Survey information

We are currently carrying out a range of environmental and design surveys along the Proposed Route Alignment. This means you may see some people in the area using survey equipment.

Survey activity in an area does not mean any decisions have been made about the final route or location of infrastructure. Surveys are an important part of the design process and help us understand local conditions and gather information to shape how we develop our plans.

The findings from these surveys, along with engagement feedback and ongoing technical and environmental assessments, will help shape the Project’s final design before we apply for development consent, anticipated in mid-2027.

We are carrying out the following surveys:

Information for landowners and occupiers

Our commitment

We are committed to working closely with land and property owners and occupiers, as we develop our plans for this essential electricity network upgrade.  

We will keep you updated as the Project progresses and encourage you and your professional representative to get in touch with any queries or concerns you may have. Your participation is key to building a secure, affordable and cleaner energy network for the future. 

Land referencing  

Land referencing is an important process, ensuring everyone with a legal interest in land, in and around the areas being considered for the proposed reinforcement, has an opportunity to engage in the development of the project. We have identified parties who we believe may be affected by the Project based on Land Registry Data and we have appointed land agent, Ardent, to verify the publicly available information. This is to ensure that the information is up-to-date and to confirm the current occupation of the land.  

In the Development Consent Order (DCO) process, anyone with a legal interest in land is known as a Person with an Interest in Land (PIL). If you are identified as a PIL through early land referencing, we will contact you directly. This will include issue of a 'Land Interest Questionnaire' which asks you to validate existing known information, alongside confirming all other parties with an interest in your land, that would otherwise not be available from public registers such as the Land Registry. This will allow the Project team to ensure that all those parties potentially affected by the proposals are included in correspondence and have an opportunity to help shape the proposals. 

Access for surveys  

We must develop our proposals with the right information. Over the coming months, we will carry out environmental and other surveys. These surveys will help better understand the local environment and potential effects of our project. This will also help inform our further thoughts about routeing and siting and aiding the development of detailed proposals. The findings of these surveys will be included as part of our application to the Planning Inspectorate (PINS) for development consent.  

We are requesting permission from the relevant landowners or occupiers to access private land within the route corridor to carry out some surveys. We hope that we can agree access to land voluntarily. Allowing National Grid access to land does not stop anyone with a legal interest in the land making representations about the project at any time and allowing access for surveys does not affect any rights to comment in any form.  

We always seek to agree voluntary survey access and our land agents will make every effort to do so. However, where voluntary access cannot be agreed, we will consider whether to use the legal powers available to us to enter land and undertake the necessary surveys. 

View our Construction best practice for overhead line installation guide which sets out National Grid’s approach to good practice when we carry out work to install, maintain and operate equipment on, over, in or under land and what landowners/occupiers can expect. 

Frequently asked questions for landowners

    Allowing National Grid access to land does not stop you making representations about the Project at any time and allowing us access for surveys does not affect any rights to comment in any form. 

    National Grid endeavours to reach voluntary agreement to access the land for surveys whenever possible. If agreement to access land for surveying cannot be reached voluntarily, section 172 of the Housing and Planning Act 2016 authorises National Grid as an acquiring authority to take entry onto and survey land where there is a proposal to acquire an interest in or right over land.  

    We notify local authorities where work is taking place. Although planning permission is not required for surveys, we believe it’s right to notify the local authority. 

    We recognise the potential for land damage and disturbance that may be caused by carrying out surveys and site investigations. Our licence agreements include an advance payment of compensation to landowners or occupiers of land in recognition of damage and disturbance that potentially may be caused by survey and investigation works. Further information is available in our Payments schedule for new electricity transmission assets and the Lands Right Strategy

    As we are in the initial stages of developing our proposals, we need to carry out surveys and consultation to gain a full appreciation of how these works may impact affected landowners and their activities. We employ best practice when installing new overhead lines. You can read more in our guidance document, Construction best practice for overhead line installation.  

    If you are a landowner or occupier, please direct queries about our proposals to Ardent, who are assisting National Grid as the Project’s appointed land agents. They can be contacted by phone on 0203 489 9414, or by email at [email protected].
