To provide you with our products and services and comply with the law, we sometimes need to share your personal data with other trusted organisations.

Whenever we share your data, we require organisations to protect your personal data and to treat it in accordance with the law.

Some of the organisations we share your personal data with (such as IT service providers that support our business) will act as “Processors.” Processors are only allowed to use your personal data in line with our instructions.

We also need to share your personal data with other people and organisations who act as “Controllers.”  This means they need to decide how to lawfully use your personal data.

Examples of Controllers are Credit Reference and Fraud Prevention Agencies (see below), Individual Voluntary Agreement/Bankruptcy administrators, insurance companies, tax authorities, financial regulators, and law enforcement agencies. As Controllers, these organisations have their own privacy notices which will affect how they manage your personal data.

We may also need to share your personal data with organisations  if we sell, transfer, or merge parts of our business. If this happens, there won’t be any changes to how your personal data is used.

Fraud Prevention Agencies

Before we can open a mortgage or savings product for you, we must prove your identity and make  checks with fraud prevention agencies. We do this to prevent fraud and money laundering. We need to use your personal data to do this.

We, and Fraud Prevention Agencies, may allow law enforcement agencies e.g., the Police and HMRC, to access and use your personal data to detect, investigate and prevent crime. Fraud Prevention Agencies can hold your personal data for different periods of time. If you’re considered to be a fraud or money laundering risk, your data can be held for up to six years.

You can get the details of the Fraud Prevention Agencies we use by getting in touch.

Consequences of processing

If we, or a Fraud Prevention Agency, decide you are a fraud or money laundering risk, we may refuse to provide you with our products or services, including any accounts you may already have with us. A record of any fraud or money laundering risk is kept by the Fraud Prevention Agencies and may result in other organisations refusing to provide services, finance, or employment to you.

If you have any questions about this, please get in touch.

Credit Reference Agencies

To process a mortgage application, we carry out credit and identity checks on you with one or more Credit Reference Agencies (CRAs). If you already have a mortgage with us, we may carry out searches with CRAs to run your account. To do this, we will supply your personal data to CRAs, and they will give us additional data about you. This will include data from your credit record about your financial situation and history. CRAs will also supply us with public (including the electoral register), shared credit, and fraud prevention data.

We will use this data to:

  • Assess if you can afford to take out the mortgage.
  • Verify the accuracy of the data you have provided.
  • Prevent criminal activity, fraud, and money laundering.
  • Manage your account(s).
  • Trace and recover debts.
  • Ensure any mortgage offer provided to you is appropriate.

We will continue to exchange your personal data and account information with CRAs while you are a customer. We also inform the CRAs when you pay off your mortgage. If you borrow money and do not repay it in full and on time, CRAs will record the outstanding debt amount. CRAs may supply this information to other organisations.

When CRAs receive a search request from us, they will place a search footprint on your credit file that may be seen by other lenders.

If you are making a joint application and tell us that you have a spouse or financial partner, we will link your records together. This means you should discuss this with them and share the information in this section with them before making an application. CRAs will also link your records together. These links will remain on your and their files until you or your partner successfully requests the CRAs to break that link.
