Large stainless steel industrial flue system on a commercial building

From multi-branch manifold designs to high-rise vertical runs, we handle complex industrial installations. Our team has experience with stainless steel, mild steel, and specialist alloy systems rated for continuous high-temperature operation. We design for minimal pressure loss and maximum service life.

Construction site with new flue installation in progress

We slot seamlessly into multi-trade construction programmes, coordinating with architects, M&E consultants, and main contractors. Our pre-fabricated approach minimises on-site time and disruption. We've worked on projects ranging from care homes and schools to hotel chains and retail developments.

Building regulations documents and compliance certificates

Commercial flue installations face stringent regulatory requirements. We prepare comprehensive documentation including design calculations, material certificates, and commissioning reports. Our team liaises directly with Building Control officers to ensure smooth sign-off on every project.

Engineer testing flue gas emissions with calibrated equipment

Every commercial installation is commissioned with calibrated electronic analysers measuring CO, CO₂, O₂, draft pressure, and flue gas temperature. We provide formal test reports that satisfy equipment manufacturers, insurance underwriters, and regulatory bodies.

Technician performing maintenance on a commercial flue system

We offer annual maintenance contracts for commercial clients, including visual inspections, joint integrity checks, and CCTV internal surveys. For remedial work, we diagnose issues like poor draft, condensate damage, and structural deterioration — then design and deliver a permanent fix.
