Yn ychwanegol, mae bron hanner y pwerau amrywiol i wneud Rheoliadau yn ailadrodd  neu’n gwneud mân addasiadau i bwerau sy’n bodoli eisoes. Cynhwysir nifer pellach er mwyn creu hyblygrwydd er mwyn i’r categorïau neu’r diffiniadau a nodir yn y Bil gael eu haddasu, yn ôl yr angen (er enghraifft, y pŵer yn adran 9(3) i bennu pwy ddylai gael ei drin fel person byddar neu ddall at ddibenion y gofrestr). Mae’n bwysig nodi bod pwerau eraill yn disodli pwerau i wneud cyfarwyddiadau nad oeddent yn destun unrhyw broses graffu gan y Senedd neu’r Cynulliad o’r blaen. Enghraifft bwysig o hyn yw’r gallu i wneud gofynion am y ffordd y cyflawnir asesiadau gan gyfarwyddiadau o dan 47(4) o Ddeddf y Gwasanaeth Iechyd Gwladol a Gofal Cymunedol 1990. Yn olaf, mae rhai o’r rheoliadau arfaethedig yn codi statws y  gofynion a gynhwysir mewn canllawiau ar hyn o bryd. Yr enghraifft bwysicaf o hyn yw’r meini prawf cymhwysedd sy’n penderfynu pa rai o anghenion unigolyn sy’n cael eu diwallu gan awdurdod lleol.
In addition, of the various Regulation-making powers, almost half are replicating or slightly modifying powers which are already in existence. A further number are included to build in flexibility so that the categories or definitions set in the Bill can, if required be modified (for example, the power in section 9(3) to prescribe who is to be treated as deaf or blind for the purposes of the register). Importantly, other powers replace direction-making powers which were not subject to any Parliamentary or Assembly scrutiny previously. An important example of this is the ability to make requirements about the way that assessments are carried out by directions under section 47(4) of the National Health Service and Community Care Act 1990. Finally, some of the Regulations proposed are an elevation of requirements that are currently contained in guidance. The most important example of this is the eligibility criteria which are the basis for determining which of a person’s needs are met by a local authority.
