This privacy notice tells you what to expect when you provide your personal information to Heathrow Airport Ltd (Heathrow) in connection with the Airport Expansion Consultation. Heathrow is committed to protecting your personal information. Whenever you provide personal information we are legally obliged to use it in line with all applicable laws concerning the protection of personal data, including the General Data Protection Regulation (GDPR) and the Data Protection Act 2018.

The Airport Expansion Consultation is a statutory 12 and a half-week consultation on Heathrow’s expansion plans, and will be open between 18 June 2019 and 13 September 2019. During the Airport Expansion Consultation, you will be able to submit your views on the expansion plans by post or by using our online form. (The consultation is now closed)

If you use our online form to submit your views, you will be provided with two facilities, which are to either “Protect Your Response” or “Complete Later”. If you use either of these facilities, Heathrow will collect and use your email address in order to send you a URL (a website link) that is unique to you only. We will email this link to you so that, providing you save your responses using the button, you can return to them at any time should you get disconnected or wish to complete your response over a number of days. The facility is open until the closure of the consultation. All responses must still be completed by 23:55 on September 13th 2019. In the final week of consultation, Heathrow may send a reminder so that you do not miss your opportunity to respond.
Email addresses collected for use of the “Protect Your Response” or “Complete Later” facilities are only used for the successful operation of these facilities, they will not be attached to your final submission (although you may choose to provide your email address in the course of submitting your views, as described below).

When you submit your views to Heathrow in connection with the Airport Expansion Consultation, whether through our online form or by post, we will collect the following information about you:

  • Name;

We will also collect certain information automatically when you visit our website. This will include your IP Address and Browser ID; the combination of these two pieces of information enable the identification of a specific computer or other network device on the internet.

Heathrow will use your personal information for a number of purposes, including the following:

  • To record accurately and analyse any questions you raise during the Airport Expansion Consultation or feedback you have provided in response to the Airport Expansion Consultation;
  • To report on the Airport Expansion Consultation, setting out what issues have been raised and how we have responded to that feedback;
  • To ensure the safety of our staff.

Heathrow will use the information, along with the responses provided to help enable us to develop our designs further.

We will keep personal information within Heathrow and our trusted third parties except where disclosure is required by law, for example to government bodies and law enforcement agencies. Your information will be handled and may be used by the following recipients in order to provide this service:

  • Postcode Checking Webservice: We use a third party webservice to enable the postcode and address look-up facility on the Airport Expansion Consultation website. The webservice will not retain your information;
  • Professional advisors: We engage the services of professional advisors in the UK who may receive your personal information to provide advice in connection with Heathrow’s expansion plans;

Personal details will be stored on this secure facility for no more than 30 days. Please refer to “How long will Heathrow keep my information?” for more information about data retention and removal. Your information will be processed in the UK, however email records will be stored on US based servers.

We may be required to make copies of responses to the Airport Expansion Consultation available to the Secretary of State and/or the Planning Inspectorate. We will request that personal information is not placed on the public record, however, please note the Secretary of State and/or the Planning Inspectorate may use any personal information that is disclosed to them in accordance with their own privacy policies, over which we have no control. We recommend that you do not include any information in your response to the Airport Expansion Consultation that you would not want to be viewed by these third parties, or potentially to be placed on the public record.

To demonstrate that Heathrow is engaging with and seeking the views of, the widest possible range of local residents and communities, we are inviting you to provide the information set out below, but only if you are over the age of 18 and you wish to do so.

Your responses to the equalities survey will NOT be linked to your IP or Browser ID nor will we ever attempt to identify the individuals behind these survey responses.
