Worried about a security certificate message on our website?
We have recently updated our website security certificate. This security certificate is verified by a registered authority. Because this authority has recently been set up we have been advised that some customer’s computers may not recognise the authority and therefore warns customer that the certificate may have expired or may not be valid.
If you do get this message you will have the option to select to continue using the website, although you will get a message saying that this option is not recommended. We have confirmed the certificate is valid and it is safe for you to proceed to the website.
You can update your root certificates through the normal windows update, or you can visit the Microsoft website to do it manually.
If you’re not a Microsoft user please check with your individual operating systems vendor for instructions on how to update your root certificates.
