Overview
The UK mortgage market is regulated by the Financial Conduct Authority under MCOB — the Mortgages and Home Finance: Conduct of Business sourcebook — which sets the rules for how lenders must assess affordability, disclose terms, and treat borrowers throughout the life of a mortgage. Whether you are buying your first home, remortgaging to a better deal, or navigating a problem with an existing mortgage, the system has specific rules that determine what lenders can do, what they must do, and what your rights are at each stage.
This page serves as a central hub for our detailed mortgage guides. Each one explains a specific aspect of the process, the regulatory framework behind it, and the practical implications for borrowers in England, Wales, Scotland, or Northern Ireland.
