Website Accessibility in Singapore: WCAG 2.2 for Business Sites

Short answer: Singapore has no law that requires a private business website to meet an accessibility standard. Government digital services must meet WCAG Level AA under GovTech's Digital Service Standards, and the Enabling Masterplan 2030 targets every high-traffic government site conforming by 2030. For a business site the practical standard is WCAG 2.2 AA, GovTech's free Oobee scanner finds most failures, and fixing a typical 10-page site takes 1 to 3 days.

What does Singapore require and what does it recommend?

Facts, with dates.

• Government services: required. GovTech's Digital Service Standards, last updated 26 March 2026, incorporate WCAG Levels A and AA and apply to agencies and the industry partners that build their services. MDDI's parliamentary reply of 12 November 2024 names the target: all high-traffic government websites conforming to WCAG 2.1 AA by 2030.
• The Enabling Masterplan 2030. MSF's EMP2030, the 2022 to 2030 plan, sets the goal of all high-traffic government websites being fully accessible by 2030, up from 61% at the time. It has 29 recommendations; none places a legal duty on private websites.
• Private sector: recommended, not mandated. MDDI's reply of 5 December 2024 describes engagement with private firms, a May 2024 Co-Creation Lab with over 90 participants, and the release of Oobee, GovTech's open-source accessibility tester, free for any organisation.
• The PDPA and the Building Control Regulations govern data and buildings, not web content.

What this means for a business: no fine and no complaint mechanism specific to websites. The reasons to meet the standard are practical. Customers over 50, customers with low vision or limited dexterity and screen reader users are part of every Singapore market. Government tenders and large clients ask for WCAG conformance. Most fixes also improve mobile use and search indexing.

What does WCAG 2.2 AA mean in plain terms?

WCAG 2.2 was published by the W3C as a Recommendation on 5 October 2023 and updated 12 December 2024. Level AA is the level governments and procurement specify. The W3C summary of what is new lists 9 added criteria and one removed, 4.1.1 Parsing.

The criteria group under four principles. For a business site they reduce to:

• Perceivable. Every image has a text alternative. Text has a contrast ratio of at least 4.5:1, or 3:1 for text of 18 point or 14 point bold. Content works at 200% zoom and on a 320 pixel wide screen. Video has captions.
• Operable. Everything works with a keyboard alone. Focus is visible and not hidden behind a sticky header (new in 2.2). Buttons and links are at least 24 by 24 CSS pixels or spaced apart (new in 2.2). Anything done by dragging can also be done by tapping (new in 2.2). Nothing flashes more than three times a second.
• Understandable. The page language is declared. Form fields have visible labels, errors name the field and the fix, and information already entered is not asked for again (new in 2.2). Help, such as the contact link, sits in the same place on every page (new in 2.2). Logins do not depend on memory or puzzles (new in 2.2).
• Compatible with assistive technology. Custom controls expose their name, role and state so a screen reader can announce them.

12 checks on a business site

Run these on the homepage, one service page and the contact page. Automated tools catch about half; the rest need a person.

The first six match the failures WebAIM finds most. Its 2026 WebAIM Million analysis of 1,000,000 home pages, February 2026, found detectable WCAG 2 failures on 95.9% of pages, an average of 56.1 errors per page, and six issue types making up 96% of errors: low contrast text (83.9% of pages), missing alt text (53.1%), missing form labels (51%), empty links (46.3%), empty buttons (30.6%) and missing document language (13.5%).

Tools, all free:

• Oobee, GovTech's scanner, MIT licensed, built on axe-core, reports Must Fix and Good to Fix findings against WCAG 2.2.
• Lighthouse in Chrome, whose accessibility score is a weighted average of axe-core audits. Its own documentation lists what it cannot test: keyboard order, focus traps, custom controls, visual meaning.
• A keyboard and a phone, for checks 7 to 12.

A Lighthouse score of 100 means the automated checks passed, not that the site is accessible. Checks 7 to 12 are the ones that stop a real visitor. The wider audit method is in website audit checklist.

What does it cost to fix a typical 10-page site?

Estimates, for a site on a modern stack where the developer can edit the templates.

Total: 1 to 3 working days where templates are editable. On a builder or a theme with locked components, some items cannot be fixed, and the cost becomes the rebuild. A rebuild on Next.js from a fixed-price studio starts at S$2,000; accessibility is then a build requirement rather than a retrofit, because colours, forms and focus styles are set once in the template and inherited by every page. The hosting and security side of that stack is described at website infrastructure.

Accessibility checklist

• Colours pass 4.5:1 for body text and 3:1 for large text and interface borders.
• Alt text on every informative image; empty alt on decorative ones.
• Visible labels on every field; errors name the field and the fix; no repeated entry.
• One H1 per page, headings in order, page language declared.
• Keyboard: skip link, visible focus, logical order, nothing hidden under sticky elements.
• Targets 24 by 24 pixels or spaced.
• No drag-only interactions; no login puzzles.
• Captions on video; no autoplay with sound; nothing flashing.
• Help and contact in the same place on every page.
• Scanned with Oobee and Lighthouse, then checked by a person on a keyboard and a phone.
• Re-checked after every design change.
