Over 600,000 undocumented immigrants in the UK face systemic barriers to life-saving vaccinations, screenings and routine health checks. This article examines legal entitlements, practical access pathways and community support networks to ensure preventative care reaches every individual regardless of immigration status.
You will learn:
By mapping entitlements to actionable steps, this guide empowers undocumented migrants, healthcare practitioners and advocates to deliver and access essential preventative care today.
Undocumented immigrants are legally entitled to free primary care, including GP consultations and referrals, irrespective of residence status. This entitlement exists because the NHS Act 2006 and NHS Regulations on Charges to Overseas Visitors 2015 define primary care and infectious disease treatment as charge-exempt healthcare services, reducing public health risks and emergency pressures. These rights form the foundation for accessing further preventative interventions such as immunisations and routine screenings.
Even when seeking secondary care, undocumented migrants receive free emergency treatment, maternity services and infectious disease care without upfront charges. Patient confidentiality regarding immigration status is protected by NHS guidelines and data-sharing restrictions, ensuring no routine transfer of personal details to immigration authorities. Understanding these entitlements is critical for building trust and encouraging early engagement with healthcare services.
Improving General Practitioner Registration and Access for Migrant Health in the UK
Migrants in the UK—including refugees, asylum seekers, and undocumented migrants—experience health inequities due to social exclusion, discrimination, language barriers, and, for some, restricted entitlement to healthcare owing to their immigration status.1 In this article, we echo recent calls for more inclusive migrant healthcare2 and consider the impacts of COVID-19 on access to primary care for undocumented migrants in particular. A recent report estimated that there are 674,000 undocumented migrants across the UK, with 397,000 in London.3 The number of undocumented children in the UK increased by 79% between 2011 and 2017, and almost half were born in the UK.3 Home Office statistics show that, every year, approximately 30,000 asylum applications are lodged, and roughly 20,000 of these are granted asylum, alternative forms of leave, or resettlement.4 These figures indicate that there are many migrants who do not have secure immigration status, the right to work, or access to welfare services, leaving them with inadequate housing and potential destitution. These vulnerable situations make it difficult for migrants to access the healthcare services they require, despite many having additional healthcare needs (see Box 1).
Improving GP registration and access for migrant health, DN Blane, 2022
The NHS provides four core charge-exempt services to all UK residents regardless of status:
These services remove cost barriers and safeguard public health by preventing outbreaks of infectious disease and ensuring maternal and child health.
GP registration is a right under NHS policy and does not legally require proof of address or identification. In practice, many practices will accept:
Presenting any informal proof triggers registration rather than denial, allowing access to ongoing preventative services.
Undocumented migrants are entitled to:
These exemptions reduce long-term costs by preventing complications and safeguard the health of mothers and newborns.
NHS regulations prohibit routine data-sharing with immigration enforcement. Healthcare providers record only necessary medical information, and any request for personal immigration data must be refused according to the NHS confidentiality code. This confidentiality assurance encourages migrants to seek preventative care without fear of deportation.
Essential preventative care encompasses immunisations, disease screenings, reproductive health services and mental health support. These services reduce the burden of late-stage disease treatment, improve quality of life and lower public health costs by intercepting conditions early. Undocumented migrants can access the UK immunisation schedule through community clinics and GP practices as part of routine public health measures.
Community health centres and NGOs also host vaccination drives and mobile clinics, ensuring adult and childhood immunisations remain up to date. Sexual health clinics offer free contraception, STI testing and counselling without charge. Trauma-informed mental health services are available through specialised charities, addressing stress, anxiety and post-migration trauma to bolster overall wellbeing.

This service matrix highlights readily accessible interventions that underpin healthier communities and prepare the ground for overcoming barriers to care.
Early immunisation guards against measles, whooping cough and meningitis, directly reducing preventable illness in vulnerable populations.
Cancer and diabetes screenings are offered free to eligible age groups. Migrants can book:
These diagnostic procedures detect conditions early, enabling timely treatment and improved long-term outcomes.
Confidential, walk-in clinics minimize administrative hurdles and ensure reproductive rights are upheld.
Early mental health interventions enhance resilience, decreasing crisis interventions and improving community integration.
Fear of deportation, perceived NHS debt and complex paperwork deter many undocumented migrants from seeking early care. This psychological barrier often results in reliance on emergency services, elevating costs and risk. Cultural stigma around mental health, lack of translation support and limited awareness of entitlements further compound access challenges, undermining preventative care uptake.
Addressing language and cultural differences requires trained interpreters and culturally sensitive materials. Community clinics and NGOs play a vital role by offering tailored outreach, health education and assistance with GP registration. Practical steps—such as providing informal proof of residence and simplifying appointment booking—significantly reduce friction and build trust in the healthcare system.
Fear of being reported to immigration authorities and the misconception of large NHS bills cause many migrants to delay or avoid appointments. Clear messaging on NHS confidentiality and charge exemptions is essential to rebuild confidence and encourage timely preventative visits.
Limited English proficiency and cultural misunderstandings can lead to misdiagnosis, non-adherence and frustration. Access to professional interpreters, translated materials and culturally competent healthcare workers helps bridge communication gaps and improves service uptake.
Local community clinics, migrant health projects and NGOs such as Doctors of the World offer free drop-in services for health checks, advice and vaccination clinics. Outreach teams often liaise directly with local populations to provide mobile services in trusted venues like community centres.
These simple tactics unlock primary care access, enabling full participation in preventative programmes.
UK healthcare policy varies regionally, affecting charge-exempt services and entitlements. In England, secondary care remains chargeable for refused asylum seekers, while Scotland, Wales and Northern Ireland extend free primary and secondary care to all refused applicants. Understanding these distinctions is critical for advocates and migrants navigating local systems.
NHS Regulations on Charges to Overseas Visitors 2015 exempt:
Secondary care charges apply to non-exempt migrants in England unless regional devolved policies state otherwise.

These policy variations shape local preventative care availability and influence health equity.
Inclusive access reduces disease transmission, prevents expensive emergency admissions and supports healthier workforce participation. Cost–benefit studies indicate that universal vaccination programmes and regular screenings save the NHS up to four times their initial investment, underscoring the economic rationale for equitable policy.
Advocacy strategies include:
Sustained advocacy drives policy evolution and broadens preventative care inclusion.
Several charities and advocacy groups specialise in delivering preventative services and health navigation assistance. These organisations build trust within migrant communities, provide cultural mediation and conduct outreach vaccination clinics. Their expertise ensures continuity of care and amplifies migrant health equity across the UK.
