📚 The Evolution of UK Mortgage Market

The UK mortgage market has undergone dramatic transformation since the Building Societies Act 1986, which deregulated the sector and introduced competition between banks and building societies. The introduction of the Mortgage Code in 1997 established consumer protection standards, while the 2007-2008 financial crisis led to stricter lending criteria and the creation of the Financial Conduct Authority in 2013. These changes reshaped affordability assessments, introducing stress testing and responsible lending practices that define today's market.

Modern UK mortgage regulation continues to evolve with changing economic conditions, technological advances, and political priorities. Recent developments include the Mortgage Market Review (MMR) in 2014, which introduced comprehensive affordability assessments, and the introduction of government schemes like Help to Buy and Shared Ownership. Brexit implications, interest rate volatility, and the COVID-19 pandemic have further shaped lending practices, highlighting the importance of staying informed about regulatory changes and regularly reviewing your mortgage strategy in this dynamic environment.
