Edward Moore and Sons: The company was formed by Edward Moore who began to practice as a "public accountant" at East India Chambers, Leadenhall Street from 1866 as 'Moore and Wallis's Mercantile Agency'. In 1880 Edward Cecil Moore was made a partner and the new partnership 'Edward Moore and Son' moved to offices at 3 Crosby Square. Another son was made a partner in 1890 and the style of the firm duly changed to 'Edward Moore and Sons'. In 1922 the company moved to 3 Thames House, Queen Street Place, in 1968 to 4 Chiswell Street and in 1988 to Clifford's Inn, Fetter Lane. The firm expanded in the 1970s opening a number of branch offices throughout England and Scotland. Edward Moore and Sons amalgamated with a number of practices in the 1970s and 1980s, most notably with Rowland Nevill of New Broad Street in 1985 to form the new company Moores and Rowland (from 1989 Moores Rowland).

Sewell, Hutchinson and Company: The company was formed in 1914 from C F Burton and Sewell and Company (itself formed in 1906) and acted as accountants until 1965 when the company was merged to form the group Rowland, Goodman, Sewell, Hutchinson and Sheen. It was based successively at Copthall Avenue (1914-15), Broad Street Place (1915-24) and Finsbury Pavement House, Moorgate (1925-65).

On Wilson's death in 1915, Henry and James Holmes took over the running of the practice, having previously acted independently from 60 Coleman Street. In 1972 Waissen Wilson merged with Westcott, Maskall and Company to form Westcott Wilson, based at 24 Grosvenor Gardens (1973), 1 Vincent Square (1974-9) and 87 Vincent Square (1980-1). This firm was taken over by Blakemore Elgar and Company in 1981, who merged with Moores Rowland in c.1995.

The practice moved to 99 Gresham Street (1888-1905); 29 and 30 Broad Street Avenue (1905-51); and 33 Catherine Place (1951-72).
