Insurance Jargon You Need To Know
Insurance policies are full of technical terms that can feel confusing — especially when you're making a claim. Understanding the language used by insurers, brokers, and loss adjusters can help you avoid costly misunderstandings and ensure you receive everything you're entitled to.
Here's a plain-English guide to the most important insurance jargon you need to know in the UK.

Core Policy Terms Explained
These are the fundamental terms you'll encounter in any insurance policy. Getting these right is the first step to understanding your cover.
Policyholder
The policyholder is the person or business that owns the insurance policy. This is the individual entitled to make a claim under the terms of the contract.
Premium
Your premium is the amount you pay (monthly or annually) for your insurance cover. The cost depends on the level of risk and the type of cover selected.
Sum Insured
The sum insured is the maximum amount your insurer will pay for a particular section of cover (e.g., buildings or contents). If your property is underinsured it can significantly reduce your payout.
Indemnity
Indemnity means putting you back in the same financial position you were in before the loss — no better, no worse. Most insurance policies in the UK operate on an indemnity basis.
New for Old
Some contents policies offer "new for old" cover, meaning damaged items are replaced with brand-new equivalents rather than factoring in depreciation. Always check your policy type.
Betterment
Betterment occurs when repairs improve your property beyond its pre-loss condition. Insurers may deduct a contribution if you are deemed to be in a better position after repairs are completed.
Excess & Underinsurance
Excess is the amount you must contribute towards a claim before the insurer pays out. There are usually two types:
- Compulsory excess – Set by the insurer and non-negotiable
- Voluntary excess – Chosen by you to reduce your premium
If your excess is £500 and your claim is £10,000, the insurer will typically pay £9,500.
Underinsurance & The Average Clause — If your home is insured for less than its actual rebuild value, the insurer may apply the average clause and reduce your payout proportionally.
True rebuild cost: £400,000
Insured for: £200,000 (50%)
Claim value: £100,000 → Insurer pays only £50,000
This is one of the most misunderstood — and costly — policy terms. We check your cover levels as part of every claim.
Loss Adjuster vs Loss Assessor
This is one of the most important distinctions in any insurance claim. Understanding who works for whom can make a significant difference to your settlement.
Loss Adjuster
A loss adjuster is appointed by your insurer to investigate and assess your claim on their behalf. Their role is to validate and manage the cost of the claim for the insurance company.
- Paid by the insurer
- Represents the insurer's interests
- May minimise your settlement
- Large firms: Crawford & Company, Sedgwick
Loss Assessor
A loss assessor (or public loss assessor) works exclusively for the policyholder. They prepare, present, and negotiate your claim to maximise your full entitlement under the policy.
- Paid from your settlement — No Win, No Fee
- Represents your interests only
- Maximises your payout

What Is a Peril?
A peril is the specific cause of loss or damage covered by your insurance policy. If the cause of damage isn't listed as an insured peril, the claim may be declined by your insurer.
Common insured perils in the UK include:
Escape of Water is one of the most common household claims in the UK — it refers to water damage caused by leaking pipes, tanks, or appliances. It does not usually cover flooding from rivers or surface water, which is classified separately.
If the cause of damage isn't listed as an insured peril in your policy, your claim may be declined. Vanguardo will check your policy wording in full and challenge any incorrect rejections on your behalf.
Understanding Claim Repudiation
If an insurer rejects your claim, this is known as repudiation. This doesn't necessarily mean the insurer is right — many repudiations are successfully challenged.
Common reasons for claim repudiation include:
If you disagree with the insurer's decision, you can raise a formal complaint and — if unresolved — escalate it to the Financial Ombudsman Service.
As your loss assessors, Vanguardo can review rejected claims, identify grounds for appeal, and re-present your case to ensure a fair outcome.
