Working to make banking fairer
Midata is an industry initiative that major UK banks, including Santander, have signed up to.

This service allows you to download 12 months of transaction history from your current account. Each bank will provide this information in the same format (CSV file), which you can then upload to independent comparison sites. 

These sites analyse your information and show you a comparison of current accounts based on your spending habits from the previous 12 months.

How do I use midata?
You can easily download your midata information from Online Banking. Simply log on as you normally would and follow the instructions below:
