International contract assignments are a significant and growing feature of technical aviation recruitment across Europe. With demand for licensed engineers running well ahead of supply in many markets, and with many experienced professionals valuing the financial and lifestyle benefits of contract working, cross-border placements have become a substantial part of how the European aviation talent market functions. However, international contracting involves genuine regulatory, tax and employment law complexity that both contractors and the organisations engaging them need to manage properly.
The Posted Workers Directive
The EU Posted Workers Directive applies to temporary assignments where an employee based in one EU member state is sent to work in another. The core practical obligation is that minimum employment conditions — relating to pay, working hours, holidays and health and safety — must meet the standards of the host country rather than the home country where the host country standards are higher. In practice, most aviation contractor placements through reputable staffing companies are structured in a way that satisfies the Directive’s requirements. However, the administrative obligations — including notifications to host country labour authorities in several EU member states — must be properly managed. Contractors working through staffing companies should satisfy themselves that their agency has the relevant country-specific compliance infrastructure in place.
Tax Residency and Social Security
The tax treatment of international contractors is highly dependent on individual circumstances: the contractor’s country of tax residence, the countries in which work is performed, the duration of the assignment, and the structure of the engagement. In broad terms, contractors on short-term assignments of under 183 days in a tax year in a foreign country may be able to maintain sole tax residency in their home country under double taxation treaty provisions — but this is not automatic and requires careful management and proper professional advice.
Protec Technical works with specialist international payroll and tax advisers who can support contractors on European assignments with appropriate structuring and compliance. We raise this with candidates at the start of any cross-border placement discussion and ensure the compliance position is properly understood before any assignment begins.
EASA Licences and UK CAA Post-Brexit
For UK-licensed engineers, the post-Brexit position requires attention. UK CAA Part-66 licences are not automatically recognised in EASA member states. UK engineers working within EASA-regulated Part-145 approved organisations on the continent will generally need to hold or convert to an EASA Part-66 licence. The conversion process is well-established and manageable — particularly for engineers with long UK CAA licence histories — but it takes time and requires advance planning. Protec Technical works with a specialist aviation licensing adviser who can guide candidates through the conversion process, and we flag the licensing position clearly at the outset of any placement discussion that involves a UK-licensed engineer working in an EASA environment.
