As an expert, I am going to say ‘it depends’. I have written an article on this which appeared in the NEC3 User’s Newsletter. However, you can find it direct at the bottom of this web page :

As Jon says - it really does depend on a number of factors such as:

  1. clients attitude to risk and requirement for cost certainty
  2. complexity and uncertainty of the works
  3. known relationship between the Parties

You need to pick the right percentage to incentivise to achieve the required output. To little benefit and the Contractor will not be incentivised to cut costs and this will be also reflected in a higher tender price. Too good incentives and the client may end up paying more than they might have.
