How you should be able to use this website

We want as many people as possible to be able to use this website. You should be able to:

  • change colours, contrast levels and fonts using browser or device settings
  • zoom in up to 400% without the text spilling off the screen
  • navigate most of the website using just a keyboard
  • navigate most of the website using speech recognition software
  • listen to most of the website using a screen reader (including the most recent versions of JAWS, NVDA and VoiceOver)

We’ve also made the website text as simple as possible to understand.

AbilityNet has advice on making your device easier to use if you have a disability.

How accessible this website is

We know some parts of this website are not fully accessible, for exmaple:

Enforcement procedure

The Equality and Human Rights Commission (EHRC) is responsible for enforcing the Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018 (the ‘accessibility regulations’). If you’re not happy with how we respond to your complaint, contact the Equality Advisory and Support Service (EASS).

Technical information about this website’s accessibility

Government Communications Headquarters 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 2.2 AA standard, due to the non-compliances and exemptions listed below:

  1. Some of the images on the site do not have appropriate text alternatives. In some cases, decorative images have descriptive text alternatives where these should be empty, and in other cases images that aren’t decorative do not have descriptive text alternatives. This fails WCAG 2.2 success criterion 1.1.1 (Non-text content)
  2. Some tables do not have table row or column headers. This means assistive technologies will not read the tables correctly. This fails WCAG 2.2 success criterion 1.3.1 (Info and Relationships).
  3. Some PDFs do not use bookmarks to aid navigation. This fails WCAG 2.2 succession criterion 2.4.5 (Multiple Ways).
  4. Existing pre-recorded audio and video on this site may not include captions. We do not plan to add captions to these recordings, because these are exempt from meeting the accessibility regulations.

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

The accessibility regulations do not require us to fix PDFs or other documents published before 23 September 2018 if they’re not essential to providing our services.
Existing pre-recorded audio and video on this site may not include captions, and we do not plan to add captions to them. This is because these are also exempt from meeting the accessibility regulations.

What we’re doing to improve accessibility

We are working alongside agencies to fix content which fails to meet the Web Content Accessibility Guidelines version 2.2 AA standard.
