A Guide for UK Pilots: Importing a General Aviation Aircraft from Poland

Overview – Importing a General Aviation Aircraft

The post-Brexit landscape has fundamentally altered the process of acquiring aircraft from the European Union for UK-based pilots. While the European market, particularly a country like Poland with its robust EASA-compliant aviation sector, remains a valuable source of modern and well-maintained general aviation aircraft, the transaction is no longer a simple intra-community transfer. The purchase of a Polish-registered (SP-REG) aircraft by a UK pilot is now a full international import, governed by a complex interplay of Polish export law, UK customs and tax regulations, and stringent UK Civil Aviation Authority (CAA) airworthiness and registration requirements.

This report provides a chronological, phase-by-phase roadmap for navigating this intricate process. It is designed to transform a potentially daunting undertaking into a manageable project by detailing the legal, financial, customs, and airworthiness challenges at each stage. Success hinges on meticulous planning, a clear understanding of the critical path dependencies between each phase, and the engagement of specialist professional support.

Phase 1: Pre-Purchase Due Diligence in Poland

This initial phase involves the vital investigative work required before any financial commitment is made. Thorough due diligence is the primary tool for mitigating the significant transactional risks inherent in an international aircraft purchase.

Legal & Title Verification

The verification process begins with the Polish Civil Aviation Authority (Urząd Lotnictwa Cywilnego – ULC), which maintains the Polish Civil Aircraft Registry. A crucial characteristic of this registry is that it is an “owner registry”. This means the registered owner’s decision and consent are paramount for any changes, including de-registration. The buyer must first verify that the entity named as the seller in the draft purchase agreement is the same entity recorded as the legal owner in the ULC’s registry.   

A significant procedural hurdle is that the ULC’s detailed aircraft registration files are not public. Access is restricted to a limited group of authorized persons, a category to which a prospective foreign buyer does not typically belong. This lack of public access makes it impossible for a buyer to independently verify the aircraft’s full legal history, including its chain of title or any third-party usage rights. Therefore, it is essential for the buyer to insist, as a non-negotiable condition of the sale, that the seller provides a formal power of attorney to a qualified Polish legal representative. This allows the buyer’s representative to access and conduct a thorough analysis of the aircraft’s complete file at the ULC, uncovering its ownership history and any potential legal encumbrances.   

Aircraft Encumbrance Audit

Confirming title is only the first step. The aircraft could be collateral for a loan or subject to other financial claims. A comprehensive encumbrance audit is therefore critical. This involves checking Poland’s national register of pledges (Rejestr Zastawów) for any registered pledges (zastaw rejestrowy) or treasury pledges against the aircraft.   

These encumbrances are not extinguished by the sale of the aircraft. Under Polish law, a creditor holding a registered pledge can exercise their rights and satisfy their claim from the asset, regardless of who the current owner is. A failure to conduct this check could lead to the catastrophic outcome of a buyer purchasing an aircraft that is still legally encumbered by a previous owner’s debt. Furthermore, the ULC file analysis may reveal other rights, such as a lease or a formal right of use held by a third party. These rights also survive the sale, meaning the new owner acquires the seller’s obligations under any existing lease agreement.   

Technical & Airworthiness Records Review

The technical review must be conducted with the end goal in mind: satisfying the stringent requirements of the UK CAA. All aircraft logbooks (airframe, engine(s), propeller(s)), maintenance records, and modification paperwork must be meticulously scrutinized.

Particular attention must be paid to compliance with all applicable Airworthiness Directives (ADs) issued by EASA and the aircraft manufacturer. Any repairs or modifications must be supported by appropriate EASA-approved data, such as a Supplemental Type Certificate (STC) or an EASA Form 1 for installed components. An undocumented modification, even one that was common practice locally, could render the aircraft ineligible for a UK Certificate of Airworthiness (CofA) without expensive and time-consuming rectification or re-certification work.   

Given this complexity, it is highly advisable to engage a UK CAA-approved Continuing Airworthiness Management Organisation (CAMO) to review the technical records at this early stage. A CAMO will assess the records from the perspective of a UK CAA surveyor, identifying potential red flags, paperwork gaps, or non-compliant modifications that could derail the import process later. This early investment can prevent significant future costs and delays.   

The Aircraft Purchase Agreement (APA)

While Polish law does not mandate a specific form for an aircraft sale contract, a comprehensive written agreement is essential for evidentiary purposes and is required to satisfy both the ULC and the UK CAA. For a UK buyer, the APA must include several critical clauses:   

• Conditions Precedent: The buyer’s obligation to complete the purchase should be conditional upon the successful outcome of a pre-purchase inspection, clear title verification, and a clean encumbrance search.
• Delivery State: The agreement must explicitly state that the aircraft will be delivered with a valid Export Certificate of Airworthiness issued by the Polish ULC.
• De-registration Obligation: The seller must be contractually obligated to apply for and secure the de-registration of the aircraft from the Polish register immediately upon the successful transfer of funds.
• Governing Law and Jurisdiction: The contract should clearly specify the governing law and the jurisdiction for resolving any disputes.

Phase 2: The Transaction & Export from Poland

This phase covers the execution of the sale, the legal transfer of ownership, and the formal process of removing the aircraft from the Polish system in preparation for its journey to the UK.

Executing the Sale & Transfer of Title

Once all conditions precedent in the APA have been met, the transaction can be completed. A formal Bill of Sale must be executed; this document is the primary evidence of ownership that will be required by the UK CAA for registration.For high-value assets like aircraft, using a reputable aviation escrow service is strongly recommended. Escrow ensures that the seller’s funds are released simultaneously with the transfer of a clear, unencumbered title to the buyer, protecting both parties.   

The Polish De-registration Process

The process of removing the aircraft from the Polish register is initiated by the owner. As Poland operates an owner registry, the owner has the absolute right to de-register the aircraft, even without the consent of a third-party operator.The application is made to the ULC, and notably, there is no government fee for the de-registration itself. The main practical difficulties are typically logistical, such as physically retrieving the original Certificate of Registration document from the aircraft.   

Upon successful de-registration, the ULC will issue a Certificate of De-registration. This document is a non-negotiable prerequisite for applying to place the aircraft on the UK register.   

Securing the Export Certificate of Airworthiness (CofA)

The single most important airworthiness document in the entire import process is the Export Certificate of Airworthiness, issued by the ULC. It is a formal declaration from the exporting state’s aviation authority that, on a specific date, the aircraft conformed to its approved type design and was in a condition for safe operation.   

This document’s issuance date starts a critical countdown. The Export CofA is valid for only 60 days. The application for a UK Certificate of Airworthiness must be formally submitted to the UK CAA   

before this 60-day period expires. Failure to meet this deadline will result in the UK CAA requiring a full, out-of-sequence Airworthiness Review, adding significant cost and complexity to the project. This 60-day window dictates the timeline for the ferry flight, customs clearance, and all UK-based airworthiness activities.   

A critical sequencing error must be avoided. The Export CofA must be secured before the aircraft is de-registered. Once an aircraft is de-registered, it becomes a “glorified paperweight” with no nationality and cannot be legally flown.Furthermore, the exporting authority (the ULC) loses jurisdiction over a de-registered aircraft and can no longer issue an Export CofA for it. The correct operational sequence is therefore:   

1. Secure the Export CofA from the ULC.
2. Physically fly the aircraft to the United Kingdom.
3. Then, and only then, complete the de-registration from the Polish register.

De-registering the aircraft while it is still in Poland is a critical error that would prevent it from being legally flown to its new home.

Phase 3: UK Importation – Navigating Customs and VAT

Since the UK’s departure from the EU, every aircraft arriving from an EU member state is now subject to full import procedures. This is a significant administrative and financial hurdle that did not exist previously.

Understanding UK Import Obligations

For a UK resident purchasing an aircraft to be based and registered in the UK, a full customs importation is mandatory.The alternative, Temporary Admission (TA), is not a viable option. TA is a customs procedure designed for non-resident users bringing goods into the country for a limited time and for specific purposes; it explicitly prohibits use by local residents or for aircraft based in the territory. Therefore, the buyer must plan for a full import and the associated tax implications.   

The Customs Declaration Process

The import must be formally declared to HM Revenue & Customs (HMRC) using the electronic Customs Declaration Service (CDS). This process is not designed for casual users and presents a steep learning curve. To make a declaration, the importer must first:   

1. Possess a UK Government Gateway user ID.
2. Obtain a GB Economic Operators Registration and Identification (EORI) number.
3. Formally subscribe to the CDS, linking their EORI and Gateway accounts.   

The declaration itself requires specialist knowledge, including the correct customs procedure codes, commodity codes for the specific aircraft type, and other detailed information from the commercial invoice. While it is technically possible for an individual to purchase the necessary software and make the declaration themselves, the complexity is such that the vast majority of importers, and virtually all first-time private importers, use the services of a professional customs agent or freight forwarder. The cost of an agent should be factored into the import budget.   

The final, successfully processed electronic declaration is often referred to by its paper-based predecessor, the Form C88 or Single Administrative Document (SAD). This document is the definitive legal proof that the aircraft has been imported correctly and that VAT has been accounted for.   

Calculating and Paying the 20% Import VAT

While customs duty on civilian aircraft imported into the UK is 0%, import VAT is levied at the standard rate of 20%.This VAT is calculated on the “customs value” of the aircraft, which is defined as the purchase price plus any incidental costs incurred up to the first point of arrival in the UK, such as insurance and ferry flight costs.   

Upon acceptance of the customs declaration via CDS, HMRC will issue a payment demand with a unique 16-character reference number starting with ‘CDSI’. This VAT must be paid promptly before the aircraft is formally released by customs. Payment can be made via several methods, including online banking or bank transfer.   

If the aircraft is purchased by a VAT-registered UK company for genuine business use, it is possible to reclaim the import VAT. This is typically handled using Postponed VAT Accounting (PVA), which allows the business to declare and reclaim the import VAT on the same VAT return, providing a significant cash-flow benefit. It is crucial to note that only the legal owner or lessor of the aircraft can reclaim the VAT, so the purchasing structure must be correctly established from the outset. Professional tax advice is essential if pursuing this route.   

The following table summarises the key HMRC services and documents involved in the import process.

Phase 4: Achieving UK Airworthiness

With the aircraft legally imported, the next major phase is achieving UK airworthiness certification. Post-Brexit, an EASA CofA from Poland is not automatically recognised for placing an aircraft on the UK register. The aircraft is treated with the same procedural rigour as an import from any other non-UK, ICAO state, and it must be issued with a new UK Certificate of Airworthiness by the CAA.

The Critical Distinction: Part 21 vs. Non-Part 21 Aircraft

Aircraft type design requirements fall into two main categories: Part 21 and non-Part 21.   

• Part 21 aircraft are those that fall under the scope of the UK Basic Regulation (UK (EU) 2018/1139). This includes the vast majority of modern, series-produced general aviation aircraft that one would typically find for sale in Poland. This report focuses on this pathway.   
• Non-Part 21 aircraft are those excluded from the Basic Regulation, such as certain vintage, ex-military, or amateur-built types listed in Annex I. These aircraft follow a different process to obtain a National CofA.   

The Path to a UK Certificate of Airworthiness (CofA)

The owner, or more typically their appointed CAMO, must apply to the UK CAA for a new CofA using the dedicated online application form. The cornerstone of this application is the Export CofA obtained from Poland, which must have been issued no more than 60 days before the CAA receives the application.   

The UK CAA issues a non-expiring CofA, which must be validated by a valid Airworthiness Review Certificate (ARC) to be operational.   

The Airworthiness Review Certificate (ARC) and Import Survey

Before the CAA will issue the initial UK CofA for an imported aircraft, it must undergo a full airworthiness review conducted by a UK CAA-approved CAMO. This is a comprehensive process that involves:   

• A detailed physical survey of the aircraft to assess its condition and conformity to the approved type design.
• A meticulous review of all technical records, including logbooks, AD compliance status, and modification history.
• A mandatory check flight for any used aircraft being imported into the UK.   

Upon successful completion of this review, the CAMO will make a formal recommendation to the CAA for the issuance of the initial UK ARC (typically on a CAA Form 15b for privately operated aircraft). The CofA and the initial ARC are then usually issued together by the CAA.   

The Central Role of the CAMO

For any Part 21 aircraft import, a UK CAA-approved Part-CAMO is an indispensable partner. The CAMO effectively acts as the technical project manager for the entire airworthiness phase. Their role includes conducting the pre-purchase records review, liaising with the seller on documentation, managing the CofA application with the CAA, performing the mandatory import survey and review, and developing the UK-compliant Approved Maintenance Programme (AMP) that will govern the aircraft’s future maintenance. The selection of a competent and experienced CAMO is one of the most critical decisions the buyer will make.   

The table below provides a checklist of the key airworthiness documents required.

Phase 5: UK Registration and Preparation for Flight

This phase covers the final administrative and physical steps to officially place the aircraft on the UK Civil Aircraft Register (known as G-INFO) and prepare it for flight.

The G-Registration Process: A Step-by-Step Guide

The process of registering the aircraft in the UK is a relatively straightforward administrative task, provided all the necessary prerequisite documents have been secured from the preceding phases.

• Eligibility: The buyer must meet the CAA’s ownership eligibility criteria. These are quite broad, including British citizens, nationals of any EEA state, and companies formed within the EEA, among others.   
• Application: The application is made online using CAA Form CA1.   
• Documentation: The completed CA1 form must be submitted with:
  1. Proof of Ownership: The Bill of Sale from the transaction.   
  2. Proof of De-registration: The Certificate of De-registration from the Polish ULC.   
  3. Proof of Insurance: Evidence of a valid UK insurance policy, or a formal declaration that insurance will be in place before the aircraft’s first flight.   
  4. Proof of Identity: A copy of the applicant’s photo page from their passport or driving license.   
• Fees: A registration fee is payable, which is based on the aircraft’s Maximum Take-Off Mass (MTOM). For a light aircraft under 15,000 kg, the standard fee is modest (currently £94). Additional fees apply for reserving an out-of-sequence registration mark or for requesting an expedited same-day service.   

Physical Requirements

Once the CAA assigns a UK registration mark (e.g., G-XXXX), several physical changes must be made to the aircraft:

• Registration Marks: The previous Polish “SP-” registration marks must be removed. The new G-marks must be applied to the aircraft fuselage and/or wings in accordance with UK regulations concerning size, location, font, and legibility.   
• Identification Plate: A fireproof ID plate displaying the new UK registration must be securely affixed to the aircraft structure in a prominent position near the main entrance.   
• Radio Station Licence: The aircraft’s radio transmission equipment requires a separate licence. This is not issued by the CAA but by the UK’s communications regulator, Ofcom, and must be applied for separately.   

Securing Mandatory UK Aircraft Insurance

It is a legal requirement to have insurance in place before any flight is undertaken in a UK-registered aircraft. Securing this insurance is not a final step but a critical enabler of the registration process itself, as evidence of cover is required with the application.   

• Minimum Liability Cover: UK law mandates a minimum level of third-party liability insurance. The required amount is determined by the aircraft’s MTOM and is specified in Special Drawing Rights (SDRs), an international currency unit. Owners must ensure their policy meets or exceeds this statutory minimum.   
• Hull Insurance: While not legally mandatory, hull insurance is almost universally purchased. It covers physical loss or damage to the aircraft itself. Policies are typically arranged on an “agreed value” basis, where the payout in the event of a total loss is a pre-agreed sum, rather than the market value at the time of the loss.   
• Cost Factors: Insurance premiums vary widely based on the aircraft’s agreed value, its type, and crucially, the experience and qualifications of the named pilots (total hours, hours on type, ratings held). Annual premiums for a typical four-seat light aircraft can range from £1,500 to over £3,000, with costs having risen in recent years.   

Phase 6: Pilot Licensing and Operational Considerations

The final piece of the puzzle is ensuring the pilot is legally qualified to fly the aircraft at each stage of its journey from a Polish-registered asset to a UK-registered one. The pilot’s licence is a distinct but parallel workstream to the aircraft’s importation.

The Ferry Flight: Poland to the UK

The aircraft must be flown from Poland to the UK while it is still on the Polish (SP-) register, before de-registration is completed. The pilot conducting this flight must hold a licence with privileges valid for an SP-registered (i.e., EASA) aircraft. This will typically be an EASA Part-FCL licence with the appropriate class or type rating. A UK-based pilot who holds only a UK Part-FCL licence may not be legally qualified to act as pilot-in-command for this flight. The most straightforward solution is often to hire a professional ferry pilot with the required EASA credentials.   

Flying a Foreign-Registered Aircraft in the UK

The regulations are designed to prevent UK residents from basing and operating foreign-registered aircraft in the UK long-term as a way to circumvent UK rules. While a genuine “visiting pilot” can fly a foreign-registered aircraft in the UK under certain conditions, the rules for a UK resident are much stricter. If the aircraft’s operator is a UK resident or has their principal place of business in the UK, the pilot must hold a UK-issued licence or a specific validation from the CAA. The “28-day declaration” system is for visitors and is not a viable long-term solution for a UK-based owner. This regulatory framework effectively closes any potential loophole and reinforces the necessity of the full import and re-registration process.   

Validating Your Pilot Licence for Your New G-Reg Aircraft

Once the aircraft is successfully placed on the G-register, the rules change again. To act as pilot-in-command of a G-registered aircraft, a pilot must hold a licence issued or validated by the UK CAA.   

Post-Brexit, an EASA licence issued by another member state (such as Poland) is no longer automatically sufficient for flying a G-registered aircraft. A pilot holding an EASA licence must undergo a conversion process to obtain a UK Part-FCL licence. This process typically involves passing UK-specific theoretical knowledge examinations in Air Law and Human Performance, and may also require a skill test with a UK examiner. A buyer holding an EASA licence should initiate this conversion process with the CAA well in advance to ensure their UK licence is in hand when the aircraft is ready to fly on its new G-registration.   

Conclusion and Expert Recommendations

The importation of a general aviation aircraft from Poland to the UK is a multi-faceted project that demands careful, sequential execution. It is no longer a simple administrative task but a full customs and regulatory import that is fraught with potential pitfalls for the unprepared. However, with a clear understanding of the process and professional support, it is an entirely achievable goal.

Critical Path Summary

The following checklist summarises the major sequential milestones of the import project:

1. Engage Professional Team: Secure the services of a Polish lawyer, a UK CAMO, and a UK customs agent.
2. Conduct Full Due Diligence in Poland: Verify title, check for encumbrances, and have the technical records reviewed by the UK CAMO.
3. Execute APA and Secure Funding: Finalise the purchase agreement and use an escrow service for payment.
4. Obtain Polish Export CofA: This action starts the critical 60-day clock for the UK CofA application.
5. Ferry Aircraft to UK: Fly the aircraft to its new UK base while it is still on the SP-register, using an EASA-licensed pilot.
6. Complete Polish De-registration: Secure the de-registration certificate from the ULC.
7. Submit UK Customs Declaration and Pay VAT: The customs agent submits the CDS declaration and the buyer pays the 20% import VAT.
8. Submit UK Registration (CA1) Application: Apply to the CAA with the Bill of Sale, de-registration certificate, and proof of insurance.
9. UK Airworthiness Review: The UK CAMO conducts the physical survey, records review, and check flight.
10. UK CAA Issues Airworthiness Certificates: The CAA issues the non-expiring CofA and the initial ARC.
11. Final Preparations: Apply G-marks, install the ID plate, and obtain the Ofcom radio licence.
12. Fly: Operate the aircraft on its new G-registration with a UK-licensed pilot.

The Importance of Professional Support

Attempting this process without a team of specialists is a false economy. The potential for costly errors far outweighs the fees for professional services. A Polish lawyer is essential for navigating the local registry and legal system. A customs agent is a practical necessity for dealing with HMRC’s complex CDS system. Most importantly, an experienced UK CAMO is the central technical partner required to manage the entire airworthiness transition and liaise with the CAA.   

Final Pre-Purchase Checklist

Before committing any funds, a buyer should be able to answer “yes” to the following questions:

• Has a Polish legal representative confirmed clear title and no encumbrances after reviewing the ULC files and pledge register?
• Has a UK CAMO reviewed the aircraft’s technical records and confirmed there are no major airworthiness issues that would prevent a UK CofA from being issued?
• Is there a comprehensive Aircraft Purchase Agreement in place that obligates the seller to provide an Export CofA and cooperate with de-registration?
• Has a plan and budget been established for the ferry flight, the 20% UK import VAT, and the fees for the CAMO and customs agent?
• Has the pilot confirmed their licensing status for both the ferry flight (EASA) and future UK operations (UK Part-FCL) and started any necessary conversion process?
