The deal has a fee of £599.
Abbey has also more than halved the fee on its three-year fix up to 90% LTV to £495. It has a rate of 6.89% and comes with the Homebuyer Solution, offering a free basic mortgage valuation and £250 cashback on completion.
Alan Mathewson, managing director of Abbey for Intermediaries, said: “We are committed to supporting the housing market and first-time buyers, and expect there to be strong demand from intermediaries and their clients for this highly competitive new deal.
“Borrowers looking to take advantage of a longer-term fixed rate will also be able to benefit from the £500 fee reduction on our three-year fix.”
