Buying boiler flues at Plumb Supply
Our boiler flues range sits within flues & chimneys, part of the wider heating department. Every price is shown ex VAT by default so it matches the figures you quote on, with inc VAT available from the toggle. Use the filters to narrow by brand, price band or availability, and check the specification on each product page before you order.
Check the specification first
Sizes, connections and outputs vary between manufacturers. Open the product page and confirm the dimensions and fittings against your existing installation before ordering.
Buy the consumables together
Ordering fittings, valves, chemicals and fixings on the same order keeps you above the free delivery threshold and saves a second trip to site.
Quoting a larger job?
Send us the drawings or a materials list and our team will price the whole schedule, so you're comparing one figure rather than line-by-line.
