Little Horsted – New Electricty Substations March update
Little Horsted – New Electricty Substations March update
Dear Neighbour
Little Horsted substation – start of works
I’m writing to let you know we’re starting work to build our new substation site near Little Horsted. Balfour
Beatty is the main contractor for the project, which is on Eastbourne Road at the junction with the A22. The
scheme involves building two electricity substations (one for National Grid and one for UK Power Networks),
two new electricity transmission pylons and the dismantling of an existing grid pylon.
The development will provide a new connection for our customer, UK Power Networks, and will ensure a
continued safe and secure supply of electricity to local homes and businesses.
We understand our essential work may impact the local community and we’ll work hard to minimise disruption
where we can. We will regularly monitor construction traffic, vehicle movements, noise, dust, vibration and
light.
We’ll begin groundworks soon after setting up our working area, which should take three months to complete.
The site needs to be levelled for the substation build and we estimate we’ll need to remove around 65,000
cubic metres of earth from site – this will involve around 100 lorry movements a day. Please be assured Balfour
Beatty will carefully manage this work and will follow a Traffic Management Plan which includes the use of
road sweepers and wheel washing facilities to help keep the area clean.
Our team will usually work between 7am to 7pm on weekdays (excluding bank holidays) and, to complete the
project on time, we will also work alternate weekends from 7am to 5pm on Saturdays and 8am to 3pm on
Sundays. HGV deliveries (not including muck away lorries) are limited to 8am to 12pm on weekends. If there
are any changes to these working hours, we will of course let you know.
We recognise our responsibility as a business goes beyond safely building new energy infrastructure and
we’re keen to leave a positive legacy where we build our projects. Through our Community Grant
Programme, we invest money in local causes and, any groups who are interested in applying for support,
can speak to our community relations team or visit our website for more details.
Our works should finish around December 2025. I would like to thank you for your patience and cooperation
while we carry out this essential work.
If you have any questions, or would like to know more, please contact our community relations team for free
on 0800 073 1047, they’re available Monday to Friday, 7am to 7pm and weekends, 7am to 1pm. An
answering service is in place outside of these times. Alternatively you can email nationalgridteam@jbp.co.uk

Little Horsted – New Electricty Substations February update
East Hoathly with Halland Parish Council
Little Horsted – New Electricity Substations
Updated February 2024
What is it?
National Grid have informed us that this project involves the development of a new electricity supply point near Little Horsted, at the junction of Eastbourne Road with the A22 (Crockstead). This is essential to allow UK Power Networks to connect to National Grid 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 Network) and two new pylons, along with the dismantling of one existing pylon.
Why is it being done?
The development will provide the 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.
What happens next?
Wealden District Council have given planning permission for the development and work will start in February 2024. The Parish Council has been supportive. Parishioners should note that :-
- a) No financial benefits accrue to the Parish from this development.
- b) The primary purpose is to improve the connection to the UKPN Lewes substation. The PC is well aware of concerns with the integrity of the electricity supply in the Parish, but enquiries to date have yielded no further information as to the nature or timetable of potential benefits related to supply security in this specific area.
Update – February 2024
Following a meeting with UKPN the following update and information has been shared with us:
The transformers are coming from the port on Shoreham (date to be confirmed). This will involve a significant traffic management plan and further details will be provided once known.
Build timetable
Between March to June 2024 Ground Works will commence to prepare the site – approx. 65,000 m3 of earth needs to be moved which will equate to 8000 lorry movements = 60-70 lorry movements a day during this phase.
Work Pattern
- Monday to Friday 7am to 7pm
- Alternate Saturdays – 7am to 5pm
- Alternate Sundays – 8am – 3pm
- No bank holidays will be worked except those agreed with Wealden Direct Council
HGV movements (not including muck away lorries) are limited to 8am to 12pm at weekends.
Potential Impacts
Security – a fence and cameras will be installed.
Footpath/Bridleway – a diversion notice will be made.
All site traffic will enter and exit the site from the entrance on the Eastbourne Road. Lorries will then have to turn left and proceed to the Halland roundabout. Onwards journeys will depend on the destination but any location north of the site will require the lorries to navigate the Halland roundabout and retrace their steps to head north back up the A22.
Ther will be regular use of road sweepers and a wheel wash facility on site.
Noise, dust, vibration and light – there will be routine and daily checks, dust suppression facilities and controls om solar lighting to reduce visual intrusion.
As construction starts here will be an average of 24 HGV trips per working day, rising to 113 at peak. Villages will be avoided and deliveries will be timed to avoid peak AM and PM times.
There will be minor lane closures or signals on Eastbourne Road for the new entrance and on the A22 (with public engagement in advance).
