This Page Doesn’t Exist (Yet)

But Grun Engineering definitely does.

​

We specialise in the design, supply, installation, and commissioning of commercial and industrial flue systems across the UK.

  • That includes:

  • Generator flues

  • Boiler Flues

  • CHP flues

  • Biomass flues

  • Water heater flues

  • Twin wall, single wall, high pressure, condensing and flexible systems

  • Smoke testing, pressure testing, and full system sign-off

​

We also handle flue removals and can recommend scaffolders, builders, couriers — whatever’s needed to get the job done right.

​

What to Expect From Our Website (Soon)​

  • Project examples

  • Full list of services

  • Our story and team

In the meantime, if you’ve got a flue problem — we’ve probably seen it before.
