Technical information about this website’s accessibility

British Antarctic Survey is committed to making its website accessible, in accordance with the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018.

Compliance status

This website is partially compliant with the Web Content Accessibility Guidelines version 2.1 AA standard, due to the non-compliances and exemptions listed below.

Non-accessible content

The content listed below is non-accessible for the following reasons.

Non-compliance with the accessibility regulations

Most older PDF documents are not fully accessible to screen reader software. This fails WCAG 2.1 success criterion 1.1.1 (non-text content). We plan to replace PDFs with a text-based alternative by march 2022.

Some of our older embedded videos do not have captions. This fails 1.2.2 Captions (Prerecorded) and (Video) 1.2.3 Audio Description or Media Alternative (Prerecorded). We have added auto-generated captions to our YouTube videos that do not have captions written by humans. We plan to add captions to all of our existing videos by March 2022.

Some links do not have discernible text. This fails 2.4.4 Link Purpose (In Context) and 4.1.2 Name, Role, Value (Link). We plan to rectify this by March 2022.

Not all frames have title attributes. This fails 2.4.1 Bypass Blocks (Frames) and 4.1.2: Name, Role, Value (Frames). We plan to rectify this by March 2022.

Content that’s not within the scope of the accessibility regulations

Live video

We do not plan to add captions to live video streams because live video is exempt from meeting the accessibility regulations.

What we’re doing to improve accessibility

The table below shows the items where our website fails to conform to the WCAG 2.1 AA guidelines and also has a timeline of when we aim to fix these issues.

Target Date Item Status
October 2020
ARIA hidden element must not contain focusable elements –
This has been spotted on the cookie notice which uses an incorrect/redundant method hiding with an ARIA property and
CSS combined (Sitewide in cookie notice).
October 2020
ARIA attributes must confirm to valid values – The tabs interface doesn’t use correct ARIA properties which can
cause confusion for users with assistive technology making a distinction between different visibility states,
properties and role inheritance.
October 2020
Certain ARIA roles must container particular children – The carousel on the homepage uses ARIA properties
incorrectly resulting in confusing and potentially a barrier to users with assistive technology from accessing
content in the carousel (Carousel on homepage).
October 2020
Buttons must have discernible text – Throughout the site the button(s) highlighted has no discernible text and
doesn’t used the correct code for a button: meaning that users with assistive technology may not be able to
understand what this is for and unable to use it to search the site. (Sitewide in navigation search button)
October 2020
Elements must have sufficient colour contrast – Throughout the site many links have insufficient text colour with their background (Homepage, Navigation on tablet overflows).
October 2020
Focus indicator missing for skip to main content link – The skip to main content link isn’t visible on focus and remains hidden when using a keyboard to navigate the page (Homepage).
October 2020
Inaccessible by keyboard and no conforming alternate on carousel – The buttons which control the carousel aren’t accessible using a keyboard so therefore the contents within this section cannot be accessed without a mouse which is a dependency for users with vision or motor disabilities. (Images page carousel).
October 2020
Informative CSS image is missing text alternative – There are multiple icons without text for social media links (Sitewide in social media links).
October 2020
For <input> elements must have labels – Ensures every form element has a label (People page)
October 2020
IDs used in ARAIA and labels must be unique – Document has multiple elements referenced with ARIA with the same id attribute: newsDropdown (People page)
September 2020
Homepage <title> does not identify purpose of page – There appears to be a redundant hyphen preceding the website name
here which screen readers will read out and may confuse users.
June 2021
Images must have alternate text – Fix by reviewing all featured images to have alternative text to relay information to blind users about the image’s contents and purpose. If the image is for decorative purposes only then check the code used here includes an empty ALT property (Sitewide).
Complete. We have taken steps to implement AI generated alt text by default on all new images that get added, these can then be overwritten by our admin users if the alt text is not fully suitable. We have also retrospectively added alt text to existing images using a combination of AI and manually checking.
March 2022
Ensure PDFs either are converted into or have a text-based alternative.
March 2022
<video> elements must have captions (Sitewide)
March 2022


Links must have discernible text (Sitewide)
March 2022
Frames must have title attribute – Iframe(s) missing a title attribute which is necessary to describe the contents inside when navigating the page using a screen reader (Sitewide).
