Importing a UK Car to Portugal After Brexit: Why It's More Complicated Than You Think

Before 2021, moving a UK-registered car to Portugal was an EU-to-EU transfer — not simple, but predictable. Post-Brexit, that has changed. The UK is now a third country in EU customs terms. That means customs procedures, potential duty exposure, VAT considerations and homologation requirements that simply did not exist before. This page explains what is actually involved, where the costs come from, and what decisions you need to make before committing.

What Brexit Changed for UK Car Imports

Before 31 December 2020, a UK-registered vehicle moving to Portugal was treated as an intra-EU transfer. The rules were established, the process was relatively predictable, and customs declarations were not required. That framework no longer applies.

The UK's departure from the EU Single Market means UK vehicles entering Portugal are now subject to third-country customs rules. This does not make import impossible — but it does introduce significant additional complexity, cost exposure and documentation requirements compared to importing the same vehicle from Germany or the Netherlands.

Customs Duty: The Rules of Origin Question

This is the most complex part of a UK import — and the one most frequently misunderstood. The answer varies by vehicle and cannot be answered with a simple yes or no.

Under the EU-UK Trade and Cooperation Agreement (TCA), vehicles manufactured in the UK with sufficient UK content may qualify for preferential tariff rates — potentially reducing or eliminating EU customs duty entirely. However, whether your specific vehicle qualifies depends on its Rules of Origin: where it was manufactured and whether its components meet the TCA's origin criteria. This is not a simple determination.

Many vehicles sold in the UK are not manufactured there — they may be German, Japanese, or Korean in origin. For such vehicles, the EU's standard third-country customs duty applies. This is typically cited in the range of 6.5%–10% of the vehicle's CIF value (purchase price plus shipping and insurance), though the exact rate depends on the specific tariff subheading. On a €20,000 vehicle, this represents a meaningful additional cost. Verify your vehicle's applicable rate with a customs agent before committing. For the vehicle's country of origin, check the manufacturer certificate or VIN documentation.

VAT Exposure

Portuguese VAT (IVA at 23%) may apply to vehicle imports from third countries depending on circumstances, including whether the vehicle has been used for at least 6 months and has over 6,000km on the clock (which can affect whether it counts as a "new means of transport" under EU rules). Your residency status and the timing of your move also affect VAT treatment.

Personal effects relief (transferência de residência) — see below — may provide an exemption in specific circumstances. But it is not a guaranteed escape from VAT, and the conditions must be carefully met. For a full breakdown of available exemptions, see the car tax exemptions guide.

ISV Still Applies

ISV (Imposto Sobre Veículos) is Portugal's vehicle registration tax, and it applies to all imported vehicles regardless of origin — including UK imports. The amount depends on the vehicle's CO₂ emissions and engine displacement. Use the ISV calculator above to estimate this for your specific vehicle.

The CO₂ figure used for ISV calculation should come from your vehicle's Certificate of Conformity or V5C. For UK vehicles registered after 2019, this will typically be a WLTP figure. See the WLTP vs NEDC guide to understand which figure to use and why it matters.

Right-Hand Drive: The Practical Reality

RHD is legal in Portugal, but comes with complications

Permanently driving a right-hand drive vehicle in Portugal is permitted, but several mandatory modifications and practical challenges apply. UK headlights dip to the left — for use in Portugal (a right-hand traffic country), they must be adjusted or fitted with beam deflectors. This is a mandatory requirement, not optional.

Homologation and the ITV inspection

RHD vehicles may face additional scrutiny during the Portuguese ITV inspection. Depending on the vehicle's type-approval status and any modifications, the inspector may require evidence of compliance with Portuguese or EU standards. If the vehicle was not EU type-approved (for example, if it was approved under UK-specific rules post-Brexit), the process becomes more complex and potentially requires individual homologation — a time-consuming and expensive procedure.

RHD to LHD conversion

Some importers opt for right-to-left conversion. This is a significant cost (typically several thousand euros for a proper conversion), but may be worthwhile for a high-value vehicle if you plan to remain in Portugal long-term and resell. Conversion quality matters for safety and resale value — use only reputable specialists.

Personal Effects Relief (Transferência de Residência)

Transferência de residência may allow you to import your vehicle free of ISV, VAT and customs duty if you are genuinely relocating to Portugal. The core conditions are: you must have been resident abroad for at least 12 months before the move; the vehicle must have been in your name for at least 6 months prior to your move; the vehicle must be for personal use; and the exemption request must be submitted within 12 months of establishing residence in Portugal.

The conditions are strict and must all be met simultaneously. For UK-origin vehicles post-Brexit, the interaction with customs duty rules adds additional complexity — this is genuinely an area where a Portuguese fiscal representative or specialist customs agent adds real value. See the full exemptions guide for more detail.

Documents Required for a UK Car Import

Important deadline: Once your vehicle enters Portugal, you have 20 working days to submit the Declaração Aduaneira de Veículo (DAV) via the Portal das Finanças and pay any ISV and customs duty due. Missing this deadline results in customs fines and risks vehicle seizure. Start the process as soon as the vehicle arrives — do not wait for paperwork to settle itself.

Import Your UK Car or Sell It? An Honest Comparison

For most UK cars, especially older or right-hand drive vehicles, selling in the UK and purchasing in Portugal is often the more practical choice once customs duty, VAT, RHD complications, and admin costs are factored in.

Importing typically makes sense when: the vehicle is left-hand drive, high-value, or you qualify for transferência de residência and the ISV saving is substantial. It may not make sense when: the vehicle is older with significant customs exposure, RHD complicates homologation, or the total import cost approaches the vehicle's Portuguese market value.

For complex cases — high-value vehicles, RHD, unusual origins, or PHEV/EV — a specialist importer quote is recommended before committing. The main import guide covers the general process for all vehicle origins.

UK imports post-Brexit involve areas of genuine complexity — particularly around customs duty, Rules of Origin and homologation. CarTaxPortugal provides ISV and IUC estimates but is not a substitute for specialist import advice on the customs and VAT dimensions of UK imports. When in doubt, consult a qualified Portuguese customs agent or fiscal representative.

If your UK vehicle is a commercial or N1-classified pickup or van, see the N1 vehicle category guide for additional considerations around ISV classification.

Frequently Asked Questions

Do I pay customs duty when importing a UK car to Portugal after Brexit?
Possibly. The UK is now a third country in EU customs terms. EU customs duty (typically cited in the range of 6.5%–10% of the vehicle's CIF value, depending on the tariff subheading) may apply depending on the vehicle's country of manufacture. If the vehicle was manufactured in the UK with sufficient UK content, it may qualify for preferential tariff rates under the Trade and Cooperation Agreement (TCA). This depends on Rules of Origin — which requires checking your specific vehicle's manufacturing details. This is not a simple question, and the answer varies by vehicle.
Can I permanently drive a right-hand drive (RHD) UK car in Portugal?
Technically yes, but with significant practical complications. Headlight beam adjustment is mandatory (UK headlights dip to the left, Portuguese roads require dipping to the right). Insurance may be more complex for a registered RHD vehicle. Some importers choose to convert to left-hand drive, though this is a significant cost. An RHD import is possible but requires careful planning.
What is 'transferência de residência' and does it apply to UK cars?
Transferência de residência is Portugal's personal effects relief — it may allow you to import your vehicle free of ISV, VAT and customs duty if you are genuinely relocating to Portugal. The core conditions: you must have been resident abroad for at least 12 months; the vehicle must have been in your name for at least 6 months prior to your move; it must be for personal use; and the exemption request must be submitted within 12 months of establishing Portuguese residence. The conditions are strict. For UK-origin vehicles post-Brexit, the customs duty dimension adds additional complexity — always verify with a qualified Portuguese fiscal adviser.
Does ISV apply when importing a UK car to Portugal?
Yes. ISV (the Portuguese vehicle registration tax) applies to all imported vehicles regardless of origin. UK vehicles are not exempt from ISV. The ISV amount depends on the vehicle's CO₂ emissions and engine displacement. Use the ISV calculator to estimate the amount for your specific vehicle.
Do I need a Certificate of Conformity (CoC) for a UK car?
Yes. The CoC is required for Portuguese registration. For UK cars that had EU type-approval before Brexit, the CoC should be available from the manufacturer. For vehicles approved exclusively under UK rules post-Brexit, the situation is more complex and may require individual homologation — which is costly and time-consuming. This is one of the reasons why UK imports require more careful planning than EU imports.
How long can I drive my UK-plated car in Portugal before registering it?
EU rules allow up to 183 days for vehicles brought in by residents of other member states, but the UK is no longer an EU member state. The rules for UK-registered vehicles are different and depend on your residency status. If you are relocating to Portugal, you are generally expected to register the vehicle promptly. Driving on UK plates as a Portuguese resident for extended periods carries legal and insurance risk.
Does my UK MOT certificate count for the Portuguese ITV inspection?
No. A valid MOT does not substitute for the Portuguese ITV (Inspeção Técnica de Veículos). All imported vehicles must pass a separate Portuguese ITV inspection regardless of the origin country's inspection history.
Is it worth importing my UK car to Portugal, or should I sell it?
This depends significantly on the vehicle's value, whether it is right- or left-hand drive, and your eligibility for transferência de residência. For a high-value LHD vehicle where you qualify for the personal effects exemption, importing can make sense. For an older RHD vehicle where customs duty, VAT and homologation all apply, selling in the UK and purchasing locally in Portugal is often more practical and less costly overall.
