WCAG Accessibility Compliance for a B2B Website in London in 2026

The verdict in three sentences

Since the European Accessibility Act applicable from June 2025 and the UK's accessibility duties, accessibility is no longer optional: a non-compliant B2B website risks sanctions and above all exclusion from public and enterprise tenders. WCAG 2.1 level AA remediation costs between 3,000 and 12,000 EUR depending on the starting state, over 4 to 8 weeks. The upfront audit is the decisive step: it precisely quantifies the gap and prioritises high-impact fixes.

What the audit and remediation cost

A site built without accessibility typically shows 40 to 90 non-conformities across WCAG criteria. The budget depends directly on the number of templates and the depth of fixes.

For a simple, cleanly coded brochure site, light remediation can stay under 3,000 EUR. Conversely, an application portal with complex forms often exceeds 12,000 EUR.

The most frequent non-conformities and their priority

Not all issues carry equal weight. Some completely block a screen-reader user (high priority), others degrade experience without blocking it.

The winning strategy is to fix critical and high first (80 % of impact), then smooth out the rest in a documented multi-year roadmap.

The legal and commercial risk

Beyond potential fines, the real cost of an inaccessible site is commercial: more and more tender specifications require a compliant accessibility statement. Without it, the bid is rejected outright. For an SME bidding on public contracts or working with large groups, accessibility becomes an eligibility criterion, not a bonus.

Mini case study

Nadia, CIO of a digital services SME in London, discovers that two public tenders require an accessibility statement. Her site shows 62 non-conformities. She invests 10,000 EUR in an audit and remediation over 6 weeks. Result: the site reaches 96 % WCAG conformity, the statement is published, and the company is again eligible for a contract portfolio worth an estimated 240,000 EUR over two years. Compliance cost equals 4 % of a single contract won.

FAQ

Is accessibility mandatory for every company? The Act mainly targets players above certain thresholds and public-facing services, but tenders require it broadly. In practice, any ambitious B2B site should be compliant by 2026.

How long does remediation take? Expect 4 to 8 weeks: 1-2 weeks audit, 2-4 weeks fixes, 1 week re-test. A site with many templates or an application lengthens the timeline.

Can an existing site be made accessible without a rebuild? Yes in most cases: contrast, alt text, ARIA and keyboard navigation are fixed on the existing build. A rebuild is only needed if the code is structurally inaccessible.

What is an accessibility statement? A public document stating the conformity level, known issues and the multi-year roadmap. It proves the effort and is often required in public tenders.

Do I have to maintain accessibility over time? Yes: each new page or component can introduce regressions. A check at every release and an annual re-audit (1,500-3,000 EUR) preserve conformity.
