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.^[1][2] and its head office at 1 Bartholomew Lane in London.^[3] The Horsham building, St Marks Court is earmarked as developable.^[4] In an external recess, to the market place (Carfax) side, is the tall spired tower of the church.^[5] Its nave was demolished in about 1985.^[5] The spire was part of the original church of 1841 constructed from sandstone. The tower's base has become a florist and volunteers’ centre.^[5]

Sun Alliance went on to acquire the London Assurance Company in 1965 (becoming Sun Alliance & London)^[6] and Phoenix Assurance in 1984.^[6] The company thus added suffix "Group" in 1989, consolidated most UK-based operations into the Horsham office in 1990,^[7] and yet kept its London head office.^[8] The company merged with Royal Insurance to form the Royal & Sun Alliance Insurance Group in 1996.^[9]
