This paragraph applies where, on a review under subsection (2) of section 148 of the Social Security Administration Act 1992 (c. 5) (review of general level of earnings obtaining in Great Britain) in a tax year, the Secretary of State concludes that the general level of earnings obtaining in Great Britain (“the new level”) exceeds the general level at the end of the period mentioned in paragraph (a) or, as the case may be, the date determined under paragraph (b) of that subsection (“the old level”).

The Secretary of State must make an order under sub-paragraph (7) of paragraph 26 which has the effect of increasing the amount specified for the purposes of that sub-paragraph by the percentage by which the new level is greater than the old level.

The order must provide for the increase to have effect on and after the 1st April next following the end of the tax year to which the review relates.
