en.wikipedia.org/wiki/Sunday_Times_Rich_List

Recent reporting on the 2026 list says the Sunday Times Rich List includes Britons abroad, not just people resident in the UK.

• The Guardian described the 2026 list as one that “ranks the 350 wealthiest UK residents and Britons abroad.”
• The same article quotes compiler Robert Watts saying British nationals who have moved to places such as Dubai, Switzerland and Monaco “remain on our rich list — wherever they now live.”
• The National likewise reported that 111 UK citizens on the list do not live on the British mainland and that, after a residence check, people on the list “must either be British or based in Britain.”

So the article’s wording is inaccurate because it presents the Rich List as if it were restricted to people or families resident in the United Kingdom, when the current list also keeps eligible British nationals living abroad.

The claim says the Rich List is updated “annually in April.” But recent editions were published in May.

• The Guardian reported that the 2024 Sunday Times Rich List was published on Friday, May 17, 2024.
• The Guardian reported that the latest 2026 Sunday Times Rich List was published on Friday, May 15, 2026.

Because there are recent annual editions published in May, the blanket statement that the list is updated annually in April is incorrect.
