. For most employees, the median is a better benchmark. However, if you are in a high-paying sector like finance or law, the mean might be more relevant because your peers are likely above the median.

How to Use This Information

When negotiating a salary or evaluating a job offer, compare it to the median for your occupation and region. The ONS publishes breakdowns by two-digit occupation codes, which you can find in the ASHE dataset. Also consider the total compensation package, including pension, bonus, and benefits.

Summary

The average salary in UK is not a single number. The ONS median of £39,039 is the most reliable benchmark for typical full-time pay, but advertised salaries, regional differences, and your personal circumstances all matter. Always look beyond the headline figure to understand what you can expect to earn and take home.

Frequently Asked Questions

What is the difference between median and mean average salary in UK?

The median is the middle value when all salaries are ranked, so it is not skewed by a small number of very high earners. The mean is the total sum of all salaries divided by the number of employees, which can be pulled upwards by top earners. The ONS uses median as its preferred measure for average salary in UK because it better represents typical pay.

How does advertised salary compare to the official average salary in UK?

Advertised salaries on job sites often reflect what employers are willing to pay for new hires, which can be higher than the median for existing employees. Official ONS ASHE data captures actual pay for all employees in a job for at least a year, so it may lag behind advertised rates. Additionally, many adverts exclude bonuses or overtime, while ASHE includes them where applicable.

Does the average salary in UK include part-time workers?

No, the headline average salary in UK figures from ONS ASHE are for full-time employees only. Part-time workers have lower median earnings. For a full picture, the ONS publishes separate data for part-time employees, and the Low and High Pay bulletin examines hourly pay across all workers.
