6.12 The Government believes, however, that improvements can be made to the previous model, in particular for insurances in the operational phase of projects, which may offer improved value for money. The public sector will be allowed to take a greater share in the risk of market changes in insurance costs, thus reducing the need for contractors to build up reserves against them. It will also be acceptable to make changes to the balance of certain risks in projects in their operating phase to allow the procuring authority to cover these, instead of the contractor insuring them in the market.
