The UK Government has funding available to help businesses purchase and install electric vehicle charging points. A maximum of 75% of the cost, up to £350 per socket, is available. All businesses can use it to provide chargepoints for their staff or fleets, and charities and small accommodation businesses can also use it to provide chargepoints for their guests or visitors. More information is available at Workplace Charging Scheme.
