Chapter 1. Regulatory Framework Overview
1-1. Governing Body
The Civil Aviation Authority (CAA) is the sole statutory regulator for drone operations in the United Kingdom. It derives authority from the Civil Aviation Act 1982 and the Air Navigation Order 2016 (as amended). Post-Brexit, the UK has retained the substance of EU drone regulations as domestic law — but divergences are emerging and operators must follow UK-specific rules, not EASA guidance.

1-2. Core Regulatory Framework
| Regulation | Full Title | Status | Scope |

| Air Navigation Order 2016 | Air Navigation Order 2016 (SI 2016/765) as amended | In force | Overarching UK aviation law; UAS provisions in Part 5 and Schedule 8 |
| UK Reg (EU) 2019/947 | Regulation on rules and procedures for the operation of unmanned aircraft (retained EU law) | In force (UK version) | Open and Specific Category operations framework |
| UK Reg (EU) 2019/945 | Regulation on unmanned aircraft systems and third-country operators (retained EU law) | In force (UK version) | UK class mark requirements (UK0–UK6) |
| UK Reg (EU) 785/2004 | Insurance requirements for air carriers and aircraft operators (retained EU law) | In force (UK version) | Third-party liability insurance for commercial operations |

1-3. Three-Category Structure
| Category | Risk Level | Authorisation Required | MmowW Target |
|---|---|---|---|
| Open | Low | No (self-declaration, rules-based) | ❌ Out of scope |
| Specific | Medium | Yes — Operational Authorisation (OA) from CAA | ✅ Core target |
| Certified | High | Yes — equivalent to manned aviation certification | ❌ Out of scope |
MmowW UK targets Specific Category operators. Estimated 2,900 active OA holders in the UK (approximately 2,800 PDRA01 holders + approximately 100 SORA/LUC holders). These operators have a legal obligation under UK Reg (EU) 2019/947 Article 11 to maintain operations manuals, flight logs, technical logbooks, and insurance records available for CAA inspection at any time.
1-4. Post-Brexit UK vs. EASA Divergences
This is a critical distinction for UK operators. The UK left the EU Single Aviation Market on 31 December 2020. Operators and equipment certified under EASA rules are not automatically valid in the UK unless specifically recognised.
| Topic | EU (EASA) | UK (CAA) | Practical Impact |
|---|---|---|---|
| Drone class marks | C0–C4 (EU CE marking) | UK0–UK6 (UK CA marking) | EU C-class marks are accepted in UK until 31 Dec 2027 only |
| Pilot qualification | EASA A2 CofC / STS-01 / GVC | UK A2 CofC / RPC-L1 / GVC (transitional) | EU-issued qualifications not automatically valid in UK |
| Operational authorisation | EASA-issued STS/PDRA | CAA-issued OA (PDRA01 / UK SORA) | No mutual recognition — UK operators need UK OA |
| Remote ID | EU broadcast requirement | UK broadcast requirement (phased 2026–2028) | Timetable broadly similar but UK-specific classes |
| Insurance | EU Reg 785/2004 | UK Reg (EU) 785/2004 (retained) | Substantively identical — UK-authorised insurer required |
| Accident reporting | EASA/national AIB | UK AAIB | All accidents reported to AAIB, not EASA |
| Airspace tools | National ATM systems | NATS SkyWise / CAA-approved tools | Dronecode and NATS Drone Assist are UK-specific |
Key principle for UK operators: If you hold an EASA qualification or fly an EU-marked drone, verify UK-specific validity before each operation. "EASA approved" does not mean "CAA approved" post-Brexit.
1-5. Regulatory Change Monitoring
CAA publishes regulatory updates at: https://www.caa.co.uk/drones/rules-and-regulations/
Operators should subscribe to CAA email alerts and monitor CAP revisions. MmowW's law patrol monitors this page daily.

| Your Situation | What You Need | Go To |
|---|---|---|
| Hobby pilot, small drone (<250g) | Registration only | Chapter 2 |
| Commercial operator, standard drone | Full pilot certification + registration | Chapter 2–3 |
| Flying near airports or restricted zones | Airspace authorisation required | Chapter 3 |
| Night flights or beyond visual line of sight | Special operational approval | Chapter 3 |
| Incident or accident occurred | Mandatory reporting obligations | Chapter 4 |
| Insurance and maintenance questions | Third-party liability + maintenance log | Chapter 5 |
5-second answer: If your drone weighs more than 250g, you need pilot certification AND aircraft registration before your first flight.
