Gas Flue Collector Boxes

We have manufactured and supplied single wall and twin wall gas flue collector boxes for over 30 years to the chimney flue industry.  If you are a stockist or flue manufacturer requiring your own designs then contact us for a quote as we are also able to offer a bespoke service.   We have an efficient manufacturing process which means we can produce quality products at a competitive price, either to your own specifications or our own recommendations to BS 7977-1:2009 (Specification for safety and rational use of energy domestic gas appliances - Part 1: Radiant/convectors) and BS 715:2005 (Specification for metal flue boxes for gas-fired appliances not exceeding 20kw).
