The Nationwide Building Society is now offering a new twist on its existing four-year Flexclusive fixed rate mortgage, for those customers who hold a FlexAccount as their main current account.

The deal is priced at 2.89% for loans up to 60% LTV. Free valuation and standard legal services are also included.

The mortgage is available for both house purchase and remortgage customers and comes with a product fee of £900 (£400 for first-time buyers).

There is also a non-refundable £99 booking fee.

Meanwhile, its existing range of four-year Flexclusive fixed rate products without product fees are being cut by 0.10 percentage points and a new 60% LTV tier at 3.19% is being introduced.

“For Nationwide, market-leading headline rates aren’t just about attracting new customers,” said Tracie Pearce, head of group mortgages, products and pricing.

“We want to ensure that those who have the deepest relationships with the Society benefit most, and are rewarded for their loyalty. It’s yet another example of being ‘on your side’ and is at the heart of everything we do.”
