Both products come with an application fee of £195 and a completion fee of £800 and revert to Bank Base Rate plus 4.45% at the end of the fixed period.
Overpayments of up to 10% per annum are allowed without penalty and free legals and valuations are available for remortgages.
The products are available through the society’s direct customer service centre, branches and all intermediaries.
Kris Brewster, head of products at Skipton, said: “We are constantly monitoring both customer and market feedback and adjusting our product range to suit people’s developing needs as well as prevailing trends.
“With our new two-year product we’re offering a low rate for people who have managed to build up a decent equity cushion.
“At the same time we recognise that many people are looking for longer-term peace of mind against a backdrop of ongoing interest rate uncertainty, hence why we are introducing our new five-year fix at a lower rate to cater for that need.”
