Cookies and browser storage

This site uses a few first-party cookies and browser storage. Your banner choice decides what runs beyond what the site needs to work.

vp_vid

First-party visitor identifier, kept up to 395 days. It lets us count visits and link an enquiry to the pages that led to it.

vp_sid

Session identifier. It ends after 30 minutes without activity.

vp_chat_session (browser storage)

Keeps your chat with us open when you come back to the site.

vp_test

Marks our own staff test traffic so it is not counted as a visitor.

Advertising tags

Where advertising measurement is switched on and your banner choice allows it, Google Tag Manager loads Google and Meta tags, which set their own cookies.
