Wrexham is on the cusp of an upgrade that’s designed around what matters to the people who live and work here: reliability, room to grow, and the confidence that the city’s infrastructure can keep pace with cleaner, modern technologies. This investment isn’t about cables for their own sake: it’s about giving homes, businesses and community spaces an electricity network that won’t hold them back.
Between April and October 2026, work will take place along the route from the Chester Street substation through to St Giles Crescent and nearby streets. Think of it as future‑proofing the parts of the network that were built for a very different era, long before electric vehicles, heat pumps or the scale of development Wrexham is now seeing.
What this means for Wrexham
Electricity demand in the city is rising fast. More people are choosing low‑carbon technologies, and Wrexham’s growth means more homes, more businesses and more activity relying on a network that was never designed for today’s pressures. Strengthening it now reduces the risk of outages, bottlenecks and delays to new developments.
Around 4.35 kilometres of new underground high‑voltage cable will be installed, alongside upgrades to existing equipment. Once complete, the network will be better placed to:
- Keep power reliable for homes and businesses
- Support new development across the city centre
- Enable cleaner technologies such as EVs, heat pumps and local renewable generation
Cities across the UK are going through similar modernisation, not because it’s fashionable, but because it’s the only way to stay ahead of rising demand and avoid bigger, more disruptive problems later.
Where work will happen
The programme runs for around six months, but each street is only affected for a short period as the team moves along the route. If timings shift, updates will follow.

Managing traffic and disruption
Nobody enjoys roadworks, and the aim is to keep Wrexham moving while essential upgrades take place. For safety, there will be moments where temporary traffic lights, lane closures or parking restrictions are unavoidable but the focus is on keeping these as short and predictable as possible.
To reduce disruption, the team will:
- Work in short sections so each area is affected for the minimum time
- Maintain access for residents, businesses and emergency services wherever possible
- Reinstate roads quickly once work is complete
Coordination with the local authority helps avoid overlapping works and unnecessary congestion.
Keeping you informed
Residents and businesses will receive updates as the programme progresses. Live information is also available at https://one.network.
This upgrade is about giving Wrexham a network that can support the city’s ambitions, reliable today, ready for tomorrow, and resilient for decades.
