Salary data for developers is never one clean number. Ask different sources what a full stack software developer salary looks like and you will get answers that sit within a few thousand pounds of each other but rarely match exactly. That small spread is actually useful, because it tells you the market has a fairly consistent centre even when the methods behind each figure differ.
The headline full stack developer salary figures for 2026
Across the UK, the average and median figures published by the major salary sites cluster in the high fifties and low sixties. Indeed reports an average of £57,566 per year for a full stack developer in the United Kingdom, with salaries typically ranging from a low of £32,331 to a high of £102,497. A more recently updated Indeed snapshot puts the average base salary at £57,744 per year, based on 3.1k salaries reported.
IT Jobs Watch takes a different approach, looking at advertised vacancies rather than reported pay, and arrives at a median of £60,000 per year for the six months leading to 24 September 2026. Glassdoor lists an average of £59,597 per year, or £29 per hour, for a Full Stack Engineer, with top earners reaching £98,017 at the 90th percentile.
| Source | Reported figure | Notes |
|---|---|---|
| Indeed | £57,566 average per year | Typical range of £32,331 to £102,497 |
| Indeed (later update) | £57,744 average base salary | Based on 3.1k salaries reported |
| IT Jobs Watch | £60,000 median | Advertised vacancies, six months to 24 September 2026 |
| Glassdoor | £59,597 per year, £29 per hour | Full Stack Engineer title, 90th percentile at £98,017 |
| CWJobs | £62,500 average | Older 2021 estimate, use as historical context only |
The CWJobs estimate also suggested that experienced full stack developers could earn between £75,000 and £95,000. Because that figure dates from 2021, it is more useful as a marker of how the top end has been described over time than as a current benchmark.
Why the published averages do not match exactly
Each source draws from a different pool. Indeed and Glassdoor lean heavily on salaries reported by employees, which means the numbers reflect people who chose to share their pay, and self-selection can nudge an average in either direction. IT Jobs Watch measures advertised vacancies, which captures what employers are willing to offer rather than what staff actually receive once they are in post.
Job titles add another layer of noise, since full stack developer and full stack engineer are often used interchangeably for the same work. Sample sizes matter too: an average built on a few thousand reports carries more weight than one built on a much smaller set.
What matters more than picking a single winning figure is the shape of the market. The pattern across all of these sources is a broad middle between roughly £55,000 and £60,000, a lower bound in the low thirties for people in their first role, and a long tail stretching past £100,000 for the most senior or most specialist positions.
How experience changes the numbers
Experience is the single biggest lever on pay. One 2026 salary guide breaks the market into bands that show a clear step up after the first year or two in a commercial role.
| Experience level | Reported range |
|---|---|
| Full stack developer, 0 to 1 year | £35,000 to £58,000 |
| Full stack engineer, 1 to 3 years | £45,000 to £66,000 |
The overlap between those two bands matters. A strong junior at a well-funded company can out-earn a mid-level developer at a smaller firm, which is why ranges tell you more than job titles alone. It also means the first role is less about squeezing out an extra thousand pounds and more about landing somewhere that will move you into the next band within a couple of years.
Location still shifts the figure
National averages smooth out real regional differences. One available city breakdown puts Fullstack Engineers working in Birmingham at around £55,000 per year, with most salaries falling between £42,500 and £82,500. That sits below the national average, and it reflects a pattern seen across most technical roles: pay tends to track the cost of living and the concentration of employers in a given area.
City level data is patchier than national data, so if you are weighing up a move it is worth checking current job adverts in that specific market rather than relying on a single published average. Salaries elsewhere in Europe vary widely from country to country, and US-focused platforms report figures in dollars that reflect an entirely different market, currency and benefits structure. A UK average is not transferable across borders.
Demand for full stack developers
Salary only holds up when there is demand behind it, and the vacancy data gives a reasonable picture. IT Jobs Watch recorded 1,018 permanent jobs requiring a Full-Stack Developer in the six months to 24 September 2026, which represented 0.87 per cent of all permanent jobs advertised in the UK.
That compares with 439 permanent vacancies in the same period a year earlier, and 1,059 in the equivalent 2024 period. The swing between 2025 and 2026 suggests hiring bounced back after a quieter stretch, though the share of overall vacancies has stayed fairly steady at just under 1 per cent throughout.
Why some full stack developers earn far more
The gap between the average and the top of the range is wide, and it usually comes down to how much a developer can handle independently. A full stack role covers both the front end and the back end of a website, web application, or program, which means employers are paying for someone who can move between the two without needing another specialist to fill the gap.
Common routes to the upper end include taking on senior or lead responsibility, working in sectors that pay a premium for technical staff, and building genuine depth in one stack rather than staying a shallow generalist. The reported 90th percentile figure of £98,017 is not a typical outcome, but it is a realistic ceiling for people who keep progressing and keep their skills current.
What this means if you are starting out
Entry level pay in the mid thirties is normal for a first developer job, and the jump after a couple of years is usually the biggest single increase you will see in your career. That makes the first role less about maximising salary and more about getting the commercial experience that moves you up a band.
Structured training can shorten the distance between having no professional experience and being hireable. Code Success runs a self-paced online Full Stack Developer Course covering HTML, CSS, JavaScript, PHP, MySQL, ReactJS, Symfony, XML and JSON, and APIs, priced at £4,995 over nine months, with job placement support through UK recruitment agencies. There is also a free five-day taster course if you would rather test the water before committing to a longer programme.
Reading salary data sensibly
Treat every figure in this article as a guide rather than a promise. Averages blend together people with wildly different skills, locations and levels of responsibility, and the number attached to any individual job offer depends on the employer, the interview, and how well you can demonstrate what you bring.
The most practical approach is to check two or three sources, look at live adverts for the roles you actually want, and compare the range on offer with the national figures above. If a role sits well below the low end of the range, that tells you something. If it sits above the average, that tells you something too, usually about seniority or specialism.
Frequently Asked Questions
What is the average full stack software developer salary in the UK?
Published figures cluster between £57,000 and £60,000 a year. Indeed reports an average of £57,566, Glassdoor lists £59,597 for full stack engineers, and IT Jobs Watch gives a median of £60,000 based on advertised vacancies. Treat these as a guide to the middle of the market rather than a guarantee of what any single role will pay.
How much can a junior full stack developer earn?
Entry level pay sits below the national average. One 2026 salary guide puts full stack developers with zero to one year of experience at £35,000 to £58,000, while Indeed's overall range starts at £32,331. The first two years usually bring the fastest growth, so the starting figure matters less than what you learn in the role.
Does location affect full stack developer pay in the UK?
It does. A city breakdown for Birmingham puts Fullstack Engineers at around £55,000 per year, with most salaries between £42,500 and £82,500. That sits below the national average, which shows how much regional employer density and living costs shape pay. Check current adverts in your target city for a more accurate local picture.
Is full stack development a good career in 2026?
Demand is holding up. IT Jobs Watch recorded 1,018 permanent UK vacancies for Full-Stack Developers in the six months to 24 September 2026, up from 439 in the same period a year earlier. Pay ranges from the low thirties to over £100,000, which leaves plenty of room to grow if you keep building your skills.
What pushes a full stack developer above the average salary?
Seniority and breadth are the usual factors. Developers who work confidently across both front end and back end are worth more to employers than specialists who cover only one side. Glassdoor reports top earners reaching £98,017 at the 90th percentile, and Indeed's upper range extends to £102,497, so the ceiling sits well above the typical figure.
