About Us

Commercial Biomass Ltd offers a wide range of renewable energy technologies at affordable prices. We strive to make these products accessible to all our customers and can help you choose the right options to suit you, your budget and your lifestyle.

We act as a one-stop-shop for our customers who are wanting to explore using renewable energy to heat their commercial premises or homes. Whether you are looking at this type of heating as a commercial or residential customer, Commercial Biomass will be able to work out the best solution for you at the best price.


We can carry out an energy audit for you and advise on which steps you could take to cut your energy bills and which technologies would best suit your property or business. If you are planning a new build we can also advise on how best to maximise your energy savings through design, use of materials and technologies. You will get impartial advice together with costings for each measure and an estimate of savings from that measure, from which we can work out your payback period.
As part of our installation service we do your RHI applications for you and guide you through your first meter readings and submissions. We understand that form filling and applications for grants can be daunting if you have never done it before, which is why we simplify the process for you and get it done and out of the way without you having to worry about it. No fuss, no hassle.


We can help with funding, whatever your situation.


We can project manage all aspects of your installation from the planning stages to completion. Turnkey packages are available where we take responsibility for all trades, giving you the benefit of a single point of contact for steering your project instead of having to manage multiple contractors.


Our team of highly trained maintenance engineers provide annual servicing and backup if you should experience a breakdown. Several levels of service are available, from a fixed annual fee to an ‘as and when you need us’ service on an hourly rate. ETA boilers come with a one year parts and labour guarantee plus a four year parts guarantee, which covers all parts of the boiler, giving you five years peace of mind included within the cost of the boiler.

Our Team

You are making a substantial investment, so you naturally want to make sure the work is in safe and competent hands. Commercial Biomass Ltd employs a skilled workforce of men with decades of experience in the construction and mechanical services industries, and their eco credentials are second to none.

Commercial Biomass is uniquely qualified to work with a wide range of clients. The partners, Nigel Bell and Pete Downes, worked together on numerous ecologically friendly building developments before forming the partnership.

MD Pete Downes

Pete Downes started his working life by serving a full apprenticeship with a then FTSE100 HVAC and mechanical services company. He worked on a variety of high value commercial contracts, including hospitals, schools, hotels and factories, giving him a working knowledge of large industrial plumbing, heating and ventilation systems, as well as advanced craft qualifications.

He went on to start his own company, Triple A Services (SW) Ltd in 1989. In the years since, he has employed and organised his own teams of pipefitters, contracting on prestige contracts such as the PSA Patents Office in Newport, and the refurbishment of the Winter Gardens, Weston Super Mare, for Matthew Hall PLC and Colston Ltd, respectively. His programme of continued professional development has gained him numerous BPEC and BTEC qualifications in the fields of renewable energy and heat efficiency.  In addition to this his company has undertaken and successfully completed hundreds of plumbing and heating installations on housing projects from new build housing to multi-million pound mansion houses.

Pete  has been personally involved with the design and fitting of the ETA biomass heating systems on dozens of contracts, and enjoys working with clients to achieve the installation to suit their needs.
