We’ve expanded our PI excess layer offering with AmTrust

We have further expanded our PI offering, with capacity from AmTrust now available for standalone excess layer policies and more flexible multi-layer placements.

The development gives brokers greater choice when arranging PI cover requiring higher limits, with the option to access AmTrust capacity for an excess layer without the primary policy needing to be placed through us.

We can also now offer multiple excess layers, combining capacity across our partners AmTrust, Hadron and Accelerant. This gives brokers more options when structuring larger or more complex PI placements, while retaining the benefit of working with a single NBS underwriting team.

Supporting larger PI placements

The expanded facility means we can support brokers in a number of different ways, whether they require a standalone excess layer or are looking to build cover across multiple layers.

For brokers, the key benefits include:

  • Access to higher overall indemnity limits
  • More options when structuring complex placements
  • The ability to secure multiple layers through our capacity partners
  • A single underwriting team managing multiple elements of the placement
  • Reduced placement complexity and improved turnaround times
  • Greater consistency in underwriting approach across layers

Building on our expanded PI capacity

This latest development builds on the expansion of our relationship with AmTrust announced earlier this year.

In June, we introduced an additional £5 million excess layer backed by AmTrust, enabling us to offer PI placements with total limits of up to £10 million when combined with £5 million of primary capacity supported by Hadron or Accelerant.

The introduction of standalone excess layer policies and the ability to offer multiple excess layers gives brokers further options when approaching us for PI business, particularly where clients require higher limits or a more tailored placement structure.

Our PI underwriters are available to discuss individual placements and help brokers explore the most appropriate structure for their clients.
