Privacy notice

What this notice covers

WattFirst is the trading name used by this website. This notice explains how WattFirst handles personal data for visitors to this website. It is maintained by us as the site owner and describes our current practices; it is not a certification or an independent audit.

It is written to be read rather than to be survived. Where a detail matters to you and is not covered, ask us and we will answer specifically.

What we collect

Calculator answers you enter are used in your browser to produce your result. In this version of the site they are not transmitted to us or stored on a server.

The forms on this site are currently disabled interface previews: no email address, consent choice or other detail is collected, transmitted or stored. If forms are enabled later, we would collect the email address and any details you choose to give, together with the specific consents you ticked and the time you gave them.

Sharing with partners

We have no commercial partners and share nothing with anyone at present. If sharing is introduced, your details would go to an installer, specialist or comparison partner only where you had ticked a specific consent box naming that purpose. Consent boxes are never pre-ticked and never bundled together.

We do not sell personal data, and we will not pass details to anyone you have not explicitly agreed to.

Documents you may upload in future

Document upload is not available on this site today. No file can be uploaded, nothing is read, and no document is sent anywhere.

Reading would be done by WattFirst's own secure AI reading service, which WattFirst operates and is accountable for. When the feature is switched on, one document at a time — a PDF, JPEG, PNG or WebP of up to 10 MB — would be sent to that service for the sole purpose of reading figures out of it, and you would be asked to acknowledge that before anything was sent. That acknowledgement covers reading the document only. It is not marketing consent, partner-sharing consent, affiliate consent, or permission to keep the file.

Documents of this kind often contain your name, address, account number, meter identifiers and payment details. The reading service is never asked to return any of those. Only the figures the calculator can actually use would be proposed to you, short evidence excerpts would have obvious emails, telephone numbers, postcodes, card-like and account-like numbers removed before you saw them, and nothing extracted would change your plan until you confirmed it, figure by figure. That removal is deliberate and tested, but no automated removal can be called infallible.

WattFirst would not intentionally retain the file after the reading request finished: the bytes would be held only for the length of that one request, never written to a public location, never placed in browser storage, and never included in logs or error reports. Your document is not used to train any model. You can abandon an import at any point before confirming, and nothing is applied. Reading is carried out by a model provider working under WattFirst's managed AI service, and processing may take place outside the UK.

To keep this private beta from being abused, WattFirst counts how many documents have been read. Those counts are kept against a random identifier stored in your browser, not against your name, email address or IP address, and they hold numbers only — never a document, a filename, its contents or any figure found in it. The counts expire on their own.

Deletion would be available on request, and any longer retention would happen only if you specifically asked for it. This wording will be revised, and the reading service confirmed as active rather than planned, before the feature is switched on.

Retention

Enquiry records are kept only as long as needed to handle the enquiry and to evidence the consent you gave, then deleted.

You can ask us to delete your details at any time and we will confirm when it is done.

Your rights

Under UK GDPR you can request access to your data, correction, deletion, restriction of processing, and portability, and you can withdraw consent at any time without affecting anything done before you withdrew it.

You also have the right to complain to the Information Commissioner's Office. We would appreciate the chance to put it right first.
