What cookies are
Cookies are small text files stored on your device when you visit a website. We use them to understand which marketing campaign brought you here so we can attribute and improve our advertising. You do not need to accept cookies to browse this site or to submit the quote form.
Cookies we set
When you land on the site we set first-party cookies whose names begin with wml_. They store marketing attribution only — never your name, email or phone number — and each one expires 90 days after it is set.
| Cookie | Purpose | Expiry |
|---|---|---|
wml_utm_source, wml_utm_medium, wml_utm_campaign, wml_utm_term, wml_utm_content |
Store the UTM campaign values from the link you followed, so your enquiry is attributed to the right campaign. | 90 days |
wml_gclid, wml_fbc, wml_fbp and similar |
Store advertising click identifiers passed by ad platforms (for example Google and Meta) for the same attribution purpose. | 90 days |
wml_landing_url |
Records the first page you arrived on, so we know your entry point. | 90 days |
The same values are also stored in your browser’s local storage as a fallback, so attribution survives if you leave and return.
Tag manager and analytics cookies
A Google Tag Manager snippet is included in the site but is currently switched off. If and when we enable tagging, analytics and advertising cookies it sets (for example Google Analytics’ _ga cookies) will be added to this policy before they go live.
Managing cookies
You can delete or block cookies through your browser settings, and set most browsers to warn you before a cookie is stored. Guidance for every major browser is available at aboutcookies.org. Blocking the cookies above will not stop you using this site.
