Lee Chiswell, head of Barclays mortgages, said: “Barclays was the first major UK lender to launch a green home mortgage in 2018, and we are pleased to be launching our green home buy-to-let mortgages, offering rate discounts to customers who are looking to purchase an energy efficient new build home to let, and rewarding them for making greener choices.
“We will continue to explore pioneering green products that meet the demands of our customers, to help them navigate the transition to a low-carbon economy and to encourage innovation in the lending sector.”
Since it launched its green home mortgage, Barclays has helped 4,000 customers to purchase a property with an A or B EPC rating by offering them a lower interest rate.
