Family health insurance UK

Family health insurance in the UK covers eligible private treatment for adults and children under one policy. Children can join existing cover under the insurer’s rules. Check each child’s start date, terms and benefits.

How a family policy works

A family policy brings everyone insured under one plan. It covers eligible treatment for acute conditions that start after each person’s cover begins. These are illnesses or injuries where treatment aims to lead to recovery.

A shared policy makes paperwork easier to manage. It does not give everyone identical terms. Underwriting can leave each person with different exclusions, even with the same level of cover.

Check who qualifies as an eligible family member under the policy. Rules on children’s ages and dependency vary. If your household has different living arrangements, check these against the insurer’s eligibility rules before applying.

You do not have to move everyone to a new policy to cover a child. Check existing work or private cover first. MoneyHelper’s guide to private health insurance explains what cover is for.

Adding children to your health insurance

Ask whether eligible children can join your existing policy, including during the policy year. Confirm when they are allowed to join and each child’s cover start date.

Adding a child can change the cost. Check their underwriting terms too. The insurer sets these for the child, so do not assume they match those of adults who have held cover longer.

Check the effect on your renewal date and whether the child’s benefits follow the same policy year. Read the child’s policy documents for their benefits and exclusions before agreeing to add them. An adult’s joining date is not the child’s cover start date.

Adding a newborn

There may be a deadline for notifying the insurer about a newborn. The timing affects the terms available, so check the joining rules before the birth if you are planning ahead.

Confirm whether you must formally add the baby to the policy, when their cover starts and how underwriting applies to them. Special newborn provisions depend on the policy wording. Family policies do not all work the same way.

A listed hospital does not always provide the care your child needs.

What family health insurance can cover

Core cover is in-patient and day-patient treatment. In-patient care means a hospital stay. Day-patient care means admission without staying overnight. Core benefits include operations, consultant fees, tests and nursing during an admission. Treatment must meet the insurer’s eligibility rules.

Outpatient cover

Outpatient benefits pay towards eligible specialist consultations and investigations without a hospital admission. Check how consultations and diagnostic tests are covered, including any limits and whether both share a limit.

A policy focused on hospital treatment may leave some appointments or tests outside cover. The guide to outpatient cover explains how these benefits work.

Other benefits depend on the plan. Check the following.

• Therapies such as physiotherapy, including referral requirements.
• Mental health benefits and any age restrictions.
• Cancer cover and the treatment included.
• Dental or optical add-ons and their limits.

Check whether benefit limits apply to each person or are shared across your family. Check when they reset too. Those rules show how much cover is available if several family members need treatment in the same policy year.

Check that each benefit is available to children as well as adults. A benefit’s name does not tell you which care is included. Read treatment rules and limits for each person.

What is usually left out

Most policies exclude pre-existing conditions, for children as well as adults. Buying cover after a problem starts does not make treatment for that problem eligible.

Policies also exclude ongoing management of chronic conditions. These are long-term conditions needing continuing care or monitoring. Routine pregnancy, childbirth and cosmetic treatment are excluded too.

Underwriting sets the terms for pre-existing conditions. Moratorium and full medical underwriting work differently. Neither promises cover for an existing condition.

The specialist can explain how underwriting affects each person joining. The guide to pre-existing conditions and underwriting explains the main approaches.

Read general exclusions alongside each person’s terms. A benefit does not override an exclusion. Check waiting periods too. Not every benefit is available as soon as cover starts.

How costs and excesses work

Cost depends on who is covered, their ages, where they live and the cover chosen. Underwriting also affects the terms available.

Broader benefits can increase cost. The hospital list and outpatient cover also affect your quote. Compare benefits closely so you know what changed between the options.

Compare quotes for the same people and intended start date. Check differences in cover and excess. A lower quote may mean fewer hospitals or less outpatient cover, changing what your family is covered for.

An excess is the amount you agree to pay towards eligible claims under the policy’s rules. A higher excess can reduce the cost of cover but leaves you paying more when it applies.

Check whether the excess applies separately to each person and how often it applies. Treatment for several family members means separate payments if the policy sets an excess for each person.

Choose an excess your household is able to manage if several family members need care. The guide to health insurance excesses explains what to check. Review affordability at renewal, as the cost of keeping cover can change.

Choosing hospitals for children

A hospital list sets out where eligible treatment takes place under the policy. Check the hospitals you could reach, including their arrangements for treating children.

A listed hospital does not necessarily treat children of every age. Check access to suitable children’s specialists and whether the service accepts your child’s age group.

For an admission, check cover for a parent’s accommodation when staying with a child. Read any conditions and limits attached to that benefit. This practical detail matters when comparing family cover.

The nearest listed hospital may lack the service your child needs. Check where eligible children’s care takes place before choosing a hospital list. Consider travel as well as cover.

Using private cover alongside the NHS

Your family can keep using the NHS while holding private cover. NHS care stays free. The policy pays for care that meets its terms. It does not replace every part of NHS care.

Emergency care is excluded. Use NHS emergency services when needed without waiting for an insurance decision. The NHS guide to urgent and emergency care explains the services available.

Check the claims process before booking planned private treatment. A referral may be needed, and some insurers require approval first. Confirm cover for the proposed care, including the hospital and specialist involved.

Approval for an appointment does not necessarily cover later tests or treatment. Check again when further care is proposed. Keep the insurer’s confirmation of what was agreed.

Checking cover as your family changes

Review your child’s cover before they reach the policy’s age limit. Eligibility may depend on education or dependency as well as age. Check options for continuing cover before your child’s eligibility ends. If your child starts a separate policy, confirm its underwriting terms. Do not assume the terms from your family policy carry over.

Check who your work policy covers before buying another. Leaving a job can affect dependants’ cover too. Confirm the end date and continuation options.

When switching insurers, check new terms for everyone. Existing exclusions may continue. Different underwriting affects future claims. Keep current cover until replacement terms and the start date are confirmed.

To compare private health insurance, answer a few questions. The form asks nothing about your health. A health insurance specialist will contact you by phone or email to give quotes and explain family cover, including adding children.
