On 1 March 2011, the European Court of Justice decided insurance companies who used gender as a risk factor when calculating insurance premiums were breaching EU equality laws. The Court ruled that car-insurance companies were discriminating against men. However, in some places, such as the UK, companies have used the standard practice of discrimination based on profession to still use gender as a factor, albeit indirectly. Professions which are more typically practised by men are deemed as being more risky even if they had not been prior to the Court's ruling while the converse is applied to professions predominant among women. Another effect of the ruling has been that, while the premiums for men have been lowered, they have been raised for women. This equalisation effect has also been seen in other types of insurance for individuals, such as life insurance.
To reduce the insurance premium, the insured party may offer to pay a higher excess (deductible) than the compulsory excess demanded by the insurance company. The voluntary excess is the extra amount, over and above the compulsory excess, that is agreed to be paid in the event of a claim on the policy. As a bigger excess reduces the financial risk carried by the insurer, the insurer is able to offer a significantly lower premium.
