In the UK, the cost of hiring a mortgage broker can vary based on several factors. Typically, mortgage brokers charge a fee or work on a commission or a combination of both. The fee can range from £300 to £500 on average. However, many brokers offer their services without charging a fee to the borrower, as they receive a commission from the lender when a mortgage is secured. This commission usually ranges from 0.35% to 0.45% of the total loan amount.

Always ensure that the mortgage broker you choose is regulated by the Financial Conduct Authority (FCA) to guarantee professional and ethical service.
