Fortis will broaden its commercial lines offering in 2006 as part of its continuing growth strategy.
Announcing the insurer's 2005 results, Fortis chief executive Barry Smith said the company would look for new ways to grow organically.
"We will look to develop new products to give brokers and intermediaries a wider choice of products," he said.
Those products would primarily be in personal lines, but Smith said there was scope to move into "small retail commercial".
Fortis delivered profit before tax growth of 18% to £58.1m, up from £49.2m a year earlier. Gross written premium (GWP) also climbed by 4% to £596.6m from £574m a year earlier.
Steady growth in 2006 is expected to be underpinned by the insurers' win of Age Concern's household business, which went live in February.
In Fortis' affinity business, Smith said the bedding in of two major acquisitions - OutRight in September 2005, and Affinity Solutions in January - would be a "priority" in the next year.
