How we work

We combine warehouse stock with direct‑from‑manufacturer supply so you get the fastest, most reliable route. For heavy goods, haulage networks deliver to the kerbside; please arrange help to move items inside.

  • Same/next working‑day dispatch where possible
  • Delivery confirmation and tracking where available
  • Clear guidance for pallet deliveries

Before you order

Unsure about parts or sizes? Send a photo of the fireplace, the flue exit, and a rough plan. We’ll confirm compatibility and build a parts list so you can order with confidence.

  • Free flue design (wood, multi‑fuel, gas)
  • Advice on MI‑Flex liners and twin‑wall routes
  • Weathering/roof flashing recommendations

Enquiry form

We just need your name and one contact method (phone or email). Everything else is optional.
