The verdict in three sentences
For a construction inspection body in Amsterdam, a premium showcase website costs EUR 9,000 to 16,000 excl. VAT in 2026, excluding the quote module. The item that changes profitability is the inspection request form by service type (EUR 2,500 to 4,000), because it qualifies the developer before the first call. With local pages per province and maintenance at EUR 120 to 250 per month, cost per lead can drop from about EUR 400 to under EUR 120 within twelve months.
What an inspection body website must do in 2026
Clients (developers, housing associations, architects, municipalities) look for an accredited inspection body that can act quickly on a specific project. They compare three things in under two minutes: services covered (structural safety, fire safety, accessibility, seismic, energy performance), service area and response time. An outdated site listing "our services" on a single page answers none of these questions.
The site should therefore have one page per inspection type, with the regulatory framework, deliverables (initial report, design review opinion, final inspection report) and a typical timeline. Energy performance certificates and airtightness tests deserve their own entry: they are frequent, low-ticket requests that open the door to larger assignments.
| Component | 2026 range (excl. VAT) | Comment |
|---|---|---|
| Premium showcase site (15 to 25 pages) | EUR 9,000 to 16,000 | Custom design, CMS, technical SEO |
| Quote request module by inspection type | EUR 2,500 to 4,000 | Conditional form: structural, fire, accessibility, energy |
| Local page per province | EUR 350 to 600 each | North Holland, Utrecht, South Holland... |
| Copywriting for service pages | EUR 250 to 450 per page | Technical content reviewed by an engineer |
| Maintenance and hosting | EUR 120 to 250 per month | Updates, backups, monitoring |
| Delivery time | 6 to 9 weeks | Content included |
Specialist agency, freelancer or WordPress theme: comparison
The choice of provider determines less the entry price than the site's ability to generate qualified requests. A EUR 60 theme set up by an intern may look sufficient, but it can neither route a request to the right account manager nor produce local pages that rank.
| Criterion | Specialist B2B agency | Generalist freelancer | Installed WordPress theme |
|---|---|---|---|
| Initial budget | EUR 11,500 to 20,000 | EUR 4,000 to 8,000 | EUR 1,500 to 3,000 |
| Form by inspection type | Included, with routing | Basic, single form | Generic form |
| Optimised local pages | 4 to 8 provinces | 1 to 2 | None |
| Timeline | 6 to 9 weeks | 4 to 8 weeks | 2 to 3 weeks |
| Qualified requests per month (estimate) | 15 to 30 | 5 to 12 | 1 to 4 |
| Main risk | Higher budget | Availability, follow-up | Invisible on Google |
The 2026 order of magnitude observed among regional inspection bodies: a site that precisely matches searches such as "construction inspection Amsterdam" or "energy compliance certificate North Holland" captures requests that tender platforms never see.
Cost per lead before and after the redesign
The right indicator is not the price of the website but the acquisition cost of an inspection request. Before a redesign, most firms pay for leads through trade fairs, networking and tender platform subscriptions.
| Indicator | Before redesign | After redesign (12 months) |
|---|---|---|
| Inbound requests via the site per month | 1 to 2 | 12 to 20 |
| Monthly marketing cost | EUR 600 | EUR 1,400 (site amortised + SEO) |
| Cost per request | EUR 300 to 600 | EUR 70 to 120 |
| Conversion rate to assignment | 20% | 25 to 30% |
| Average response time | 72 h | 24 h thanks to routing |
| Share of energy certificates in leads | 10% | 35 to 45% |

Thomas, branch director of a 22-person inspection body in Amsterdam, invests EUR 13,500 in the site, EUR 3,200 in the quote module and 6 provincial pages at EUR 450, for a total of EUR 19,400 excl. VAT. He adds EUR 180 per month for maintenance, or EUR 2,160 per year. In the first year, the site generates 14 requests per month on average, 26% of which become assignments, about 44 jobs. With an average ticket of EUR 3,800 (a mix of energy certificates at EUR 900 and structural plus fire assignments at EUR 12,000), that is EUR 167,000 of attributable revenue. Even if only a third of those jobs would have been lost without the site, the return exceeds 2.5 times the spend in year one.
FAQ
How much does a website for a construction inspection body in Amsterdam cost?
Budget EUR 9,000 to 16,000 excl. VAT for a premium showcase site, and EUR 11,500 to 20,000 with the quote module. Local pages per province add EUR 350 to 600 each.
How long does it take to launch the new site?
A complete project takes 6 to 9 weeks, including 2 to 3 weeks for technical content. Engineer review of service pages is often the bottleneck.
Do we need one page per inspection type?

Does the quote module replace the account manager?
No, it qualifies the request (project type, floor area, phase, services required) and routes it to the right person. Response time usually drops from 72 h to 24 h.
What maintenance budget should we plan?
EUR 120 to 250 excl. VAT per month for hosting, security updates, backups and small improvements, or EUR 1,440 to 3,000 per year.
