As an FCA-authorised broker that has helped arrange over 800,000 policies, we at WeCovr know that a child's health is a parent's top priority. This guide demystifies childhood fevers, explaining when to worry and how UK private medical insurance can provide peace of mind and rapid access to care.
Understand childhood fevers, red-flag symptoms, and how PMI supports fast access to paediatric care
A child's sudden fever can send a wave of anxiety through any parent. Is it just a common cold, or something more serious? When should you manage it at home, and when should you seek urgent medical help?
This comprehensive guide is designed to give UK parents the confidence to navigate childhood fevers. We will cover:
- What fever is and why it happens.
- How to care for a feverish child at home.
- The critical 'red-flag' symptoms that require immediate attention.
- How the NHS and private healthcare systems work together.
- The supportive role private medical insurance (PMI) can play in accessing swift, expert paediatric care for non-emergency concerns.
What Exactly Is a Fever in a Child?
A fever isn't an illness in itself; it's a sign that the body's immune system is fighting an infection or illness. Think of it as the body turning up its internal thermostat to create an environment where viruses and bacteria struggle to survive.
A child's normal body temperature is typically around 36.4°C (97.5°F), but this can vary slightly from child to child. According to NHS guidance, a fever in a child is defined as a temperature of 38°C (100.4°F) or higher.
While often caused by common viral infections like colds, flu, or chickenpox, a fever can sometimes signal a more serious bacterial infection, such as a urinary tract infection (UTI), pneumonia, or in rare cases, meningitis. The key is not just the number on the thermometer, but how your child is behaving overall.
How to Take Your Child's Temperature Correctly
Getting an accurate temperature reading is the first step. Gone are the days of old-fashioned mercury thermometers. Today's digital options are faster, safer, and more accurate.
Types of Thermometers for Children:
| Thermometer Type | How it Works | Best For | Pros & Cons |
|---|
| Digital (Underarm) | Placed in the armpit. | All ages | Pro: Safe and easy. Con: Can be less accurate than other methods. |
| In-ear (Tympanic) | Measures infrared heat from the eardrum. | Babies over 6 months | Pro: Very fast (1-3 seconds). Con: Earwax or a curved ear canal can affect the reading. |
| Forehead (Temporal) | Scans the temporal artery on the forehead. | All ages | Pro: Non-invasive, good for sleeping children. Con: Accuracy can be affected by sweat or drafts. |
How to get an accurate reading:
- Read the instructions: Always follow the manufacturer's guide for your specific thermometer.
- Stay calm: Try to take the temperature when your child is calm and still.
- Wait if necessary: If your child has just had a warm bath or been bundled up in blankets, wait a few minutes before taking their temperature to get a true reading.
Managing a Fever at Home: Practical Tips for Parents
For most common childhood illnesses, a fever can be safely managed at home. The goal is to keep your child comfortable while their body fights the infection.
Here’s what you can do:
- Hydration is Key: Offer plenty of fluids to prevent dehydration. Water is best, but you can also offer diluted fruit juice, milk, or even an ice lolly. For babies, continue to offer breast milk or formula.
- Keep Them Comfortable: Dress them in light clothing and use a light sheet or blanket. Don't overdress them or pile on blankets, as this can trap heat. Keep the room at a comfortable, cool temperature.
- Food is Optional: Don't worry if your child doesn't have much of an appetite. As long as they are drinking, they will be fine for a few days. Offer light foods if they seem hungry.
- Medicines (If Needed): You can give your child paracetamol or ibuprofen if they are distressed or seem unwell.
- Paracetamol: Can be given to children over 2 months old.
- Ibuprofen: Can be given to children over 3 months old and weighing more than 5kg.
- Crucially: Always follow the dosage instructions on the packet based on your child's age and weight. Never give both at the same time unless advised by a healthcare professional.
- Never Give Aspirin: Do not give aspirin to children under 16, as it is linked to a rare but serious condition called Reye's syndrome.
The most important thing is to watch your child, not the thermometer. A child with a 39°C fever who is playing and drinking happily is often less concerning than a child with a 38.2°C fever who is lethargic and refusing fluids.
Red-Flag Symptoms: When to Call 999 or Go to A&E
While most fevers are harmless, some are accompanied by symptoms that indicate a serious illness requiring immediate medical attention. Trust your parental instincts. If you are seriously worried, seek help immediately.
Go to the nearest Accident & Emergency (A&E) department or call 999 for an ambulance if your child has a fever AND any of the following symptoms:
Urgent Red Flags for All Children
- Breathing difficulties: Making grunting noises, sucking their tummy in under their ribs, or nostrils flaring.
- A non-blanching rash: A rash that does not fade when you press a clear glass against it. This can be a sign of meningitis.
- Changes in consciousness: Seems unusually drowsy, is difficult to wake up, is confused, or has a weak, high-pitched cry.
- A seizure (fit): This can be a febrile convulsion, which is often scary but usually harmless, but it always needs to be checked out urgently the first time it happens.
- A stiff neck: Cannot put their chin to their chest.
- Pale, mottled, or blue skin, lips, or tongue.
- Is under 3 months old and has a temperature of 38°C or higher.
- Is 3 to 6 months old and has a temperature of 39°C or higher.
- Shows signs of severe dehydration: Sunken eyes, a sunken fontanelle (the soft spot on a baby's head), a dry mouth, or no wet nappies for 12 hours.
This table summarises the most critical signs:
| Symptom Category | Red-Flag Sign | Action Required |
|---|
| Breathing | Grunting, flared nostrils, sucking in ribs | Call 999 / Go to A&E |
| Skin/Rash | Rash that doesn't fade under a glass ("non-blanching") | Call 999 / Go to A&E |
| Consciousness | Drowsy, difficult to wake, confused, stiff neck | Call 999 / Go to A&E |
| Age-Specific | Under 3 months with temp ≥ 38°C | Call 999 / Go to A&E |
| Age-Specific | 3-6 months with temp ≥ 39°C | Call 999 / Go to A&E |
| Hydration | No wet nappy for 12 hours, sunken eyes/fontanelle | Call 999 / Go to A&E |
Private medical insurance is not designed for emergencies. A&E and 999 are the correct and only pathways for urgent, life-threatening situations.
For situations that are concerning but not life-threatening emergencies, your GP or the NHS 111 service is the right port of call.
Contact your GP or call 111 if:
- The fever lasts for more than 5 days.
- Your child has a fever but is still shivering or complaining of feeling cold.
- You are worried and feel your child is getting worse.
- Your child has other signs of illness, such as a persistent sore throat, earache, or pain when weeing.
- Your child has a long-term health condition, such as heart, lung, or kidney disease, which might make them more vulnerable.
- The fever went away for more than 24 hours and then returned.
NHS 111 can provide advice, book an out-of-hours GP appointment, or direct you to the most appropriate service.
How Private Medical Insurance (PMI) Can Help When Your Child is Unwell
While the NHS provides excellent emergency and primary care, accessing specialist services for non-urgent issues can sometimes involve long waits. According to NHS England data, the median waiting time for consultant-led elective care was around 15 weeks in early 2025. This is where private medical insurance UK can be a huge comfort for families.
PMI is designed to work alongside the NHS. It provides funding for prompt diagnosis and treatment of acute conditions – new, short-term illnesses or injuries that are likely to respond quickly to treatment.
Key benefits of PMI for paediatric care include:
- Fast Access to Specialists: If your GP feels your child needs to see a paediatrician, an ENT (Ear, Nose, and Throat) specialist for recurrent tonsillitis, or a dermatologist for a skin condition, PMI can allow you to bypass long NHS waiting lists and see a consultant in days or weeks.
- Digital GP Services: Most modern PMI policies include a 24/7 virtual GP service. For a worried parent at 2 am, being able to speak to a doctor via video call within minutes is invaluable. They can offer reassurance, prescribe medication, and provide an open referral letter for specialist care if needed.
- Choice of Hospital and Consultant: PMI gives you more control over your child's care, allowing you to choose from a list of approved high-quality private hospitals and leading paediatric specialists.
- Comfort and Privacy: Private hospitals typically offer private en-suite rooms, making a hospital stay less stressful for both child and parent.
An expert PMI broker like WeCovr can help you compare policies from the UK's leading insurers to find cover that fits your family's needs and budget, at no cost to you.
Real-Life Example: Recurrent Ear Infections
Imagine your two-year-old suffers from repeated ear infections and fevers. Your NHS GP has prescribed antibiotics several times, but the problem persists. The next step is a referral to an ENT specialist to consider grommets, but the local waiting list is over six months long.
With private health cover, your journey could look like this:
- Step 1: After another sleepless night, you use your insurer's 24/7 virtual GP app.
- Step 2: The private GP agrees that a specialist opinion is needed and provides an open referral letter.
- Step 3: You call your insurer to get the claim pre-authorised.
- Step 4: You book an appointment with a leading paediatric ENT specialist for the following week.
- Step 5: After the consultation, the specialist recommends surgery, which is scheduled for a few weeks later at a convenient private hospital.
This speed and convenience can significantly reduce stress and get your child back to feeling well sooner.
A Critical Note on PMI: Pre-existing and Chronic Conditions
It is vital to understand what private medical insurance does and does not cover. Standard UK PMI policies are designed for acute conditions that arise after you take out the policy.
- Acute Condition: A disease, illness, or injury that is likely to respond quickly to treatment, returning you to the state of health you were in before it started (e.g., a cataract, joint replacement, hernia repair).
- Chronic Condition: A disease, illness, or injury that has one or more of the following characteristics: it needs ongoing or long-term monitoring, has no known cure, is likely to come back, or requires palliative care (e.g., asthma, diabetes, eczema).
PMI does not cover the routine management of chronic conditions. These will continue to be managed by the NHS. Likewise, pre-existing conditions – illnesses your child had before the policy began – will be excluded from cover, either permanently or for a set period.
Finding the Best Private Health Cover for Your Family
Choosing a family policy requires careful thought. Here are the key factors to consider:
- Level of Cover: Policies range from basic (covering only inpatient treatment) to comprehensive (including outpatient consultations, diagnostic scans, and therapies like physiotherapy).
- Outpatient Limits: A common feature is a cap on the value of outpatient services per year (e.g., £500, £1,000, or unlimited). A higher limit means more cover for consultations and tests before any hospital admission.
- Hospital List: Insurers offer different tiers of hospital lists. A national list is standard, but you can pay more to include prime central London hospitals.
- Excess: This is the amount you agree to pay towards the cost of a claim. A higher excess (e.g., £250 or £500) will lower your monthly premium.
- Underwriting:
- Moratorium: The insurer doesn't ask for your medical history upfront. Instead, they will exclude treatment for any condition you've had symptoms of or advice for in the last 5 years. This exclusion is typically lifted if you go 2 continuous years on the policy without needing treatment or advice for that condition.
- Full Medical Underwriting (FMU): You provide your full medical history. The insurer then tells you exactly what is excluded from day one. This provides more certainty but can be more complex.
Here is a simplified comparison of cover levels:
| Feature | Basic "Inpatient Only" Cover | Mid-Range "Core" Cover | Comprehensive Cover |
|---|
| Inpatient/Day-patient Care | ✅ Full Cover | ✅ Full Cover | ✅ Full Cover |
| Cancer Care | ✅ Full Cover | ✅ Full Cover | ✅ Full Cover (often with enhanced options) |
| Virtual GP Access | ✅ Usually included | ✅ Usually included | ✅ Usually included |
| Outpatient Consultations & Tests | ❌ Not included | ✅ Included (often up to a limit, e.g. £1,000) | ✅ Full Cover |
| Physiotherapy & Therapies | ❌ Not included | ❌ Often an add-on | ✅ Included |
| Mental Health Cover | ❌ Not included | ✅ Often included as an add-on or with limits | ✅ More extensive cover |

Frequently Asked Questions about Childhood Fevers and PMI
Can I add my child to my existing private medical insurance policy?
Yes, most insurers allow you to add your newborn or older children to your existing policy, often at your policy renewal date. Some insurers even offer a period of free cover for newborns. It is usually more cost-effective to have one family policy rather than separate policies for each member.
Does PMI cover routine childhood vaccinations?
Generally, no. Routine and preventative treatments, including the standard UK childhood immunisation schedule (e.g., MMR, 6-in-1), are not covered by private medical insurance as they are provided for free by the NHS. PMI is for treating unforeseen acute illness and injury.
What happens if my child's condition, first diagnosed privately, turns out to be chronic?
This is a very important point. Private medical insurance will typically cover the initial diagnosis of a new condition. However, if that condition is then classified as chronic (e.g., asthma, Crohn's disease), the policy will not cover the ongoing, long-term management. At that point, your child's care for that specific condition would seamlessly transition back to the NHS, which is set up to provide excellent long-term chronic care.
Do I still need to be registered with an NHS GP if I have PMI?
Yes, absolutely. It is a requirement of all UK private medical insurance policies that you and your family remain registered with an NHS GP. The two systems are designed to work together. Your NHS GP manages your day-to-day health and chronic conditions, while PMI provides an additional route for faster access to specialist care for acute conditions.
Navigating your child's health can be daunting, but being informed is the best tool a parent can have. Understanding when to act, what to look for, and what your options are provides immense peace of mind.
While the NHS is the cornerstone of UK healthcare, a private medical insurance policy can offer a valuable layer of support, ensuring that for non-emergency issues, your child gets the expert care they need, right when they need it.
