What data do we hold?

Generally, we will only collect the following information from our suppliers, subcontractors, and their representatives:

  • Name;
  • Email Address;
  • Phone number;
  • Company; and
  • Job title.

You are under no statutory or contractual requirement or obligation to provide us with your personal information; however, we require at least the information above in order for us to deal with you as a supplier or subcontractor in an efficient and effective manner.

How we use your data and the lawful basis we rely on

We rely on legitimate interests to process your data for the following purposes:

  • To provide services to our clients – where a supplier is helping us to deliver professional services to our clients, we process personal data about the individuals involved in providing the services in order to administer and manage our relationship with the supplier and the relevant individuals and to provide such services to our clients;
  • To manage our relationship with our suppliers via email and on the phone;
  • To maintain the security of our and our clients’ information – we have security measures in place to detect, investigate and resolve security threats. Personal data may be processed as part of this. For example, automated scans to identify harmful emails.
  • To monitor the quality of our services and suppliers; and
  • To manage risk in relation to suppliers through our due diligence process for onboarding suppliers.

We are subject to legal, regulatory and professional obligations that mean we need to keep certain records to show we comply with those obligations and those records may contain personal data.

Website Visitors

When you visit our website, personal data is collected through the use of cookies. This information is limited to online identifiers and IP address.

We rely on legitimate interests to deploy cookies that are essential for the running of our websites. Where non-essential cookies (such as marketing or analytics cookies), are deployed, we rely on consent. You can withdraw your consent to such cookies at any time.

We may collect additional information about you if you fill in one of our website forms, including your name, email address, company, and your message. We process this data under legitimate interests in order to communicate with you about your enquiry.

Sharing personal data

We may share your personal data with other organisations in the following circumstances:

  • If the law or a public authority says we must share the personal data;
  • If we need to share personal data in order to establish, exercise or defend our legal rights (this includes providing personal data to others for the purposes of preventing fraud and reducing credit risk);
  • If Opinium or one of its subsidiaries is acquired by a third party, any personal data that you have provided will, where it is relevant to the part of the business being acquired, be transferred along with that part and the new owner or controlling party will, under the terms of this privacy notice, be permitted to use that data only for the purposes for which it was originally collected by us; and
  • Where we use third party data processors to process your personal data on our behalf.
Third party processors

We use third party processors to support us in providing our services and to help provide, run and manage our internal IT systems.  For example, providers of information technology, cloud-based software as a service providers, identity management, website hosting and management, data analysis, data back-up, security and storage services.

We also contract with freelancers and other research agencies within our group as well as external agencies to carry out research on our behalf.

We will only share personal data with others when we are legally permitted to do so. When we share data with others, we put contractual arrangements and security mechanisms in place to protect the data and to comply with our data protection, confidentiality and security standards.

Where we share your personal data with organisations located in third countries that are not covered by an adequacy decision, we rely on standard contractual clauses (SCCs), with the UK Addendum where required, as our mechanism to safeguard the transfer.

Individuals’ Rights

The right to be informed about our collection and use of personal data;

You have the right to be informed about the collection and use of your personal data. We ensure we do this with our internal data protection policies and through our various privacy notices. These are regularly reviewed and updated to ensure these are accurate and reflect our data processing activities.

Right to Access Your Personal Information

You have the right to access the personal information that we hold about you. This is sometimes termed a ‘Subject Access Request’. If we agree that we are obliged to provide personal information to you (or someone else authorised to receive it on your behalf), we will provide it to you or them free of charge and in most instances do so within one month unless we rely on an extension or exemption available to us under Data Protection Legislation, in which case we will notify you accordingly.

We would ask for proof of identity and sufficient information about your interactions with us that we can locate your personal information.

Right to Correct Your Personal Information

If any of the personal information we hold about you is inaccurate, incomplete or out of date, you may ask us to correct it.

Right to Stop or Limit Our Processing of Your Data

You have the right to object to us processing your personal information for particular purposes, to have your information deleted if we are keeping it too long or have its processing restricted in certain circumstances.

You have an absolute right to object to the processing of your personal data for direct marketing purposes. You can do so by clicking the unsubscribe button that the bottom of any marketing email we send you, or by emailing enquiries@opinium.com.

Right to Erasure

You have the right to have personal data erased. This is also known as the ‘right to be forgotten’. The right is not absolute and only applies in certain circumstances.

Right to Portability

The right to portability gives you the right to receive personal data you have provided to a controller in a structured, commonly used and machine-readable format. It also gives you the right to request that a controller transmits this data directly to another controller.

If you wish to exercise any of these rights, please send an email to enquiries@opinium.com. We typically have one calendar month to fulfil your rights request.

How long do we hold data for?

We retain the personal data processed by us for as long as is considered necessary for the purpose(s) for which it was collected. There may also be occasions which will require data to be kept for longer, however this will typically be for legal purposes.

In addition, personal data may be securely archived with restricted access and other appropriate safeguards where there is a need to continue to retain it. We will periodically review this data, to ensure that it is still relevant and necessary.


Data security is of great importance to Opinium and to protect your data we have put in place suitable physical, electronic and managerial procedures to safeguard and secure your collected data.

We take security measures to protect your information including:

  • Limiting access to our buildings to those that we believe are entitled to be there by use of passes;
  • Implementing access controls to our information technology; and
  • Implementing appropriate procedures and technical security measures (including strict encryption, anonymisation and archiving techniques) to safeguard your information across all our computer systems, website and offices.


We hope that you won’t ever need to, but if you do want to complain about our use of personal data, please send an email with the details of your complaint to dpo@opinium.com. We will look into and respond to any complaints we receive.

You also have the right to lodge a complaint with your local supervisory authority, which in the UK is the ICO. For further information on your rights and how to complain to the ICO, please refer to the ICO website https://ico.org.uk/concerns.
