A cough is one of the most common reasons people see a GP, and one of the hardest to judge on your own. Is it the tail end of a cold, a chest infection that needs treatment, or something that has been going on for too long to ignore? If you are coughing up discoloured phlegm, feeling breathless, running a temperature, or simply cannot shake a cough that has lasted weeks, the sensible step is to be examined.
At Wimbledon Medical Service, our private GP team offers same-day appointments for chest infections, bronchitis and persistent coughs at our Wimbledon Village clinic. We listen to your chest, check your oxygen levels, arrange a chest X-ray the same day where it is needed, and tell you plainly what is going on and how to treat it.
Understanding Chest Infections
A chest infection is an infection of the lungs or the airways leading to them. The two main types are:
Acute bronchitis: infection of the large airways (the bronchi), usually viral, which causes a chesty cough that can last three to four weeks
Pneumonia: infection deep in the lung tissue, more often bacterial, which tends to make you feel much more unwell and can be serious, particularly in older adults and people with long-term conditions
Not every cough is an infection. A cough lasting more than eight weeks is classed as chronic, and the common causes include asthma, post-nasal drip from sinus problems or allergies, acid reflux, and certain blood pressure medications. Finding the cause is what makes treatment work.
Symptoms We Can Help With
Chest infection symptoms
A persistent chesty cough, coughing up yellow, green or brown phlegm, wheezing or breathlessness, a high temperature, chest discomfort or pain when breathing, a rapid heartbeat, aching muscles and feeling exhausted.
Persistent cough symptoms
A dry or tickly cough lasting more than three weeks, a cough that is worse at night or first thing in the morning, a cough triggered by exercise, cold air or lying down, or a cough that lingers for weeks after every cold.
Signs it may be something more
Coughing up blood, severe or worsening breathlessness, chest pain, a cough lasting more than three weeks with no obvious cause, unexplained weight loss, night sweats, or a hoarse voice that does not recover. These need prompt assessment and usually a chest X-ray, in line with NHS guidance on coughs.
Common Causes and Risk Factors
Most chest infections follow a cold or flu and are caused by viruses; bacterial infections are less common but more likely to cause pneumonia. They spread through coughs and sneezes, which is why they peak through the winter months.
You are at higher risk of a chest infection, and of it becoming serious, if you are over 65, smoke or vape, have asthma, COPD, diabetes, heart disease or a weakened immune system, or are pregnant. People in these groups benefit most from being seen early rather than waiting to see whether a cough settles.
How We Diagnose Chest Infections and Coughs
Diagnosis starts with a thorough examination. During your private GP consultation, your GP will take a detailed history of your cough and any other symptoms, listen to your chest, and check your temperature, heart rate, breathing rate and oxygen levels. Following NICE guidance, we distinguish bronchitis from pneumonia and judge whether antibiotics will help.
Where further investigation is needed, we can arrange:
Chest X-ray referral: through a trusted local imaging provider, for suspected pneumonia or a cough lasting more than three weeks
On-site blood tests: to look for infection and inflammation markers, with most results back within 24 to 48 hours
Sputum sample: sent for culture when an infection keeps returning or is not responding to treatment
Peak flow and spirometry referral: to check for asthma or COPD behind a chronic cough
Respiratory referral: to a chest specialist for persistent, unexplained or recurrent symptoms, with a referral letter prepared promptly
Treatment Options at Wimbledon Medical Service
Treatment depends on the cause we find:
Honest advice and symptom relief: for viral bronchitis, the most effective way to recover, including rest, fluids, pain relief and guidance on what will and will not help a cough
Antibiotics where they are needed: for bacterial chest infections and pneumonia, prescribed responsibly and issued as a private prescription at your appointment
Inhalers and steroid treatment: for wheeze, asthma flare-ups or an airway that has become inflamed after infection
Treatment of the underlying cause: for a chronic cough, this may mean managing reflux, treating post-nasal drip, reviewing medications or starting asthma treatment
Fit notes and medical letters: including private fit notes when you are too unwell to work
Planned follow-up: a review appointment so that a cough that should have settled is checked rather than left, with onward referral if needed
If you seem to pick up every chest infection going, a broader private health check can look for underlying reasons. Standard 20-minute consultations start from £110, and you can book an appointment online in minutes.
When to See a GP About a Cough or Chest Infection
See a GP if your cough has lasted more than three weeks, you are coughing up discoloured phlegm, you feel breathless or wheezy, you have chest pain, or your symptoms are getting worse rather than better. See us promptly if you are over 65, pregnant, or have asthma, COPD, diabetes or heart disease and develop chest infection symptoms, as early treatment matters most for you.
Call 999 or go to A&E for severe breathlessness, blue lips, chest pain, coughing up blood, or confusion or drowsiness. These can be signs of pneumonia or another serious problem and need emergency care.
If you are unsure whether your symptoms need attention, contact our reception team and we will advise; same-day appointments are usually available.

Frequently Asked Questions
How do I know if I have a chest infection?
A chest infection usually brings a chesty cough with yellow, green or brown phlegm, wheezing or breathlessness, a high temperature and chest discomfort, often following a cold. A GP can confirm it by listening to your chest and checking your oxygen levels, and can tell bronchitis apart from pneumonia.
Do I need antibiotics for a chest infection?
Often not. Most chest infections are viral bronchitis, which antibiotics do not help. Antibiotics are needed for bacterial infections and pneumonia, or for people at higher risk of complications. Your GP will decide based on examination, your oxygen levels and, where needed, a chest X-ray.
When should I worry about a cough?
See a GP if a cough lasts more than three weeks, comes with breathlessness, wheeze or chest pain, or you cough up blood or discoloured phlegm. A cough lasting more than eight weeks is classed as chronic and needs investigation to find the cause.
How long does a chest infection last?
Bronchitis usually clears within three to four weeks, although the cough can linger. Pneumonia takes longer, and tiredness can last for weeks after treatment. If you are not clearly improving after a week, or feel worse, see a GP for review.
Can a private GP arrange a chest X-ray in Wimbledon?
Yes. If your examination suggests pneumonia, or your cough has lasted more than three weeks, your GP will refer you to a trusted local imaging provider, usually the same day, and review the result with you at a follow-up appointment.
Why do I keep getting chest infections?
Repeated chest infections can be linked to smoking, asthma, COPD, acid reflux, a weakened immune system or an underlying lung problem. A GP can examine you, arrange blood tests, breathing tests or a chest X-ray, and put a plan in place to reduce how often they return.
Can I get a sick note for a chest infection?
Yes. If illness keeps you off work, your GP can issue a private fit note at your appointment, whether you are seen in clinic or by video.
How much does an appointment cost?
Standard 20-minute consultations start from £110, with longer appointments available for complex or long-standing problems. Blood tests, some prescriptions and referral letters are charged separately; see our services and fees for details.
Don't Wait for a Cough to Sort Itself Out
Most coughs pass. The ones that do not deserve a proper examination, not another week of waiting. Book a same-day appointment with a private GP at Wimbledon Medical Service, or call our reception team on 020 8153 4239.
