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.

Bat catching surveys

Lincolnshire – East Lindsey, Boston, South Holland

Norfolk – King's Lynn and West Norfolk

Daytime Visits: 

Surveyors will undertake a site walkover during daylight hours. This is to allow a review of suitable survey locations, health and safety risk and access restrictions to be noted ahead of the nighttime surveys commencing. 

Nighttime survey: 

The nighttime survey will consist of the team arriving approximately 1 hour prior to sunset (depending on walking distance to survey locations). The team will drive (if possible, walk if not) to the survey location for that evening. Within set locations within the land parcel, catching equipment in the form of either a harp trap or mist net will be deployed. During the evening the traps and nets will be checked regularly for bats, bats removed (if present) and processed taking the required measurements. Bats will be released as soon as the measurements have been completed. All measures will be taken to ensure the bats and surveyors safety. Surveyors will likely be undertaking the survey until sunrise, when equipment will be checked and packed up. If sufficient data has been gathered prior to sunrise, surveyors will be pack up and leave earlier than planned. The traps and nets will be monitored throughout the night, they will not block vehicle tracks without prior approval, and no equipment will be left within the land parcel once the surveys have ben completed. 

if a nighttime visit is cancelled due to weather conditions, another visit will be scheduled.
