National Grid ESO Privacy Policy

We are required under the Planning Act 2008 to request your views on planning proposals for large scale infrastructure development projects if they are likely to have an effect on you. For smaller projects where we are not under obligation to consult, we may still seek your views on proposed developments to help inform our decisions.

You may choose whether to respond to such requests. If you do respond we will use your name and home or business contact details – including postal address, email address, and landline or mobile number – to contact and update you on progress of the project.

We will also keep a record of your contact details and consultation feedback as required by laws governing the planning application process.

If you are a landowner and we are unable to negotiate a voluntary agreement regarding land rights for the construction, access to and maintenance of our infrastructure then we may exercise our powers under the Electricity Act 1989 in order to obtain either a ‘necessary wayleave’, or obtain land rights by compulsory acquisition.

This will involve processing of your contact details - including postal address, email address, and landline or mobile number – along with details of your land ownership or occupation.

If you hold shares in National Grid plc, we have obligations under the Companies Act 2006 to collect and use personal information to keep a register of members, provide you with share certificates or other evidence of your shareholding, and contact you regarding your rights to attend and/or vote at the Annual General Meeting. For more information about what we use and why see our Shareholder Privacy Notice.

If you are contracted by one of our suppliers and service providers to carry out work at a site where high pressure gas is stored or transmitted, we will keep records of your job title and the results of any training, qualifications, certificates, professional licences or memberships that demonstrate your competence to work on site and/or to restricted access to areas of a particular site, for example by issuing you with an access card. Competency records are kept in electronic and hard copy format and may in some cases include voice recordings of assessments. This information is used to demonstrate compliance with the Control of Major Accident Hazards (CoMAH) regulations, our obligations under Health & Safety at Work legislation, and our Operating Licences.

If you are a landowner or tenant and a project that affects your land has received planning permission then we will attempt to reach an agreement with you regarding access to construct, assess the condition of, maintain, repair, or replace our assets. In order to reach such a voluntary wayleave or easement agreement it will be necessary to process your contact details - including postal address, email address, and landline or mobile number – along with details of your land ownership or occupation.

If you are a landowner or tenant and one of our construction projects results in loss of or damage to your land – for example loss of crop yield, grazing land, or damage to drainage or access roads – you may be entitled to claim compensation from us. In order to process your claim we require details of the land you hold interest in and evidence to support your claim – for example photographs and financial statements / forecasts.

If your claim is successful, we will need to process your bank details to make compensation payments. We will also keep records of amounts paid.

In the event you have applied for a job at National Grid, we use the personal information you submit to process your application.

If you are a customer, supplier or service provider we need to process certain data items, such as your name, postal address, phone number, email address and bank account details in order to provide goods and services to you and receive payment, or receive goods or services from you and pay you for them.

If you contact us with a query or complaint about any of our activities, we will record the details of your request, and if we are unable to immediately resolve the matter we will ask you to provide contact details of your choice - such as a telephone number, email, or postal address - which we will use to contact you with updates when we have investigated the matter further.

We provide a helpline where you can contact us if you have any questions regarding the effects of Electromagnetic Fields (EMFs) and noise resulting from the operation of the electricity network. We use the preferred contact details you provide us (your email address, home or personal mobile number, or postal address) to respond to your queries and provide advice. Where you choose to provide it, we also process information about any actual or perceived physical health effects resulting from EMFs, and, if your enquiry relates to effects on children, details of the number and ages of children in your household.

We use aggregated data, based on the information you provide to us, for scientific research and statistical purpose with regard to the effects of EMFs and ways of mitigating them. We share this aggregated data with the Energy Networks Association. We do not share any personal information for this purpose.

For more information about how we use your personal data in relation to EMF queries please see our separate EMF Privacy Policy.

When you visit one of our sites you will be asked to provide your name and contact details in order to be issued a visitor access card. These cards record the dates and times you enter and leave a particular site or part of a site. If you have requested a parking space on one of our sites, we will also record your vehicle registration number.

We use CCTV cameras to monitor the interior of, entrances to, and perimeter of our sites to enable us to respond to security incidents. Footage from some cameras is monitored remotely in real time to facilitate responses to security or safety incidents. All cameras – monitored or otherwise – will store recordings of the footage, which may be reviewed at a later date and used as part of a security or safety incident investigation. If the footage captures evidence of an offence being committed, we will share this with the police.

CCTV is also used on some of our sites to monitor the opening and closing of automated or remotely operated gates or barriers to ensure you are not trapped or injured.

All of these measures are in the interest of your safety and wellbeing.

If you submit a DSAR we will search all systems and relevant hard copy data stores and retrieve the information that you request. We will hold copies of your request, along with copies of the information retrieved and disclosed to you (or, subject to the application of a valid exemption, withheld or redacted) as evidence of compliance. We may be required to share with the Information Commissioners Office (ICO) if required, for example to comply with an audit or investigation. Where we hold any special category personal information as such evidence we do so on the basis of establishing, exercising or defending legal claims.

Your voice may be recorded when making calls to some company numbers, for example helpdesks and trading desks. You will be informed at the start of the call if the call is to be recorded. We use these recordings to monitor compliance, conducting safety investigations, and for training purposes.

If an electricity construction project is being proposed in your local area, we may invite you to sign up to receive information and updates on the project. If you provide your name and email address, we will use this, with your permission, to send you project updates. You may opt-out of receiving updates at any time: you will be informed of how to do so in each email we send you.
