The lender has launched a number of new products including a two-year fix at 1.34% and a two-year tracker at 1.29%, both for borrowers with a 40% deposit.
For those looking to fix for longer, a three-year deal at 1.99% and a five-year fix 2.34% are also available at 60% loan-to-value.
Platform products are only available through mortgage brokers and other financial intermediaries.
Rates in its buy-to-let range have also been cut, some by 0.15%. A two-year fix is available to borrowers at 2.44% while a two-year tracker is on offer at 2.14%.
Longer fixed deals include a three-year fixed rate product at 2.84%, while a five-year fix is available at 3.54%.
These buy-to-let deals are all available at 75% loan-to-value.
Stuart Beattie, head of mortgages at Platform, said the lender had developed the range in consultation with customers and mortgage brokers.
“We continue to maintain a competitive range of mainstream and buy-to-let products for brokers to offer to their clients,” he said.
“Supporting brokers and growing our mortgage business is a key part of our strategy.
“We will continue to work with the market as we develop products and services to ensure intermediaries are at the heart of our proposition.”
