Although 'up to date' has the dictionary meaning of 'including the latest information, or based on or using the newest information, methods, etc' it can also, particularly in British English, have the meaning of not being behind or late with some kind of regular or scheduled thing, such as rent or debt payments, or in a medical sense, with vaccinations or other treatments. These are all British examples:
Hopefully everyone knows that rent is a priority. If you fall behind
on payments and don’t make an arrangement to get back up to date it
could ultimately mean eviction from your home.
I got a letter saying one of my loans had gone into arrears and that I had to bring payments up to date, pay an arrears fee, or face legal action.
If you're only travelling to countries in northern and central Europe,
North America or Australia, you're unlikely to need any vaccinations. But it's important to check that you're up-to-date with routine
vaccinations available on the NHS.
