Cookies Policy
BritTherm Limited | Version: April 2026 | Company No. 11400625
This Cookie Policy explains what cookies are, which cookies BritTherm Limited uses on www.brittherm.co.uk, why we use them, and how you can manage your preferences. It should be read alongside our Privacy Policy.
We use CookieYes to manage cookie consent on this website. When you first visit, a cookie banner will ask for your preferences. You can update your choices at any time using the Cookie Settings button at the bottom left of every page.
1. What Are Cookies?
Cookies are small text files placed on your device (computer, tablet or phone) when you visit a website. They allow the website to remember information about your visit — such as your preferred settings or whether you have consented to cookies — making your next visit easier and the site more useful to you.
Cookies cannot run programmes or carry viruses. They are simply small data files that are stored locally on your device and sent back to our server when you revisit the site.
There are two main types:
- Session cookies — these exist only for the duration of your visit and are deleted automatically when you close your browser.
- Persistent cookies — these remain on your device for a set period, or until you delete them manually through your browser settings.
