However, the information may be collected on our behalf by Dalcour Maclaren Limited, an organisation we have contracted to help us.

3. Implementation of the Order

The Order was made under the Planning Act 2008 on 12th July 2023 by the Secretary of State for Energy Security and Net Zero and comes into force on 3rd August 2023. The Order authorises Orsted Hornsea Project Four Limited to construct, operate and maintain the Hornsea Four offshore wind farm together with associated offshore and onshore infrastructure and all associated development ("Hornsea Four"). The Order authorises Orsted Hornsea Project Four Limited to compulsorily acquire land, and interests in or rights over land, which is subject to the Order, for Hornsea Four or to facilitate Hornsea Four or for purposes incidental to it.

Orsted Hornsea Project Four Limited has sought to acquire the necessary land and rights for Hornsea Four by agreement however there are interests which may need to be compulsorily acquired in order for Hornsea Four to be delivered. As a part of the compulsory acquisition process, the law requires Orsted Hornsea Project Four Limited to request that those people and organisations with a legal or beneficial interest in land which might be subject to compulsory acquisition powers to provide us with information in order for us to establish whether they are entitled to claim compensation.

4. What information do we collect about you?

It is necessary for us to collect and use your personal information in order to comply with our legal obligations under the Order, the Planning Act 2008, the Compulsory Purchase Act 1965 and the Compulsory Purchase (Vesting Declarations) Act 1981 in relation to the exercise of compulsory acquisition powers.

7. Change of purpose

We will only use your personal information for the purposes for which we collected it, unless we reasonably consider that we need to use it for another reason and that reason is compatible with the original purpose. If we need to use your personal information for an unrelated purpose, we will notify you and we will explain the legal basis which allows us to do so.

8. Disclosure of your information

We may share your information with carefully selected third parties, including our professional advisers, but only for the purposes specified in this privacy notice.
