EU vs UK drone compliance: a manufacturer’s guide to dual market access
22 de October de 2026
If you manufacture drones for the European market under EU Regulation 2019/945, you already know how demanding the conformity assessment process can be. If you also want to sell in the United Kingdom, you now need to navigate a parallel regulatory framework that looks familiar but diverges in ways that directly affect your UAS, your marking, and your documentation.
The UK retained the EU drone regulations (Delegated Regulation 2019/945 and Implementing Regulation 2019/947) after Brexit, then amended them through SI 2025/1106 (The Unmanned Aircraft (Amendment) Regulations 2025). The result is not a completely different framework. It is the same structure with targeted changes that create real compliance consequences for manufacturers selling into both markets.
This article covers what has changed, what the key dates are, and how to manage EU and UK drone compliance in parallel without duplicating the effort.

Same structure, different details
The UK drone regulatory framework is built on the same foundation as the EU one. The class structure (seven classes covering the open and specific categories), the weight-based logic, the conformity assessment modules, and the operational categories (open, specific, certified) are all recognisable. A manufacturer who understands EU Regulation 2019/945 will understand the UK version immediately.
The divergences introduced by SI 2025/1106 are specific and targeted. They do not change the overall architecture. They change particular requirements within it, and they introduce a separate marking and certification regime that runs in parallel to the EU system.
Understanding where the requirements are identical and where they diverge is what allows a manufacturer to manage both markets efficiently. The shared territory is large: the EN 4709 test programme, the core product requirements, the conformity assessment methodology. The different territory is narrower: class labels, certain product features, scope boundaries, transition dates, and the certification body structure.
What SI 2025/1106 changes for manufacturers
The amendments introduced by SI 2025/1106 affect four areas immediately and introduce additional requirements from 1 January 2028. The changes that entered into force on 1 January 2026 are already applicable to any UAS placed on the UK market.
Changes in force since 1 January 2026
Class renaming. The EU class designations (C0 through C6) are replaced by UK designations (UK0 through UK6). The numbering, weight bands, and operational logic remain the same, but the labels are different. A C2 label issued under EU Regulation 2019/945 is not a UK2 label under the UK framework. They are separate conformity marks for separate regulatory territories. The class identification label, the declaration of conformity, and the user manual must reflect the UK class when the UAS is placed on the UK market.
Scope exclusion: MTOM below 100g. SI 2025/1106 excludes UAS with a maximum take-off mass below 100g from the product requirements entirely. Under EU Regulation 2019/945, the C0 class covers UAS below 250g and applies product requirements to them. In the UK, a drone under 100g falls outside the product regulation scope regardless of whether it has a camera.
Scope exclusion: enclosed areas. The UK replaces "UAS intended to be exclusively operated indoors" with "UAS designed to be exclusively operated in areas which are wholly or mainly enclosed." The UK formulation is broader, capturing environments such as warehouses, partially covered structures, and other areas that are not strictly "indoors" but are substantially enclosed.
Removal of toy references. SI 2025/1106 removes references to Directive 2009/48/EC (Toy Safety Directive) from the UK version of the regulation. This does not mean connected toy drones are excluded from the regulation, but the specific cross-reference to the EU Toy Safety framework is removed from the UK text.
Additional requirements from 1 January 2028
From 1 January 2028, several new product requirements become mandatory for specific UK classes.
UK0 equipped with a camera will require three new capabilities: a unique serial number compliant with ANSI/CTA-2063-A-2019, a direct remote identification (DRI) system as specified in EN 4709-002, and a geo-awareness function providing alerts about relevant restricted areas. Under the EU framework, C0 drones do not carry these requirements. This is one of the most significant product-level divergences between the two regulatory systems, and it affects any manufacturer producing lightweight camera drones for the UK market.
UK4 will require a unique serial number and a DRI system.
DRI operational requirement for take-off. For all UK classes where DRI is required, the UAS must not be able to take off unless the DRI system is functional and activated. This is a product design requirement: the manufacturer must implement a take-off lock that prevents flight when the DRI function is not operational.
UK1, UK2 and UK3 will require a certificate issued by a UK Conformity Assessment Body. This is a critical change for manufacturers relying on EU Notified Body certificates for the UK market. From 1 January 2028, the EU type examination certificate issued by an EU Notified Body will no longer be valid for placing UK1, UK2, or UK3 drones on the UK market. A separate certificate from a UK-designated conformity assessment body (CAB) will be required.
The timeline that matters
For manufacturers planning their compliance strategy across both markets, the dates that drive decisions are these:
The transition window between 1 January 2026 and 1 January 2028 is the period where manufacturers benefit most from coordinating their EU and UK compliance in parallel. During this window, EU C-class marked drones can still operate in the UK under equivalence. After it closes, each market requires its own marking and, for UK1, UK2, and UK3, its own certification.
One UAS, two markets: the practical approach
The cost of dual EU/UK compliance for a manufacturer already pursuing EU CE marking under Regulation 2019/945 is not double the investment. The technical requirements behind the EU and UK class structures remain aligned at the product design and testing level. What differs is the marking, the documentation, specific feature requirements (UK0 with camera from 2028), and the certification body structure.
A practical approach starts from the design phase:
Define the UAS against both class structures simultaneously. In most cases, the EU class and the corresponding UK class have the same technical requirements at the product level. Identifying any divergences early (particularly UK0 with camera requirements from 2028) prevents redesign later.
Use one EN 4709 test programme for both markets. The EN 4709 standards series covers the product characteristics that both the EU and UK regulations require. A test programme designed to cover the EU requirements will, in most cases, produce evidence sufficient for the UK requirements as well. There is no need to repeat the full test campaign.
Plan for accredited test reports. This is a point that deserves particular attention when the EU Notified Body and the UK Conformity Assessment Body are different organisations. If the test reports supporting the technical file come from an accredited laboratory (ISO 17025), both the EU NB and the UK CAB should accept them without difficulty. If the test reports are not accredited, the second certification body may require significantly more evidence to accept the results, or may require supplementary testing. Coordinating the test strategy to produce accredited reports from the outset avoids this problem. On top of that, special attention shall be paid to the evolution of the UAS configuration (hardware, firmware and software) between the testing stage and the submission for UK certificate, if the tracking a justifications of these evolutions are not well registered the original tests may not be valid.

Manage the marking and documentation as parallel outputs. The class identification label (C vs. UK), the declaration of conformity, the user manual, and any jurisdiction-specific feature configuration (geo-awareness restricted area data, for example) can be managed as parallel document sets produced from the same technical evidence base. This is administrative work, not engineering work.
Address the UK CAB requirement early for UK1, UK2, UK3. From 1 January 2028, these classes require a certificate from a UK-designated CAB. If your EU Notified Body is not also designated as a UK CAB (or vice versa), you will need to engage a separate body for the UK market. Establishing that relationship and understanding the UK CAB's expectations for accepting existing test evidence should be part of the compliance planning, not a last-minute discovery.
A compliance gap assessment identifies what is needed for your specific UAS across both markets.
Frequently Asked Questions
Can I sell my EU C-class marked drone in the UK?
EU C-class marks are recognised as equivalent to the corresponding UK class until 1 January 2028. A C2-marked drone is treated as UK2 for UK operations during this period. From 1 January 2028, EU C-class marks lose their UK equivalence and the drone becomes a "legacy" UAS, subject to weight-based transitional rules that generally offer fewer operational privileges than class-based ones.
Do I need separate conformity assessment for the UK?
The technical evidence (test reports, design documentation) produced for EU compliance is largely reusable. What differs is the marking (UK class label instead of C-class), the declaration documentation, and from 1 January 2028, the certification body. For UK1, UK2, and UK3 from that date, a certificate from a UK CAB is required. If your EU NB is not also designated as a UK CAB, you will need to engage a separate body. When the two certification bodies are different organisations, the validity of the test evidence becomes a practical consideration. Accredited test reports (from an ISO 17025 laboratory) carry their own assurance of validity and should be accepted by the UK CAB without difficulty provided the configuration of the drone (FW, SW, HW) has not substantially changed. Non-accredited test reports present a higher risk: the second certification body has its own obligation to ensure the validity of the results, and without the assurance that accreditation provides, it will likely require additional evidence to accept them. Obtaining that evidence from the first certification body can be difficult, particularly if it involves access to internal assessment records or supplementary testing data.
My drone weighs less than 100g. Does the UK regulation apply?
No. SI 2025/1106 excludes UAS with MTOM less than 100g from the product requirements entirely. This is different from the EU, where C0 covers UAS below 250g and applies product requirements.
Should I pursue EU and UK compliance simultaneously or sequentially?
Simultaneously is more efficient. The technical requirements overlap substantially, and a single EN 4709 test programme can produce evidence for both markets. The 2026-2028 transition window is the period where parallel planning offers the most advantage, because EU C-class marks are still accepted in the UK. Waiting until 2028 to start UK compliance means you lose the equivalence window and may need to engage a UK CAB under time pressure.
What is the most significant product-level difference between EU and UK?
For most UAS classes, the product requirements are aligned. The most significant divergences take effect from 1 January 2028: UK0 with camera will require serial number, DRI, and geo-awareness, while the EU C0 does not carry any of these requirements. UK4 will require serial number and DRI, which also goes beyond the current EU C4 requirements. Additionally, across all UK classes where DRI is required, the UK introduces a take-off lock: the UAS must not be able to take off unless the DRI system is functional and activated.
Can my EU Notified Body issue UK class marking?
Not unless it is also designated as a UK Conformity Assessment Body. EU NB designation and UK CAB designation are separate processes under separate legal frameworks.
