Lot Bundling
A procurement design where related lots are combined for a single award; reduces SME participation but eases buyer integration.
Definition
Lot bundling is a procurement design where related lots in a single procurement are combined for a single award rather than being awarded separately. The buyer might bundle "facilities management" + "cleaning" + "security" as one lot rather than three separate lots. Lot bundling can reduce procurement and integration overhead for the buyer and can offer suppliers more substantial contracts, but tends to favour large multi-disciplinary suppliers over SME specialists. UK procurement policy has historically pushed against excessive bundling to support SME participation, particularly under PA 2023.
How it works in practice
Lot bundling decisions are made early in procurement design and published in the contract notice; the bundling cannot be changed mid-procurement. The trade-offs are well-understood. Bundling reduces buyer integration overhead because a single supplier covers multiple service areas with one contract and one performance regime. It can also drive better commercial terms because the bundled contract value supports stronger supplier investment in mobilisation and account management. But bundling excludes SMEs who specialise in a single service area: a £20M FM/cleaning/security bundle is inaccessible to a specialist £2M cleaning SME that could compete strongly for a £5M cleaning-only lot. UK procurement policy has consistently pushed against excessive bundling: PCR 2015 guidance encouraged appropriate lot subdivision, PA 2023 strengthens this with explicit duties to consider SME participation in procurement design. Mature buyers approach bundling decisions with explicit analysis: where is the integration value real, where does it come at the cost of competitive pressure or SME access? For suppliers the implication is that bundling decisions can make the difference between bidding and not bidding; engaging through Pre-Market Engagement to shape the lot structure is high-leverage if the relevant pipeline notice signals upcoming bundling.
Common questions
Why might a buyer bundle lots?
To reduce integration overhead (one contract rather than several), to drive better commercial terms (larger contract supports stronger investment), and to simplify performance management (single supplier with single performance regime). The buyer trades these benefits against reduced competition and reduced SME access.
Does the Procurement Act 2023 restrict lot bundling?
PA 2023 places explicit duties on contracting authorities to consider SME participation in procurement design. This affects lot structure decisions: bundling that materially excludes SMEs without strong justification can be challenged. The Act does not prohibit bundling but raises the bar for justification.
Can I challenge an excessive bundling decision?
In principle yes, on grounds that the bundling unjustifiably restricts competition or excludes SMEs against the procurement policy framework. In practice such challenges are rare and difficult to succeed: courts give buyers wide discretion on procurement design. Engaging at the pipeline / pre-market engagement stage to shape the bundling decision is more effective than challenge after publication.
