What Is the Aggregation Rule?
This is a UK procurement term. The requirement to add together related or repeated purchases when estimating value, so a buyer cannot slice one large requirement into small pieces to stay under threshold.
What must be added together?
Related purchases and repeated requirements that together form a single need, including options and extensions.
Why does the rule exist?
To stop buyers splitting one large requirement into smaller contracts to avoid the rules that apply above threshold.
What does it mean for suppliers?
That contracts which seem small individually may actually be advertised and run under the full above-threshold rules.
