This Privacy Policy is designed to tell you about our practices regarding collection, use, and disclosure of information that you may provide via Tunnelworks, this Website. Please be sure to read this entire Privacy Policy before using or submitting information to this Website.

Your consent
By using this Website, you agree with the terms of this Privacy Policy. Whenever you submit information via this Website, you consent to the collection, use, and disclosure of that information in accordance with this Privacy Policy.

Data protection
Bazalgette Tunnel Limited operates in accordance with the Data Protection Act 1998 and the policy statement as set out below. If at any time you no longer wish to receive information from us please let us know in writing or by email.

Bazalgette Tunnel Limited and its agents will process personal information that you may provide for the purpose of consultation, statistical analysis, profiling and administration of the Thames Tideway Tunnel project. The data may be used in order to keep you informed about the progress of the Thames Tideway Tunnel proposals, for maintaining the book of reference of those with relevant interests in the land affected by the proposals (and keeping it up to date) and for the purposes of serving any notices which may require to be served in connection with the proposals.

Active information collection
Like many websites, this Website may actively collect information from visitors by permitting you to communicate directly with us via e-mail and feedback forms. Some of the information that you submit may be personally identifiable information (that is, information that can be uniquely identified with you, such as your full name, address, e-mail address, phone number, and so on).

Some areas of this Website may require you to submit information in order for you to benefit from the specified features (such as newsletter subscriptions) or to participate in a particular activity (such as online polls). You will be informed at each information collection point what information is required and what information is optional.

Passive information collection
As you navigate through a website, certain information can be passively collected (that is, gathered without your actively providing the information) using various technologies and means, such as Internet Protocol addresses, cookies, Internet tags, and navigational data collection.

The Website may use Internet Protocol (IP) addresses. An IP Address is a number assigned to your computer by your Internet service provider so you can access the Internet and is generally considered to be non-personally identifiable information, because in most cases an IP address is dynamic (changing each time you connect to the Internet), rather than static (unique to a particular user's computer). We use your IP address to diagnose problems with our server, report aggregate information, determine the fastest route for your computer to use in connecting to our site, and administer and improve the site.

A "cookie" is a bit of information that a website sends to your web browser that helps the site remember information about you and your preferences. More information about cookies, including how to block and/or delete them, via a range of common browsers, can be found at
