The average
The ‘condition of average’ in underinsurance states that the landlord bears a proportion of any loss if the property was insured for less than its full rebuild value.
The insurer assesses the actual rebuild cost to be £200,000, therefore only 50% of the actual value is covered. In this scenario the insurer applies ‘average’ which means only 50% of the £50,000 claim would be paid, leaving the landlord with £25,000.
