## Description
The framework has the ability to award contracts through restricted quick quotes, open quick quotes, mini competition and direct award. Call-off contracts can be either fixed cost or cost reimbursable. 
Mini-Competition 
Where mini-competition is used, this is to be via the e-tender portal and must include all suppliers on the applicable lot. Each mini competition will be restricted to only one Lot. Should requirements at call-off not have been priced at point of framework creation, mini-competition should be held allowing all suppliers in the applicable Lot to price, accordingly, providing the additional requirement fits within the overall subject matter of the applicable Lot. Mini-competition criteria must not repeat qualification questions. The evaluation criteria must however comprise of the following, with weighting allowances adhered to: 
Evaluation Criteria Range 
•	Pricing 5-90% 
•	Technical 5-90% 
•	Social Value 5-90% 
Mini competitions can be ran using both the Open Procedure and the Competitive Flexible Procedure under the Procurement Act 2023, where the call-off is above threshold. 
The Framework Agreement permits contracts to be awarded by direct award. UKNNL may award a contract directly to a Supplier where this is justified by the requirement for continuity of service, demonstrable value for money, and compliance with applicable procurement legislation.
A direct award can be made to a supplier for the continuation of existing services. This approach is considered appropriate where the supplier has established knowledge, experience, systems integration, and operational capability that are critical to the effective delivery of the services and where a change of supplier would result in disproportionate cost, disruption, delay, or operational risk.
Further justifications for Direct Award can be found below:
•	It secures the uninterrupted continuation of critical services.
•	The requirement consists of substantially similar or repeat services already being delivered by the current supplier.
•	A change of supplier would require significant transition activity, resulting in additional cost, resource burden, loss of operational knowledge, and increased delivery risk.
•	The supplier is already integrated within existing governance, processes, systems, and delivery arrangements.
•	The proposed award represents value for money when considering both contract costs and the costs and risks associated with supplier transition.
•	The award supports efficient service delivery and maximises public benefit.
UKNNL has assessed that awarding the contract to the current supplier represents the most advantageous commercial outcome and is consistent with the Framework terms and/ or the principles set out within Schedule 5 of the Procurement Act 2023 relating to circumstances where supplier continuity, technical knowledge, interoperability, or the procurement of similar services provide a lawful justification for direct award. 
The Procurement Lead shall ...
