The scheme will also include infrastructure for a further 300 future charge points across West Berkshire to ensure the network can grow as demand increases in public car parks and on-street locations.
Installations are expected to begin in 2026 and the council said locations would be confirmed once feasibility studies were completed.
Stuart Gourley, the authority’s executive member for environment and highways, called the project “a major step forward in delivering our climate and transport strategy”.
He said: “By expanding public EV infrastructure, we’re enabling more residents to support our net-zero goals by choosing sustainable travel and future proofing the district as demand grows.”
Connected Kerb chief executive Chris Pateman-Jones said the partnership was “all about giving every resident the confidence to go electric”.
The 20-year contract includes a revenue-share model, capped tariffs to keep charging affordable and “strong service level agreements to ensure performance and reliability”.
At the end of the contract, all infrastructure will transfer to the council for long-term public benefit.
