This replaces the previous product of 5.29 per cent.
At the same time the self-certification and buy-to-let flexible fixed rate products, which are available over two, three or five years, are increasing from 5.29 per cent to 5.59 per cent.
Keith Astill, managing director at UCB Home Loans, said: "Rapidly increasing swap rates mean that tracker products are becoming more and more popular with borrowers and the reduction to our buy-to-let three-year tracker places it extremely favourably in the market."
"We’re keeping the pricing of our product range simple, aligning the price of the new buy-to-let tracker with our self-cert three-year tracker and pricing all fixed products at the same rate.
"The rise in fixed rates is due to the significant increase in the cost of funding fixed rate products over the past few weeks. Many of our competitors have already put their rates up and our overall package remains extremely attractive, coupling good rates with low fees and flexibility.'
