Doorstep delivery service Milk & More is adding 159 electric LDV EV80 vans to its fleet.
The firm says the deal will take its total EV fleet to over 500, with the rollout to be completed by the end of September.
It claims this will make it one of the largest operators of electric vans in the UK.
The vans have a 120 mile driving range, and can be fully charged in less than 90 minutes.
Milk & More deputy CEO Andrew Kendall said: “We are proud to have one of the largest fleets of electric vehicles in the country.
“Our new LDV electric vehicles represent our commitment to transforming the great British milkman into a modern, convenient delivery service which has a sustainable, environmentally friendly proposition at its heart.”
LDV UK and Ireland general manager Mark Barrett said: “Doorstep milk delivery is seeing a revival as people look to be more sustainable by buying their milk in reusable glass bottles.
“Milk & More is a company that prides itself on looking to the future and creating a greener business model.
“As such, the brand’s ethos is in line with LDV’s vision for the future and we are thrilled to be able to provide Milk & More with a fleet of EV80s, which will help to future-proof our business.”
