Questions, answered

How much does Python web development cost in the UK?

Every project starts with an £8k fixed-price discovery, then runs in four-week cycles at £15–25k per month. Use the estimator above for a range that fits your scope.

Should we use Django or FastAPI?

Django for products with users, an admin and content. FastAPI for high-throughput APIs and model-serving services. Many of our clients run both side by side.

Can you upgrade an old Django 2.x or 3.x project?

Yes. We upgrade one supported release at a time, add tests where they are missing and keep the site live throughout.

Do you provide Python developers for hire or white-label work?

Yes. Senior engineers can join your team on a monthly basis or work under your agency brand with your clients.

Do you work with the public sector?

Yes. We build to WCAG 2.2 AA and the GOV.UK Service Standard, and work within your procurement route.
