A key issue to clarify early and to agree, or reconfirm, with the Contractor is the exact date when the Contract expires. Under the WIDP Contract (Clause 3) the expiry date is defined as a specific date. However even when the Contract follows this approach it is vital to establish whether any changes to the Contract have had an impact on the expiry date. Where the Contract has a different approach to defining the expiry date (for example the expiry date may be defined as a set number of years after the Services Commencement Date) there may be even more potential for uncertainty. Procedures set out in the Contract Management Manual should highlight the importance of agreeing and logging any changes to the expiry date as and when they arise.
