The Bank said the changes, which come into effect today, were introduced to ensure its products were consistent with market conditions.

In the purchase mortgage range, rate increases of up to 0.35% will now apply on selected two-year deals and some five-year products will see hikes of up to 0.25% for new customers.

It is also increasing rates by up to 0.26% on selected two-year deals and by up to 0.15% on selected five-year deals for existing customers switching.

NatWest also announced it would be reintroducing a selection of broker exclusive two and five-year fee-based purchase products.

Mark Bullard, head of sales, said: “We are pleased to reintroduce some broker exclusives as well taking the opportunity to review our proposition to ensure it is in line with current market conditions.”
