What Bs Holdings Ltd does

BSH Limited, trading as BSH Heating & Cooling, is a privately held Northern Ireland engineering firm founded in 1970 that designs, manufactures, and installs energy plantrooms, warm air heating systems, and hydrogen technologies for commercial, industrial, and public sector clients across the UK and Ireland. The company's core offering centres on offsite-fabricated modular energy plantrooms — plug-and-power units integrating heating, cooling, combined heat and power (CHP), and increasingly hydrogen-compatible systems, with the largest units reaching 12m x 3.5m x 3m and 1.4MW thermal capacity. Complementary product lines include gas and oil-fired warm air heating systems (with particular depth in automotive showroom applications subject to complex petroleum service area regulations) and absorption chilling systems that use heat rather than electricity as the primary power source.

The business model is predominantly project-based, with bespoke engineering, offsite fabrication, and on-site commissioning delivered through direct enterprise sales to clients including Rolls Royce, Ferrari/Charles Hurst, Tesco, Ford, Lookers PLC, Taggarts PLC, Linamar, multiple UK and Irish councils, and universities. BSH operates as the UK main dealer for Sime UK/Italy (since 1970) and a representative for Atmos Boilers, Powrmatic HVAC, and Yazaki Absorption, generating equipment resale revenue alongside project work. Pricing is bespoke and not publicly disclosed. Revenue is not publicly reported, and the firm operates with a very small team of 1-10 employees.

Strategically, BSH has positioned itself at the early stage of the hydrogen transition, having launched The Penta hydrogen fuel cell system (100kW to grid scale), initiated development of Compression Electrochemical Hydrogen Compression (EHC) with Queens University Belfast, collaborated with national grid operators on a planned zero-emission power station for Northern Ireland, and built the first two hydrogen training rooms in the UK and Ireland for Gas Safe Engineers. The firm claims first-mover status as the only UK operator of four Sime hydrogen-blend boilers and as the installer of the first warm air heater on a hydrogen-blended natural gas line in the UK and Ireland, with an industry award for designing Europe's largest trigeneration plant room (Tesco, Naas, 2012).

• Sime UK / Sime ItalycoreChannel Partner/ Reseller/ Distributor · 1 January 1970BSH is a main dealer and trade representative of Sime UK and Sime Italy since 1970. Sime has more recently ventured into hydrogen with BSH as the only UK company to utilise four of their boilers to use mixed gas hydrogen as a fuel. BSH specifies and installs cast iron condensing boilers and upgrades, ranging from domestic to large commercial 18kW to 2MW individual boilers.
• Powrmatic HVACcoreChannel Partner/ Reseller/ DistributorPowrmatic has been a leading force in large space commercial heating since the early 1970s. BSH represents Powrmatic HVAC in Northern Ireland, delivering complete climate control HVAC solutions including warm air heating systems.
• Atmos BoilerscoreChannel Partner/ Reseller/ DistributorBSH represents boiler manufacturer Atmos across the UK, Ireland, and the East Coast of the United States of America. The Atmos range extends from wood fuelled to pellet fuelled, hybrid or conventional boilers, all complying with latest EU legislations for energy efficiency and emissions.
• Yazaki AbsorptioncoreTechnology or IntegrationBSH has been providing Yazaki Absorption chilling technologies for decades. These chillers primarily utilise heat as their main power source, making them a key provider of low carbon chilling for buildings or processes. BSH has received awards for creative designs featuring absorption chilling solutions.
• Queens University BelfastcoreStrategic or Co-development PartnerBSH is collaborating with Queens University Belfast on the Compression Electrochemical Hydrogen Compression (EHC) technology — a novel method that compresses and purifies hydrogen in a single step without moving parts. This collaboration is at a low technology readiness level (TRL) with the first EHC unit fabricated for testing.
• National Grid OperatorscoreStrategic or Co-development PartnerBSH is collaborating with national grid operators to bring a zero-emission power station to Northern Ireland, providing the designs and hybrid working systems to achieve this. The Penta hydrogen fuel cell system (ranging from 100kW to national grid scale) is central to this initiative.

Direct peers

• Ideal Heating: Ideal Heating is a UK boiler manufacturer with domestic and commercial ranges, including hydrogen-ready models. It competes with BSH on commercial boiler supply and the UK hydrogen heating transition.
• Spie UK: Spie UK provides mechanical, electrical, and HVAC building services across commercial and industrial facilities. It competes with BSH on integrated MEP installations and energy plantroom delivery for similar enterprise and public sector customers.
• Baxi Heating UK: Baxi is a major UK boiler manufacturer with hydrogen-ready domestic and commercial boiler ranges. Like BSH, Baxi targets the UK decarbonisation upgrade cycle and is developing hydrogen-blend boiler offerings, making it a direct competitor for boiler supply and hydrogen-ready system installations.
• Powrmatic HVAC: Powrmatic is a UK specialist in commercial warm air heating and HVAC systems, and is one of BSH's core channel partners. It competes in the same commercial warm air heating niche, particularly for car showroom and industrial facilities, and is comparable in scale and vertical specialisation.
• Thermax Global: Thermax manufactures absorption chilling and heating systems using heat as the primary energy source, directly overlapping with BSH's absorption chiller offering for low-carbon commercial cooling and CHP-linked installations.

Broad incumbents

• Viessmann: Viessmann is a global heating and HVAC manufacturer with hydrogen-ready commercial boilers and heat pumps. It overlaps with BSH on hydrogen-blend commercial heating systems and represents a much larger incumbent that BSH must compete against for hydrogen transition projects.
• Johnson Controls: Johnson Controls is a global HVAC, building automation, and energy services incumbent with a large UK services footprint. It competes with BSH on commercial plantroom and integrated HVAC projects and has substantially greater scale and recurring service revenue.
• Bosch Thermotechnology: Bosch Thermotechnology (including Worcester) manufactures hydrogen-ready boilers and commercial HVAC systems for UK and European markets. It competes with BSH on commercial plantroom content and has greater scale and R&D resources for hydrogen product development.
• Cofely (ENGIE UK): ENGIE (formerly Cofely) is a major UK and European energy services and facilities management company delivering commercial heating, cooling, CHP, and decarbonisation projects. It competes with BSH on integrated energy plantroom and CHP installations for enterprise and public sector clients.

Others

• Sime (Sime UK / Sime Italy): Sime is BSH's primary boiler manufacturing partner since 1970 and supplies the cast iron condensing boiler range (18kW to 2MW) that BSH specifies and installs. It is comparable as the OEM underpinning BSH's plantroom content, and Sime's own hydrogen-blend programme directly enables BSH's hydrogen differentiation.
