Leading the Way in Biomass Heating Solutions Since 2012

Dunster Energy is one of the UK’s leading installers of biomass boilers. We have been operating in the field for since 2012, employing only the best in the industry. We pride ourselves on our knowledge, workmanship and efficiency – you can expect 100% customer service guarantee by choosing us.

At Dunster Energy we evaluate, design, build, install and maintain biomass boilers tailored to your needs. We operate in England, Scotland and Wales.


Our installations are based on five essential foundations

  • Continuous improvement – At Dunster, we don’t rest on our laurels. We continually look to refine and better our system design. We are always searching for the finest system components and optimal technology.
  • Value for money – Our systems are not the cheapest on the market, but we believe they offer the best value for money. We think an investment in lasting efficiency, usability and reliability is what makes sense in the long-term. We devote expertise to finding the best financial returns for each customer’s circumstances.
  • Quality – We take no shortcuts on system design. The system parts we use have been chosen following years of research. We use the highest-quality equipment, in order to maximize efficiency levels over a course of many years.
  • Service – We are proud of every system we fit. We think of customer service as something that covers the long-term. Customers should expect continued support and expertise after installations.
  • Integration – We provide fully-integrated systems, where each part of the installation is fitted to the demands of a given property. Our focus is always to make a system cohere as a whole. We sell systems, not just a boiler.

Skilled professionals committed to excellence in every biomass installation.

Biomass heating is a renewable, sustainable energy source that reduces carbon emissions and reliance on fossil fuels. It offers consistent, reliable heat and can lower energy costs, especially for businesses aiming to meet green energy targets.

Of course our installation teams would be nothing without the organisation and support of the office administration team, which also follows our in-house training programme, ensuring whoever you speak to at Dunster will be able to help.

Our Directors, Brendon Frost and Andrew Nixon, have a wealth of experience and knowledge between them, which is continuously transferred to the full team.

Brendon was raised on biomass heating. The house he grew up in (just outside of Dunster) was heated by a log boiler, and his father, Clifford, started one of the country’s first biomass heating companies. HETAS-qualified, with over a decade’s experience installing biomass boilers, and having travelled Europe specifically to research the technology behind them, Brendon’s industry expertise is prodigious.

Andrew delved into Biomass in the late 2000’s, initially distributing a Danish brand of boiler in the UK. This progressed into becoming a technical lead for ETA boilers, commissioning and supporting other installers for 100’s of installations around the UK. Andrew joined Dunster in 2022, bringing his knowledge and skills to all aspects of the business.
