Commercial Boiler Installation London

Priory Gas Heating Ltd specialises in commercial boiler installation across London, delivering compliant, energy-efficient systems from 100kW to over 1000kW. We handle new plantrooms, upgrades, and full replacements using trusted brands like Hamworthy, Ideal, and Vaillant, with full design, commissioning, and documentation included.

What Our Service Includes

We manage the full process of commercial boiler installation, from initial assessment through to commissioning and handover. Every installation is tailored to the building’s heating requirements, with a focus on energy efficiency, compliance, and long-term performance. Our work follows industry best practice and manufacturer guidelines at each stage.

  • Initial site visit and system assessment – We evaluate your existing heating setup and site conditions to plan a compliant and efficient boiler installation.
  • Heat load calculations and boiler sizing – We determine the correct boiler output for your building’s heating demands using accurate sizing methods.
  • Commercial boiler supply and installation – We install Hamworthy, Ideal, and Vaillant commercial boilers, tailored to projects from 100kW to 1000kW+.
  • Plantroom layout and pipework design – We design plantroom pipework and layout to ensure clear access, safe operation, and long-term reliability.
  • Integration with existing heating systems – We connect new commercial boilers to existing distribution and control systems where required.
  • Commissioning and testing – We carry out full commissioning of the boiler and associated equipment, with gas safety and performance checks.
  • Project documentation and handover – We provide commissioning sheets, manuals, and certification as part of the final handover. We install cast iron Hamworthy Purewell Variheat mk2 boilers as standard for high-load, low-maintenance applications, with options for Ideal and Vaillant systems as appropriate.

Efficiency & Environmental Considerations

Our commercial boiler installations are designed to maximise energy efficiency and reduce long-term operating costs. We install condensing boilers with low-NOx performance to meet current environmental standards and improve carbon outcomes. Systems are carefully sized to avoid energy waste and overcapacity. During installation, old equipment is removed by licensed waste contractors who recycle materials wherever possible, including steel casings, copper pipework, and electronic controls. All new systems are configured to meet Part L requirements and offer measurable savings in both energy and maintenance.
