JHH Engineering

JHH Engineering Ltd was formed in 1996, to cover its founder's engineering activities in the commissioning of large-scale industrial plant. In early 2003 it diversified to cover pre-handover inspection and certification of roofing system membranes. Also that year, it further enlarged its portfolio of operations to cover independent inspections and consultancy within the building and construction industry, predominantly relating to roof inspections / surveys and water ingress issues in particular. In January 2009, JHH Engineering was awarded UKAS accreditation, under ISO/IEC 17025 (testing laboratory No 4255), the first roof testing company to be recognised in this way, for the quality of its testing.
