What is insurance?

Put simply, insurance is a policy designed to make sure that you are no worse off after an accident or disaster (such as a flood or burglary) than you were beforehand.
There are dozens of different types of insurance, from insurance that you have to take out by law (such as car insurance), to policies that it's a good idea to have (such as contents insurance) to those that are 'nice to have' rather than necessities.
Figures from the Association of British Insurers show that, during the recession, one in four people cancelled their home insurance. While it's a good idea to make sure you're not paying for insurance you don't need, you should always think about what would happen if disaster were to strike before cancelling any insurance policies.
