The verdict in three sentences
For a Dutch government agency issuing a website tender, a realistic budget for an institutional site in 2026 sits between €90,000 and €160,000, including staff training and warranty. The specification must set out three points that can double the bids: publication of legislation and reports, a news section in Dutch and English, and the choice between sovereign Dutch hosting and a public cloud. Clearly announced weighted technical criteria then let you compare bidders on quality rather than price alone.
What the specification must contain
A vague specification produces incomparable bids: one supplier prices €40,000 for a bought theme, another €220,000 for a full build. To get aligned proposals, describe the expected content and features, volumes, security requirements and what must be handed over at the end.
The key features of a government agency site are a document library (legislation, decisions, annual reports, tender notices) with search and filters, a multilingual news section, mission and organisation pages, a contact or complaints form, and open data pages if the agency publishes statistics. Dutch public bodies must also meet the legal accessibility standard and publish an accessibility statement.
| Specification item | Requirement to state | 2026 budget impact (ballpark) |
|---|---|---|
| Site structure and templates | 20 to 40 pages, 6 to 8 templates | €35,000 to €55,000 |
| Document library | Full-text search, filters by type and year, 500 documents migrated | €18,000 to €32,000 |
| Dutch and English news | Translation workflow managed in the CMS | €12,000 to €20,000 |
| Accessibility and performance | WCAG 2.1 AA, accessibility statement, lightweight pages | €8,000 to €15,000 |
| Security | SSL, web application firewall, daily backups, named accounts, BIO baseline | €8,000 to €13,000 |
| Staff training | 2 sessions of 3 hours for 8 to 10 editors, PDF guide | €4,000 to €7,000 |
| Warranty | 12 months of free fixes after acceptance | Included in the bid |
Sovereign hosting or public cloud
This question comes up in almost every tender. Hosting in a Dutch or EU sovereign data centre meets data sovereignty expectations and simplifies compliance. A public cloud with a CDN offers high availability and geographically distant backups. A mixed setup, with the site hosted in the Netherlands and backups in another EU region, is often chosen.
| Option | 2026 annual cost (ballpark) | Target uptime | Watch points |
|---|---|---|---|
| Shared Dutch hosting | €3,000 to €6,000 | 99.5% | Limited scaling during traffic peaks |
| Dedicated sovereign server | €12,000 to €24,000 | 99.8% | Administration to include in the contract |
| Public cloud with CDN (EU region) | €6,000 to €12,000 | 99.9% | Data sovereignty to justify |
| Mixed (Dutch + backup in other EU region) | €9,000 to €18,000 | 99.8% | Failover procedure to document |
| Post-warranty maintenance | €1,500 to €3,000 per month | Per SLA | Response times to contract |
Weighting technical criteria
For a public tender, the best price-quality ratio method is standard. A readable grid could give 70 points to the technical bid and 30 to price. Within the 70 points: similar public sector references (15 points), methodology and schedule (15), quality of the proposed mockup or prototype (15), team and key staff experience (15), training and knowledge transfer plan (10). Set a minimum technical score, for instance 50 out of 70, below which the price bid is not opened.
Also require delivery of the source code, admin access and documentation, so the agency does not depend on a single supplier.
Mini case study
Femke, head of communications at a government agency in Amsterdam, has a €140,000 envelope. She estimates €105,000 for design and development, €6,000 for training and €15,000 for the first year of mixed hosting, or €126,000. She keeps €14,000 as contingency.

FAQ
How much time between publishing the tender and going live?
Allow 6 to 8 weeks for the procedure and award, including the standstill period, then 12 to 16 weeks of delivery. Migrating 500 documents alone takes 1 to 2 weeks.
Should the whole site be in English?
No, translating news, citizen service pages and key notices is often enough. That costs about €12,000 to €20,000 instead of twice that for full translation.
How do we avoid abnormally low bids?
Ask for a price breakdown by lot and set a minimum technical score, for example 50 out of 70. A €35,000 bid for a 30-page site with a document library deserves a request for justification.
Who should own the domain name and hosting?
The agency itself, with named accounts and an institutional email address. The specification must require it and provide for handover of all access at acceptance.
Does the 12-month warranty cover new features?
No, it covers defects and security. Improvements fall under a maintenance contract, budgeted at €1,500 to €3,000 a month.
