Lime Kiln Leisure Centre and Warminster Sports Centre

Replaced aging gas boilers at two leisure centres with high efficiency wood pellet boiler systems. Turn-key installation under CDM including all building works and landscaping. Leisure centre decreased energy usage by 50%.

Installation of 2 No. Hargassner 330kW wood pellet boilers to replace old gas-fired boilers.


Lime Kiln is a popular sports centre and public swimming pool providing recreation for the community of Royal Wootton Bassett in Wiltshire. The pool and buildings were heated with two gas boilers each rated at 400kW each which provided hot water for the showers in the changing rooms.

Wiltshire Council (WC) has committed to being a carbon neutral organisation by 2030. The gas boilers at Lime Kiln were over 20 years old and, as part of the decarbonisation programme, it was decided to replace the aging gas boilers with new state-of-the-art biomass pellet boilers.


To provide essential, low cost year-round reliable heating solutions for the community leisure centre by replacing the inefficient aging gas boilers with high efficiency, wood pellet, biomass boiler systems. The project was a turn-key installation under CDM including all building works and landscaping.


BBSM Ltd selected two Hargassner 330kW pellet boilers due to their high quality and efficiency and because of their compact nature meaning the installation was possible with the existing plant room.

The whole project was completed within four months and now operates 100% on biomass, with no gas boilers being present.

An analysis of the first 12 months of operation showed that the primary energy usage for heating the site dropped by a staggering 50%, making large savings for Wiltshire Council. In 2023 BBSM were awarded the long-term service and maintenance contract for the entire biomass portfolio of the council.

  •  I would just like to pass on our thanks to Peter, for getting our heating up and running last night.

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.
