New Essential Infrastructure
Little Horsted
South East
Project description
At National Grid we are at the heart of Britain’s energy system, connecting people to the energy they use, safely and reliably. We keep the lights on so people can go about their daily lives. And we’re working to build a cleaner, fairer and more affordable energy system that serves everyone.
Electricity is carried from power stations, wind farms and other sources through a network of high-voltage electricity lines, owned and operated by National Grid. These electricity lines connect to hundreds of substations around the country, which then transfer electricity to local distributors, who in turn supply it at a lower voltage to local homes, schools and businesses.
This project involves the development of a new electricity supply point near Little Horsted, at the junction of Eastbourne Road with the A22. This is essential to allow UK Power Networks to connect to our network, enabling them to improve the electricity supply to the surrounding area and meet increased demand.
The new connection will involve building two new electricity substations (one for National Grid and one for UK Power Networks) and two new pylons, along with the dismantling of one existing pylon.
Timeline
We started engaging the local community in 2020 to explain our plans and how we’ll be working to minimise disruption and, in early 2021, we submitted a planning application for the project to the local authority, Wealden District Council. After careful review, the District Council approved our application, meaning final planning and construction for this vital project can go ahead.
Modifications to the substation design and the technology we’re using have led to a change in the programme. The work has been reprogrammed and will now start in 2024. We expect main construction will begin in early 2024 and the substations will be operational by late 2025.

Frequently asked questions
We are carrying out this development to provide a new connection for UK Power Networks, who need to upgrade their electricity network to meet future growth in electricity demand and to replace UK Power networks overhead lines, which are due for renewal, along an 18km route between Ringmer and Polegate.
Establishing a new grid supply point near Little Horsted, connected to UK Power Networks’ Lewes substation via new underground electricity cables, will maintain the future reliability of the network and means that UK Power Networks can remove 72 pylons between in the Ringmer area of East Sussex, including 10 in the South Downs National Park.
Under the Electricity Act, National Grid has a licence obligation to connect customers like UK Power Networks to its high voltage network in order to ensure a safe and secure network and to meet local demand.
The site was selected as it’s near National Grid’s existing 400,000volt (400kV) overhead line. It’s also close to the strategic road network.
In choosing this site, we have avoided sensitive environmental areas such as those with nature conservation, heritage or landscape designations. The nature of the underlying topography and vegetation in the wider area also means that the site is generally well screened, with scope for additional visual screening in the form of landscape planting.
The connection is required by UK Power Networks in the Little Horsted area. It is not feasible to use our nearest existing substations at Bolney or Ninfield as they are not where the connection is needed.
Our work near Little Horsted involves building two new substations (one for National Grid and one for UK Power Networks) and two pylons, along with the dismantling of one additional pylon. Our work allows UK Power Networks to later remove its existing overhead line, which is made up of 72 pylons in the Ringmer area of East Sussex, including 10 in the South Downs National Park.
We want to be a good neighbour and will do all we can to minimise disruption while carrying out our work.
Main construction will begin in early 2024 and the substations will be operational by late 2025.
Before work starts, we will brief all contractors to ensure they work responsibly and are considerate to the local community. This includes a briefing on considerate driving and minimising noise when entering and leaving site.
We will be keeping local people informed as the work progresses.
Our community relations team will keep the community informed by letter, information events and our website. There is also a dedicated free phone line and email address to contact if you have any questions or complaints about the works. See the 'further enquiries' information at the top right hand of this webpage for our contact details.
Compulsory Purchase Order
On 24 March 2022 National Grid Electricity Transmission Plc (“National Grid”) made The National Grid Electricity Transmission (Little Horsted Substation Connection) Compulsory Purchase Order (CPO) 2022 to enable it to compulsorily acquire the land and rights necessary to construct and operate a new substation at Little Horsted and to connect it to the National Electricity Transmission System (“the Project”).
The CPO followed a series of negotiations where we tried to secure voluntary agreements to ensure this vital Project can be delivered to meet electricity demand.
A number of objections were made to the CPO and an inquiry was held at the end of 2022.
On 4 May 2023 the Secretary of State for Energy Security and Net Zero confirmed the CPO without modifications. Notice of the Secretary of State’s decision can be found here.
A copy of the notice confirming the confirmation of the CPO has been served on all those with an interest in the land who were included in the CPO. It has also been published in local newspapers and erected at intervals across the land included in the CPO.

A copy of the confirmed CPO and the maps that show the land included in the CPO are available.
Further detail on the compulsory purchase process can be found in the Department for Levelling Up, Housing and Communities Guidance on Compulsory Purchase Process and The Crichel Down Rules (July 2019), which is available to view and download for free online at GOV.UK.
