How we protectyou online

Online Security

We take the security of our online services very seriously. Here's an overview of the security measures we have taken. We suggest you also read How you can protect yourself

Keeping your personal information secure

Your information is kept by Chelsea Building Society for as long as necessary to operate your accounts. All forms and online account pages, i.e. those pages that show or collect your information, use High Grade 256-bit SSL encryption which is the strongest level of encryption currently available to the public.

Encryption makes your information unreadable to anyone who might intercept it.

Secure Socket Layer (SSL)

A "Secure Sockets Layer" is a commonly used method of managing the security of information transmitted across the Internet and is used by us whenever we ask you to enter any personal information, including passwords. You can tell that SSL is in use when a small padlock icon appears on your browser status bar.

The latest browsers support High Grade 256-bit SSL encryption.

Confirming online requests

When you request a transaction or other change online, we may occasionally contact you by telephone to check the details. It is therefore important that you keep us informed if you change your number, and wherever possible provide more than one number on which you can be contacted.

As online requests are generally confirmed by email, make sure we have your correct email address and check your inbox regularly for new messages.


You should note that ordinary email is not secure. Please do not send us any confidential information via email. Similarly, we will not use email to send confidential information about your accounts to you unless you specifically request, and agree to, this.

Using passwords

In addition to the use of SSL, you will need to provide security passwords to access the secure parts of the site. You choose your own passwords when you set up your online account.

Remember that your password is the key to your account. Make sure that you look after your password and keep it secret.

Monitoring our security arrangements

Our website is constantly monitored for security problems. We also regularly review our security arrangements in line with latest developments in the technology available.
