Phoenix Assurance or Phoenix Fire Office was a fire insurance company founded in 1680 in England.
The history of the company includes the nostalga of red-coated attendants clattering to the fires of London on horse-drawn tenders.
The Phoenix figured in Case Law. In 1796, the company refused to pay damages awarded of £3,000 (2011: £240,000) following a 1792 fire at a house in Tavistock Street, London. Phoenix claimed that the owners had failed to obtain a Certificate from the ministers and churchwardens of the parish affirming the good character of the victims. Phoenix issued a Writ of Error to appeal the original decision.
Sun Alliance & London acquired Phoenix Assurance in 1984.
