How to Become a Python Developer in the UK
Python developers write and maintain software in Python. Depending on the team, your work might overlap with a back-end developer, building web APIs with Django, Flask or FastAPI, or with a data engineer, writing pipelines and automation scripts. Some Python developers work on machine learning and AI products. Day to day you write code, review colleagues' pull requests, write tests and fix bugs, usually in short agile sprints.
You don't need a computer science degree, although many developers have one. Employers want to see working code, so a portfolio, a bootcamp, an apprenticeship or a junior role can all get you in.

- ML / AI Engineering - Build and deploy ML and LLM-backed services.
- Automation and Scripting - Internal tools, scrapers and ops automation.
How to become a python developer in the UK
Common routes are a computer science or related degree, the Level 4 Software Developer apprenticeship, the Level 6 Digital and Technology Solutions Professional degree apprenticeship, or a Skills Bootcamp, which is government-funded in England for eligible adults. Self-taught developers also get hired if their projects are strong. Whatever the route, learn Python properly, then SQL, Git, testing with pytest, and one framework such as Django or FastAPI. Python Institute certifications such as PCEP and PCAP can show the basics, but employers rely more on technical tests and code reviews.
- Learn core Python: data types, functions, classes, error handling, virtual environments and packaging, using the official Python tutorial or a structured course.
- Add SQL, Git and automated testing with pytest, as most junior Python job adverts ask for all three.
- Pick a direction, such as web back end with Django or FastAPI, data engineering with pandas and Airflow, or automation, and learn its main tools.
- Build three portfolio projects that solve real problems, such as an API with a database or a data pipeline, and publish them on GitHub with clear READMEs.
- Practise technical interview tasks, including coding exercises, debugging and explaining your design choices out loud.
- Apply for junior developer roles, apprenticeships and graduate schemes, and contribute to open-source Python projects to show you can work in a shared codebase.
| Route | How long | Cost | Best for |
|---|---|---|---|
| Computer science or related degree | 3 years | Tuition fee loan | School leavers and graduate schemes |
| Software developer or digital degree apprenticeship | 2-4 years | Paid by the employer | Earning while you learn |
| Skills Bootcamp or private coding bootcamp | Up to 16 weeks | Skills Bootcamps free or co-funded; private bootcamps vary | Career changers |
| Self-taught with a portfolio | 6-18 months | Low, mostly free resources | Motivated self-learners |
How long it takes
Most people take one to three years to land a first Python developer job, depending on whether they study a degree, take an apprenticeship or teach themselves. Career changers with strong projects can sometimes get a junior role within a year.
Python Developer salary in the UK
Junior Python developers typically start on around £32,000 to £45,000. Mid-level developers earn £55,000 to £80,000, and senior and lead developers can earn £90,000 to £140,000 or more. London, finance and AI or data-focused companies usually pay the most, while regional and public sector roles pay less but may offer more stability. Contractors earn day rates instead of a salary, and the IR35 rules affect how much they take home.

Python Developer FAQs
How do I become a Python developer?
Learn Python, SQL, Git and testing, choose a focus such as web development or data engineering, and build a portfolio of projects on GitHub. Then apply for junior roles, apprenticeships or graduate schemes. A degree, apprenticeship or Skills Bootcamp gives structure, but your code is what gets you hired.
Do I need a degree to be a Python developer?
No. Many employers prefer one, but plenty hire developers from apprenticeships, bootcamps or self-taught backgrounds if they pass technical tests. A strong portfolio and practical skills with frameworks, databases and testing matter more than the certificate.
How much does a Python developer earn in the UK?
Junior Python developers typically earn £32,000 to £45,000. Mid-level developers earn £55,000 to £80,000, and senior developers can earn £90,000 to £140,000 or more. Location, sector and specialism, such as data or AI, make the biggest difference.
Is knowing Python enough to get a developer job?
Rarely on its own. Employers also expect SQL, Git, testing, working with APIs and some knowledge of Linux or cloud platforms. For web roles add a framework such as Django or FastAPI, and for data roles add pandas and pipeline tools.
