We are committed to providing a website accessible to the broadest possible audience, regardless of technology or ability.

We are actively working to increase the accessibility and usability of our website and, in doing so, adhere to many of the available standards and guidelines. 

This website endeavours to conform to the World Wide Web Consortium (W3C) Web Content Accessibility Guidelines (WCAG).

These guidelines explain how to make web content more accessible for people with disabilities. Conformance with these guidelines will help make the web more user-friendly for all. 

This site uses code compliant with W3C standards for HTML and CSS. The site displays correctly in current browsers, and using standards-compliant HTML/CSS code means any future browsers will also display it correctly. 

Whilst we strive to adhere to the accepted guidelines and standards for accessibility and usability, it is not always possible to do so in all website areas. 

We are continually seeking out solutions that will bring all areas of the site up to the same level of overall web accessibility. In the meantime, please don't hesitate to contact us if you experience difficulty accessing our website.


Where possible, use an up-to-date browser.

Using an up-to-date browser (the program you use to access the internet) gives you access to a much richer set of options to aid you as you navigate your way around this site. 

The standard browsers we would recommend are below, with links to install each of them:
Google Chrome Apple Safari Logo                       Mozilla FireFox
Chrome Safari (MAC only) Edge Firefox

Once installed, each will bring its own accessibility options and may allow further options via plug-ins. For more details, see the Accessibility page for each one:


Options in your browser:

Most modern browsers all share the most common accessibility tools; here is a list of useful features:

Incremental Search

Incremental search allows you to progressively search a web page for a particular word or phrase. To enable this on your browser, press and hold Ctrl/Command and then tap F. This will open a box to type your search into. As you type, the matches will be highlighted on the page.

Spatial Navigation

Hitting the tab bar will jump you to each item you can interact with on any page. Holding the SHIFT key and pressing the tab will take you to the previous item.  

Caret Navigation (Firefox only)

Instead of using a mouse to select text and move around within a webpage, you can use standard navigation keys on your keyboard: Home, End, Page Up, Page Down & the arrow keys. This feature is named after the caret or cursor that appears when you edit a document.

To turn this feature on, press the F7 key at the top of your keyboard and choose whether to enable the caret on the tab you are viewing or all your tabs.

Space bar

Pressing the space bar on a web page will move the page you are viewing down to the next visible part of the page.

Enlarge your view/Change fonts

Depending on your browser, you can override all fonts on the site to one that is easier to read or activate the browser zoom. Options can be found in your browser's settings/preferences.

Keyboard Short Cuts/Access Keys

Different browsers use different keystrokes to activate access key shortcuts


Options on our site:

Alternative Style

Please choose an option below to change the way the site looks. Once set, the site will remain in this style for up to 30 days or until you select a different option.

Black-on-white version

Reset to standard style

We endeavour to ensure the site looks correct in these different styles, but this may not always be possible because of the site's constantly changing nature and content. Please let us know if you spot anything that needs to be corrected.


Options on your computer:

Keyboard shortcuts

Apple Mac and Windows operating systems both contain keyboard shortcuts. For some, keyboard shortcuts can be easier than a touchscreen and are an essential alternative to a mouse. 

To zoom your entire computer screen

Apple Mac and Windows operating systems both contain options to enlarge your view of your screen:

Make your computer read the site aloud

This website has been built with screen readers in mind. Menus, pictures, and inputs will have the correct tags and markup to complement your chosen screen reader.

We have tested the following tools:

NV Access
WAVE Web Accessibility Evaluation Tool
Microsoft Windows Narrator
NVDA (NonVisual Desktop Access) is a free screen reader for computers running on the Windows operating system. WAVE is developed and made available as a free community service by WebAIM. Initially launched in 2001, WAVE has been used to evaluate the accessibility of millions of web pages.  Microsoft Windows Narrator is available in most versions of Microsoft Windows operating systems, reads text on the screen aloud and describes events like error messages so you can use your PC without a display.

Third-party voice recognition software is available, too.


In summary:
