A cookie is a small text file placed on your device when you visit a website. Cookies allow a site to recognise your device between pages and across visits. Similar technologies, including local storage and pixel tags, perform comparable functions and are treated the same way in this policy.
Their use is governed by the Privacy and Electronic Communications Regulations 2003 and, where a cookie processes personal data, by the United Kingdom General Data Protection Regulation. With the exception of cookies strictly necessary for a service you have requested, we place cookies only with your consent.
Required for the site to function and for services you have requested. These include session identification, authentication of a signed-in account, security tokens preventing cross-site request forgery, and recording your cookie preferences. Consent is not required for these and they cannot be disabled through the banner, though your browser may block them at the cost of the site functioning correctly.
Remember choices you have made, such as display preferences and previously selected fields or categories, so that they persist between visits. Disabling these does not prevent use of the site but removes the convenience they provide.
Help us understand how the site is used in aggregate — which pages are visited, how visitors navigate, where difficulties arise. We use Google Analytics 4 for this purpose. These are placed only with your consent and may be withdrawn at any time.
We do not presently use advertising or cross-site tracking cookies. Should that change, this policy will be revised and consent obtained before any such cookie is placed.
| Cookie | Category and purpose |
|---|---|
| Session identifier | Strictly necessary — maintains your session across pages. Expires when the browser closes. |
| Authentication token | Strictly necessary — keeps you signed in to your account. Persists for the session duration configured for the platform. |
| Security token | Strictly necessary — protects form submissions against cross-site request forgery. Session duration. |
| Cookie preference | Strictly necessary — records the choices you made in the consent banner so you are not asked repeatedly. 12 months. |
| Display preferences | Functional — remembers interface choices. 12 months. |
| _ga | Analytics — Google Analytics, distinguishes visitors. 24 months. |
| _ga_<id> | Analytics — Google Analytics, maintains session state. 24 months. |
Cookie names and durations may change as the platform develops. This table is reviewed when such changes are made.
When you first visit, a banner allows you to accept all cookies, reject all but those strictly necessary, or choose by category. Your choice is recorded and respected on subsequent visits until it expires or you change it.
You may change or withdraw consent at any time by clearing the cookies for this site in your browser, which causes the banner to be shown again on your next visit.
All major browsers allow cookies to be blocked, restricted to first-party only, or deleted. These controls are found under privacy or site settings and operate independently of our banner. Blocking strictly necessary cookies will prevent parts of the site, including signing in, from working.
Google provides a browser add-on that prevents Google Analytics from collecting data across all sites that use it. This operates independently of the consent given here.
Personal data associated with cookies is handled as set out in the privacy policy.
