The effect of a reassessment after a final assessment under s 24(1) is that compensation is payable only if the overall increase in degree of permanent is impairment is 10% or more (excepting the impairments specified in s 24(8) - fingers, toes, sense of taste and sense of smell, and loss of hearing which is covered by s 24(7A) and s 25(5)) and the reassessment is calculated under s 25(4). In this case, the amount of compensation is based on the percentage increase in WPI or combined WPI (at current rates) with the assessor being required to state what the previous WPI amounts were for each impairment. Any increase in WPI for hearing loss is included in the combined calculation.
