Paragraph 11 IndemnityI1

Subject to sub-paragraphs ‎(2) and ‎(3), if by reason or in consequence of the construction of any works authorised by this Part of this Schedule or in consequence of the construction, use maintenance or failure of any of the authorised development by or on behalf of the undertaker or in consequence of any act or default of the undertaker (or any person employed or authorised by him) in the course of carrying out such works, including without limitation works carried out by the undertaker under this Part of this Schedule or any subsidence resulting from any of these works, any damage is caused to any apparatus or alternative apparatus (other than apparatus the repair of which is not reasonably necessary in view of its intended removal for the purposes of the authorised development) or property of National Gas Transmission, or there is any interruption in any service provided, or in the supply of any goods, by National Gas Transmission, or National Gas Transmission becomes liable to pay any amount to any third party, the undertaker will—

The fact that any act or thing may have been done by National Gas Transmission on behalf of the undertaker or in accordance with a plan approved by National Gas Transmission or in accordance with any requirement of National Gas Transmission or under its supervision will not (unless sub-paragraph ‎(3) applies), excuse the undertaker from liability under the provisions of this sub-paragraph ‎(1) unless National Gas Transmission fails to carry out and execute the works properly with due care and attention and in a skilful and workman like manner or in a manner that does not accord with the approved plan.

Nothing in sub-paragraph ‎(1) imposes any liability on the undertaker in respect of—

National Gas Transmission must give the undertaker reasonable notice of any such third- party claim or demand and no settlement, admission of liability or compromise must, unless payment is required in connection with a statutory compensation scheme, be made without first consulting the undertaker and considering their representations.

National Gas Transmission must, in respect of any matter covered by the indemnity given by the undertaker in this paragraph, at all times act reasonably and in the same manner as it would as if settling third party claims on its own behalf from its own funds.

National Gas Transmission must use its reasonable endeavours to mitigate and to minimise any costs, expenses, loss, demands, and penalties to which the indemnity under this paragraph applies where it is within National Gas Transmission’s reasonable ability and control to do so and which expressly excludes any obligation to mitigate liability arising from third parties which is outside of National Gas Transmission’s control and if reasonably requested to do so by the undertaker National Gas Transmission must provide an explanation of how the claim has been minimised, where relevant.
