Coventry Building Society director of intermediaries Kevin Purvey said: “We’re delighted to launch our first ever range of four-year fixed residential mortgages.
“Our residential range now provides brokers with more options for clients looking for the stability of a fixed rate.
“In addition, all of our products are application fee-free and include a valuation of up to £670 for residential mortgages.”
According to Moneyfacts, Chelsea Building Society is the only other lender offering four-year fixed-rate mortgages on the open market, with its 65% LTV product at 1.64% with a £995 fee.
Lloyds Bank offers existing borrowers four-year deals, starting at 2.39%.
“The four-year fixed mortgage market is very limited right now, but it could be an option for lenders to branch into if competition is fierce for a five-year fixeds, where prices start at 1.59%,” Moneyfacts spokeswoman Rachel Springall said.
