Your simple, friendly A–Z guide to protection jargon

Talking about protection isn’t exactly fun… but understanding it is really important.

When people start looking at life insurance, income protection or critical illness cover, they’re suddenly hit with words like “underwriting,” “deferred period,” “waiver of premium,” and “exclusions.” No wonder it feels overwhelming.

You’re not meant to know this stuff — we weren’t taught it at school.

So I’ve created this A–Z Protection Jargon Buster to explain everything in simple, human terms, with real examples, just like I would on a call with you. No scary insurance speak — just clear explanations you can actually understand.

A — Protection Terms Explained

Additional Benefits
Extra features included in some policies, such as fracture cover, rehabilitation support, or second medical opinions.

Accelerated Terminal Illness Benefit
A feature in most life insurance policies that pays out early if you’re diagnosed with a terminal illness.

B — Protection Terms Explained

Back to Day One
In some income protection policies, if you return to work and then fall ill again with the same condition, the waiting period may reset — meaning you start the deferral period again.

Benefit Amount
The amount your policy would pay out — either monthly (income protection or Family Income Benefit) or as a lump sum (life or critical illness).

Beneficiary
The person (or people) who will receive the payout from your policy.

C — Protection Terms Explained

Claim
When you officially ask your insurer to pay out on your policy.

Claim Form
The paperwork you (or your family) complete to start a claim.

Claim Assessor
The person at the insurance company who reviews and decides on your claim.

Claim Payout Time
How long it takes for the insurer to pay once your claim has been approved.

Children’s Cover
Cover included with some critical illness or life policies that pays out if a child becomes seriously ill or passes away.

Cooling-Off Period
Usually 30 days after you start a policy where you can cancel and get your money back.

Critical Illness Cover (CIC)
A policy that pays a lump sum or monthly payments if you’re diagnosed with a specified serious illness (such as certain cancers, heart attack, or stroke).
👉 Example: You’re diagnosed with a covered illness — the policy pays £100,000 in one go.

D — Protection Terms Explained

Death in Service
Life cover provided by your employer, usually a multiple of your salary (e.g. 4x or 6x).

Decreasing Term Assurance
Life insurance where the payout reduces over time — commonly used to match a repayment mortgage.
👉 Example: As your mortgage balance falls, so does the cover amount.

Deferral Period (Waiting Period)
For income protection, this is how long you must be off work before payments start (e.g. 4, 8, 13, 26, or 52 weeks).
👉 Example: If you choose 13 weeks, the insurer pays from week 14 onwards.

E — Protection Terms Explained

Executive Income Protection (Executive IP)
A type of income protection policy that is owned and paid for by your limited company, rather than you personally.

👉 In simple terms: your business pays the premium, not you from your personal bank account — which can be tax-efficient for directors.

👉 Example: You are a company director and become too ill to work. The policy pays a monthly income to your company, which can then be used to continue paying you a salary or dividends.

This is different from personal income protection, which pays directly to you.

Exclusions
Conditions or situations that your policy does not cover.
👉 Example: A pre-existing back problem might be excluded.

F — Protection Terms Explained

Family Income Benefit (FIB)
A type of life insurance that pays your family a monthly income instead of one big lump sum if you die during the policy term.

👉 Example: £2,000 per month until your youngest child turns 21.

This is often used to:

• replace lost income
• cover household bills
• support children’s upbringing
• avoid your family having to manage a large lump sum all at once

Financial Underwriting
Checks the insurer does to make sure the amount of cover you want is reasonable based on your income.

Fracture Cover
A benefit that pays a small amount if you break certain bones.

G — Protection Terms Explained

Guaranteed Premiums
Your premiums won’t increase over time (unless you choose to increase cover with inflation).

Guaranteed Insurability Option
The option to increase your cover later without more medical questions (for example after marriage or having a baby).

H — Protection Terms Explained

Heart Attack Definition
Each insurer defines what counts as a “heart attack” for a claim — definitions can differ between providers.

Whole of Life Insurance
Life cover that lasts your entire lifetime, rather than for a fixed term.

I — Protection Terms Explained

Income Protection (IP)
A policy that pays you a monthly income if you can’t work due to illness or injury.
👉 Example: You’re off sick long-term — the insurer pays you until you recover, retire, or the policy ends.

Indexation (Inflation Protection)
Your cover increases each year in line with inflation, so it doesn’t lose value over time. Think of it like a Fredo — it used to cost 20p, and look how much they cost now!

Independent Medical Examination
A doctor appointed by the insurer may assess you if needed during underwriting or a claim.

J — Protection Terms Explained

Joint Life Policy
One policy covering two people that pays out once — then ends.
Often cheaper, but less flexible than having separate policies.

L — Protection Terms Explained

Level Term Assurance
Life insurance where the payout stays the same throughout the policy term.
👉 Example: £300,000 cover for 25 years.

Loading (Premium Loading)
An increase in your premium because of health, lifestyle, or occupational risks.

M — Protection Terms Explained

Mental Health Exclusion
Some policies may exclude certain mental health conditions — this depends on underwriting.

Misrepresentation / Non-Disclosure
If you don’t tell the insurer something important about your health, your claim could be affected.

Moratorium Underwriting
A type of underwriting where pre-existing conditions are excluded for a set period unless you’ve been symptom-free.

N — Protection Terms Explained

Non-Medical Limits
The maximum amount of cover you can get without needing medical tests.

O — Protection Terms Explained

Own Occupation
An income protection definition meaning you’re paid if you can’t do your specific job — the best level of cover.

Other (Suited) Occupation
You’re only paid if you can’t do any job suited to your experience — usually less generous.

P — Protection Terms Explained

Partial Payment
Some critical illness policies pay a smaller amount for less severe conditions.

Policy Schedule
The document showing your cover details, premiums, and terms.

Policy Wording
The legal document explaining exactly what is and isn’t covered.

Pre-Existing Conditions
Any medical condition you had before taking out the policy.

Premium
The amount you pay each month for your cover.

Proportionate Benefit
In income protection, your payout may be reduced if you return to work part-time.

Q — Protection Terms Explained

Qualifying Period
The time you must have the policy before certain benefits apply (varies by insurer).

R — Protection Terms Explained

Rehabilitation Support
Help from the insurer to get you back to work (physio, counselling, occupational therapy).

Reviewable Premiums
Premiums (monthly payments) that can increase over time rather than being fixed.

S — Protection Terms Explained

Serious Illness Cover
Another term sometimes used instead of Critical Illness Cover.

Single Life Policy
A policy covering just one person.

Sum Assured
The amount of cover you’ve chosen.

T — Protection Terms Explained

Terminal Illness Benefit
Pays out early if you’re diagnosed with a terminal illness.

Trust (Placing in Trust)
A legal arrangement so your payout goes directly to your chosen beneficiaries — often avoiding probate delays.

Total Permanent Disability
A definition used in some policies if you’re permanently unable to work.

U — Protection Terms Explained

Underwriting
The insurer’s process of assessing your health, job, and lifestyle before offering cover.

Underwriter
The person who decides whether to accept your application and on what terms.

W — Protection Terms Explained

Waiting Period (Deferred Period)
Same as deferral period — how long you wait before income protection starts paying.

Waiver of Premium
If you’re too ill to work, the insurer pays your premiums for you so your cover stays in place.
👉 Example: You’re off sick long-term — you don’t have to keep paying, but your policy continues.

Still confused? That’s completely normal — most people are at this stage.

Protection can feel complicated, but it doesn’t have to be scary. It’s really about one simple thing: making sure you and your family are okay if life throws something unexpected your way.
