5.31 In some cases advisers are prepared to offer success-fee based contracts or terms where an element of payment is dependent upon success. With the exception of advice on the feasibility stage of a project, NHS bodies should consider at least some success-fee element, as open-ended fee-based payments do not incentivise advisers to close deals. While success fees provide shared incentives between the NHSScotland body and its advisers, the extra risk for the advisers may result in their expectation of higher overall fees.
