What we collect and why.
Last updated 11 August 2026.
Quote and contact requests
If you submit a form, we store the details you provide so we can review and respond to the request. We do not share the request with an installer unless you tick the separate installer-sharing box.
Calculator use
The calculator runs in your browser. Its assumptions may be copied into a form only when you choose to submit that form.
Retention and rights
We retain enquiry information only as long as needed to handle the request, maintain records and meet legal obligations. You may request access, correction or deletion by replying to our contact email. We will add full controller contact details before commercial promotion.
Analytics
Non-essential analytics and advertising storage are disabled unless a compliant consent mechanism is introduced.
