When we commission new research we use the Crown Commercial Service Dynamic Purchasing System Marketplace. These are the Low Value Purchase System (LVPS) and the Research and Insights Frameworks. Only organisations registered on the selected frameworks will be eligible to submit bids. More information about these two frameworks including how to register is available here: Dynamic Purchasing System Marketplace – Supplier Registration Service (cabinetoffice.gov.uk)
The projects we commission are usually small-scale projects delivered over 1-2 years with budgets usually ranging from £25k-£100k.
