What is ESPD?

ESPD is an acronym for The Single European Procurement Document, which is a self-declaration of a company's:

  • Financial status
  • Qualifications – both technical and professional 
  • Eligibility in connection with compitition
  • Eligibility in connection with public procurement procedures.


The document is available in all EU-languages, and it is utilised as preliminary proof of one's eligibility in connection with public procurement procedures in EU. ESPD-documents has enabled an easier and more efficient bidding, as tenderers no longer have to go through an extensive process that involves filling out multiple forms and documents.

Fill in ESPD here!


The European Commission has a free webservice where tenderers and other parties can fill in ESPD electronically. When the ESPD has been filled in, it must be appended to the tender to the contractor. This is done in order to deliver documentation on enterprises' eligibility  to meet the standards and requirements set up for the mini-offer.

The safety of ESPD

ESPD also ensures that if a tenderer issues false information, withhold information or is unable to supplement with addidtional documentation, the respective tenderer will be excluded from the procedure or prosecuted. This ensures a fair and rightful procurement for all parties.
