Wyatt was now the principal architect of the day, the recipient of more commissions than he could well fulfil. His widespread practice and the duties of his official posts left him little time to give proper attention to the individual needs of his clients. As early as 1790, when he was invited to submit designs for rebuilding St Chad's Church at Shrewsbury, he broke his engagements with such frequency that the committee "became at length offended, and addressed themselves to Mr. George Stewart". In 1804, Jeffry Wyatt told Farington that his uncle had lost "many great commissions" by such neglect. When approached by a new client, he would at first take the keenest interest in the commission, but when the work was about to begin he would lose interest in it and "employ himself upon trifling professional matters which others could do". His conduct of official business was no better than his treatment of his private clients, and there can be no doubt that it was Wyatt's irresponsible habits which led to the reorganization of the Board of Works after his death, as a result of which the Surveyor's office was placed in the hands of a political chief assisted by three "attached architects".
