Economic Impact of Removing ILR Migrants Under a Reform UK Government

In this article, I, with the assistance of ChatGTP research mode look at the possible impact on the UK economy Reform UK’s proposed deportation of not just failed asylum seekers, but those on indefinite leave to remain needing to reapply under new requirements.

It is important to understand that this is a forecast based on what we currently know of Reform’s plans should they gain power.

Nigel Farage at a Reform UK press conference. Farage has vowed to leave the ECHR and revoke Indefinite Leave to Remain status for migrants if in power. In this scenario, we assume the Reform UK party (led by Nigel Farage) wins power and rapidly implements its hard-line manifesto promises on immigration. These include withdrawing from the European Convention on Human Rights (ECHR) and abolishing Indefinite Leave to Remain (ILR) status for migrants – effectively forcing many long-term residents to reapply for visas or leave the UK (theguardian.com). Below, we examine the timeline for such policies, estimate the number of migrants who might have to leave, and discuss the impact on the UK economy, including the effect on legal migrants who may voluntarily emigrate due to a hostile climate.

Timeline for Reform’s Immigration Crackdown

Rapid ECHR Withdrawal: Farage has stated that if Reform UK wins an election, the UK would withdraw from the ECHR as a priority (news.sky.com). Although he hasn’t given an exact timeline publicly, leaving the ECHR is procedurally straightforward – it only requires a 6-month notice under Article 58 of the convention (compas.ox.ac.uk).

In practice, a Reform government would likely issue this notice immediately upon taking office, meaning Britain could be out of the ECHR within the first six months of the term. This aligns with Farage’s aggressive posture (he has indicated he’d act fast, for example by pledging to repeal the Human Rights Act and “disapply” international treaties that hinder deportations (news.sky.com). It’s worth noting that completely effectuating ECHR withdrawal would also require Parliament’s consent and domestic legal changes, such as replacing the Human Rights Act with a new Bill of Rights (compas.ox.ac.uk).

Mass Deportation Legislation: Alongside ECHR withdrawal, Reform UK promises a sweeping “Illegal Migration (Mass Deportation) Bill” to enable fast-track removals (instituteforgovernment.org.uk). Farage’s plan, dubbed Operation Restoring Justice, is to “detain and deport all illegal migrants over one parliament” (compas.ox.ac.uk).

This would entail expanding detention capacity (Reform vows to create 24,000 detention places within 18 months (bylinetimes.com) and running daily deportation flights. Farage has boasted that within 18 months the infrastructure for mass deportations would be in place (bylinetimes.com). However, passing such a radical bill may take time – experts note it could take over a year to get through Parliament, especially given likely resistance in the House of Lords (compas.ox.ac.uk). In summary, the “fast change” promised by Farage would see initial steps (ECHR notice, bill introduction) in months, but full implementation (detention centres, routine flights) unfolding over 1–2 years of a Reform government.

Scale of Migrant Removals and Exits Under Reform

Forced Reapplication for ILR Holders: A cornerstone of Reform UK’s policy is abolishing Indefinite Leave to Remain (ILR) – the status that allows migrants to settle permanently after 5 years in the UK (theguardian.com). Farage has vowed to “entirely abolish ILR”, forcing anyone already on ILR to have it rescinded and reapply for a new visa under much stricter criteria (theguardian.com reuters.com). This puts tens of thousands of legal long-term residents at risk of losing their status and being deported if they don’t meet the new rules (theguardian.com). Under the Reform plan, only those meeting high salary thresholds and English proficiency requirements would qualify to stay, and even then on a renewable work visa with no access to welfare benefits (reuters.com)

• New Migrants in the Pipeline: Farage specifically targeted what he calls the “Boriswave” – an estimated 800,000 people who arrived legally under post-Brexit rules (many from non-EU countries) and would have become eligible for ILR in the next 3–4 years (theguardian.com). Under Reform’s proposal, these 800,000 migrants (2026–2030) would no longer be granted ILR (reuters.com). Instead, they’d face either a tougher 5-year work visa with no benefits or an ultimatum to leave if they don’t qualify.
• Existing ILR Holders: In addition, all migrants currently holding ILR would be impacted. Farage confirmed that those who already have ILR would see it revoked and be forced to reapply under the new system. The exact number of current ILR holders is unclear, but it is likely in the hundreds of thousands (the UK granted ILR to 173,000 people in just the year to March 2025 (reuters.com). Many of these people have lived and worked in the UK for years. If they fail to meet the high income or other requirements, they could face deportation or have to leave voluntarily. In total, between the prospective 800,000 and a substantial share of current ILR residents, the policy could ultimately force on the order of a million migrants out of the UK over a several-year period.

Exemptions and Special Cases: One notable caveat is that Reform UK indicated EU citizens with post-Brexit “settled status” would not automatically lose their rights under this ILR abolition (theguardian.com). A senior Reform figure clarified that the ILR rescinding policy “would not apply to EU citizens granted settled status” – likely to avoid breaching the Brexit Withdrawal Agreement – though Reform hinted at restricting welfare for EU nationals on benefits (theguardian.com). Thus, the focus of ILR removal is on non-EU immigrants who came under work, family, or refugee schemes in recent years (theguardian.com).

Voluntary Exodus Due to Hostile Climate: Beyond those formally targeted by policy, there is a broader concern that many legal migrants (including naturalised British citizens or those on other visas) may choose to leave the UK because of an unwelcoming environment.

The rise of anti-immigrant rhetoric and policies can create a “mood” that drives people away. We have historical precedent: after the 2016 Brexit referendum, when anti-migrant sentiment spiked, tens of thousands of EU citizens decided to leave the UK rather than stay in a country they felt had turned hostile (gov.uk). Indeed, net migration statistics show EU migration flipped negative post-Brexit – in 2022–2023 about 72,000 more EU nationals left the UK than arrived (gov.uk), reflecting EU workers and families departing. We might expect a similar or greater brain drain under a Farage government. Skilled professionals who have the option to work elsewhere could relocate, and even some naturalised Britons of immigrant origin might emigrate if they feel unwelcome or fear for their families’ future. While it’s hard to quantify this effect, it could mean thousands more departures on top of the forced removals. This loss would likely include workers in sectors already struggling to retain talent (for instance, science, tech, healthcare, and academia often rely on international staff).

Economic Consequences of Mass Migrant Removal

Removing such a large number of migrants – many of them working-age, employed, and paying taxes – would have profound negative impacts on the UK economy. Key anticipated effects include:

• Workforce and Skills Shortages: The UK economy is highly dependent on migrant labour across various skill levels. Sectors from hospitality and food processing to construction, agriculture, healthcare and IT rely on foreign-born workers. A sudden mass exodus of up to a million people would create acute labour shortages. For example, even in 2017 after the Brexit vote, industries noted that the surge of EU citizens leaving was “already having a significant impact” on businesses – construction, engineering, and medical fields were highlighted as hardest hit by departing EU workers (theguardian.com). Under a Reform scenario, the effect would be magnified across both high-skill and low-skill jobs. Companies unable to fill vacancies might scale back or relocate, and some essential services could be strained (e.g. fewer healthcare staff just as demand rises). While in theory fewer migrants might tighten the labour market and put upward pressure on wages for some jobs, in practice the disruption and lost productivity would likely drag down growth.
• Reduction in Consumer Demand: Forcibly removing hundreds of thousands of residents means losing that many consumers as well. These migrants contribute to demand in the economy – renting homes, buying goods, using services. Their departure would dampen consumer spending and could hurt sectors like housing (vacancies, rent declines in some areas), retail, and leisure. The overall population shrinkage would likely reduce GDP, since economic output is closely tied to the number of workers and consumers.
• Lower Tax Revenues and Fiscal Costs: Far from saving money, cutting the migrant population would worsen public finances. Migrants, on average, are net contributors to the budget because they tend to be of working age and pay taxes. The UK’s Office for Budget Responsibility (OBR) has explicitly warned that reducing net migration would increase government borrowing and debt (bylinetimes.com). In its March 2024 report, the OBR estimated that a large cut to net migration (on the order of Farage’s proposals) would raise borrowing by £13–£20 billion within five years (bylinetimes.com). Why? Because migrants contribute roughly £19,500 per person per year in taxes on average while also generating additional fee revenues (visa fees, NHS surcharge) (bylinetimes.com). Removing those taxpayers thus blows a hole in the budget. An independent analysis of Reform’s plan found that over five years the UK economy would be about £49 billion smaller due to lost growth, leading to a £17 billion shortfall in tax receipts (plus billions in new costs for enforcement and detention) (bylinetimes.com). In other words, the mass-deportation agenda could create a “trillion-pound black hole” over the long term when you compound lower GDP and higher enforcement spending (bylinetimes.com). The claim by Farage that ending ILR and benefits for migrants would save £200+ billion has been debunked – the think-tank report he cited was withdrawn as “erroneous” (bylinetimes.com). In reality, fewer migrants means fewer taxpayers, a smaller economy, and ultimately less funding for public services, not more.
• Productivity and Innovation Impacts: Many migrants bring skills, entrepreneurship, and innovation to the economy. Highly skilled immigrants (in tech, research, finance, etc.) have been integral to productivity growth. A hostile climate could lead not only to losing existing talent but also deter future skilled workers or international students from coming to the UK. Over time, that brain drain would harm the country’s competitiveness. Sectors like universities and R&D-intensive industries would particularly suffer if international talent pools dry up.
• Sectoral Disruption and Inflation: Some sectors might face sudden imbalances. For instance, agriculture and food processing have long relied on migrant labour for harvests and factory work; deportations could leave crops unpicked or supply chains disrupted, potentially driving up food prices. Care homes and the NHS employ many migrant carers and nurses – staffing shortfalls there could reduce capacity in health and social care, with knock-on economic effects (e.g. more Brits leaving work to care for relatives). Construction and hospitality, already reporting shortages post-Brexit, could see project delays and wage inflation as they compete for a dwindling pool of workers. While higher wages for remaining workers sounds positive, if driven by labour scarcity it can also mean higher costs passed to consumers. In sum, the shock of removing a large chunk of the labour force could contribute to economic stagnation alongside cost-of-living increases in certain areas.

Conclusion

In a “Reform UK comes to power” scenario, the timescales for drastic change would be extremely compressed – Farage’s government would move within months to rewrite laws and withdraw from international obligations, aiming to implement mass deportations within a couple of years. The number of migrants affected would be enormous: roughly 800,000 future ILR candidates denied settlement (reuters.com), plus potentially hundreds of thousands of current ILR holders forced out if they don’t meet new criteria (theguardian.com). Additionally, an atmosphere of heightened xenophobia could prompt many naturalised citizens and long-term residents to emigrate voluntarily, recalling how post-Brexit uncertainty led to tens of thousands of EU nationals leaving the UK (gov.uk).

The economic impact of this mass removal would almost certainly be negative and far-reaching. The UK would lose a substantial part of its workforce and consumer base, leading to lower GDP growth and labour shortages in key industries. The government’s fiscal position would deteriorate as tax revenues fall – lower migration worsens the deficit, rather than improving it (bylinetimes.com). Independent analyses project billions in lost output and higher borrowing as a direct consequence of slashing migrant numbers (bylinetimes.com). In short, following through on these Reform UK policies might satisfy a segment of public opinion hostile to immigration, but it would come at immense economic cost, damaging Britain’s productivity and international standing for years to come.

Sources: Key details have been drawn from recent reporting and analyses. The Guardian, Reuters, and Institute for Government outline Reform UK’s proposals on ILR and deportations (theguardian.com reuters.com / instituteforgovernment.org.uk). The COMPAS Migration Observatory and Sky News discuss the legal mechanics and feasibility of an early ECHR exit. Official data on migration trends (e.g. net EU emigration of ~72,000 in 2022–23) come from the UK Home Office and ONS (gov.uk). Financial impacts are based on OBR figures and a Byline Times economic analysis of Reform’s plan (bylinetimes.com), which challenge Reform’s claims of savings. These sources collectively indicate that a rapid crackdown on migrants with ILR would undermine the UK economy – a case of political promises colliding with economic reality.
