6.1 Sub-hubco must implement a required Low Value Change so as to minimise any inconvenience to the Authority and, subject to paragraph 10.2 of this Section 2 (Low Value Changes), within the timescale specified in the notice given by Sub-hubco pursuant to paragraph 3 of this Section 2 (Low Value Changes) (or agreed by the parties pursuant to paragraph 5 of this Section 2 (Low Value Changes)).
6.2 Sub-hubco shall notify the Authority when it considers that the Low Value Change has been completed.
6.3 If Sub-hubco:
6.3.1 fails to give a notice to the Authority in accordance with paragraph 3 of this Section 2 (Low Value Changes) within fifteen (15) Business Days of the date of the Authority Change Notice; or
6.3.2 gives a notice pursuant to paragraph 3 of this Section 2 (Low Value Changes) to which the Authority has objected pursuant to paragraph 5 of this Section 2 (Low Value Changes) on any ground other than the cost of the Low Value Change, the parties have not reached agreement as to how the Low Value Change is to be implemented and the objection has not been referred to the Dispute Resolution Procedure; or
6.3.3 gives a notice pursuant to paragraph 3 of this Section 2 (Low Value Changes) to which the Authority does not object pursuant to paragraph 5 but then fails to fully implement the Low Value Change within ten (10) Business Days after the timescale specified in that notice or agreed in accordance with paragraph 5 of this Section 2 (Low Value Changes),
then, subject to paragraph 10.3 of this Section 2 (Low Value Changes), the Authority may notify Sub-hubco that the Low Value Change Notice is withdrawn and, following such notification, may procure the implementation of the Low Value Change without further recourse to Sub-hubco, but the Authority must ensure that the Low Value Change is carried out in accordance with Good Industry Practice and to the standards that would have applied to Sub-hubco if it had implemented the Low Value Change.
