Who we are

HouseMarketBook is responsible for the information this page describes, as its controller under UK data protection law. Write to [email protected] about anything on it.

Using the site

You can use every page without an account and without giving us your name, email address or phone number. The site sets no cookies, shows no advertising and runs nothing that follows you across sites.

We count visits in two ways, neither of which uses cookies or follows you from site to site. Cloudflare Web Analytics tells us which pages are read and roughly where from, not who read them.

The other, Umami, runs on our own server at stats.housemarketbook.com, so what it records stays with us. For each page you open it records the page's address, leaving out anything typed into a search or the check tool (it keeps only the tags a link may carry to say which post it came from, such as those in our own social media posts), with the site that sent you, your browser, operating system, type of device, screen size, language and country. To tell one visit from another it makes a one-way code from your IP address and browser details, which changes every month. It does not store your IP address, it counts nothing if your browser sends a Do Not Track signal, and we delete its records after 25 months.

Searches and prices typed into the check tool are worked out as you ask and are not kept with anything that could identify you.

Who handles the traffic

Cloudflare carries every request to the site, protects it from attacks and caches pages, so it sees your IP address and browser details as any network provider would. The site runs on a server hosted by Hostinger in the United Kingdom, and our backups are kept in Cloudflare's storage. Each acts on our instructions under a data processing agreement.

The heat map's background streets come from OpenFreeMap, so your browser asks its servers for them when you open the map.

When you email us

We keep your message and our reply so that we can deal with it and refer back to it, for up to two years, and then delete them. We use them for nothing else and never add you to a mailing list.

The property records we publish

Every sale comes from HM Land Registry's Price Paid Data and every floor area from the public register of Energy Performance Certificates. Both are published openly by the government under the Open Government Licence. Neither holds the names of buyers, sellers or occupiers, and we add none.

An address with its sold prices can still relate to the people who live there. We publish it because sold prices are public by law and help people judge what homes are worth, which is a legitimate interest under UK data protection law. We never use the records to contact or market to anyone living at an address.

If you live at an address on the site and object to its page, write to us and say why. We will look at your circumstances, tell you what we decided and why within one month, and take a page down where your interests outweigh the reasons for publishing it. A wrong record is a separate matter: see corrections.

Your rights

You can ask us for a copy of what we hold about you, and ask us to correct it, delete it or stop using it. We answer within one month. If you are unhappy with how we handle your information you can complain to the Information Commissioner's Office.
