The authority or authorities who made a quality partnership scheme may vary the scheme if they decide that it is appropriate to do so.

The authority or authorities who made a scheme may revoke it before the end of the period for which it would otherwise remain in operation if all persons who have given an undertaking to provide a service to the standard specified in the scheme consent to the revocation of the scheme; and such consent must not be unreasonably withheld.

If the variation of a scheme under subsection (1) would require the making of a traffic regulation order, the variation is subject to the same procedure as the making of a scheme.

Any other variation of a scheme under subsection (1), or the revocation of a scheme under subsection (2), is subject to that procedure, except to the extent that the procedure is modified by regulations made under section 122.
