The midata initiative - download your current account transactions
midata is a government-promoted initiative that Nationwide is supporting. It allows you to download your current account transactions in a standard midata file format, which has been designed by the main providers of current accounts in the UK. The intention of the midata initiative is to help you compare different current accounts.
If you wish to, you can send your midata file to an organisation (known as a 'comparison provider') that offers midata comparison services. They will analyse your file and, based on the pattern of your transactions, may make suggestions about how to manage your account in the future, including switching to another current account provider.
Often, these comparison providers will be price comparison websites – which you may have used to compare other products, such as insurance – or they may be consumer finance information websites. Check the website of your preferred provider to see if they offer a midata comparison service.
Before you download your transaction data and send it to a comparison provider, there are some important things you should know about the midata service. Please read these notes and the FAQs.
A comparison provider will base their suggestions on assumptions about how you’ll use your current account in the future. These assumptions are based on your past transactions, but it is not an exact science. So, before you consider suggestions to move your current account to a new provider, you should look at all the features and benefits you currently have with your Nationwide current account.
Comparison providers may display their results by ranking current account providers in the order of the financial benefit you could earn if you switched account. However any non-financial benefits you currently enjoy – such as good customer service, or loyalty rewards on your Nationwide current account – will not be reflected in this ranking. This includes our Simply Rewards and Flexclusive offers.
Benefits may also include one-off switching incentives from the current account provider, such as a cash sum, but you should think carefully about whether the account is right for you in the longer term.
The midata service is covered by a Code of Practice, which applies both to the participating current account providers and comparison providers who have chosen to follow the Code. In order to give you confidence in how we will operate the midata service, Nationwide is committed to following this Code. You can read the copy of the Code of practice (along with a shorter version designed especially for consumers).
To use the midata download service, you must first be registered to use the Nationwide Internet Bank (details of how to register here). The service is only available once you are logged into our Internet Bank (see 'How to download your file' for instructions on downloading your transactions).
Our midata service will automatically download all your current account transactions for a 12-month period (the most recent transaction will be dated 31 days prior to the date of your download). If you don’t have a full 12 months’ worth of transactions then midata will download the transactions you do have in your current account, with the most recent dated 31 days prior to the date of your download (see FAQs for more detail).
To protect your personal information, some details within certain transactions in your midata file will be blanked out (full details are shown on www.pcamidata.co.uk). This has been agreed between all followers of the Code to ensure the protection of key sensitive data. This will not affect the results you may receive from comparison providers, as they will still be able to make informed comparisons.
Once you have downloaded your midata file, please review its contents to check that you are happy with the data you’ll be sharing before sending it to your chosen comparison provider. For your own protection, and to help ensure accurate results, you should not change the content of the downloaded file in any way before passing it on. If your midata file contains information that you do not wish to share, please do not pass on your file (see FAQs for more detail).
Any holder of a Nationwide joint account will be able to download their transactions into a midata file. You may want to discuss this with the other account holder before sharing your information with a comparison provider, as your midata file will contain personal transaction information for all account holders.
Who you select to analyse your midata file to is entirely your own choice, and sending your file to any comparison provider is done at your own risk. Nationwide cannot advise you which provider to use, nor can we say how they will process your personal information. So, for your own protection, it is very important that you perform some checks before you send your midata file to anyone.
Your transaction data is very valuable to third parties as it contains a wealth of information about you and your lifestyle. So please check your chosen comparison provider’s conditions and policies on their website for exactly how they will use your information – especially if they will be using it for more than comparing your current account with all those available on the market. Please also see the section below, 'Some important things to consider before you send your file'.
The midata file is downloaded from the Internet Bank.
For Windows and Apple Mac computers:
For mobile devices:
Please follow the instructions above using your mobile device's web browser. The service is not currently offered in the mobile banking app, so please log onto the Internet Banking service.
If you are using an Apple iPhone or iPad, please note that you can only view your midata file – it cannot be downloaded onto your device.
If you are using an Android device, you can both view and download your midata file.
You should be able to find the answers to these questions on the comparison provider's website.
Currently, midata transaction downloads are only available on our current accounts, although other products may be included in the future.
You will be sending all your current account transaction data for a 12-month period, minus the last 31 days from the date of download. This is done because some current account providers use recent transaction data to validate their customers when they contact them. The removal of the data for that 31-day period will not affect the results you get from a comparison provider.
If you do not have 13 months' worth of transactions in your account (from which 12 months' data can be extracted) then midata will download the transactions you do have, again excluding the most recent 31 days. However, a comparison provider will make assumptions based on the data you have to make up a picture of 12 months' worth of data, so the result you get from them may be less accurate and should be considered carefully.
For your own protection, you should send only the midata downloaded file to a comparison provider. This is because only the midata file format blanks out certain personal information.
You should not send a file in any other format, even though it may be possible to download other formats (such as .CSV or .OFX) from our Internet Bank, as your personal data will not be protected, and the file may be rejected by the comparison provider.
We encourage you to check the contents of your midata file before you send it, but if you are not happy to share the data it contains, do not send it on. You should not edit or change your file, as that could affect the results you obtain, and might cause the file to be rejected.
To get the best results, send a recently downloaded file to the comparison provider so the results are up to date.
Please follow the instructions given by your chosen comparison provider on their website on how to send them your midata file.
It is your responsibility to send your file securely using your chosen comparison provider's sending/uploading instructions. Please check that you are sending your file to a secure page on their website – secure pages usually display a padlock symbol, and have URLs that begin 'https'.
Please remember to send your midata file in its original downloaded format. If you change or save the midata file in some other format, the comparison provider may not be able to process your information.
Nationwide has no control over the results you will be given. The Code of Practice commits the comparison providers who have signed up to the Code to give accurate results, but these results may be affected by a number of factors, including:
All of this means that you have to consider the entire service you get from Nationwide (or your current account provider) before acting on the midata results.
