Privacy Policy

Last updated: 7 October 2026

1. Who we are

Caldera Heat Batteries Limited ("Caldera", "we", "us") is the controller of personal data collected through this website. We are registered in England and Wales (company number 11020413) with our registered office at 7 Brunel Way, Segensworth East, Fareham, Hampshire, PO15 5TX. This policy explains what personal data we collect, why, who we share it with, and your rights under UK GDPR and the Data Protection Act 2018.

2. Who to contact

For any privacy question or request, contact Bianca Sassow at sales@caldera.co.uk or on +44 (0)345 034 8644.

3. What we collect and why

• Information you give us. If you contact us through the website, we receive the details you give us, such as your name, email address and company, and the content of your message. If you subscribe to our newsletter, we receive your email address and any details you provide. Our contact and newsletter forms are provided by Jotform.
• Website usage data. We use Plausible Analytics to understand how the site is used. Plausible does not use cookies and does not store your IP address. It creates a daily anonymous identifier from your IP address and browser details, which is discarded and not used to track you across days or other sites. Plausible is hosted in the EU and reports only aggregated statistics to us.
• Business-level visitor identification. We use Lead Forensics, a third-party service, to identify the organisation visiting our site. It processes your IP address and visit details and matches the IP address against business information to tell us which organisation a visit came from. Lead Forensics acts as our processor. We use this to understand which types of organisations are interested in industrial heat storage.
• Technical data. Our website host, Webflow, and our content delivery providers process technical data such as your IP address, browser type and the pages requested, in order to deliver the site and keep it secure.
• Embedded and third-party content. Our pages may embed YouTube videos and load fonts from Google Fonts. When a page loads this content, the provider receives your IP address and may set cookies or similar technologies. See section 5.

We do not make decisions about you using automated processing or profiling that has a legal or similarly significant effect on you.

4. Our legal bases

• To respond to enquiries and take steps you ask for before entering a contract: legitimate interests, and where relevant, steps at your request before a contract.
• To send our newsletter: your consent. You can withdraw it at any time using the unsubscribe link in any email or by contacting us.
• To understand website usage, keep the site secure, and identify organisations visiting the site for business development: legitimate interests. Our interest is in understanding and developing our business and keeping our systems secure. We have considered the impact on you and believe it is limited, as the identification is at business level. You can object at any time (see section 7).

5. Cookies and similar technologies

We do not use cookies for advertising or tracking across sites. Plausible Analytics does not use cookies. Lead Forensics has told us that its service does not set cookies on your device. Some embedded content may do so: YouTube (Google) may set cookies or read information from your device when a video loads, and Google Fonts receives your IP address when fonts load. You can control cookies through your browser settings. For details of how these providers handle data, see the Google Privacy Policy and the Jotform Privacy Policy.

6. Who we share data with

We do not sell your personal data. We share it with service providers who process it on our behalf and under our instructions, including Webflow (website hosting), Plausible (analytics), Lead Forensics (business-level visitor identification) and Jotform (forms and newsletter). YouTube and Google Fonts are provided by Google, which handles data it receives as an independent controller under its own privacy policy. We may also disclose data where required by law. Some of these providers are based in, or process data in, countries outside the UK. Where that happens, we make sure a lawful safeguard is in place, such as UK adequacy regulations or the ICO-approved standard contractual clauses.

7. Your rights

You can ask us to access, correct, erase, restrict or transfer your personal data. You can object to our processing based on legitimate interests, and you can object at any time to direct marketing. Where we rely on your consent, you can withdraw it at any time, without affecting processing done before. Contact us using the details in section 2. If you are unhappy with how we handle your data, you can complain to the Information Commissioner's Office at ico.org.uk/make-a-complaint.

8. How long we keep it

We keep personal data only for as long as we need it for the purpose it was collected, including any follow-up on an enquiry, and to meet legal, accounting or reporting obligations. Newsletter details are kept until you unsubscribe. We review the data we hold periodically and delete what we no longer need.

9. Changes to this policy

We may update this policy from time to time. The date at the top shows when it was last changed.
