Make sure you compare both the level of cover you will have under your policy and how much excess you will need to pay.
It's important to consider all the activities you might take part in on an extended trip, and check the level of cover for these. While you can't cover for every situation, as plans can and do change - particularly on a long trip - you want to make sure your insurer is aware of your general plans. This way, you'll get the right level of cover for you.
As with standard travel insurance policies, the level of cover you'll get will vary significantly between providers, so make sure you read the small print. For example, are you planning on indulging in adrenalin activities while away, such as bungee jumping, or white water rafting?
These are considered to be 'adventurous sports' that are higher risk for an insurer, so while some will cover a wide range, others won't.
Also, check whether the policy offers single or family cover depending on whether you're travelling with kids or solo - or perhaps as a couple. Different insurers offer various options.
At TravelSupermarket, we recommend the following as the minimum level of cover you should look for in a policy:
Medical expenses - Medical cover should be around £2million, and should also cover the cost of emergency repatriation.
Personal liability - Cover for personal liability should amount to around £1million.
Cancellation Cover - Cancellation cover should be either £3,000 or enough to cover the total cost of your holiday, including the cost of any prepaid excursions.
Baggage Cover - Minimum level of baggage and possessions cover should be £1,500.
Holiday Money - Minimum cover will usually allow for £250 worth of cash - if you plan to carry more with you ensure your policy reflects that.
Policy Excess - This should ideally be under £100.
Scheduled Airline Failure - Cover for this should be included, along with end supplier failure if you are not travelling on an ATOL backed package holiday.
Delay Cover - For example, this could be £20/hour for first 12 hours.
Search and rescue cover can also be included in a long-term policy. However, be aware that if you are planning on becoming an intrepid explorer and venture far off the beaten track, you may find you're not covered.
