British DC fast-charging company InstaVolt has officially opened “the largest and most advanced ultra-rapid charging Superhub in the UK.”
The UK charging Superhub, which hosts 44 160 kW DC fast chargers, is in Winchester, near the A34 and close to junction 9 of the M3. It’s a crucial connection point for EV drivers traveling between the Midlands, Oxford, and the Southwest of England.
The site has drive-through bays for big lorries and vehicles towing trailers, extra-long spaces for electric vans, and dedicated accessible charging spots. The chargers cost users 85p per kilowatt at peak, and an off-peak charge of 54p per kilowatt.
The Winchester Superhub is InstaVolt’s first charging hub to pair EV chargers directly with onsite solar and battery storage. It’s powered by 870 solar panels that work together with a 960kW/4MWh battery storage system and renewable grid energy to keep chargers humming at full capacity. By integrating solar and storage, InstaVolt cuts down grid reliance, making it easier to roll out big, ambitious sites like this without burdening the grid.
Delvin Lane, CEO of Basingstoke-based InstaVolt, said, “This site is … a milestone in innovation, marking our first-ever location where we are generating our own renewable energy – pushing the boundaries of sustainability and self-sufficiency in EV charging.”
There’s a Starbucks onsite, along with 24/7 toilet facilities, a children’s playground, a dog walking area, and an air and water machine for vehicles. It has CCTV and security services and the site is well-lit with low-level LED lighting.
Transport Secretary Heidi Alexander, who visited the Superhub on March 17, said, “This government is spending £2.3 billion, alongside £6 billion of private investment, to supercharge the switch to greener vehicles, and only last week confirmed the availability of 75,000 public charge points – as we install a new one at a rate of one every 29 minutes.”
According to Zapmap, as of the end of February 2025, there were 75,675 EV charging points across the UK, 38,350 charging locations, and 110,588 connectors.
