Cookie policy
Cookies are small text files stored in your browser. This site uses them for three things: remembering your consent choice, measuring how the site is used, and recording which campaign brought you here. Optional storage is denied by default. Where Google Consent Mode is configured in advanced mode, supported Google tags may send limited cookieless pings before consent, without reading or writing advertising or analytics cookies.
Consent is managed by CookiePal with Google Consent Mode v2. The choice is passed to supported tags so they adjust storage and network behaviour. Non-Google tags such as Clarity are separately gated by their consent category.

Attribution (first-party, only with consent)

These attribution cookies are first-party and are not directly accessible to third-party advertising scripts. They are attached to your enquiry only if you submit the contact form, and the associated identifiers may then be used to report the conversion to the advertising platform that produced the click.
