Flu Vaccines in the UK: Everything You Need to Know for 2026

A complete 2026 guide to NHS flu vaccine eligibility, the main vaccine types used in the UK and private vaccination options for individuals and employers.

As winter approaches each year, flu becomes part of the national health conversation again. It can affect schools, workplaces, care settings, households and wider public services across the UK, which is why vaccination remains an important part of seasonal health planning.

For some people, access to flu vaccination is straightforward. They may be offered a free flu vaccine through the NHS because of their age, health, pregnancy, caring responsibilities or other eligibility criteria. For others, especially many healthy working-age adults, access can be less clear. They may not qualify for a free NHS flu jab, but may still want to reduce their risk of flu or arrange vaccination through a private pharmacy, healthcare provider or employer-led programme.

This guide explains how flu vaccination works in the UK, who is usually eligible for a free NHS flu jab, what vaccine types are used and what private options are available for people outside the national programme. It also looks at how employers can support staff who are not covered by NHS eligibility, including through workplace clinics and flu vaccination vouchers.

Why Flu Vaccination Changes Each Year

Flu is not the same every winter. The strains most likely to circulate can change from season to season, which is why flu vaccines are reviewed and updated each year.

For the 2026 to 2027 flu season in England, the GOV.UK national flu immunisation programme letter states that flu vaccines will be updated in line with World Health Organization recommendations for the Northern Hemisphere. The letter also says that the Joint Committee on Vaccination and Immunisation reviews the latest evidence each year and advises on the vaccine types offered to different age groups.

This is why flu vaccination is planned as an annual programme rather than a one-time vaccine.

Who Can Get A Free NHS Flu Vaccine?

Free NHS flu vaccination is usually offered to people who are at higher risk of serious illness from flu or those who may pass flu on to vulnerable people.

The NHS flu vaccine guidance explains who can usually get the free NHS flu vaccine. This includes people aged 65 and over, pregnant women, people with certain long-term health conditions, care home residents, carers and people who live with someone with a weakened immune system.

Eligibility and delivery can vary across the UK. For Scotland, NHS Inform provides flu vaccine guidance, including separate information on the child flu vaccine.

What About People Who Are Not Eligible For A Free NHS Flu Jab?

Many healthy working-age adults are not eligible for a free NHS flu vaccine. If they want to be vaccinated, they can usually arrange this privately through a pharmacy, private healthcare provider or employer-led workplace vaccination programme.

For individuals, this usually means checking with a local pharmacy or private provider. For employers, it means deciding whether to offer staff vaccination through an on-site clinic, flu vaccination vouchers or a combination of both.

For employers, this is an important gap. A team may include some people who are eligible for a free NHS flu jab and many others who are not. Private workplace flu vaccination can help employers make vaccination available to a wider group of staff, especially in workplaces where seasonal illness can affect staffing, service delivery or business continuity.

When Does Flu Vaccination Usually Start?

Timing matters because flu vaccine protection can reduce over time. For the 2026 to 2027 programme in England, the adult programme continues to start on 1 October. The national flu programme letter says this is because it is preferable to vaccinate adults closer to the time when flu is likely to circulate, with flu typically peaking in December or January.

There are exceptions. Pregnant women and children’s flu vaccination programmes can start from 1 September. The letter also says that most vaccinations for eligible adults, eligible children and frontline health and social care workers should be completed by the end of November, although vaccination can still be offered after that and up to 31 March in some cases.

For employers planning private workplace flu vaccination, this means preparation should start well before autumn. On-site clinic dates are usually booked ahead of the season, and early planning helps organisations secure preferred dates.

Which Flu Vaccine Is Recommended For Each Group In 2026 To 2027?

Different flu vaccines are recommended for different age and risk groups. Some groups have several suitable options, while others have a preferred vaccine. The table below summarises the recommendations in the UKHSA guidance for the 2026 to 2027 NHS flu vaccination programme in England.

What Types Of Flu Vaccines Are Used In The UK?

The descriptions below explain what each vaccine type is and who it is generally used for. The abbreviations follow current UKHSA terminology. The UKHSA marketed-vaccine list confirms that all flu vaccines marketed in the UK for the 2026 to 2027 season are trivalent.

Which Flu Vaccine Is Recommended During Pregnancy?

What Flu Vaccine Do Healthy Working-Age Adults Receive?

Many healthy adults under 65 are outside the free NHS flu programme, but they can still choose private vaccination or receive it through an employer. More than one licensed vaccine may be suitable. The exact vaccine offered depends on age, medical history, the product licence, clinical assessment and the vaccine stocked by the provider.

Doctorcall’s workplace flu vaccination options for 2026 include TIVe, an egg-cultured inactivated vaccine, and TIVr, a recombinant inactivated vaccine. The vaccination team selects the option that fits the employee and the clinic arrangements, following the relevant product information and clinical assessment.

COVID-19 Vaccination And Winter Protection In 2026

Flu is not the only respiratory illness that can cause pressure during autumn and winter. COVID-19 continues to be part of the UK’s seasonal vaccination planning, especially for people at higher risk of serious illness.

COVID-19 vaccine eligibility is more limited than flu eligibility. The NHS COVID-19 vaccine guidance explains who may be offered COVID-19 vaccination and how eligible people can access it.

For the spring 2026 NHS COVID-19 vaccination programme in England, eligible groups include people aged 75 and over, people aged 6 months to 74 years who have a weakened immune system because of a health condition or treatment, and residents in care homes for older adults. The JCVI statement on COVID-19 vaccination in autumn 2026 and spring 2027 sets out advice for the next seasonal programmes.

COVID-19 vaccine products can change by season, as vaccines are updated to match current variants more closely. UKHSA’s Green Book chapter on COVID-19 provides detailed vaccine information for healthcare professionals.

For employers, the key point is that flu and COVID-19 vaccination programmes do not always cover the same groups. Some employees may be eligible for one vaccine but not the other. Others may not be eligible for either through the NHS, but may still want to consider private options where available.

Employers may wish to include flu vaccination in a wider winter health plan. This might include workplace flu clinics, flu vaccination vouchers, clear sickness guidance, good ventilation, support for staff who feel unwell and signposting eligible employees to NHS COVID-19 vaccination information.

Doctorcall can support organisations with workplace flu vaccination and, where available for the season, can also offer COVID-19 vaccination to employees during the same on-site clinic.

How Employers Can Support Staff

A good workplace flu vaccination programme is about access, convenience and showing employees that their health is being taken seriously before winter pressures begin.

For many people, getting a flu jab privately means finding a pharmacy, booking an appointment and fitting it around work, commuting, childcare or other responsibilities. When an employer brings vaccination into the workplace, or offers vouchers that staff can use locally, it removes much of that friction. The easier it is to access vaccination, the more likely people are to take it up.

This matters for employers too. Sickness absence remains a significant issue for UK workplaces. The CIPD Health and Wellbeing at Work 2025 report found that average absence had risen to 9.4 days per employee per year, the highest level recorded in more than 15 years. CIPD also reports that employers see wellbeing investment as delivering measurable returns, including reduced sickness absence, improved engagement and better performance.

Flu and other respiratory infections can affect productivity in more than one way. Some employees are absent because they are too unwell to work. Others continue working while ill but are less able to concentrate, communicate or perform at their usual level. A systematic literature review on influenza, influenza-like illness and work productivity found that workplace impact includes both absenteeism and presenteeism, with productivity losses varying across studies and settings.

A workplace flu vaccination programme can help employers make winter health support more practical. It can be especially useful for teams where absence or reduced performance has a direct operational impact, such as education, manufacturing, construction, hospitality, healthcare support, transport and customer-facing roles.

How Doctorcall Supports Workplace Flu Vaccination

Doctorcall supports organisations with workplace flu vaccination through on-site clinics and flu vaccination vouchers. Employers can choose the option that best fits their workforce, whether staff are based in one location, spread across multiple sites, working shifts or working remotely.

On-site clinics make vaccination easy for employees by bringing the service into the workplace. Flu vaccination vouchers offer flexibility for staff who cannot attend a clinic or who are based elsewhere. Many organisations use a mix of both to reach more people.

For employers planning ahead, early booking can help secure preferred autumn clinic dates and gives teams time to prepare staff communications before the winter season.
