Cookie policy
Last updated: 11 July 2026
This policy explains the cookies and similar technologies used on this website. Cookies are small text files stored on your device that help the site work and help us understand how visitors reach us. For how we handle your personal data more generally, see our privacy policy.
Cookies we set
When you land on this site we set first-party marketing attribution cookies. These record how you arrived — the campaign source and medium, referring and landing page, UTM parameters and advertising click identifiers (for example Google and Meta ad click ids) — so that if you enquire, we can credit the correct campaign. These values are stored in cookies named with a wml_* prefix (for example wml_utm_source, wml_gclid, wml_fbc) and in your browser’s local storage.
| Cookie | Purpose | Type | Expiry |
|---|---|---|---|
wml_* (e.g. wml_utm_source, wml_utm_campaign, wml_gclid, wml_fbc, wml_fbp) |
First-party marketing attribution — remembers the campaign, UTM values and ad click ids you arrived with so an enquiry is credited correctly. | First-party | 90 days |
These attribution cookies are strictly limited to measuring our own marketing and are not used to build advertising profiles of you on this site.
Tag manager & analytics cookies
We may, in future, enable Google Tag Manager to load analytics or advertising tags (such as Google Analytics or the Meta pixel). When that happens, those tags may set their own cookies — for example Google Analytics _ga and _ga_* cookies (typically up to 2 years) and Meta _fbp/_fbc cookies — and this policy will be updated to list them. This tagging is currently switched off.
Managing cookies
You can control or delete cookies through your browser settings, and set your browser to block them. Blocking our first-party attribution cookies will not stop the site working or stop you enquiring — it only means we may not be able to credit the campaign that referred you.
