Which cookies this website uses, and how to choose. Last updated: October 2026.
What cookies are
Cookies are small files that a website puts on your device. Some are essential for a website to work. Others help the people who run it understand how it is used.
Our approach
When you first visit, we ask whether you accept Google Analytics cookies. We set no analytics cookies, and send nothing to Google, unless you accept. Declining does not limit what you can see or do on this website.
You can change your choice at any time with the button below, or with the “Cookie settings” link at the bottom of every page.
The cookies we use
| Cookie | Set by | What it does | Lasts | Needs your consent? |
|---|---|---|---|---|
| rw_consent | This website | Remembers whether you accepted or declined analytics cookies | 6 months | No: it is essential to respect your choice |
| _ga | Google Analytics | Tells visitors apart, so we can count them and see how they use the website | 2 years | Yes |
| _ga_9V59ZCTFZL | Google Analytics | Keeps track of a visit, for our analytics | 2 years | Yes |
The Google Analytics cookies are set only after you accept. The information they collect is sent to Google, which may process it outside the UK. See our Privacy notice for more.
Technology that does not use cookies
WordPress.com Stats counts visits to the website (pages viewed, referring website and approximate location) without setting cookies in your browser. Images and fonts are delivered through WordPress.com’s network, which sees your IP address as it delivers them.
Managing cookies in your browser
You can block or delete cookies in your browser settings; how you do this depends on the browser. Blocking all cookies may mean the website cannot remember your choice. To stop Google Analytics on all websites, you can install Google’s browser add-on.
