Cookie policy
This policy explains the cookies and similar technologies used on this website, what they do and how long they last. For how we use the information more generally, see our privacy policy.
What cookies are
Cookies are small text files stored by your browser. We also use your browser’s local storage in the same way. Together they let the site remember information — here, mainly how you reached us so we can measure our advertising.
Cookies we set
Strictly necessary and marketing-attribution
When you land on the site we set first-party wml_* cookies (and matching local-storage entries) that record marketing-attribution data: the campaign source and referring values (UTM parameters), advertising click identifiers (such as Google and Meta click IDs), and the landing page you first arrived on. These are used to attribute your enquiry to the right campaign. They are first-party only and expire after 90 days.
| Cookie | Purpose | Expiry |
|---|---|---|
wml_utm_source, wml_utm_medium, wml_utm_campaign, wml_utm_term, wml_utm_content | Store the campaign source and referring values that brought you to the site | 90 days |
wml_gclid, wml_fbc, wml_fbp and other click identifiers | Store advertising click IDs so an enquiry can be attributed to the ad that led to it | 90 days |
wml_landing_url | Records the first page you arrived on | 90 days |
Analytics & tag-manager cookies (only once enabled)
We include a Google Tag Manager snippet that is switched off by default. If and when we enable it, it may set additional analytics or advertising cookies (for example Google Analytics _ga cookies, or advertising cookies from tags we choose to load). If any such cookies read the _ga or Meta _fbp/_fbc cookies, they are used to derive analytics and advertising identifiers. This section will be updated with the specific cookies at that time, and any non-essential cookies will be set in line with your choices.
Managing cookies
You can delete or block cookies through your browser settings, and clear your local storage the same way. Blocking the wml_* cookies will not stop the site working — it only means we may not be able to attribute your visit to a campaign. Your browser’s own help pages explain how to view, delete and block cookies for that browser.
We may update this policy from time to time; the current version always appears on this page.
