Quick Answer
EU lots are divisions of a contract under Article 46 Directive 2014/24/EU. You can usually bid on multiple lots; the authority may cap how many you win. Strategic lot bidding means: bid all relevant lots, price for combinations, and position quality to win your priority lots first. For SMEs, small lots or reserved lots are the most accessible entry point. For larger companies, multi-lot combination pricing discounts are the strongest competitive lever.
Why EU Contracts Are Divided into Lots
Article 46(1) of Directive 2014/24/EU requires contracting authorities to consider dividing contracts into lots. The purpose is to:
- Enable SMEs to access large contracts they couldn't deliver in full
- Create competition among specialised suppliers for different contract components
- Reduce dependency on a single supplier for critical services
- Allow geographic division (e.g., regional lots for national programmes)
When an authority doesn't use lots, it must explain why in the contract notice or procurement documents. This "comply or explain" requirement can be challenged — if you believe unjustified single-lot structure excludes competition, this is a valid basis for a procurement challenge.
Types of Lot Structures
Geographic Lots
The contract is divided by region, country, or administrative district. Common in national framework agreements for maintenance, cleaning, security, and social care services. Bidders typically target the lots covering their operational geography. Example: A 12-lot national facilities management framework, one lot per region.
Subject Matter Lots
The contract is divided by service type or product category. Common in IT, consultancy, and professional services frameworks. Specialists bid on their core competency lots while generalists may bid across all. Example: An 8-lot consultancy framework: Lot 1 — Strategy, Lot 2 — Digital Transformation, Lot 3 — HR, Lot 4 — Finance, etc.
Quantity Lots
Large supply contracts may be divided into quantity-based lots to create multi-supplier competition. Example: Medical consumables framework — Lot 1 covers 40% of estimated volume, Lots 2 and 3 cover 30% each. Three different suppliers can win, reducing procurement risk.
SME-Reserved Lots
Under Article 20, contracting authorities can reserve contracts or lots for sheltered workshops, social enterprises, or — importantly — SMEs. When a tender includes SME-reserved lots, only SMEs can bid on those lots. This is a significant competitive advantage. Always check whether any lots have bidder eligibility restrictions.
How Multi-Lot Evaluation Works
When a tenderer bids on multiple lots, the evaluation typically follows one of three approaches:
Independent Evaluation
Each lot is evaluated completely independently. The fact that you bid on Lot 1 has no bearing on your Lot 2 evaluation. Most common for geographically-divided lots where operational context is lot-specific.
Combination Evaluation with Maximum Cap
The most strategically important variant. The authority evaluates all possible combinations of lot awards and selects the combination that maximises overall MEAT score — subject to the maximum number of lots any single winner can hold. This creates a combinatorial optimisation problem for the evaluator, and for you.
Strategic implication: If you offer a discount for winning multiple lots (e.g., 5% reduction on Lot 2 price if you also win Lot 1), the evaluation algorithm must factor this in. Document combination discounts clearly and precisely in your bid — ambiguous discount structures may be ignored by evaluators.
Sequential Evaluation
Lots are evaluated in order. The first lot is awarded, then the second is evaluated excluding the first winner (if they already reached their cap), and so on. Less common, but important to understand — being evaluated early in the sequence is advantageous when the pool of eligible bidders shrinks in later lots.
Lot Bidding Strategy by Company Size
SME Strategy: Concentrate and Specialise
- Identify your 1–2 strongest lots and submit high-quality bids focused there
- Target tenders with SME-reserved lots or below-threshold lots (€500K–€2M)
- Use the lot structure to compete with larger firms only in your core competency area
- Check whether the authority applies reduced financial standing requirements for smaller lots
Mid-Size Company Strategy: Target Complementary Lots
- Bid on 3–5 lots with natural cross-selling relationships (e.g., IT security + IT infrastructure + IT support)
- Price a combination discount that makes multi-lot award attractive to evaluators
- Ensure your technical response addresses lot-specific requirements distinctly — generic responses lose marks
Large Company Strategy: Cover All Lots, Win the Maximum
- Bid all lots to maximise combinatorial options for the evaluator
- Use sub-contractors or consortium members for lots outside core capability
- Apply graduated combination discounts that make your full-portfolio offer financially dominant
- Expect challenges from competitors and authorities on bundling — prepare justification for why multi-lot award serves the public interest
Common Lot Bidding Mistakes
- Copy-paste responses across lots: Evaluators can tell. Lot-specific methodology and examples score significantly higher.
- Ignoring the maximum award cap: If you can win maximum 3 lots, don't waste effort on 8 — focus your resources on the 3 highest-value lots.
- Unclear combination discounts: If your multi-lot discount isn't stated as a specific percentage on a specific combination, evaluators may ignore it entirely.
- Under-resourcing small lots: Small lots often have the same evaluation rigour as large ones. A thin bid on a low-value lot can prevent you from winning adjacent high-value lots in combination-evaluated tenders.
