Information for landowners

When developing proposals for network upgrades, we need to understand who has a legal interest in the land in and around the areas being considered as part of the projects.

In the 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, we will contact you directly.

Whilst much of the information we need to confirm a legal interest on is available on public registers, we have appointed land suppliers Ardent to contact individual landowners to verify the publicly available information and ensure NGET has have made best efforts to identify any potentially impacted landowners. Ardent operates across multiple sectors, providing land and consenting advice to support the promotion and delivery of major projects in the UK and Ireland.

More information regarding National Grid’s land rights and payment schedules, can be found here.

Ardent will also assist with contacting landowners and occupiers to arrange access for non-intrusive and intrusive surveys which we plan to carry out whilst we develop the proposals and prepare the application for a development consent order.

More detailed information for landowners, along with relevant contact information can be found on the landowner page of our project website.

If you are a landowner and believe your property may be affected by our proposals, and want to talk to our lands team, please email [email protected] or call 0203 302 0545 or write to: EGL 3 and EGL 4, Ardent, 36 Park Row, Leeds, LS1 5JL.

Surveys

To understand more about the local environment, and to inform the environmental impact assessment, we need to carry out surveys. These will be on land within the corridor, on some adjoining land, and areas that may be identified through consultation feedback as potentially sensitive.

These surveys are to assess the landscape, ecology and cultural heritage aspects of the area, to inform further detailed environmental assessments. All survey information gathered has been published either as part of our Preliminary environmental information report or will support our application for a development consent order.
 

Ongoing surveys

Below is a list of our ongoing and upcoming surveys. If for any reason a survey cannot take place on the scheduled date, such as poor weather conditions, we will endeavour to reschedule the survey in a timely manner.

Access to land plots are agreed before any surveys may take place. If you are a landowner and have questions about the surveys on your land, please email [email protected] or call 0203 302 0545 or write to: EGL 3 and EGL 4, Ardent, 36 Park Row, Leeds, LS1 5JL.

A pair of surveyors will conduct walked transects or stationary vantage point surveys along the coastline to spatial distribution and activity information of waders and wildfowl on the intertidal shorelines and sea surface. Information will be collected on OS maps or digital devices. 

June 2025 onwards  

Bat Roost – preliminary aerial tree-climbed inspection  

Lincolnshire – East Lindsey, Boston, South Holland 

Norfolk – King's Lynn and West Norfolk

Onwards 

Bat activity surveys – static detector deployment /collection 

Lincolnshire – East Lindsey, Boston, South Holland 

Norfolk – King's Lynn and West Norfolk 

Cambridgeshire - Fenland 

A pair of surveyors will place static bat detectors in suitable habitat. This bat detector will be left in place for 1-2 weeks and then collected so the data can be analysed.  

March 2025 onwards 

Geophysical Survey 

Lincolnshire – East Lindsey, Boston, South Holland 

 

Non-intrusive surveys to detect and map contrasts between buried archaeological remains and the surrounding soil. The geophysical survey will be carried out using a handheld cart or All-Terrian Vehicle (ATV) and will require the use of a standard gradiometer, which will identify buried anomalies of potential archaeological origin at specified locations. 

April to October 2025 

Aquatic receptors (macrophyte and fish surveys) 

Lincolnshire – East Lindsey, Boston, South Holland 

Norfolk – King's Lynn and West Norfolk 

A non-intrusive walkover survey will be undertaken by a pair of experienced aquatic ecologists walking the full length of a watercourse (or suitable ditch) mapping and assessing the habitat for valuable aquatic features. The aquatic ecology walkover survey will determine whether there is a need for further targeted aquatic surveys (macroinvertebrate, fish and macrophytes). Macrophyte surveys may be undertaken within the watercourse (surveyors using waders) or from the bankside, with vegetation collected, analysed and returned in the field. Fish surveys may be also undertaken within the watercourse or via a boat (depending on the size of the watercourse). The fish survey uses electrofishing equipment, operated by certified surveyors and under an Environment Agency permit. (Electrofishing will be conducted subject to permit approval). 

 

June 2025 onwards 

Drainage Survey 

Lincolnshire – East Lindsey, Boston, South Holland 

Norfolk – King's Lynn and West Norfolk
