With around 1.8 million fixed-rate mortgages due to expire in the UK in 2026, it’s not just buyers that need to find a good deal. Rises in interest rates in recent years mean that for many people remortgaging could bring an unpleasant shock with monthly payments much higher than on their previous deal.
Which? works with L&C which is the UK's largest fee-free mortgage broker to help consumers during times of market volatility. It has access to 1000s of deals from over 90 different lenders across the market and its advisers are on hand to help seven days a week, online or over the phone. At the successful completion of your mortgage application, L&C are paid a commission by the lender and will share a small part of the fee with Which? This sum is to help fund their not-for-profit mission and their campaign work as a champion for the UK consumer.
