A procurement lot is a defined part of a larger tender that can be evaluated and awarded separately. A buyer can divide a requirement by product, service, geography, customer group, delivery stage or another practical boundary.
Suppliers may be allowed to bid for one lot, several lots or all lots. The contract notice and procurement documents state the permitted combinations.
Why buyers divide contracts into lots
Lots can match the structure of the market and make participation possible for specialist or smaller suppliers. They can also separate requirements that need different capabilities.
Single contract
Combined requirement
Products, services or regions remain in one scope.
One tender per supplier
Each bidder must cover the complete requirement.
One award
The selected supplier receives the combined contract.
Simple contract structure, but suppliers unable to cover the full scope cannot participate alone.
Contract divided into lots
Defined lot scopes
Each lot covers a stated product, service, area or delivery package.
Permitted lot choices
The documents say whether suppliers may bid for one, several or all lots.
Separate or combined awards
Different suppliers can win different lots, subject to the published rules.
Participation can be narrower, while evaluation and delivery remain controlled by lot-specific requirements.
The notice and procurement documents determine whether lots are evaluated separately and whether combinations are permitted.
The documents set the bidding rules
For each lot, check:
- the subject and geographic scope;
- the estimated value or quantity;
- lot-specific mandatory requirements;
- selection and award criteria;
- whether one supplier may bid for several lots;
- any limit on the number of lots one supplier may win; and
- whether the buyer may combine lots into one award.
Do not assume that a requirement stated in one lot applies to another. Some documents contain common conditions followed by separate technical schedules, while others repeat the full requirement for each lot.
Lot value and total procurement value
The value of one lot does not necessarily determine the legal regime. Under EU rules, the buyer generally considers the total estimated value of all lots when assessing the relevant procurement threshold. Limited exceptions can apply to smaller lots within the conditions set by the directive.
For suppliers, the lot value is more useful for estimating the scale of the potential contract. Check whether the figure is an estimate, maximum ceiling, annual value or total value across all available extensions.
How evaluation can work across lots
The buyer may apply the same award criteria to every lot or publish different criteria for different lots. The documents can also explain how the buyer resolves a situation in which one supplier ranks first for more lots than it is permitted to win.
Where combined awards are allowed, the buyer may compare a package of lots with the result of awarding them separately. That method must be stated in the procurement documents.
Choosing which lots to bid for
A supplier should assess each lot on its own scope and evidence requirements. Relevant questions include:
- Can the supplier meet every mandatory requirement for this lot?
- Does the required capacity fit alongside other lots and current commitments?
- Can references and personnel be reused across lot applications?
- Do volume assumptions support the proposed price?
- Would winning several lots create concentration or mobilisation risk?
Bidding for every available lot can weaken a response if the supplier's evidence only fits part of the requirement. A narrower bid can be more credible when the procedure permits it.
Lots and subcontracting are different
A lot defines what the buyer may award as a separate contract. Subcontracting defines how the winning supplier may organise delivery. A supplier can bid for one complete lot and still use permitted subcontractors within it.
The procurement documents control both questions. Review any restrictions on critical tasks, consortium participation and subcontractor disclosure alongside the lot rules.
