Who are we?

The Hyperion Executive Search companies (Hyperion Executive Search Ltd, Hyperion Executive Search GmbH and Hyperion Executive Search Inc) provide executive search and talent solutions to clients in the cleantech sector looking to identify and engage leadership, executive and board level talent to achieve their growth objectives. 

What does this Policy cover?

This Privacy Policy explains our use of personal data processed through the website if you choose to contact us and our use of business contact details. It also explains how we use candidate personal data and the personal data of our clients.

What personal data do we collect and why do we use it?

The table below explains who we collect personal data about, what that personal data is and the purpose we process it for. 

The last column sets out the ‘lawful basis’ we rely on for processing that personal data which is a requirement of data protection rules. Essentially, companies may only process personal data if they can identify a lawful basis from a list set out in the legislation.

Individual Personal Data Source and Purpose Lawful Basis for Processing
Candidates CVs, identification documents, educational records, work history, employment record and references, correspondence and other personal data necessary as part of the recruitment or engagement process.

We rarely process special category information such as disability or health information where you have made this available to us.

We mainly collect this information directly from you during the recruitment, engagement and onboarding stages.

Sometimes we collect information from third parties such as an agent acting on your behalf such as an interim manager or from a third-party recommendation or a person giving a reference.

We do use some publicly available sources to find information about potential candidates, specifically LinkedIn, Xing and company websites.

Also see note below this table about software programs that may used to source candidates.

We may use your information to provide you with our newsletters including information about available jobs and relevant industry insights. You can unsubscribe from our newsletter at any time by clicking the ‘unsubscribe’ link at the bottom of any email newsletter.

The processing is necessary for our legitimate interests of assessing suitability for potential roles, to find potential candidates.

If you choose to give us special category data (listed in the second column), we obtain your express consent to process that.

Essential Cookies, Performance Cookies and Functionality Cookies.  We only install non-essential cookies with your consent. For more details see our Cookie Notice.

Where we have indicated in the table above that we rely on legitimate interests for processing of personal data, we carry out a ‘balancing’ test to ensure that our processing is necessary and that your fundamental rights of privacy are not outweighed by our legitimate interests, before we go ahead with such processing. We keep a record of these balancing tests. You have a right to and can find out more about the information in these balancing tests by contacting us using the details below.

Where we collect candidate information through publicly available sources as set out above, we may do this with the aid of software programs such as those used by Zoominfo, Lusha etc. These programs are given parameters on the requirements of a role and search through publicly available sources to find such candidates. These programs are designed to only output information on candidates that meet the search criteria. The parameters of these programs are restricted to only searching for candidate information from public sites where there is a reasonable expectation that such information may be collected and further processed by recruiters for the purpose of sourcing candidates for different job roles.

How long do we keep your personal data for?

We keep your information only for as long as is necessary for the relevant purpose. For example, if we have a contract with you, this will be for 6.5 years after expiry in order to assist us with any contractual claims. We use a number of criteria for determining the retention period including obligations under law, our need to defend or bring contractual claims within the statutory limitation period and consideration of the original purpose we collected it for.

Who do we share your personal data with?

  • Data may be shared in the following circumstances:
  • Where you are a candidate:
    • we share your personal data with the client who has a position to fill in order to determine with the client whether you are a good fit for an available position.  Clients are in cleantech related industry sectors globally; 
    • where your recruitment process involves a psychometric assessment, we share your information with a third-party assessment provider, e.g. Insights Practitioner.
  • With professional advisors;
  • In the event of a sale of the company or its assets;
  • With suppliers but only subject to robust contractual protections;
  • Other companies in our group: Hyperion Executive Search Ltd; Hyperion Executive Search GmbH; Hyperion Executive Search Inc; Fully Charged Recruitment Ltd; 

What happens if you do not provide us with the information we request or ask that we stop processing your information?

If you do not provide the personal data necessary, we may not be able to respond to your query or consider your application or request or match you with available role opportunities or to provide the relevant services to you.

Do we make automated decisions concerning you?

We do not carry out this type of processing activity.

Do we transfer your data outside the UK and EU?

We may sometimes transfer your personal data to countries outside the UK and European Economic Area, for example, to our group companies, or if we are either using a supplier or working with a client based elsewhere. You can find the list of European member states here . The privacy laws in countries outside the UK and European Economic Area may be different from those in your home country. 

At present, we transfer personal data to the following countries outside of the UK and European Economic Area: USA 

Where we transfer data to a country that has not been deemed to provide adequate data protection standards, we always have security measures and approved model clauses or other adequate safeguards in place to protect your personal data. Please contact us if you would like more details about our safeguards for data transfers.

What rights do you have in relation to the data we hold on you?

By law, you have a number of rights when it comes to your personal data. Further information and advice about your rights can be obtained from the data protection regulator in your country. In the UK this is the Information Commissioner.

We usually act on requests and provide information free of charge, but may charge a reasonable fee to cover our administrative costs of providing the information for:

  • baseless or excessive/repeated requests, or 
  • further copies of the same information.

Alternatively, we may be entitled to refuse to act on the request in some circumstances.

Please consider your request responsibly before submitting it. We’ll respond as soon as we can. Generally, this will be within one month from when we receive your request but, if the request is going to take longer to deal with, we’ll come back to you and let you know.
