Explore our history

We've supported the UK through times of war and peace, prosperity and recession, political and regulatory upheaval. We've proudly stood beside the institutions and businesses which make the UK what it is.

Our founder believed in our profession's potential to be a force for good in society as well as the economy. Over the years, we've held onto that idea, striving to break down barriers inside the firm and make a difference outside.

James Marwick


James Marwick (the 'M' in KPMG) starts an accounting firm in Glasgow, qualifying as a Chartered Accountant in 1886. His career took him to New York – via Australia and Canada – where he opened a practice in 1895. In 1910, Peat and Marwick met aboard the RMS Lusitania in the mid-Atlantic and agreed to merge.

King Edward VII


The firm's long history of working with the Royal Family begins. Our founder William Barclay Peat, was appointed as auditor of the Privy Purse by King Edward VII. The firm's partners have now served five monarchs.

During the six-day voyage, the two men find they had much in common, including a shared perspective on professional values, and on 8 October 1910, Peat and Marwick agree to merge aboard the Lusitania. They first adopt Marwick, Mitchell & Peat and later become Peat, Marwick, Mitchell & Co.

Into the wars

The brewery Allsopp & Sons look to Peat to save it from bankruptcy in 1911. Peat turns things around for Allsopp – by 1916 they reported profits in the millions in today's money. The company became part of the Carlsberg Group in the early 1990s.
