Regulations may provide for two or more applications for a variation with respect to the same application for a maintenance calculation to be considered together.

In sub-paragraph (1), the reference to an application for a maintenance calculation includes an application treated as having been made under section 6.

An appeal tribunal considering an application for a variation under section 28D(1)(b) may consider it at the same time as an appeal under section 20 in connection with an interim maintenance decision, if it considers that to be appropriate.
