United Kingdom · Citizenship test
Start with the official handbook, Life in the United Kingdom: A Guide for New Residents. The questions are based on it, and the booking service warns that a lot of unofficial study material online isn’t approved. Then add practice tests, from the official app or the apps and sites below. We checked each one’s price and what’s free in October 2026.
The Home Office’s own guide to the test: the format, the fee, accepted ID, who doesn’t need to take it, and the link to the official booking service. It has no practice questions. Check it before you book, because the rules on ID are changing in 2026.

The official handbook from TSO, and the book every test question is based on. It comes as a paperback, a PDF or eBook, an audio CD and an audio download. Make sure you get the 3rd edition. Your local library may have a copy to borrow.
Checked October 2026
Two companion books from TSO. The study guide has practice questions for each section of the handbook, and the practice book is a set of test-style questions and answers. TSO says its practice questions aren’t the real test questions, so use them with the handbook, not instead of it.

The only official practice app, with questions from TSO based on the 3rd edition handbook. It has mock tests of 24 questions in 45 minutes, practice by topic and a progress tracker. 3.4 stars from about 1,500 ratings on the UK App Store, lower than the unofficial apps.
Checked October 2026
The most-rated unofficial app on the UK App Store: 4.7 stars from about 6,600 ratings. It has practice tests, flashcards and an audio mode, and it’s based on the handbook. It isn’t made by the Home Office. The lifetime option is the best value if you’ll use it for more than a week.
Checked October 2026
An unofficial app with over 500 practice questions you can listen to, plus a study guide. 4.8 stars from about 4,000 ratings on the UK App Store.
Checked October 2026
A free website with 40 practice tests, tests for each handbook chapter, and full mock exams. It doesn’t say who runs it, and it isn’t official, so treat anything that disagrees with the handbook with care.
Checked October 2026
Ask whether your library has the handbook or the practice books to borrow, or search its catalogue for “Life in the United Kingdom”. Make sure any copy you borrow is the 3rd edition.
