What is a web agency?

A web agency designs, builds and maintains websites. KernWeb covers the whole chain: strategy, custom design, Wagtail development, SEO and maintenance.

How much does a website cost in Brussels?

Our packages start at €5,000 and go up to €20,000 for an advanced custom site. We break it all down in our articles.

Do you build custom sites or use templates?

100% custom. Every design is unique; we never use a template. See our website creation offer.

Do you work outside Brussels?

Yes, across Belgium and French-speaking Europe. Projects run remotely; for an EU company, invoicing uses the reverse-charge mechanism.

Do you redesign existing sites?

Yes. We redesign and migrate existing sites without losing the rankings you've earned.

Let's talk about your project

What our web agency does

Website creation

Custom-built websites with a unique design, developed on the Wagtail CMS. No template, and you own the code.

Redesign & migration

Is your site dated or slow? We redesign and migrate it without losing your search rankings.

SEO & performance

Technical SEO, Core Web Vitals and accessibility: every site is optimised for Google and for your visitors from day one.

And also: managed hosting, security maintenance, training so your teams can edit content on their own, and custom integrations (CRM, payment, API).

Website creation, our core business

Most of our projects are website creations in Brussels: a site built as a sales tool, not a brochure. Conversion-driven design, SEO structure, and content that answers your customers' real questions.

We work on a quote basis, with transparent prices from €5,000 and a fixed fee once the scope is agreed. Based in Brussels? The Prime Digitalisation grant can cover 25 to 70% of your project.

A website for your industry

We design sites tailored to the needs of each profession: accounting firms · real estate agencies · architects · restaurants & horeca · non-profits · recruitment firms · wellness centres · telecom & IT · engineering firms · care homes · print shops · cultural institutions.

Why choose a web agency in Brussels

A local agency means a partner who knows your market, speaks your language (FR and EN) and can meet in person. It also means access to the Brussels Region's Prime Digitalisation grant for eligible companies.

Behind KernWeb: 10+ years of KERN-IT engineering, 50+ clients and 100+ delivered projects, rated 5 stars on Google. We don't subcontract: design, development and SEO are done in-house.
