Codecademy — free coding lessons and practice (free tier)

Codecademy’s free tier provides interactive, beginner‑level coding lessons in languages such as HTML/CSS, Python and JavaScript, with hands‑on exercises and immediate feedback. It’s available to anyone in the UK who creates a free account, making it suitable for learners starting to explore programming without commitment; more advanced content and certificates sit behind paid Pro plans but the free courses remain useful and have been offered for many years. Access via the Codecademy homepage.
