The ISA will be available via its branches and telephone banking from the 17 December, while online customers will be able to take out the product from early next year.
As per the terms of the ISA customers can save up to £1,200 in the first month and £200 thereafter. They will receive a 25% government top-up on the total saved between £1,600 and £12,000 when purchasing their first home.
Interest is paid monthly on 1st working day of the month and the rate is variable.
Steven Cooper, chief executive of personal banking at Barclays, said: “We are fully supportive of the government’s initiative to help even more people secure their first mortgage and home.
“We look forward to launching our Help to Buy: ISA later this month, helping future home-owners to achieve their ambitions."
