We operate throughout Somerset, Devon, Dorset, Cornwall, Gloucestershire, and Wiltshire. Emergency callouts are available across the South West for boiler breakdowns and system failures.
How efficient are biomass boilers?
Modern biomass boilers achieve over 90% efficiency. We install high-efficiency models that qualify for RHI payments, with options for wood chip, pellet, and log systems tailored to your property's requirements.
What maintenance do boilers require?
Annual servicing is required for RHI compliance. This includes combustion analysis, component inspection, and water treatment. We offer service contracts with fixed annual fees and priority emergency support for all commercial clients.

Report
Work carried out OK but incredibly expensive for a domestic customer. I had a dispute about my supposed guarantee and was left completely on my own arguing with ETA, who didn't want to know. Think I paid 720 for just over 2 hours onsite and a 100 part. Did the service ok though.
