MODULE 1: How UK Mortgages Really Work

Understanding how mortgages work in the UK is a crucial first step for anyone researching home buying, refinancing, or long-term property finance. Yet many people begin the process without a clear picture of how mortgages are structured, how lenders assess applications, or how the overall journey fits together.

This module provides a clear, educational overview of UK mortgages, focusing on how the system works rather than promoting products or outcomes. It is intended to support general understanding only and does not provide mortgage advice or recommendations.

In this module, you’ll explore:

  • What a mortgage is and why it exists
  • How the UK mortgage system is organised
  • Who is involved in the mortgage process and what their roles are
  • How a mortgage typically progresses from early planning to completion

The aim is to explain mortgages as a process, not a single transaction. Many of the decisions that affect mortgage outcomes happen well before an application is submitted, and understanding this structure can make later stages easier to navigate.

This module is divided into three chapters. It starts with the basic definition of a mortgage, moves into an overview of the UK mortgage system, and then explains the full mortgage lifecycle. Each chapter introduces a set of topics that explore individual concepts in more detail.

If you’re new to mortgages, it’s best to begin with Chapter 1.1, then work through the chapters in order to build a complete picture of how UK mortgages really work.
