CAA OA Paragraph 6 Drone Underwriting | UK

What Paragraph 6 of a CAA Operational Authorisation Actually Requires

Under the UK's three-tier regulatory framework — Open, Specific, and Certified — any operation that cannot be conducted under a standard scenario (STS) or a pre-defined risk assessment (PDRA) requires a bespoke Operational Authorisation from the CAA. Paragraph 6 of that OA is the insurance clause. It mandates that the operator maintains in-force third-party liability insurance that is appropriate to the nature and scale of the operation described in the authorisation.

The CAA does not prescribe a single minimum limit in the OA text itself; instead, it cross-references EU Regulation 785/2004 as retained in UK law, which sets liability minima by maximum take-off mass (MTOM) expressed in Special Drawing Rights. The practical consequence is that your insurer must be able to confirm, in writing, that the policy responds to the specific operation, aircraft class, and geographic scope stated in your OA — not just to drone operations generically.

Paragraph 6 also creates a continuing obligation. If your insurer cancels, voids, or materially restricts the policy mid-term, your OA is simultaneously at risk. Underwriters who are unfamiliar with this linkage may issue policies with endorsements — autonomous operations exclusions, payload exclusions, or BVLOS sub-limits — that inadvertently breach Paragraph 6 without either party realising it until a claim or a CAA audit.

How Underwriters Assess Paragraph 6 Risk

Specialist drone underwriters approach Paragraph 6 submissions through the lens of the operator's SORA-derived risk assessment, which the CAA uses to determine the OA's operational conditions. The SAIL (Specific Assurance and Integrity Level) outcome, the adjacent area classification, and the robustness of the operator's ConOps all feed directly into how an underwriter prices and structures the liability layer.

Hull underwriting for Specific-category aircraft is driven by a different set of variables than Open-category hobbyist cover. Agreed value versus market value elections, the presence of payload sensors or specialist equipment, and whether the aircraft operates under a manufacturer's approved maintenance programme all affect hull terms. For bespoke or prototype platforms — common in survey, inspection, and emergency-services contracts — underwriters will typically require a technical specification sheet and evidence of airworthiness management.

BVLOS operations attract the most scrutiny. Premiums scale with hull value and BVLOS exposure, and deductibles typically rise on autonomous operations where the pilot-in-command's ability to intervene is reduced. Underwriters will want to see the detect-and-avoid solution, the communications architecture, and any CAA-imposed operational limitations before quoting. A submission that arrives without these documents will either be declined or quoted on restrictive terms that may not satisfy Paragraph 6.

• SORA SAIL level and adjacent area classification
• Aircraft MTOM and payload configuration
• BVLOS vs VLOS operational profile
• Detect-and-avoid and C2 link redundancy evidence
• Maintenance and airworthiness management records
• Geographic scope and any overwater or congested-area exposure
• Operator's claims history across all aviation lines

Structuring the Policy to Satisfy Paragraph 6

A Paragraph 6-compliant policy must name the correct insured entity — the legal person or organisation that holds the OA — and must not contain exclusions that carve out the operations described in the authorisation. This sounds straightforward, but standard aviation liability wordings frequently contain exclusions for unmanned aircraft, remotely piloted systems, or autonomous operations that were drafted before the current regulatory framework existed. Brokers placing Specific-category risks should use wordings that have been purpose-built for RPAS or that carry explicit manuscript endorsements confirming RPAS coverage.

The policy period must align with, or exceed, the OA validity period. Where an OA is granted for a multi-year term, a short-period policy creates a Paragraph 6 compliance gap at renewal. Some underwriters will issue a certificate of currency that references the OA number directly; this is best practice and simplifies CAA correspondence.

Limits should be set by reference to the retained EU Regulation 785/2004 SDR minima as a floor, with the actual limit determined by the operator's contractual obligations, the nature of the overflown area, and any client-imposed requirements. Brokers should document the limit-setting rationale in the file — regulators and courts will both scrutinise whether the limit was adequate for the stated operation if a claim arises.

Broker Workflow for Paragraph 6 Submissions

The most efficient submissions reach the underwriter before the operator submits their OA application to the CAA, not after. The CAA's processing timeline means that an operator who applies for an OA without confirmed insurance terms may face a gap between authorisation grant and operational start. Brokers who position themselves as part of the pre-application process — rather than a post-approval formality — add measurable value and reduce the risk of last-minute coverage disputes.

A complete submission pack for a Paragraph 6 risk should include the draft or current OA (or the ConOps if the OA is not yet issued), the operator's risk assessment or SORA documentation, the aircraft technical specification, the maintenance and crew qualification records, and a completed proposal form that addresses BVLOS, payload, and geographic scope explicitly. Incomplete submissions are the primary cause of underwriter requests for further information, which extend the quote timeline.

Once terms are agreed, the broker should obtain a policy schedule and, where the underwriter offers it, a Paragraph 6 compliance letter or certificate referencing the OA number. This document should be retained by the operator alongside the OA itself and made available on request to the CAA, to clients, and to any relevant landowner or airspace authority.

• Obtain draft ConOps or current OA before approaching market
• Compile aircraft spec sheet, MTOM confirmation, and payload manifest
• Gather crew licences, GVC or equivalent qualification evidence
• Include SORA or risk assessment documentation
• Confirm geographic scope, including any overwater or international legs
• Request Paragraph 6 compliance letter from underwriter at bind

2026 Market and Regulatory Signals

The CAA's ongoing development of the UK SORA framework and its engagement with EASA's SORA 2.0 methodology are likely to influence how OA conditions — including Paragraph 6 — are drafted for new and renewed authorisations. Operators and brokers should monitor CAA publications and the UK Airspace Modernisation Strategy for changes to the Specific-category risk assessment process that may alter the insurance conditions attached to OAs.

The growth of drone-as-a-service contracts, particularly in infrastructure inspection, precision agriculture, and public-safety applications, is increasing the frequency of client-imposed insurance requirements that exceed the Paragraph 6 minimum. Brokers should treat the OA insurance condition as the regulatory floor and the client contract as the commercial ceiling — and ensure the policy satisfies both simultaneously.

Capacity in the specialist RPAS market has broadened since the early years of the Specific category, but underwriters remain selective on BVLOS, urban air mobility precursor operations, and high-value autonomous platforms. Operators planning significant operational changes — new aircraft types, extended geographic scope, or transition from VLOS to BVLOS — should engage their broker and underwriter well ahead of the OA variation application, not as an afterthought.

Frequently asked questions

What does Paragraph 6 of a CAA Operational Authorisation cover?

Paragraph 6 is the insurance condition within a CAA Specific-category Operational Authorisation. It requires the operator to maintain third-party liability insurance that is appropriate to the operation described in the OA and that meets the minima set by retained EU Regulation 785/2004, which scales required limits by aircraft MTOM. The condition is a continuing obligation — if the policy lapses or is materially restricted, the OA is simultaneously at risk of suspension.

Which operations require a CAA Operational Authorisation and therefore trigger Paragraph 6?

Any commercial drone operation in the UK Specific category that cannot be conducted under a standard scenario (STS-UK-01 or STS-UK-02) or an approved pre-defined risk assessment (PDRA) requires a bespoke OA. This includes most BVLOS operations, flights over or near congested areas beyond STS limits, operations with aircraft above the Open-category MTOM ceiling, and any operation where the CAA's risk assessment process determines that standard scenarios do not adequately mitigate the risk.

Can a standard commercial liability policy satisfy Paragraph 6?

Rarely. Standard commercial liability wordings frequently exclude unmanned aircraft, remotely piloted systems, or autonomous operations. A Paragraph 6-compliant policy must use a wording purpose-built for RPAS or carry explicit manuscript endorsements confirming that the policy responds to the specific operation, aircraft, and geographic scope in the OA. Brokers should verify that no exclusion in the policy carves out the activities described in the authorisation before binding.

What information does a broker need to place a Paragraph 6-compliant programme?

A complete submission should include the draft or current OA or ConOps, the operator's SORA or risk assessment documentation, the aircraft technical specification and MTOM confirmation, payload details, crew qualification evidence (including GVC or equivalent), maintenance records, and a clear statement of geographic scope. BVLOS operations additionally require details of the detect-and-avoid solution and communications architecture. Incomplete submissions are the primary cause of extended quote timelines.

What happens to the Operational Authorisation if the insurance policy is cancelled mid-term?

Paragraph 6 creates a continuing obligation, so a mid-term cancellation, voidance, or material restriction of the policy places the OA in breach of its conditions. The CAA may suspend or revoke the authorisation. Operators should ensure their policy includes a notification clause requiring the insurer to inform the CAA of any cancellation, and brokers should monitor renewal dates carefully to avoid inadvertent gaps, particularly where OA validity periods extend beyond a standard annual policy term.

How does the broker workflow differ for a Paragraph 6 renewal versus a new OA application?

For a new OA application, the broker should ideally confirm insurance terms before the operator submits to the CAA, so that the OA is not granted with a gap before coverage is in place. For a renewal, the broker should review any changes to the OA conditions — particularly if the CAA has updated the operational limitations or the aircraft has changed — and ensure the renewed policy reflects those changes. In both cases, obtaining a Paragraph 6 compliance letter or certificate referencing the OA number is best practice.
