Accessibility Statement

The standard we build to

We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.2, Level AA. That is the reference standard used internationally and the one US federal agencies apply under Section 508.

To be accurate about status: btuwise has been built against those guidelines and reviewed internally, and it has not undergone a formal third-party accessibility audit or certification. We describe this as our working target and our current best effort rather than as certified conformance, because claiming more than has been verified would be the wrong kind of statement to make on this page.

What is in place

• Keyboard access. Every interactive element — navigation, search, all four calculators — is reachable and operable by keyboard, with a visible focus indicator, and a "Skip to main content" link opens each page.
• Semantic structure. Pages use real headings in order, landmark regions (header, navigation, main, footer), lists and data tables, so a screen reader can navigate by structure rather than by guesswork.
• Labelled controls. Form fields in the calculators have associated labels, and icon-only buttons carry accessible names.
• Text contrast. The design uses high-contrast near-black text on a warm off-white background; body and secondary text meet the WCAG AA contrast ratio of at least 4.5:1.
• Resizable text and responsive layout. Content reflows down to a 320 px viewport and remains readable when text is enlarged to 200%.
• Reduced motion. The site honours the operating-system "reduce motion" setting and suppresses transitions and animation when it is enabled.
• Language and titles. Every page declares its language and carries a unique, descriptive title.
• Meaningful images. Informative images carry alternative text; decorative graphics are hidden from assistive technology.
• Content, not just tools. Every calculator result is also explained in text and tables on the same page, so the information is available without operating the widget.

Known limitations

Being honest about the gaps is more useful than a clean-sounding claim:

• Third-party advertising. Ads served through Google AdSense are rendered by Google, and their markup and contrast lie outside our control. If an ad unit creates a barrier, telling us helps — we can adjust or remove placements.
• Complex comparison tables. Wide brand-comparison tables scroll horizontally on small screens. They are marked up as proper data tables, but a very wide table is harder to follow with a screen reader than a short one, and simplifying them is on our list.
• No formal audit yet. Testing to date has been internal, using keyboard navigation, browser accessibility tooling and screen-reader spot checks, rather than a full independent evaluation.

Report a barrier

If any part of this site blocks you, tell us and we will fix it. Write to info@btuwise.com with:

• the page address (URL),
• what you were trying to do,
• the browser, operating system and any assistive technology you were using.

Accessibility reports are treated as priority fixes rather than feature requests. We aim to acknowledge them within five business days, and where a fix takes longer, we will say so and offer the information you were after by another route in the meantime.

Getting the content another way

If a calculator or table is not working for you, email info@btuwise.com with your room details or the comparison you need, and we will send the result and the reasoning in plain text.

Ongoing work

Accessibility is checked when pages and components change, and this statement is updated as the site does. It was last reviewed in August 2026.
