THREE PART SERIES FOR THE LLOYD’S MARKET
Proof, Not Attestation — Meeting Lloyd's Principle 4
Part 1: What Lloyd's Now Requires of Claims
The regulatory shift, and what each of the six Claims Management sub-principles requires you to evidence.
By Ilda Cairns, Chief Product Officer, VCA Software
01. Executive Summary
Lloyd’s did not change what good claims management looks like. It changed what Managing Agents, TPAs and Coverholders must now do about it: prove it, not simply attest to it.
On 1 January 2026, Lloyd’s made Claims Management a hurdle Principle. Under Principles-Based Oversight, no syndicate can be categorised above its weakest hurdle — so claims performance now feeds directly into categorisation, capital treatment and member returns. The Managing Agents who come out ahead will not necessarily be the ones doing the best claims work. They will be the ones who can prove it — on demand, at portfolio scale, against the standard that governed the work at the time.
Most organisations in this market already manage claims well. What has changed is what they are asked to show. Lloyd’s Principle 4 defines what good claims management looks like in broad, outcome-based language; it does not prescribe how to measure it. Each Managing Agent has to decide for itself which KPIs evidence compliance, and then produce the data to prove it, repeatedly and at portfolio scale.
And there is a deeper point underneath that. The harder part is not producing more claims data; it is making sure the data is read against the right version of the standard that applied at the time — the claims strategy, reserving philosophy, authority framework, SLA package and delegated authority requirements that were in force when the work was actually done. In practice, Principle 4 is not proven by claims data on its own. It is proven by claims data connected to the operating standards that governed the work, with a clear record of who owned them and when they changed.
This VCA Software white paper translates each of Lloyd’s six Claims Management sub-principles into measurable, operational KPIs and the governing standard each must be measured against, explains why process-embedded assurance — not individual expertise alone — is what evidences compliance, and shows how VCA’s platform delivers native reporting against every sub-principle.
VCA Software has operated within the Lloyd’s market for over a decade, serving Managing Agents, TPAs and Coverholders across the UK, US, Canada and Australia. This framework is built on direct market experience and a close reading of Lloyd’s published revisions to Principle 4 (November 2024) and the accompanying Maturity Matrix guidance, together with current market guidance including the LMA’s AI Adoption Toolkit (April 2026), produced in partnership with Barnett Waddingham.
02. Why Claims Management Is Now a Hurdle Principle
The shift from aspiration to obligation
For years, claims quality was treated as a reputational concern at Lloyd’s — important, but not structurally enforced. That changed on 1 January 2026, when Lloyd’s formally elevated Claims Management to the fifth hurdle Principle under its Principles-Based Oversight (PBO) framework, sitting alongside Underwriting Profitability, Reserving, Governance/Risk Management/Reporting, and Culture.
Under PBO, no syndicate can be categorised higher than its lowest-rated hurdle Principle. A syndicate with strong underwriting results but a Below Expectations rating on Claims Management is constrained accordingly. Marginally Below caps the syndicate at MODERATE; Below caps at UNDERPERFORMING; Well Below caps at UNACCEPTABLE. Put plainly, under Principle 4 a syndicate is now only as strong as the claims evidence it can show.
"Syndicate ratings will be directly influenced by claims handling performance. Failure to meet expectations may lead to a range of consequences, including restrictions on underwriting and increased regulatory oversight. However, high performers can expect to see their maturity ratings and market reputation strengthened."
The Maturity Matrix is not uniform
Lloyd’s Maturity Matrix describes four levels — Foundational, Intermediate, Established and Advanced — but the levels apply differently to each sub-principle. This is important for how Managing Agents should read their own compliance position:
- Sub-principles 1 and 6 have a single Foundational level. They apply universally to every Managing Agent regardless of size or materiality.
- Sub-principles 2 and 3 added an Advanced level in the 2024 revision, raising the ceiling for material syndicates.
- Sub-principles 4 and 5 retain the four-level structure. Material syndicates with significant claims exposure are expected to operate at Established or Advanced.
Critically, Lloyd’s has stated that syndicates at Advanced maturity must demonstrate not only that benchmarks are met, but that the business is continuously improving. This requires ongoing data and review cadence — and the ability to trace performance back to the standards in force at the time the claim activity occurred — not a one-time attestation.
The cascading effect beyond syndicates
While Principle 4 is formally a regulation for Managing Agents, its effects cascade directly to TPAs, Coverholders and Independent Adjusters operating under delegated authority arrangements. Managing Agents are now required to hold their delegated claims handlers to the same standard — and evidence that oversight with data.
Sub-principle 5 explicitly requires that delegated claims handling services are delivered consistently and effectively, aligned to the Claims Management Strategy. In practical terms, this changes what a Managing Agent needs from its delegated handlers. A TPA or Coverholder that can produce clean compliance reporting makes its Managing Agent’s oversight easier to evidence and strengthens the relationship. One that cannot leaves a gap the Managing Agent has to account for, and those arrangements can be expected to come under closer review.
Where brokers and capital sit in the chain
Two parties sit either side of this obligation. Above the Managing Agent are the syndicate’s members — the capital providers. They do not handle claims, but they carry the consequence: a weak Principle 4 rating caps syndicate categorisation, which drives capital treatment and, in turn, member returns. That is what makes claims compliance a board and capital concern, not only an operational one. Alongside sits the Broker — the placement and claims-notification conduit through which business and claims data enter the market. Brokers are not a Principle 4 obligated party; the obligation rests with the Managing Agent and cascades only to delegated claims handlers under Sub-principle 5. But the quality and timeliness of the evidence a Managing Agent can produce depends in part on that broker chain, which is why claims infrastructure that captures clean, structured data from first notification serves the whole chain — not the handler alone.
03. The Six Sub-Principles — and What They Actually Require
Lloyd’s Principle 4 is structured around six sub-principles, and the wording is deliberately high-level. Lloyd’s is an outcomes-based regulator, not a prescriptive one. That gives Managing Agents room to work in a way that suits their book, and it hands them a real question at the same time: each has to decide what evidence of compliance actually looks like in practice.
For each sub-principle below, we look at what it is really asking for, then set out the data and reporting needed to evidence it. We also name the governing standard that has to sit behind that data, because this is where compliance is won or lost. Without the standard, KPI reporting is just a more sophisticated form of marking your own homework. With it, the same reporting becomes evidence that holds up.
Sub-Principle 1 — Claims Management Integrated into the Business Plan
Lloyd’s requires that claims information and knowledge is available and used pre-emptively in business planning and wider syndicate performance management. Claims is to be addressed explicitly within the Syndicate Business Plan and medium to long-term business strategy.
In operational terms, claims performance must be tracked against plan targets — and claims insight must feed forward into underwriting and business planning, not merely be reported backward. This includes risk alerts on emerging exposures, moral and morale hazards, and outliers such as denials, litigation, subrogation, and salvage that may indicate portfolio drift.
Required data: SLA performance vs. plan targets; claims volume vs. forecast; cycle time trends against business plan commitments; risk-alert notifications to underwriting; outlier tracking against plan; cost per claim vs. budget.
Governing standards: business plan targets; contractual SLA definitions; outlier definitions; feedback-loop triggers — each formally owned, documented and current.
Sub-Principle 2 — Appropriate Resource and Expertise
Managing Agents must demonstrate that appropriate resource and expertise is in place to consistently deliver against the Claims Management Strategy, including a documented method to measure, monitor and maintain resource adequacy. The 2024 revision added an Advanced level to this sub-principle — meaning material syndicates are now expected to operate dynamic, stress-tested resource models.
This is frequently underestimated. It is not enough to have sufficient headcount: syndicates must evidence workload monitoring, capacity utilisation, service quality, surge and catastrophe response capability, and the validity of handler authority and licensing on a per-claim basis.
Required data: claims handler workload ratios; average time-to-assign at FNOL; capacity utilisation including surge / catastrophe; quality scores per handler; authority and licensing validation; training and competency refresh currency.
Governing standards: handler authority framework; licensing rules; competency model; surge and catastrophe staffing assumptions for the book.
Sub-Principle 3 — Proactive Claims Management and Infrastructure
Lloyd’s requires that proactive claims management is delivered, supported by infrastructure appropriate to the size and complexity of the business. The word “proactive” is significant. Reactive claims handling — responding only when prompted — is no longer sufficient. Systems must enable early intervention, flag developing claims before they escalate, and support structured lifecycle management.
The 2024 revision moved third-party experts (loss adjusters, lawyers, forensic accountants) into this sub-principle as part of proactive delivery. Managing Agents must now evidence the performance and oversight of their expert panels alongside their own handlers — and operate within the Lloyd’s Claims Lead Arrangements (LCLA) where applicable.
A point worth being explicit about: “early intervention” and “complex claim” are not generic terms. Each Managing Agent must define its own triggers — for example, severity thresholds, line-of-business indicators, or specific claim characteristics — and evidence that the system applies them consistently, with the definitions documented, owned and version-controlled rather than left to informal handler judgement.
Required data: average FNOL-to-resolution cycle time; early intervention rate on complex claims (with defined triggers); claim re-open rate; escalation response times; time since last activity; third-party expert performance metrics; litigation, referral and complaint volumes.
Governing standards: complex-claim triggers; early-intervention thresholds; escalation and inactivity rules; expert referral standards; LCLA requirements where applicable.
Sub-Principle 4 — Accurate and Timely Case Reserving
Managing Agents must maintain accurate and timely case reserving in line with the reserving philosophy, with reserving insights — including development potential — exchanged across the wider business. The 2024 revision added explicit reference to case-reserve tolerances and to reserving recommendations by third parties, and brought reserving obligations under the LCLA framework.
This is where claims operations and the actuarial and finance functions meet. For it to work, the claims system has to feed reserving data through in a timely, structured form, and flag developing trends as they emerge rather than after the fact.
Why leakage is the Keystone reserving KPI
Leakage — measured as ultimate incurred loss against initial reserve — is the Keystone metric of reserving discipline under Principle 4. It is also the reserving KPI least open to self-reporting, provided the governing context is locked. It emerges from lifecycle data the claims system has already captured, not from anything a handler or provider attests; and when the initial reserve, reporting date and aggregation basis are fixed and attributable, there is little left for a handler or provider to massage.
Leakage is only defensible, though, when the system can reconstruct the governing context: the initial reserve as confirmed, the reporting date, the reserving philosophy and tolerance thresholds in force, and any third-party reserving recommendation on the file at the time. Without that temporal context, leakage is a retrospective number. With it, leakage becomes structural evidence of reserving discipline.
Managing Agents who measure leakage, set tolerance thresholds, and review variance at executive level are not exposing weakness. They are demonstrating exactly the Advanced-level control Lloyd’s now expects — detailed case reserving measures that surface trends, themes, benchmarking and systemic issues, shared across the business with actuaries and underwriters. The risk runs the other way. In our experience, the Managing Agents who do not measure leakage are usually the ones who discover material under-reserving at year-end, when the options for putting it right are at their narrowest.
A second technical refinement worth noting: Lloyd’s-aligned reserving measurement is typically anchored to the claim reporting date rather than the claim event date. This matters operationally — claims with long reporting lags can distort event-date metrics in ways that obscure the underlying reserving discipline. Where leakage is measured, the defensible basis is indemnity cost — ultimate incurred against the initial reserve, aggregated per UMR — with a clear sign convention so that under- and over-reserving read consistently across the portfolio.
Required data: leakage ratio (ultimate vs. initial reserve); reserve adequacy against tolerances; frequency of reserve movements; average time from claim reporting date to initial reserve; dangling-reserve incidence (open claims without a confirmed reserve review within the SLA window); reserving insights exchanged with actuarial and underwriting.
Governing standards: reserving philosophy; initial-reserve confirmation rule; reserve tolerance thresholds; reserve review SLA; reporting-date logic; UMR aggregation logic.
Sub-Principle 5 — Delegated Claims Handling
Delegated claims handling services must be delivered consistently and effectively, aligned to the Claims Management Strategy. This is the sub-principle with the widest market impact: every Coverholder and TPA operating under a binding authority arrangement must now be monitored by their Managing Agent for compliance, against agreed standards, with appropriate escalation and challenge where expectations are not met.
Bordereau accuracy: who validates the validator?
A fair challenge to any claims platform that claims to evidence delegated authority compliance is this: how does the system prove its outputs are accurate, outside of audit? Self-reported bordereau accuracy is circular — a system marking its own homework. A defensible approach requires four things: pre-submission validation against the underlying claim records (not against the bordereau template alone); reconciliation against a source of truth that the delegated handler cannot edit; independent sampling that produces audit-trail evidence Lloyd’s assessors can interrogate; and version-pinned standards showing which authority limits, SLA requirements and reporting rules applied when the delegated handler acted.
What this means in practice is that delegated handling works best when handlers are not just submitting outputs for someone to check afterwards. The standards the Managing Agent has approved — authority limits, SLAs, reporting rules — should be delivered into the claims workflow itself, so that exceptions are caught before the bordereau is submitted rather than picked up later in audit.
Required data: bordereaux accuracy (validated, not self-reported) and timeliness; TPA SLA compliance scores; delegated authority exception reports; loss-ratio and reserve-development feeds from delegated providers; independent sampling and audit findings per handler.
Governing standards: authority limits; the Managing Agent’s SLA package; bordereaux and exception rules; market-reporting SLA — as in force at the time of handling.
Sub-Principle 6 — Governance and Oversight
Robust governance and oversight is required, including at executive level, to monitor and manage delivery of outcomes against expectations whilst identifying and realising opportunities for improvement. Like Sub-Principle 1, this sub-principle has a single Foundational level — it applies universally.
This is the capstone of the framework, and the most visible during Lloyd’s oversight assessments. Executive-level visibility requires real-time dashboards, exception reporting, and documented evidence that claims performance is regularly reviewed at board and senior management level — with a feedback loop into underwriting and actuarial, and a structured improvement framework that closes the loop on identified issues.
Dashboards alone, however, are not governance. Robust oversight requires named ownership of the definitions, thresholds and standards that drive the dashboards: who owns the definition of a complex claim, who owns reserve tolerances, who owns SLA standards, who approves changes, and how those changes reach the claims workflow. Executive review is stronger when it can show not only what the dashboard reported, but who owned the underlying standard, when it changed, and how compliance with it was tested.
Required data: executive KPI dashboard review cadence; escalation rate and resolution tracking; audit trail completeness; time to remediate identified gaps; feedback loop to underwriting and actuarial (insights actioned); continuous-improvement initiatives raised, owned and closed.
Governing standards: KPI definitions and named ownership; executive review cadence; escalation definitions; remediation ownership; change control for standards.
Conclusion
What the framework comes down to. Across all six sub-principles, Principle 4 rewards the same thing: claims work that can be evidenced against the standard that governed it, on demand and at portfolio scale. The Managing Agents who categorise well will not necessarily be the ones doing the best claims work today — they will be the ones who can prove it tomorrow, consistently, without a fire drill at year-end.
The rest of the series. This paper covered what Lloyd’s requires. Part 2, From Requirement to Proof, maps each sub-principle to the reporting that evidences it and examines where the obligation bites hardest in delegated authority. Part 3, Becoming Evidence-Ready, sets out a practical path and the platform capabilities that support it.
