User testing

Occasionally, we test the site with users with disabilities or additional support needs.

If you would be interested in helping us test the site for accessibility, please email, providing contact details and information about your support needs and any special software, devices or settings you use to help you access the internet.

Testing can be done in person or you can do it remotely from your own home. It lasts no more than one hour.
