We are becoming a separate company

In April 2019, Electricity Transmission is becoming a separate company within the National Grid Group. Find out more about what this change will mean.

Landowners, occupiers, and grantors

Our electricity network traverses urban and rural areas of land that are owned and occupied by third parties. The areas of land surrounding our equipment are constantly subject to change and development. This page provides you with an overview of the main areas of interaction, related publications, and contact details. 

Grantors (landowners and occupiers)

Most electricity transmission apparatuses (such as high voltage overhead lines, pylons, or underground cables) is on or under third-party land. Before we can install and operate electricity assets on land we do not own, we require rights from the owner or occupier of that land.  These landowners are known as grantors and we are committed to maintaining a successful working relationship with them.

How to contact us if you are a grantor

Access to land for maintenance and refurbishment

From time to time, we require access to land to inspect, maintain, and refurbish high voltage overhead lines. We have a duty to maintain the transmission system and power supplies, so we need quick and easy access to our equipment. 

Our rights of access to do maintenance and refurbishment work are contained within the wayleave agreement or permanent easement with the landowner. 

Overhead power lines are inspected on a routine basis both by foot and helicopter. We also have to climb pylons. Refurbishment of overhead lines can involve: 

  • Replacing conductors, insulators, and associated fittings; 
  • Painting pylons; and
  • Works to the pylons and their foundations. 

New technology is helping us to reduce the disruption caused by these things, but during major refurbishment safety scaffolding may need to be put up over properties, roads, and other development.

Minor refurbishments (such as repainting) are usually needed every seven years. Major works tend to happen much less frequently.

Electric and magnetic fields (EMFs)

Our EMF unit helpline manages enquiries from members of the public, including prospective homebuyers, sellers, and their professional advisers who may be concerned about nearby electrical equipment. 

The EMF unit provides relevant information to concerned individuals and will undertake field measurements as appropriate. We can also supply literature for home sellers to pass on to agents, prospective vendors, and their advisers. 

We are not aware of any UK mortgage lender that has a policy of refusing mortgages for properties near overhead lines because of EMFs.
