"The reason that we give a lot of weighting to the features side of the policy is that in my view, although price is important, if you're paying slightly extra to get more benefits then that's a more valuable policy.

"The one thing that is clear is that there is a lot of difference in the fine print of policies that are available."
Bonnar said Southern Cross Travel Insurance and Travel Insurance Direct (TID) offered competitive premiums, with TID winning five stars across all of the profiles and offering some "great features", including a reverse-charge 24-hour helpline.

The Insurance and Savings Ombudsman deals with about 3000 inquiries about travel insurance a year with most resolved before becoming formal complaints last year. Most complaints related to disputes over pre-existing medical conditions and the loss of property.

Southern Cross lists five potentially costly mistakes:
• Doing activities not covered on your selected policy: Most travel insurance policies cover you for the things you're most likely to do on holiday, but when planning it always pays to check whether you are covered for specific activities.
• Forgetting to mention a medical condition when you apply: There's no obligation for travellers to declare their medical conditions when they buy a policy. But there would be no cover under all sections of the policy for any medical conditions you do not declare.
• Leaving it until the last minute: Things can happen before you leave as well as during the holiday, so would-be travellers should book their travel insurance the moment they pay any non-refundable deposits towards flights or accommodation.
• Getting "really really"drunk: Most policies do not cover claims when the direct cause was the excessive influence of alcohol, or reckless or unlawful behaviour.
• Not having it.
