Can I use my existing Open category policy to satisfy the PDRA01 insurance requirement?

No. Open category policies are underwritten against a different risk profile and typically exclude Specific category operations by wording. The CAA requires your insurance certificate to explicitly reference Specific category commercial operations. Submit a new application to a specialist coverholder and obtain a policy schedule that names the Specific category before you upload documents to the CAA portal.

Does PDRA01 authorise me to fly over uninvolved people?

PDRA01 permits VLOS operations over controlled ground areas where uninvolved persons are not present or have been excluded by ground control measures. It does not grant blanket permission to overfly uninvolved people. If your mission requires flight over gatherings or public spaces where ground exclusion is not practicable, you will need a bespoke SORA submission or a higher-tier Specific category authorisation, and your insurance programme will need to reflect that elevated exposure.

What happens to my authorisation if I add a new aircraft to my fleet mid-term?

You must notify the CAA of any new aircraft type that is not already covered by your existing authorisation conditions. Simultaneously, notify your insurer so the new aircraft is added to your policy schedule with the correct Specific category classification. Operating a new aircraft under an authorisation that does not list it — even briefly — is a compliance breach that can void both the authorisation and the insurance cover for that aircraft.

How to Apply for a PDRA01 Operational Authorisation

Written by the UK Drone Insurance editorial team · reviewed by Anton Kuznetsov, founder

If you are flying a commercial drone operation that falls outside the Open category — typically because your aircraft exceeds 25 kg, you are operating BVLOS, or your mission profile carries elevated third-party risk — the CAA's Specific category is where your authorisation lives. PDRA01 (Pre-Defined Risk Assessment 01) is the entry-level Specific category route for VLOS operations over controlled ground areas. Before you submit anything to the CAA, your insurance programme must already reflect Specific category exposure. This page walks through the authorisation process and flags the insurance obligations that run alongside it.

What PDRA01 Covers and When You Need It

PDRA01 is a CAA-published pre-defined risk assessment that permits Visual Line of Sight (VLOS) operations in the Specific category without the operator needing to conduct a full bespoke SORA (Specific Operations Risk Assessment). It is designed for operations that are inherently bounded: the aircraft remains within the pilot's unaided sight, the operational volume is controlled, and mitigations are drawn from a fixed menu the CAA has already assessed.

You will need a PDRA01 Operational Authorisation if your operation cannot be conducted lawfully under the Open category — for example, because your drone exceeds the sub-250 g legacy threshold for the relevant Open subcategory, because you are flying over uninvolved people without the specific permissions that Open category rules permit, or because your commercial client contractually requires a Specific category authorisation as evidence of risk management.

PDRA01 does not cover Beyond Visual Line of Sight (BVLOS) flight, operations over crowds, or flights in controlled airspace without a separate Air Traffic Control agreement. If your mission profile includes any of those elements, you will need either a bespoke SORA submission or a higher-tier authorisation such as PDRA02 or a full Specific category approval.

Pre-Application Requirements

The CAA will not process a PDRA01 application from an operator who has not first registered on the CAA's Drone and Model Aircraft Registration Service (DMARES) and obtained a valid Operator ID. If you are the remote pilot as well as the operator, you must also hold a current GVC (General Visual Line of Sight Certificate) or an equivalent legacy qualification recognised under the UK transition framework. Sub-contracted pilots flying under your authorisation must each hold the same minimum qualification.

Before submission, you must have a completed Operations Manual that documents your standard operating procedures, emergency response protocols, maintenance schedule, and crew competency records. The Operations Manual is a live document — the CAA may request amendments at any stage of the review, and your insurer will typically ask to sight it when underwriting your Specific category hull and liability programme.

Insurance is a mandatory pre-condition, not an afterthought. Under UK Air Navigation Order requirements, operators conducting commercial Specific category flights must carry third-party liability cover. The limit required scales with the maximum take-off mass of the aircraft; your broker will confirm the minimum statutory limit in GBP applicable to your fleet. Carry the certificate of insurance with your Operations Manual so both documents are ready for CAA review simultaneously.

The Application Process Step by Step

Applications for a PDRA01 Operational Authorisation are submitted through the CAA's online portal. Log in with your Operator ID credentials, navigate to the Specific category application section, and select PDRA01 as your chosen pre-defined risk assessment. The portal will prompt you to confirm that your intended operations fall within the PDRA01 operational scope — answer each eligibility question accurately, because a mismatch between your declared scope and your actual operations is a compliance breach, not merely an administrative error.

Upload your Operations Manual and insurance certificate as supporting documents. The CAA may request a site-specific risk assessment for your primary operating location, particularly if that location is near an aerodrome, a congested area, or critical national infrastructure. Prepare this document in advance rather than waiting for the CAA to request it; doing so typically shortens the review timeline.

Once submitted, the CAA's UAS team will review your application. Review periods vary depending on application volume and the completeness of your submission. Incomplete applications — most commonly those missing an Operations Manual section or carrying an insurance certificate that does not explicitly reference Specific category operations — are returned for amendment, restarting the clock. Your authorisation, when granted, will specify the operational conditions, the aircraft types covered, and the expiry date. Authorisations are not indefinite; renewal requires a fresh submission and a current insurance certificate.

Insurance Obligations Specific to PDRA01

A standard Open category or hobbyist policy will not satisfy the CAA's Specific category insurance requirement. Your policy wording must explicitly cover commercial Specific category VLOS operations. When you approach a specialist MGA or Lloyd's coverholder, confirm that the policy schedule references the Specific category and that the liability limit meets or exceeds the statutory minimum for your aircraft's maximum take-off mass.

Hull cover is not mandated by regulation but is strongly advisable for commercial operators. Premiums scale with hull value, the complexity of your payload (survey sensors, thermal cameras, and LiDAR units each carry different replacement costs), and the nature of your operating environment. Deductibles on hull claims are typically higher for operations conducted in challenging environments such as offshore, urban canyon, or confined-space inspections.

If you operate a mixed fleet — some aircraft under Open category, others under PDRA01 — your broker must structure the programme so that each aircraft is correctly classified. A single blanket policy that does not distinguish between Open and Specific category aircraft creates a coverage gap: if a Specific category aircraft is involved in a loss and the policy only references Open category operations, the insurer has grounds to decline the claim. Request a schedule that lists each aircraft by registration, category, and authorisation reference.

Maintaining Compliance After Authorisation

A PDRA01 Operational Authorisation is a living permission, not a one-time certificate. The CAA expects operators to notify them of material changes to the operation — new aircraft types, new operating locations that fall outside the original scope, changes to crew, or amendments to the Operations Manual that alter the risk profile. Failure to notify constitutes a breach of the authorisation conditions and may invalidate your insurance, since most Specific category policies contain a condition requiring the operator to maintain regulatory compliance.

Your insurance renewal date and your authorisation expiry date will rarely align perfectly. Build a compliance calendar that tracks both, along with GVC renewal dates for each pilot. A lapsed authorisation means any flight conducted under it is unlawful, regardless of whether your insurance is current. Conversely, a lapsed insurance certificate means your authorisation conditions are breached even if the CAA has not yet been notified.

Incident reporting obligations run in parallel. Under CAA rules, certain occurrences — including airspace infringements, near-misses, and accidents involving injury or significant property damage — must be reported to the CAA's Mandatory Occurrence Reporting system. Your insurer must also be notified promptly; late notification is a common reason for coverage disputes on Specific category claims. Keep both notification procedures in your Operations Manual so that crew can act without delay.
