Accessibility Statement

We are committed to creating an accessible experience for all users

Last Updated: 12th March 2026

Health Data Research UK (HDR UK) is committed to making our website accessible for everyone. We aim to meet the Web Content Accessibility Guidelines version 2.2 AA standard where we can. These guidelines are about making web content more inclusive to as many people as possible.

This accessibility statement applies to The Health Data Research Gateway (https://healthdatagateway.org/en)

Our accessibility commitment includes making sure that our website visitors can easily understand our web pages by making the content as simple as possible, allow for a reasonable amount of text resizing, navigate most of the website using just a keyboard, and perceive and navigate the website using screen recognition software such as JAWS, NVDA, and VoiceOver.

Compliance status

(b) This website is largely compliant with the Web Content Accessibility Guidelines version 2.2 AA standard, with the exceptions listed below:

Non-accessible content

The content listed below is non-accessible for the following reason(s):

(a) non-compliance with the accessibility regulations

Colour contrasts

Some of the colour contrasts within the site do not meet the colour contrast regulations. The main reason for this is HDR UK’s branding is currently under a refresh, and one of the core considerations of the new branding is accessibility. We expect therefore that this be resolved in the brand refresh in 2026.

(b) disproportionate burden

Screen reader users may struggle with the newsletter sign-up checkboxes. This is hosted outside of HDR UK and is outside our immediate control. We are aware of the issue and will look for a resolution for a future release.

Preparation of this accessibility statement

This statement was prepared on 18 November 2025 as a result of an audit of the site during the Summer of 2025. The audit was carried out by using a selection of the 10 most common pages, and 10 randomly selected pages. Using WCAG as a guide, each page was run through a checklist which included keyboard use, screen reader compatibility and content legibility.

Here is the checklist used to assess the pages:

ALT text for images
Form labels associated to inputs
