This is one of several posts of the topic of security of websites. Inspired by my initial post on the security of UK banks.
The reason for splitting this data into multiple posts is to make it more manageable. So that data on one type of institution is not mixed with data on another type of institution.
The following key is used for the secure status:
| Yes | The site is secure, loaded via https |
| Invalid | The site loads via https, but the security certificate is invalid and thus the site is insecure. |
| Partial | The site loads via https, but loads some parts of the page without https. The site is insecure. |
| No | The site is loaded via http, not via https. |
| Fixed | The site is loaded via https, but at the time of first writing it was loaded via http. |
| ?? | We could not find a website to evaluate. |
We tested 45 building societies. We found 16 building societies that did not have a secure home page (not https or did have https with an invalid security certificate). That is 36% of UK building societies have security vulnerabilities.

No, we’re not interested in having a guest post about finance related topics. These articles are about security, not finance.
