Privacy Policy
This policy explains what personal data we collect through this website, why we collect it, and the choices you have. It applies to secondaryglazingcost.com.
Who we are
Secondary Glazing Cost Guide is an independent information resource for homeowners in London and the Home Counties, publishing secondary glazing cost guidance and connecting enquiries with specialist installers.
What we collect
- Enquiry details you submit through our contact and estimate forms: name, email address, phone number, property location and a description of your project.
- Calculator inputs such as window counts, sizes and glass choices. These are processed in your browser to produce an estimate and are only sent to us if you submit a form.
- Usage data collected by Google Analytics 4: pages viewed, approximate location, device and browser type, and how you reached the site.
Why we use it
We use enquiry details to respond to you, prepare an estimate and — where you have asked us to — arrange a survey with a specialist installer. Usage data helps us understand which guidance is useful and improve the site. We do not sell your personal data, and we do not use it for automated decision-making.
Legal basis
Under UK GDPR we rely on your consent when you submit a form or accept analytics cookies, and on our legitimate interest in responding to enquiries and maintaining a secure, useful website.
Who processes your data
- Formspree — delivers form submissions to our inbox.
- Google Analytics 4 — anonymised and aggregated website usage measurement.
- Netlify — website hosting and server logs.
Each processor handles data under its own agreement with us and may store data outside the UK under appropriate safeguards.
How long we keep it
Enquiry records are kept for up to 24 months so we can follow up on quotes and honour warranty questions, then deleted. Analytics data is retained for 14 months in line with Google Analytics defaults.
Cookies
We use essential cookies to make the site work and Google Analytics cookies to measure usage. You can block or delete cookies in your browser settings, and enabling your browser's "Do Not Track" or privacy mode will limit analytics collection.
Your rights
You have the right to access, correct, delete or restrict the personal data we hold about you, to object to processing, and to request a copy of it. You can also withdraw consent at any time. To exercise any of these rights, contact us using the form on this site. If you are unhappy with our response you can complain to the Information Commissioner's Office.
Changes to this policy
We may update this policy as our services or the law change. Material changes will be reflected on this page.
