Sub-250g Drone Commercial Use in the UK

No Separate Commercial Licence Required

One of the most common misconceptions about UK drone law is that you need a special commercial permit to earn money with your drone. That has not been the case since the CAA adopted the Open Category framework in 2020. Whether you fly for fun or for profit, the same set of rules applies to sub-250g drones operating in the Open Category.

This means a real estate photographer, a wedding videographer, and a hobbyist flying in the park all follow identical airspace and operational rules, provided they stay within the Open Category limits.

What You Still Need for Commercial Flights

Although no commercial licence exists, flying for business purposes comes with responsibilities that go beyond recreational use:

• Operator ID: Every commercial operator must register with the CAA and obtain an Operator ID. This is displayed on the drone itself. The cost is minimal and registration is completed online through the CAA portal.
• Flyer ID: You need a Flyer ID, obtained by passing the CAA online theory test. This confirms you understand basic airspace rules and safety obligations.
• Insurance: While not strictly mandated by law for recreational sub-250g flights, commercial operators should carry third-party liability insurance. Clients and contracts frequently require proof of coverage before work begins.
• Risk assessment: Good professional practice demands a documented risk assessment before each commercial flight, covering hazards such as nearby people, structures, and weather conditions.

Open Category Subcategories Explained

The Open Category is divided into three subcategories, each with different proximity and altitude rules. Sub-250g drones benefit from the most relaxed requirements:

A1 — Over Uninvolved People

Class C0 drones (under 250g) may fly over uninvolved people in subcategory A1. You do not need to maintain a fixed horizontal distance from bystanders, though you must never fly over assemblies of people. This makes sub-250g drones particularly attractive for commercial operators working in populated areas such as town centres or residential streets.

A2 — Close to People

Subcategory A2 applies to heavier drones (C1 and C2 class) and requires additional competency. Sub-250g operators generally operate under A1 and do not need A2 certification.

A3 — Far from People

Subcategory A3 covers flights in areas where uninvolved people are unlikely to be present. Any drone, including sub-250g models, may operate here with minimal requirements.

Industries Using Sub-250g Drones Commercially

The lightweight, accessible nature of sub-250g drones has opened commercial opportunities across many sectors:

• Real estate: Aerial photographs and video tours of properties for estate agents and developers.
• Events: Wedding and corporate event coverage from elevated perspectives.
• Agriculture: Crop inspection and field mapping on smaller holdings.
• Construction: Progress monitoring and site surveys where heavier platforms are unnecessary.
• Content creation: Social media, YouTube, and marketing material production for brands and businesses.

When You Might Need an Operational Authorisation

If your commercial work requires flying outside the Open Category limits — for example, beyond visual line of sight (BVLOS), above 120 metres, or in restricted airspace — you will need an Operational Authorisation from the CAA under the Specific Category. This involves submitting a detailed risk assessment (often using the SORA methodology) and demonstrating appropriate competency.

For the vast majority of sub-250g commercial operations, however, the Open Category provides sufficient scope to complete work legally and safely.

Tax and Business Obligations

Earning income from drone flights triggers standard business obligations. You must register as self-employed with HMRC or operate through a limited company. Keep records of income and expenses, and file tax returns accordingly. The drone regulations themselves do not distinguish between business structures, but your financial and contractual obligations exist regardless of aircraft weight.

Practical Tips for Commercial Sub-250g Operators

• Always carry proof of your Operator ID and Flyer ID on site.
• Secure written permission from landowners before take-off on private property.
• Brief your client on what is and is not permitted under current airspace rules.
• Check NOTAM (Notice to Airmen) information before every flight using the NATS Drone Assist app or similar tools.
• Consider joining a professional body for access to group insurance rates and industry updates.
