The Conservative Party’s proposal to implement a legal cap on the number of visas issued each year is set to have far-reaching implications on the UK’s tax revenues and public services.
Net migration, the difference between the number of people entering and leaving the UK, saw a 10% decline in 2023, largely due to fewer arrivals from Hong Kong and Ukraine on humanitarian routes. Home Secretary James Cleverly stated that the Conservative measures, such as limiting visas for dependants of care workers, are already effective. However, these reforms only took effect in 2024, suggesting that the recent drop in net migration is not directly attributable to these changes.
The Tory party claims that their current visa restrictions will result in 300,000 fewer eligible migrants. This figure is derived from Home Office analysis of 2023 migration patterns, indicating who would not have been eligible under the new rules. However, this assumption does not account for migrants possibly finding alternative routes, such as student visas.
The Conservatives propose a new annual visa cap, although the specific number remains undecided. They intend to consult the independent Migration Advisory Committee for a recommendation, which will then be presented to Parliament.
Public sentiment on immigration is mixed, with a significant portion of the population viewing it negatively. A University of Oxford Migration Observatory poll found that a third of people perceive immigration as harmful, while half believe numbers should be reduced. Some evidence suggests that migration pressures public services, such as GP appointments and school places.
Nonetheless, migration also alleviates certain pressures. The NHS relies heavily on migrant doctors and nurses, and reducing migrant inflows could necessitate costly training programs for British workers or higher wages to attract locals to social care roles.
The Office for Budget Responsibility (OBR) highlights that lower migration could increase national debt. In a scenario where net migration drops from an average of 350,000 to 150,000 annually, the OBR predicts that the government’s debt reduction targets would not be met. Migrants, often younger and employed, contribute significantly to tax revenues.
Chancellor Jeremy Hunt’s recent National Insurance cut was based on the assumption of maintaining higher migration levels. Both the Conservative and Labour parties adhere to the same debt rule, suggesting a short-term trade-off between lower migration and potential tax cuts or spending increases.
In the long term, the fiscal impact of migration is considered neutral, as working migrants will eventually retire and draw on state benefits, offsetting their earlier contributions to tax revenues. Ultimately, some may prioritize perceived social cohesion benefits over economic trade-offs, supporting lower net migration despite the short-term financial consequences.
The proposed visa cap by the Conservatives is poised to affect various facets of the UK’s economy and public services. While it aims to reduce net migration, the broader implications on tax revenues, public services, and national debt require careful consideration and balanced policy-making.
