How to Avoid Over- or Under-Insuring
Reviewed and updated
The right amount of insurance protects you fully without wasting a penny.
Overview
Good insurance is a balance. Underinsuring leaves you exposed to losses you cannot afford to absorb. Overinsuring — buying cover you do not really need, or duplicating cover you already have elsewhere — quietly wastes money every single month.
The goal is to cover the big, genuinely unaffordable risks fully, and stop there.
Core Concept
The principle is to insure what you cannot afford to lose, and self-insure the rest by keeping an emergency fund. Small losses you could pay for from savings do not need a policy; large losses that would set you back for years do.
This matters because every premium is a recurring cost. Cover the genuine threats fully, and you can confidently skip the add-ons and minor policies that drain money without protecting much.
Applied Insight
Imagine you have three small protection-plan add-ons — on a phone, a washing machine, and a laptop — each a few pounds a month. Together they might cost 200 GBP a year to cover items you could replace from savings.
Cancelling them and keeping that 200 GBP in your emergency fund means you self-insure those small risks for free, while your money stays available for anything. Meanwhile, you keep the cover that really matters, like home and health.
Practical Walkthrough
The mistake is collecting lots of small policies and add-ons while leaving a big risk uncovered — paying to protect a phone while having no contents or life cover.
Once a year, list every insurance and protection plan you pay for. Cancel the small ones you could self-insure, check the big risks are properly covered, and make sure no two policies cover the same thing. The result is fuller protection for less money.
Key Takeaways
Underinsuring leaves you exposed; overinsuring wastes money.
Insure what you could not afford to lose, and self-insure the rest.
An emergency fund lets you safely skip small policies and add-ons.
Review your cover yearly and remove duplicates.
Next Steps
List every insurance and protection plan you pay for, then cancel the small ones you could self-insure and confirm your big risks are properly covered.
