(b)before the commencing date an award of that benefit has been made (whether before or after the making of the relevant statutory provision),
except as respects any period falling before the commencing date, the benefit shall become payable at the altered rate without any claim being made for it in the case of an increase in the rate of benefit or any review of the award in the case of a decrease, and the award shall have effect accordingly.

(5)Where in consequence of the making of a statutory provision altering the rate of disablement pension, regulations are made varying the scale of disablement gratuities, the regulations may provide that the scale as varied shall apply only in cases where the period taken into account by the assessment of the extent of the disablement in respect of which the gratuity is awarded begins or began after such day as may be prescribed.
(6)Subject to such exceptions or conditions as may be prescribed, where—
(a)for any purpose of any statutory provision the weekly rate at which a person contributes to the cost of providing for a child, or to the maintenance of an adult dependant, is to be calculated for a period beginning on or after the commencing date for an increase in the weekly rate of benefit; but
(b)account is to be taken of amounts referable to the period before the commencing date,
those amounts shall be treated as increased in proportion to the increase in the weekly rate of benefit.
