How this site works

Every guide is built from primary sources and links to them. Anything time-sensitive is dated and re-checked when the rules change. Some links earn a commission, which never decides what gets recommended, the editorial policy and affiliate disclosure spell out exactly how.

This is general information about how things work in the UK, not financial, tax or legal advice. For your own situation, speak to a qualified accountant.
