The RL0 category caters for self-employed borrowers, or those with complex income set-ups, who do not have adverse credit. Rates start at 2.45 per cent.
It also includes a Help to Buy version which starts at 3.2 per cent for a two-year fix at 75 per cent loan to value with a free valuation and £995 completion fee.
Alongside this, it has reduced rates on selected existing deals.
Peter Beaumont (pictured), deputy chief executive of the lender, noted that the RL0 category had been introduced as these borrowers require “increasingly sophisticated and granular pricing options”.
He added: “Reducing rates across our RL1 to RL4 products offers better value in those segments and the introduction of RL0 allows us to combine our experience with competitive rates, and provide a better deal for borrowers that don’t fit the box for high street lenders.”
