Curtailment means cutting your trip short and returning to the UK earlier than planned because something happens that you couldn’t reasonably prevent.
What you should know
It only applies if you actually return to the United Kingdom earlier than planned.
Your policy may cover unused travel and accommodation costs which you have paid for before departing your home country, but cannot use because you return early (which varies based on your policy).
If you need to return early because of a serious medical emergency, contact the emergency assistance team as soon as possible.
Keep any receipts and documents that show why you had to return early, as you will need these if you make a claim.
reasons for cover and what you need to do can vary, so it’s important to check your policy documents.
