How many months of passport validity do you need for St Helena, Ascension and Tristan da Cunha?

The official source says it, word for word:
To get a visa you must have: a return ticket accommodation sufficient funds for your visit medical insurance which covers medical evacuation at a minimum value of £500,000 Apply for a visa to visit Ascension .
This is here because it is part of what you are asked for at the border, like passport validity.

What happens if you do not meet it
Airlines check validity at check-in and can refuse to board you — they face fines of 3,500 to 10,000 US dollars for carrying a passenger who is then refused entry. One denied boarding costs the traveller between 1,200 and 2,400 US dollars in lost fares, hotels and rebooking. In 2025, 1.2 million people were denied boarding or entry over passport problems, and 40% of those were validity.
Source, word for word
Check with your travel provider that your passport and other travel documents meet requirements. Renew your passport if you need to. You will be denied entry if you do not have a valid travel document or try to use a passport that has been reported lost or stolen.
