The debate around NHS waiting times has become increasingly prominent in the UK, particularly as demand for healthcare services continues to outpace capacity. Among the many factors discussed, immigration is frequently highlighted as a contributing cause. However, public discourse often oversimplifies the issue, failing to reflect the full evidence behind the immigration impact on NHS waiting times.
The UK’s National Health Service operates under sustained pressure due to an ageing population, chronic workforce shortages, and rising rates of long-term illness. Immigration intersects with all of these factors, influencing both the demand for healthcare services and the supply of medical professionals. Understanding the immigration impact on NHS systems requires a balanced, evidence-based approach rather than assumptions or political rhetoric.
Migrants play a significant role in sustaining the NHS workforce. Doctors, nurses, care workers, and allied health professionals from overseas form a vital part of healthcare delivery across England, Scotland, Wales, and Northern Ireland. At the same time, immigration does influence demand for health services. Migrant populations, like the wider UK population, require access to GP services, hospital treatment, maternity care, and mental health support. The benefits migrants bring to public services include helping to address staffing shortages and supporting the sustainability and effectiveness of the NHS.
For policymakers, healthcare planners, and the public, understanding the relationship between immigration and NHS waiting times is essential. This article provides a comprehensive examination of the immigration impact on NHS waiting times, addressing workforce contributions, service demand, health policy, and access to care. The government’s policies and decisions play a key role in shaping immigration impact on NHS waiting times and public services. By exploring these interconnected issues, we aim to replace myths with facts around one of the UK’s most pressing public service challenges.
Immigration System and the NHS Workforce Crisis
One of the most significant yet underappreciated aspects of the immigration impact on NHS waiting times is the role of migrant workers within the healthcare system. The NHS has faced persistent staffing shortages for over a decade, driven by rising demand, insufficient domestic training capacity, and high staff turnover. Immigration has become a critical mechanism for sustaining service delivery and preventing further deterioration in waiting times.
According to the Migration Observatory, international staff are essential to the NHS workforce. A recent analysis found that approximately 21% of NHS staff in England—over 300,000 employees—have a non-British nationality. In London, about 32% of NHS staff are non-British, compared to 13% in the North East and Yorkshire. The NHS is currently facing around 100,000 vacancies for nurses and other roles, making overseas staff critical for addressing workforce shortages.
The UK immigration impact on NHS is primarily shown via recruitment and retention of professionals. Visa routes such as the Health and Care Worker visa have been introduced to attract overseas talent, yet administrative delays, sponsorship requirements, and restrictive eligibility criteria can limit their effectiveness. When recruitment is slowed or retention becomes difficult, the immigration impact on NHS waiting times becomes more pronounced, as understaffed departments struggle to meet patient demand.
In June 2025, 36.3% of doctors and 30% of nurses and health visitors in the NHS reported a non-British nationality. International recruits comprised about 50% of doctors in the NHS in 2022, many of whom were trained outside the UK. Nearly 27 percent of NHS nurses are from outside the UK, and the NHS needs to recruit an additional 5,000 international nurses a year until 2023/24 to maintain its services. Chronic shortages in these sectors increase hospital discharge delays, reduce bed availability, and create bottlenecks across the healthcare system.
However, the immigration health surcharge and visa costs have introduced additional challenges. Migrant NHS workers are required to pay significant fees to access healthcare services, despite contributing through taxation and frontline service delivery. When skilled professionals leave the UK due to immigration-related barriers, the resulting workforce gaps exacerbate the immigration impact on NHS capacity.
Language barriers and uncertainty around immigration status can also affect workforce integration. While many NHS trusts provide support, inconsistent guidance and administrative complexity can limit the full utilisation of migrant staff.
Immigration Impact on NHS Services Demand
Public discussion around NHS waiting times often focuses on demand, with immigration frequently cited as a key pressure point. However, when examined through data and service-use patterns, the immigration impact on NHS demand in the UK as a country is more nuanced than commonly portrayed. The most recent reputable survey estimated the cost of migrants using NHS services as £1.4 billion, which is relatively small compared to the country’s overall NHS budget. Different countries may experience varying impacts of migration on their healthcare systems, depending on national policies and demographics.
For example, studies have shown that many migrants are younger and economically active, meaning their use of NHS services is often lower than the average UK resident, and their tax contributions can help offset costs, as a positive immigration impact on nhs.
What Impact Does Current Immigration Have On The NHS Services Due to Migrant Needs?
Immigrants access NHS services across the same pathways as UK-born residents, including emergency care, GP services, and secondary care. However, numerous studies indicate that immigrants, particularly recent and working-age immigrants, tend to use healthcare services less frequently than the UK-born population. This lower usage is partly because immigrants are generally younger and healthier. This usage pattern is a critical but often overlooked element of the immigration impact on NHS performance.
Key factors influencing migrant healthcare use include:
- Age profile: Migrants are generally younger and healthier than the overall UK population
- Employment status: Higher employment rates reduce reliance on healthcare services
- Initial health selection: Many migrants arrive in good health due to work or study requirements
- Barriers to access: Language, awareness of entitlements, and administrative complexity
Studies have consistently shown that immigrants use health services up to 40% less than UK-born residents.
These factors mean that, despite population growth, immigration impact on NHS does not automatically translate into proportionate increases in NHS service use.
Primary Care and GP Services
GP services are often highlighted as being under pressure due to population increases. While immigration contributes to patient registration growth, the demand impact must be viewed alongside workforce supply. Migrant GPs and practice nurses play a significant role in meeting this demand, helping to offset the pressure created by population changes. In addition to GP services, nurse consultations and other primary care services—such as accident and emergency services, palliative care, and NHS dentistry—are also available. Importantly, GP and nurse consultations in primary care are free at the point of service for all, regardless of immigration status.
From an NHS planning perspective, the immigration impact on NHS primary care is shaped by both sides of the equation:
When workforce planning does not keep pace with population change, waiting times increase regardless of whether growth comes from immigration or natural population ageing.
Secondary Care and Hospital Services
Migrants do use secondary care services, but evidence shows that usage rates remain lower than those of UK-born residents when adjusted for age and health status. Access to secondary care in the UK is residence-based, meaning that people who are not defined as ‘ordinarily resident’ may be required to pay for their care. The table below illustrates typical differences in healthcare utilisation patterns to show immigration impact on NHS demand:
| Factor | Migrant Population | UK-Born Population |
| Average age | Younger | Older |
| Chronic conditions | Lower prevalence | Higher prevalence |
| GP consultation rate | Lower | Higher |
| Emergency admission rate | Lower | Higher |
Diversity and Changing Healthcare Needs
Migrant communities may have specific healthcare requirements linked to maternal health, mental health, or previous experiences of trauma. Communicable diseases are also a key public health consideration in migrant communities, and NHS services provide treatment for certain communicable diseases regardless of immigration status. Addressing these needs effectively can improve outcomes and reduce long-term strain as a result of immigration impact on NHS.
Healthcare professionals increasingly require:
- Cultural competence training
- Access to professional interpreters
- Clear guidance on migrant entitlements
- Collaboration with community organisations
- Comprehensive information and expert guidance on UK work visas
Effective communication improves early diagnosis and treatment, which in turn reduces avoidable emergency admissions. In this way, responsive care delivery can mitigate negative perceptions of the immigration impact on NHS waiting times.
Demand, Planning, and Policy Implications
The immigration impact on NHS demand must be understood within the broader context of demographic change. Population ageing, rising life expectancy, and increasing prevalence of long-term conditions place far greater pressure on the NHS than migration alone. Without adequate workforce expansion and infrastructure investment, waiting times will continue to rise regardless of immigration levels.
Political narratives often exaggerate the negative impact of immigration on NHS, and public outcry is frequently driven by such rhetoric rather than evidence. Policymakers should explore ways to improve NHS accessibility and workforce planning in response to demographic changes, including facilitating international recruitment and providing inclusive healthcare access to support the system’s sustainability.
Health Tourism and Fair Access
The term ‘health tourists’ is often used to describe non-UK residents who travel to the UK primarily to access NHS healthcare. However, the narrative that immigration leads to widespread health tourism is often exaggerated and not supported by substantial evidence. When assessed through evidence and policy analysis, health tourism represents a relatively small component of overall NHS demand. Misunderstanding this issue can distort perceptions of the wider immigration impact on NHS waiting times and divert attention from more significant structural challenges.
The treatment provided to health tourists and migrants varies depending on the type of care. While emergency treatment provided by the NHS is available to all, other services such as primary and secondary care may be billed to non-residents unless exemptions apply. This means that the actual impact of health tourists on NHS resources is limited, as most migrants and visitors do not access the full range of treatment provided free of charge.
Scale of Health Tourism in the NHS
Evidence consistently indicates that health tourism accounts for a very small proportion of expenditure, and acts as a minimal driver of immigration impact on NHS. The costs associated with overseas visitors who are not entitled to free care are minimal when compared to the overall NHS budget and do not meaningfully explain long waiting times.
Key points supported by research include:
- Health tourism represents a fraction of one percent of total NHS spending
- The majority of migrants are net contributors to public finances
- Administrative costs of enforcement can exceed recovered charges
- Emergency care is legally required regardless of immigration status
This context is essential when evaluating the immigration impact on NHS waiting times, as overstating health tourism risks misdirecting policy responses.
Fair Access to NHS Services
Migrants who are lawfully resident in the UK are entitled to access NHS services on the same basis as British citizens, particularly if they have paid the immigration health surcharge. Eligibility for free healthcare under NHS rules generally depends on immigration status and residence requirements; those with indefinite leave to remain, refugees, and certain vulnerable groups are exempt from charges, while short-term visitors and some overseas students may not qualify for free NHS care.
Research indicates that immigration impact on NHS is more in terms of contribution than consumption. Restricting access to primary or preventative care can result in delayed diagnoses, leading to more complex and expensive treatments later. This approach ultimately increases pressure on hospitals and contributes indirectly to longer waiting times.
Barriers Created by Charging and Eligibility Rules
While charging regulations aim to protect NHS resources, they can create unintended barriers, particularly for vulnerable groups. Common barriers include:
- Uncertainty around entitlement to NHS services
- Fear of data sharing with immigration enforcement
- Financial barriers linked to upfront charging
- Lack of clear communication from healthcare providers
In recent years, the UK government has made immigration applications directly linked to access to health services, a policy that is unique among European countries. This means that eligibility for NHS care, payment of the immigration health surcharge, and other requirements are now an integral part of the immigration application process.
When individuals delay seeking care, conditions often worsen, resulting in emergency admissions that place greater strain on NHS capacity. In this way, restrictive access policies can negatively influence the immigration impact on NHS waiting times rather than alleviate it.
Immigration Health Surcharge and NHS Entitlements
The immigration health surcharge (IHS) is a central feature of the UK immigration system and plays a significant role in discussions about fairness, funding, and access to healthcare. Any serious analysis of the immigration impact on NHS waiting times must account for how the surcharge operates and how it affects migrant access to NHS services. Unlike many EU countries and other European countries, where healthcare access for migrants and visitors may be based on reciprocal agreements or different residency requirements, the UK requires most migrants to pay the IHS as part of their visa application. The UK’s approach also differs from some European Economic Area (EEA) countries, which may not impose a similar health surcharge or have alternative systems for healthcare funding and access for overseas visitors.
What Is the Immigration Health Surcharge?
The immigration health surcharge is a mandatory fee paid by most migrants applying for a visa to live, work, or study in the UK for more than six months. The surcharge is paid upfront as part of the visa application process and is intended to support NHS funding. The surcharge must be paid in the same amount per person or dependent, and it has increased to £1,035 per person per year for those required to pay, such as skilled workers and their dependants.
Once paid, the IHS entitles migrants to access NHS services on broadly the same basis as UK residents. This includes both primary and secondary care, subject to standard NHS rules such as GP registration and referral pathways.
From a policy perspective, the surcharge is designed to ensure that migrants contribute financially to the NHS while maintaining universal access to essential healthcare. This is an important but often overlooked aspect of the immigration impact on NHS funding.
Financial Barriers and Access Challenges
Despite its policy intention, the immigration health surcharge can create financial barriers, particularly for low-income migrants, families, and young people. The requirement to pay the surcharge in full, alongside visa fees and legal costs, can place significant strain on household finances. The cost of the surcharge is a substantial consideration for many migrants, directly affecting their ability to access NHS care when needed.
It can discourage timely healthcare access and increases the likelihood of emergency admissions, which are more costly and place additional pressure on NHS services. In this way, restrictive access linked to the surcharge can indirectly worsen the immigration impact on NHS waiting times.
Contribution of the Immigration Health Surcharge to NHS Funding
While the surcharge generates substantial revenue, it represents a relatively small proportion of total NHS funding. Its primary value lies in reinforcing the principle of contribution rather than solving systemic funding challenges.
| Aspect | Immigration Health Surcharge |
| Purpose | Financial contribution to NHS |
| Who pays | Most non-UK visa holders |
| Access granted | Primary and secondary care |
| Share of NHS funding | Limited |
| Impact on waiting times | Indirect |
Asylum Seekers and Social Care
Asylum seekers and refugees represent a particularly important group when examining the immigration impact on NHS waiting times. Ensuring equitable access to healthcare for these populations is both a legal obligation under UK and international law and a practical necessity for maintaining public health and NHS efficiency.
NHS Entitlements for Asylum Seekers and Refugees
Under UK law, asylum seekers and recognised refugees are entitled to access NHS services, including:
- Primary care: GP registration and routine consultations
- Secondary care: Hospital treatment, specialist referrals, and emergency care
- Maternity and paediatric services: Full care for pregnant women and children
- Mental health support: Counselling, therapy, and psychiatric treatment
These NHS entitlements are provided regardless of financial status, reflecting the UK’s commitment to human rights and public health. Ensuring that this access is clear and well-communicated reduces delays in treatment and prevents unnecessary pressure on emergency services, another positive immigration impact on NHS waiting times.
Vulnerable Populations and Specialised Support
Certain groups within the asylum seeker and refugee population require more intensive support due to trauma, exploitation, or abuse. Examples include:
- Survivors of domestic violence
- Victims of human trafficking
- Individuals with pre-existing physical or mental health conditions
Providing specialised care for these groups is essential for both ethical and operational reasons. Delays or gaps in care can lead to deterioration of health, which in turn increases emergency admissions and contributes to immigration impact on NHS waiting times.
Collaboration Between NHS and Social Care Providers
Effective management of healthcare access for asylum seekers and refugees depends on strong collaboration between NHS services, local authorities, and community organisations. Coordination ensures that:
- Appointments are attended and treatment plans followed
- Language and cultural barriers are addressed proactively
- Vulnerable patients receive early interventions to prevent health crises
Data Sharing, Confidentiality, and Impact on NHS Waiting Lists UK
Balancing data sharing and confidentiality is essential for both ethical and operational reasons. By ensuring migrants trust the NHS and understand their rights, the system can deliver care more efficiently, reducing preventable delays. Properly managed, this contributes positively to managing the immigration impact on NHS waiting times.
| Factor | NHS Practice | Effect on Migrants | Impact on Waiting Times |
| Data collection | GP registration and hospital records | Enables accurate monitoring | Supports workforce and resource planning, reducing waiting times |
| Confidentiality | Strict legal protections | Builds trust in healthcare system | Encourages early care, lowering emergency admissions |
| Fear of enforcement | Clear communication and outreach | Increases registration and access | Prevents delayed treatment, indirectly reducing waiting times |
| Public health emergencies | Temporary, secure data sharing | Ensures timely interventions | Helps manage system pressure during crises |
Restricting Access to the NHS for Undocumented Migrants: How Bad Is That?
The issue of NHS access for undocumented migrants is one of the most debated aspects of the immigration impact on NHS waiting times. Restricting care for this population raises complex ethical, legal, and operational questions while potentially exacerbating pressures on healthcare services.
Current Policy on Undocumented Migrants
Undocumented migrants—those without lawful status in the UK—have very limited entitlements under current NHS rules. They are generally:
- Charged for secondary care: Including most hospital treatments
- Required to pay upfront fees: For elective procedures and non-emergency care
- Entitled to free care in emergencies: Accident & emergency treatment, urgent maternity, and treatment for certain communicable diseases (such as tuberculosis and other public health risks) is provided free of charge regardless of immigration status, to help manage communicable disease transmission and protect public health.
These restrictions aim to manage NHS resources and prevent misuse. However, the practical impact on waiting times and overall system efficiency is more complex.
Consequences of Restricted Access
Restricting healthcare access can produce unintended consequences that increase pressure and limit the positive immigration impact on NHS, including:
- Delayed treatment: Conditions that could have been managed in primary care escalate into emergencies
- Higher costs: Emergency treatment is more expensive than preventive care
- Public health risks: Untreated infectious diseases can spread, affecting wider communities
- Inequity: Vulnerable individuals, including children, pregnant women, and victims of abuse, may suffer disproportionately
These consequences demonstrate that denying access may worsen, rather than improve, NHS efficiency and waiting times.
