After Brexit, UK Part 1 registration remains open to boat owners, but the route to it has changed. Non-UK nationals can no longer register a vessel in their own name; they must use a UK Limited company. This guide explains who qualifies, what documents are needed, how long it takes, and what to do next.
What Is UK Part 1 Registration?
Part 1 is the full UK register of ships, held by the Maritime and Coastguard Agency (MCA). It records the vessel and its ownership in one official document: the Certificate of Registry. That certificate is recognised internationally and is often the document foreign authorities ask to see.
Part 1 is different from the Small Ships Register (Part 3), which is a simpler, cheaper option for pleasure craft used mainly in UK waters. Part 1 involves a more detailed application, including evidence of ownership and, in many cases, tonnage measurement.
For owners who cruise abroad, finance a purchase, or want clear proof of title, Part 1 is usually the more practical choice. It also allows a vessel to be registered in the name of a company, which matters for many owners after Brexit.
Why Brexit Changed the Rules for Many Owners
Before Brexit, an EU resident could often register a yacht on the UK Part 1 register in their own name. That route is now closed for non-UK nationals. If you are not a UK national, you generally cannot register a Part 1 vessel personally.
The workable alternative is a UK Limited company. The company becomes the registered owner, and the vessel is registered in the company’s name. This is a well-established structure, but it must be set up correctly before the registration application is submitted.
One important limitation: BlueWater does not accept a client’s existing UK Limited company for this purpose. If you already own a UK company, it cannot simply be slotted into the application. A new company is created and managed as part of the service.
If you are a UK national, personal registration may still be possible, depending on the vessel and the eligibility criteria. The right route depends on your nationality, residence and how the boat will be used.
Who Qualifies for UK Part 1 Registration?
Eligibility is assessed by the MCA, not by BlueWater. The key points to understand are:
- UK nationals may be able to register in their own name, subject to the MCA’s eligibility criteria.
- Non-UK nationals can generally only register through a UK Limited company structure.
- Corporate owners must use a UK Limited company. BlueWater creates and manages this company as part of the process.
- Existing companies owned by the client are not accepted for this route.
- Previously UK-registered vessels that were deleted from the register need a deletion certificate before they can be re-registered.
If your vessel was registered in the UK before and later removed, do not skip this step. Without the deletion certificate, the new application cannot proceed.
What Documents Are Needed?
A Part 1 application is a dossier, not a single form. Missing or unclear documents are the most common reason applications stall. The core items are:
- Full vessel details, including dimensions and identification.
- Evidence of ownership, such as a builder’s certificate or a bill of sale.
- Tonnage measurement documentation, where required.
- Proof of eligibility for the owner or owning company.
- A deletion certificate, if the vessel was previously on the UK register and has been removed.
Two problems come up again and again. The first is an unclear ownership chain, where the paperwork does not show a clean transfer from one owner to the next. The second is a missing builder’s certificate, which is difficult to replace after the fact. Checking these early saves weeks later.
Tonnage Measurement: Who Needs a Full Survey?
Tonnage is where many owners expect the worst and are pleasantly surprised. For pleasure vessels under 24 metres, a full tonnage survey is typically not required if basic dimensions are sufficient. That covers a large share of private yachts.
The picture changes for commercial vessels, passenger ships and certain high-speed craft. These face stricter certification requirements, and a full measurement process is more likely. If your vessel falls into one of these categories, plan for more documentation and more time.
Historic vessels may qualify for simplified procedures if they are properly documented. This is assessed case by case, so the quality of your historical paperwork matters.
How Long Does Registration Take?
From receipt of a complete and eligible application, standard processing is around three to four weeks. An ultra-fast option is available as an add-on and can bring this down to roughly three to four working days.
The word «complete» carries real weight here. The clock starts when the dossier is in order, not when you first make contact. An unclear ownership chain or a missing certificate will pause progress regardless of which speed you choose.
If you have a fixed departure date or a completion deadline on a sale, work backwards from that date and allow time for document gaps to be resolved.
What Does BlueWater’s UK Part 1 Service Include?
BlueWater Registration Services coordinates the full dossier submission to the UK MCA. For owners who need the company structure, the service also handles incorporation and the registered office.
For boats from 1 m in private use, the service starts from €1,350 excl. VAT. This includes UK Limited Company Incorporation, the Official UK Part 1 Certificate of Registry, the Official Certificate of Incorporation, and registered office service for the first year.
For boats from 1 m in commercial use, the service starts from €1,950 excl. VAT. This includes UK Limited Company Incorporation, the Official UK Part 1 Certificate of Registry, the Official Certificate of Incorporation, registered office service for the first year, and a Safe Manning Certificate.
These are starting prices, not fixed totals. The final figure depends on your vessel and circumstances, and a formal written quotation is provided after assessment.
One scope point to be clear about: these two options are the complete list of what BlueWater arranges for UK Part 1. If your boat length or use does not fall within one of them, this option does not apply, and BlueWater cannot quote one of these prices for it.

What About Cruising and VAT After Brexit?
This is the area where owners most often want a simple answer and there isn’t one. Post-Brexit cruising access and VAT treatment vary by destination. They can also depend on the vessel’s prior VAT status and its cruising history.
There is also uncertainty about whether EU-flagged vessels transferring to UK registration after Brexit need additional customs clearance documentation, again depending on prior VAT status and history. These are customs questions, not registration questions, and they are decided by the relevant customs authorities rather than by the MCA or by BlueWater.
The practical approach is to treat registration and customs as two separate workstreams. Get the registration dossier right, and separately confirm the VAT and cruising position for the specific countries you plan to visit with the customs authority concerned.
A Practical Example
Consider a hypothetical owner: a Dutch resident who buys a 15-metre sailing yacht and plans to cruise the Mediterranean and later cross to the Caribbean. Because he is not a UK national, he cannot register Part 1 in his own name. The route is a UK Limited company, created as part of the service, with the yacht registered in the company’s name.
At 15 metres and in private use, a full tonnage survey is typically not required if basic dimensions are sufficient, which simplifies his dossier. His real risks are an incomplete ownership chain from the previous owner and a missing builder’s certificate. Sorting those out first keeps him inside the standard three-to-four-week window. Separately, he confirms VAT and cruising requirements for each destination with the relevant customs authorities.
What Should You Do Next?
Work through these steps in order:
- Confirm your nationality and whether you need a UK Limited company structure.
- Gather ownership evidence, the builder’s certificate or bill of sale, and any deletion certificate.
- Check whether your vessel needs full tonnage measurement or qualifies for the simpler route.
- Decide whether standard or ultra-fast processing suits your timeline.
- Separately confirm VAT and cruising requirements with the relevant customs authorities.
The most useful first move is a personalised assessment. Complete the contact form with your vessel details and ownership situation, and you will receive a formal written quotation based on your actual circumstances rather than a general estimate.
Conclusion
UK Part 1 registration after Brexit is still a practical route for yacht and boat owners, but non-UK nationals now need a UK Limited company to do it. The application itself is a document exercise: ownership evidence, tonnage where required, and eligibility proof. Get those right and processing from a complete, eligible application runs around three to four weeks, or roughly three to four working days with the ultra-fast add-on.
Keep registration and customs separate in your planning. Registration is handled through the MCA; VAT and cruising access depend on your destinations and history and must be confirmed with the relevant customs authorities. For private use, BlueWater’s service starts from €1,350 excl. VAT; for commercial use, from €1,950 excl. VAT, each including company incorporation, the Official UK Part 1 Certificate of Registry, the Official Certificate of Incorporation and first-year registered office service, with a Safe Manning Certificate added for commercial vessels. These are starting prices, and a formal quotation follows assessment.
BlueWater Registration Services can assist with further guidance, from eligibility checks through to full dossier submission to the UK MCA. If you are unsure which route applies to your vessel, start with an assessment before you commit to a timeline.
