Most householders don't know how the millennium bug may bite, according to Axa Insurance.
Many consumers have little idea how the bug could affect their motor, home and travel insurance policies, according to Axa's survey.
The figures also show only a third of people know house insurance policies will cover claims caused by the bug.
Also, only a quarter of drivers understand motor insurance policies will cover claims resulting from any bug-related failures.
Axa Insurance director Mark Cliff says: “While most insurance companies will not cover claims arising directly from the millennium bug, they will cover claims for damage caused as a result of the bug.”
