SVB Holding's distribution companies will generate £20m more gross written premium income than forecast for 2002.
SVB has upped its forecast from £60m at the end of 2001 to £80m.
Fusion Insurance Services, which is 80% owned by SVB, has become the most significant source of income, with high quality regional commercial business.
Fusion is forecast to write more than £50m in premium income this year.
SVB Underwriting Services and SVB Asset Protection, which are wholly-owned, will account for the rest of the money.
SVB chief executive Rupert Villers said he was extremely pleased with the growth of the channels.
