Who are we?

Wessex Biomass is an independent and experienced supplier and installer of biomass heating systems, serving both the domestic and non-domestic market sectors. We operate in Wiltshire and its surrounding counties; as a rule of thumb, we undertake projects within a 90 minute drive of the M4 at junction 17. There is a very good reason for this, it is because we fully support our installations, contracturally for 2 years but, in reality, for much longer; with support and advice on RHI applications, servicing, spare parts, clients' growing renewable needs and much more!

For your benefit and peace of mind, we hold full MCS Accreditation (essential for claiming the Renewable Heat Incentive - RHI), in addition to both RECC and HETAS Accreditations and are members of the REAL Workmanship Guarantee Assurance Scheme.

The Principals of the company have experience and expertise in different yet complementary areas of the market, which means that your journey towards cleaner, greener and cheaper heating begins with us, at that very first point of contact, right through the design and survey stage and onto installation, commissioning and beyond; indeed, we are still advising, supporting and carrying out services for happy clients from our early installation days back in 2009.

Why are we different?

We specialise in biomass, it is our main area of expertise and we are unapologetically enthusiastic about it.

We pride ourselves on the superior customer service experience that we offer. Our clients are our greatest advocates and assets, don't take our word for it, have a look at the videos on this site to see what our clients have to say about us or ask us to arrange a site visit to an existing client's installation, where you can talk candidly about biomass and about us.

We will not make outlandish statements about fuel savings and financial cashbacks in order to gain your business. Our figures are circumspect and achievable and based on fact not conjecture. We believe that the government incentives make more than enough financial sense in themselves and do not need to be inflated or misrepresented.

We have been happily and successfully designing, installing and maintaining biomass systems since 2009.

For your peace of mind we are MCS, RECC and HETAS accredited and members of the REAL workmanship and warranty assurance scheme.

We will never recommend a system to you for any other reason than because it is the right system for you and your budget.
