PHD Mechanical Ltd was formed in 1978 as a mechanical contracting company. Based in Harrow, Middlesex, PHD Mechanical has grown steadily since its formation, and presently services homes and businesses across Middlesex and London. The company has a strong base in bid market projects, negotiated projects as well as commercial/industrial service and maintenance agreements. The company is well thought of by the area's contractors, architects and engineers. In recent years, our reputation has precluded us from having to secure bonds for most of our contracting projects. We do, however, have the capacity to secure any reasonable request for surety support. We believe we have a uniquely competitive edge in our industry because of the quality and organization of our facilities, our highly-trained technical staff and our management expertise.
