EU Procurement Insurance and Performance Bond Requirements 2026: What Suppliers Must Provide

Standard Insurance Requirements by Contract Type

Performance Bonds and Financial Guarantees

Performance bonds — guarantees issued by a bank or surety company that the contracting authority can call upon if the supplier fails to perform — are standard in construction contracts above €500K and increasingly required in services contracts. Key structures:

• On-demand (unconditional) bond: The guarantee can be called by the contracting authority on first demand, without requiring proof of default. Common in construction (5–10% of contract value) and large IT projects. The surety or bank pays immediately and seeks recovery from the contractor separately — maximum protection for the buyer, maximum financial exposure for the supplier.
• Conditional bond: Requires the contracting authority to demonstrate the contractor's default before the guarantee can be called. Preferred by suppliers but less common in high-risk construction or cross-border contracts where enforcement of the default condition across jurisdictions is complex.
• Advance payment guarantee: Where contracts include advance payments (common in construction, 10–30% of contract value), contracting authorities require an equivalent bank guarantee securing the advance. The guarantee reduces pro-rata as work is completed and the advance is earned off.
• Retention bond: An alternative to the contracting authority withholding 5–10% of progress payments as retention — the supplier provides a retention bond of equivalent value, allowing cash flow to be maintained during the contract execution period.

Proportionality: When Insurance Requirements Are Unlawfully High

Article 58(3) of Directive 2014/24/EU requires that all financial capacity and insurance requirements be proportionate to the subject matter of the contract. This proportionality test applies to insurance just as it applies to turnover thresholds. A contracting authority demanding €10M professional indemnity cover for a €200K consultancy contract is disproportionate — the risk exposure the authority faces simply does not justify that level of cover, and the requirement functions as an unjustified barrier to competition.

Performance bonds follow a similar proportionality logic. The standard market range is 5–10% of contract value, with the bond released at practical completion. A bond requirement of 20% for a routine services contract would be challengeable. The CJEU and national courts have found violations where:

• PI insurance requirements exceed the contract value for low-risk services
• Performance bond percentages exceed 10% for standard works contracts without specific risk justification in the contract documents
• Insurance must be held with specific national insurers (violates EU single market principles)
• Cyber insurance minimums are set without reference to the data classification level of information actually processed under the contract

Where requirements appear disproportionate, raise a formal clarification question during the tender process — citing Article 58(3) and requesting the risk justification. If the authority does not reduce the requirement, this can be the basis for a procurement challenge after award. Practically: the ESPD permits self-declaration of insurance commitments; actual policy documents are only required at contract award stage, giving suppliers flexibility to obtain upgraded coverage between bid submission and award.
