Should I Get Critical Illness or Income Protection?
What's the difference between critical illness and income protection? This comparison explains how each works, which is better for your situation, and whether you need both. Critical illness = lump sum for specific conditions. Income protection = monthly income for any illness.
This guide compares critical illness vs income protection to help you understand the key differences. They serve different purposes and aren't directly comparable. Critical illness provides a large one-off payment for serious conditions, ideal for clearing mortgages. Income protection replaces your regular income if you can't work for any medical reason.
Cover is subject to policy terms and conditions.

Why This Matters for Your Mortgage
Understanding these details helps you make informed decisions during the mortgage process. Every element of your application—from deposits to documentation—affects your approval chances and the rates you can access.
Lenders assess applications holistically, weighing multiple factors together. Knowing what they look for allows you to present the strongest possible application. This is particularly important for non-standard situations where lender criteria varies significantly.
