Children’s Health Insurance: A Practical UK Guide

Adding children to a private health insurance policy gives them faster access to specialist consultants, diagnostics and elective surgery, particularly useful for conditions like ENT, orthopaedic and ophthalmology issues where NHS waits can be long. Children are usually the cheapest people to insure: they’re young, healthy on average, and many insurers offer flat child rates.

This page covers what’s covered, what isn’t, and how to decide whether to add the kids to your policy.

How children’s PMI works

Children are added as dependents on a family policy held by one or both parents. Common pricing models:

• Single child rate; one premium covers all children, regardless of number
• Per-child rate; typically £15-£35 a month per child
• Free children; a few insurers (notably Vitality at certain points) offer no-charge child cover up to a certain age

Cover normally lasts until the child turns 18, 21, or 24 (the higher ages if in full-time education).

What children’s PMI typically covers

Most family policies provide the same core benefits for children as for adults:

• Outpatient consultations with paediatricians and specialists
• Diagnostics; MRI, CT, ultrasound, blood tests
• Inpatient and day-case surgery, often with a parent allowed to stay overnight
• Cancer treatment under the same generous terms as adults
• Outpatient mental health, typically with a session limit
• Physiotherapy and other therapies (depending on tier)

For common childhood specialties; grommets, tonsils, adenoids, hernias, fracture follow-ups, allergy testing; private routes can be substantially faster than the NHS.

What’s not covered

The same broad exclusions apply to children as to adults:

• Routine GP appointments (use NHS GP or a virtual GP service if included)
• Pre-existing conditions diagnosed before the policy started
• A&E and emergency care (always NHS)
• Vaccinations and routine well-child checks
• Most congenital conditions present from birth (varies by insurer)

The congenital condition rule is worth a separate note: insurers vary in how they handle conditions present from birth that are diagnosed after the policy starts. Some cover them; some exclude them. Worth checking the wording before you buy if this is a concern.

When children’s cover is most worthwhile

A few situations make a strong case:

• Recurring ENT issues; grommets, tonsils, adenoids, glue ear are very common in young children. Private routes are typically weeks rather than months.
• Orthopaedic concerns; sports-related injuries, growing pains, suspected hip issues
• Ongoing diagnostic uncertainty; you’ve been waiting for a paediatrician appointment and want a faster opinion
• Travel-prone families; international cover for children is often available as an upgrade
• You already have parental cover; adding children is usually low marginal cost

When you might skip child cover

• Your children are already healthy and the NHS is meeting their needs reasonably
• Budget is tight and adult cover is the priority
• Your employer scheme already covers them at lower cost
• You’d prefer to self-pay for the occasional private GP appointment

Costs in 2026

Adding two children to a family policy typically costs an extra £30-£70 a month in total, depending on insurer and plan. Single-child rates often look like value-for-money if you have three or more children.

Underwriting for children

Children are underwritten the same way as adults; usually Full Medical Underwriting or Moratorium. For young children with no medical history, both routes are usually equivalent in practice. For children with existing conditions (asthma, allergies, eczema), FMU gives clear written confirmation of what’s accepted and excluded.

Switching while children are on the policy

Continued Personal Medical Exclusions (CPME) work for children too. If you switch insurer, your children’s accepted conditions transfer with them. Their NCD typically continues if they haven’t claimed.

What happens at 18 (or 21, or 24)

When children age out of the family policy, most insurers offer a continuation option; they can take out their own individual policy without new underwriting, keeping the conditions accepted under the family policy. This can be a quiet but valuable benefit, especially for young adults with chronic conditions, because it locks in clean underwriting from childhood.

Mental health for children

Children’s mental health waiting lists on the NHS (CAMHS) are among the longest in the system. PMI cover for children’s mental health varies considerably between insurers; session limits, age limits, and the types of therapy covered all differ. If this is a priority, ask specifically what each insurer covers for under-18s.

Frequently asked questions

Is children’s health insurance worth it in the UK? For families who’d otherwise wait many months for routine paediatric specialties (ENT, orthopaedics, allergy), often yes. For families whose children are healthy and the NHS local provision is good, the case is weaker.

Can I insure just my children, not the adults? A few insurers offer child-only policies, though it’s much more common to add children to a parent’s policy.

Does children’s health insurance cover dental and orthodontics? Routine dental isn’t covered by PMI. Some insurers offer a dental add-on, but orthodontics is usually self-pay.

Are vaccinations covered? Routine childhood vaccinations are not covered; they’re free on the NHS. Travel vaccinations are usually self-pay.

What if my child has a long-term condition like asthma? Asthma is usually treated as a pre-existing or chronic condition and excluded. The child can still claim for unrelated new conditions.
