Guidewire calls for data-centric London Market to replace PDF workflows

Passing unstructured PDFs and fragmented documents between brokers, underwriters and internal systems has become more than an irritation in the London Market. At Guidewire’s European Guidewire Insurance Forum 2026, the London Market Update breakout treated that habit as a strategic bottleneck, because every rekey, copy-and-paste and handoff slows placement, weakens data quality and keeps automation out of reach. The panel, which Guidewire framed around AWS, Big Ticket and its own market specialists, argued that the market cannot keep pretending document handling is the same thing as data exchange.

The practical cost shows up inside underwriting teams. Underwriters still spend a meaningful part of the day pulling information out of market reform contracts and entering it into multiple systems, a repetition Guidewire described as an administrative tax. That matters most in complex, data-heavy business, where the notes say about 31% of growth is concentrated and where speed and accuracy decide who gets the placement. Guidewire’s 2026 London Market Tech Barometer sharpened the point: 78% of respondents said an insurer’s technological capability is either a very significant competitive advantage or the deciding factor when placing business.

The answer on offer is not another layer of document management software. Guidewire pointed to the Core Data Record and the Intelligent MRC, also called MRC v3, as the structure the market needs if it wants to capture information once at source and let it move through the chain without repeated human intervention. The London Market Group Data Council published Core Data Record v3.2 and a refreshed Market Reform Contract v3 on March 29, 2023, and Lloyd’s says the LIMOSS Market Business Glossary is the central source for business definitions, standards and reference data. Velonetic describes MRC v3 as a structured contract that allows accurate, ACORD-standardised data to flow through the insurance transaction lifecycle with minimal human intervention. Early-adopter brokers were already using MRC v3 in late 2023.

That shift is bigger than efficiency. Guidewire’s case is that structured data is the precondition for algorithmic underwriting, where systems can handle risk triage, validation and basic analysis while humans focus on the difficult cases. McKinsey’s recent insurance AI coverage backs that logic, noting that insurers are already using AI across underwriting, claims, customer service and back-office functions, but that technical capability and data issues remain critical. In other words, the market cannot bolt AI onto PDFs and expect it to scale.

The timing is unforgiving. The London Market Group said in February 2026 that the market’s overall share rose to 8.7% in 2024, and that London remains larger at $187bn than all other global insurance hubs combined. That scale makes the cost of friction obvious. If the London Market wants to protect its edge in specialty lines, it needs brokers and carriers to reward structured exchange, not document shuffling, and to treat data standards as core market infrastructure rather than a nice-to-have.
