Privacy notice

The Property Plan, run by Underground Knowledge Limited. Last updated 15 November 2026.

Who holds your details

Underground Knowledge Limited, the company behind The Property Plan, is responsible for your details. Contact us about privacy at any time: hello@thepropertyplan.uk.

What we collect and why

When you ask for the free guides we collect your first name and email address so we can give you access to them. If you also tick the box for the monthly property tips, the same details are used to send that email. Each is separate: asking for the guides never signs you up to marketing.

The law calls the reason for each use a lawful basis. Submitting the form is your consent for us to use your details to deliver the guides you asked for. The monthly tips are separate: we send them only if you tick the tips box, and that tick is your consent for marketing. We also keep guide requests for a short time afterwards in case something goes wrong with your access; that is our legitimate interest in making sure the guides actually reach people who ask for them.

Who handles your details

Two service providers handle your details for us: Zoho Campaigns, our email system, which holds the list in Zoho's UK data centre, and Cloudflare, which hosts this website. They process your details only on our instructions, and where any processing happens outside the UK it is under the contract terms UK data law requires. We never sell your details and never share them for other companies' marketing.

How long we keep them

If you only asked for the guides, we delete your details at the next weekly review after 90 days from your request. Deleting in our email system queues permanent removal, which the system then completes within 15 days. That is long enough to sort out any problem getting the guides to you, and no longer. If you get the monthly tips, we keep your details until you unsubscribe. When you unsubscribe we keep only the minimum record needed to make sure you stay unsubscribed.

Your choices and rights

Every tips email carries an unsubscribe link, so withdrawing consent is as easy as giving it. You can also ask us at any time to see, correct or delete the details we hold about you, or to object to how we use them: hello@thepropertyplan.uk. If you are unhappy with how we handle your details you can complain to the Information Commissioner's Office at ico.org.uk.
