SSEN Distribution has begun a programme of works to strengthen the electricity distribution network serving more than 140 thousand customers in Swindon and the surrounding area, the network operator announced on 13 January 2026. The company puts the investment at around £100m and says the works will run between now and the turn of the decade, delivered with its partner OCU Group.
"We're making an investment of around £100m to future-proof and strengthen the electricity distribution network for more than 140 thousand customers in Swindon and the surrounding area."
SSEN lists three areas the programme is intended to support: economic growth, decarbonisation and network resilience. On decarbonisation, the company says the investment will help enable the connection of more low-carbon technologies such as electric vehicle chargers and heat pumps, and support new community and smaller-scale renewable generation including solar and battery storage. It also states that a separate SSEN Distribution pilot project, which can inform residents if the electricity supply into their property needs an upgrade to support low-carbon technology, began last autumn. No further detail on that pilot, including how households are selected or what an upgrade would involve, has been reported.
On disruption, SSEN says it is working with Wiltshire Council so that works on roadways and footpaths are planned to minimise impact. It says ducting for a new underground cable route between Stratton and Faringdon will be installed before the council starts its own work on a new footpath. Much of the work will take place within existing substation sites, which SSEN says will have little impact on neighbouring communities, while modernisation and cable replacement in other areas will be more visible. The company says it will contact homes and businesses in good time when improvements are made in a specific area.
Carl Pates, SSEN's Swindon Project Director, said the network needs the capacity and resilience to support customers moving away from fossil fuels, adding that the project "will be carried out considerately, so the works themselves will have as little impact as possible on communities"1. Councillor Helen Belcher, Cabinet Member for Economy and Regeneration, described the investment as good news for the area and said strengthening electricity infrastructure is vital for supporting growth, innovation and attracting new businesses1.
Why it matters for households
The wires and substations that carry electricity to a home are run by a distribution network operator, not by the supplier that bills the household. In Swindon's case that operator is SSEN Distribution, which covers central southern England and the north of Scotland. Reinforcement work of this kind is aimed at adding capacity and resilience to the local system, which is the physical constraint on how much new electrical load a property can add and how reliably supply is maintained.
For a household, the practical link is between network capacity and the low-carbon technologies SSEN names, such as heat pumps, EV chargers and rooftop solar with battery storage. A home's ability to add those depends on the capacity of the local network and, in some cases, on the supply into the property itself. The pilot SSEN mentions is intended to tell residents when that supply needs an upgrade, though the company has not reported how it will operate. Households wanting to understand the process for a supply upgrade can read the site's guide on how to apply for an electricity supply upgrade. The wider shift in how these networks are run and planned is covered in the guide to electricity distribution networks and the move to DSOs.
What happens next
The programme is scheduled to run until the turn of the decade. SSEN says it will contact homes and businesses in good time before improvements reach a specific area. No detailed schedule of works by location, and no completion date beyond the end of the decade, has been reported.
