Platform, the intermediary arm of Co-operative Bank, has returned to high-LTV lending with a five-year fix.

With a £999 fee and £250 cashback the rate comes in at 3.79 per cent and, with zero fee and £250 cashback, at 3.99 per cent.

Loan-to-income calculations have also been changed – at 75 per cent or lower the lender will use times 4.85 and above, times 4.49.

Co-operative Bank director of retail lending Carolyne Gregory says: “We have seen unprecedented volumes of mortgage applications in recent months and we are carefully managing the support and service we offer our customers.

“We are working hard to process existing applications and we have now taken the decision to reintroduce 90 per cent LTV products back into our range as we know that there is a consumer demand for higher LTV mortgages.

“We are continuing to monitor the wider market and will keep our product offering and rates in review to ensure our new mortgage products, and our remortgage and product switch options remain competitive in what continues to be a challenging time for consumers.”
