Income Protection in the UK: How It Works + How Much You Can Insure

A practical guide to UK income protection: own occupation, deferral periods, benefit periods, exclusions, and how insurers calculate the maximum benefit.

The simple answer

Income protection pays a monthly benefit if you can't work due to illness or injury, after a waiting period (deferral). It's designed to protect your ability to pay the bills.

Key takeaways

• Choose a deferral period that matches sick pay + savings
• "Own occupation" definitions matter a lot
• Benefit is usually based on earned income and insurer rules
• You can tailor how long it pays (e.g., 2 years vs to retirement)

How income protection works (in plain English)

1. You choose a monthly benefit (within insurer limits)
2. You choose a deferral period (e.g., 4, 13, 26 weeks)
3. If you can't work due to illness/injury, you claim
4. After the deferral, the policy pays a monthly income while you remain eligible

How much can you insure?

Insurers typically set maximum benefits based on a proportion of your earnings (and they may reduce the percentage at higher incomes). The exact amount varies by insurer and policy type.

A sensible approach:

• Work out your essential monthly outgoings
• Compare to your sick pay, savings, and partner income
• Choose a benefit that closes the gap without overshooting

Three choices that drive quality (and price)

1) Definition of incapacity: "own occupation"

This is the big one. It generally means you're assessed against your own job, not "any job". The wording varies, so it's important to choose carefully.

2) Deferral period

Shorter deferral = higher premium.

Choose based on real-world resilience:

• Strong sick pay + savings → longer deferral often works well
• Self-employed → shorter deferral may be needed

3) Benefit period

How long it pays:

• 2 years / 5 years / to a set age (e.g., 65/68)

Example: choosing a deferral

You have:

• 3 months emergency fund
• Employer sick pay: 8 weeks full pay

You might choose a 13-week deferral so your sick pay + savings cover the waiting period.

Common mistakes

• Choosing the cheapest policy without checking definitions
• Underestimating how often illness (not accidents) causes long absences
• Setting the benefit without considering what you already have (sick pay, savings)

Mini FAQs

Is it worth it if I have savings?

Savings are great — income protection is about not draining them.

Do I need it if I'm healthy?

That's often when it's most affordable (and easiest to arrange).
