PHG Consulting


The business was set up by Pierre Grigorian, a chartered civil and structural engineer who had been a salary director in a medium sized firm of consulting engineers in Cardiff for several years. Following disagreements with respect to the final cost of succession of that business, he set up PHG Consulting instead. The firm has since grown organically, establishing a highly regarded reputation in the industry.

Success Factor

Originally focusing on structural engineering, the business has grown since an experienced civil engineer was persuaded to join PHG as a business partner and the combination of the two elements led to far larger commissions and to more work in general. As a result, the civil engineering part of the business has expanded rapidly thanks to the already good reputation established by the structural portion of the PHG business. Since then, the transition into new offices on Cowbridge Road East in Cardiff - which was bought after the firm outgrew its first office – has been critical but has moved the business onto another level in terms of facilities and presence in the market place.

The Future

Having undertaken the major step of moving into the new office, there are several plans for the future. PHG has set up a second related company undertaking two separate aspects which include new research and development and new housing developments that will be undertaken on a carbon zero basis. It will also look to broaden the management and change the structure of the firm to an employee-owned trust which will formally set in place the founding principles that have been so successful. Other regional offices may follow in places like London and examine overseas opportunities where they may arise.
