A five-year fixed buy-to-let rate is also available at 3.79% up to 75% LTV with a £999 fee.
Vernon’s head of intermediary sales, Tom Gurrie, said: “We want to make it easy for all brokers to do business with us. Over the last two years we’ve steadily expanded our intermediary distribution – completely removing the postcode restriction marks the last step to becoming a nationally focused lender.
“We look forward to helping even more brokers find competitive products and innovative funding solutions for all their clients who would benefit from an individual, personal approach to their particular situation, rather than a one-size fits all approach.”
