Which mandatory pages does a B2B website need?

A B2B website needs at least three legal building blocks: your legal company details (name, office, contact and company number), a privacy policy and, as soon as you place non-essential cookies, a cookie policy with a correct cookie banner. Terms and conditions come on top of that and are strongly recommended, though not legally required in every case. In this article you go through, page by page, what is mandatory, what is recommended and how to put it in place on your site without harming your credibility or your conversion.

Which pages are legally mandatory on a B2B website?

For most Belgian B2B websites it comes down to three things you really need to have in order: your legal identification details, a privacy policy and a cookie policy with consent. Terms and conditions form a strongly recommended fourth element.

Concretely, the basics look like this:

• Legal company details (often in the footer plus a separate page or a mention on your contact page).
• Privacy policy (mandatory as soon as you process personal data, for example via a contact form).
• Cookie policy and cookie banner (mandatory as soon as you place more than strictly necessary cookies).
• Terms and conditions (not legally required, but highly advisable in B2B).

Good news: these pages are not a brake on your objectives. A transparent website that shows who is behind the company actually helps to build trust with your visitors. For the bigger picture around a professional site, you will find context in our guide to building a B2B website.

What must your legal company details contain?

Every company that is active online must provide clear and correct information about its identity. Under the Belgian Code of Economic Law, this covers at minimum your company name, the address of your registered office, contact details that let people reach you quickly and directly, and your company number (your CBE number).

On top of that come a few situation-dependent mentions:

• If you are VAT-registered, you state your VAT number (that is “BE VAT” followed by your company number).
• Legal entities state their legal entities register (RLE) along with the competent court.
• If your activity requires a licence or accreditation, or if you fall under a code of conduct, that belongs there too, together with the competent supervisory authority.

Many companies place these details in the footer, so that they are visible on every page, and repeat them on the contact page. Do not underestimate this: the absence of your company number or registered office can lead to fines, and it immediately undermines your credibility with a professional buyer who checks who they are dealing with.

Do you need a privacy policy?

Yes. As soon as you process personal data, and you already do that with a simple contact or quote form, you need a privacy policy under the GDPR (the General Data Protection Regulation).

A good privacy policy explains in understandable language which data you collect, for what purpose, on which legal basis, how long you keep it and with whom you may share it. The rights of the data subject also belong in it: access, correction, deletion and objection, plus how someone exercises those rights and which authority they can lodge a complaint with.

Do not copy a policy from another site. The content has to reflect your actual processing activities, think of your analytics tools, your email marketing, your CRM and any external processors. A policy that does not match what you do in practice offers no protection and can even make you more vulnerable. If you are unsure about the legal wording, have the text reviewed by a specialised lawyer.

Are a cookie banner and cookie policy mandatory?

A cookie banner and cookie policy are mandatory as soon as you place more than strictly necessary cookies. If you only use cookies that are needed to make the site work, you do not need consent. But as soon as you deploy analytics, marketing or social media cookies, you must ask for valid consent in advance.

The Data Protection Authority is clear about this: the banner must let the visitor refuse just as easily as accept, in an equal and equally visible way. A pre-ticked box or a message along the lines of “by continuing to browse you agree” does not count as valid consent. Non-essential cookies may only be placed after the visitor has actively consented.

In your cookie policy you explain which cookies you use, for what purpose, who places them and how someone can adjust their choice later. In practice you usually solve this with a consent management platform that only activates the cookies after consent and keeps the choices tidily recorded. Place the banner so that it is compliant without spoiling your first impression: an aggressive or misleading banner costs you trust and therefore leads.

Are terms and conditions mandatory for B2B?

Terms and conditions are not in themselves legally required, but for B2B they are strongly recommended. Without your own terms you fall back on general contract law, and that often works out less favourably than a set of terms that clearly delineates your rights and liability.

It is important that your terms are also genuinely enforceable, in other words that you can invoke them against your client. In B2B relationships, a mere reference to terms on your website usually does not suffice. The other party must have been able to take note of them before the agreement was concluded, and they must have accepted them. In practice that means: include your terms with your offer or order form, with a clear reference, and not only afterwards on the invoice.

Also pay attention to the content. Unfair terms, clauses that create a manifest imbalance between the rights and obligations of both parties, are also unenforceable in B2B. So have your terms drawn up or reviewed by a lawyer who tailors them to your service and your sector, rather than adopting a generic template.

Does your B2B website have to be accessible?

Since 28 June 2025 the European Accessibility Act has applied, requiring digital accessibility for a range of consumer-facing services such as e-commerce, banking and telecom. For a purely B2B website that addresses only businesses, much of that falls outside the strict scope, and there is additionally a limited exemption for micro-enterprises that provide services.

Even so, this is no reason to leave accessibility aside. The line between B2B and consumer is not always sharp in practice, the rules are evolving, and an accessible site is more usable, more findable and more professional anyway. So treat accessibility as a quality standard and not just as a legal checkbox. We list the most common pitfalls in our article on common web accessibility mistakes. If you are unsure about your exact obligations, align that with a lawyer.

How do you set this up practically on your website?

Keep it clear and findable. A workable approach:

1. Put your legal company details in the footer (name, office, company number, VAT) so that they appear on every page.
2. Create separate pages for your privacy policy, your cookie policy and your terms and conditions, and link to them consistently from the footer.
3. Add them to your footer navigation, the place where visitors and search engines expect these pages.
4. Make sure the texts match your actual processing activities and processes, and have the legally sensitive parts reviewed by a specialist.

With every new website project, or website build, we include these pages by default, so that compliance is built in from the start instead of being tacked on afterwards.

The short summary

The legal foundation of a B2B website consists of your legal company details, a privacy policy and a cookie policy with a correct consent banner, supplemented by terms and conditions that are strongly recommended. Keep the content accurate, findable in your footer and aligned with what you really do. That way you not only meet the rules, you also reinforce the trust a professional buyer needs. For the exact legal wording, it is best to work together with a specialised lawyer.
