Dr. Matt Yardley:

We set off with what we thought the most cost-efficient way of doing this was, which was buying that product through the 300,000 home area. When the final bid is submitted, the bidder has to have absolute confidence that those inputs being taken from others are suitable for the duration of the contract.

We had some understanding of this. The bidder was concerned about taking this risk because the product is not being provided over a 25-year term. At that point, the bidder had no view on how it would be made available throughout the 300,000 premises and how it related to the intervention area. The product development was not specified, as I understand it. We have looked at future concerns about pricing, terms and conditions and range of other matters in some detail from a technical perspective.
