This Order is made following a review by the Secretary of State under section 148A(1) of the Social Security Administration Act 1992 (c. 5) of the general level of earnings in Great Britain with a view to determining whether, and if so by how much, the amount of the low earnings threshold for the purposes of the Social Security Contributions and Benefits Act 1992 (c. 4) should be increased for future tax years. As a result of that review, it appears to the Secretary of State that the general level of such earnings during the period from 1st October 2003 to 30th September 2004 has increased by 4.1 per cent.
