How couples' health insurance works
Almost every UK insurer lets you add a partner to your policy. You'll have one set of policy documents, one premium and one renewal date. Behind the scenes, though, each of you is still priced and underwritten individually — based on your own age, medical history and, where relevant, smoking status.
Joint policy or two separate ones?
A joint policy suits you if:
- You want one set of paperwork and one renewal date
- You're happy with the same level of cover
- The insurer offers a discount for adding a partner
Separate policies can suit you better if:
- There's a big age gap, and one partner would get a better price elsewhere
- You want quite different levels of cover — for example one of you wants extensive outpatient cover and the other a low-cost plan
- One of you has cover through work and only the other needs a personal policy
- You'd rather one person's claims couldn't affect the other's no-claims discount
The only way to know which is cheaper is to compare both ways.
Shared vs individual no-claims discounts
This is the detail most couples miss. On some policies the no-claims discount is shared, so a claim by either of you can raise the renewal price for both. Others — Aviva, for example — give each person their own no-claims discount. The Exeter's structure means claims under £300 don't affect your discount at all. If either of you expects to claim, this can matter more than the starting price.
Where you live matters
Most insurers charge more in areas where private treatment costs more, particularly London and the South East. Freedom Health Insurance is one of the few that prices the same regardless of postcode, which can make it competitive for couples in higher-cost areas.
If one of you has cover at work
If one partner has employer health insurance, check whether the scheme lets you add a partner. It's sometimes cheaper than a separate personal policy — but because the cover usually ends if the employee leaves the job, compare it with a standalone plan too.
If you separate
Insurers can normally split a joint policy into two individual policies, usually on continuing underwriting terms so neither of you loses cover you've built up. Contact the insurer promptly to arrange it.
Questions and answers
Is a joint policy cheaper than two separate policies?
Not always. Each partner is usually priced on their own age and circumstances, so a joint policy often costs roughly the same as two individual ones. The main advantages are convenience and, with some insurers, a multi-person discount. If you're very different ages or want different levels of cover, two separate policies from different insurers can work out cheaper.
Do we have to be married to take out a joint policy?
No. Most insurers accept partners living together, whether married, in a civil partnership or not. Check the insurer's definition of 'partner' when you apply.
Can we have different levels of cover on a joint policy?
Usually the core cover is the same for everyone on the policy, though some modular policies let you vary options such as dental or therapies per person. If you want very different cover, two separate policies may suit you better.
Does my partner's claim affect my premium?
It can. On policies with a shared no-claims discount, a claim by either partner can raise the renewal price for both. Some insurers, such as Aviva, give each person their own no-claims discount, so one partner's claim doesn't affect the other's.
What happens to a joint policy if we separate?
Insurers will normally split the policy so each person can continue on their own, usually keeping their existing underwriting terms so neither of you loses cover you've built up. Contact the insurer as soon as you can to arrange it.
Are we underwritten together or separately?
Separately. Each partner's medical history is assessed individually, so a pre-existing condition that one of you has only affects that person's cover.
