Sun Alliance Group plc was a large insurance business with its main offices in the City of London and later Horsham. In 1996 Sun Alliance merged with Royal Insurance to form the Royal & Sun Alliance Insurance Group.

History

The company was created in 1959 by the merger of Sun Insurance, founded in 1710, and Alliance Assurance founded in 1824. [1]

In the mid-1960s Sun Alliance established its administrative centre in a large office block, spanning an A-road through the town centre of Horsham, a railway town 31 miles (50 km) south of London's centre. [2] [3] and its head office at 1 Bartholomew Lane in London. [4] The Horsham building, St Marks Court is earmarked as developable. [5] In an external recess, to the market place (Carfax) side, is the tall spired tower of the church. [6] Its nave was demolished in about 1985. [6] The spire was part of the original church of 1841 constructed from sandstone. The tower's base has become a florist and volunteers’ centre. [6]

Sun Alliance went on to acquire the London Assurance Company in 1965 (becoming Sun Alliance & London) [7] and Phoenix Assurance in 1984. [7] The company thus added suffix "Group" in 1989, consolidated most UK-based operations into the Horsham office in 1990, [8] and yet kept its London head office. [9] The company merged with Royal Insurance to form the Royal & Sun Alliance Insurance Group in 1996. [10] [11]
