We only share your personal data with third parties where it is necessary for us to do so in order to fulfil our obligations to you under our contract, or where we are required to do so in order to comply with a regulatory or legal provision. We will never sell your personal data for direct marketing.

The circumstances in which we may share your personal data with third parties includes:

  • where we are required to share your personal data, for example with HMRC;
  • where we use a provider of services, for example in relation to our computer systems or programmes which we use for our business operations including our employee’s pension provider and Bright Flair Limited which we use for software services;
  • where we use consultants such as Derwent Hydro Developments Limited for services;
  • using security companies to monitor the CCTV we use at some of our sites; and
  • where we share your personal data with our professional advisers such as insurers and lawyers.


We use CCTV monitoring for the purposes of security and of monitoring our operational assets ans the areas in which we are working (for example our equipment and water flow). On site you will be notified of CCTV operation via appropriate signage. The CCTV is monitored and administered by third parties as well as the Company. Further information about the administration of CCTV monitoring can be obtained by contacting us. CCTV images are recorded.

The personal data that we collect from you may be transferred to, or stored at, a destination outside the European Economic Area (EEA). For example, we use Google Drive which is provided by Google LLC, and Dropbox, which is provided by Dropbox International Unlimited Company, both of which may transfer personal data outside of the EEA.

Where we need to transfer your personal data outside the EEA, we will take all steps reasonably necessary to ensure that any such transfer is made securely and that there is adequate protection in place in order to protect your personal data.

Please contact us if you wish to find out more; you are welcome to ask us for a copy of the relevant safeguards implemented in relation to any transfers outside of the EEA.
