  •  I would just like to pass on our thanks to Peter, for getting our heating up and running last night. He truly went the extra mile, and made sure all things checked out before he left our building. He's a true asset to your company, and I only wished all contractors had the same commitment to there customers. Thank you once again, brilliant service!!!

    Academy- January 2024

  • You have shown us what a good (excellent!) biomass boiler installation looks like. You have become an essential partner in our net-zero aspirations.
    You have set a new standard for heating system efficiency. You have set a new standard when it comes to working collaboratively with suppliers.

    Public sector customer

  • BBSM installed the first of our biomass boilers in 2021. We found the company to be very reliable, trustworthy, and they worked efficiently and to a high standard. Based on our experience, we asked BBSM to install our second, and then our third biomass boiler system.
    We have engaged BBSM to carry our on-going scheduled service and maintenance. I would highly recommend them.

    Industrial customer

  • BBSM's team responded with flexibility and with great professionalism when the scope of the project had to be amended due to circumstances outside of their control, and always demonstrated a solutions led approach.
    We could not be happier with the outcome of the project. The new boiler is delivering significant fuel savings and takes considerably less time from our on site team to maintain. In fact, the project has been so successful we have subsequently contracted BBSM to extend the biomass system to provide hot water to a block of holiday apartments on the same site. I would be happy to recommend BBSM unconditionally.

    Hotel customer

  • BBSM were a professional company to work with. They stood behind their work, and we are very happy with the installation, their continued support, and their level of service.
