Dutch public procurement runs on one main law, and it is unusually supplier friendly in one respect: it actively tries to stop buyers from asking too much of you. That is worth understanding before you bid.
Short answer: The Aanbestedingswet 2012 is the Dutch law for public procurement. It implements the EU rules in the Netherlands and is paired with the Gids Proportionaliteit, a guide that stops buyers from setting disproportionate requirements. It also pushes buyers to keep contracts accessible to smaller suppliers.
What the Aanbestedingswet covers
The law sets out which buyers must run a procurement and how they must do it, in line with the EU rules. It defines the procedures, the thresholds and the principles of equal treatment and transparency that every Dutch public tender must follow.
The Gids Proportionaliteit
This is the part suppliers should know best. The Gids Proportionaliteit, the proportionality guide, exists to prevent excessive demands, such as turnover requirements that are out of step with the contract or unreasonable numbers of reference projects. If a requirement feels disproportionate, the guide is your reference point.
Access for smaller suppliers
The Dutch rules are built to keep public contracts within reach of small and medium-sized firms, for example by encouraging buyers to think carefully before bundling work into large lots. For an SME, that makes the Dutch market worth a closer look than its size alone suggests.
The self-declaration
As across the EU, you confirm your eligibility at bid time with a self-declaration rather than a pile of certificates. In the Netherlands this is the UEA. The full evidence is asked for only if your bid is in line to win.
