Flu jab 2026: who gets it free and where to book

If you’re eligible for a free NHS flu vaccine this autumn, now is the time to understand where you can get it and what to expect. The NHS offers free flu vaccination to millions of people, and eligibility extends beyond simply being over a certain age.

Who is eligible for a free NHS flu vaccine

You can receive a free NHS flu vaccine if you are aged 65 or over. This includes anyone who will reach 65 by 31 March 2027. If you’re aged 18 to 64, you may qualify if you have certain long-term health conditions, are pregnant, live in a care home, work as a frontline health or social care professional, are a main carer for an older or disabled person, or receive carer’s allowance. The eligibility list for those aged 18–64 also includes people who are experiencing homelessness or staying in a homeless hostel or night shelter.

Health conditions that make you eligible include respiratory diseases (asthma, COPD, cystic fibrosis), heart disease, chronic kidney disease, liver disease, neurological conditions (such as Parkinson’s disease, multiple sclerosis, or cerebral palsy), diabetes of any type, a weakened immune system, conditions affecting the spleen, and learning disabilities. Additionally, those with a BMI of 40 or above qualify for a free vaccine.

If you live with someone who has a weakened immune system, you are eligible for the vaccine too, even if you don’t fall into any other category. The logic is that vaccinating people around an immunocompromised person reduces their risk of catching flu.

Where to get the flu vaccine

You have several options for receiving a free NHS flu vaccine. GP surgeries are offering appointments from 1 October 2026 onwards. If you are pregnant, you can book from 1 September 2026. Many NHS pharmacies also offer flu vaccines for adults aged 18 and over, which is often faster than booking a GP appointment—you can walk into a pharmacy and be vaccinated on the same day at many locations.

If you live in a care home, vaccination is typically arranged by the care home itself. Pregnant individuals can also receive the vaccine through maternity services. If you work in health or social care, your employer may offer mass vaccination sessions. You can book online or through the NHS App if you’re eligible; many areas also allow telephone bookings if you prefer not to use digital services.

Pharmacies offering free flu vaccines are easily found by searching online or by ringing your local pharmacy to ask whether they’re offering the service. Check with your GP if you have questions about eligibility or which vaccine is right for you, particularly if you have a condition requiring medical advice.

Vaccine timing and autumn 2026

Flu typically circulates from November through February in the UK, with peak transmission usually between December and January. The NHS recommends being vaccinated by the end of October to ensure you have full protection before the peak season. You can be vaccinated earlier if you prefer, and appointments are available from October 1 (or September 1 for pregnant individuals). Do not wait until December or January, as it takes about two weeks after the jab for immunity to build.

If you have a specific health condition or question about timing—for example, if you are having surgery or another vaccine—discuss it with your GP or the pharmacist when you book.

Combining the flu vaccine with COVID and RSV vaccines

If you’re eligible for multiple vaccines, you can receive the flu vaccine, COVID-19 vaccine, and RSV vaccine (if eligible) at the same appointment. They can be given together without any safety concerns. You do not need to space them out; having them together is safe and convenient.

If you are pregnant, you can receive the flu vaccine at the same time as the whooping cough (pertussis) vaccine and other pregnancy vaccines, though timing depends on your circumstances. Discuss options with your midwife.

What to expect after the flu jab: normal and concerning symptoms

Most people experience no side effects from the flu vaccine or only mild reactions that resolve within a few days. Common, normal reactions include arm soreness or redness where the needle went in, mild fever or chills, a slight headache, or general tiredness. These symptoms typically last one to two days and indicate your immune system is responding to the vaccine.

Taking paracetamol or ibuprofen can help with aches or fever if you find them uncomfortable. Keep the injected arm moving gently—you don’t need to immobilise it.

Serious side effects are very rare. Contact your GP or call 111 if you experience signs of an allergic reaction (rash, breathing difficulty, swelling of the face or throat) within hours of vaccination, or if you develop a high fever that doesn’t respond to paracetamol, severe headache, stiff neck, or confusion. Guillain-Barré Syndrome, a very rare nerve disorder, occurs in fewer than one in a million vaccinated people and typically begins within weeks of vaccination; signs include weakness or tingling that spreads from the legs upward. This is a medical emergency requiring urgent hospital care.

The benefits of flu vaccination far outweigh the risks. Flu itself can cause pneumonia, hospitalisation, and death in older people and those with chronic conditions.
