TheSolarPlug (thesolarplug.com) is a free calculator that estimates solar and battery savings for UK homes and shows a ranked comparison of plug-in solar packages. It runs entirely in your browser — there are no user accounts, logins or server-side databases behind the calculator itself.
We collect as little as possible:
To make the calculator work, your browser loads a few external resources. Each of these may log standard connection data (like your IP address) under their own privacy policies:
We don't currently run any analytics or advertising trackers on this site. If that changes (for example, adding Google Analytics), this policy will be updated to name the tool and explain what it collects.
The calculator itself doesn't set cookies. If we add analytics or advertising in future, we'll update this section and, where required, ask for your consent first via a cookie banner.
Some links on TheSolarPlug (including "Get 10% off" buttons) are referral links. If you buy through one, the retailer may pay us a referral reward and may set their own tracking cookie once you leave our site — that's covered by their privacy policy, not ours. See our Terms of Use for more on this relationship.
Because we don't collect or store personal data on our own servers, there's generally nothing of yours for us to delete, correct or export. If you believe that's changed, or you have any question about this policy, contact us using the details below.
We may update this policy as the site changes. The "last updated" date at the top will always reflect the latest version.
