| 4.     | The      Authority did not receive any objections relating to the proposed modification.      Three Licensees made a representation suggesting that changes be made to      paragraph 3 of SLC 4C to incorporate a requirement on the Authority to      consult on the initial format of the reporting requirement and for consent      to be given by the Licensees to the Authority (such consent not be unreasonably      withheld) for any amendment made to that requirement thereafter. Four other      Licensees supported that suggestion. Another two Licensees made a representation      suggesting that the Authority consult the Licensees on the initial format      of the reporting requirement and any subsequent amendment. Two licensees      made a representation that the requirement in paragraph 2 of SLC 4C not      to discriminate should be limited to where this would have an effect on      competition. All the representations made by the Licensees are available      on theOfgem website at www.ofgem.gov.uk. |

| 5.     | The Authority gave full consideration      to all of the representations. Paragraphs 3 and 4 in the attached schedule      have been amended to address the concerns of the Licensees regarding amendments      to the information requirement. The Authority retains the power to request      the information in the required format on a yearly basis and at such other      time (in the required format) as it considers necessary. The Authority      does not consider that a requirement to consult on the initial format would      add any value as such consultation has already occurred. Paragraph 2 has      been amended slightly in response to the comment to reflect the Authority's      intention that the licensee shall not discriminate in the level of provision      delivered, rather thanthe means of providing the service.                                                                                                                                                                                           |
