Our history
Thames Valley Ventilation Limited was founded by Lenny Wingfield, a highly experienced heating, ventilation, and ductwork engineer with over 15 years of hands-on industry experience.
Lenny began his career serving his apprenticeship with Hotchkiss, gaining a solid foundation in ventilation installation and industry standards. Early in his career he worked on one of the UK’s most significant construction projects, Heathrow Terminal 5, followed by work on Terminal 2, developing valuable experience on complex large-scale ventilation systems.
Over the years, Lenny has contributed to a wide range of major projects across the UK and Europe, including high-specification data centre installations in Berkshire, London, Slough, and Frankfurt, Germany. These environments demand precision, reliability, and strict adherence to industry standards such as DW144 ductwork specifications.
After many years working on major commercial developments, Thames Valley Ventilation Limited was established to bring that same level of professional installation, workmanship, and reliability to both commercial and domestic ventilation projects.
Today, the company focuses on delivering high-quality ventilation solutions, including ductwork installation, MVHR systems, and ventilation upgrades, combining large-project expertise with a personal, reliable service.
