Coyfield Ltd

COYFIELD is a UK ductwork and MVHR specialist for the construction sector, founded on a commitment to improve the coordination and quality of ventilation systems. They combine design rigour with directly-employed delivery teams to offer developers a single point of accountability from survey to handover. The company focuses on delivering premium ductwork and MVHR for a range of sectors including residential, build-to-rent, commercial, healthcare, and mixed-use schemes.

Their approach emphasizes design-led delivery, QA/QC first, and tailoring solutions to specific project needs, ensuring performance, buildability, and long-term running costs are considered. Their process involves a disciplined sequence: Assess (survey, design audit, value-engineering), Design (coordinated, compliant ductwork and MVHR design), Fabricate (DW/144 fabrication with traceability, pre-insulated modules), and Install & Maintain (accredited installation, leakage testing, commissioning support, and planned maintenance). COYFIELD aims to deliver air that is measured, balanced, and proven, with a focus on documented quality and engineering you can hold to account.
