The Fidelis Partnership has appointed Peter Williams as chief underwriting officer and Gary McInally as managing director and chief executive of Pine Walk Capital Limited, subject to regulatory approval, strengthening centralized oversight across a platform that has grown from an MGA incubator into one of the London market's more significant delegated underwriting operations.
Williams will oversee underwriting across Pine Walk's 18 MGAs and take responsibility for cross-selling between Pine Walk's individual businesses and the wider Fidelis Partnership. McInally, who previously served as chief project actuary at TFP and was directly involved in building both the group and the Pine Walk platform, takes over operational and governance leadership.

Pine Walk generated US$1.2 billion in written premium in 2025 and now supports US$1.6 billion across its MGA businesses, which span specialty classes including international casualty, accident and health, surety and credit risk. Delegated underwriting accounts for approximately 45% of Lloyd's premium income, or around US$26.2 billion annually, making the quality of central oversight across platforms of this scale a market-wide concern rather than a firm-specific one.
The appointments arrive at a point in the cycle where the pressure on MGAs has shifted. MGAA chief executive Michael Keating has warned publicly that underwriting discipline is becoming increasingly important as pricing falls while claims costs remain elevated - a combination that erodes the margin for error that rising rates had previously provided.
For a platform with 18 individual underwriting businesses operating across different specialty classes, that environment makes the balance between entrepreneurial autonomy and centralized oversight more consequential. Williams's remit to oversee underwriting discipline across all 18 MGAs while simultaneously supporting cross-selling coordination with TFP addresses both sides of that balance directly.
The cross-selling mandate is the more forward-looking of the two functions. TFP's underwriting model evaluates opportunities across business lines rather than solely within individual portfolios, using cross-selling to identify additional products that address the same risk across the group's broker and client relationships. Williams now has direct oversight of how that coordination operates across Pine Walk's book - a structural change that has practical implications for how reinsurance brokers structure multi-class submissions involving Pine Walk MGAs.
Pine Walk has expanded meaningfully in the past 18 months. The Sevanta international casualty MGA was launched as part of that build-out, alongside additions in accident and health, surety and credit risk. The platform gives its underwriting teams access to group-wide broker and client relationships alongside capacity, technology and operational support from TFP.
Williams joins from SCOR, where he held specialty underwriting and leadership roles. He said Pine Walk's combination of entrepreneurial underwriting with centralized infrastructure and governance was the specific attraction. McInally said the platform's collaborative model is reflected in the growth it has achieved, and that his focus will be on leading it through the next stage of development in his new role.
For reinsurance brokers with capacity placed across TFP's operations, the structural signal here is worth noting. Williams's cross-selling remit means Pine Walk's individual MGA businesses are now more explicitly connected to TFP's group-wide broker relationships than they were under the previous structure. That coordination sits under dedicated leadership for the first time.
For brokers evaluating Pine Walk as a capacity destination in the current soft market, the appointment of a dedicated CUO with explicit responsibility for underwriting discipline across all 18 MGAs is the governance signal that matters. A platform at US$1.6 billion and growing, operating across a wide spread of specialty classes in a softening rate environment, carries meaningful accumulation and correlation risk. Centralized underwriting oversight is the mechanism for managing that - and it now has a named, experienced leader accountable for it.
