Drone Hull Agreed Value vs Market Value UK
Written by the UK Drone Insurance editorial team · reviewed by Anton Kuznetsov, founder
When you submit a hull schedule for a commercial drone programme, the valuation basis you choose determines whether a total-loss settlement covers your actual exposure or leaves a gap. Agreed value and market value produce materially different claims outcomes, and for most commercial UAS operators in the UK, agreed value is the only basis that reflects real replacement cost. This page explains the mechanics of each basis, the UK regulatory context that makes valuation basis a compliance question, what drives premium on an agreed-value hull, and what your broker needs to bind cover correctly.
What agreed value and market value actually mean on a hull policy
An agreed-value policy fixes the insured sum at inception. If the aircraft is written off, the insurer pays that agreed figure — subject to policy conditions — without applying a depreciation calculation at the point of claim. The value is negotiated, documented, and locked in before the risk attaches.
A market-value policy pays what the aircraft was worth immediately before the loss. The insurer appoints an assessor who references second-hand sale data, age, hours flown, and condition. For a two-year-old survey drone that has been meticulously maintained and carries a full sensor payload, the assessor's figure and your replacement cost are rarely the same.
The gap between the two bases is widest for aircraft that depreciate quickly on paper but retain high operational value — multi-rotor inspection platforms, LiDAR-equipped fixed-wings, and purpose-built cinematography rigs all fall into this category. It is also wide for aircraft that have appreciated because the manufacturer has discontinued the model or raised prices since your purchase date.
Agreed value eliminates the assessor's discretion at the point of total loss. That certainty is the core commercial reason operators and their clients prefer it — and why we do not offer market-value hull cover on this programme.
UK regulatory framework: weight categories, authorisation routes, and insurance implications
The UK CAA structures UAS operations under three categories — Open, Specific, and Certified — governed by the Air Navigation Order and CAP 722. Within the Open category, three sub-categories define where and how you may fly based on aircraft mass: A1 permits flight with aircraft under 250 g in proximity to uninvolved people; A2 permits closer flight with aircraft under 2 kg carrying a C2 class mark or equivalent; A3 permits flight up to 25 kg maximum take-off mass in areas away from people. Once an operation exceeds any of those sub-category limits — by mass, proximity, or flight mode — it moves into the Specific category and requires a CAA Operational Authorisation.
Within the Specific category, operators access authorisation through one of two routes. A Pre-Defined Risk Assessment (PDRA) applies where the operation matches a scenario the CAA has already assessed and published; the operator self-declares compliance and applies for the corresponding OA. A bespoke Operational Authorisation requires the operator to submit a full Specific Operations Risk Assessment (SORA), which the CAA evaluates individually. BVLOS operations, flights over crowds, and operations with heavier or more complex aircraft typically require the bespoke SORA route.
The competency credential underpinning Specific category eligibility in the UK is the General Visual Line of Sight Certificate (GVC), which replaced the legacy Permission for Commercial Operations (PfCO) under the CAA's domestic framework. The GVC is issued by CAA-approved National Qualified Entities and is the standard qualification the CAA expects to see on an Operational Authorisation application. This is a UK domestic route under the ANO and CAP 722 — it is not connected to EASA's Article 16 transitional mechanism, which applies in EU member states and has no direct equivalent in post-Brexit UK law.
The CAA does not prescribe a hull valuation basis in its Operational Authorisation conditions. However, authorisation conditions require operators to demonstrate that insurance arrangements are adequate for the declared operation. Client contracts and site-access agreements issued by infrastructure owners, utilities, and public authorities frequently go further and specify minimum hull cover levels — a market-value policy that cannot guarantee a minimum settlement figure will not satisfy those contractual requirements.
Why depreciation makes market value unsuitable for commercial UAS
Consumer-grade airframes depreciate steeply in their first twelve months. Commercial operators often carry those same airframes on their balance sheet at original purchase price because the sensor suite, custom firmware, or integration work attached to the platform represents the real capital outlay. A market-value settlement strips out that integration premium — the assessor prices the bare airframe against comparable second-hand listings, not your actual replacement cost.
Payload is the clearest illustration. A thermal imaging sensor or multispectral camera mounted on a mid-range airframe can exceed the airframe's own value. Under a market-value policy, the hull section covers the airframe; the payload may sit under a separate equipment clause with its own valuation basis. If those two clauses are not aligned, a single crash produces two separate shortfalls. Agreed value, applied to the combined hull-and-payload schedule, eliminates that misalignment.
Operators working under a Specific category Operational Authorisation are often required by their client contracts to demonstrate that hull cover is adequate for the declared asset value. A market-value policy that settles below the declared value creates a contractual exposure that sits entirely with the operator.
What drives the cost of agreed-value hull cover
Premiums on agreed-value hull programmes are quoted in GBP and scale with a combination of factors — no single variable dominates, and underwriters assess them in combination. Understanding the cost shape helps operators structure their submission to reflect genuine risk rather than inadvertently triggering loading.
BVLOS status is the single largest upward driver. An aircraft authorised for beyond visual line of sight operations presents a materially different ground-risk and air-risk profile from a VLOS platform, and underwriters price that difference explicitly. Operating environment matters similarly: urban and peri-urban environments, confined industrial sites, and operations over infrastructure attract closer scrutiny than open rural survey work.
The payload-to-airframe value ratio affects how underwriters assess the total agreed value. Where payload significantly exceeds airframe value, underwriters want to understand how the payload is secured, whether it is interchangeable across multiple hulls, and whether it carries its own manufacturer warranty. Operator claims history — both frequency and severity — influences both premium and deductible structure; deductibles typically rise on autonomous or BVLOS operations. Fleet size affects programme structure but not necessarily per-unit cost in a linear way; a well-managed fleet with consistent maintenance records can present a more favourable risk profile than a smaller fleet with gaps in documentation.
Typical exclusions on UK UAS hull wordings — what agreed value does not cover
Agreed value fixes the settlement amount on a covered loss — it does not expand the scope of cover. Operators should read the exclusions section of any hull wording carefully before binding, because several common exclusions can defeat a claim regardless of the agreed-value basis.
Standard exclusions on UK UAS hull wordings typically include wear and tear and gradual deterioration, manufacturer defect or design fault, and damage arising from failure to follow the manufacturer's operating limitations. Flyaway events — where the aircraft departs controlled flight and is not recovered — are frequently subject to a specific condition requiring telemetry evidence to confirm the loss was not operator-induced or the result of a pre-existing fault. Without downloadable flight logs or telemetry data, a flyaway claim can be declined even on an agreed-value policy.
Operators should also check whether the wording excludes losses arising from flight outside the scope of the CAA Operational Authorisation — for example, a VLOS-only aircraft flown BVLOS, or an operation conducted in a category for which the operator does not hold the required competency credential. These are not hypothetical exclusions; they are the most common grounds on which hull claims are contested.
- Wear and tear and gradual deterioration
- Manufacturer defect or design fault
- Flyaway without telemetry or flight-log evidence
- Operation outside the scope of the CAA Operational Authorisation
- Failure to comply with manufacturer operating limitations
- Damage caused by an operator not holding the required competency credential (e.g. GVC for Specific category operations)
Broker submission workflow: documents, formats, and turnaround
Agreed-value hull is a specialty line that sits within the Lloyd's and London company market. Brokers placing this cover should use a UAS-specific proposal form that captures operational category, BVLOS status, flight environment, and payload configuration — not a generic aviation hull form adapted for drones. The submission pack should be assembled in PDF format with a covering note that states the agreed-value basis explicitly and references the operator's CAA Operator ID and, where applicable, their Operational Authorisation reference number.
For each hull, the submission should include a current manufacturer invoice or replacement quotation, an itemised payload schedule listing each component by serial number and individual value, and a maintenance log summary confirming airworthiness status. Where the declared value exceeds the manufacturer's current list price — because of custom integration, discontinued components, or embedded software licensing — a brief technical note from the operator or their approved maintenance provider should accompany the submission. The agreed value is signed off by the lead underwriter at inception; it is not a figure the broker sets unilaterally.
For standard VLOS Specific category programmes with a clean claims history and complete documentation, a bindable indication is typically available within one working day of a complete submission. BVLOS programmes, bespoke SORA-backed operations, or fleet schedules with complex payload configurations require additional underwriting review and should be submitted with a longer lead time — allow at least three to five working days for a first indication, and more if the SORA documentation is still in draft.
At renewal, the broker's role is to prompt the operator to review and update each hull's agreed value. There is a natural operator tendency to hold values flat to contain premium. The broker's obligation is to document that the operator has been advised of the under-insurance risk and has made an informed decision — not simply to renew at last year's figures without a conversation.

Frequently asked questions
- Does agreed-value hull cover include the payload, or is that a separate section?
- It depends on how the policy schedule is structured. Some UAS hull wordings treat the airframe and permanently attached payload as a single agreed value; others schedule payload separately under an equipment or contents section with its own valuation basis. Before binding, confirm with your broker that the agreed value on the hull section includes all payload components you intend to cover, and that each item is listed by serial number. A mismatch between hull and payload valuation bases is one of the most common sources of claims shortfall on commercial drone policies.
- Which operators are eligible for agreed-value hull cover in the UK?
- Eligibility is determined by the underwriter. In practice, agreed-value hull is available to operators holding a valid CAA Flyer ID and Operator ID, whether they fly under the Open category sub-bands (A1, A2, or A3) or under a Specific category Operational Authorisation obtained via a PDRA or bespoke SORA route. Operators pursuing BVLOS authorisations are typically required to carry agreed-value hull as a condition of the programme. Eligibility is also influenced by the operator's claims history, the nature of the operations, and the declared operating environment.
- What triggers a requirement to update the agreed value mid-term?
- Most hull policies contain a material-change notification clause. Where that clause is drafted as a condition precedent, failure to notify before the change occurs can give the insurer grounds to decline the claim entirely. Where it is a condition subsequent, the insurer's remedy is more limited but a reduction in settlement remains possible. Either way, operators should notify their broker promptly when adding a new high-value payload, completing a major modification, or discovering that the manufacturer has substantially increased the list price of a replacement unit. Brokers should build a mid-term review prompt into their account management process, particularly for operators who upgrade payloads frequently.
- How does the CAA's Specific category affect hull insurance requirements?
- The Specific category covers operations that exceed Open category limits — including BVLOS flights, operations in proximity to people beyond A1 or A2 permissions, and aircraft that exceed the 25 kg A3 sub-category ceiling. A Specific category Operational Authorisation is required, obtained either via a PDRA for standard scenarios or a bespoke SORA for more complex operations. The CAA's authorisation conditions do not prescribe a hull valuation basis, but they require the operator to demonstrate that insurance arrangements are adequate for the declared operation. Client contracts and site-access agreements frequently go further and specify minimum hull cover levels that a market-value policy cannot reliably satisfy.
- Can a broker place agreed-value hull cover for a mixed fleet spanning Open and Specific category aircraft?
- Yes. A single fleet programme can schedule aircraft operating across multiple CAA regulatory categories, provided the proposal form captures the operational category and authorisation status for each hull. Underwriters assess the risk profile of each aircraft individually — BVLOS-authorised aircraft and those operating under bespoke SORA conditions will attract closer scrutiny and may require more detailed documentation. The agreed value for each hull must be stated separately; a single blended fleet value is not acceptable on a properly structured agreed-value programme.
- What happens if a total-loss claim is disputed on valuation grounds?
- On a correctly worded agreed-value policy, the insurer has accepted the declared value at inception and cannot reopen the valuation question at the point of a total-loss claim — provided the operator has complied with all policy conditions, including material-change notification obligations. If a dispute arises, the broker's first step is to produce the policy schedule and the agreed-value declaration to demonstrate that the basis was explicitly agreed at inception. If the wording is ambiguous, engage a specialist aviation claims advocate at the earliest opportunity. This is precisely why wording clarity at inception matters: a disputed valuation basis is far harder to resolve after a loss than before it.
