Understanding the Full Stack Developer Salary in the UK

If you are a full stack developer or considering a career in this field, knowing the typical full stack developer salary is essential for negotiating offers or planning your next move. Salaries vary significantly by region, seniority, and sector. This article draws on the latest UK data from the Office for National Statistics (ONS), NHS pay scales, and a reputable pay survey to give you a clear picture.

Hourly Rates and Annual Salary Conversion

Most full-time roles are based on a 37.5-hour week, though some employers use 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, at £36 per hour (the average for full stack developers according to a 2025 survey), working 37.5 hours a week gives:

£36 × 37.5 × 52 = £70,200 per year.

If you work 40 hours, it becomes £74,880. Always check your contract for exact hours and overtime rules. Our Hourly to Salary tool can do the maths for you.

National Benchmarks from ONS and Government

The ONS Annual Survey of Hours and Earnings (ASHE) for 2025 reports that median weekly earnings for full-time employees were £766.60, with median hourly earnings at £19.67 and median annual earnings at £39,039. This covers all occupations, not just tech. The National Living Wage for employees aged 21 and over was £12.21 per hour in April 2025. Full stack developers earn significantly more than these baselines, reflecting the high demand for their skills.

For public sector comparison, NHS Employers published 2026/27 pay scales showing Band 6 hourly rates at £20.44 and Band 1 at £12.92. While NHS roles are not directly comparable, they provide a floor for professional pay in the UK.

Regional Differences in Full Stack Developer Pay

Location plays a major role in determining your full stack developer salary. According to Salary.com Global Salary IQ data (2025), the top-paying cities are:

• London: £79,771 per year (average)
• Brighton and Hove: £74,411
• Manchester: £70,800

London weighting can add 10–20% to base pay, but the higher cost of living offsets some of the gain. ONS data also shows regional earnings growth: Northern Ireland saw the highest increase (7.4%) in median full-time weekly earnings between 2024 and 2025, while the South East had the smallest (2.9%). This suggests that salaries outside London are rising, though absolute levels remain lower.

Seniority and Experience Levels

Pay rises steeply with experience. The same survey breaks down average full stack developer salaries by seniority:

• Entry Level: £70,386
• Intermediate: £71,176
• Senior: £72,282
• Specialist: £75,737
• Expert: £78,550

These figures show that even entry-level roles pay well above the UK median. As you gain expertise, your earning potential increases, especially if you move into leadership or specialise in high-demand technologies.

Overtime, Bonuses, and London Weighting

Base salary is only part of the picture. Many full stack developers receive bonuses, stock options, or overtime pay. London weighting is common in the capital, adding a fixed allowance or percentage to attract talent. Always factor these into your total compensation when comparing offers. Our salary articles cover how to evaluate total packages.

How to Use This Data

When negotiating a salary, use the ONS median as a baseline and the pay survey averages as a target. Remember that actual pay depends on company size, industry (finance, tech, public sector), and your specific skill set.
