The Average Full Stack Developer Salary
Across the UK, the average full stack developer salary sits at roughly £57,000, with a median close to £60,000. Because full stack developers work across both the front end and the back end, they command more than single-discipline developers at the same level, and demand in eCommerce keeps pushing the top of the range higher.

Salary by Seniority
Development has a clear ladder, and because output is measurable, strong engineers move up quickly. Here is how the pay progresses at each stage.
Junior · £30k to £42k
You build features under supervision, learn the codebase and the stack, and ship small pieces end to end. A strong portfolio and public code speed up the climb.
Mid-level · £48k to £65k
You own features across the front and back end, work independently, and start influencing technical decisions. This is where the full stack developer salary really opens up.
Senior · £65k to £90k
You lead on architecture, mentor others, and own delivery of significant systems. Cloud, performance and system-design skills push you toward the top of the band.
Lead / Principal · £90k to £120k+
You set technical direction, lead a team, and own the roadmap for platform and engineering. At larger brands and in London, total pay pushes well past £120,000.
Pay by Stack
The technologies you know shape your pay. In eCommerce, JavaScript stacks and modern cloud experience command a premium, while legacy platforms can too where skills are scarce. Here is how mid-to-senior London pay compares across common full stack combinations in 2026.
| Stack | London range | Notes |
|---|---|---|
| MERN / Node & React | £60k to £100k | JavaScript end to end, high demand |
| Next.js / headless | £65k to £105k | Composable commerce, premium skills |
| PHP / Laravel | £50k to £85k | Common in eCommerce and Magento |
| .NET / Python | £55k to £95k | Enterprise and data-heavy platforms |

What Affects Your Pay
Two developers with the same title can be £20,000 apart. These are the factors that decide where you land in the range.

Often, yes. Because full stack developers work across both the front and back end, they tend to earn a little more than single-discipline front end developers at the same level.

Modern JavaScript stacks pay best in eCommerce. Next.js and headless commerce skills top the range at £65,000 to £105,000 in London, followed by MERN or Node and React. PHP and Laravel remain common and well paid where Magento or bespoke platforms are involved, and .NET or Python suit enterprise and data-heavy builds.
