Site design

In redesigning our website, we have tried to make it more useful, usable and accessible. To do so, we have followed standard web guidelines wherever possible to create our pages.


Whenever we provide a link to another site, the browser opens that site in a new window. This means that the ESR website will remain open in a window behind the new one, allowing you to return to it at any time.
