A flood of insurance concerns

Next year a government agreement with insurance companies is set to end. This agreement requires insurance companies to provide cover for homes at a high risk of flooding.

However, in June 2013, this agreement will no longer be in place and this has led to mounting concerns that it will leave thousands of home-owners with the inability either to find or afford home insurance.

The key thing with insurance is that in order for it to be provided privately, certain conditions must hold. The probability of the event occurring must be less than 1 – insurance companies will not insure against certainty. The probability of the event must be known on aggregate to allow insurance companies to calculate premiums. Probabilities must be independent – if one person makes a claim, it should not increase the likelihood of others making claims.

Finally, there should be no adverse selection or moral hazard, both of which derive from asymmetric information. The former occurs where the person taking out the insurance can hide information from the company (i.e. that they are a bad risk) and the latter occurs when the person taking out insurance changes their behaviour once they are insured. Only if these conditions hold or there are easy solutions will the private market provide insurance.

On the demand-side, consumers must be willing to pay for insurance, which provides them with protection against certain contingencies: in this case against the cost of flood damage. Given the choice, rational consumers will only take out an insurance policy if they believe that the value they get from the certainty of knowing they are covered exceeds the cost of paying the insurance premium. However, if the private market fails to offer insurance, because of failures on the supply-side, there will be major gaps in coverage.

Furthermore, even if insurance policies are offered to those at most risk of flooding, the premiums charged by the insurance companies must be high enough to cover the cost of flood damage. For some homeowners, these premiums may be unaffordable, again leading to gaps in coverage.

In light of the agreement coming to an end next year, there is pressure on the government firstly to ensure that insurance cover is available to everyone at affordable prices and secondly to continue to build up flood defences in the most affected areas. Not an easy task given the budget cuts. The following articles provide some of the coverage of the problems of insuring against flood damage.
