Transport for London says the lifts are the “first milestone in a major upgrade of the station” which will also create a new, alternative step-free route. New ticket gates and a larger staircase have already been installed.
Heidi Alexander, Deputy Mayor for Transport, said: “The introduction of step-free access at Finsbury Park will make a big difference to the daily lives of passengers who use this busy station every year, particularly disabled people, older people and those with young children.
“Our transport network should be accessible to all Londoners and visitors, so I am delighted that we continue to invest record amounts to improve stations across the city.”
Caroline Sheridan, Director of Renewals and Enhancements for London Underground, added: “It is vital that we continue to do as much as possible to improve the accessibility of the Tube network.
“Finsbury Park is one of our busiest Tube stations and a crucial interchange between two of our busiest lines, so making the station step-free will make a real, positive difference to thousands of customers every day.”
