Biomass flue cleaning specialists, UK-wide

Why biomass flues are different

Wood chip and pellet systems foul faster than any domestic chimney and they fail differently. Deposits build in the flue way and start cutting efficiency long before anything triggers an alarm — so the first sign is usually a fuel bill, not a fault light.

Acidic condensate does the real damage. It attacks the flue wall from the inside, and by the time it’s visible from the outside you’re replacing sections rather than cleaning them.

What we do about it

Scheduled cleaning on an interval matched to your fuel and run hours, with a full internal inspection every visit. Every flue is condition-scored, photographed and documented, so deterioration shows up as a trend rather than a surprise.

No two biomass installs are the same. Professional rods and brushes only get you so far, so we design and make our own fittings, adaptors and vacuum mounts to suit each system — kit you can’t buy off the shelf.

We clean commercial oil boiler flues too, so a site with biomass and oil back-up has one contractor for every flue.

Every visit is written up

Each flue gets a condition score out of 100 across five areas — soot, obstruction, liner, structural integrity and defects — with photographs from inside the flue. Each boiler gets its own certificate, and a sticker on the boiler shows when it was last cleaned and when it’s next due.

Because the scoring is the same every visit, you can see a flue getting worse over a year or two and plan the repair, rather than finding out when it fails.
