The council has a duty to protect public funds and may use personal information and data-matching techniques to detect and prevent fraud, and ensure public money is targeted and spent in the most appropriate and cost-effective way. Information may be shared with internal services and external bodies like the Audit Commission, Department for Work and Pensions, other local authorities, HM Revenue and Customs, and the Police. This activity is carried out under Article 9(2)(b) of the GDPR, under social protection law.

We have a duty to improve the health of the population we serve. To help with this, we use data and information from a range of sources including hospitals to understand more about the nature and causes of disease and ill-health in the area. This data would normally be anonymised and never used to make decisions on a specific individual or family. 

How long do we keep your information?

We will only hold your information for as long as is required by law and to provide you with the necessary services. This would vary depending on the service you received. Each service has a different retention, For further details, you can view our retention schedule.

Business Intelligence, profiling and automated decision making

We may analyse your personal information to improve services and for the following purposes:

  1. Undertake statutory functions efficiently and effectively
  2. Service planning by understanding your needs to provide the services that you request.
  3. Understanding what we can do for you and inform you of other relevant services and benefits
  4. Help us to build up a picture of how we are performing at delivering services to you and what services the people of Tower hamlets need.

The council is however committed to using pseudonymised or anonymised information as much as is practical, and in many cases this will be the default position.

We may use your information from the different services that you engage with to create a single view and profile of you, which will help us to better understand your specific needs and ensure we are providing the right and efficient services to you in accordance with your needs as well as ensure that we hold one accurate record of your basic personal data across all our council services; such as your name, DoB, address, email address, change in circumstances etc. 

Profiling will be carried out only when it is necessary in order to provide you with the service you have agreed to receive or where the council has a statutory obligation or where to the law allows.   However, we will notify you where we would do this.

Your information choice and rights

Where we use your personal data for other purposes other than what you have consented or where we have to fulfil a statutory obligation, or where the data protection law allows, then we will let you know so that you can make an informed choice about how your information is used.

If you do not want your information to be used for any purpose beyond providing the services you have agreed to receive, such as; sharing it with our partners or providers for service delivery planning or improvement of services or for Business Intelligence, profiling research or statistical purposes (in such instance only minimum and necessary, anonymised or pseudonymised data will be used), you can choose to opt-out of this.

Data protection legislation gives you a number of rights in relation to your personal data. The rights available to you will depend on the Lawful basis that we rely on to process your personal data. We have a legal obligation to process your personal data for the provision of this service, as such the following rights are available to you:

  1. Right to rectification
  2. Right to restrict processing (limited cases).
