Social Security Act 1975

1 For the purposes of section 57 of this Act, the extent of disablement shall be assessed, by reference to the disabilities incurred by the claimant as a result of the relevant loss of faculty, in accordance with the following general principles :—

(a) save as hereafter provided in this paragraph, the disabilities to be taken into account shall be all disabilities so incurred (whether or not involving loss of earning power or additional expense) to which the claimant may be expected, having regard to his physical and mental condition at the date of the assessment, to be subject during the period taken into account by the assessment as compared with a person of the same age and sex whose physical and mental condition is normal;

(b) regulations may make provision as to the extent (if any) to which any disabilities are to be taken into account where they are disabilities which, though resulting from the relevant loss of faculty, also result, or without the relevant accident might have been expected to result, from a cause other than the relevant accident;

(c) the assessment shall be made without reference to the particular circumstances of the claimant other than age, sex, and physical and mental condition ;

(d) the disabilities resulting from such loss of faculty as may be prescribed shall be taken as amounting to 100 per cent. disablement and other disabilities shall be assessed accordingly.
