Travel insurance cancellation cover can help if the unexpected happens and you can't make your trip and should be considered when you book a holiday.
Travel cancellation cover might not make up for the disappointment of a missed holiday, but at least it'll help ease the dent in your pocket if things go wrong.
Having this protection allows policyholders to reclaim the costs of their trip up to the cover limit - minus any excess - if unforeseen circumstances prevent them from travelling.
Remember to make sure that your travel insurance policy has the appropriate level of cancellation cover.
On 21 April, 2015, Gocompare.com analysed 581 single trip travel insurance policies listed on the matrix of independent financial researcher Defaqto and found that cover and excess levels varied widely.
While 97% of the policies offered some level of cover for cancellation or curtailment of a trip as a standard feature, the cover level went from £500 to unlimited, and the excess payable ranged from £15 to £250.
A quarter of the policies studied were able to offer a discount if cancellation and currtailment cover was excluded, but you should think carefully before removing such an important part of your policy.
But often overlooked is the fact that insurance can be needed months before you even start to pack your suitcase.
Many travellers miss out on cancellation cover because they leave buying their insurance until the last minute and are therefore unable to claim if something unexpected happens.
It's a much better idea to take out travel cover soon after you book your holiday than leaving it until just before you go
Buying single trip travel insurance means that your cover starts straight away, not on the first day you go.
If you prefer an annual or multi-trip policy, you need to remember that your cover only starts on the day that you request - if that's not until the first day of your holiday, you won't get the benefits of cancellation cover before that.
Gocompare.com suggests that anyone planning a trip should think about arranging their cover sooner rather than later, because leaving it to the last minute might mean losing valuable protection.
"Cancellation cover is an important and often overlooked benefit of travel insurance," said insurance expert Jeremy Cryer.
"It helps hundreds of thousands of consumers reclaim cancelled holiday costs every year.
Reasons to cancel your holiday might include:
It's likely that your insurance provider will need to see proof to back up your claim, such as medical records or an official letter.
Claims might not be met if you were under the influence of drink or drugs at the time of the incident you're claiming for.
Remember also that you can't take out a policy after an event has already happened and then make a claim.
"It's important to remember that you cannot insure yourself against an event taking place that you were already aware of," said Cryer.
"If a family member becomes seriously ill in the run-up to your holiday, you can't then take out insurance with the intention of cancelling your trip.
"Likewise you cannot take out a policy after hearing about potential serious disruption to your travel plans - such as that caused by striking airline staff or a natural disaster - and expect to be able to claim for deciding to abandon your holiday.
"Your insurer will check when you were first aware of the potential disruption to your holiday before deciding whether your claim is genuine.
"It's therefore a much better idea to take out your travel cover soon after you book your holiday than leaving it until just before you go."
