Welcome to BIVOR - British Industrial Flue Engineering at Its Best.

At BIVOR, we specialise in the design, manufacture, and installation of industrial boiler flues, CHP flue systems, and high-performance exhaust solutions for commercial and industrial environments.

We take on a carefully managed number of projects, allowing us to give every job our full attention from start to completion. By staying focused rather than juggling multiple installations, we can maintain the precision, workmanship and service our customers expect.

Our flue systems are manufactured right here in England, giving us full control over quality and allowing us to offer significantly shorter lead times compared to companies reliant on overseas production.

We’re proud to be a British company building British products, engineered for durability, safety, and efficiency across the UK’s toughest industrial environments.

Our Services

Our construction and maintenance services are dedicated to delivering exceptional quality and reliability. With a team of seasoned professionals, we ensure every project is executed with precision and expertise.

Reliable, safe, and fully compliant boiler flue systems for commercial and industrial premises.
We install stainless steel single-wall and twin-wall fire-rated systems, certified to H1 pressure class for high-performance, high-temperature applications.
Expert installation of flue systems for CHP units, standby generators, and engine-driven equipment.
We handle high-temperature, high-demand exhaust setups with precision and safety.
Data centres rely on standby generators to maintain critical operations during power outages. BIVOR provides specialist flue and exhaust installation for these systems, from individual generators to large multi-generator projects. When these systems are needed, there is no room for compromise - our focus is precision, reliability and getting it right first time.
At BIVOR, we take pride in delivering reliable flue systems with short lead times and a right-first-time approach.
Where many companies rely on generic model-based drawings that often lead to problems on site, we take a different path.
We carry out detailed, precise on-site measurements, ensuring the flue is manufactured to fit perfectly the first time.
And if an unexpected issue does arise during installation, we can resolve it quickly.
That’s because our flue systems are manufactured here in Britain, allowing rapid adjustments, minimal delays, and a smoother installation process from start to finish.
