Most DIY holiday bookings are not covered by ATOL etc and this policy (combined with the cover that purchasing by credit card provides) will give you additional peace of mind.
The insolvency cover offers you compensation of up to a maximum of £5,000. Very few travel insurance policies include this travel supplier insolvency cover ( you can check if you have this with your travel insurance provider). This policy is not a substitute for full travel insurance. You must also purchase travel insurance for your trip. Supplier failure insurance offers additional cover which is not normally available through most standard travel insurance policies.
