The company was established by Eric Faithful and Leonard Gould in 1947 as they worked together to repair Bristol after it was heavily bombed during the Second World War.

[2] Faithful+Gould formed links with various other companies; examples include Imperial Chemical Industries (ICI), where it provided cost valuation and management services across its UK operations, and the National Coal Board, where it aided in the development of Selby Coalfield.

[2] During early 1996, the company was acquired by Atkins via a combined cash and shares deal valued at £21 million; it operated as a subsidiary of the firm thereafter.

[13] In January 2011, Faithful+Gould, together with its parent company Atkins, formed a new consultancy unit aimed at addressing green development and environmental queries.

[18] During November 2012, the Bank of Ireland took legal action against Faithful+Gould, seeking £9.9 million over alleged failing related to an abandoned tower project in Manchester.
