Cookie Policy
Last updated: 19 October 2026
This cookie policy explains how Optimum Heat LTD ("we", "us") uses cookies and similar technologies on optimumheat.co.uk, what they do, and how you can choose which ones we use.
Your choices
When you first visit, we ask which optional cookies you are happy for us to use. Optional cookies are only set if you allow them, and you can change your mind at any time.
You have not made a choice on this device yet.
What are cookies?
Cookies are small text files that a website saves in your browser. They let the site remember things, such as what is in your basket or that you have already answered the cookie question. Similar technologies, like local storage and tracking pixels, work in much the same way, and this policy covers them too. Some cookies are set by us ("first-party"); others are set by other companies whose services we use ("third-party").
The cookies we use
Strictly necessary
Needed for the website to work, for example to keep your basket, keep you logged in, protect forms from spam and remember your cookie choices. These cannot be switched off. Because the website needs them to work, the law does not require your consent for these.
| Cookie | Set by | What it does | How long |
|---|---|---|---|
wdww_consent | This website | Remembers your cookie choices so we don't ask on every page. | 180 days |
wordpress_logged_in_*, wordpress_sec_*, wordpress_test_cookie, wp-settings-* | This website (WordPress) | Only set if you log in to the website (for example site staff). They keep you logged in securely. | Session to 1 year |
Functional
Remember your choices and turn on extra features such as maps and live chat. These are only used if you allow them.
We do not currently use any cookies in this group.
Analytics
Help us understand how visitors use the site, such as which pages are popular, so we can improve it. These are only used if you allow them.
| Cookie | Set by | What it does | How long |
|---|---|---|---|
_ga | Tells visits from different people apart, so we can count visitors. | 2 years | |
_ga_* | Keeps track of the current visit (session) for the statistics. | 2 years |
Marketing
Used by advertising partners such as Google, Facebook and YouTube to show you relevant adverts and measure how well they work. Videos from YouTube and Vimeo also use these. These are only used if you allow them.
We do not currently use any cookies in this group.
Cookie names and how long they last are set by the companies that provide these services, and they can change them. The list above is kept up to date automatically from the services this website uses.
Other companies we work with
Where a service above is provided by another company, that company may also use the information it collects as described in its own privacy policy:
Some of these companies may process information outside the UK and European Economic Area. Where they do, they rely on legal safeguards such as UK or EU adequacy decisions or standard contractual clauses.
Records of your choice
To show that we asked, we keep a record of each choice made in our cookie banner: a random ID (also stored in your wdww_consent cookie), the date and time, what you allowed, the version of this policy, the page you were on, and your IP address with the last part removed. We keep these records for 365 days. Your choice is remembered on your device for 180 days, after which we ask again.
Controlling cookies in your browser
As well as using the cookie settings above, you can block or delete cookies in your browser. If you block all cookies, some parts of the website may not work. Help pages for the main browsers: Chrome, Firefox, Safari, Edge.
Contact us and complaints
If you have any questions about this policy or how we use cookies, please email server@bos1.co.uk.
You also have the right to complain to a data protection regulator. In the UK this is the Information Commissioner's Office (ICO); in Ireland it is the Data Protection Commission; elsewhere in the EU it is your local data protection authority.
Changes to this policy
We update this policy when the cookies we use change. The date at the top shows when it was last updated. If we make a significant change, we will ask for your choice again.
