A no-claims discount can make private health insurance considerably cheaper if you go for several years without making claims.
But health insurance no-claims discounts do not work in exactly the same way as car insurance.
Depending on the insurer, your discount may move up or down through a series of levels. The effect of a claim may depend on:
- whether the insurer actually paid anything;
- how much the insurer paid;
- which person on a family policy claimed;
- whether you bought no-claims protection;
- the particular health-insurance product you have.
This can create an awkward situation.
You may have insurance specifically so that you can use private healthcare when you need it, yet making a claim can reduce your discount and contribute to a higher renewal premium.
For small claims, some people therefore wonder whether they would actually be better paying for treatment themselves.
Sometimes that makes financial sense.
Sometimes it can backfire badly — particularly if protecting a discount causes you to delay necessary investigation or treatment.
This guide explains how private health insurance no-claims discounts work in the UK, what happens after a claim, when paying privately may make sense and why your premium can still rise even after a claim-free year.
What Is a Health Insurance No-Claims Discount?
A no-claims discount, usually abbreviated to NCD, is a reduction applied to your health-insurance premium based partly on your claims history.
The general idea is simple.
If the insurer pays no claims for you during the relevant period, your discount may increase.
If the insurer pays a claim, your discount may stay the same or decrease.
The exact mechanism differs between insurers.
For example, Bupa currently uses a numbered no-claims scale on some individual products. With Bupa By You, the scale runs through 14 levels and the maximum discount is 70%.
AXA Health also uses a scale, but its own guidance makes clear that the number of levels and the amount a customer moves after a claim can depend on the particular plan.
This means you should never assume that a friend's experience with another insurer applies to your own policy.
Your policy handbook and renewal documents matter.
What Happens to Your Discount When You Claim?
This depends heavily on the insurer.
Some insurers use the value of the claim.
For example, Bupa's current Bupa By You system says:
| Amount paid in relevant claims | Effect on NCD level |
|---|---|
| £0 | Move up one level |
| £0.01–£300 | Stay at the same level |
| £300.01–£1,200 | Move down two levels |
| More than £1,200 | Move down three levels |
Other Bupa products use different scales, which reinforces why you need to check the rules attached to your own cover.
AXA Health's Health For You documentation takes another approach. It says that when someone makes a claim, that person's discount falls by three levels at renewal, regardless of how many separate claims are made during that policy year.
The lesson is straightforward:
There is no universal UK no-claims formula.
The same £500 claim could have a very different renewal effect with two different policies.
Does Making a Claim Automatically Increase Your Premium?
Not necessarily immediately, and not necessarily by a predictable amount.
Your no-claims discount is only one part of the premium calculation.
Health-insurance prices can also change because of:
- your age;
- medical inflation;
- increasing hospital costs;
- new drugs and treatments;
- changes to Insurance Premium Tax;
- your chosen hospital list;
- your postcode;
- policy changes.
Bupa explicitly warns customers that premiums can still increase even when their no-claims discount improves because healthcare costs, treatment technology and age continue to affect the underlying premium.
This is an important point.
A 60% no-claims discount does not mean your premium must be lower than it was last year.
The insurer first calculates the underlying cost of providing the cover and then applies the discount according to the policy rules.
If that underlying cost rises substantially, the final premium can rise as well.
For more on the wider factors that affect pricing, see our guide to how much private health insurance costs in the UK.
When Can a No-Claims Discount Backfire?
The biggest problem arises when people begin treating the discount as something more important than the insurance itself.
Private medical insurance exists to protect you from potentially expensive medical costs.
If fear of losing your NCD causes you to avoid using the policy when you genuinely need it, the incentive is working against the purpose of the cover.
For example, imagine you develop persistent symptoms and a specialist consultation plus scans could cost well over £1,000.
Trying to preserve a no-claims discount by paying for everything yourself could leave you spending substantially more than the eventual change in premium.
Worse, delaying investigation because you do not want to “lose your discount” could delay diagnosis.
Bupa specifically tells customers not to delay treatment because of the effect a claim could have on their NCD.
That is sensible advice.
Your health should not be managed around an insurance discount.
When Might Paying for a Small Treatment Yourself Make Sense?
There are situations where it is reasonable to compare the cost of claiming with simply paying privately.
Suppose the treatment is inexpensive, optional and comfortably affordable.
Examples might include:
- a relatively inexpensive consultation;
- a basic diagnostic test;
- minor outpatient treatment;
- something whose cost falls close to your excess.
If your excess is £250 and the treatment costs £275, the insurer may only contribute a small amount anyway.
Depending on your insurer's NCD rules, claiming that small balance might provide little immediate benefit.
Some policies specifically avoid penalising claims that fall entirely within the excess.
Bupa, for example, says claims that fall entirely within the member's excess do not count when assessing the no-claims discount on certain products.
Aviva similarly explains that if the treatment costs less than your excess and no claim is made, the NCD is unaffected.
This interaction between the excess and NCD is worth checking before treatment.
Our guide to private health insurance excesses explains how different excess levels work.
Can You Pay Back a Claim to Protect Your Discount?
With some insurers and products, yes.
This is sometimes known as buying back a claim.
AXA Health currently tells members that if they have claimed during the year, they may be able to repay the claim around renewal time to keep their NCD at a higher level.
AXA specifically notes that where a claim is small, the premium saving from restoring the discount may sometimes exceed the amount repaid.
This creates a useful opportunity.
You can initially use the insurance rather than making a rushed decision about self-paying.
At renewal, once you know:
- how much the insurer actually paid;
- how the claim affected the NCD;
- what the renewal premium will be;
you may be able to decide whether repaying the claim is worthwhile.
Not every insurer or product offers this option, so check before assuming it is available.
What Is No-Claims Discount Protection?
Some policies allow you to pay an extra premium to protect your no-claims discount.
The principle is similar to protected NCD on motor insurance.
You pay more upfront so that an eligible claim does not reduce the discount level in the usual way.
Aviva currently offers protected no-claims discount as an optional feature on its health insurance.
AXA Health also says protection is available on some plans once members have reached the relevant maximum discount.
But “protected no-claims discount” does not necessarily mean:
“My premium cannot increase if I claim.”
It generally means that the particular NCD level is protected according to the product rules.
Your underlying premium can still increase for other reasons.
Age and medical inflation do not disappear because the NCD is protected.
And insurers may place limits on how frequently protection can be used.
For example, Aviva currently says that after NCD protection is triggered, a member must be claim-free for one year before the protection can be used again.
Why Family Policies Can Be Less Punitive Than You Expect
On some individual and family health-insurance policies, each person has their own no-claims discount.
This means one person's claim may not automatically reduce everyone else's discount.
Bupa states that on relevant products it calculates each person's NCD separately.
AXA Health similarly says each person covered can have their own discount level.
So if a family of four is insured and one child has treatment, it does not necessarily mean the entire family's no-claims position collapses.
However, the overall family premium can still change for several reasons.
Always check how your specific family policy treats claims.
For more on policy structure, see our guide to individual vs family health insurance.
Should You Avoid Claiming for Outpatient Treatment?
Not automatically.
Outpatient treatment is where people are most likely to question whether claiming is worthwhile because the individual costs can appear manageable.
A specialist appointment might cost a few hundred pounds.
But an investigation can quickly expand into:
- consultant appointments;
- MRI or CT;
- blood tests;
- follow-up consultations;
- physiotherapy;
- minor procedures.
What looks like a £250 problem can become a £1,500 problem surprisingly quickly.
If you choose to self-pay for the first appointment purely to protect your NCD, check what happens if subsequent tests become expensive.
Some insurers require pre-authorisation and may have rules about when they become involved in an existing episode of treatment.
It is therefore sensible to speak to the insurer before assuming you can self-pay the first part and claim later without difficulty.
See our guide to outpatient cover on private health insurance for more detail on specialist, scan and test limits.
What Should You Check Before Deciding Whether to Claim?
Before paying privately simply to preserve your discount, ask your insurer:
- What NCD level am I currently on?
- What discount percentage does that represent?
- How would this claim affect my level?
- Does the amount of the claim matter?
- Would treatment falling within my excess count?
- Does this benefit count towards the NCD at all?
- Can I buy back the claim later?
- Do I have protected NCD?
- What would my renewal NCD become if the claim were paid?
Do this before assuming that a claim will “destroy” your discount.
Some claims may have no effect at all.
Others may reduce the discount much less than you expect.
And with expensive treatment, the financial value of having the insurer pay the claim can vastly outweigh the renewal impact.
If you do claim, make sure you follow the insurer's authorisation process. Our guide to making a health insurance claim in the UK explains the usual steps.
Can You Switch Insurer After Making a Claim?
You can apply to another insurer, but switching is not always as simple as finding a cheaper quote.
AXA Health notes that a no-claims discount generally cannot simply be transferred to a new insurer in the same way as people sometimes expect from car insurance.
More importantly, changing insurers can affect the treatment of medical conditions that developed while you were with the previous insurer.
The implications depend on:
- the underwriting method;
- whether the new insurer offers continued personal medical exclusions or similar transfer terms;
- your claims history;
- existing or ongoing conditions.
A cheaper premium is not necessarily a better deal if changing policy introduces exclusions affecting something you are currently being treated for.
Before switching, read our guide to moratorium vs full medical underwriting and check exactly how ongoing conditions will be treated.
It is also worth reviewing the broader policy rather than focusing entirely on NCD. Our guide to choosing private health insurance in the UK covers outpatient limits, cancer cover, hospital lists, exclusions and excesses.
Frequently Asked Questions
Do all UK health insurers offer a no-claims discount?
No. Product structures vary. Some insurers use explicit no-claims scales, while others price claims experience differently. Always check the policy you are actually buying.
How much can a no-claims discount save?
It depends on the insurer and product. Some products have substantial maximum discounts after several claim-free years. Bupa By You, for example, currently has a 14-level scale with a maximum discount of 70%.
Will one health-insurance claim wipe out my whole discount?
Usually not. Many policies reduce the discount by a limited number of levels rather than removing it entirely. The exact change depends on your insurer and policy.
Does the size of the claim matter?
Sometimes. On some Bupa products, larger claims result in a greater fall in the NCD level. Other insurers may use a different system.
Does a claim below my excess affect my no-claims discount?
Often not if the insurer pays nothing. However, the policy wording should be checked because insurers structure NCD rules differently.
Can I pay for treatment myself instead of claiming?
Yes. You are not normally obliged to claim simply because you have insurance. For inexpensive treatment, self-paying can sometimes make sense, but compare the cost with the potential effect on your renewal rather than assuming it is always cheaper.
Can I pay back a claim later?
Some insurers allow this. AXA Health currently allows some members to repay a claim around renewal to preserve a higher NCD level.
What is protected no-claims discount?
It is an optional feature on some policies that protects your discount level from an eligible claim according to specified rules. It does not guarantee that your total premium will stay unchanged.
Can my premium rise even if I make no claims?
Yes. Age, hospital costs, medical inflation, new treatments, taxation and other factors can increase the underlying premium even if your NCD improves.
Can my premium rise even with protected NCD?
Yes. NCD protection generally protects the discount level, not the entire premium.
Does my partner's claim reduce my own NCD?
Not necessarily. Some family policies maintain separate NCD levels for each insured person.
Should I avoid a £200 claim to protect my discount?
Possibly, but only after checking your specific rules. Some policies may not reduce your NCD at all for a small claim. Self-paying solely because you assume every claim causes a large premium increase can therefore be a mistake.
Should I avoid claiming for expensive treatment?
Usually the value of insurance becomes greatest precisely when treatment is expensive. Preserving an NCD while paying thousands of pounds yourself may defeat the purpose of having insurance.
Can making a claim affect next year's premium immediately?
The effect usually appears at renewal rather than as an immediate mid-year premium increase. Insurers use a defined calculation period, which may not exactly match the policy year.
What happens if a provider sends the invoice late?
The claim may fall into a later NCD calculation period depending on when the insurer approves or pays it. This is another reason the effect is not always visible at the next renewal.
Is health insurance still worth using if claims increase premiums?
Yes, when the treatment cost or value of rapid private access justifies it. Insurance is primarily there to protect against healthcare costs and provide access to treatment, not to preserve the largest possible discount.
What is the biggest mistake people make with no-claims discounts?
Treating the discount as more important than their health or the purpose of the insurance. A no-claims discount can be financially useful, but it should not encourage people to delay necessary medical care or pay large treatment bills unnecessarily.
