Nottinghamshire architect erased from Architects Register following criminal convictions and unacceptable professional conduct

June 10, 2021 | News Release

Serious concerns about architects are rare. On the limited occasions they do occur, as the UK regulator we are here to ensure standards, and therefore trust, in the profession is maintained. We hope the information published about conduct and competence decisions provides useful learning points for others.

Mr Jonathan Colin Muirhead of Newark, Nottinghamshire has been erased from the Architects Register following a hearing of ARB’s independent Professional Conduct Committee (PCC) on 29-30 March 2021 and 28 May 2021.

Mr Muirhead had received six criminal convictions spanning a period of over two years. These included offences of drink driving, failure to surrender to custody and multiple counts of assault by beating. Mr Muirhead had failed to disclose these convictions to the ARB. The ARB alleged that Mr Muirhead’s convictions were relevant to his fitness to practise as an architect because of the nature and seriousness of the offences, which demonstrated ‘violence and a disregard to the safety of others.’ 

Mr Muirhead partially attended the hearing in person.  The PCC noted that Mr Muirhead did not dispute any of the convictions but argued that these were not material to his fitness to practise. The found that the convictions were material to Mr Muirhead’s fitness to practise as they called into question his integrity and brought the reputation of the profession into disrepute.

The PCC also found the allegations of UPC proved and considered that Mr Muirhead had not acted with honesty and integrity by failing to promptly and fully declare his convictions. It found that he had sought to mislead ARB about the extent of his criminal offences. The PCC found that his conduct constituted a breach of Standard 1.1 and 9.4 of the Architects Code. The PCC considered his actions represented a serious departure from the standard expected of an architect and amounted to unacceptable professional conduct.

When considering sanction, the PCC noted Mr Muirhead had no previous regulatory findings. The Committee acknowledged the offending arose at a very difficult time for Mr Muirhead however he had shown no insight into the effect of his conduct and that the convictions were numerous and demonstrated an escalating pattern of behaviour between 2018 and 2020. It concluded that Mr Muirhead’s conduct was fundamentally incompatible with remaining on the Register and that in the interest of the reputation of the profession, Mr Muirhead’s name should be removed from the Architects Register.  As he is no longer registered with ARB, he can no longer practise as an architect in the UK.
